This month's presentation was on the Git::Repository Perl module, given by me. In both my jobs, I use the Git::Repository module to automate releases.
At Double Cluepon, I use it to create the
release packages based on tagged commits, so that releasing our software is
git tag vX.X.X && git push --tags. A Perl script builds every package
and then pushes them to our update server, where the game will check for a new
At Bank of America, we use it to combine our 20-30 Perl distributions into a single release. Using git submodules, we have a "release repository" that holds references to all the modules for each team's releases (some are team-specific, others are shared between teams). A Perl script manages the submodules, determines when the submodule refs need to be updated, tags and branches for each release, and finally builds and installs our modules using Module::Build and local::lib.
All this Git stuff gave me some ideas for possible useful code I can release, perhaps leading to me finally recovering my CPAN ID.
