After reading Rahul's post Emacs 31 Is Around the Corner: The Changes I'm Already Daily Driving I simplified my setup and turned on all the tree-sitter modes

(treesit-enabled-modes t)

I regretted that as soon as I opened a YAML file though. It turns out the yaml-ts-mode is rather unusable.¹ I switched back to yaml-mode and adjusted the value of treesit-enabled-modes to include what I have use for (the change):

(treesit-enabled-modes '(bash-ts-mode
                         c++-ts-mode
                         c-or-c++-ts-mode
                         c-ts-mode
                         dockerfile-ts-mode
                         go-mod-ts-mode
                         go-ts-mode
                         go-work-ts-mode
                         json-ts-mode
                         python-ts-mode
                         rust-ts-mode
                         typescript-ts-mode))

The customization of treesit-enabled-modes contains a list of all the supported modes.

I hope someone will take pity on yaml-ts-mode and make it usable soon.

When I began tinkering with my own treesitter-based mode for Haskell I failed to find a tree-sitter grammar for Cabal files so I wrote a rather rough one myself. My hope was that it could serve as a base, or motivation, for someone else to write a proper one. It took more than 2 years, but now it's finally happened!

I've switched my mode to use Curtis's grammar and I'll be archiving mine. (The change.)

Rahul's post also mentions that editable xref buffers. I had the same itch to have editable xref buffers, and I'd added a function to turn them into grep buffers to be able to edit them. I've now switched to using the built-in support, and removed the function.

At the same time I also decided to remove wgrep and instead use the builtin function for editing grep buffers.
