Based on gauteh's vim-cppman. Modified by Beomjoon Goh to be used in new tab instead of opening in vertical split and to correct syntax highlighting crash with tabline.
A plugin for using cppman from within Vim. cppman is used to lookup "C++ 98/11/14 manual pages for Linux/MacOS" through either cplusplus.com or cppreference.com.
Originally cppman uses Vim to page and syntax highlight the man page, but it is not set up to be used in buffer in an existing VIM instance. That is what this small plugin does.
This is heavily based on the existing cppman.vim which is used for the Vim pager.
The keywordprg and iskeywordsettings are automatically set for C++ and
C files. Otherwise use the same keybindings as in cppman:
Move the cursor to the keyword and hit K to lookup the keyword in a new buffer.
You can also use e.g. :Cppman iostream to lookup a keyword.
1.) Install cppman
2.) Install this plugin using your favourite plugin manager.
