We've got quite a few packages that simply copy some files from their source to the output. Examples include `debian-archive-keyring`, `0ad-data`, `gcide`, or `rofi-pass`. Those packages end up being tedious to write because we need to rely on the trivial-build-system, also known as "the least trivial of them all!" :) What about adding a "copy-build-system" which has one argument, say an `#:install-plan` that takes a list of source-destination pairs? This would drastically simplify the definition of the aforementioned packages, basically summing up dozens of boilerplate lines into an effectively trivial file mapping. If this sounds like a good idea, I'd be happy to send a patch! Cheers!That would be great!
I agree that this would be great as well. In addition to tedium, trivial-build-system can make modifications to package definitions, which I consider a really cool guix feature and a win for software freedom, more tricky. See https://lists.gnu.org/archive/html/help-guix/2019-12/msg00139.html for an issue I had with it (sorry Marius, I haven't had time to play with switching the build system of matcha-theme, but it's still on my todo list :)).
Best, Jack
