module Webgen::ContentProcessor::HtmlHead
General information¶ ↑
Inserts additional links to CSS/JS files and other HTML head meta info directly before the HTML head end tag.
The data used by this content processor is taken from the Context object. Therefore this processor should be the last in the processing pipeline so that all other processors have been able to set the data.
Use the methods defined on the special Webgen::Context::HtmlHead::Proxy object which can be accessed via Webgen::Context#html_head to provide values.
Internal details¶ ↑
The key :cp_html_head of context.persistent is used (the normal context.options won't do because the data needs to be shared 'backwards' during the rendering) and it has to be a Hash with the following values:
- :js_file
-
An array of already resolved relative or absolute paths to Javascript files.
- :js_inline
-
An array of Javascript fragments to be inserted directly into the head section.
- :css_file
-
An array of already resolved relative or absolute paths to CSS files.
- :css_inline
-
An array of CSS fragments to be inserted directly into the head section.
- :meta
-
A hash with key-value pairs from which 'meta' tags are generated. The keys and the values will be properly escaped before insertion. The entries in the meta information 'meta' of the content node are also used and take precedence over these entries.
Duplicate values will be removed from the above mentioned arrays before generating the output.
Public Class Methods
Insert the additional header information.
Return a string containing HTML link tags to the links from the 'link' meta information.
