Where every variable is a different color, an idea popularized by Evan Brooks' blog post.
Vundle or Neobundle:
git clone https://github.com/jaxbot/semantic-highlight.vim.git
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>
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
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:
This can be customized locally by populating
g:semanticBlacklistOverride like so:
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!
Adding characters to be included in highlights
Consider the following:
var $someObject = '1231'; var someObject = 1231;
autocommand outlined below, only the
someObject portion of the variable would be semantically highlighted, and highlighted the same colour as the
$-free variable. To have the preceding
$ included in the semantic highlight, use the following snippet in your vimrc:
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!
