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, [, , ]) >>> 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: .. 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" Resources ========= - `Testing `_ - `PyPI `_ - `Docs `_ - Uses `semantic versioning `_ 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. Acknowledgements ================ - Guido van Rossum (@gvanrossum) for creating the parser generator pgen2 (originally used in lib2to3). - `Salome Schneider `_ for the extremely awesome parso logo. .. _jedi: https://github.com/davidhalter/jedi .. :changelog: Changelog --------- 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. 0.6.2 (2020-02-27) ++++++++++++++++++ - Bugfixes - Add Grammar.refactor (might still be subject to change until 0.7.0) 0.6.1 (2020-02-03) ++++++++++++++++++ - Add ``parso.normalizer.Issue.end_pos`` to make it possible to know where an issue ends 0.6.0 (2020-01-26) ++++++++++++++++++ - Dropped Python 2.6/Python 3.3 support - del_stmt names are now considered as a definition (for ``name.is_definition()``) - Bugfixes 0.5.2 (2019-12-15) ++++++++++++++++++ - Add include_setitem to get_definition/is_definition and get_defined_names (#66) - Fix named expression error listing (#89, #90) - Fix some f-string tokenizer issues (#93) 0.5.1 (2019-07-13) ++++++++++++++++++ - Fix: Some unicode identifiers were not correctly tokenized - Fix: Line continuations in f-strings are now working 0.5.0 (2019-06-20) ++++++++++++++++++ - **Breaking Change** comp_for is now called sync_comp_for for all Python versions to be compatible with the Python 3.8 Grammar - Added .pyi stubs for a lot of the parso API - Small FileIO changes 0.4.0 (2019-04-05) ++++++++++++++++++ - Python 3.8 support - FileIO support, it's now possible to use abstract file IO, support is alpha 0.3.4 (2019-02-13) +++++++++++++++++++ - Fix an f-string tokenizer error 0.3.3 (2019-02-06) +++++++++++++++++++ - Fix async errors in the diff parser - A fix in iter_errors - This is a very small bugfix release 0.3.2 (2019-01-24) +++++++++++++++++++ - 20+ bugfixes in the diff parser and 3 in the tokenizer - A fuzzer for the diff parser, to give confidence that the diff parser is in a good shape. - Some bugfixes for f-string 0.3.1 (2018-07-09) +++++++++++++++++++ - Bugfixes in the diff parser and keyword-only arguments 0.3.0 (2018-06-30) +++++++++++++++++++ - Rewrote the pgen2 parser generator. 0.2.1 (2018-05-21) +++++++++++++++++++ - A bugfix for the diff parser. - Grammar files can now be loaded from a specific path. 0.2.0 (2018-04-15) +++++++++++++++++++ - f-strings are now parsed as a part of the normal Python grammar. This makes it way easier to deal with them. 0.1.1 (2017-11-05) +++++++++++++++++++ - Fixed a few bugs in the caching layer - Added support for Python 3.7 0.1.0 (2017-09-04) +++++++++++++++++++ - Pulling the library out of Jedi. Some APIs will definitely change.
