gem install codemirror-rails
CodeMirror for Rails >= 3.1
All of the assets from the most latest stable CodeMirror release are vendored so that you can use them with the asset pipeline. At a minimum, you will probably want the following in your application.js:
//= require codemirror
And in your application.css:
/* *= require codemirror */
Adding a mode
Additional syntax modes can be added to your application.js:
//= require codemirror/modes/ruby
Adding an addon
Additional addons can be added in your application.js:
//= require_tree codemirror/addons/dialog
And your application.css:
/* *= require_tree codemirror/addons/dialog */
Adding a keymap
Additional keymap bindings can be added to your application.js:
//= require codemirror/keymaps/vim
Adding a theme
Additional CSS themes can be added to your application.css
/* *= require codemirror/themes/night */
If your project is using precompiling, depending on your method of grabbing files to precompile, you might need to add the below line to your ```` application.rb```, to get rails to precompile all js, css files used by codemirror. You can also manually whitelist only the files that you use.
config.assets.precompile += ["codemirror*", "codemirror/**/*"]
CodeMirror for Rails 3
You can use the generator included with this gem to copy the CodeMirror 2 assets into your Rails 3 public directory.
