Example

Installation

Neovim

Neovim users can use the nvim-treesitter plugin to install the grammar.

Using Lazy.nvim package manager

1. Add the following to your Lua configuration:

   return {
     "nvim-treesitter/nvim-treesitter",
     opts = {
         ensure_installed = {
             "wit",
         }
     }
   }

Manual Installation

1. Add the following to your init.lua:

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

2. Clone the repo

3. Ensure you have just installed

4. Then run just install-local from the root of the repo; this will copy the queries into the directory used by Neovim

5. Then in Neovim run TSInstall wit

6. And you should enjoy the syntax highlighting! Please let me know if this works for you 😊
