Work in progress
This module is still work in progress and a hack-ish replacement for the SilverStripe Requirements Backend. This module exists because of current limitations in SilerStripe Requirements and might change its API or be completely obsolete once Requirements are re-factored.
Current Features
- compile sass/scss files using sassc (libsass)
- compile less files using less.php
Installation
Requirements for using sassc
- *nix based system. Windows Servers currently not supported
- php needs to be able to shell execute commands
- php needs write permissions to the css files and the combined_files folder
- sassc needs to be installed on your system
If your sassc executable is not in any of the paths, you can set the constant
SS_SASSC_PATH (
define('SS_SASSC_PATH', '/path/to/sassc')
).
Requirements for using less
- the composer package
leafo/lessphp
Installing the module
- Install the module using composer or download and place in your project folder
- Run
?flush=1
Installing sassc
If your system does not have sassc installed, you will need to install this as well. At time of writing this, I know of no existing package or pre-compiled binary, so you either have to compile it yourself or use Zauberfisch's semi-regularly build (debian) (this link might change in the future).
(Note: on shared web hosting it might not be possible to use sassc, but on some it will work to upload the binary to your project folder and set define('SS_SASSC_PATH', BASE_PATH . '/sassc')
)
Usage
By itself, this module does nothing. You will have to set the backend for Requirements.
A good place to do this is in PageController->init()
but can be at any other place as well.
Just make sure you set the backend before you use any other Requirements methods.
class PageController extends \SilverStripe\CMS\Controllers\ContentController {
// ...
public function init() {
Requirements::set_backend(new \BetterRequirements\Backend());
parent::init();
// ...
}
// ...
}
After this, you can use Requirements just the same as you did before, with one addition:
You can require sass/scss/less files.
The backend will replace 'sass'/'scss'/'less' in the file path and append '.css'.
// create and require mysite/css/myfile.scss.css
\SilverStripe\View\Requirements::css(project() . '/scss/myfile.scss');
// will create and require mysite/css/otherfile.sass.css
\SilverStripe\View\Requirements::css('mysite/sass/otherfile.sass');
// will create and require themes/mytheme/css/myfile.less.css
\SilverStripe\View\Requirements::css($this->ThemeDir() . '/less/myfile.less');
// it also works with combined files and mixed file types:
\SilverStripe\View\Requirements::combine_files('main.css', [
project() . '/css/normal-file.css',
project() . '/scss/scss-file.scss',
project() . '/less/less-file.less',
project() . '/scss/main.scss',
project() . '/less/main.less',
]);
Compiling/Preprocessing
Compiling/Preprocessing will take place when one of the following conditions is met:
?flush=1
(will re-compile all files)- config
\BetterRequirements\Backend.compile_in_live
- Site is in dev mode and config
\BetterRequirements\Backend.compile_in_dev
is true
You can change the configuration for this in a yml config file:
\BetterRequirements\Backend:
compile_in_live: true # default: false
compile_in_dev: true # default: true
Should you experience a long dalay until files get compiled after you change them, try to change the cache key to md5_file, then the file check will actually consider the content rather thant he file timestamp:
\BetterRequirements\Backend:
cache_key_method: 'md5_file' # default: 'filemtime'
Notes
When compiling your sass/scss files both locally (dev) as well as on your server (eg automated after deployment), it is recommended to add your css files to .gitignore and exclude them from version control.
Composer is currently not compatible with sassc, however there is a workaround: Composer is a mix of ruby and sass, you can use the sass part with sassc and will only loose a small list of features (image-height, image-width, sprite functions, ...). Get the compass mixins from Igosuki/compass-mixins and see Zauberfisch's SilverStripe Boilerplate for example usage.
