tree-sitter-ca65

tree-sitter-ca65 is a tree-sitter grammar for ca65 macro assembly. This project aims to provide a robust and accurate parser for 6502 assembly, enabling syntax highlighting, code navigation, and other code analysis features.

Project Status

This project is a work in progress and is subject to change. The parser is currently under development and has not been submitted to be included in the official nvim-treesitter list. Therefore, it needs to be manually configured and installed.

Installation

To install the trunk version of the tree-sitter-ca65 grammar in Neovim, you need to configure nvim-treesitter by adding the following configuration to your init.lua file:

local parsers = require("nvim-treesitter.parsers").get_parser_configs()

parsers.ca65 = {
  install_info = {
    url = "https://github.com/babasbot/tree-sitter-ca65",
    files = {
      "src/parser.c",
    },
    branch = "main",
  },
  filetype = "asm",
  maintainers = {
    "@babasbot",
  },
}

Start nvim and run :TSInstall ca65.

By default, the :TSInstall command does not copy query files from the grammar repository. You must manually add the query files to your local nvim-treesitter configuration.

Copy the contents of the queries/ca65 directory into your local Neovim configuration directory:

~/.config/nvim/queries/ca65
