spec/examples/variables/dynamic_vars.http $ not needed

[juanMarinero]

The $ I think it should be removed.

This fails to show the baseURL in the json response

POST https://postman-echo.com/post
Content-Type: application/json

{
    "foo": 123,
    "baseURL": "{{$base_url}}"
}

This works

POST https://postman-echo.com/post
Content-Type: application/json

{
    "foo": 123,
    "baseURL": "{{base_url}}"
}

.env with just 1 line:

base_url=https://httpbin.org

Result of :Rest run:

POST https://postman-echo.com/post
HTTP/2 200

What you think?

[juanMarinero]

And why does
spec/examples/examples_spec.lua does not test variables/dynamic_vars.http ?

[gorillamoe]

I think you did not grasp what the dynamic vars are.

There is a set of always available variables which are prefixed with $.

Your example just references a normal variable. Normal variables don't have that prefix.

[juanMarinero]

Thanks @gorillamoe !

Just a further minor question, are those dynamic vars provided by rest.nvim always? Thus is next sentence true?

The $ prefix is reserved for the built-in dynamic variables that rest.nvim provides automatically, not for normal variables, like the ones I define in my .env file.

I found the dynamic vars example: https://github.com/rest-nvim/rest.nvim/blob/main/spec/examples/variables/dynamic_vars.http. Code:

### dynamic variables
POST https://reqres.in/api/users
Content-Type: application/json

{
    "userid" : "{{$uuid}}",
    "time" : "{{$timestamp}}",
    "randomValue": "{{$randomInt}}",
    "name": "morpheus",
    "job": "leader",
    "array": ["a", "b", "c"],
    "object_ugly_closing": {
        "some_key": "some_value"
}
}

Bonus. How to get a table of custom dynamic variables https://github.com/rest-nvim/rest.nvim/blob/main/doc/rest-nvim.txt

                                                               *vim.g.rest_nvim*
                                                                   *g:rest_nvim*
rest.Opts                                                            *rest.Opts*

    Fields: ~
