Compiler optimization

[Pyvonix]

It's impossible to use Django-pipeline to build Bootstrap directly by configuration...

Exemple:

PIPELINE = {
    'COMPILERS': (
        'pipeline.compilers.sass.SASSCompiler',
    ),
    'SASS_BINARY': '/usr/bin/sass',
    'STYLESHEETS': {
        'bootstrap': {
            'source_filenames': (
               'my_bootstrap/_variables.scss',
               'bootstrap/bootstrap.scss',
               'my_bootstrap/_bootstrap.scss',
             ),
            'output_filename': 'css/bootstrap.min.css',
            'extra_context': {
                'media': 'screen,projection',
            }
        }
    }
}

The only way is to do it, is to create a file like:

@import "my_bootstrap/_variables";
@import "bootstrap/bootstrap";
@import "my_bootstrap/_bootstrap";

And call this file in source_filenames to compile it:

'source_filenames': (
   'build_bootstrap.scss',
)

This problem refers to the approach of the compiler who iter on each file specified in source_filenames to execute the command :

• actual behavior generate one .css for each .scss
• sould be one .css for every .scss give by source_filenames.

This could be an important optimization because we compile one file by section. Not anymore one file for one file and concatenate them to produce the final file.
