Re exception: bogus escape: '\\2' (Javascript)

[ChristopherRabotin]

Input file is called "main.js" (so nothing spectacular).

Here's the traceback (I tried to correct the output from Powershell):

Hey Christopher,

Sorry to take so long to get to this. Could you send over main.js and I can take a look?

[ChristopherRabotin]

Hi Scott,

No problem. The code is here: http://pastebin.ca/UATjx4IX . The password is code2flow. My code uses classes, could that be a limitation of code2flow?

If you need a helping hand, I can see what I can do, I have about ten years of on and off experience with Python.

Couldn't seem to reproduce the error. I run it like:
code2flow main.js
and it produces out.png. Were there some other variables or maybe it was a
different version of the file?

The issue was actually the (stupid) backslashes used in windows. In fact, I copied the source I wanted to graph directly into the folder where code2flow is. That worked without a problem. Thanks for the support.

Awesome! Glad that worked. Thanks for the bug report!

Ugh. Just bit me trying to use code2flow with python3.4.2. Windows paths ugh.
Thanks ChristopherRabotin.
