tree-sitter-c3

This is a complete implementation of the current C3 grammar for tree-sitter, usable for syntax highlighting, indentation, folding, code analysis, header/doc generation, and more.

The latest version supports C3 0.6.3 and is not compatible with C3 < 0.6.0.

Playground

Check out the tree-sitter-c3 playground here: https://c3lang.github.io/tree-sitter-c3/

Notes

• This is in some cases a less strict version of the "true" grammar.
• Tree structure and node naming is still subject to change.

1. Install the nvim-treesitter plugin
2. Add the following to your init.lua:

vim.filetype.add({
  extension = {
    c3 = "c3",
    c3i = "c3",
    c3t = "c3",
  },
})

local parser_config = require "nvim-treesitter.parsers".get_parser_configs()
parser_config.c3 = {
  install_info = {
    url = "https://github.com/c3lang/tree-sitter-c3",
    files = {"src/parser.c", "src/scanner.c"},
    branch = "main",
  },
}

3. Run :TSInstall c3
4. Follow the steps for adding queries to install queries/highlights.scm.
   For example, copy tree-sitter-c3/queries/* to ~/.config/nvim/queries/c3/ (replace ~/.config/nvim with your runtime path), such that you end up with the highlights file at ~/.config/nvim/queries/c3/highlights.scm.
