Class: WikiChunk::Link

Inherits:
WikiLink show all
Defined in:
app/models/chunks/wiki.rb

Overview

This chunk handles [[bracketted wiki words]] and [[AliasedWords|aliased wiki words]]. The first part of an aliased wiki word must be a WikiWord. If the WikiWord is aliased, the link_text field will contain the alias, otherwise link_text will contain the entire contents within the double brackets.

NOTE: This chunk must be tested before WikiWord since

a WikiWords can be a substring of a WikiLink.
