An Emacs major mode for editing Nix expressions, powered by the new built-in tree-sitter support in Emacs 29 and the community-maintained [[https://github.com/nix-community/tree-sitter-nix][Nix tree-sitter grammar]].
** Usage
~nix-ts-mode~ only provides syntax highlighting for now, but will eventually support other tree-sitter powered features such as sexp-movement and smart indenting. After installing, enable the mode for Nix files like so:
(require 'nix-ts-mode)
(add-to-list 'auto-mode-alist '("\\.nix\\'" . nix-ts-mode))Or with ~use-package~:
(use-package nix-ts-mode
:mode "\\.nix\\'")
