NAME

App::Easer - Simplify writing (hierarchical) CLI applications

VERSION

This document describes App::Easer version 2.012.

SYNOPSIS

#!/usr/bin/env perl
use v5.24;
use experimental 'signatures';
use App::Easer V2 => 'run';
my $app = {
   aliases     => ['foo'],
   help        => 'this is the main app',
   description => 'Yes, this really is the main app',
   options     => [
      {
         name        => 'foo',
         help        => 'option foo!',
         getopt      => 'foo|f=s',
         environment => 'FOO',
         default     => 'bar',
      },
   ],
   execute => sub ($instance) {
      my $foo = $instance->config('foo');
      say "Hello, $foo!";
      return 0;
   },
   default_child => '-self',    # run execute by default
   children => [
      {
         aliases => ['bar'],
         help => 'this is a sub-command',
         description => 'Yes, this is a sub-command',
         execute => sub { 'Peace!' },
      },
   ],
};
exit run($app, $0, @ARGV);

DESCRIPTION

NOTE: this software should be considered "late alpha" maturity. I'm mostly happy with the interface, but there are still a few things that might get changed. Anyway, if you find a release of App::Easer to work fine for you, it's fair to assume that you will not need to get a newer one later.

App::Easer provides the scaffolding for implementing hierarchical command-line applications in a very fast way.

Development today happens only in App::Easer::V2. The legacy interface is still available in App::Easer::V1, which is also the default but has its own documentation.
