Module: Jammit::Helper
- Defined in:
- lib/jammit/helper.rb
Overview
The Jammit::Helper module, which is made available to every view, provides helpers for writing out HTML tags for asset packages. In development you get the ordered list of source files – in any other environment, a link to the cached packages.

Instance Method Summary collapse
-
#include_javascripts(*packages) ⇒ Object
Writes out the URL to the bundled and compressed javascript package, except in development, where it references the individual scripts.
-
#include_stylesheets(*packages) ⇒ Object
If embed_assets is turned on, writes out links to the Data-URI and MHTML versions of the stylesheet package, otherwise the package is regular compressed CSS, and in development the stylesheet URLs are passed verbatim.
-
#include_templates(*packages) ⇒ Object
Writes out the URL to the concatenated and compiled JST file – we always have to pre-process it, even in development.
