#13 tab width of source code in html output

[Jürgen Urner]

Tried my best to brew a patch to
add a new commandline and config setting
"src_code_tab_width" that lets the user
specify the number of spaces that replace a
tab in source code listings.

cli.py --src-code-tab-width 4

[epydoc]
src-code-tab-width=4

Default tab width is 8.

I'm Pretty new to patching, so any comments on
the patch?

The Python Language Reference explicitly describes how tabs are expanded to spaces:

http://docs.python.org/ref/indentation.html

Given that, I feel a little uneasy about adding this option. But I do know that some people use one-tab-per-indent, and that gets very wide if those tabs get expanded to 8 characters, so I guess I'll go ahead and add the option anyway.

Added in svn revision 1674.

(comments on the patch -- it was relatively clean & well-formatted. It had a minor bug -- you named the command-line option with underscores, even though all of epydoc's other command-line options (and your example) use dashes -- but that was easy enough to catch & fix. Thanks for contributing!)

o need to feel uneasy.

http://docs.python.org/ref/indentation.html only describes
how whitespace is evaluated.

Encouraged is 4 spaces per indentation level. 8 is just
some default for string.expandtabs().
