Hello Simon,
Thanks for the input. I came across this:
https://lists.gnu.org/archive/html/guix-devel/2022-12/msg00073.html
Maybe this can be used as a foundation. I tested it locally and it works
fine, but I don't know how it needs to be altered in order to be pushed
upstream.
On that note, how would one package an emacs package that leverages
tree-sitter? I want to package https://github.com/isamert/jsdoc.el which
requires tree-sitter. I wrote a package definition where I substituted
My understanding is that I need to provide emacs with tree-sitter
support as an input for that to work. Here's a package definition I wrote:
--8<---------------cut here---------------start------------->8---
(define-public emacs-jsdoc
(let ((commit "2e7c02ff2dc422bc21c405bd90a7092c2f599630")

--8<---------------cut here---------------end--------------->8---
My understanding is that I need to provide emacs with tree-sitter
support as an input for this to work, which I did, but it'll fail with
--8<---------------cut here---------------start------------->8---
Debugger entered--Lisp error: (file-missing "Cannot open load file" "No such
file or directory" "treesit")
--8<---------------cut here---------------end--------------->8---
Maybe someone can help me here. I tried looking at other package
definitions, but I don't know if there are any emacs packages that
require tree-sitter packaged in Guix yet.
Thanks in advance.
