Class: WikiChunk::BlikiLink

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

Overview

This chunk handles [bliki[entry name]]. This format has been extended for some other pre-configured redirection. Probably a bad name now, as we’re using this for any link outside the current web, but if I change the class name it’ll break existing storages.
