Asset Packager is in a book!

My plugin AssetPackager has been featured in Scott Raymond’s new book Ajax on Rails !

Thanks Scott! Everyone go buy a copy. AssetPackager has a full section in Chapter 9 – Performance. Nice.

Scott, you’re right of course – no need for me to modify the plugin. Just thought it would DRY it up by having it in the plugin. Although it expects a flattened array, forcing a flatten makes it a little more flexible.

Thanks for a great plugin. It really helps on SSL sites, where assets are not cached.

Brett – Instead of modifying the plugin itself, why not do:

@javascripts.flatten!

in your controller? Asset Packager expects a flattened array of sources already. :)

That’s

sources.flatten!

As I optimize my site further, I want to conditionally include certain javascripts/stylesheets on different pages. What I want is a

<%= javascript_include_merged @javascripts %>

once in my header partial. Then in any page, I can add the javascripts I need.

But I needed to add a line to the beginning of javascript_include_merged and stylesheet_link_merged in asset_packager_helper.rb:

@sources.flatten!@

It works for me.

Sigh, I trust you’ll be able to figure out what the source code ought to be.

Asset Packager doesn’t behave as expected when :default JavaScript includes are redefined. This can be corrected with a small change.

[‘prototype’, ‘effects’, ‘dragdrop’, ‘controls’] + ActionView::Helpers::AssetTagHelper.send(:class_variable_get, ’@@javascript_default_sources’) + (File.exists?(”#{RAILS_ROOT}/public/javascripts/application.js”) ? [‘application’] : []) + sources[(sources.index(:defaults) + 1)..sources.length] sources.delete(:defaults) end

sources.collect!{|s| s.to_s}
  sources = (RAILS_ENV == "production" ? 
    AssetPackage.targets_from_sources("javascripts", sources) : 
    AssetPackage.sources_from_targets("javascripts", sources))
end

sources.collect {|source| javascript_include_tag(source, options) }.join("\n")
