update_mandb_path() and config.UpdateManPath

[belkka]

The function cppmap.util.update_mandb_path() is used only once in the code:

https://github.com/aitjcize/cppman/blob/841fc75bd501da448ce93750d059a16eecaac2d4/bin/cppman#L149

# from bin/cppman:
        if config.UpdateManPath:  # bool variable
            update_mandb_path()

But the function itself checks the value of config.UpdateManPath and removes some strings from the file ~/.manpath when it is False

Something is wrong. We need either

• Change the main program to enable this functionality
• Remove all occurences of environ.config.UpdateManPath from the function assuming it always is True

I'm not sure if this is related to my issue, but it certainly seems like it would be. After downloading/caching/updating my mandb, I am able to use man std::string to view its manpage, and even autocomplete man std::string<tab> in bash and zsh, but man -k std::string returns std::string: nothing appropriate. Manually exporting MANPATH with appended $HOME/.local/share/man and/or subdirectories has no effect, despite showing up in manpath's output. To be sure, man -k vector returns nothing relevant and man -k ^std returns only entries from stdio.h, while both complete the way you'd expect.

If this isn't solved or easily solvable at this time, I can come up with a workaround. For now, completions are working well enough, e.g. man s<tab>ng::string -> man std::string::string, but neither globs nor regex will, so you can't find string's constructor with man s\*ng::s\*ng, man s*ng::s*ng, apropos -r 's.*ng::s.*ng', etc.

These two problems are only very little related.

@belkka the issue you are mentioning certainly exists cppman -m false doesn't unregister the path properly. In general there seems to be an issue with the folders. Everything should be located in ~/.cache/cppman and not ~/.local/share/man Besides removing an entry from ~/.manpath also the removal of the man3 is missing (which would not be necessary if it is stored in .cache/cppman).

@jep-dev The problem that I see here is that mandb doesn't create indexed entries for ~/.local/share/man. To solve this issue there needs to be an MANDB_MAP entry in .manpath. Like this:

MANDATORY_MANPATH       /home/sgssgene/.local/share/man
MANDB_MAP               /home/sgssgene/.local/share/man  /home/sgssgene/.local/share/manindex
