NAME

App::Spec::Run - App::Spec framework to run your app

DESCRIPTION

App::Spec::Run is the framework which runs your app defined by the spec. Your app class should inherit from App::Spec::Run::Cmd.

SYNOPSIS

    sub your_command {
        my ($self, $run) = @_;
        my $options = $run->options;
        $run->out("It works");
    }

METHODS

Constructor

You can create the object yourself like this:

    my $run = App::Spec::Run->new(
        spec => $appspec,
        cmd => App::YourApp->new,
    );

Or you use the runner method of App::Spec, which will create it for you:

    my $run = $appspec->runner(...);

Both methods take optional arguments:

    my $run = App::Spec::Run->new(
        spec => $appspec,
        cmd => App::YourApp->new,

        # Custom array instead of the default ARGV.
        # The contents of this array will be modified
        argv => \@my_arguments,
    );

run

    $run->run;

Actually runs your app. Calls process and finish.

process

    $run->process;

Processes input, validates, runs your command and fills the response object.

Does not print the output and does not exit.

out

    $run->out("Hello world!");

Appends to response output. Adds a newline if not present. You can also pass a data structure:

    $run->out($hashref);

This will be formatted with Data::Dumper.

See also App::Spec::Plugin::Format.

err

    $run->err("Oops, that went wrong");

Appends to response error output. Adds a newline if not present

halt

    $run->halt;

Further processing is halted.

finish

    $run->finish;

Prints the output and exits with the exit code stored in response.

process_input

    $run->process_input(
        option_specs => \%option_specs,
        param_specs => \%param_specs,
    );

process_parameters

    $run->process_parameters(
        parameter_list => $global_parameters,
        param_specs => $param_specs,
    );

run_op

    $run->run_op("yourcommand");
    # shortcut for
    $run->cmd->yourcommand($run);

completion_output

    $run->completion_output(
        param_specs => \%param_specs,
        completion_parameter => $completion_parameter,
    );

Is called when in completion mode

colored

Returns the given text colored, if colors are active for the given output.

    $msg = $run->colored('err', [qw/ error /], "Oops");
    $msg = $run->colored('out', [qw/ green /], "Everything is fine!");

colorize

    my $color_active = $run->colorize('out');
    my $color_error_active = $run->colorize('err');

Returns 1 or 0 if given output color are active. That means, the output is going to a terminal instead of being redirected.

colorize_code

    my $colored = $run->colorize_code('out');
    my $text = $colored->(['green'], "Hurray");
    # or
    my $text = "Hurray";
    $colored->(['green'], $text);

Returns a coderef which you can use for coloring

colorize_error

    my $msg = $run->colorize_error("ouch");

Returns the message in the standard error color (bold red).

error_output

    $run->error_output;

Outputs any errors.

Calls halt

event_globaloptions

Calls any plugin that needs to know

subscribe

A plugin can subscribe for an event:

    $run->subscribe(
        print_output => {
            plugin => $self,
            method => "print_output",
        },
