app::cmd::simple
App::Cmd::Simple(3pm) User Contributed Perl Documentation App::Cmd::Simple(3pm)
NAME
App::Cmd::Simple - a helper for building one-command App::Cmd applications
VERSION
version 0.318
SYNOPSIS
in simplecmd:
use YourApp::Cmd;
Your::Cmd->run;
in YourApp/Cmd.pm:
package YourApp::Cmd;
use base qw(App::Cmd::Simple);
sub opt_spec {
return (
[ "blortex|X", "use the blortex algorithm" ],
[ "recheck|r", "recheck all results" ],
);
}
sub validate_args {
my ($self, $opt, $args) = @_;
# no args allowed but options!
$self->usage_error("No args allowed") if @$args;
}
sub execute {
my ($self, $opt, $args) = @_;
my $result = $opt->{blortex} ? blortex() : blort();
recheck($result) if $opt->{recheck};
print $result;
}
and, finally, at the command line:
knight!rjbs$ simplecmd --recheck
All blorts successful.
SUBCLASSING
When writing a subclass of App::Cmd:Simple, there are only a few methods that you might want to implement. They behave just like the same-
named methods in App::Cmd.
opt_spec
This method should be overridden to provide option specifications. (This is list of arguments passed to "describe_options" from
Getopt::Long::Descriptive, after the first.)
If not overridden, it returns an empty list.
validate_args
$cmd->validate_args(\%opt, @args);
This method is passed a hashref of command line options (as processed by Getopt::Long::Descriptive) and an arrayref of leftover arguments.
It may throw an exception (preferably by calling "usage_error") if they are invalid, or it may do nothing to allow processing to continue.
execute
Your::App::Cmd::Simple->execute(\%opt, @args);
This method does whatever it is the command should do! It is passed a hash reference of the parsed command-line options and an array
reference of left over arguments.
WARNINGS
This should be considered experimental! Although it is probably not going to change much, don't build your business model around it yet,
okay?
App::Cmd::Simple is not rich in black magic, but it does do some somewhat gnarly things to make an App::Cmd::Simple look as much like an
App::Cmd::Command as possible. This means that you can't deviate too much from the sort of thing shown in the synopsis as you might like.
If you're doing something other than writing a fairly simple command, and you want to screw around with the App::Cmd-iness of your program,
Simple might not be the best choice.
One specific warning... if you are writing a program with the App::Cmd::Simple class embedded in it, you must call import on the class.
That's how things work. You can just do this:
YourApp::Cmd->import->run;
