pysource-minimize

If you build a linter, formatter or any other tool which has to analyse python source code you might end up searching bugs in pretty large input files.

pysource_minimize is able to remove everything from the python source which is not related to the problem.

CLI

You can use pysource-minimize from the command line like follow:

pysource-minimize --file bug.py --track "Assertion" -- python bug.py

This will run python bug.py and try to find the string "Assertion" in the output. The --file bug.py gets minimized as long as "Assertion" is part of the output of the command.

[!WARNING] Be careful when you execute code which gets minimized. It might be that some combination of the code you minimize erases your hard drive or does other unintended things.

API

Example:

>>> from pysource_minimize import minimize

>>> source = """
... def f():
...     print("bug"+"other string")
...     return 1+1
... f()
... """

>>> print(minimize(source, lambda new_source: "bug" in new_source))
"""bug"""
