If everything goes right, you just need to add a :local t flag in treesit-range-rules. Check out the modified bision-ts-mode.el that I hacked up for an example. BTW, it’s vital that you define treesit-language-at-point-function for a multi-language mode. YuanThanks a lot! I did some tests and it's working pretty well.Awesome!It seems I spoke a bit too soon :( When I edit the buffer, sometimes there is an offset between the text and the nodes after modifying the buffer, or the syntax highlighting breaks in C code. I attached an example Bison file if needed.Thanks. I was able to reproduce this, but then can’t. I’ll keep looking into this, if you found out something new please let me know.
It may be unrelated, but I have this popping in *Messages* sometimes:Error during redisplay: (jit-lock-function 1410) signaled (treesit-load-language-error not-found ("libtree-sitter-nil" "libtree-sitter-nil.0" "libtree-sitter-nil.0.0" "libtree-sitter-nil.so" "libtree-sitter-nil.so.0" "libtree-sitter-nil.so.0.0") "No such file or directory")
I have a few issues though: - I first defined `treesit-language-at-point-function` using `treesit-node-at`. However, `treesit-node-at` itself uses `treesit-language-at-point-function` which causes an infinite recursion. So I instead used `treesit-local-parsers-at` to check if a local parser is used. Is it a good solution?No no, you should use the host langauge’s parser (bison) and see if point is in an undelimited_code_block, and return c or bison accordingly. I’m highlight this in the docstring, thanks.So I need to call `treesit-node-at` with `'bison` as the value for PARSER-OR-LANG to see in which node I am? Then I think there is a problem with `treesit-node-at`, because it always call `treesit-language-at` even if PARSER-OR-LANG is provided. I propose a fix in the attached patch.You are right. I applied a similar fix. It should be good now. Thanks!
Thanks!
