Hi I would suggest taking a little time to learn about tree-sitter
- Watch this: https://www.thestrangeloop.com/2018/tree-sitter---a-new-parsing-system-for-programming-tools.html - Explore https://tree-sitter.github.io/tree-sitter/ In particular use the Playground are to see the parse tree for some code (MATLAB isn't there but several other languages are available in the playground). - Google for info on tree-sitter I'm also very new to tree-sitter, so I'm still learning it. With Emacs 30, which the matlab-ts-mode is based on, I've written a new major mode, matlab-ts-mode. Think of it as a much better matlab-mode. When you open a *.m file, run M-x matlab-ts-mode What happened with Emacs is that there was one path being taken for tree-sitter integration which is in https://emacs-tree-sitter.github.io/ and that is only valid upto Emacs 29. It should not be used with Emacs 30. In Emacs 30, tree-sitter was built-in, which is a major step forward for improved language integration into Emacs. I've been writing a guide to creation of a tree-sitter major mode in the contributing subdirectory of the Emacs-MATLAB-mode subdirectory on the matlab-ts-mode branch. The guide is missing a lot, but still should be helpful. Once I have the matlab-ts-mode done, I plan on cleaning up the guide and sending it to the Emacs developers to see if it can be put in the manual because details on how to do this are light and my guide is trying to address that. There is an excellent https://github.com/emacs-tree-sitter/tree-sitter-langs site that is for Emacs 29 and earlier, so don't install that directly with Emacs 30. For Emacs 30, you either need to build the matlab tree-sitter grammer shared library, ~/.emacs.d/tree-sitter/libtree-sitter-matlab.so or extract it from the latest release in https://github.com/emacs-tree-sitter/tree-sitter-langs. To extract the latest, 1. click the "latest" link on https://github.com/emacs-tree-sitter/tree-sitter-langs 2. Download the *.gz file 3. Open the *.gz file in Emacs 4. Look for matlab.so (or matlab.dll or matlab.dylib) 5. Save that out to ~/.emacs/tree-sitter/libtree-sitter-matlab.so (or .dll or .dylib depending on what type of system you are on). Creating the HOWTO-elpa.org would be great. Can you put it in the contributing subdirectory? Also, it would be good to do changes on the matlab-ts-mode branch so it can be merged into default easily.
