r""" Parso is a Python parser that supports error recovery and round-trip parsing for different Python versions (in multiple Python versions). Parso is also able to list multiple syntax errors in your python file. Parso has been battle-tested by jedi_. It was pulled out of jedi to be useful for other projects as well. Parso consists of a small API to parse Python and analyse the syntax tree. .. _jedi: https://github.com/davidhalter/jedi A simple example: >>> import parso >>> module = parso.parse('hello + 1', version="3.9") >>> expr = module.children[0] >>> expr PythonNode(arith_expr, [, , ]) >>> print(expr.get_code()) hello + 1 >>> name = expr.children[0] >>> name >>> name.end_pos (1, 5) >>> expr.end_pos (1, 9) To list multiple issues: >>> grammar = parso.load_grammar() >>> module = grammar.parse('foo +\nbar\ncontinue') >>> error1, error2 = grammar.iter_errors(module) >>> error1.message 'SyntaxError: invalid syntax' >>> error2.message "SyntaxError: 'continue' not properly in loop" """ from parso.parser import ParserSyntaxError from parso.grammar import Grammar, load_grammar from parso.utils import split_lines, python_bytes_to_unicode __version__ = '0.8.4' def parse(code=None, **kwargs): """ A utility function to avoid loading grammars.
