CompassElephantBundle

A Bundle to use the CompassElephant library in a Symfony2 project

This bundle scans your compass projects on every request, and checks if they needs to be recompiled. It takes care of dependencies, so you can use compass with @import, sprite generation etc. without problems. Let Symfony watch your project and forget about it.

Notice

version >= 0.1 of this bundle do not uses the native checker anymore, as it's not supported by compass from 1.x version.

The staleness_checker option is still available for compatibility, but it's ignored.

Installation

composer

Installing with composer is as simple as typing in the root of your symfony project

$ composer require cypresslab/compass-elephant-bundle:~1.0

Register the bundle

Register the bundle in the AppKernel.php file inside the dev section

app/AppKernel.php

<?php
if (in_array($this->getEnvironment(), array('dev', 'test'))) {
    // ...other bundles ...
    $bundles[] = new Cypress\CompassElephantBundle\CypressCompassElephantBundle();
}

Configuration

Add the configuration in your config file (for the dev environment)

app/config_dev.yml

cypress_compass_elephant:
    compass_projects:
        my-nice-project:
            path: %kernel.root_dir%/../src/Cypress/DemoBundle/Resources/public/compass

my-compass-project is a random name for this example. Pick the name you want

path has to be an existing directory. By default, if the directory is empty, CompassElephant try to init a compass project

be gentle with your server cpu: remove the listener on production as it's not needed. You will serve static css files

app/config_prod.yml

cypress_compass_elephant:
    register_listener: false

Important

Remember that the apache user needs write access to the "sass" folder, the "stylesheet" folder and the config.rb file. If you use compass defaults you will have everything inside the same project folder. You can give permission to all files inside. But you can as well change the position of the stylesheets folder to be outside the project. CompassElephant parses the config file and uses it, just remember to set the right permissions on the folders you define inside compass config file.

Add the stylesheets to your templates

assetic

{% stylesheets filter="yui_css"
    "@CypressDemoBundle/Resources/public/compass/stylesheets/screen.css" %}
    <link href="{{ asset_url }}" type="text/css" rel="stylesheet" />
{% endstylesheets %}

without assetic

<link href="{{ asset('bundles/cypressdemo/compass/stylesheets/screen.css') }}" type="text/css" rel="stylesheet" />

Enjoy!

Complete configuration reference

cypress_compass_elephant:
    register_listener: true
    compass_binary_path: "/usr/local/bin/compass"
    compass_projects:
        blog:
            path: %kernel.root_dir%/../src/Cypress/BlogBundle/Resources/public/compass
            config_file: config.rb
            auto_init: true
            target: sass/screen.scss

• register_listener whether to register the listener that compiles the project, if needed, on every request. Turn this off in production as you don't want to watch your scss files on every request...even if it take only 5-10 ms (be sure to upload the compiled css files during deploy)
• compass_binary_path is useful to force a binary that is not the default one that "which compass" gets.
• compass_projects is a collection of all the compass projects in your symfony project (maybe one for application)
• config_file is the name of te config file for compass. Defaults to config.rb, the standard one. You can use this setting to compile different stylesheets based on environment
• auto_init if set to false disable the init feature on an empty folder. Defaults to true
• target Tells CompassElephant to compile that single file, and not the whole compass project. The target should be the relative path from the root of your compass project

Command line

There is a simple command to compile all compass projects. It's really useful for deploy procedures (capifony)

for example, in a capifony deploy you could trigger this command

$ ./app/console cypress:compass:compile -e=prod

How it works

This bundle register an event listener that, on every request, check if the projects defined in the config_dev.yml files are in "clean" state or needs recompile.

If the project does not need to be recompiled, it adds a really small overhead to symfony.
