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.
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.
