What's new on CPAN - October 2015

Nov 3, 2015 by David Farrell

Welcome to “What’s new on CPAN”, a curated look at last month’s new CPAN uploads for your reading and programming pleasure. Enjoy!

Module of the month

App::Skeletor bootstraps new Perl projects based on customizable templates. Similar to Dist::Zilla (why do all these builder tools have such great names?) but intentionally less ambitious, App::Skeletor looks more useful as a component of a Perl app or a starter kit for module developers. You can run it from the terminal:

$ skeletor --template Skeletor::Template::Example \
  --as My::App \
  --directory ~/Projects \ 
  --author 'John Doe' \
  --year 2015

It’s early days but module author John Napiorkowski has already written enough documentation to get you started. It would be great if we could develop a set of community templates for Perl modules. Take a look today!
