How to tell tree-sitter to look for libtree-sitter-go-mod.so instead of libtree-sitter-gomod.so?

How to tell tree-sitter to look for libtree-sitter-go-mod.so instead of libtree-sitter-gomod.so?

[Pankaj Jangid]

I am on emacs-29 branch.

I have following settings for go in the ~/.emacs.d/init.el,

#+begin_src elisp
  (setq treesit-language-source-alist
	'((go . ("https://github.com/tree-sitter/tree-sitter-go.git"))
	  (go-mod . ("https://github.com/camdencheek/tree-sitter-gomod.git"))))
  (add-to-list 'auto-mode-alist
	       `("\\.go\\'" . go-ts-mode))
  (add-to-list 'auto-mode-alist
	       `("\\go.mod\\'" . go-mod-ts-mode))
#+end_src

whenever I load .go or go.mod files, I get this error,

--8<---------------cut here---------------start------------->8---
⛔ Warning (treesit): Cannot activate tree-sitter, because language grammar for gomod is unavailable (not-found): (libtree-sitter-gomod libtree-sitter-gomod.0 libtree-sitter-gomod.0.0 libtree-sitter-gomod.so libtree-sitter-gomod.so.0 libtree-sitter-gomod.so.0.0) No such file or directory
--8<---------------cut here---------------end--------------->8---

Emacs is looking for libtree-sitter-gomod.so, but in fact the library's
name is libtree-sitter-go-mod.so. Where can I tell tree-sitter to look
for the appropriate file.

Or is this a bug?

You need to use the symbol 'gomod' and not 'go-mod' in
treesit-language-source-alist.

Here is your fixed init.el:

#+begin_src emacs-lisp
(setq treesit-language-source-alist
  	  '((go . ("https://github.com/tree-sitter/tree-sitter-go.git"))
  		(gomod . ("https://github.com/camdencheek/tree-sitter-gomod.git"))))
(add-to-list 'auto-mode-alist
  			 `("\\.go\\'" . go-ts-mode))
(add-to-list 'auto-mode-alist
  			 `("\\go.mod\\'" . go-mod-ts-mode))
#+end_src

Thanks. It worked.
