tree-sitter-commonlisp

WIP. Goal is to have a better syntax highlighting for Neovim and some semantic refactoring https://github.com/nvim-treesitter/nvim-treesitter-refactor/.

All praise goes to https://github.com/sogaiu/tree-sitter-clojure which is extended by this grammar.

TODOs:

• support number literals that are different from clojure (e.g. .9)

Macros with special respresentation in syntax tree (when written with lowercase letters):

• defun and friends (e.g. defmethod)
• loop macro

This grammar is used in https://github.com/Wilfred/difftastic to generate syntax-ware diffs for Common Lisp.

Usage

• C/C++

  • compilation run make (optional make install)
  • Follow the Guide on using tree-sitter parsers
  • set tree_sitter_commonlisp() as language on your Tree-Sitter parser from tree_sitter_commonlisp.h

  ts_parser_set_language(parser, tree_sitter_commonlisp());

• Python (pip install tree-sitter-commonlisp tree-sitter)

  tree-sitter-commonlisp/bindings/python/tests/test_import.py

  Lines 15 to 23 in 4d2a224

  	lang = tree_sitter.Language(tree_sitter_commonlisp.language())
  	parser = tree_sitter.Parser(lang)
  	tree = parser.parse(
  	bytes(
  	"""
  	(+ 1 1)
  	""",
  	"utf8"
  	)

• Rust cargo add tree-sitter tree-sitter-grammars

  tree-sitter-commonlisp/bindings/rust/lib.rs

  Lines 47 to 50 in 4d2a224

  	let mut parser = tree_sitter::Parser::new();
  	parser
  	.set_language(&LANGUAGE_COMMONLISP.into())
  	.expect("Error loading commonlisp language");
