Topic: overwrite platform URL from command line?

Jasper Woudenberg (Jan 07 2025 at 22:12):

I've realized that being able to overwrite the platform URL from the command line would be a nice quality-of-life improvement for platform development.

I've an example in my Roc platform, and I'd like to build/run it against different platforms:

• In code, comitted, ideally the URL refers to the latest released version of the platform, so anyone trying to learn can copy/paste the example and try it out themselves.
• While developing I'd like the platform to be a relative path to wherever my build system puts the compiled platform bundle (for my Zig platform I've picked zig-out/platform).
• In CI, during a release, I'd love to run the example against the compiled <hash>.tar.br bundle, as a smoke-test.

Quite possible I'm missing a security (or other) angle though!

Yeah, I'd like this too, being able to use tar.br with a path, not only in a URL.
@Richard Feldman probably has the best understanding of the security implications

I think it's fine if it's a cli flag!

I'd suggest allowing substitutions, e.g. "any time you encounter a package with this path or URL, replace it with this other path or URL"

this way you can also use it to test out a bugfix of an indirect dependency

@Jasper Woudenberg can you make a tracking issue for this please?

Sure thing, here it is: https://github.com/roc-lang/roc/issues/7494

overwrite the platform URL from the command line

This may be the first modification of the ingested Roc file, I wonder if that will create problems :thinking:
