I recently blogged about Ask, my new(ish) module for interacting with users via STDIN/STDOUT, a GUI, or whatever means possible. Writing GUI code in Perl unfortunately requires you to compile non-core modules such as Gtk2, Wx or Tk. There is…
In many scripts, we need to prompt the end user for information – this could be a prompt for a file name, a selection from a list of options, or an answer to a yes/no question. The traditional approach to…
According to metacpan.org, MooX-ClassAttribute-0.001 was the first upload of 2013! Yay!…
