cppman - C++ manual page viewer / fetcher


cppman [ OPTIONS... ] PAGE...


cppman generates C++ manual pages from and provide a man-like interface to view man pages.

By default, cppman fetches man pages on-the-fly, by running the command 'cppman -c', all available manpages are cached, making offline browsing possible. This is also required if you want to use the system 'man' command.

Browsing man pages

cppman uses Vi Improved as a pager.
Press 'q' to leave pager. Press 'K' on an entry like 'vector::insert(3)' links you to the manual page of vector::insert, like a hyperlink.

man compatibility

cppman automatically adds '$XDG_CACHE_HOME/cppman/man' to '~/.manpath', so the cached man pages can also be viewed with 'man' command. Note that to view uncached man pages, you still need to run 'cppman'.
