Some novice fibs questions

[hoglet67]

Hi Floooh,

I'm trying to update the AtoMMC changes I did (in back 2019) to your chips/chips-test Atom emulator to run against your latest code base.

(these changes are currently parked in my chips/chips-test fork on a branch called atommc_2019)

I have a couple of fibs questions, if you have a moment.

1. How to I pass configuration parameters down to the emscripten compiler?

In the old fips world, this was done in:

fips-files/configs/wasm-ninja-debug.yml
fips-files/configs/wasm-ninja-release.yml

I'm looking for the equivalent of:

FIPS_EMSCRIPTEN_USE_FS: ON
FIPS_EMSCRIPTEN_TOTAL_MEMORY: 67108864
FIPS_EMSCRIPTEN_USE_CLOSURE: ON

2. Is there any way to make an import reference a specific branch?

    c.addImport({
        name: 'chips',
        url: 'https://github.com/hoglet67/chips',
    });

I'd like to use atommc_2026 rather than having to do all my work on master.

3. Is there any way to make an import reference a local git repository, so I don't need to commit before I can build?

Specifically, I'd like to just point the chips import at ../chips and check this out manually.

Many thanks,

Dave

How to I pass configuration parameters down to the emscripten compiler?

This works now with 'import options'. E.g. when you run fibs list imports you should see this listed under platforms:

platforms: https://github.com/floooh/fibs-platforms
  emscripten.ts: emscripten platform support
    emscripten:
      initialMemory?: number - initial wasm memory in bytes (default: 32 MB)
      allowMemoryGrowth?: boolean - enable/disable wasm memory growth (default: true)
      stackSize?: number - wasm stack size in bytes (default: 512 KB)
      useEmmalloc?: boolean - enable/disable minimal emmalloc allocator (default: true)
      useFilesystem?: boolean - enable/disable emscripten filesystem layer (default: false)
      useLTO?: boolean - enable/disable LTO in release mode (default: true)
      useClosure?: boolean - enable/disable closure optimization in release mode (default: true)
      useMinimalShellFile?: boolean - use minimal shell.html file (default: true)

...used in the configure() function like this:

https://github.com/floooh/fibs-sokol-test/blob/2bb206083c4e749d99a7f89039cffabe14a2ea63/fibs.ts#L4-L11

Is there any way to make an import reference a specific branch?

Yes, via 'ref' in the import specification, this can be a branch name, tag name, or a specific commit-sha, for instance:

    c.addImport({
        name: 'chips',
        url: 'https://github.com/hoglet67/chips',
        ref: 'atommc_2026',
    });

Is there any way to make an import reference a local git repository, so I don't need to commit before I can build?

Yes :) It's called 'linking an import' (to a local directory).

E.g. to link to a git checkout at ../chips:

./fibs link chips ../chips
    linked import 'chips' to '/Users/floh/projects/chips'

...now when you run `./fibs list imports' you should see something like this:

./fibs list imports
...
chips: link => /Users/floh/projects/chips
...

...to 'unlink' (e.g. use the regular import under the .fibs/ directory just run ./fibs unlink chips.

The link-settings are stored in .fibs/links.json, so the link-association is also gone when you accidentially delete the .fibs subdir (or run ./fibs reset).

Hope this helps! Let me know when you run into any problems :)

Thanks for that. it helped a lot.

I've re-integrated the AtoMMC work I did in 2019, and also some improvement to the keyboard handling:
hoglet67/chips@55172088

The improves the handling of shift, control, repeat, cap lock, copy, as well as fixing a couple of minor ommissions from the key map. See the comments in the above commit.

All of this is parked in a branch called atommc_2-26 in my fork.

There is a version deployed here:
https://hoglet67.github.io/atom-ui-new/index.html?autoboot=true

(The autoboot flag causes AtoMMC to run *MENU on BREAK, shift will reverse this)

Anyway, again may thanks for all your excellent work on this emulation platform over the years.
