py3names 0.1

Discover names defined in a python file

Lists names defined in a python3 file. Pretty simple yeah.

usage

$ py3names nuclear_launch.py
os
sys
warhead
detonate
trajectory
firepower

or

$ cat nuclear_launch.py | py3names
os
sys
warhead
detonate
trajectory
firepower

so what?

It parses the code using the ast module and the traverses the resulting syntax tree for name definitions.

Currently detectable:

• global and function scope defined variables
• classes and object attributes
• function and function arguments
• for loop iteration variable names

what’s the point

I mainly needed this for the vim CodeInColor plugin
