White underline visible in documentation code blocks due to Sphinx Theme

[polyzen]

I see the docs are generated with quite an old version of Sphinx, maybe this has been fixed since then. If so, code blocks should probably all be made to use .. code-block.

You mean the docs on https://urlwatch.readthedocs.io/en/latest/ or the ones that one can build locally?

The deployed docs

eg. https://urlwatch.readthedocs.io/en/latest/advanced.html#setting-the-content-width-for-html2text-lynx-method

Looks okay from here:

With this source:

.. code-block:: yaml

   url: http://example.com/longlines.html
   filter:
     - html2text:
         method: lynx
         width: 400

Which browser/settings are you using?

Or do you mean the whitespace underline?

This could be a pygments/theme:

• Whitespace in code receives underline for some themes, which can be confused with a _ character pygments/pygments#2020
• Remove underline from whitespace sphinx-doc/alabaster#188

If this is the issue, maybe filing a bug over at https://github.com/readthedocs/readthedocs.org/issues might be the way to go?

One thing that might help is going with a newer Ubuntu and Python version, tried this here: 07e000f

Not sure, but newer Ubuntu might still be on the same Sphinx version :p Tested on latest Sphinx, but the issue was still there.

sphinx-doc/alabaster#188 fixed the issue, rebased and created a new PR: sphinx-doc/alabaster#202

Not sure if https://github.com/readthedocs/sphinx_rtd_theme also needs to be updated?

Haven't checked yet. If you're considering changing themes, Furo is also quite nice and well maintained.
