|
|
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:
|
|
|
|
.. code-block:: python
|
|
|
|
>>> 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:
|
|
|
|
.. code-block:: python
|
|
|
|
>>> 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"
|
|

Installation
|
|
============
|
|
|
|
pip install parso
|
|
|
|
Future
|
|
======
|
|
|
|
- There will be better support for refactoring and comments. Stay tuned.
|
|
- There's a WIP PEP8 validator. It's however not in a good shape, yet.
|
|
|
|
Known Issues
|
|
============
|
|
|
|
- `async`/`await` are already used as keywords in Python3.6.
|
|
- `from __future__ import print_function` is not ignored.
|
|
|
|
