Ember-specific YUIDoc doc block generator
In your .vimrc,
Plug 'kidonchu/yember'
By default, the key mapping to generate the doc block is
nmap <F2> <Plug>GenerateYuiDocBlock
In order to use custom key mapping, replace <F2> with any key you want and add the following to your .vimrc.
let g:yember_no_mappings = 0
In order to generate a doc block, the cursor should be on the line with the code you want to generate the doc block with.
