[feature] Emacs 29.x compatibility

[domq]

A stab at #144.

• Make symlinks from libtree-sitter-LANG.so to LANG.so (or libtree-sitter-LANG.dylib to LANG.dylib on Darwin, etc) — Based on @ymarco's work in Hacky support for treesit in Emacs core #99
• Set up treesit-extra-load-path if that variable exists

[domq]

Credits to @ymarco for the symlink approach and code.

Pros : doesn't require changing the release tarball structure (yet); tree-sitter-langs-compile-friendly

Cons: doesn't work very well (or at all) on Windows.

[domq]

Fixed by making plain old copies on Windows.

Please consider for merging, or suggest improvements?

The code looks good from a quick review, but I wanna let @ubolonton decide how we wanna proceed with supporting treesit in emacs 29.

[SKyletoft]

Has there been any discussion or progress on this?

Looks like Emacs 29.1 is approaching release now

[l2dy]

Any interest in getting this merged? Emacs 29.1 was released last year.

This looked like a good change -- I wonder why it was closed? Would love to have this great set of language grammars available for built-in emacs treesit.

[zzantares]

@domq why close this?

[domq]

@domq why close this?

Let's face it: tree-sitter is a dead project. These days one should use the merged version of it, now called treesit inside the Emacs source tree.

@domq That's kinda sad to hear. While I think/hope that the built-in treesit is the future, tree-sitter will still have value for some time if you ask me.

Most of the treesit based *-ts-mode major modes just don't seem to work as well as the original major modes for languages yet. So for most languages I still use the original major-modes with tree-sitter for improved syntax highlighting.

[meain]

The builtin treesit modes do not yet have feature parity with major modes and there is some functionality available in emacs-tree-sitter not yet available in builtin treesit. That said, it is IMO not a good idea to have two parallel tree-sitter implementations with different user-facing APIs. This will make things harder for downstream plugins that use "tree-sitter". Hopefully the builtin modes get better soon.
