Sphinx (documentation tool): set tab width in output

Question

How do you set tab width in HTML output of Sphinx code snippets highlighted by Pygments? By default it is the annoying 8, but I want 4. Did not find a word about this setting in Sphinx conf.py.

Answer 1

You will need to write a Sphinx Extension. Add your custom Lexer, and apply it with VisibleWhitespaceFilter.
