A Redmine plugin that replaces the default syntax highlighting engine (CodeRay) with a JavaScript based syntax highlighter.
Next, use Rails’ handy-dandy plugin installer to grab this plugin:
script/plugin install git://github.com/k2s/redmine_js_syntax_highlighter.git
Alternatively, you can just copy content of edmine_js_syntax_highlighter
directory into vendor/plugins
.
