Install grammar binaries relative to user-emacs-directory, instead of using locate-library about elisp-tree-sitter

[ubolonton]

In contrast, this package installs its non-elisp data relative to the compiled library (via load-library). This breaks when using gccemacs, because gccemacs compiles files into their own directory.

Can you provide details on how it breaks?

If you used the convention and installed into ~/.emacs.d/ , or at least allowed the user to control where the data was installed, it would fix this problem.

This is a reasonable solution for grammar binaries installed by tree-sitter-langs.el, as they are handled by the library itself. I'll make it customizable.

The dynamic module's binary installed by tree-sitter.el should be on load-path, as it is handled by the library loading mechanism. The directory that contains tree-sitter.el[cn] is currently the most sensible location. Depending on how it currently breaks on gccemacs, it may be an issue with gccemacs itself.

Sure!

When I native compile tree sitter, then run "tree-sitter-hl-mode" in, for instance, java, I get the error: tree-sitter-load: cannot find shared library for language: java.

Going into tree sitter I can see that it is /home/jacob/.emacs.d/straight/build/tree-sitter-langs/eln-x86_64-pc-linux-gnu-3fa98b4db038dd53/bin/

which obviously doesn't contain anything because the "eln" folder is a subfolder of the treesitter build directory, because native-compile-async creates a subfolder.

Thank you :)

Is this directory listed in tree-sitter-load-path? Does it contain the .so language files?

If you execute M-x tree-sitter-langs-install-grammars, where does it download the file to?

Does it work if you change the definition of tree-sitter-langs--dir to this?

(defconst tree-sitter-langs--dir
  (file-name-directory (locate-library "tree-sitter-langs.el")))

#63 introduced the custom option tree-sitter-langs-grammar-dir.
