Molokai is a Vim port of the monokai theme for TextMate originally created by Wimer Hazenberg.

By default, it has a dark gray background based on the version created by Hamish Stuart Macpherson for the E editor.

256-Color terminals are also supported, though there are some differences with the Gui version. Only the dark gray background style is supported on terminal vim at this time.

Copy the file on your .vim/colors and .vim/syntaxs folder.

If you prefer the scheme to match the original monokai background color, put this in your .vimrc file:

let g:molokai_original = 1

There is also an alternative scheme under development for color terminals which attempts to bring the 256 color version as close as possible to the the default (dark) GUI version. To access, add this to your .vimrc:

let g:rehash256 = 1

If you prefer the scheme to highlight the syntax, put this in your .vimrc file:

let g:molokai_original = 1

You can also use the nine2/vim-custom-syntax plugin to customize the extended syntax highlighting，it is very beautiful！
