Is this meant to or able replace nix-build-uncached?

[ParetoOptimalDev]

overall goal: No nix builds happen if already cached, so editing Readme.md for instance would mean actions finishes in <30s.

nix-build-uncached used to allow this. Then it became nix-eval-jobs.

Now I think there might be some way in flakes that covers this functionality, at least I remember @domenkozar mentioning it somewhere.

Is it possible for nixci to support this? That was my main reason for experimenting with #28 .

So this? srid/devour-flake#9

I think? I can't say for sure if that technically maps to the end result I described above, but I'm pretty sure it does.

It looks like the creator of nix-eval-jobs also has nix-ci-build which seems very similar to nixci.

Interesting, seems to be have been created 5 days ago.

This is problematic,

For each flake attribute, a separate nix-build process is spawned.

For projects that use IFD (https://github.com/nammayatri/nammayatri) and has gazillion package outputs, this will cause repeat evaluation unnecessarily, which is what devour-flake mainly solves.

But I'll play with it to see if there's anything nixci can adopt.

If it helps I'm currently testing it out here so build time differences can be seen:

It's faster, but I think right now it may not be an accurate comparison because it's not building as much. I'm not for sure though.

Oh, related to the above I found:

https://github.com/Mic92/nix-fast-build

I asked them to compare to nixci, so I'm sure you want to look over the comparison to ensure it is accurate:

Thanks, will take a look once I get a chance. It looks like I must be missing something important, and if so that could be an opportunity to improve nixci itself.
