Flake8 Script for BBEdit 10
#!/usr/bin/env python
"""
A quick script to install into your `Application Support/BBEdit/Scripts` folder.
This runs flake8 (requires flake8 to be installed at `/usr/local/bin` -
try ``pip install flake8``) and reformats the results
so that they show up in BBEdit's search results / error / warnings window. Then
the errors can be stepped through one at a time.
I've bound this to control-shift-l. You must save your Python file first before
running the check.
original script: https://gist.github.com/1157742
Ported to work with:
- flake8 --version: 1.4 (pyflakes: 0.5.0, pep8: 1.2)
- python --version: Python 2.7.2
BBEdit 10.1.2 (MAS)

This seems to do absolutely nothing when I run it (from the scripts menu). I even shoved in some deliberate errors, still no dice. I have the search results window already open and nothing gets printed there. Any idea what I'm doing wrong?

Never mind. You have the damn caret in the wrong place.

For those who come after, if there are any: the caret goes between the file and line location info and the error info. In this case, move the print statement that prints the caret up to just above the 'outstr = ""' line. I'd
