Using lazy:

return {
    "bbfh-dev/tree-sitter-mcfunction",
    config = function()
        local parser_config = require("nvim-treesitter.parsers").get_parser_configs()
        parser_config.mcfunction = {
            install_info = {
                url = "https://github.com/bbfh-dev/tree-sitter-mcfunction",
                files = { "src/parser.c" },
                branch = "main",
                generate_requires_npm = false, -- stand-alone parser without npm dependencies
                requires_generate_from_grammar = false, -- folder contains pre-generated src/parser.c
                queries = "queries/mcfunction",
            },
        }

        vim.filetype.add({
            extension = {
                mcfunction = "mcfunction",
            },
        })
    end,
}

Refer to your editor's documentation on custom tree-sitter grammars.

I do not use other text editors, but I will happily accept contributions for plugins/add-ons/extensions that enable this grammar in a different editor.

1 Macros

This grammar accepts $(macro)-s in many common places. However, some $(macro) tricks simply cannot be properly handled and can lead to errors.

2 Testing

[!IMPORTANT] Quantity ≠ quality. I used all projects I could scramble on my machine, but that does not mean that all possible syntax is covered.

Alongside tree-sitter tests, the grammar was tested on at least 19,293 files (~146,314 lines) worth of mcfunction code.
