pygrep 0.3

Find python identifiers

Ever tried to refactor some python code and trying to find out where you're code is used?

find . -name \*.py | xargs grep foo.bar

is kinda nice, but it'll find imports, comments, and whatnot.

Meet pygrep, it allows you to find all references to your code,

pygrep foo.bar some/dir other/stuff.py

That will show you some output like

file.py(Class.function):lineno foo.bar.full.identifier

In file.py, there's a reference to foo.bar.full.identifier in the method function in class Class.

Supported

At this point, pygrep resolves

from foo import bar

and

from foo import bar as baz

Example

Given this python file foo.py

from mymod.bar import stuff as a
class A:
    def m(self):
        b = a.mod.method()

all the following commands

pygrep mymod foo.py
pygrep mymod.bar foo.py
pygrep mymod.bar.mod foo.py
pygrep mymod.bar.mod.method foo.py

will return

foo.py(A.m):4 mymod.bar.mod.method
