python3-parso

Python parser that supports error recovery - Python 3.X

Description

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.

A simple example:

>>> import parso

>>> module = parso.parse('hello + 1', version="3.6")

>>> expr = module.children[0]

>>> expr

PythonNode(arith_expr, [<Name: hello@1,0>, <Operator: +>, <Number: 1>])

>>> print(expr.get_code())

hello + 1

>>> name = expr.children[0]

>>> name

<Name: hello@1,0>

>>> 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"
