Semantic-Highlight.vim

Where every variable is a different color, an idea popularized by Evan Brooks' blog post.

Install

Vundle or Neobundle:

Plugin 'jaxbot/semantic-highlight.vim'

Pathogen:

git clone https://github.com/jaxbot/semantic-highlight.vim.git

Usage

In a file, run :SemanticHighlight to convert variables into colors. Run :SemanticHighlightRevert to revert.

You can also map :SemanticHighlightToggle to a shortcut to toggle the effect on and off:

:nnoremap <Leader>s :SemanticHighlightToggle<cr>

Customization

Set g:semanticTermColors and/or g:semanticGUIColors to a list of colors, then run RebuildSemanticColors to flush the cache. The color lists look like:

let s:semanticGUIColors = [ '#72d572', '#c5e1a5', '#e6ee9c', '#fff59d', '#ffe082', '#ffcc80', '#ffab91', '#bcaaa4', '#b0bec5', '#ffa726', '#ff8a65', '#f9bdbb', '#f9bdbb', '#f8bbd0', '#e1bee7', '#d1c4e9', '#ffe0b2', '#c5cae9', '#d0d9ff', '#b3e5fc', '#b2ebf2', '#b2dfdb', '#a3e9a4', '#dcedc8' , '#f0f4c3', '#ffb74d' ]

let g:semanticTermColors = [28,1,2,3,4,5,6,7,25,9,10,34,12,13,14,15,16,125,124,19]

Either list can also be set in your vimrc

Language support

This plugin is language agnostic, meaning it will work on any language with words. However, some languages have been tweaked by default to disable highlighting of language keywords.

Current language support with keyword blacklists:

JavaScript
Ruby
PHP
Python
CoffeeScript

This can be customized locally by populating g:semanticBlacklistOverride like so:

let g:semanticBlacklistOverride = {
	\ 'javascript': [
	\	'setTimeout',
	\	'break',
	\	'dance',
	\ ]
\ }

If you want to add language support to the plugin itself, feel free to edit autoload/blacklist.vim and submit a pull request with your changes. Help is appreciated!

Kudos

Big thanks to John Leimon, whose Semantic C/C++ Vimscript was inspirational in the construction of this one.

Also big thanks to everyone who submitted bugs, suggestions, and pull requests!
