This release incorporates the feedback I have got from fellow perl mongers.

The most notable change is that not all attributes will be exposed to the CLI, but only those defined with the new 'option' keyword.

The 'option' keyword is basically just syntactic sugar for adding an attribute with a special trait which marks attributes as command-line options. The main advantage for this approach is that you don't have to explicitly prevent internal attributes - possibly originating from consumed roles deep down in your code - from being exposed to the command line.

Furthermore I have cleaned up the meta classes, making it easier to write custom plugins which can modify almost every part of MooseX-App's behaviour, and fixed a couple of bugs I have discovered while switching App::iTan from MooseX::App::Cmd to MooseX::App.

App::iTan is a little command-line application - written a couple of years ago - which helps me to manage indexed transaction authentication numbers (iTAN) for my online-banking account. Hope you like it.

App-iTan, Business-UPS-Tracking, Game-Lacuna-Task, Mac-iPhoto-Exif and many more not publicly available). However most of the CPAN tools I generally use to build these applications either are not as user-friendly as I would like them to be, or are not flexible enough.

I decided to change that and wrote MooseX-App.

It handles commands with multiple subcommands, generates usage text, error messages on wrong user-input, validates options, and lets you write your program as easy-to-test and reusable classes. Just as App-Cmd (or MooseX-App-Cmd respectively). However compared to these options it ...

  • is more flexible
  • supports plugins that can overdrive almost all of its behaviour
  • does not impose a certain application structure on you (thus making code reusage and testing easier)
  • does not pollute your command classes with many methods since most of its logic is implemented via meta classes
  • and is quite user friendly by providing useful input hints, better error messages as well as optional colorful output and bash completion

So let me give you a short example:



Hope you like it.
