Rainbow Parentheses Improved

help you read complex code by showing diff level of parentheses in diff color !!

Description (这里有中文版)

As everyone knows, the most complex codes were composed of a mass of different kinds of parentheses(typically: lisp). This plugin will help you read these codes by showing different levels of parentheses in different colors. you can also find this plugin in www.vim.org.

What is improved ?

• no limit of parentheses levels.
• separately edit guifgs and ctermfgs (the colors used for highlighting)
• now you can design your own parentheses such as 'begin' and 'end'.
• you can also configure anything seprately for different type of files.
• now you can even decide to let some operators (like + - * / , ==) hilighted with the parentheses together.
• json style configuration used, more understandable and readable, easier for advanced configuration.
• the code is shorter and easier to be read now.
• smoother and faster.
• the chinese document is added.

Install:

via Vundle:

Plugin 'luochen1990/rainbow'
let g:rainbow_active = 1 "0 if you want to enable it later via :RainbowToggle

Manually:

• first, put rainbow.vim(this file) to dir ~/.vim/plugin or vimfiles/plugin

• second, add the follow sentences to your .vimrc or _vimrc :

   let g:rainbow_active = 1 "0 if you want to enable it later via :RainbowToggle

• third, restart your vim and enjoy coding.

Configure:

There is an example for advanced configuration(which i'm using), add it to your vimrc and edit it as you wish(just keep the format).

	let g:rainbow_conf = {
	\	'guifgs': ['royalblue3', 'darkorange3', 'seagreen3', 'firebrick'],
	\	'ctermfgs': ['lightblue', 'lightyellow', 'lightcyan', 'lightmagenta'],
	\	'operators': '_,_',
	\	'parentheses': ['start=/(/ end=/)/ fold', 'start=/\[/ end=/\]/ fold', 'start=/{/ end=/}/ fold'],
	\	'separately': {
	\		'*': {},
	\		'tex': {
	\			'parentheses': ['start=/(/ end=/)/', 'start=/\[/ end=/\]/'],
	\		},
	\		'lisp': {
	\			'guifgs': ['royalblue3', 'darkorange3', 'seagreen3', 'firebrick', 'darkorchid3'],
	\		},
	\		'vim': {
	\			'parentheses': ['start=/(/ end=/)/', 'start=/\[/ end=/\]/', 'start=/{/ end=/}/ fold', 'start=/(/ end=/)/ containedin=vimFuncBody', 'start=/\[/ end=/\]/ containedin=vimFuncBody', 'start=/{/ end=/}/ fold containedin=vimFuncBody'],
	\		},
	\		'html': {
	\			'parentheses': ['start=/\v\<((area|base|br|col|embed|hr|img|input|keygen|link|menuitem|meta|param|source|track|wbr)[ >])@!\z([-_:a-zA-Z0-9]+)(\s+[-_:a-zA-Z0-9]+(\=("[^"]*"|'."'".'[^'."'".']*'."'".'|[^ '."'".'"><=`]*))?)*\>/ end=#</\z1># fold'],
	\		},
	\		'css': 0,
	\	}
	\}

• 'guifgs': colors for gui interface, will be used in order.
• 'ctermfgs': colors for terms
• 'operators': describe the operators you want to highlight(read the vim help :syn-pattern)
• 'parentheses': describe what will be processed as parentheses, a pair of parentheses was described by two re pattern
• 'separately': configure for specific filetypes(decided by &ft), key * for filetypes without separate configuration, value 0 means disable rainbow only for this type of files
• keep a field empty to use the default setting.

User Command:

• :RainbowToggle --you can use it to toggle this plugin.
