+So you'd like to contribute to the `script` library? Excellent! Thank you very much. I can absolutely use your help.
+
+# Getting started
+
+Here are some hints on a good workflow for contributing to the project.
+
+## Look for existing issues
+
+First of all, check the [issues](https://github.com/bitfield/script/issues) list. If you see an outstanding issue that you would like to tackle, by all means comment on the issue and let me know.
+
+If you already have an idea for a feature you want to add, check the issues list anyway, just to make sure it hasn't already been discussed.
+
+## Open a new issue before making a PR
+
+I _don't_ recommend just making a pull request for some new feature—it probably won't be accepted! Usually it's better to [open an issue](https://github.com/bitfield/script/issues/new) first, and we can discuss what the feature is about, how best to design it, other people can weigh in with contributions, and so forth. Design is, in fact, the hard part. Once we have a solid, well-thought-out design, implementing it is usually fairly easy. (Implementing a bad design may be easy too, but it's a waste of effort.)
+
+## Write a use case
+
+This is probably the most important thing to bear in mind. A great design principle for software libraries is to start with a real-world use case, and try to implement it using the feature you have in mind. _No issues or PRs will be accepted into `script` without an accompanying use case_. And I hold myself to that rule just as much as anybody else.
+
+What do I mean by "use case"? I mean a real problem that you or someone else actually has, that could be solved using the feature. For example, you might think it's a very cool idea to add a `Frobnicate()` method to `script`. Maybe it is, but what's it for? Where would this be used in the real world? Can you give an example of a problem that could be solved by a `script` program using `Frobnicate()`? If so, what would the program look like?
+
+The reason for insisting on this up front is that it's much easier to design a feature the right way if you start with its usage in mind. It's all too easy to design something in the abstract, and then find later that when you try to use it in a program, the API is completely unsuitable.
+
+A concrete use case also provides a helpful example program that can be included with the library to show how the feature is used.
+
+The final reason is that it's tempting to over-elaborate a design and add all sorts of bells and whistles that nobody actually wants. Simple APIs are best. If you think of an enhancement, but it's not needed for your use case, leave it out. Things can always be enhanced later if necessary.
+
+# Coding standards

+A library is easier to use, and easier for contributors to work on, if it has a consistent, unified style, approach, and layout. Here are a few hints on how to make a `script` PR that will be accepted right away.
+
+## Tests
+
+It goes without saying, but I'll say it anyway, that you must provide comprehensive tests for your feature. Code coverage doesn't need to be 100% (that's a waste of time and effort), but it does need to be very good. The [awesome-go](https://github.com/avelino/awesome-go) collection (which `script` is part of) mandates at least 80% coverage, and I'd rather it were 90% or better.
+
+Test data should go in the `testdata` directory. If you create a file of data for input to your method, name it `method_name.input.txt`. If you create a 'golden' file (of correct output, to compare with the output from your method) name it `method_name.golden.txt`. This will help keep things organised.
+
+### Use the standard library
+
+All `script` tests use the standard Go `testing` library; they don't use `testify` or `gock` or any of the other tempting and shiny test libraries. There's nothing wrong with those libraries, but it's good to keep things consistent, and not import any libraries we don't absolutely need.
+
+You'll get the feel of things by reading the existing tests, and maybe copying and adapting them for your own feature.
+
+All tests should call `t.Parallel()`. If there is some really good reason why your test can't be run in parallel, we'll talk about it.
+
+### Spend time on your test cases
+
+Add lots of test cases; they're cheap. Don't just test the obvious happy-path cases; test the null case, where your feature does nothing (make sure it does!). Test edge cases, strange inputs, missing inputs, non-ASCII characters, zeroes, and nils. Knowing what you know about your implementation, what inputs and cases might possibly cause it to break? Test those.
+
+Remember people are using `script` to write mission-critical system administration programs where their data, their privacy, and even their business could be at stake. Now, of course it's up to them to make sure that their programs are safe and correct; library maintainers bear no responsibility for that. But we can at least ensure that the code is as reliable and trustworthy as we can make it.
+
+### Add your method to `doMethodsOnPipe` for stress testing
+
+One final point: a common source of errors in Go programs is methods being called on zero or nil values. All `script` pipe methods should handle this situation, as well as being called on a valid pipe that just happens to have no contents (such as a newly-created pipe).
+
+To ensure this, we call every possible method on (in turn) a nil pipe, a zero pipe, and an empty pipe, using the `doMethodsOnPipe` helper function. If you add a new method to `script`, add a call to your method to this helper function, and it will automatically be stress tested.
+
+Methods on a nil, zero, or empty pipe should not necessarily do nothing; that depends on the method semantics. For example, `WriteFile()` on an empty pipe creates the required file, writes nothing to it, and closes it. This is correct behaviour.
+
+## Dealing with errors
+
+Runtime errors (as opposed to test failures or compilation errors) are handled in a special way in `script`.
+
+### Don't panic
+
+Methods should not, in any situation, panic. In fact, no `script` method panics, nor should any library method. Because calling `panic()` ends the program, this decision should be reserved for the `main()` function. In other words, it's up to the user, not us, when to crash the program. This is a good design principle for Go libraries in general, but especially here because we have a better way of dealing with errors.
+
+### Set the pipe's error status
+
+Normally, Go library code that encounters a problem would return an error to the caller, but `script` methods are specifically designed not to do this (see [Handling errors](README.md#Handling-errors)). Instead, set the error status on the pipe and return. Before you do anything at all in your method, you should check whether the pipe is nil, or the error status is set, and if so, return immediately.
+
+Here's an example:
+
+```go
+func (p *Pipe) Frobnicate() *Pipe {
+ // If the pipe has an error, or is nil, this is a no-op
+ if p == nil || p.Error() != nil {
+ return p
+ }
+ output, err := doSomething()
+ if err != nil {
+ // Something went wrong, so save the error in the pipe. The user can
+ // check it afterwards.
+ p.SetError(err)
+ return p
+ }
+ return NewPipe().WithReader(bytes.NewReader(output))
+}
+```
+
+## Style and formatting
+
+This is easy in Go. Just use `gofmt`. End of.
+
+Your code should also pass `golint` and `go vet` without errors (and if you want to run other linters too, that would be excellent). Very, very occasionally there are situations where `golint` incorrectly detects a problem, and the workaround is awkward or annoying. In that situation, comment on the PR and we'll work out how best to handle it.
+
+# Documentation
+
+It doesn't matter if you write the greatest piece of code in the history of the world, if no one knows it exists, or how to use it.
+
+## Write doc comments
+
+Any functions or methods you write should have useful documentation comments in the standard `go doc` format. Specifically, they should say what inputs the function takes, what it does (in detail), and what outputs it returns. If it returns an error value, explain under what circumstances this happens.
+
+For example:
+
+```go
+// WriteFile writes the contents of the pipe to the specified file, and closes
+// the pipe after reading. If the file already exists, it is truncated and the
+// new data will replace the old. It returns the number of bytes successfully
+// written, or an error.
+func (p *Pipe) WriteFile(fileName string) (int64, error) {
+```
+
+This is the _whole_ user manual for your code. It will be included in the autogenerated documentation for the whole package. Remember that readers will often see it _without_ the accompanying code, so it needs to make sense on its own.
+
+## Update the README
+
+Any change to the `script` API should also be accompanied by an update to the README. If you add a new method, add it to the appropriate table (sources, filters, or sinks), and if it's the equivalent of a command Unix command, add it to the table of Unix equivalents too.
+
+# Before submitting your pull request
+
+Here's a handy checklist for making sure your PR will be accepted as quickly as possible.
+
+- [ ] Have you opened an issue to discuss the feature and agree its general design?
+- [ ] Do you have a use case and, ideally, an example program using the feature?
+- [ ] Do you have tests covering 90%+ of the feature code (and, of course passing)
+- [ ] Have you added your method to the `doMethodsOnPipe` stress tests?
+- [ ] Have you written complete and accurate doc comments?
+- [ ] Have you updated the README and its table of contents?
+- [ ] You rock. Thanks a lot.
+
+# After submitting your PR
+
+Here's a nice tip for PR-driven development in general. After you've submitted the PR, do a 'pre-code-review'. Go through the diffs, line by line, and be your own code reviewer. Does something look weird? Is something not quite straightforward? It's quite likely that you'll spot errors at this stage that you missed before, simply because you're looking at the code with a reviewer's mindset.
+
+If so, fix them! But if you can foresee a question from a code reviewer, comment on the code to answer it in advance. (Even better, improve the code so that the question doesn't arise.)
+
+# The code review process
+
+If you've completed all these steps, I _will_ invest significant time and energy in giving your PR a detailed code review. This is a powerful and beneficial process that can not only improve the code, but can also help you learn to be a better engineer and a better Go programmer—and the same goes for me!
+
+## Expect to be taken seriously
+
+Don't think of code review as a "you got this wrong, fix it" kind of conversation (this isn't a helpful review comment). Instead, think of it as a discussion where both sides can ask questions, make suggestions, clarify problems and misunderstandings, catch mistakes, and add improvements.
+
+You shouldn't be disappointed if you don't get a simple 'LGTM' and an instant merge. If this is what you're used to, then your team isn't really doing code review to its full potential. Instead, the more comments you get, the more seriously it means I'm taking your work. Where appropriate, I'll say what I liked as well as what I'd like to see improved.
+
+## Dealing with comments
+
+Now comes the tricky bit. You may not agree with some of the code review comments. Reviewing code is a delicate business in the first place, requiring diplomacy as well as discretion, but responding to code reviews is also a skilled task.
+
+If you find yourself reacting emotionally, take a break. Go walk in the woods for a while, or play with a laughing child. When you come back to the code, approach it as though it were someone else's, not your own, and ask yourself seriously whether or not the reviewer _has a point_.
+
+If you genuinely think the reviewer has just misunderstood something, or made a mistake, try to clarify the issue. Ask questions, don't make accusations. Remember that every project has a certain way of doing things that may not be _your_ way. It's polite to go along with these practices and conventions.
+
+You may feel as though you're doing the project maintainer a favour by contributing, as indeed you are, but an open source project is like somebody's home. They're used to living there, they probably like it the way it is, and they don't always respond well to strangers marching in and rearranging the furniture. Be considerate, and be willing to listen and make changes.
+
+## This may take a while
+
+Don't be impatient. We've all had the experience of sending in our beautifully-crafted PR and then waiting, waiting, waiting. Why won't those idiots just merge it? How come other issues and PRs are getting dealt with ahead of mine? Am I invisible?
+
+In fact, doing a _proper_ and serious code review is a time-consuming business. It's not just a case of skim-reading the diffs. The reviewer will need to check out your branch, run the tests, think carefully about what you've done, make suggestions, test alternatives. It's almost as much work as writing the PR in the first place.
+
+Open source maintainers are just regular folk with jobs, kids, and zero free time or energy. They may not be able to drop everything and put in several hours on your PR. The task may have to wait a week or two until they can get sufficient time and peace and quiet to work on it. Don't pester them. It's fine to add a comment on the PR if you haven't heard anything for a while, asking if the reviewer's been able to look at it and whether there's anything you can do to help speed things up. Comments like 'Y U NO MERGE' are unlikely to elicit a positive response.
+
+Thanks again for helping out!

+# What is `script`?
+
+`script` is a Go library for doing the kind of tasks that shell scripts are good at: reading files, executing subprocesses, counting lines, matching strings, and so on.
+
+Why shouldn't it be as easy to write system administration programs in Go as it is in a typical shell? `script` aims to make it just that easy.
+
+Shell scripts often compose a sequence of operations on a stream of data (a _pipeline_). This is how `script` works, too.
+
+> *This is one absolutely superb API design. Taking inspiration from shell pipes and turning it into a Go library with syntax this clean is really impressive.*\
+> —[Simon Willison](https://news.ycombinator.com/item?id=30649524)

+
+# Some examples
+
+Let's see some simple examples. Suppose you want to read the contents of a file as a string:
+
+```go
+contents, err := script.File("test.txt").String()
+```
+
+That looks straightforward enough, but suppose you now want to count the lines in that file.
+
+```go
+numLines, err := script.File("test.txt").CountLines()
+```
+
+For something a bit more challenging, let's try counting the number of lines in the file that match the string `Error`:
+
+```go
+numErrors, err := script.File("test.txt").Match("Error").CountLines()
+```
+
+But what if, instead of reading a specific file, we want to simply pipe input into this program, and have it output only matching lines (like `grep`)?
+
+```go
+script.Stdin().Match("Error").Stdout()
+```
+
+Just for fun, let's filter all the results through some arbitrary Go function:
+
+```go
+script.Stdin().Match("Error").FilterLine(strings.ToUpper).Stdout()
+```
+
+That was almost too easy! So let's pass in a list of files on the command line, and have our program read them all in sequence and output the matching lines:
+
+```go
+script.Args().Concat().Match("Error").Stdout()
+```
+
+Maybe we're only interested in the first 10 matches. No problem:
+
+```go
+script.Args().Concat().Match("Error").First(10).Stdout()
+```
+
+What's that? You want to append that output to a file instead of printing it to the terminal? *You've got some attitude, mister*. But okay:
+
+```go
+script.Args().Concat().Match("Error").First(10).AppendFile("/var/log/errors.txt")
+```
+
+And if we'd like to send the output to the terminal *as well as* to the file, we can do that:
+
+```go
+script.Echo("data").Tee().AppendFile("data.txt")
+```
+
+We're not limited to getting data only from files or standard input. We can get it from HTTP requests too:
+
+```go
+script.Get("https://wttr.in/London?format=3").Stdout()
+// Output:
+// London: 🌦 +13°C
+```
+
+That's great for simple GET requests, but suppose we want to *send* some data in the body of a POST request, for example. Here's how that works:
+
+```go
+script.Echo(data).Post(URL).Stdout()
+```
+
+If we need to customise the HTTP behaviour in some way, such as using our own HTTP client, we can do that:
+
+```go
+script.NewPipe().WithHTTPClient(&http.Client{
+ Timeout: 10 * time.Second,
+}).Get("https://example.com").Stdout()
+```
+
+Or maybe we need to set some custom header on the request. No problem. We can just create the request in the usual way, and set it up however we want. Then we pass it to `Do`, which will actually perform the request:
+
+```go
+req, err := http.NewRequest(http.MethodGet, "http://example.com", nil)
+req.Header.Add("Authorization", "Bearer "+token)
+script.Do(req).Stdout()
+```
+
+The HTTP server could return some non-okay response, though; for example, “404 Not Found”. So what happens then?
+
+In general, when any pipe stage (such as `Do`) encounters an error, it produces no output to subsequent stages. And `script` treats HTTP response status codes outside the range 200-299 as errors. So the answer for the previous example is that we just won't *see* any output from this program if the server returns an error response.
+
+Instead, the pipe “remembers” any error that occurs, and we can retrieve it later by calling its `Error` method, or by using a *sink* method such as `String`, which returns an `error` value along with the result.
+
+`Stdout` also returns an error, plus the number of bytes successfully written (which we don't care about for this particular case). So we can check that error, which is always a good idea in Go:
+
+```go
+_, err := script.Do(req).Stdout()
+if err != nil {
+ log.Fatal(err)
+}
+```
+
+If, as is common, the data we get from an HTTP request is in JSON format, we can use [JQ](https://stedolan.github.io/jq/) queries to interrogate it:
+
+```go
+data, err := script.Do(req).JQ(".[0] | {message: .commit.message, name: .commit.committer.name}").String()
+```
+
+We can also run external programs and get their output:
+
+```go
+script.Exec("ping 127.0.0.1").Stdout()
+```
+
+Note that `Exec` runs the command concurrently: it doesn't wait for the command to complete before returning any output. That's good, because this `ping` command will run forever (or until we get bored).
+
+Instead, when we read from the pipe using `Stdout`, we see each line of output as it's produced:
+
+```
+PING 127.0.0.1 (127.0.0.1): 56 data bytes
+64 bytes from 127.0.0.1: icmp_seq=0 ttl=64 time=0.056 ms
+64 bytes from 127.0.0.1: icmp_seq=1 ttl=64 time=0.054 ms
+...
+```
+
+In the `ping` example, we knew the exact arguments we wanted to send the command, and we just needed to run it once. But what if we don't know the arguments yet? We might get them from the user, for example.
+
+We might like to be able to run the external command repeatedly, each time passing it the next line of data from the pipe as an argument. No worries:
+
+```go
+script.Args().ExecForEach("ping -c 1 {{.}}").Stdout()
+```
+
+That `{{.}}` is standard Go template syntax; it'll substitute each line of data from the pipe into the command line before it's executed. You can write as fancy a Go template expression as you want here (but this simple example probably covers most use cases).
+
+If there isn't a built-in operation that does what we want, we can just write our own, using `Filter`:
+
+```go
+script.Echo("hello world").Filter(func (r io.Reader, w io.Writer) error {
+ n, err := io.Copy(w, r)
+ fmt.Fprintf(w, "\nfiltered %d bytes\n", n)
+ return err
+}).Stdout()
+// Output:
+// hello world
+// filtered 11 bytes
+```
+
+The `func` we supply to `Filter` takes just two parameters: a reader to read from, and a writer to write to. The reader reads the previous stages of the pipe, as you might expect, and anything written to the writer goes to the *next* stage of the pipe.
+
+If our `func` returns some error, then, just as with the `Do` example, the pipe's error status is set, and subsequent stages become a no-op.
+
+Filters run concurrently, so the pipeline can start producing output before the input has been fully read, as it did in the `ping` example. In fact, most built-in pipe methods, including `Exec`, are implemented *using* `Filter`.
+
+If we want to scan input line by line, we could do that with a `Filter` function that creates a `bufio.Scanner` on its input, but we don't need to:
+
+```go
+script.Echo("a\nb\nc").FilterScan(func(line string, w io.Writer) {
+ fmt.Fprintf(w, "scanned line: %q\n", line)
+}).Stdout()
+// Output:
+// scanned line: "a"
+// scanned line: "b"
+// scanned line: "c"
+```
+
+And there's more. Much more. [Read the docs](https://pkg.go.dev/github.com/bitfield/script) for full details, and more examples.
+
+# A realistic use case
+
+Let's use `script` to write a program that system administrators might actually need. One thing I often find myself doing is counting the most frequent visitors to a website over a given period of time. Given an Apache log in the Common Log Format like this:
+
+```
+212.205.21.11 - - [30/Jun/2019:17:06:15 +0000] "GET / HTTP/1.1" 200 2028 "https://example.com/ "Mozilla/5.0 (Linux; Android 8.0.0; FIG-LX1 Build/HUAWEIFIG-LX1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/64.0.3282.156 Mobile Safari/537.36"
+```
+
+we would like to extract the visitor's IP address (the first column in the logfile), and count the number of times this IP address occurs in the file. Finally, we might like to list the top 10 visitors by frequency. In a shell script we might do something like:
+
+```sh
+cut -d' ' -f 1 access.log |sort |uniq -c |sort -rn |head
+```
+
+There's a lot going on there, and it's pleasing to find that the equivalent `script` program is quite brief:
+
+```go
+package main
+
+import (
+ "github.com/bitfield/script"
+)
+
+func main() {
+ script.Stdin().Column(1).Freq().First(10).Stdout()
+}
+```
+
+Let's try it out with some [sample data](testdata/access.log):
+
+```
+16 176.182.2.191
+ 7 212.205.21.11
+ 1 190.253.121.1
+ 1 90.53.111.17
+```
+
+# A `script` “interpreter”
+
+One of the nice things about shell scripts is that there's no build process: the script file itself is the “executable” (in fact, it's interpreted by the shell). Simon Willison (and GPT-4) contributed this elegant `script` interpreter, written in `bash`:
+
+* [`go-script`](https://til.simonwillison.net/bash/go-script)
+
+With `go-script`, you can run `script` one-liners directly:
+
+```sh
+cat file.txt | ./goscript.sh -c 'script.Stdin().Column(1).Freq().First(10).Stdout()'
+```
+
+or create `.goscript` files that you can run using a “shebang” line:
+
+```sh
+#!/tmp/goscript.sh
+script.Stdin().Column(1).Freq().First(10).Stdout()
+```
+
+# Documentation
+
+See [pkg.go.dev](https://pkg.go.dev/github.com/bitfield/script) for the full documentation, or read on for a summary.
+
+[](https://bitfieldconsulting.com/books/tools)
+
+The `script` package originated as an exercise in my book [The Power of Go: Tools](https://bitfieldconsulting.com/books/tools):
+
+> *Not all software engineering is about writing applications. Developers also need tooling: programs and services to automate everyday tasks like configuring servers and containers, running builds and tests, deploying their applications, and so on. Why shouldn't we be able to use Go for that purpose, too?*
+>
+> *`script` is designed to make it easy to write Go programs that chain together operations into a pipeline, in the same way that shell scripts do, but with the robust type checking and error handling of a real programming language. You can use `script` to construct the sort of simple one‐off pipelines that would otherwise require the shell, or special‐purpose tools.*

+> *So, when plain Go doesn’t provide a convenient way to solve a problem, you yourself can use it to implement a domain-specific “language” that does. In this case, we used Go to provide the language of Unix‐style pipelines. But we could have chosen any architecture we wanted to suit the problem. If Go doesn’t already provide the tool you need, use Go to build that tool, then use it.*\

+
+| Filter | Results |
+| -------- | ------------- |
+| [`Basename`](https://pkg.go.dev/github.com/bitfield/script#Pipe.Basename) | removes leading path components from each line, leaving only the filename |

+| [`FilterScan`](https://pkg.go.dev/github.com/bitfield/script#Pipe.FilterScan) | user-supplied function filtering each line to a writer |
+| [`First`](https://pkg.go.dev/github.com/bitfield/script#Pipe.First) | first N lines of input |
+| [`Freq`](https://pkg.go.dev/github.com/bitfield/script#Pipe.Freq) | frequency count of unique input lines, most frequent first |
+| [`Get`](https://pkg.go.dev/github.com/bitfield/script#Pipe.Get) | response to HTTP GET on supplied URL |
+| [`HashSums`](https://pkg.go.dev/github.com/bitfield/script#Pipe.HashSums) | hashes of each listed file |
+| [`Join`](https://pkg.go.dev/github.com/bitfield/script#Pipe.Join) | replace all newlines with spaces |
+| [`JQ`](https://pkg.go.dev/github.com/bitfield/script#Pipe.JQ) | result of `jq` query |
+| [`Last`](https://pkg.go.dev/github.com/bitfield/script#Pipe.Last) | last N lines of input|
+| [`Match`](https://pkg.go.dev/github.com/bitfield/script#Pipe.Match) | lines matching given string |
+| [`MatchRegexp`](https://pkg.go.dev/github.com/bitfield/script#Pipe.MatchRegexp) | lines matching given regexp |
+| [`Post`](https://pkg.go.dev/github.com/bitfield/script#Pipe.Post) | response to HTTP POST on supplied URL |
+| [`Reject`](https://pkg.go.dev/github.com/bitfield/script#Pipe.Reject) | lines not matching given string |

+| [`Tee`](https://pkg.go.dev/github.com/bitfield/script#Pipe.Tee) | input copied to supplied writers |
+
+Note that filters run concurrently, rather than producing nothing until each stage has fully read its input. This is convenient for executing long-running commands, for example. If you do need to wait for the pipeline to complete, call [`Wait`](https://pkg.go.dev/github.com/bitfield/script#Pipe.Wait).
+
+## Sinks
+
+Sinks are methods that return some data from a pipe, ending the pipeline and extracting its full contents in a specified way:
+
+| Sink | Destination | Results |
+| ---- | ----------- | ------- |
+| [`AppendFile`](https://pkg.go.dev/github.com/bitfield/script#Pipe.AppendFile) | appended to file, creating if it doesn't exist | bytes written, error |
+| [`Bytes`](https://pkg.go.dev/github.com/bitfield/script#Pipe.Bytes) | | data as `[]byte`, error

+
+## Examples
+
+```Go
+package main
+
+import (
+ "github.com/briandowns/spinner"
+ "time"
+)
+
+func main() {
+ s := spinner.New(spinner.CharSets[9], 100*time.Millisecond) // Build our new spinner
+ s.Start() // Start the spinner
+ time.Sleep(4 * time.Second) // Run for some time to simulate work
+ s.Stop()
+}
+```
+
+## Update the character set and restart the spinner
+
+```Go
+s.UpdateCharSet(spinner.CharSets[1]) // Update spinner to use a different character set
+s.Restart() // Restart the spinner
+time.Sleep(4 * time.Second)
+s.Stop()
+```
+
+## Update spin speed and restart the spinner
+
+```Go
+s.UpdateSpeed(200 * time.Millisecond) // Update the speed the spinner spins at
+s.Restart()
+time.Sleep(4 * time.Second)
+s.Stop()
+```
+
+## Reverse the direction of the spinner
+
+```Go
+s.Reverse() // Reverse the direction the spinner is spinning
+s.Restart()
+time.Sleep(4 * time.Second)
+s.Stop()
+```
+
+## Provide your own spinner
+
+(or send me an issue or pull request to add to the project)
+
+```Go
+someSet := []string{"+", "-"}
+s := spinner.New(someSet, 100*time.Millisecond)
+```
+
+## Prefix or append text to the spinner
+
+```Go
+s.Prefix = "prefixed text: " // Prefix text before the spinner
+s.Suffix = " :appended text" // Append text after the spinner
+```
+
+## Set or change the color of the spinner. Default color is white. The spinner will need to be restarted to pick up the change.
+
+```Go
+s.Color("red") // Set the spinner color to red
+```
+
+You can specify both the background and foreground color, as well as additional attributes such as `bold` or `underline`.
+
+```Go
+s.Color("red", "bold") // Set the spinner color to a bold red
+```
+
+To set the background to black, the foreground to a bold red:
+
+```Go
+s.Color("bgBlack", "bold", "fgRed")
+```
+
+Below is the full color and attribute list:
+
+```Go
+// default colors
+red
+black
+green
+yellow
+blue
+magenta
+cyan
+white
+
+// attributes
+reset
+bold
+faint
+italic
+underline
+blinkslow
+blinkrapid
+reversevideo
+concealed
+crossedout
+
+// foreground text
+fgBlack
+fgRed
+fgGreen
+fgYellow
+fgBlue
+fgMagenta
+fgCyan
+fgWhite
+
+// foreground Hi-Intensity text
+fgHiBlack
+fgHiRed
+fgHiGreen
+fgHiYellow
+fgHiBlue
+fgHiMagenta
+fgHiCyan
+fgHiWhite
+
+// background text
+bgBlack
+bgRed
+bgGreen
+bgYellow
+bgBlue
+bgMagenta
+bgCyan
+bgWhite
+
+// background Hi-Intensity text
+bgHiBlack
+bgHiRed
+bgHiGreen
+bgHiYellow
+bgHiBlue
+bgHiMagenta
+bgHiCyan
+bgHiWhite
+```
+
+## Generate a sequence of numbers
+
+```Go
+setOfDigits := spinner.GenerateNumberSequence(25) // Generate a 25 digit string of numbers
+s := spinner.New(setOfDigits, 100*time.Millisecond)
+```
+
+## Get spinner status
+
+```Go
+fmt.Println(s.Active())
+```
+
+## Unix pipe and redirect
+
+Feature suggested and write up by [dekz](https://github.com/dekz)
+
+Setting the Spinner Writer to Stderr helps show progress to the user, with the enhancement to chain, pipe or redirect the output.
+
+This is the preferred method of setting a Writer at this time.
+
+```go
+s := spinner.New(spinner.CharSets[11], 100*time.Millisecond, spinner.WithWriter(os.Stderr))
+s.Suffix = " Encrypting data..."
+s.Start()
+// Encrypt the data into ciphertext
+fmt.Println(os.Stdout, ciphertext)
+```
+
+```sh
+> myprog encrypt "Secret text" > encrypted.txt
+⣯ Encrypting data...
+```
+
+```sh
+> cat encrypted.txt
+1243hjkbas23i9ah27sj39jghv237n2oa93hg83
+```
+
+## Final String Output
+
+Add additional output when the spinner/indicator has completed. The "final" output string can be multi-lined and will be written to wherever the `io.Writer` has been configured for.
+
+```Go
+s := spinner.New(spinner.CharSets[9], 100*time.Millisecond)
+s.FinalMSG = "Complete!\nNew line!\nAnother one!\n"
+s.Start()
+time.Sleep(4 * time.Second)
+s.Stop()
+```
+
+Output
+```sh
+Complete!
+New line!
+Another one!
+```

+# Color [](https://godoc.org/github.com/fatih/color) [](https://travis-ci.org/fatih/color)
+
+
+
+Color lets you use colorized outputs in terms of [ANSI Escape
+Codes](http://en.wikipedia.org/wiki/ANSI_escape_code#Colors) in Go (Golang). It
+has support for Windows too! The API can be used in several ways, pick one that
+suits you.
+
+
+
+
+
+## Install
+
+```bash
+go get github.com/fatih/color
+```
+
+Note that the `vendor` folder is here for stability. Remove the folder if you
+already have the dependencies in your GOPATH.
+
+## Examples
+
+### Standard colors
+
+```go
+// Print with default helper functions
+color.Cyan("Prints text in cyan.")
+
+// A newline will be appended automatically
+color.Blue("Prints %s in blue.", "text")
+
+// These are using the default foreground colors
+color.Red("We have red")
+color.Magenta("And many others ..")
+
+```
+
+### Mix and reuse colors
+
+```go
+// Create a new color object
+c := color.New(color.FgCyan).Add(color.Underline)
+c.Println("Prints cyan text with an underline.")
+
+// Or just add them to New()
+d := color.New(color.FgCyan, color.Bold)
+d.Printf("This prints bold cyan %s\n", "too!.")
+
+// Mix up foreground and background colors, create new mixes!
+red := color.New(color.FgRed)
+
+boldRed := red.Add(color.Bold)
+boldRed.Println("This will print text in bold red.")
+
+whiteBackground := red.Add(color.BgWhite)
+whiteBackground.Println("Red text with white background.")
+```
+
+### Use your own output (io.Writer)
+
+```go
+// Use your own io.Writer output
+color.New(color.FgBlue).Fprintln(myWriter, "blue color!")
+
+blue := color.New(color.FgBlue)
+blue.Fprint(writer, "This will print text in blue.")
+```
+
+### Custom print functions (PrintFunc)
+
+```go
+// Create a custom print function for convenience
+red := color.New(color.FgRed).PrintfFunc()
+red("Warning")
+red("Error: %s", err)
+
+// Mix up multiple attributes
+notice := color.New(color.Bold, color.FgGreen).PrintlnFunc()
+notice("Don't forget this...")
+```
+
+### Custom fprint functions (FprintFunc)
+
+```go
+blue := color.New(FgBlue).FprintfFunc()
+blue(myWriter, "important notice: %s", stars)
+
+// Mix up with multiple attributes
+success := color.New(color.Bold, color.FgGreen).FprintlnFunc()
+success(myWriter, "Don't forget this...")
+```
+
+### Insert into noncolor strings (SprintFunc)
+
+```go
+// Create SprintXxx functions to mix strings with other non-colorized strings:
+yellow := color.New(color.FgYellow).SprintFunc()
+red := color.New(color.FgRed).SprintFunc()
+fmt.Printf("This is a %s and this is %s.\n", yellow("warning"), red("error"))
+
+info := color.New(color.FgWhite, color.BgGreen).SprintFunc()
+fmt.Printf("This %s rocks!\n", info("package"))
+
+// Use helper functions
+fmt.Println("This", color.RedString("warning"), "should be not neglected.")
+fmt.Printf("%v %v\n", color.GreenString("Info:"), "an important message.")
+
+// Windows supported too! Just don't forget to change the output to color.Output
+fmt.Fprintf(color.Output, "Windows support: %s", color.GreenString("PASS"))
+```
+
+### Plug into existing code
+
+```go
+// Use handy standard colors
+color.Set(color.FgYellow)
+
+fmt.Println("Existing text will now be in yellow")
+fmt.Printf("This one %s\n", "too")
+
+color.Unset() // Don't forget to unset
+
+// You can mix up parameters
+color.Set(color.FgMagenta, color.Bold)
+defer color.Unset() // Use it in your function
+
+fmt.Println("All text will now be bold magenta.")
+```
+
+### Disable/Enable color
+
+There might be a case where you want to explicitly disable/enable color output. the
+`go-isatty` package will automatically disable color output for non-tty output streams
+(for example if the output were piped directly to `less`)
+
+`Color` has support to disable/enable colors both globally and for single color
+definitions. For example suppose you have a CLI app and a `--no-color` bool flag. You
+can easily disable the color output with:
+
+```go
+
+var flagNoColor = flag.Bool("no-color", false, "Disable color output")
+
+if *flagNoColor {
+ color.NoColor = true // disables colorized output
+}
+```
+
+It also has support for single color definitions (local). You can
+disable/enable color output on the fly:
+
+```go
+c := color.New(color.FgCyan)
+c.Println("Prints cyan text")
+
+c.DisableColor()
+c.Println("This is printed without any color")
+
+c.EnableColor()
+c.Println("This prints again cyan...")
+```

+/*
+Package color is an ANSI color package to output colorized or SGR defined
+output to the standard output. The API can be used in several way, pick one
+that suits you.
+
+Use simple and default helper functions with predefined foreground colors:
+
+ color.Cyan("Prints text in cyan.")
+
+ // a newline will be appended automatically
+ color.Blue("Prints %s in blue.", "text")
+
+ // More default foreground colors..
+ color.Red("We have red")
+ color.Yellow("Yellow color too!")
+ color.Magenta("And many others ..")
+
+ // Hi-intensity colors
+ color.HiGreen("Bright green color.")
+ color.HiBlack("Bright black means gray..")
+ color.HiWhite("Shiny white color!")
+
+However there are times where custom color mixes are required. Below are some
+examples to create custom color objects and use the print functions of each
+separate color object.
+
+ // Create a new color object
+ c := color.New(color.FgCyan).Add(color.Underline)
+ c.Println("Prints cyan text with an underline.")
+
+ // Or just add them to New()
+ d := color.New(color.FgCyan, color.Bold)
+ d.Printf("This prints bold cyan %s\n", "too!.")
+
+
+ // Mix up foreground and background colors, create new mixes!
+ red := color.New(color.FgRed)
+
+ boldRed := red.Add(color.Bold)
+ boldRed.Println("This will print text in bold red.")
+
+ whiteBackground := red.Add(color.BgWhite)
+ whiteBackground.Println("Red text with White background.")
+
+ // Use your own io.Writer output
+ color.New(color.FgBlue).Fprintln(myWriter, "blue color!")
+
+ blue := color.New(color.FgBlue)
+ blue.Fprint(myWriter, "This will print text in blue.")
+
+You can create PrintXxx functions to simplify even more:
+
+ // Create a custom print function for convenient
+ red := color.New(color.FgRed).PrintfFunc()
+ red("warning")
+ red("error: %s", err)
+
+ // Mix up multiple attributes
+ notice := color.New(color.Bold, color.FgGreen).PrintlnFunc()
+ notice("don't forget this...")
+
+You can also FprintXxx functions to pass your own io.Writer:
+
+ blue := color.New(FgBlue).FprintfFunc()
+ blue(myWriter, "important notice: %s", stars)
+
+ // Mix up with multiple attributes
+ success := color.New(color.Bold, color.FgGreen).FprintlnFunc()
+ success(myWriter, don't forget this...")
+
+
+Or create SprintXxx functions to mix strings with other non-colorized strings:
+
+ yellow := New(FgYellow).SprintFunc()
+ red := New(FgRed).SprintFunc()
+
+ fmt.Printf("this is a %s and this is %s.\n", yellow("warning"), red("error"))
+
+ info := New(FgWhite, BgGreen).SprintFunc()
+ fmt.Printf("this %s rocks!\n", info("package"))
+
+Windows support is enabled by default. All Print functions work as intended.
+However only for color.SprintXXX functions, user should use fmt.FprintXXX and
+set the output to color.Output:
+
+ fmt.Fprintf(color.Output, "Windows support: %s", color.GreenString("PASS"))
+
+ info := New(FgWhite, BgGreen).SprintFunc()
+ fmt.Fprintf(color.Output, "this %s rocks!\n", info("package"))
+
+Using with existing code is possible. Just use the Set() method to set the
+standard output to the given parameters. That way a rewrite of an existing
+code is not required.
+
+ // Use handy standard colors.
+ color.Set(color.FgYellow)
+
+ fmt.Println("Existing text will be now in Yellow")
+ fmt.Printf("This one %s\n", "too")
+
+ color.Unset() // don't forget to unset
+
+ // You can mix up parameters
+ color.Set(color.FgMagenta, color.Bold)
+ defer color.Unset() // use it in your function
+
+ fmt.Println("All text will be now bold magenta.")
+
+There might be a case where you want to disable color output (for example to
+pipe the standard output of your app to somewhere else). `Color` has support to
+disable colors both globally and for single color definition. For example
+suppose you have a CLI app and a `--no-color` bool flag. You can easily disable
+the color output with:
+
+ var flagNoColor = flag.Bool("no-color", false, "Disable color output")
+
+ if *flagNoColor {
+ color.NoColor = true // disables colorized output
+ }
+
+It also has support for single color definitions (local). You can
+disable/enable color output on the fly:
+
+ c := color.New(color.FgCyan)
+ c.Println("Prints cyan text")
+
+ c.DisableColor()
+ c.Println("This is printed without any color")
+
+ c.EnableColor()
+ c.Println("This prints again cyan...")

-# Contributing
-
-## Issues
-
-* Request features and report bugs using the [GitHub Issue Tracker](https://github.com/fsnotify/fsnotify/issues).
-* Please indicate the platform you are using fsnotify on.
-* A code example to reproduce the problem is appreciated.
-
-## Pull Requests
-
-### Contributor License Agreement
-
-fsnotify is derived from code in the [golang.org/x/exp](https://godoc.org/golang.org/x/exp) package and it may be included [in the standard library](https://github.com/fsnotify/fsnotify/issues/1) in the future. Therefore fsnotify carries the same [LICENSE](https://github.com/fsnotify/fsnotify/blob/master/LICENSE) as Go. Contributors retain their copyright, so you need to fill out a short form before we can accept your contribution: [Google Individual Contributor License Agreement](https://developers.google.com/open-source/cla/individual).
-
-Please indicate that you have signed the CLA in your pull request.
-
-### How fsnotify is Developed
-
-* Development is done on feature branches.
-* Tests are run on BSD, Linux, macOS and Windows.
-* Pull requests are reviewed and [applied to master][am] using [hub][].
- * Maintainers may modify or squash commits rather than asking contributors to.
-* To issue a new release, the maintainers will:
- * Update the CHANGELOG
- * Tag a version, which will become available through gopkg.in.
-
-### How to Fork
-
-For smooth sailing, always use the original import path. Installing with `go get` makes this easy.
-
-1. Install from GitHub (`go get -u github.com/fsnotify/fsnotify`)
-2. Create your feature branch (`git checkout -b my-new-feature`)
-3. Ensure everything works and the tests pass (see below)
-4. Commit your changes (`git commit -am 'Add some feature'`)
-
-Contribute upstream:
-
-1. Fork fsnotify on GitHub
-2. Add your remote (`git remote add fork git@github.com:mycompany/repo.git`)
-3. Push to the branch (`git push fork my-new-feature`)
-4. Create a new Pull Request on GitHub
-
-This workflow is [thoroughly explained by Katrina Owen](https://splice.com/blog/contributing-open-source-git-repositories-go/).
-
-### Testing
-
-fsnotify uses build tags to compile different code on Linux, BSD, macOS, and Windows.
-
-Before doing a pull request, please do your best to test your changes on multiple platforms, and list which platforms you were able/unable to test on.
-
-To aid in cross-platform testing there is a Vagrantfile for Linux and BSD.
-
-* Install [Vagrant](http://www.vagrantup.com/) and [VirtualBox](https://www.virtualbox.org/)
-* Setup [Vagrant Gopher](https://github.com/nathany/vagrant-gopher) in your `src` folder.
-* Run `vagrant up` from the project folder. You can also setup just one box with `vagrant up linux` or `vagrant up bsd` (note: the BSD box doesn't support Windows hosts at this time, and NFS may prompt for your host OS password)
-* Once setup, you can run the test suite on a given OS with a single command `vagrant ssh linux -c 'cd fsnotify/fsnotify; go test'`.
-* When you're done, you will want to halt or destroy the Vagrant boxes.
-
-Notice: fsnotify file system events won't trigger in shared folders. The tests get around this limitation by using the /tmp directory.
-
-Right now there is no equivalent solution for Windows and macOS, but there are Windows VMs [freely available from Microsoft](http://www.modern.ie/en-us/virtualization-tools#downloads).
-
-### Maintainers
-
-Help maintaining fsnotify is welcome. To be a maintainer:
-
-* Submit a pull request and sign the CLA as above.
-* You must be able to run the test suite on Mac, Windows, Linux and BSD.
-
-To keep master clean, the fsnotify project uses the "apply mail" workflow outlined in Nathaniel Talbott's post ["Merge pull request" Considered Harmful][am]. This requires installing [hub][].
-
-All code changes should be internal pull requests.
-
-Releases are tagged using [Semantic Versioning](http://semver.org/).

-fsnotify utilizes [golang.org/x/sys](https://godoc.org/golang.org/x/sys) rather than `syscall` from the standard library. Ensure you have the latest version installed by running:
-
-```console
-go get -u golang.org/x/sys/...
-```
-
-Cross platform: Windows, Linux, BSD and macOS.

-
-## API stability
-
-fsnotify is a fork of [howeyc/fsnotify](https://godoc.org/github.com/howeyc/fsnotify) with a new API as of v1.0. The API is based on [this design document](http://goo.gl/MrYxyA).
-
-All [releases](https://github.com/fsnotify/fsnotify/releases) are tagged based on [Semantic Versioning](http://semver.org/). Further API changes are [planned](https://github.com/fsnotify/fsnotify/milestones), and will be tagged with a new major revision number.
-
-Go 1.6 supports dependencies located in the `vendor/` folder. Unless you are creating a library, it is recommended that you copy fsnotify into `vendor/github.com/fsnotify/fsnotify` within your project, and likewise for `golang.org/x/sys`.

-## FAQ
-
-**When a file is moved to another directory is it still being watched?**
-
-No (it shouldn't be, unless you are watching where it was moved to).
-
-**When I watch a directory, are all subdirectories watched as well?**
-
-No, you must add watches for any directory you want to watch (a recursive watcher is on the roadmap [#18][]).
-
-**Do I have to watch the Error and Event channels in a separate goroutine?**
-
-As of now, yes. Looking into making this single-thread friendly (see [howeyc #7][#7])
-
-**Why am I receiving multiple events for the same file on OS X?**
-
-Spotlight indexing on OS X can result in multiple events (see [howeyc #62][#62]). A temporary workaround is to add your folder(s) to the *Spotlight Privacy settings* until we have a native FSEvents implementation (see [#11][]).
-
-**How many files can be watched at once?**
-
-There are OS-specific limits as to how many watches can be created:
-* Linux: /proc/sys/fs/inotify/max_user_watches contains the limit, reaching this limit results in a "no space left on device" error.
-* BSD / OSX: sysctl variables "kern.maxfiles" and "kern.maxfilesperproc", reaching these limits results in a "too many open files" error.

-GopherJS - A compiler from Go to JavaScript
--------------------------------------------
-
-[](https://godoc.org/github.com/gopherjs/gopherjs/js)
-[](https://sourcegraph.com/github.com/gopherjs/gopherjs?badge)
-[](https://circleci.com/gh/gopherjs/gopherjs)
-
-GopherJS compiles Go code ([golang.org](https://golang.org/)) to pure JavaScript code. Its main purpose is to give you the opportunity to write front-end code in Go which will still run in all browsers.
-
-### Playground
-Give GopherJS a try on the [GopherJS Playground](http://gopherjs.github.io/playground/).
-
-### What is supported?
-Nearly everything, including Goroutines ([compatibility table](https://github.com/gopherjs/gopherjs/blob/master/doc/packages.md)). Performance is quite good in most cases, see [HTML5 game engine benchmark](https://ajhager.github.io/engi/demos/botmark.html). Cgo is not supported.
-
-### Installation and Usage
-Get or update GopherJS and dependencies with:
-
-```
-go get -u github.com/gopherjs/gopherjs
-```
-
-Now you can use `gopherjs build [package]`, `gopherjs build [files]` or `gopherjs install [package]` which behave similar to the `go` tool. For `main` packages, these commands create a `.js` file and `.js.map` source map in the current directory or in `$GOPATH/bin`. The generated JavaScript file can be used as usual in a website. Use `gopherjs help [command]` to get a list of possible command line flags, e.g. for minification and automatically watching for changes.
-
-`gopherjs` uses your platform's default `GOOS` value when generating code. Supported `GOOS` values are: `linux`, `darwin`. If you're on a different platform (e.g., Windows or FreeBSD), you'll need to set the `GOOS` environment variable to a supported value. For example, `GOOS=linux gopherjs build [package]`.
-
-*Note: GopherJS will try to write compiled object files of the core packages to your $GOROOT/pkg directory. If that fails, it will fall back to $GOPATH/pkg.*
-
-#### gopherjs run, gopherjs test
-
-If you want to use `gopherjs run` or `gopherjs test` to run the generated code locally, install Node.js 10.0.0 (or newer), and the `source-map-support` module:
-
-```
-npm install --global source-map-support
-```
-
-On supported `GOOS` platforms, it's possible to make system calls (file system access, etc.) available. See [doc/syscalls.md](https://github.com/gopherjs/gopherjs/blob/master/doc/syscalls.md) for instructions on how to do so.
-
-#### gopherjs serve
-
-`gopherjs serve` is a useful command you can use during development. It will start an HTTP server serving on ":8080" by default, then dynamically compile your Go packages with GopherJS and serve them.
-
-For example, navigating to `http://localhost:8080/example.com/user/project/` should compile and run the Go package `example.com/user/project`. The generated JavaScript output will be served at `http://localhost:8080/example.com/user/project/project.js` (the .js file name will be equal to the base directory name). If the directory contains `index.html` it will be served, otherwise a minimal `index.html` that includes `` will be provided, causing the JavaScript to be executed. All other static files will be served too.
-
-Refreshing in the browser will rebuild the served files if needed. Compilation errors will be displayed in terminal, and in browser console. Additionally, it will serve $GOROOT and $GOPATH for sourcemaps.
-
-If you include an argument, it will be the root from which everything is served. For example, if you run `gopherjs serve github.com/user/project` then the generated JavaScript for the package github.com/user/project/mypkg will be served at http://localhost:8080/mypkg/mypkg.js.
-
-### Performance Tips
-
-- Use the `-m` command line flag to generate minified code.
-- Apply gzip compression (https://en.wikipedia.org/wiki/HTTP_compression).
-- Use `int` instead of `(u)int8/16/32/64`.
-- Use `float64` instead of `float32`.

-
-### Getting started
-
-#### Interacting with the DOM
-The package `github.com/gopherjs/gopherjs/js` (see [documentation](https://godoc.org/github.com/gopherjs/gopherjs/js)) provides functions for interacting with native JavaScript APIs. For example the line
-
-```js
-document.write("Hello world!");
-```
-
-would look like this in Go:
-
-```go
-js.Global.Get("document").Call("write", "Hello world!")
-```
-
-You may also want use the [DOM bindings](http://dominik.honnef.co/go/js/dom), the [jQuery bindings](https://github.com/gopherjs/jquery) (see [TodoMVC Example](https://github.com/gopherjs/todomvc)) or the [AngularJS bindings](https://github.com/wvell/go-angularjs). Those are some of the [bindings to JavaScript APIs and libraries](https://github.com/gopherjs/gopherjs/wiki/bindings) by community members.
-
-#### Providing library functions for use in other JavaScript code
-Set a global variable to a map that contains the functions:
-
-```go
-package main
-
-import "github.com/gopherjs/gopherjs/js"
-
-func main() {
- js.Global.Set("pet", map[string]interface{}{
- "New": New,
- })
-}
-
-type Pet struct {
- name string
-}
-
-func New(name string) *js.Object {
- return js.MakeWrapper(&Pet{name})
-}
-
-func (p *Pet) Name() string {
- return p.name
-}
-
-func (p *Pet) SetName(name string) {
- p.name = name
-}
-```
-
-For more details see [Jason Stone's blog post](http://legacytotheedge.blogspot.de/2014/03/gopherjs-go-to-javascript-transpiler.html) about GopherJS.
-
-### Architecture
-
-#### General
-GopherJS emulates a 32-bit environment. This means that `int`, `uint` and `uintptr` have a precision of 32 bits. However, the explicit 64-bit integer types `int64` and `uint64` are supported. The `GOARCH` value of GopherJS is "js". You may use it as a build constraint: `// +build js`.
-
-#### Application Lifecycle
-
-The `main` function is executed as usual after all `init` functions have run. JavaScript callbacks can also invoke Go functions, even after the `main` function has exited. Therefore the end of the `main` function should not be regarded as the end of the application and does not end the execution of other goroutines.
-
-In the browser, calling `os.Exit` (e.g. indirectly by `log.Fatal`) also does not terminate the execution of the program. For convenience, it calls `runtime.Goexit` to immediately terminate the calling goroutine.
-
-#### Goroutines
-Goroutines are fully supported by GopherJS. The only restriction is that you need to start a new goroutine if you want to use blocking code called from external JavaScript:
-
-```go
-js.Global.Get("myButton").Call("addEventListener", "click", func() {
- go func() {
- [...]
- someBlockingFunction()
- [...]
- }()
-})
-```
-
-How it works:
-
-JavaScript has no concept of concurrency (except web workers, but those are too strictly separated to be used for goroutines). Because of that, instructions in JavaScript are never blocking. A blocking call would effectively freeze the responsiveness of your web page, so calls with callback arguments are used instead.
-
-GopherJS does some heavy lifting to work around this restriction: Whenever an instruction is blocking (e.g. communicating with a channel that isn't ready), the whole stack will unwind (= all functions return) and the goroutine will be put to sleep. Then another goroutine which is ready to resume gets picked and its stack with all local variables will be restored.
-
-### GopherJS Development
-If you're looking to make changes to the GopherJS compiler, see [Developer Guidelines](https://github.com/gopherjs/gopherjs/wiki/Developer-Guidelines) for additional developer information.

+* fix priority bug of declared and builtin functions (`def empty: .; null | select(.)`)
+* fix string indexing by index out of bounds to emit `null` (`"abc" | .[3]`)
+* fix array binding pattern not to match against strings (`"abc" as [$a] ?// $a | $a`)
+* fix `sub` and `gsub` functions to emit results in the same order of jq
+* fix `fromjson` to keep integer precision (`"10000000000000000" | fromjson + 1`)

+### Pure Go implementation of [jq](https://github.com/jqlang/jq)
+This is an implementation of jq command written in Go language.
+You can also embed gojq as a library to your Go products.
+
+## Usage
+```sh
+ $ echo '{"foo": 128}' | gojq '.foo'
+128
+ $ echo '{"a": {"b": 42}}' | gojq '.a.b'
+42
+ $ echo '{"id": "sample", "10": {"b": 42}}' | gojq '{(.id): .["10"].b}'
+{
+ "sample": 42
+}
+ $ echo '[{"id":1},{"id":2},{"id":3}]' | gojq '.[] | .id'
+1
+2
+3
+ $ echo '{"a":1,"b":2}' | gojq '.a += 1 | .b *= 2'
+{
+ "a": 2,
+ "b": 4
+}
+ $ echo '{"a":1} [2] 3' | gojq '. as {$a} ?// [$a] ?// $a | $a'
+1
+2
+3
+ $ echo '{"foo": 4722366482869645213696}' | gojq .foo
+4722366482869645213696 # keeps the precision of large numbers
+ $ gojq -n 'def fact($n): if $n < 1 then 1 else $n * fact($n - 1) end; fact(50)'
+30414093201713378043612608166064768844377641568960512000000000000 # arbitrary-precision integer calculation
+```
+
+Nice error messages.
+```sh
+ $ echo '[1,2,3]' | gojq '.foo & .bar'
+gojq: invalid query: .foo & .bar
+ .foo & .bar
+ ^ unexpected token "&"
+ $ echo '{"foo": { bar: [] } }' | gojq '.'
+gojq: invalid json:
+ {"foo": { bar: [] } }
+ ^ invalid character 'b' looking for beginning of object key string
+```

+
+## Difference to jq
+- gojq is purely implemented with Go language and is completely portable. jq depends on the C standard library so the availability of math functions depends on the library. jq also depends on the regular expression library and it makes build scripts complex.
+- gojq implements nice error messages for invalid query and JSON input. The error message of jq is sometimes difficult to tell where to fix the query.
+- gojq does not keep the order of object keys. I understand this might cause problems for some scripts but basically, we should not rely on the order of object keys. Due to this limitation, gojq does not have `keys_unsorted` function and `--sort-keys` (`-S`) option. I would implement when ordered map is implemented in the standard library of Go but I'm less motivated.
+- gojq supports arbitrary-precision integer calculation while jq does not; jq loses the precision of large integers when calculation is involved. Note that even with gojq, all mathematical functions, including `floor` and `round`, convert integers to floating-point numbers; only addition, subtraction, multiplication, modulo, and division operators (when divisible) keep the integer precision. To calculate floor division of integers without losing the precision, use `def idivide($n): (. - . % $n) / $n;`. To round down floating-point numbers to integers, use `def ifloor: floor | tostring | tonumber;`, but note that this function does not work with large floating-point numbers and also loses the precision of large integers.
+- gojq fixes various bugs of jq. gojq correctly deletes elements of arrays by `|= empty` ([jq#2051](https://github.com/jqlang/jq/issues/2051)). gojq fixes `try`/`catch` handling ([jq#1859](https://github.com/jqlang/jq/issues/1859), [jq#1885](https://github.com/jqlang/jq/issues/1885), [jq#2140](https://github.com/jqlang/jq/issues/2140)). gojq fixes `nth/2` to output nothing when the count is equal to or larger than the stream size ([jq#1867](https://github.com/jqlang/jq/issues/1867)). gojq consistently counts by characters (not by bytes) in `index`, `rindex`, and `indices` functions; `"１２３４５" | .[index("３"):]` results in `"３４５"` ([jq#1430](https://github.com/jqlang/jq/issues/1430), [jq#1624](https://github.com/jqlang/jq/issues/1624)). gojq handles overlapping occurrence differently in `rindex` and `indices`; `"ababa" | [rindex("aba"), indices("aba")]` results in `[2,[0,2]]` ([jq#2433](https://github.com/jqlang/jq/issues/2433)). gojq supports string indexing; `"abcde"[2]` ([jq#1520](https://github.com/jqlang/jq/issues/1520)). gojq accepts indexing query `.e0` ([jq#1526](https://github.com/jqlang/jq/issues/1526), [jq#1651](https://github.com/jqlang/jq/issues/1651)), and allows `gsub` to handle patterns including `"^"` ([jq#2148](https://github.com/jqlang/jq/issues/2148)). gojq improves variable lexer to allow using keywords for variable names, especially in binding patterns, also disallows spaces after `$` ([jq#526](https://github.com/jqlang/jq/issues/526)). gojq fixes handling files with no newline characters at the end ([jq#2374](https://github.com/jqlang/jq/issues/2374)).
+- gojq truncates down floating-point numbers on indexing (`[0] | .[0.5]` results in `0` not `null`), and slicing (`[0,1,2] | .[0.5:1.5]` results in `[0]` not `[0,1]`). gojq parses unary operators with higher precedence than variable binding (`[-1 as $x | 1,$x]` results in `[1,-1]` not `[-1,-1]`). gojq implements `@uri` to escape all the reserved characters defined in RFC 3986, Sec. 2.2 ([jq#1506](https://github.com/jqlang/jq/issues/1506)), and fixes `@base64d` to allow binary string as the decoded string ([jq#1931](https://github.com/jqlang/jq/issues/1931)). gojq improves time formatting and parsing; deals with `%f` in `strftime` and `strptime` ([jq#1409](https://github.com/jqlang/jq/issues/1409)), parses timezone offsets with `fromdate` and `fromdateiso8601` ([jq#1053](https://github.com/jqlang/jq/issues/1053)), supports timezone name/offset with `%Z`/`%z` in `strptime` ([jq#929](https://github.com/jqlang/jq/issues/929), [jq#2195](https://github.com/jqlang/jq/issues/2195)), and looks up correct timezone during daylight saving time on formatting with `%Z` ([jq#1912](https://github.com/jqlang/jq/issues/1912)). gojq supports nanoseconds in date and time functions.
+- gojq does not support some functions intentionally; `get_jq_origin`, `get_prog_origin`, `get_search_list` (unstable, not listed in jq document), `input_line_number`, `$__loc__` (performance issue), `recurse_down` (deprecated in jq). gojq does not support some flags; `--ascii-output, -a` (performance issue), `--seq` (not used commonly), `--sort-keys, -S` (sorts by default because `map[string]any` does not keep the order), `--unbuffered` (unbuffered by default). gojq does not parse JSON extensions supported by jq; `NaN`, `Infinity`, and `[000]`. gojq normalizes floating-point numbers to fit to double-precision floating-point numbers. gojq does not support or behaves differently with some regular expression metacharacters and flags (regular expression engine differences). gojq does not support BOM (`encoding/json` does not support this). gojq disallows using keywords for function names (`def true: .; true` is a confusing query), and module name prefixes in function declarations (using module prefixes like `def m::f: .;` is undocumented).
+- gojq supports reading from YAML input (`--yaml-input`) while jq does not. gojq also supports YAML output (`--yaml-output`). gojq supports a few filters missing in jq; `scan/2` ([jq#2207](https://github.com/jqlang/jq/pull/2207)), and `@urid` format string ([jq#2261](https://github.com/jqlang/jq/issues/2261)).
+
+### Color configuration
+The gojq command automatically disables coloring output when the output is not a tty.
+To force coloring output, specify `--color-output` (`-C`) option.
+When [`NO_COLOR` environment variable](https://no-color.org/) is present or `--monochrome-output` (`-M`) option is specified, gojq disables coloring output.
+
+Use `GOJQ_COLORS` environment variable to configure individual colors.
+The variable is a colon-separated list of ANSI escape sequences of `null`, `false`, `true`, numbers, strings, object keys, arrays, and objects.
+The default configuration is `90:33:33:36:32:34;1`.
+
+## Usage as a library
+You can use the gojq parser and interpreter from your Go products.
+
+```go
+package main
+
+import (
+ "fmt"
+ "log"
+
+ "github.com/itchyny/gojq"
+)
+
+func main() {
+ query, err := gojq.Parse(".foo | ..")
+ if err != nil {
+ log.Fatalln(err)
+ }
+ input := map[string]any{"foo": []any{1, 2, 3}}
+ iter := query.Run(input) // or query.RunWithContext
+ for {
+ v, ok := iter.Next()
+ if !ok {
+ break
+ }
+ if err, ok := v.(error); ok {
+ log.Fatalln(err)
+ }
+ fmt.Printf("%#v\n", v)
+ }
+}
+```
+
+- Firstly, use [`gojq.Parse(string) (*Query, error)`](https://pkg.go.dev/github.com/itchyny/gojq#Parse) to get the query from a string.
+- Secondly, get the result iterator
+ - using [`query.Run`](https://pkg.go.dev/github.com/itchyny/gojq#Query.Run) or [`query.RunWithContext`](https://pkg.go.dev/github.com/itchyny/gojq#Query.RunWithContext)
+ - or alternatively, compile the query using [`gojq.Compile`](https://pkg.go.dev/github.com/itchyny/gojq#Compile) and then [`code.Run`](https://pkg.go.dev/github.com/itchyny/gojq#Code.Run) or [`code.RunWithContext`](https://pkg.go.dev/github.com/itchyny/gojq#Code.RunWithContext). You can reuse the `*Code` against multiple inputs to avoid compilation of the same query. But for arguments of `code.Run`, do not give values sharing same data between multiple calls.
+ - In either case, you cannot use custom type values as the query input. The type should be `[]any` for an array and `map[string]any` for a map (just like decoded to an `any` using the [encoding/json](https://golang.org/pkg/encoding/json/) package). You can't use `[]int` or `map[string]string`, for example. If you want to query your custom struct, marshal to JSON, unmarshal to `any` and use it as the query input.
+- Thirdly, iterate through the results using [`iter.Next() (any, bool)`](https://pkg.go.dev/github.com/itchyny/gojq#Iter). The iterator can emit an error so make sure to handle it. The method returns `true` with results, and `false` when the iterator terminates.
+ - The return type is not `(any, error)` because iterators can emit multiple errors and you can continue after an error. It is difficult for the iterator to tell the termination in this situation.
+ - Note that the result iterator may emit infinite number of values; `repeat(0)` and `range(infinite)`. It may stuck with no output value; `def f: f; f`. Use `RunWithContext` when you want to limit the execution time.
+
+[`gojq.Compile`](https://pkg.go.dev/github.com/itchyny/gojq#Compile) allows to configure the following compiler options.
+
+- [`gojq.WithModuleLoader`](https://pkg.go.dev/github.com/itchyny/gojq#WithModuleLoader) allows to load modules. By default, the module feature is disabled. If you want to load modules from the file system, use [`gojq.NewModuleLoader`](https://pkg.go.dev/github.com/itchyny/gojq#NewModuleLoader).
+- [`gojq.WithEnvironLoader`](https://pkg.go.dev/github.com/itchyny/gojq#WithEnvironLoader) allows to configure the environment variables referenced by `env` and `$ENV`. By default, OS environment variables are not accessible due to security reasons. You can use `gojq.WithEnvironLoader(os.Environ)` if you want.
+- [`gojq.WithVariables`](https://pkg.go.dev/github.com/itchyny/gojq#WithVariables) allows to configure the variables which can be used in the query. Pass the values of the variables to [`code.Run`](https://pkg.go.dev/github.com/itchyny/gojq#Code.Run) in the same order.
+- [`gojq.WithFunction`](https://pkg.go.dev/github.com/itchyny/gojq#WithFunction) allows to add a custom internal function. An internal function can return a single value (which can be an error) each invocation. To add a jq function (which may include a comma operator to emit multiple values, `empty` function, accept a filter for its argument, or call another built-in function), use `LoadInitModules` of the module loader.
+- [`gojq.WithIterFunction`](https://pkg.go.dev/github.com/itchyny/gojq#WithIterFunction) allows to add a custom iterator function. An iterator function returns an iterator to emit multiple values. You cannot define both iterator and non-iterator functions of the same name (with possibly different arities). You can use [`gojq.NewIter`](https://pkg.go.dev/github.com/itchyny/gojq#NewIter) to convert values or an error to a [`gojq.Iter`](https://pkg.go.dev/github.com/itchyny/gojq#Iter).
+- [`gojq.WithInputIter`](https://pkg.go.dev/github.com/itchyny/gojq#WithInputIter) allows to use `input` and `inputs` functions. By default, these functions are disabled.

+### Efficient time formatting library (strftime, strptime) for Golang
+This is a Go language package for formatting and parsing date time strings.
+
+```go
+package main
+
+import (
+ "fmt"
+ "log"
+
+ "github.com/itchyny/timefmt-go"
+)
+
+func main() {
+ t, err := timefmt.Parse("2020/07/24 09:07:29", "%Y/%m/%d %H:%M:%S")
+ if err != nil {
+ log.Fatal(err)
+ }
+ fmt.Println(t) // 2020-07-24 09:07:29 +0000 UTC
+
+ str := timefmt.Format(t, "%Y/%m/%d %H:%M:%S")
+ fmt.Println(str) // 2020/07/24 09:07:29
+
+ str = timefmt.Format(t, "%a, %d %b %Y %T %z")
+ fmt.Println(str) // Fri, 24 Jul 2020 09:07:29 +0000
+}
+```
+
+Please refer to [`man 3 strftime`](https://linux.die.net/man/3/strftime) and
+[`man 3 strptime`](https://linux.die.net/man/3/strptime) for formatters.
+As an extension, `%f` directive is supported for zero-padded microseconds, which originates from Python.
+Note that `E` and `O` modifier characters are not supported.
+
+## Comparison to other libraries
+- This library
+ - provides both formatting and parsing functions in pure Go language,
+ - depends only on the Go standard libraries not to grow up dependency.
+- `Format` (`strftime`) implements glibc extensions including
+ - width specifier like `%6Y %10B %4Z` (limited to 1024 bytes),
+ - omitting padding modifier like `%-y-%-m-%-d`,
+ - space padding modifier like `%_y-%_m-%_d`,
+ - upper case modifier like `%^a %^b`,
+ - swapping case modifier like `%#Z`,
+ - time zone offset modifier like `%:z %::z %:::z`,
+ - and its performance is very good.
+- `AppendFormat` is provided for reducing allocations.
+- `Parse` (`strptime`) allows to parse
+ - composed directives like `%F %T`,
+ - century years like `%C %y`,
+ - week names like `%A` `%a` (parsed results are discarded).
+- `ParseInLocation` is provided for configuring the default location.

+
+Colorable writer for windows.
+
+For example, most of logger packages doesn't show colors on windows. (I know we can do it with ansicon. But I don't want.)
+This package is possible to handle escape sequence for ansi color on windows.
+
+## Too Bad!
+
+
+
+
+## So Good!
+
+
+
+## Usage
+
+```go
+logrus.SetFormatter(&logrus.TextFormatter{ForceColors: true})
+logrus.SetOutput(colorable.NewColorableStdout())
+
+logrus.Info("succeeded")
+logrus.Warn("not correct")
+logrus.Error("something error")
+logrus.Fatal("panic")
+```
+
+You can compile above code on non-windows OSs.
+
+## Installation
+
+```
+$ go get github.com/mattn/go-colorable

+# Cobra Changelog
+
+## v1.1.3
+
+* **Fix:** release-branch.cobra1.1 only: Revert "Deprecate Go < 1.14" to maintain backward compatibility
+
+## v1.1.2
+
+### Notable Changes
+
+* Bump license year to 2021 in golden files (#1309) @Bowbaq
+* Enhance PowerShell completion with custom comp (#1208) @Luap99
+* Update gopkg.in/yaml.v2 to v2.4.0: The previous breaking change in yaml.v2 v2.3.0 has been reverted, see go-yaml/yaml#670

+* **Fix:** correct internal formatting for go-md2man v2 (which caused man page generation to be broken). See https://github.com/spf13/cobra/issues/1049 for context.
+
+## v1.1.0
+
+### Notable Changes

+## Cobra User Contract
+
+### Versioning
+Cobra will follow a steady release cadence. Non breaking changes will be released as minor versions quarterly. Patch bug releases are at the discretion of the maintainers. Users can expect security patch fixes to be released within relatively short order of a CVE becoming known. For more information on security patch fixes see the CVE section below. Releases will follow [Semantic Versioning](https://semver.org/). Users tracking the Master branch should expect unpredictable breaking changes as the project continues to move forward. For stability, it is highly recommended to use a release.
+
+### Backward Compatibility
+We will maintain two major releases in a moving window. The N-1 release will only receive bug fixes and security updates and will be dropped once N+1 is released.
+
+### Deprecation
+Deprecation of Go versions or dependent packages will only occur in major releases. To reduce the change of this taking users by surprise, any large deprecation will be preceded by an announcement in the [#cobra slack channel](https://gophers.slack.com/archives/CD3LP1199) and an Issue on Github.
+
+### CVE
+Maintainers will make every effort to release security patches in the case of a medium to high severity CVE directly impacting the library. The speed in which these patches reach a release is up to the discretion of the maintainers. A low severity CVE may be a lower priority than a high severity one.
+
+### Communication
+Cobra maintainers will use GitHub issues and the [#cobra slack channel](https://gophers.slack.com/archives/CD3LP1199) as the primary means of communication with the community. This is to foster open communication with all users and contributors.
+
+### Breaking Changes
+Breaking changes are generally allowed in the master branch, as this is the branch used to develop the next release of Cobra.
+
+There may be times, however, when master is closed for breaking changes. This is likely to happen as we near the release of a new version.
+
+Breaking changes are not allowed in release branches, as these represent minor versions that have already been released. These version have consumers who expect the APIs, behaviors, etc, to remain stable during the lifetime of the patch stream for the minor release.
+
+Examples of breaking changes include:
+- Removing or renaming exported constant, variable, type, or function.
+- Updating the version of critical libraries such as `spf13/pflag`, `spf13/viper` etc...
+ - Some version updates may be acceptable for picking up bug fixes, but maintainers must exercise caution when reviewing.
+
+There may, at times, need to be exceptions where breaking changes are allowed in release branches. These are at the discretion of the project's maintainers, and must be carefully considered before merging.
+
+### CI Testing
+Maintainers will ensure the Cobra test suite utilizes the current supported versions of Golang.
+
+### Disclaimer
+Changes to this document and the contents therein are at the discretion of the maintainers.
+None of the contents of this document are legally binding in any way to the maintainers or the users.

-# Getting Started
-
-While you are welcome to provide your own organization, typically a Cobra-based
-application will follow the following organizational structure:
-
-```
- ▾ appName/
- ▾ cmd/
- add.go
- your.go
- commands.go
- here.go
- main.go
-```
-
-In a Cobra app, typically the main.go file is very bare. It serves one purpose: initializing Cobra.
-
-```go
-package main
-
-import (
- "{pathToYourApp}/cmd"
-)
-
-func main() {
- cmd.Execute()
-}
-```
-
-## Using the Cobra Generator
-
-Cobra provides its own program that will create your application and add any
-commands you want. It's the easiest way to incorporate Cobra into your application.
-
-[Here](https://github.com/spf13/cobra/blob/master/cobra/README.md) you can find more information about it.
-
-## Using the Cobra Library
-
-To manually implement Cobra you need to create a bare main.go file and a rootCmd file.
-You will optionally provide additional commands as you see fit.
-
-### Create rootCmd
-
-Cobra doesn't require any special constructors. Simply create your commands.
-
-Ideally you place this in app/cmd/root.go:
-
-```go
-var rootCmd = &cobra.Command{
- Use: "hugo",
- Short: "Hugo is a very fast static site generator",
- Long: `A Fast and Flexible Static Site Generator built with
- love by spf13 and friends in Go.
- Complete documentation is available at http://hugo.spf13.com`,
- Run: func(cmd *cobra.Command, args []string) {
- // Do Stuff Here
- },
-}
-
-func Execute() {
- if err := rootCmd.Execute(); err != nil {
- fmt.Println(err)
- os.Exit(1)
- }
-}
-```
-
-You will additionally define flags and handle configuration in your init() function.
-
-For example cmd/root.go:
-
-```go
-import (
- "fmt"
- "os"
-
- homedir "github.com/mitchellh/go-homedir"
- "github.com/spf13/cobra"
- "github.com/spf13/viper"
-)
-
-func init() {
- cobra.OnInitialize(initConfig)
- rootCmd.PersistentFlags().StringVar(&cfgFile, "config", "", "config file (default is $HOME/.cobra.yaml)")
- rootCmd.PersistentFlags().StringVarP(&projectBase, "projectbase", "b", "", "base project directory eg. github.com/spf13/")
- rootCmd.PersistentFlags().StringP("author", "a", "YOUR NAME", "Author name for copyright attribution")
- rootCmd.PersistentFlags().StringVarP(&userLicense, "license", "l", "", "Name of license for the project (can provide `licensetext` in config)")
- rootCmd.PersistentFlags().Bool("viper", true, "Use Viper for configuration")
- viper.BindPFlag("author", rootCmd.PersistentFlags().Lookup("author"))
- viper.BindPFlag("projectbase", rootCmd.PersistentFlags().Lookup("projectbase"))
- viper.BindPFlag("useViper", rootCmd.PersistentFlags().Lookup("viper"))
- viper.SetDefault("author", "NAME HERE ")
- viper.SetDefault("license", "apache")
-}
-
-func initConfig() {
- // Don't forget to read config either from cfgFile or from home directory!
- if cfgFile != "" {
- // Use config file from the flag.
- viper.SetConfigFile(cfgFile)
- } else {
- // Find home directory.
- home, err := homedir.Dir()
- if err != nil {
- fmt.Println(err)
- os.Exit(1)
- }
-
- // Search config in home directory with name ".cobra" (without extension).
- viper.AddConfigPath(home)
- viper.SetConfigName(".cobra")
- }
-
- if err := viper.ReadInConfig(); err != nil {
- fmt.Println("Can't read config:", err)
- os.Exit(1)
- }
-}
-```
-
-### Create your main.go
-
-With the root command you need to have your main function execute it.
-Execute should be run on the root for clarity, though it can be called on any command.
-
-In a Cobra app, typically the main.go file is very bare. It serves, one purpose, to initialize Cobra.
-
-```go
-package main
-
-import (
- "{pathToYourApp}/cmd"
-)
-
-func main() {
- cmd.Execute()
-}
-```
-
-### Create additional commands
-
-Additional commands can be defined and typically are each given their own file
-inside of the cmd/ directory.
-
-If you wanted to create a version command you would create cmd/version.go and
-populate it with the following:
-
-```go
-package cmd
-
-import (
- "fmt"
-
- "github.com/spf13/cobra"
-)
-
-func init() {
- rootCmd.AddCommand(versionCmd)
-}
-
-var versionCmd = &cobra.Command{
- Use: "version",
- Short: "Print the version number of Hugo",
- Long: `All software has versions. This is Hugo's`,
- Run: func(cmd *cobra.Command, args []string) {
- fmt.Println("Hugo Static Site Generator v0.9 -- HEAD")
- },
-}
-```
-
-## Working with Flags
-
-Flags provide modifiers to control how the action command operates.
-
-### Assign flags to a command
-
-Since the flags are defined and used in different locations, we need to
-define a variable outside with the correct scope to assign the flag to
-work with.
-
-```go
-var Verbose bool
-var Source string
-```
-
-There are two different approaches to assign a flag.
-
-### Persistent Flags
-
-A flag can be 'persistent' meaning that this flag will be available to the
-command it's assigned to as well as every command under that command. For
-global flags, assign a flag as a persistent flag on the root.
-
-```go
-rootCmd.PersistentFlags().BoolVarP(&Verbose, "verbose", "v", false, "verbose output")
-```
-
-### Local Flags
-
-A flag can also be assigned locally which will only apply to that specific command.
-
-```go
-localCmd.Flags().StringVarP(&Source, "source", "s", "", "Source directory to read from")
-```
-
-### Local Flag on Parent Commands
-
-By default Cobra only parses local flags on the target command, any local flags on
-parent commands are ignored. By enabling `Command.TraverseChildren` Cobra will
-parse local flags on each command before executing the target command.
-
-```go
-command := cobra.Command{
- Use: "print [OPTIONS] [COMMANDS]",
- TraverseChildren: true,
-}
-```
-
-### Bind Flags with Config
-
-You can also bind your flags with [viper](https://github.com/spf13/viper):
-```go
-var author string
-
-func init() {
- rootCmd.PersistentFlags().StringVar(&author, "author", "YOUR NAME", "Author name for copyright attribution")
- viper.BindPFlag("author", rootCmd.PersistentFlags().Lookup("author"))
-}
-```
-
-In this example the persistent flag `author` is bound with `viper`.
-**Note**, that the variable `author` will not be set to the value from config,
-when the `--author` flag is not provided by user.
-
-More in [viper documentation](https://github.com/spf13/viper#working-with-flags).
-
-### Required flags
-
-Flags are optional by default. If instead you wish your command to report an error
-when a flag has not been set, mark it as required:
-```go
-rootCmd.Flags().StringVarP(&Region, "region", "r", "", "AWS region (required)")
-rootCmd.MarkFlagRequired("region")
-```
-
-## Positional and Custom Arguments
-
-Validation of positional arguments can be specified using the `Args` field
-of `Command`.
-
-The following validators are built in:
-
-- `NoArgs` - the command will report an error if there are any positional args.
-- `ArbitraryArgs` - the command will accept any args.
-- `OnlyValidArgs` - the command will report an error if there are any positional args that are not in the `ValidArgs` field of `Command`.
-- `MinimumNArgs(int)` - the command will report an error if there are not at least N positional args.
-- `MaximumNArgs(int)` - the command will report an error if there are more than N positional args.
-- `ExactArgs(int)` - the command will report an error if there are not exactly N positional args.
-- `ExactValidArgs(int)` - the command will report an error if there are not exactly N positional args OR if there are any positional args that are not in the `ValidArgs` field of `Command`
-- `RangeArgs(min, max)` - the command will report an error if the number of args is not between the minimum and maximum number of expected args.
-
-An example of setting the custom validator:
-
-```go
-var cmd = &cobra.Command{
- Short: "hello",
- Args: func(cmd *cobra.Command, args []string) error {
- if len(args) < 1 {
- return errors.New("requires a color argument")
- }
- if myapp.IsValidColor(args[0]) {
- return nil
- }
- return fmt.Errorf("invalid color specified: %s", args[0])
- },
- Run: func(cmd *cobra.Command, args []string) {
- fmt.Println("Hello, World!")
- },
-}
-```
-
-## Example
-
-In the example below, we have defined three commands. Two are at the top level
-and one (cmdTimes) is a child of one of the top commands. In this case the root
-is not executable meaning that a subcommand is required. This is accomplished
-by not providing a 'Run' for the 'rootCmd'.
-
-We have only defined one flag for a single command.
-
-More documentation about flags is available at https://github.com/spf13/pflag
-
-```go
-package main
-
-import (
- "fmt"
- "strings"
-
- "github.com/spf13/cobra"
-)
-
-func main() {
- var echoTimes int
-
- var cmdPrint = &cobra.Command{
- Use: "print [string to print]",
- Short: "Print anything to the screen",
- Long: `print is for printing anything back to the screen.
-For many years people have printed back to the screen.`,
- Args: cobra.MinimumNArgs(1),
- Run: func(cmd *cobra.Command, args []string) {
- fmt.Println("Print: " + strings.Join(args, " "))
- },
- }
-
- var cmdEcho = &cobra.Command{
- Use: "echo [string to echo]",
- Short: "Echo anything to the screen",
- Long: `echo is for echoing anything back.
-Echo works a lot like print, except it has a child command.`,
- Args: cobra.MinimumNArgs(1),
- Run: func(cmd *cobra.Command, args []string) {
- fmt.Println("Print: " + strings.Join(args, " "))
- },
- }
-
- var cmdTimes = &cobra.Command{
- Use: "times [string to echo]",
- Short: "Echo anything to the screen more times",
- Long: `echo things multiple times back to the user by providing
-a count and a string.`,
- Args: cobra.MinimumNArgs(1),
- Run: func(cmd *cobra.Command, args []string) {
- for i := 0; i < echoTimes; i++ {
- fmt.Println("Echo: " + strings.Join(args, " "))
- }
- },
- }
-
- cmdTimes.Flags().IntVarP(&echoTimes, "times", "t", 1, "times to echo the input")
-
- var rootCmd = &cobra.Command{Use: "app"}
- rootCmd.AddCommand(cmdPrint, cmdEcho)
- cmdEcho.AddCommand(cmdTimes)
- rootCmd.Execute()
-}
-```

-
-## Help Command
-
-Cobra automatically adds a help command to your application when you have subcommands.
-This will be called when a user runs 'app help'. Additionally, help will also
-support all other commands as input. Say, for instance, you have a command called
-'create' without any additional configuration; Cobra will work when 'app help
-create' is called. Every command will automatically have the '--help' flag added.
-
-### Example
-
-The following output is automatically generated by Cobra. Nothing beyond the
-command and flag definitions are needed.
-
- $ cobra help
-
- Cobra is a CLI library for Go that empowers applications.
- This application is a tool to generate the needed files
- to quickly create a Cobra application.
-
- Usage:
- cobra [command]
-
- Available Commands:
- add Add a command to a Cobra Application
- help Help about any command
- init Initialize a Cobra Application
-
- Flags:
- -a, --author string author name for copyright attribution (default "YOUR NAME")
- --config string config file (default is $HOME/.cobra.yaml)
- -h, --help help for cobra
- -l, --license string name of license for the project
- --viper use Viper for configuration (default true)
-
- Use "cobra [command] --help" for more information about a command.
-
-
-Help is just a command like any other. There is no special logic or behavior
-around it. In fact, you can provide your own if you want.
-
-### Defining your own help
-
-You can provide your own Help command or your own template for the default command to use
-with following functions:
-
-```go
-cmd.SetHelpCommand(cmd *Command)
-cmd.SetHelpFunc(f func(*Command, []string))
-cmd.SetHelpTemplate(s string)
-```
-
-The latter two will also apply to any children commands.
-
-## Usage Message
-
-When the user provides an invalid flag or invalid command, Cobra responds by
-showing the user the 'usage'.
-
-### Example
-You may recognize this from the help above. That's because the default help
-embeds the usage as part of its output.
-
- $ cobra --invalid
- Error: unknown flag: --invalid
- Usage:
- cobra [command]
-
- Available Commands:
- add Add a command to a Cobra Application
- help Help about any command
- init Initialize a Cobra Application
-
- Flags:
- -a, --author string author name for copyright attribution (default "YOUR NAME")
- --config string config file (default is $HOME/.cobra.yaml)
- -h, --help help for cobra
- -l, --license string name of license for the project
- --viper use Viper for configuration (default true)
-
- Use "cobra [command] --help" for more information about a command.
-
-### Defining your own usage
-You can provide your own usage function or template for Cobra to use.
-Like help, the function and template are overridable through public methods:
-
-```go
-cmd.SetUsageFunc(f func(*Command) error)
-cmd.SetUsageTemplate(s string)
-```
-
-## Version Flag
-
-Cobra adds a top-level '--version' flag if the Version field is set on the root command.
-Running an application with the '--version' flag will print the version to stdout using
-the version template. The template can be customized using the
-`cmd.SetVersionTemplate(s string)` function.
-
-## PreRun and PostRun Hooks
-
-It is possible to run functions before or after the main `Run` function of your command. The `PersistentPreRun` and `PreRun` functions will be executed before `Run`. `PersistentPostRun` and `PostRun` will be executed after `Run`. The `Persistent*Run` functions will be inherited by children if they do not declare their own. These functions are run in the following order:
-
-- `PersistentPreRun`
-- `PreRun`
-- `Run`
-- `PostRun`
-- `PersistentPostRun`
-
-An example of two commands which use all of these features is below. When the subcommand is executed, it will run the root command's `PersistentPreRun` but not the root command's `PersistentPostRun`:
-
-```go
-package main
-
-import (
- "fmt"
-
- "github.com/spf13/cobra"
-)
-
-func main() {
-
- var rootCmd = &cobra.Command{
- Use: "root [sub]",
- Short: "My root command",
- PersistentPreRun: func(cmd *cobra.Command, args []string) {
- fmt.Printf("Inside rootCmd PersistentPreRun with args: %v\n", args)
- },
- PreRun: func(cmd *cobra.Command, args []string) {
- fmt.Printf("Inside rootCmd PreRun with args: %v\n", args)
- },
- Run: func(cmd *cobra.Command, args []string) {
- fmt.Printf("Inside rootCmd Run with args: %v\n", args)
- },
- PostRun: func(cmd *cobra.Command, args []string) {
- fmt.Printf("Inside rootCmd PostRun with args: %v\n", args)
- },
- PersistentPostRun: func(cmd *cobra.Command, args []string) {
- fmt.Printf("Inside rootCmd PersistentPostRun with args: %v\n", args)
- },
- }
-
- var subCmd = &cobra.Command{
- Use: "sub [no options!]",
- Short: "My subcommand",
- PreRun: func(cmd *cobra.Command, args []string) {
- fmt.Printf("Inside subCmd PreRun with args: %v\n", args)
- },
- Run: func(cmd *cobra.Command, args []string) {
- fmt.Printf("Inside subCmd Run with args: %v\n", args)
- },
- PostRun: func(cmd *cobra.Command, args []string) {
- fmt.Printf("Inside subCmd PostRun with args: %v\n", args)
- },
- PersistentPostRun: func(cmd *cobra.Command, args []string) {
- fmt.Printf("Inside subCmd PersistentPostRun with args: %v\n", args)
- },
- }
-
- rootCmd.AddCommand(subCmd)
-
- rootCmd.SetArgs([]string{""})
- rootCmd.Execute()
- fmt.Println()
- rootCmd.SetArgs([]string{"sub", "arg1", "arg2"})
- rootCmd.Execute()
-}
-```
-
-Output:
-```
-Inside rootCmd PersistentPreRun with args: []
-Inside rootCmd PreRun with args: []
-Inside rootCmd Run with args: []
-Inside rootCmd PostRun with args: []
-Inside rootCmd PersistentPostRun with args: []
-
-Inside rootCmd PersistentPreRun with args: [arg1 arg2]
-Inside subCmd PreRun with args: [arg1 arg2]
-Inside subCmd Run with args: [arg1 arg2]
-Inside subCmd PostRun with args: [arg1 arg2]
-Inside subCmd PersistentPostRun with args: [arg1 arg2]
-```
-
-## Suggestions when "unknown command" happens
-
-Cobra will print automatic suggestions when "unknown command" errors happen. This allows Cobra to behave similarly to the `git` command when a typo happens. For example:
-
-```
-$ hugo srever
-Error: unknown command "srever" for "hugo"
-
-Did you mean this?
- server
-
-Run 'hugo --help' for usage.
-```
-
-Suggestions are automatic based on every subcommand registered and use an implementation of [Levenshtein distance](http://en.wikipedia.org/wiki/Levenshtein_distance). Every registered command that matches a minimum distance of 2 (ignoring case) will be displayed as a suggestion.
-
-If you need to disable suggestions or tweak the string distance in your command, use:
-
-```go
-command.DisableSuggestions = true
-```
-
-or
-
-```go
-command.SuggestionsMinimumDistance = 1
-```
-
-You can also explicitly set names for which a given command will be suggested using the `SuggestFor` attribute. This allows suggestions for strings that are not close in terms of string distance, but makes sense in your set of commands and for some which you don't want aliases. Example:
-
-```
-$ kubectl remove
-Error: unknown command "remove" for "kubectl"
-
-Did you mean this?
- delete
-
-Run 'kubectl help' for usage.
-```
-
-## Generating documentation for your command
-
-Cobra can generate documentation based on subcommands, flags, etc. in the following formats:
-
-- [Markdown](doc/md_docs.md)
-- [ReStructured Text](doc/rest_docs.md)
-- [Man Page](doc/man_docs.md)
-
-## Generating bash completions
-
-Cobra can generate a bash-completion file. If you add more information to your command, these completions can be amazingly powerful and flexible. Read more about it in [Bash Completions](bash_completions.md).
-
-## Generating zsh completions
-
-Cobra can generate zsh-completion file. Read more about it in
-[Zsh Completions](zsh_completions.md).

- rootCmd.GenBashCompletion(os.Stdout);
- },
-}
-```
-
-**Note:** The cobra generator may include messages printed to stdout for example if the config file is loaded, this will break the auto complete script
-
-
-## Example from kubectl
-
-Generating bash completions from a cobra command is incredibly easy. An actual program which does so for the kubernetes kubectl binary is as follows:
+## Bash legacy dynamic completions
-```go
-package main
-
-import (
- "io/ioutil"
- "os"
-
- "k8s.io/kubernetes/pkg/kubectl/cmd"
- "k8s.io/kubernetes/pkg/kubectl/cmd/util"
-)
+For backward compatibility, Cobra still supports its legacy dynamic completion solution (described below). Unlike the `ValidArgsFunction` solution, the legacy solution will only work for Bash shell-completion and not for other shells. This legacy solution can be used along-side `ValidArgsFunction` and `RegisterFlagCompletionFunc()`, as long as both solutions are not used for the same command. This provides a path to gradually migrate from the legacy solution to the new solution.
-func main() {
- kubectl := cmd.NewKubectlCommand(util.NewFactory(nil), os.Stdin, ioutil.Discard, ioutil.Discard)
- kubectl.GenBashCompletionFile("out.sh")
-}
-```
+**Note**: Cobra's default `completion` command uses bash completion V2. If you are currently using Cobra's legacy dynamic completion solution, you should not use the default `completion` command but continue using your own.
-`out.sh` will get you completions of subcommands and flags. Copy it to `/etc/bash_completion.d/` as described [here](https://debian-administration.org/article/316/An_introduction_to_bash_completion_part_1) and reset your terminal to use autocompletion. If you make additional annotations to your code, you can get even more intelligent and flexible behavior.
+The legacy solution allows you to inject bash functions into the bash completion script. Those bash functions are responsible for providing the completion choices for your own completions.
-## Creating your own custom functions

const (
@@ -111,108 +63,7 @@ Find more information at https://github.com/GoogleCloudPlatform/kubernetes.`,
The `BashCompletionFunction` option is really only valid/useful on the root command. Doing the above will cause `__kubectl_custom_func()` (`___custom_func()`) to be called when the built in processor was unable to find a solution. In the case of kubernetes a valid command might look something like `kubectl get pod [mypod]`. If you type `kubectl get pod [tab][tab]` the `__kubectl_customc_func()` will run because the cobra.Command only understood "kubectl" and "get." `__kubectl_custom_func()` will see that the cobra.Command is "kubectl_get" and will thus call another helper `__kubectl_get_resource()`. `__kubectl_get_resource` will look at the 'nouns' collected. In our example the only noun will be `pod`. So it will call `__kubectl_parse_get pod`. `__kubectl_parse_get` will actually call out to kubernetes and get any pods. It will then set `COMPREPLY` to valid pods!
-## Have the completions code complete your 'nouns'
-
-In the above example "pod" was assumed to already be typed. But if you want `kubectl get [tab][tab]` to show a list of valid "nouns" you have to set them. Simplified code from `kubectl get` looks like:
-
-```go
-validArgs []string = { "pod", "node", "service", "replicationcontroller" }
-
-cmd := &cobra.Command{
- Use: "get [(-o|--output=)json|yaml|template|...] (RESOURCE [NAME] | RESOURCE/NAME ...)",
- Short: "Display one or many resources",
- Long: get_long,
- Example: get_example,
- Run: func(cmd *cobra.Command, args []string) {
- err := RunGet(f, out, cmd, args)
- util.CheckErr(err)
- },
- ValidArgs: validArgs,
-}
-```
-
-Notice we put the "ValidArgs" on the "get" subcommand. Doing so will give results like
-
-```bash
-# kubectl get [tab][tab]
-node pod replicationcontroller service
-```
-
-## Plural form and shortcuts for nouns
-
-If your nouns have a number of aliases, you can define them alongside `ValidArgs` using `ArgAliases`:
-
-```go
-argAliases []string = { "pods", "nodes", "services", "svc", "replicationcontrollers", "rc" }
-
-cmd := &cobra.Command{
- ...
- ValidArgs: validArgs,
- ArgAliases: argAliases
-}
-```
-
-The aliases are not shown to the user on tab completion, but they are accepted as valid nouns by
-the completion algorithm if entered manually, e.g. in:
-
-```bash
-# kubectl get rc [tab][tab]
-backend frontend database
-```
-
-Note that without declaring `rc` as an alias, the completion algorithm would show the list of nouns
-in this example again instead of the replication controllers.
-
-## Mark flags as required
-
-Most of the time completions will only show subcommands. But if a flag is required to make a subcommand work, you probably want it to show up when the user types [tab][tab]. Marking a flag as 'Required' is incredibly easy.
-
-```go
-cmd.MarkFlagRequired("pod")
-cmd.MarkFlagRequired("container")
-```
-
-and you'll get something like
-
-```bash
-# kubectl exec [tab][tab][tab]
--c --container= -p --pod=
-```
-
-# Specify valid filename extensions for flags that take a filename
-
-In this example we use --filename= and expect to get a json or yaml file as the argument. To make this easier we annotate the --filename flag with valid filename extensions.
-
-```go
- annotations := []string{"json", "yaml", "yml"}
- annotation := make(map[string][]string)
- annotation[cobra.BashCompFilenameExt] = annotations
-
- flag := &pflag.Flag{
- Name: "filename",
- Shorthand: "f",
- Usage: usage,
- Value: value,
- DefValue: value.String(),
- Annotations: annotation,
- }
- cmd.Flags().AddFlag(flag)
-```
-
-Now when you run a command with this filename flag you'll get something like
-
-```bash
-# kubectl create -f
-test/ example/ rpmbuild/
-hello.yml test.json
-```
-
-So while there are many other files in the CWD it only shows me subdirs and those with valid extensions.
-
-# Specify custom flag completion
-
-Similar to the filename completion and filtering using cobra.BashCompFilenameExt, you can specify
-a custom flag completion function with cobra.BashCompCustom:

# Generating PowerShell Completions For Your Own cobra.Command
-Cobra can generate PowerShell completion scripts. Users need PowerShell version 5.0 or above, which comes with Windows 10 and can be downloaded separately for Windows 7 or 8.1. They can then write the completions to a file and source this file from their PowerShell profile, which is referenced by the `$Profile` environment variable. See `Get-Help about_Profiles` for more info about PowerShell profiles.
-
-# What's supported
-
-- Completion for subcommands using their `.Short` description
-- Completion for non-hidden flags using their `.Name` and `.Shorthand`
-
-# What's not yet supported
-
-- Command aliases
-- Required, filename or custom flags (they will work like normal flags)
-- Custom completion scripts
+Please refer to [Shell Completions](shell_completions.md#powershell-completions) for details.

+# Generating shell completions
+
+Cobra can generate shell completions for multiple shells.
+The currently supported shells are:
+- Bash
+- Zsh
+- fish
+- PowerShell
+
+Cobra will automatically provide your program with a fully functional `completion` command,
+similarly to how it provides the `help` command.
+
+## Creating your own completion command
+
+If you do not wish to use the default `completion` command, you can choose to
+provide your own, which will take precedence over the default one. (This also provides
+backwards-compatibility with programs that already have their own `completion` command.)
+
+If you are using the generator, you can create a completion command by running
+
+```bash
+cobra add completion
+```
+and then modifying the generated `cmd/completion.go` file to look something like this
+(writing the shell script to stdout allows the most flexible use):
+
+```go
+var completionCmd = &cobra.Command{
+ Use: "completion [bash|zsh|fish|powershell]",
+ Short: "Generate completion script",
+ Long: `To load completions:
+
+Bash:
+
+ $ source <(yourprogram completion bash)
+
+ # To load completions for each session, execute once:
+ # Linux:
+ $ yourprogram completion bash > /etc/bash_completion.d/yourprogram
+ # macOS:
+ $ yourprogram completion bash > /usr/local/etc/bash_completion.d/yourprogram
+
+Zsh:
+
+ # If shell completion is not already enabled in your environment,
+ # you will need to enable it. You can execute the following once:
+
+ $ echo "autoload -U compinit; compinit" >> ~/.zshrc
+
+ # To load completions for each session, execute once:
+ $ yourprogram completion zsh > "${fpath[1]}/_yourprogram"
+
+ # You will need to start a new shell for this setup to take effect.
+
+fish:
+
+ $ yourprogram completion fish | source
+
+ # To load completions for each session, execute once:
+ $ yourprogram completion fish > ~/.config/fish/completions/yourprogram.fish
+
+PowerShell:
+
+ PS> yourprogram completion powershell | Out-String | Invoke-Expression
+
+ # To load completions for every new session, run:
+ PS> yourprogram completion powershell > yourprogram.ps1
+ # and source this file from your PowerShell profile.
+`,
+ DisableFlagsInUseLine: true,
+ ValidArgs: []string{"bash", "zsh", "fish", "powershell"},
+ Args: cobra.ExactValidArgs(1),
+ Run: func(cmd *cobra.Command, args []string) {
+ switch args[0] {
+ case "bash":
+ cmd.Root().GenBashCompletion(os.Stdout)
+ case "zsh":
+ cmd.Root().GenZshCompletion(os.Stdout)
+ case "fish":
+ cmd.Root().GenFishCompletion(os.Stdout, true)
+ case "powershell":
+ cmd.Root().GenPowerShellCompletionWithDesc(os.Stdout)
+ }
+ },
+}
+```
+
+**Note:** The cobra generator may include messages printed to stdout, for example, if the config file is loaded; this will break the auto-completion script so must be removed.
+
+## Adapting the default completion command
+
+Cobra provides a few options for the default `completion` command. To configure such options you must set
+the `CompletionOptions` field on the *root* command.
+
+To tell Cobra *not* to provide the default `completion` command:
+```
+rootCmd.CompletionOptions.DisableDefaultCmd = true
+```
+
+To tell Cobra *not* to provide the user with the `--no-descriptions` flag to the completion sub-commands:
+```
+rootCmd.CompletionOptions.DisableNoDescFlag = true
+```
+
+To tell Cobra to completely disable descriptions for completions:
+```
+rootCmd.CompletionOptions.DisableDescriptions = true
+```
+
+# Customizing completions
+
+The generated completion scripts will automatically handle completing commands and flags. However, you can make your completions much more powerful by providing information to complete your program's nouns and flag values.
+
+## Completion of nouns
+
+### Static completion of nouns
+
+Cobra allows you to provide a pre-defined list of completion choices for your nouns using the `ValidArgs` field.
+For example, if you want `kubectl get [tab][tab]` to show a list of valid "nouns" you have to set them.
+Some simplified code from `kubectl get` looks like:
+
+```go
+validArgs []string = { "pod", "node", "service", "replicationcontroller" }
+
+cmd := &cobra.Command{
+ Use: "get [(-o|--output=)json|yaml|template|...] (RESOURCE [NAME] | RESOURCE/NAME ...)",
+ Short: "Display one or many resources",
+ Long: get_long,
+ Example: get_example,
+ Run: func(cmd *cobra.Command, args []string) {
+ cobra.CheckErr(RunGet(f, out, cmd, args))
+ },
+ ValidArgs: validArgs,
+}
+```
+
+Notice we put the `ValidArgs` field on the `get` sub-command. Doing so will give results like:
+
+```bash
+$ kubectl get [tab][tab]
+node pod replicationcontroller service
+```
+
+#### Aliases for nouns
+
+If your nouns have aliases, you can define them alongside `ValidArgs` using `ArgAliases`:
+
+```go
+argAliases []string = { "pods", "nodes", "services", "svc", "replicationcontrollers", "rc" }
+
+cmd := &cobra.Command{
+ ...
+ ValidArgs: validArgs,
+ ArgAliases: argAliases
+}
+```
+
+The aliases are not shown to the user on tab completion, but they are accepted as valid nouns by
+the completion algorithm if entered manually, e.g. in:
+
+```bash
+$ kubectl get rc [tab][tab]
+backend frontend database
+```
+
+Note that without declaring `rc` as an alias, the completion algorithm would not know to show the list of
+replication controllers following `rc`.
+
+### Dynamic completion of nouns
+
+In some cases it is not possible to provide a list of completions in advance. Instead, the list of completions must be determined at execution-time. In a similar fashion as for static completions, you can use the `ValidArgsFunction` field to provide a Go function that Cobra will execute when it needs the list of completion choices for the nouns of a command. Note that either `ValidArgs` or `ValidArgsFunction` can be used for a single cobra command, but not both.
+Simplified code from `helm status` looks like:
+
+```go
+cmd := &cobra.Command{
+ Use: "status RELEASE_NAME",
+ Short: "Display the status of the named release",
+ Long: status_long,
+ RunE: func(cmd *cobra.Command, args []string) {
+ RunGet(args[0])
+ },
+ ValidArgsFunction: func(cmd *cobra.Command, args []string, toComplete string) ([]string, cobra.ShellCompDirective) {
+ if len(args) != 0 {
+ return nil, cobra.ShellCompDirectiveNoFileComp
+ }
+ return getReleasesFromCluster(toComplete), cobra.ShellCompDirectiveNoFileComp
+ },
+}
+```
+Where `getReleasesFromCluster()` is a Go function that obtains the list of current Helm releases running on the Kubernetes cluster.
+Notice we put the `ValidArgsFunction` on the `status` sub-command. Let's assume the Helm releases on the cluster are: `harbor`, `notary`, `rook` and `thanos` then this dynamic completion will give results like:
+
+```bash
+$ helm status [tab][tab]
+harbor notary rook thanos
+```
+You may have noticed the use of `cobra.ShellCompDirective`. These directives are bit fields allowing to control some shell completion behaviors for your particular completion. You can combine them with the bit-or operator such as `cobra.ShellCompDirectiveNoSpace | cobra.ShellCompDirectiveNoFileComp`
+```go
+// Indicates that the shell will perform its default behavior after completions
+// have been provided (this implies none of the other directives).
+ShellCompDirectiveDefault
+
+// Indicates an error occurred and completions should be ignored.
+ShellCompDirectiveError
+
+// Indicates that the shell should not add a space after the completion,
+// even if there is a single completion provided.
+ShellCompDirectiveNoSpace
+
+// Indicates that the shell should not provide file completion even when
+// no completion is provided.
+ShellCompDirectiveNoFileComp
+
+// Indicates that the returned completions should be used as file extension filters.
+// For example, to complete only files of the form *.json or *.yaml:
+// return []string{"yaml", "json"}, ShellCompDirectiveFilterFileExt
+// For flags, using MarkFlagFilename() and MarkPersistentFlagFilename()
+// is a shortcut to using this directive explicitly.
+//
+ShellCompDirectiveFilterFileExt
+
+// Indicates that only directory names should be provided in file completion.
+// For example:
+// return nil, ShellCompDirectiveFilterDirs
+// For flags, using MarkFlagDirname() is a shortcut to using this directive explicitly.
+//
+// To request directory names within another directory, the returned completions
+// should specify a single directory name within which to search. For example,
+// to complete directories within "themes/":
+// return []string{"themes"}, ShellCompDirectiveFilterDirs
+//
+ShellCompDirectiveFilterDirs
+```
+
+***Note***: When using the `ValidArgsFunction`, Cobra will call your registered function after having parsed all flags and arguments provided in the command-line. You therefore don't need to do this parsing yourself. For example, when a user calls `helm status --namespace my-rook-ns [tab][tab]`, Cobra will call your registered `ValidArgsFunction` after having parsed the `--namespace` flag, as it would have done when calling the `RunE` function.
+
+#### Debugging
+
+Cobra achieves dynamic completion through the use of a hidden command called by the completion script. To debug your Go completion code, you can call this hidden command directly:
+```bash
+$ helm __complete status har
+harbor
+:4
+Completion ended with directive: ShellCompDirectiveNoFileComp # This is on stderr
+```
+***Important:*** If the noun to complete is empty (when the user has not yet typed any letters of that noun), you must pass an empty parameter to the `__complete` command:
+```bash
+$ helm __complete status ""
+harbor
+notary
+rook
+thanos
+:4
+Completion ended with directive: ShellCompDirectiveNoFileComp # This is on stderr
+```
+Calling the `__complete` command directly allows you to run the Go debugger to troubleshoot your code. You can also add printouts to your code; Cobra provides the following functions to use for printouts in Go completion code:
+```go
+// Prints to the completion script debug file (if BASH_COMP_DEBUG_FILE
+// is set to a file path) and optionally prints to stderr.
+cobra.CompDebug(msg string, printToStdErr bool) {
+cobra.CompDebugln(msg string, printToStdErr bool)
+
+// Prints to the completion script debug file (if BASH_COMP_DEBUG_FILE
+// is set to a file path) and to stderr.
+cobra.CompError(msg string)
+cobra.CompErrorln(msg string)
+```
+***Important:*** You should **not** leave traces that print directly to stdout in your completion code as they will be interpreted as completion choices by the completion script. Instead, use the cobra-provided debugging traces functions mentioned above.
+
+## Completions for flags
+
+### Mark flags as required
+
+Most of the time completions will only show sub-commands. But if a flag is required to make a sub-command work, you probably want it to show up when the user types [tab][tab]. You can mark a flag as 'Required' like so:
+
+```go
+cmd.MarkFlagRequired("pod")
+cmd.MarkFlagRequired("container")
+```
+
+and you'll get something like
+
+```bash
+$ kubectl exec [tab][tab]
+-c --container= -p --pod=
+```
+
+### Specify dynamic flag completion
+
+As for nouns, Cobra provides a way of defining dynamic completion of flags. To provide a Go function that Cobra will execute when it needs the list of completion choices for a flag, you must register the function using the `command.RegisterFlagCompletionFunc()` function.
+
+```go
+flagName := "output"
+cmd.RegisterFlagCompletionFunc(flagName, func(cmd *cobra.Command, args []string, toComplete string) ([]string, cobra.ShellCompDirective) {
+ return []string{"json", "table", "yaml"}, cobra.ShellCompDirectiveDefault
+})
+```
+Notice that calling `RegisterFlagCompletionFunc()` is done through the `command` with which the flag is associated. In our example this dynamic completion will give results like so:
+
+```bash
+$ helm status --output [tab][tab]
+json table yaml
+```
+
+#### Debugging
+
+You can also easily debug your Go completion code for flags:
+```bash
+$ helm __complete status --output ""
+json
+table
+yaml
+:4
+Completion ended with directive: ShellCompDirectiveNoFileComp # This is on stderr
+```
+***Important:*** You should **not** leave traces that print to stdout in your completion code as they will be interpreted as completion choices by the completion script. Instead, use the cobra-provided debugging traces functions mentioned further above.
+
+### Specify valid filename extensions for flags that take a filename
+
+To limit completions of flag values to file names with certain extensions you can either use the different `MarkFlagFilename()` functions or a combination of `RegisterFlagCompletionFunc()` and `ShellCompDirectiveFilterFileExt`, like so:
+```go
+flagName := "output"
+cmd.MarkFlagFilename(flagName, "yaml", "json")
+```
+or
+```go
+flagName := "output"
+cmd.RegisterFlagCompletionFunc(flagName, func(cmd *cobra.Command, args []string, toComplete string) ([]string, cobra.ShellCompDirective) {
+ return []string{"yaml", "json"}, ShellCompDirectiveFilterFileExt})
+```
+
+### Limit flag completions to directory names
+
+To limit completions of flag values to directory names you can either use the `MarkFlagDirname()` functions or a combination of `RegisterFlagCompletionFunc()` and `ShellCompDirectiveFilterDirs`, like so:
+```go
+flagName := "output"
+cmd.MarkFlagDirname(flagName)
+```
+or
+```go
+flagName := "output"
+cmd.RegisterFlagCompletionFunc(flagName, func(cmd *cobra.Command, args []string, toComplete string) ([]string, cobra.ShellCompDirective) {
+ return nil, cobra.ShellCompDirectiveFilterDirs
+})
+```
+To limit completions of flag values to directory names *within another directory* you can use a combination of `RegisterFlagCompletionFunc()` and `ShellCompDirectiveFilterDirs` like so:
+```go
+flagName := "output"
+cmd.RegisterFlagCompletionFunc(flagName, func(cmd *cobra.Command, args []string, toComplete string) ([]string, cobra.ShellCompDirective) {
+ return []string{"themes"}, cobra.ShellCompDirectiveFilterDirs
+})
+```
+### Descriptions for completions
+
+Cobra provides support for completion descriptions. Such descriptions are supported for each shell
+(however, for bash, it is only available in the [completion V2 version](#bash-completion-v2)).
+For commands and flags, Cobra will provide the descriptions automatically, based on usage information.
+For example, using zsh:
+```
+$ helm s[tab]
+search -- search for a keyword in charts
+show -- show information of a chart
+status -- displays the status of the named release
+```
+while using fish:
+```
+$ helm s[tab]
+search (search for a keyword in charts) show (show information of a chart) status (displays the status of the named release)
+```
+
+Cobra allows you to add descriptions to your own completions. Simply add the description text after each completion, following a `\t` separator. This technique applies to completions returned by `ValidArgs`, `ValidArgsFunction` and `RegisterFlagCompletionFunc()`. For example:
+```go
+ValidArgsFunction: func(cmd *cobra.Command, args []string, toComplete string) ([]string, cobra.ShellCompDirective) {
+ return []string{"harbor\tAn image registry", "thanos\tLong-term metrics"}, cobra.ShellCompDirectiveNoFileComp
+}}
+```
+or
+```go
+ValidArgs: []string{"bash\tCompletions for bash", "zsh\tCompletions for zsh"}
+```
+## Bash completions
+
+### Dependencies
+
+The bash completion script generated by Cobra requires the `bash_completion` package. You should update the help text of your completion command to show how to install the `bash_completion` package ([Kubectl docs](https://kubernetes.io/docs/tasks/tools/install-kubectl/#enabling-shell-autocompletion))
+
+### Aliases
+
+You can also configure `bash` aliases for your program and they will also support completions.
+
+```bash
+alias aliasname=origcommand
+complete -o default -F __start_origcommand aliasname
+
+# and now when you run `aliasname` completion will make
+# suggestions as it did for `origcommand`.
+
+$ aliasname
+completion firstcommand secondcommand
+```
+### Bash legacy dynamic completions
+
+For backward compatibility, Cobra still supports its bash legacy dynamic completion solution.
+Please refer to [Bash Completions](bash_completions.md) for details.
+
+### Bash completion V2
+
+Cobra provides two versions for bash completion. The original bash completion (which started it all!) can be used by calling
+`GenBashCompletion()` or `GenBashCompletionFile()`.
+
+A new V2 bash completion version is also available. This version can be used by calling `GenBashCompletionV2()` or
+`GenBashCompletionFileV2()`. The V2 version does **not** support the legacy dynamic completion
+(see [Bash Completions](bash_completions.md)) but instead works only with the Go dynamic completion
+solution described in this document.
+Unless your program already uses the legacy dynamic completion solution, it is recommended that you use the bash
+completion V2 solution which provides the following extra features:
+- Supports completion descriptions (like the other shells)
+- Small completion script of less than 300 lines (v1 generates scripts of thousands of lines; `kubectl` for example has a bash v1 completion script of over 13K lines)
+- Streamlined user experience thanks to a completion behavior aligned with the other shells
+
+`Bash` completion V2 supports descriptions for completions. When calling `GenBashCompletionV2()` or `GenBashCompletionFileV2()`
+you must provide these functions with a parameter indicating if the completions should be annotated with a description; Cobra
+will provide the description automatically based on usage information. You can choose to make this option configurable by
+your users.
+
+```
+# With descriptions
+$ helm s[tab][tab]
+search (search for a keyword in charts) status (display the status of the named release)
+show (show information of a chart)
+
+# Without descriptions
+$ helm s[tab][tab]
+search show status
+```
+**Note**: Cobra's default `completion` command uses bash completion V2. If for some reason you need to use bash completion V1, you will need to implement your own `completion` command.
+## Zsh completions
+
+Cobra supports native zsh completion generated from the root `cobra.Command`.
+The generated completion script should be put somewhere in your `$fpath` and be named
+`_`. You will need to start a new shell for the completions to become available.
+
+Zsh supports descriptions for completions. Cobra will provide the description automatically,
+based on usage information. Cobra provides a way to completely disable such descriptions by
+using `GenZshCompletionNoDesc()` or `GenZshCompletionFileNoDesc()`. You can choose to make
+this a configurable option to your users.
+```
+# With descriptions
+$ helm s[tab]
+search -- search for a keyword in charts
+show -- show information of a chart
+status -- displays the status of the named release
+
+# Without descriptions
+$ helm s[tab]
+search show status
+```
+*Note*: Because of backward-compatibility requirements, we were forced to have a different API to disable completion descriptions between `zsh` and `fish`.
+
+### Limitations
+
+* Custom completions implemented in Bash scripting (legacy) are not supported and will be ignored for `zsh` (including the use of the `BashCompCustom` flag annotation).
+ * You should instead use `ValidArgsFunction` and `RegisterFlagCompletionFunc()` which are portable to the different shells (`bash`, `zsh`, `fish`, `powershell`).
+* The function `MarkFlagCustom()` is not supported and will be ignored for `zsh`.
+ * You should instead use `RegisterFlagCompletionFunc()`.
+
+### Zsh completions standardization
+
+Cobra 1.1 standardized its zsh completion support to align it with its other shell completions. Although the API was kept backward-compatible, some small changes in behavior were introduced.
+Please refer to [Zsh Completions](zsh_completions.md) for details.
+
+## fish completions
+
+Cobra supports native fish completions generated from the root `cobra.Command`. You can use the `command.GenFishCompletion()` or `command.GenFishCompletionFile()` functions. You must provide these functions with a parameter indicating if the completions should be annotated with a description; Cobra will provide the description automatically based on usage information. You can choose to make this option configurable by your users.
+```
+# With descriptions
+$ helm s[tab]
+search (search for a keyword in charts) show (show information of a chart) status (displays the status of the named release)
+
+# Without descriptions
+$ helm s[tab]
+search show status
+```
+*Note*: Because of backward-compatibility requirements, we were forced to have a different API to disable completion descriptions between `zsh` and `fish`.
+
+### Limitations
+
+* Custom completions implemented in bash scripting (legacy) are not supported and will be ignored for `fish` (including the use of the `BashCompCustom` flag annotation).
+ * You should instead use `ValidArgsFunction` and `RegisterFlagCompletionFunc()` which are portable to the different shells (`bash`, `zsh`, `fish`, `powershell`).
+* The function `MarkFlagCustom()` is not supported and will be ignored for `fish`.
+ * You should instead use `RegisterFlagCompletionFunc()`.
+* The following flag completion annotations are not supported and will be ignored for `fish`:
+ * `BashCompFilenameExt` (filtering by file extension)
+ * `BashCompSubdirsInDir` (filtering by directory)
+* The functions corresponding to the above annotations are consequently not supported and will be ignored for `fish`:
+ * `MarkFlagFilename()` and `MarkPersistentFlagFilename()` (filtering by file extension)
+ * `MarkFlagDirname()` and `MarkPersistentFlagDirname()` (filtering by directory)
+* Similarly, the following completion directives are not supported and will be ignored for `fish`:
+ * `ShellCompDirectiveFilterFileExt` (filtering by file extension)
+ * `ShellCompDirectiveFilterDirs` (filtering by directory)
+
+## PowerShell completions
+
+Cobra supports native PowerShell completions generated from the root `cobra.Command`. You can use the `command.GenPowerShellCompletion()` or `command.GenPowerShellCompletionFile()` functions. To include descriptions use `command.GenPowerShellCompletionWithDesc()` and `command.GenPowerShellCompletionFileWithDesc()`. Cobra will provide the description automatically based on usage information. You can choose to make this option configurable by your users.
+
+The script is designed to support all three PowerShell completion modes:
+
+* TabCompleteNext (default windows style - on each key press the next option is displayed)
+* Complete (works like bash)
+* MenuComplete (works like zsh)
+
+You set the mode with `Set-PSReadLineKeyHandler -Key Tab -Function `. Descriptions are only displayed when using the `Complete` or `MenuComplete` mode.
+
+Users need PowerShell version 5.0 or above, which comes with Windows 10 and can be downloaded separately for Windows 7 or 8.1. They can then write the completions to a file and source this file from their PowerShell profile, which is referenced by the `$Profile` environment variable. See `Get-Help about_Profiles` for more info about PowerShell profiles.
+
+```
+# With descriptions and Mode 'Complete'
+$ helm s[tab]
+search (search for a keyword in charts) show (show information of a chart) status (displays the status of the named release)
+
+# With descriptions and Mode 'MenuComplete' The description of the current selected value will be displayed below the suggestions.
+$ helm s[tab]
+search show status
+
+search for a keyword in charts
+
+# Without descriptions
+$ helm s[tab]
+search show status
+```
+
+### Limitations
+
+* Custom completions implemented in bash scripting (legacy) are not supported and will be ignored for `powershell` (including the use of the `BashCompCustom` flag annotation).
+ * You should instead use `ValidArgsFunction` and `RegisterFlagCompletionFunc()` which are portable to the different shells (`bash`, `zsh`, `fish`, `powershell`).
+* The function `MarkFlagCustom()` is not supported and will be ignored for `powershell`.
+ * You should instead use `RegisterFlagCompletionFunc()`.
+* The following flag completion annotations are not supported and will be ignored for `powershell`:
+ * `BashCompFilenameExt` (filtering by file extension)
+ * `BashCompSubdirsInDir` (filtering by directory)
+* The functions corresponding to the above annotations are consequently not supported and will be ignored for `powershell`:
+ * `MarkFlagFilename()` and `MarkPersistentFlagFilename()` (filtering by file extension)
+ * `MarkFlagDirname()` and `MarkPersistentFlagDirname()` (filtering by directory)
+* Similarly, the following completion directives are not supported and will be ignored for `powershell`:
+ * `ShellCompDirectiveFilterFileExt` (filtering by file extension)
+ * `ShellCompDirectiveFilterDirs` (filtering by directory)

+# User Guide
+
+While you are welcome to provide your own organization, typically a Cobra-based
+application will follow the following organizational structure:
+
+```
+ ▾ appName/
+ ▾ cmd/
+ add.go
+ your.go
+ commands.go
+ here.go
+ main.go
+```
+
+In a Cobra app, typically the main.go file is very bare. It serves one purpose: initializing Cobra.
+
+```go
+package main
+
+import (
+ "{pathToYourApp}/cmd"
+)
+
+func main() {
+ cmd.Execute()
+}
+```
+
+## Using the Cobra Generator
+
+Cobra provides its own program that will create your application and add any
+commands you want. It's the easiest way to incorporate Cobra into your application.
+
+[Here](https://github.com/spf13/cobra/blob/master/cobra/README.md) you can find more information about it.
+
+## Using the Cobra Library
+
+To manually implement Cobra you need to create a bare main.go file and a rootCmd file.
+You will optionally provide additional commands as you see fit.
+
+### Create rootCmd
+
+Cobra doesn't require any special constructors. Simply create your commands.
+
+Ideally you place this in app/cmd/root.go:
+
+```go
+var rootCmd = &cobra.Command{
+ Use: "hugo",
+ Short: "Hugo is a very fast static site generator",
+ Long: `A Fast and Flexible Static Site Generator built with
+ love by spf13 and friends in Go.
+ Complete documentation is available at http://hugo.spf13.com`,
+ Run: func(cmd *cobra.Command, args []string) {
+ // Do Stuff Here
+ },
+}
+
+func Execute() {
+ if err := rootCmd.Execute(); err != nil {
+ fmt.Fprintln(os.Stderr, err)
+ os.Exit(1)
+ }
+}
+```
+
+You will additionally define flags and handle configuration in your init() function.
+
+For example cmd/root.go:
+
+```go
+package cmd
+
+import (
+ "fmt"
+ "os"
+
+ "github.com/spf13/cobra"
+ "github.com/spf13/viper"
+)
+
+var (
+ // Used for flags.
+ cfgFile string
+ userLicense string
+
+ rootCmd = &cobra.Command{
+ Use: "cobra",
+ Short: "A generator for Cobra based Applications",
+ Long: `Cobra is a CLI library for Go that empowers applications.
+This application is a tool to generate the needed files
+to quickly create a Cobra application.`,
+ }
+)
+
+// Execute executes the root command.
+func Execute() error {
+ return rootCmd.Execute()
+}
+
+func init() {
+ cobra.OnInitialize(initConfig)
+
+ rootCmd.PersistentFlags().StringVar(&cfgFile, "config", "", "config file (default is $HOME/.cobra.yaml)")
+ rootCmd.PersistentFlags().StringP("author", "a", "YOUR NAME", "author name for copyright attribution")
+ rootCmd.PersistentFlags().StringVarP(&userLicense, "license", "l", "", "name of license for the project")
+ rootCmd.PersistentFlags().Bool("viper", true, "use Viper for configuration")
+ viper.BindPFlag("author", rootCmd.PersistentFlags().Lookup("author"))
+ viper.BindPFlag("useViper", rootCmd.PersistentFlags().Lookup("viper"))
+ viper.SetDefault("author", "NAME HERE ")
+ viper.SetDefault("license", "apache")
+
+ rootCmd.AddCommand(addCmd)
+ rootCmd.AddCommand(initCmd)
+}
+
+func initConfig() {
+ if cfgFile != "" {
+ // Use config file from the flag.
+ viper.SetConfigFile(cfgFile)
+ } else {
+ // Find home directory.
+ home, err := os.UserHomeDir()
+ cobra.CheckErr(err)
+
+ // Search config in home directory with name ".cobra" (without extension).
+ viper.AddConfigPath(home)
+ viper.SetConfigType("yaml")
+ viper.SetConfigName(".cobra")
+ }
+
+ viper.AutomaticEnv()
+
+ if err := viper.ReadInConfig(); err == nil {
+ fmt.Println("Using config file:", viper.ConfigFileUsed())
+ }
+}
+```
+
+### Create your main.go
+
+With the root command you need to have your main function execute it.
+Execute should be run on the root for clarity, though it can be called on any command.
+
+In a Cobra app, typically the main.go file is very bare. It serves one purpose: to initialize Cobra.
+
+```go
+package main
+
+import (
+ "{pathToYourApp}/cmd"
+)
+
+func main() {
+ cmd.Execute()
+}
+```
+
+### Create additional commands
+
+Additional commands can be defined and typically are each given their own file
+inside of the cmd/ directory.
+
+If you wanted to create a version command you would create cmd/version.go and
+populate it with the following:
+
+```go
+package cmd
+
+import (
+ "fmt"
+
+ "github.com/spf13/cobra"
+)
+
+func init() {
+ rootCmd.AddCommand(versionCmd)
+}
+
+var versionCmd = &cobra.Command{
+ Use: "version",
+ Short: "Print the version number of Hugo",
+ Long: `All software has versions. This is Hugo's`,
+ Run: func(cmd *cobra.Command, args []string) {
+ fmt.Println("Hugo Static Site Generator v0.9 -- HEAD")
+ },
+}
+```
+
+### Returning and handling errors
+
+If you wish to return an error to the caller of a command, `RunE` can be used.
+
+```go
+package cmd
+
+import (
+ "fmt"
+
+ "github.com/spf13/cobra"
+)
+
+func init() {
+ rootCmd.AddCommand(tryCmd)
+}
+
+var tryCmd = &cobra.Command{
+ Use: "try",
+ Short: "Try and possibly fail at something",
+ RunE: func(cmd *cobra.Command, args []string) error {
+ if err := someFunc(); err != nil {
+ return err
+ }
+ return nil
+ },
+}
+```
+
+The error can then be caught at the execute function call.
+
+## Working with Flags
+
+Flags provide modifiers to control how the action command operates.
+
+### Assign flags to a command
+
+Since the flags are defined and used in different locations, we need to
+define a variable outside with the correct scope to assign the flag to
+work with.
+
+```go
+var Verbose bool
+var Source string
+```
+
+There are two different approaches to assign a flag.
+
+### Persistent Flags
+
+A flag can be 'persistent', meaning that this flag will be available to the
+command it's assigned to as well as every command under that command. For
+global flags, assign a flag as a persistent flag on the root.
+
+```go
+rootCmd.PersistentFlags().BoolVarP(&Verbose, "verbose", "v", false, "verbose output")
+```
+
+### Local Flags
+
+A flag can also be assigned locally, which will only apply to that specific command.
+
+```go
+localCmd.Flags().StringVarP(&Source, "source", "s", "", "Source directory to read from")
+```
+
+### Local Flag on Parent Commands
+
+By default, Cobra only parses local flags on the target command, and any local flags on
+parent commands are ignored. By enabling `Command.TraverseChildren`, Cobra will
+parse local flags on each command before executing the target command.
+
+```go
+command := cobra.Command{
+ Use: "print [OPTIONS] [COMMANDS]",
+ TraverseChildren: true,
+}
+```
+
+### Bind Flags with Config
+
+You can also bind your flags with [viper](https://github.com/spf13/viper):
+```go
+var author string
+
+func init() {
+ rootCmd.PersistentFlags().StringVar(&author, "author", "YOUR NAME", "Author name for copyright attribution")
+ viper.BindPFlag("author", rootCmd.PersistentFlags().Lookup("author"))
+}
+```
+
+In this example, the persistent flag `author` is bound with `viper`.
+**Note**: the variable `author` will not be set to the value from config,
+when the `--author` flag is not provided by user.
+
+More in [viper documentation](https://github.com/spf13/viper#working-with-flags).
+
+### Required flags
+
+Flags are optional by default. If instead you wish your command to report an error
+when a flag has not been set, mark it as required:
+```go
+rootCmd.Flags().StringVarP(&Region, "region", "r", "", "AWS region (required)")
+rootCmd.MarkFlagRequired("region")
+```
+
+Or, for persistent flags:
+```go
+rootCmd.PersistentFlags().StringVarP(&Region, "region", "r", "", "AWS region (required)")
+rootCmd.MarkPersistentFlagRequired("region")
+```
+
+## Positional and Custom Arguments
+
+Validation of positional arguments can be specified using the `Args` field
+of `Command`.
+
+The following validators are built in:
+
+- `NoArgs` - the command will report an error if there are any positional args.
+- `ArbitraryArgs` - the command will accept any args.
+- `OnlyValidArgs` - the command will report an error if there are any positional args that are not in the `ValidArgs` field of `Command`.
+- `MinimumNArgs(int)` - the command will report an error if there are not at least N positional args.
+- `MaximumNArgs(int)` - the command will report an error if there are more than N positional args.
+- `ExactArgs(int)` - the command will report an error if there are not exactly N positional args.
+- `ExactValidArgs(int)` - the command will report an error if there are not exactly N positional args OR if there are any positional args that are not in the `ValidArgs` field of `Command`
+- `RangeArgs(min, max)` - the command will report an error if the number of args is not between the minimum and maximum number of expected args.
+
+An example of setting the custom validator:
+
+```go
+var cmd = &cobra.Command{
+ Short: "hello",
+ Args: func(cmd *cobra.Command, args []string) error {
+ if len(args) < 1 {
+ return errors.New("requires a color argument")
+ }
+ if myapp.IsValidColor(args[0]) {
+ return nil
+ }
+ return fmt.Errorf("invalid color specified: %s", args[0])
+ },
+ Run: func(cmd *cobra.Command, args []string) {
+ fmt.Println("Hello, World!")
+ },
+}
+```
+
+## Example
+
+In the example below, we have defined three commands. Two are at the top level
+and one (cmdTimes) is a child of one of the top commands. In this case the root
+is not executable, meaning that a subcommand is required. This is accomplished
+by not providing a 'Run' for the 'rootCmd'.
+
+We have only defined one flag for a single command.
+
+More documentation about flags is available at https://github.com/spf13/pflag
+
+```go
+package main
+
+import (
+ "fmt"
+ "strings"
+
+ "github.com/spf13/cobra"
+)
+
+func main() {
+ var echoTimes int
+
+ var cmdPrint = &cobra.Command{
+ Use: "print [string to print]",
+ Short: "Print anything to the screen",
+ Long: `print is for printing anything back to the screen.
+For many years people have printed back to the screen.`,
+ Args: cobra.MinimumNArgs(1),
+ Run: func(cmd *cobra.Command, args []string) {
+ fmt.Println("Print: " + strings.Join(args, " "))
+ },
+ }
+
+ var cmdEcho = &cobra.Command{
+ Use: "echo [string to echo]",
+ Short: "Echo anything to the screen",
+ Long: `echo is for echoing anything back.
+Echo works a lot like print, except it has a child command.`,
+ Args: cobra.MinimumNArgs(1),
+ Run: func(cmd *cobra.Command, args []string) {
+ fmt.Println("Echo: " + strings.Join(args, " "))
+ },
+ }
+
+ var cmdTimes = &cobra.Command{
+ Use: "times [string to echo]",
+ Short: "Echo anything to the screen more times",
+ Long: `echo things multiple times back to the user by providing
+a count and a string.`,
+ Args: cobra.MinimumNArgs(1),
+ Run: func(cmd *cobra.Command, args []string) {
+ for i := 0; i < echoTimes; i++ {
+ fmt.Println("Echo: " + strings.Join(args, " "))
+ }
+ },
+ }
+
+ cmdTimes.Flags().IntVarP(&echoTimes, "times", "t", 1, "times to echo the input")
+
+ var rootCmd = &cobra.Command{Use: "app"}
+ rootCmd.AddCommand(cmdPrint, cmdEcho)
+ cmdEcho.AddCommand(cmdTimes)
+ rootCmd.Execute()
+}
+```
+

+
+## Help Command
+
+Cobra automatically adds a help command to your application when you have subcommands.
+This will be called when a user runs 'app help'. Additionally, help will also
+support all other commands as input. Say, for instance, you have a command called
+'create' without any additional configuration; Cobra will work when 'app help
+create' is called. Every command will automatically have the '--help' flag added.
+
+### Example
+
+The following output is automatically generated by Cobra. Nothing beyond the
+command and flag definitions are needed.
+
+ $ cobra help
+
+ Cobra is a CLI library for Go that empowers applications.
+ This application is a tool to generate the needed files
+ to quickly create a Cobra application.
+
+ Usage:
+ cobra [command]
+
+ Available Commands:
+ add Add a command to a Cobra Application
+ help Help about any command
+ init Initialize a Cobra Application
+
+ Flags:
+ -a, --author string author name for copyright attribution (default "YOUR NAME")
+ --config string config file (default is $HOME/.cobra.yaml)
+ -h, --help help for cobra
+ -l, --license string name of license for the project
+ --viper use Viper for configuration (default true)
+
+ Use "cobra [command] --help" for more information about a command.
+
+
+Help is just a command like any other. There is no special logic or behavior
+around it. In fact, you can provide your own if you want.
+
+### Defining your own help
+
+You can provide your own Help command or your own template for the default command to use
+with following functions:
+
+```go
+cmd.SetHelpCommand(cmd *Command)
+cmd.SetHelpFunc(f func(*Command, []string))
+cmd.SetHelpTemplate(s string)
+```
+
+The latter two will also apply to any children commands.
+
+## Usage Message
+
+When the user provides an invalid flag or invalid command, Cobra responds by
+showing the user the 'usage'.
+
+### Example
+You may recognize this from the help above. That's because the default help
+embeds the usage as part of its output.
+
+ $ cobra --invalid
+ Error: unknown flag: --invalid
+ Usage:
+ cobra [command]
+
+ Available Commands:
+ add Add a command to a Cobra Application
+ help Help about any command
+ init Initialize a Cobra Application
+
+ Flags:
+ -a, --author string author name for copyright attribution (default "YOUR NAME")
+ --config string config file (default is $HOME/.cobra.yaml)
+ -h, --help help for cobra
+ -l, --license string name of license for the project
+ --viper use Viper for configuration (default true)
+
+ Use "cobra [command] --help" for more information about a command.
+
+### Defining your own usage
+You can provide your own usage function or template for Cobra to use.
+Like help, the function and template are overridable through public methods:
+
+```go
+cmd.SetUsageFunc(f func(*Command) error)
+cmd.SetUsageTemplate(s string)
+```
+
+## Version Flag
+
+Cobra adds a top-level '--version' flag if the Version field is set on the root command.
+Running an application with the '--version' flag will print the version to stdout using
+the version template. The template can be customized using the
+`cmd.SetVersionTemplate(s string)` function.
+
+## PreRun and PostRun Hooks
+
+It is possible to run functions before or after the main `Run` function of your command. The `PersistentPreRun` and `PreRun` functions will be executed before `Run`. `PersistentPostRun` and `PostRun` will be executed after `Run`. The `Persistent*Run` functions will be inherited by children if they do not declare their own. These functions are run in the following order:
+
+- `PersistentPreRun`
+- `PreRun`
+- `Run`
+- `PostRun`
+- `PersistentPostRun`
+
+An example of two commands which use all of these features is below. When the subcommand is executed, it will run the root command's `PersistentPreRun` but not the root command's `PersistentPostRun`:
+
+```go
+package main
+
+import (
+ "fmt"
+
+ "github.com/spf13/cobra"
+)
+
+func main() {
+
+ var rootCmd = &cobra.Command{
+ Use: "root [sub]",
+ Short: "My root command",
+ PersistentPreRun: func(cmd *cobra.Command, args []string) {
+ fmt.Printf("Inside rootCmd PersistentPreRun with args: %v\n", args)
+ },
+ PreRun: func(cmd *cobra.Command, args []string) {
+ fmt.Printf("Inside rootCmd PreRun with args: %v\n", args)
+ },
+ Run: func(cmd *cobra.Command, args []string) {
+ fmt.Printf("Inside rootCmd Run with args: %v\n", args)
+ },
+ PostRun: func(cmd *cobra.Command, args []string) {
+ fmt.Printf("Inside rootCmd PostRun with args: %v\n", args)
+ },
+ PersistentPostRun: func(cmd *cobra.Command, args []string) {
+ fmt.Printf("Inside rootCmd PersistentPostRun with args: %v\n", args)
+ },
+ }
+
+ var subCmd = &cobra.Command{
+ Use: "sub [no options!]",
+ Short: "My subcommand",
+ PreRun: func(cmd *cobra.Command, args []string) {
+ fmt.Printf("Inside subCmd PreRun with args: %v\n", args)
+ },
+ Run: func(cmd *cobra.Command, args []string) {
+ fmt.Printf("Inside subCmd Run with args: %v\n", args)
+ },
+ PostRun: func(cmd *cobra.Command, args []string) {
+ fmt.Printf("Inside subCmd PostRun with args: %v\n", args)
+ },
+ PersistentPostRun: func(cmd *cobra.Command, args []string) {
+ fmt.Printf("Inside subCmd PersistentPostRun with args: %v\n", args)
+ },
+ }
+
+ rootCmd.AddCommand(subCmd)
+
+ rootCmd.SetArgs([]string{""})
+ rootCmd.Execute()
+ fmt.Println()
+ rootCmd.SetArgs([]string{"sub", "arg1", "arg2"})
+ rootCmd.Execute()
+}
+```
+
+Output:
+```
+Inside rootCmd PersistentPreRun with args: []
+Inside rootCmd PreRun with args: []
+Inside rootCmd Run with args: []
+Inside rootCmd PostRun with args: []
+Inside rootCmd PersistentPostRun with args: []
+
+Inside rootCmd PersistentPreRun with args: [arg1 arg2]
+Inside subCmd PreRun with args: [arg1 arg2]
+Inside subCmd Run with args: [arg1 arg2]
+Inside subCmd PostRun with args: [arg1 arg2]
+Inside subCmd PersistentPostRun with args: [arg1 arg2]
+```
+
+## Suggestions when "unknown command" happens
+
+Cobra will print automatic suggestions when "unknown command" errors happen. This allows Cobra to behave similarly to the `git` command when a typo happens. For example:
+
+```
+$ hugo srever
+Error: unknown command "srever" for "hugo"
+
+Did you mean this?
+ server
+
+Run 'hugo --help' for usage.
+```
+
+Suggestions are automatic based on every subcommand registered and use an implementation of [Levenshtein distance](http://en.wikipedia.org/wiki/Levenshtein_distance). Every registered command that matches a minimum distance of 2 (ignoring case) will be displayed as a suggestion.
+
+If you need to disable suggestions or tweak the string distance in your command, use:
+
+```go
+command.DisableSuggestions = true
+```
+
+or
+
+```go
+command.SuggestionsMinimumDistance = 1
+```
+
+You can also explicitly set names for which a given command will be suggested using the `SuggestFor` attribute. This allows suggestions for strings that are not close in terms of string distance, but makes sense in your set of commands and for some which you don't want aliases. Example:
+
+```
+$ kubectl remove
+Error: unknown command "remove" for "kubectl"
+
+Did you mean this?
+ delete
+
+Run 'kubectl help' for usage.
+```
+
+## Generating documentation for your command
+
+Cobra can generate documentation based on subcommands, flags, etc. Read more about it in the [docs generation documentation](doc/README.md).
+
+## Generating shell completions
+
+Cobra can generate a shell-completion file for the following shells: bash, zsh, fish, PowerShell. If you add more information to your commands, these completions can be amazingly powerful and flexible. Read more about it in [Shell Completions](shell_completions.md).

-## Generating Zsh Completion for your cobra.Command
-
-Cobra supports native Zsh completion generated from the root `cobra.Command`.
-The generated completion script should be put somewhere in your `$fpath` named
-`_`.
-
-### What's Supported
-
-* Completion for all non-hidden subcommands using their `.Short` description.
-* Completion for all non-hidden flags using the following rules:
- * Filename completion works by marking the flag with `cmd.MarkFlagFilename...`
- family of commands.
- * The requirement for argument to the flag is decided by the `.NoOptDefVal`
- flag value - if it's empty then completion will expect an argument.
- * Flags of one of the various `*Array` and `*Slice` types supports multiple
- specifications (with or without argument depending on the specific type).
-* Completion of positional arguments using the following rules:
- * Argument position for all options below starts at `1`. If argument position
- `0` is requested it will raise an error.
- * Use `command.MarkZshCompPositionalArgumentFile` to complete filenames. Glob
- patterns (e.g. `"*.log"`) are optional - if not specified it will offer to
- complete all file types.
- * Use `command.MarkZshCompPositionalArgumentWords` to offer specific words for
- completion. At least one word is required.
- * It's possible to specify completion for some arguments and leave some
- unspecified (e.g. offer words for second argument but nothing for first
- argument). This will cause no completion for first argument but words
- completion for second argument.
- * If no argument completion was specified for 1st argument (but optionally was
- specified for 2nd) and the command has `ValidArgs` it will be used as
- completion options for 1st argument.
- * Argument completions only offered for commands with no subcommands.
-
-### What's not yet Supported
-
-* Custom completion scripts are not supported yet (We should probably create zsh
- specific one, doesn't make sense to re-use the bash one as the functions will
- be different).
-* Whatever other feature you're looking for and doesn't exist :)
+## Generating Zsh Completion For Your cobra.Command
+
+Please refer to [Shell Completions](shell_completions.md) for details.
+
+## Zsh completions standardization
+
+Cobra 1.1 standardized its zsh completion support to align it with its other shell completions. Although the API was kept backwards-compatible, some small changes in behavior were introduced.
+
+### Deprecation summary
+
+See further below for more details on these deprecations.
+
+* `cmd.MarkZshCompPositionalArgumentFile(pos, []string{})` is no longer needed. It is therefore **deprecated** and silently ignored.
+* `cmd.MarkZshCompPositionalArgumentFile(pos, glob[])` is **deprecated** and silently ignored.
+ * Instead use `ValidArgsFunction` with `ShellCompDirectiveFilterFileExt`.
+* `cmd.MarkZshCompPositionalArgumentWords()` is **deprecated** and silently ignored.
+ * Instead use `ValidArgsFunction`.
+
+### Behavioral changes
+
+**Noun completion**
+|Old behavior|New behavior|
+|---|---|
+|No file completion by default (opposite of bash)|File completion by default; use `ValidArgsFunction` with `ShellCompDirectiveNoFileComp` to turn off file completion on a per-argument basis|
+|Completion of flag names without the `-` prefix having been typed|Flag names are only completed if the user has typed the first `-`|
+`cmd.MarkZshCompPositionalArgumentFile(pos, []string{})` used to turn on file completion on a per-argument position basis|File completion for all arguments by default; `cmd.MarkZshCompPositionalArgumentFile()` is **deprecated** and silently ignored|
+|`cmd.MarkZshCompPositionalArgumentFile(pos, glob[])` used to turn on file completion **with glob filtering** on a per-argument position basis (zsh-specific)|`cmd.MarkZshCompPositionalArgumentFile()` is **deprecated** and silently ignored; use `ValidArgsFunction` with `ShellCompDirectiveFilterFileExt` for file **extension** filtering (not full glob filtering)|
+|`cmd.MarkZshCompPositionalArgumentWords(pos, words[])` used to provide completion choices on a per-argument position basis (zsh-specific)|`cmd.MarkZshCompPositionalArgumentWords()` is **deprecated** and silently ignored; use `ValidArgsFunction` to achieve the same behavior|
+
+**Flag-value completion**
+
+|Old behavior|New behavior|
+|---|---|
+|No file completion by default (opposite of bash)|File completion by default; use `RegisterFlagCompletionFunc()` with `ShellCompDirectiveNoFileComp` to turn off file completion|
+|`cmd.MarkFlagFilename(flag, []string{})` and similar used to turn on file completion|File completion by default; `cmd.MarkFlagFilename(flag, []string{})` no longer needed in this context and silently ignored|
+|`cmd.MarkFlagFilename(flag, glob[])` used to turn on file completion **with glob filtering** (syntax of `[]string{"*.yaml", "*.yml"}` incompatible with bash)|Will continue to work, however, support for bash syntax is added and should be used instead so as to work for all shells (`[]string{"yaml", "yml"}`)|
+|`cmd.MarkFlagDirname(flag)` only completes directories (zsh-specific)|Has been added for all shells|
+|Completion of a flag name does not repeat, unless flag is of type `*Array` or `*Slice` (not supported by bash)|Retained for `zsh` and added to `fish`|
+|Completion of a flag name does not provide the `=` form (unlike bash)|Retained for `zsh` and added to `fish`|
+
+**Improvements**
+
+* Custom completion support (`ValidArgsFunction` and `RegisterFlagCompletionFunc()`)
+* File completion by default if no other completions found
+* Handling of required flags
+* File extension filtering no longer mutually exclusive with bash usage
+* Completion of directory names *within* another directory
+* Support for `=` form of flags

+There are helper functions available to get the value stored in a Flag if you have a FlagSet but find

If you have a pflag.FlagSet with a flag called 'flagname' of type int you
can use GetInt() to get the int value. But notice that 'flagname' must exist

+# The plan9 package provides access to the raw system call
+# interface of the underlying operating system. Porting Go to

+# much of the process. The auto-generated files have names

+# This script runs or (given -n) prints suggested commands to generate z files

+# This script is documentation more than anything else.

+# * asm_${GOOS}_${GOARCH}.s
+#
+# This hand-written assembly file implements system call dispatch.
+# There are three entry points:
+#
+# func Syscall(trap, a1, a2, a3 uintptr) (r1, r2, err uintptr);
+# func Syscall6(trap, a1, a2, a3, a4, a5, a6 uintptr) (r1, r2, err uintptr);
+# func RawSyscall(trap, a1, a2, a3 uintptr) (r1, r2, err uintptr);
+#
+# The first and second are the standard ones; they differ only in
+# how many arguments can be passed to the kernel.
+# The third is for low-level use by the ForkExec wrapper;
+# unlike the first two, it does not call into the scheduler to
+# let it know that a system call is running.
+#
+# * syscall_${GOOS}.go
+#
+# This hand-written Go file implements system calls that need
+# special handling and lists "//sys" comments giving prototypes
+# for ones that can be auto-generated. Mksyscall reads those
+# comments to generate the stubs.
+#
+# * syscall_${GOOS}_${GOARCH}.go
+#
+# Same as syscall_${GOOS}.go except that it contains code specific
+# to ${GOOS} on one particular architecture.
+#
+# * types_${GOOS}.c
+#
+# This hand-written C file includes standard C headers and then
+# creates typedef or enum names beginning with a dollar sign
+# (use of $ in variable names is a gcc extension). The hardest
+# part about preparing this file is figuring out which headers to
+# include and which symbols need to be #defined to get the
+# actual data structures that pass through to the kernel system calls.
+# Some C libraries present alternate versions for binary compatibility
+# and translate them on the way in and out of system calls, but
+# there is almost always a #define that can get the real ones.
+# See types_darwin.c and types_linux.c for examples.
+#
+# * zerror_${GOOS}_${GOARCH}.go
+#
+# This machine-generated file defines the system's error numbers,
+# error strings, and signal numbers. The generator is "mkerrors.sh".
