Hi,

First of all thank you for your work on sway and meson!

As I know it's not enough.  Intead you could use:
--8<---------------cut here---------------start------------->8---
~/repos/guix/pre-inst-env guix build sway
--8<---------------cut here---------------end--------------->8---

Also, you could run a “make -j3” command before ‘./pre-inst-env’ to spot
some compilations errors after changing package recipes.

Did you set GUIX_PACKAGE_PATH?  You could check with:
--8<---------------cut here---------------start------------->8---
./pre-inst-env env | grep GUIX_PACKAGE_PATH
--8<---------------cut here---------------end--------------->8---
which should show GUIX_PACKAGE_PATH= or show nothing.

It's OK to use ‘git-fetch’, and we switch to it in favour of ‘url-fetch’
because of GitHub could regenerate tarballs.  But I think thats probably
not a ‘meson’ case.

Release tarball could differ from Git repository.  Did you succeed to
build the ‘git-fetch’ way (via ‘pre-inst-env’)?

Why do you comment ‘meson-for-build’?  First of all don't comment things
which should be removed, because of Git.  ;-) And it's used by:
--8<---------------cut here---------------start------------->8---
oleg@guixsd ~/src/guix-master$ grep -RF meson-for-build ~/src/guix-master | grep '.scm'
/home/oleg/src/guix-master/guix/build-system/meson.scm:    (module-ref module 'meson-for-build)))
--8<---------------cut here---------------end--------------->8---

That url should be a string:
--8<---------------cut here---------------start------------->8---
error: https://gitlab.freedesktop.org/mesa/mesa/: unbound variable
hint: Did you forget a `use-modules' form?
--8<---------------cut here---------------end--------------->8---

I think we should use hard-coded "mesa-" as in source urls.

Same thing about commenting unused code.  Just remove it.

Everything else looks OK, but could you split this big patch by “patch
per package upgrade”?

Thanks,
Oleg.
