NAME
    Mojolicious::Plugin::AssetPack - Compress and convert css, less, sass
    and javascript files

VERSION
    0.02

SYNOPSIS
    In your application:

      use Mojolicious::Lite;

      plugin AssetPack => { rebuild => 1 };

      # add a preprocessor
      app->asset->preprocessors->add(js => sub {
        my($assetpack, $text, $file) = @_;
        $$text = "// yikes!\n" if 5 < rand 10;
      });

      # define assets: $moniker => @real_assets
      app->asset('app.js' => '/js/foo.js', '/js/bar.js');
      app->asset('app.css' => '/css/foo.less', '/css/bar.scss', '/css/main.css');

      app->start;

    In your template:

      %= asset 'app.js'
      %= asset 'app.css'

    See also "register".

DESCRIPTION
  Production mode
    This plugin will compress scss, less, css and javascript with the help
    of external applications on startup. The result will be one file with
    all the sources combined. This file is stored in "Packed directory".

    This is done using "process".

    The actual file requested will also contain the timestamp when this
    server was started. This is to help refreshing cache on change. Example:

      <script src="/packed/app.1379243728.js">

  Development mode
    This plugin will expand the input files to multiple script or link tags
    which makes debugging and development easier.

    This is done using "expand".

    TIP! Make morbo watch your less/sass files as well:

      $ morbo -w lib -w templates -w public/sass

  Packed directory
    The output directory where all the compressed files are stored will be
    "public/packed", relative to the application home:

      $app->home->rel_dir('public/packed');

  Preprocessors
    This library tries to find default preprocessors for less, scss, js and
    css.

    NOTE! The preprocessors require optional dependencies to function
    properly. Check out "detect" in
    Mojolicious::Plugin::AssetPack::Preprocessors for more details.

ATTRIBUTES
  minify
    Set this to true if the assets should be minified.

  preprocessors
    Holds a Mojolicious::Plugin::AssetPack::Preprocessors object.

  rebuild
    Set this to true if the assets should created, even though they exist.

METHODS
  add
      $self->add($moniker => @rel_files);

    Used to define new assets aliases. This method is called when the
    "asset()" helper is called on the app.

  expand
      $bytestream = $self->expand($c, $moniker);

    This method will return one tag for each asset defined by the
    "$moniker".

    Will also run "less" or "sass" on the files to convert them to css,
    which the browser understand.

    The returning bytestream will contain style or script tags.

  process
      $self->process($moniker);

    This method use "process" in
    Mojolicious::Plugin::AssetPack::Preprocessors to convert and/or minify
    the sources pointed at by $moniker.

    The result file will be stored in "Packed directory".

  register
      plugin 'AssetPack', {
        minify => $bool, # compress assets
        no_autodetect => $bool, # disable preprocessor autodetection
        rebuild => $bool, # overwrite if assets exists
      };

    Will register the "compress" helper. All arguments are optional.

    "minify" will default to true if "mode" in Mojolicious is "production".

    "rebuild" can be set to true to always rebuild the compressed files when
    the application is started. The default is to use the cached files.
