Converting ACE from Subversion to Git

The ace-svn-to-git.sh script will use git-svn to convert ACE's Subversion repository to Git with the --stdlayout flag so the trunk, tags, and branches are handled mostly as expected (more below). The --prefix=svn/ option puts all of those tags and branches under the svn reference namespace, and the --authors-file option maps the Subversion author names to the current GitHub profiles of the three authors in ACE's history.

Parsing JSON with Regular Expressions

When I learned of regular expression engines that support recursion I thought I could write a recursive-descent parser in regex. Since I've written JSON parsers a few times and it's a simple spec, I chose that as the test case. In the end I created two versions.

Demonstration of an ArcDiagram layout function with both distance-based and compact level modes. The compact mode works better for orthogonal edges, and can use much less vertical space. The distance mode works better for curved arc edges.
