Include Static Resources in Example Project

[vbrandl]

This shows an example usage of localPatterns to include static resources in the build sandbox

Thanks for opening this PR, @vbrandl! While I do appreciate the addition, and the changes themselves do look correct to me, I don't think we should add this to either of the existing example projects. I think it's out of scope given both of their defined purposes and perhaps would be better suited to a later example with more practical use, e.g. an example use of tonic which includes external .proto schemas. Then again, that's just my thought. 😄

What do all you think, @trha @eupn @antigravityla @snawaz?

[vbrandl]

I could also create a third example repo and use https://github.com/vbrandl/cargo2nix-ructe-testcase as a base.

Also is there a better way to extend localPatterns? Currently I duplicated the default values. Maybe there is a way to append to the existing localPatterns instead of copying the default values?

[ebkalderon]

That could work, sure! We'd need to write up a suitable tutorial for it, of course, but the Rust and Nix code for it is simple enough that I could see it being a good example project. 👍

Sadly, there isn't a way to duplicate the values for localPatterns under the current design, unless we were to maybe have [ ''^(src)(/.*)?'' ''[^/]*\.(rs|toml)$'' ] be built into makePackageSet and then have localPatterns ? [], which is then concatenated to that built-in list.

[vbrandl]

I reverted the changes in the existing example project and added a third example.

I don't know enough about nix expressions yet to implement the change you proposed for makePackageSet. Do you want to make this change on the same branch or will this be a separate PR?

[ebkalderon]

I think it should be on a separate branch, since it's conceptually a different change that will need to be discussed and evaluated separately.

I'll review it as soon as I can, but I'm currently away from a computer at the moment. Please bear with me for a little bit! If someone else wants to swoop in and take this on, that'd be cool too.

[ebkalderon]

Sorry for the delay, @vbrandl. Looks good to me! 👍

Would you mind rebasing against the latest master and dropping the first few commits, including the reverts, from the PR?

[vbrandl]

I rebased against upstream master and removed the old commits.

[ebkalderon]

Thanks for the great work, @vbrandl! Looks good to me.

I'll open an issue for writing up a proper tutorial for it.
