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="3.6")
|
||||
>>> 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"
