LESS on Rails.
More is a plugin for Ruby on Rails applications. It automatically parses your applications .less files through LESS and outputs CSS files.
In details, More does the following:
- Recursively looks for LESS (
.less) files inapp/stylesheets - Ignores partials (prefixed with underscore:
_partial.less) - these can be included with@importin your LESS files - Saves the resulting CSS files to
public/stylesheetsusing the same directory structure asapp/stylesheets
LESS extends CSS with: variables, mixins, operations and nested rules. For more information, see http://lesscss.org.
The old less-for-rails plugin looked for .less files in public/stylesheets. This plugin looks in app/stylesheets.
To migrate, you can either set Less::More.source_path = Rails.root + "/public/stylesheets", or move your .less files to app/stylesheets.
More depends on the LESS gem. Please install LESS first:
$ gem install less
Use this to install as a plugin in a Ruby on Rails app:
$ script/plugin install git://github.com/cloudhead/more.git
Use this if you prefer to use git submodules for plugins:
$ git submodule add git://github.com/cloudhead/more.git vendor/plugins/more
$ script/runner vendor/plugins/more/install.rb
Upon installation, a new directory will be created in app/stylesheets. Any LESS file placed in this directory, including subdirectories, will
automatically be parsed through LESS and saved as a corresponding CSS file in public/stylesheets. Example:
app/stylesheets/clients/screen.less => public/stylesheets/clients/screen.css
If you prefix a file with an underscore, it is considered to be a partial, and will not be parsed unless included in another file. Example:
<file: app/stylesheets/clients/partials/_form.less>
@text_dark: #222;
<file: app/stylesheets/clients/screen.less>
@import "partials/_form";
input { color: @text_dark; }
The example above will result in a single CSS file in public/stylesheets/clients/screen.css.
Any .css file placed in app/stylesheets will be copied into public/stylesheets without being parsed through LESS.
Source path: the location of your LESS files (default: app/stylesheets)
Less::More.source_path = "public/stylesheets/less"
Destination Path: where the css goes (public/destination_path) (default: stylesheets)
Less::More.destination_path = "css"
More can compress your files by removing extra line breaks (default: true)
Less::More.compression = false
More inserts headers in the generated CSS files, letting people know that the file is in fact generated and shouldn't be edited directly. (default: true)
Less::More.header = false
To configure More for a specific environment, add configuration options into the environment file, such as config/environments/development.rb.
If you wish to apply the configuration to all environments, place them in config/environment.rb.
More provides a set of Rake tasks to help manage your CSS files.
To parse all LESS files and save the resulting CSS files to the destination path, run:
$ rake more:generate
To delete all generated CSS files, run:
$ rake more:clean
This task will not delete any CSS files from the destination path, that does not have a corresponding LESS file in the source path.
Check in all the generated css(destination path), they are only generated in development
