Setting default package versions with MacPorts

Given a working Perl 5.12 install (via MacPorts), doing a sudo port install perl5.16 does not update the perl symlink:

% ls -alF /opt/local/bin/perl
lrwxr-xr-x 1 root admin 8 Jun 6 15:19 /opt/local/bin/perl@ -> perl5.12

The magic incantation is to install a the perl5_16 variant of the perl5 package:

sudo port install perl5 +perl5_16

With this done, the symlink is updated and perl loads the expected version.

% ls -alF /opt/local/bin/perl                                                                                                    
lrwxr-xr-x  1 root  admin  8 Aug  9 12:45 /opt/local/bin/perl@ -> perl5.16
% perl -v

JSPWiki-translate-perl and HTML::WikiConverter-MoinMoin

moinmoin-client-crypt was the fun part of a recent Wiki migration project I did. The tedious prelude was getting the content out of an aging JSPWiki version and into MoinMoin.

After some aborted attempts at translating the JSPWiki source from scratch, I decided the path of least resistance would be to leverage HTML::WikiConverter to translate the HTML output of JSPWiki. This turned out to be time consuming as well. To anyone else going down this path I offer up:

  1. A patched version of HTML::WikiConverter-MoinMoin that includes fixes for intra-wiki links, inline images, horizontal rules, and definition lists.
  2. A collection of scripts, dubbed JSPWiki-translate-perl, for retrieving HTML from JSPWiki, pre-processing it to make it more palatable for HTML::WikiConverter, and for generating a MoinMoin-style directory layout to contain it.

The original author of HTML::WikiConverter-MoinMoin seems to have abandoned it. I can sympathize; I certainly hope to avoid translating another Wiki any time soon!
