⚡ revital.vim ⚡

revital.vim makes vital.vim a lot faster.

How to start revital.vim

1. Execute :Vitalize --name={plugin-name} {target-dir} [{module} ...] to embed vital modules if you didn't run :Vitalize yet. See :h :Vitalize & :h Vital-usage.
2. Execute :Revitalize {target-dir}.
3. Replace vital#of('plugin-name') with vital#{plugin-name}#of().
4. The rest of usage is same as :h Vital-usage.
5. Enjoy speed!

Example

Install modules for your own plugin

Replace {pluginname} with your plugin name.

:cd $HOME/.vim/bundle/{pluginname}/
:Vitalize --name={pluginname} . Data.List
:Revitalize .

Use vital modules

let s:V = vital#{pluginname}#of()
let s:List = s:V.import('Data.List')
echo s:List.uniq([1, 1, 2, 3, 1, 2])
" => [1, 2, 3]

Some people claims the plugin using vital.vim is slow, so I guess the speed improvement might be even bigger in some environments.
