App::Cmdline::Options::Basic - set of basic options for command-line applications
version 0.1.2
# In your module that represents a command-line application:
sub opt_spec {
my $self = shift;
return $self->check_for_duplicates (
[ 'check|c' => "only check the configuration" ],
...,
$self->composed_of (
'App::Cmdline::Options::Basic', # here are the basic options added
'App::Cmdline::Options::DB', # here may be other options
)
);
}
This is a kind of a role module, defining a particular set of command-line options and their validation. See more about how to write a module that represents a command-line application and that uses this set of options in App::Cmdline.
Particularly, this module specifies the basic options, usually used by any command-line application:
[ 'h' => "display a short usage message" ],
[ 'version|v' => "display a version" ],
It prints a short usage message, something like this:
Usage: myapp [non-bundled short or long options]
-h display a short usage message
-v --version display a version
It print the version of the application and exits in one of the two possible ways: If it is called from and eval expression, it dies (so you can catch it and continue). Otherwise, it exists with the exit code zero.
