SVN::Notify 2.30 Adds Issue Tracking Links

I released a new version of SVN::Notify last night, 2.30. This new version has a few things going for it.

First, and most obviously from the point of view of users of the HTML subclass, I’ve added new options for specifying Request Tracker, Bugzilla, and JIRA URLs. The --rt-url, --bugzilla-url, and --jira-url options have an effect much like the parallel feature in CVSspam: pass in a string with the spot for the ID represented by %s, such as http://rt.cpan.org/NoAuth/Bugs.html?id=%s for RT or http://bugzilla.mozilla.org/show_bug.cgi?id=%s for Bugzilla. SVN::Notify::HTML will then look for the appropriate strings (such as “Ticket # 1234” for RT or “Bug # 4321” for Bugzilla) and turn them into URLs.

This functionality has been extended to the old --viewcvs-url option, to. For the sake of consistency, it now also requires a URL of the same form (although if SVN::Notify doesn’t see %s in the string, it will append a default and emit a warning), and will be used to create links for strings like “Revision 654” in the log message.

SVN::Notify::HTML has an additional new option, --linkize, that will force any email addresses or URLs it finds in the log message to be turned into links. Again, this works like it does for CVSspam; I’m grateful to Jeffrey Friedl’s Mastering Regular Expressions, Second Edition for the excellent regular expressions for matching URLs and email addresses.

All of this was made possible by moving the processing of options from svnnotify to SVN::Notify->get_options and adding a new class method, SVN::Notify->register_attributes. This second method allows Bricolage subclasses to easily add new attributes; register_attributes() will create accessor methods and add command-line option processing for each new attribute required by a subclass. Then, when you execute svnnotify --handler HTML, SVN::Notify->get_options processes the default options, loads the SVN::Notify::Handler subclass, and then processes any options specified by the subclass. The short story is that all of this is the detail-oriented way of saying that it is easier to subclass SVN::Notify and be able to automatically load the necessary options and attributes via the same executable, svnnotify.

This change was motivated not only by my desire to add the new features to SVN::Notify::HTML, but also by Autrijus’ new modules, SVN::Notify::Snapshot and SVN::Notify::Config. Thanks Autrijus!

I’ll try to get a nice example of all this functionality up in the next few days; if anyone else creates one first, send it to me! But in the meantime, enjoy!

SVN::Notify 2.20 Adds Colorized Diffs

After getting prodded by Erik Hatcher, I went ahead and added another subclass to SVN::Notify. This one adds a pretty colorized diff to the message, instead of just the plain text one. See an example here. I’ve also added links from the lists of affected files into the diffs in the HTML and new HTML::ColorDiff layouts.


Update: And now I’ve released SVN::Notify 2.21 with a few minor fixes, including XHTML 1.1 compliance.
