cppman(1) C++ manual page viewer / fetcher


cppman [ OPTIONS... ] PAGE...


cppman generates C++ manual pages from cplusplus.com 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 '~/.local/share/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'.


-s SOURCE, --source=SOURCE
Select source, either 'cppreference.com' or 'cplusplus.com'. Default is 'cplusplus.com'.
-c, --cache-all
cache all available man pages from cplusplus.com to enable offline browsing
-C, --clear-cache
clear all cached files
-f KEYWORD, --find-page=KEYWORD
find man page
-o, --force-update
force cppman to update existing cache when '--cache-all' or browsing man pages that were already cached
-m MANDB, --use-mandb=MANDB
Accepts 'true' or 'false'. If true, cppman adds manpage path to mandb so that you can view C++ manpages with `man' command. The default value is 'false'.
-p PAGER, --pager=PAGER
Select pager to use, accepts 'vim' or 'less'. The default value is 'vim'.
-r, --rebuild-index
rebuild index database from cplusplus.com
-v, --version
show version information
-h, --help
show this help message and exit


All contents should be cached by the user, cppman does not contain any pre-cached contents.

Do not distribute the cached man pages without the permission of cplusplus.com.


Although I spend a lot of time checking the format, there are still pages that won't display correctly.
