How to launch own 2to3 fixer?

Question

I wrote own fixer, how can i run it? I don't find obvious way to do this.

Only this:

> cd /usr/lib/python2.7/lib2to3/fixes/
> ln -s path/to/my_fixer.py

And then run it:

> cd path/to/project
> 2to3 -f my_fixer .

Answer 1

I got it! (file: my2to3)

#!/usr/bin/env python2.7
import sys
from lib2to3.main import main

sys.path.append('path/to/my_own_package')
sys.exit(main('my_own_package.contained_fixers'))

And then run it:

> ./my2to3 -f my_fixer -w project
