|
|
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="3.9")
|
|
>>> 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"
|
|

|
|
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.
|
|
|
|

|
++++++++++++++++++
|
|
|
|
- Add basic support for Python 3.11 and 3.12

|
- Various small bugfixes
|
|
|
|
0.8.0 (2020-08-05)
|
|
++++++++++++++++++
|
|
|
|
- Dropped Support for Python 2.7, 3.4, 3.5
|
|
- It's possible to use ``pathlib.Path`` objects now in the API
|
|
- The stubs are gone, we are now using annotations
|
|
- ``namedexpr_test`` nodes are now a proper class called ``NamedExpr``
|
|
- A lot of smaller refactorings
|
|
|
|
0.7.1 (2020-07-24)
|
|
++++++++++++++++++
|
|
|
|
- Fixed a couple of smaller bugs (mostly syntax error detection in
|
|
``Grammar.iter_errors``)
|
|
|
|
This is going to be the last release that supports Python 2.7, 3.4 and 3.5.
|
|
|
|
0.7.0 (2020-04-13)
|
|
++++++++++++++++++
|
|
|
|
- Fix a lot of annoying bugs in the diff parser. The fuzzer did not find
|
|
issues anymore even after running it for more than 24 hours (500k tests).
|
|
- Small grammar change: suites can now contain newlines even after a newline.
|
|
This should really not matter if you don't use error recovery. It allows for
|
|
nicer error recovery.
