Re: On a Guile-based Build-Tool complimenting Guix

I was thinking this the other day!, was wondering about how useful a guile interface to meson would be.

After all, our goal is to make deployment, and building both more declarative and away from the all-too-familiar “dependency hell”.

Since we already have build-system, instead of executing make (or whatever other tool) commands from it, we could modify it to itself have all those things that a Makefile would have.

I haven’t thought through this clearly, but even if this doesn’t work, the main idea I’d like to propose is to fully replace existing build-tools by making a new Guile build tool to work alongside Guix.

This package definition can then be used in `guix build -f package.scm` to result in a fully transactional building process that focuses not on getting out of dependency hell, but just declaring your config right. And all of this without having to learn yet another build tool that might disappear, and of course, without leaving the comfortable world of Lisp (Scheme).

I couldn’t find if that has progressed towards anything, nor could find anything in the mailing list. I did see Pjotr volunteering to mentor for it, I’ve CC-ed them to see if they’re still interested in such a project. Meanwhile, I’d like input from other Guix core developers on what they think of this, and if they could provide me with some leads on where to go with this.
