minimize python source code
Project description
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"""
