Unbelievable !

Testing sourcecode directive

formatter = self.options and VARIANTS[self.options.keys()[0]]

Testing another case

This will now have a line number in 'custom' since it's the default in pelican.conf, it will have nothing in default.

formatter = self.options and VARIANTS[self.options.keys()[0]]

Lovely.

Testing more sourcecode directives

 8def run(self):
      self.assert_has_content()
10    try:
          lexer = get_lexer_by_name(self.arguments[0])
12    except ValueError:
          # no lexer found - use the text one instead of an exception
14        lexer = TextLexer()
  
16    if ('linenos' in self.options and
              self.options['linenos'] not in ('table', 'inline')):
18        self.options['linenos'] = 'table'
  
20    for flag in ('nowrap', 'nobackground', 'anchorlinenos'):
          if flag in self.options:
22            self.options[flag] = True
  
24    # noclasses should already default to False, but just in case...
      formatter = HtmlFormatter(noclasses=False, **self.options)
26    parsed = highlight('\n'.join(self.content), lexer, formatter)
      return [nodes.raw('', parsed, format='html')]

Lovely.

Testing even more sourcecode directives

formatter = self.options and VARIANTS[self.options.keys()[0]]

Lovely.

Testing overriding config defaults

Even if the default is line numbers, we can override it here

formatter = self.options and VARIANTS[self.options.keys()[0]]

Lovely.
