Auto indent detecting tab width of 12

[beeftornado]

I have a python file that when I open, the tab size is detected to be a width of 12 and it should be 4.

Does the first line with leading space contain 12 spaces?

I did a little digging and found the cause to be an extended conditional clause that was broken up to multiple lines and occurs before any indented code blocks.

# ... comments and imports ...

if hasattr(cfg,
           'debug') and cfg.debug:
############ (12)

# ... rest of code with functions and things ...

I can fix this by just unindenting the continuation, but many coders' style is to line up the continuation with the clauses before it.

I'll have to make this a little more intelligent by searching all lines for leading spaces and using the smallest length of leading spaces. I think I was a bit naive to think scanning the whole file wasn't necessary.

Heh, it surprisingly works in most cases though.

You might be able to build off this logic http://stackoverflow.com/a/7113875/276125

Let me know if it works for you. Added a test based on your sample code, so you should be good to go.

Thanks, looks good.
