tree-sitter-mcore

Miking MCore grammar for tree-sitter.

The grammar is based on the grammar for the Miking boot interpreter written using Ocamllex and Menhir.

Install

If you want to generate source files from the grammar use the tree-sitter cli to run tree-sitter generate. Otherwise use those which already exist in the repo.

Run tree-sitter build which will output a mcore.so which you can use like any other tree-sitter parser.

Integrations into editors vary but here is an example config for using the parser in NeoVim using nvim-treesitter:

  { -- Highlight, edit, and navigate code
    'nvim-treesitter/nvim-treesitter',
    build = ':TSUpdate',
    opts = {
      ensure_installed = {},
      auto_install = true,
      highlight = {
        enable = true,
      },
      indent = { enable = true },
    },
    config = function(_, opts)
      -- [[ Configure Treesitter ]]
      local parser_config = require('nvim-treesitter.parsers').get_parser_configs()
      parser_config.mcore = {
        install_info = {
          url = 'https://github.com/wmuth/tree-sitter-mcore',
          branch = 'main',
          files = { 'src/parser.c', 'src/scanner.c' },
          requires_generate_from_grammar = false,
        },
        filetype = 'mcore',
      }

      vim.filetype.add {
        extension = {
          mc = 'mcore',
        },
      }

      require('nvim-treesitter.configs').setup(opts)
    end,
  },

Todo

• Improved tests, currently can parse all .mc files in the stdlib of miking without errors ( tree-sitter parse /path/to/miking/src/stdlib/**/*.mc | rg 'ERROR' )
• Improved documentation
• Improved highlighting
