BUG: external links empty entries

[jorisvandenbossche]

In the pandas docs we get something like:

This is a strange issue. So if the external_links config option is an empty list (the default), then it actually iterates twice but without text/url.

Even when adding something like {% if theme_external_links|length > 0 %} around it, it passes that check. So somehow the empty list becomes non-empty.

[jorisvandenbossche]

Apparently you can solve this by explicitly putting this config option in conf.py:

html_theme_options = {
    "external_links": [],
    ...
}

but why the default external_links = [] in theme.conf doesn't work, no idea.

Ah I think the issue is with Sphinx reading in the default configuration as a two-item list of names: "[" and "]".

Ah, good find :)
