Is there a way to build my own vim knowledge base like the help system

Question

For example:

:Kb js 
   or 
:Kb javascript  

will lead me to my own javascript page

Answer 1

Yes, you can just add additional files to ~/.vim/doc/. As long as you use Vim's help syntax (*name* for tag definitions and |name| for links), you just need to update the help database via :helptags ~/.vim/doc, and then have your knowledge base available via :help name. I personally use that for "cheat pages" for certain filetypes, and to provide summary information for complex plugins.

It should also be possible to put your knowledge base into a separate directory. Then, you would have to reimplement the :help command, probably by temporarily directing the 'tags' value to it and using :tag.
