172 MakeClicky detects various formats of data in headers and email
173 messages, and extends them with supporting links. By default, RT
174 provides two formats:
176 * 'httpurl': detects http:// and https:// URLs and adds '[Open URL]'
179 * 'httpurl_overwrite': also detects URLs as 'httpurl' format, but
180 replace URL with link.
182 To extend this with your own types of data, use the callback.
183 It will be provided with:
185 * 'types': An array reference of hash references. Modify this array
186 reference to add your own types; the first matching type will be
187 used. Each hashref should contain:
188 - 'name': The name of the data format; this is used in the
189 configuration file to enable the format.
190 - 'regex': A regular expression to match against
191 - 'action': The name of the action to run (see "actions", below)
193 * 'actions': A hash reference of 'actions'. Modify this hash
194 reference to change or add action types. Values are subroutine
195 references which will get called when needed. They should return
196 the modified string. Note that subroutine must escape HTML.
198 * 'handler': A reference to a subroutine reference; modify it if you
199 have to. This can be used to add pre- or post-processing around
