Better Rainbow Parentheses

Forked from https://github.com/kien/rainbow_parentheses.vim since that now appears to be unmaintained.

Options:

The colours used; the outermost pair is coloured with the last colour in the list, the next-outermost with the second-last colour, etc. The first element of each entry is the terminal colour, the second element is the GUI (gvim) colour.

let g:rbpt_colorpairs = [
    \ ['red',         'RoyalBlue3'],
    \ ['brown',       'SeaGreen3'],
    \ ['blue',        'DarkOrchid3'],
    \ ['gray',        'firebrick3'],
    \ ['green',       'RoyalBlue3'],
    \ ['magenta',     'SeaGreen3'],
    \ ['cyan',        'DarkOrchid3'],
    \ ['darkred',     'firebrick3'],
    \ ['brown',       'RoyalBlue3'],
    \ ['darkblue',    'DarkOrchid3'],
    \ ['gray',        'firebrick3'],
    \ ['darkgreen',   'RoyalBlue3'],
    \ ['darkmagenta', 'SeaGreen3'],
    \ ['darkcyan',    'DarkOrchid3'],
    \ ['red',         'firebrick3'],
    \ ]

How deep to colour (repeating the colour list if necessary) before giving up; limited for performance reasons.

let g:rbpt_max = 15

let g:rbpt_loadcmd_toggle = 0

Also bold parenthese to make the colours stand out more.

let g:bold_parentheses = 1      " Default on

Commands:

:RainbowParenthesesToggle       " Toggle it on/off
:RainbowParenthesesLoadRound    " (), the default when toggling
:RainbowParenthesesLoadSquare   " []
:RainbowParenthesesLoadBraces   " {}
:RainbowParenthesesLoadChevrons " <>

Always On:
