README.md

Examples for Lark

Beginners

  • calc.py - A simple example of a REPL calculator
  • json_parser.py - A simple JSON parser (comes with a tutorial, see docs)
  • indented_tree.py - A demonstration of parsing indentation (“whitespace significant” language)
  • fruitflies.py - A demonstration of ambiguity
  • turtle_dsl.py - Implements a LOGO-like toy language for Python’s turtle, with interpreter.
  • lark_grammar.py + lark.g - A reference implementation of the Lark grammar (using LALR(1) + standard lexer)

Advanced

  • error_reporting_lalr.py - A demonstration of example-driven error reporting with the LALR parser
  • python_parser.py - A fully-working Python 2 & 3 parser (but not production ready yet!)
  • conf.py - Demonstrates the power of LALR’s contextual lexer on a toy configuration language
  • reconstruct_json.py - Demonstrates the experimental text-reconstruction feature
