The question is in the title. As a use case one can imagine the situation about finding function basing on its known functionality.
I already know about Zeal which is packaged. It downloads documentation sets from Dash project. This is great but the Python versions differ from installed on system. They are usually newer.
The DevHelp application do not know about Python libraries. The search on
pydoc3 -p 8080 does not work as expected. KHelpCenter does not know about Python. The doc-central package seems to be broken for long time. dochelp shows only index from
/usr/share/doc-help and does not provide full-text search.
What else should I try to have ability for reading and searching Python documentation offline from
/usr/share/doc (and similar locations)?
My system reports that I have 467 folders there (
ls -1d /usr/share/doc/*python* | wc -l).
