Name

Class::Usul::TraitFor::RunningMethods - Try and run a method catch and handle any exceptions

Synopsis

use Moo;

extends 'Class::Usul';
with    'Class::Usul::TraitFor::RunningMethods';

Description

Implements the "run" method which calls the target method in a try / catch block. Handles any resulting exceptions

Configuration and Environment

Defines the following command line options;

c method

The method in the subclass to dispatch to

o options key=value

The method that is dispatched to can access the key/value pairs from the $self->options hash ref

umask

An octal number which is used to set the umask by the "run" method

v verbose

Repeatable boolean that increases the verbosity of the output

Defines the following attributes;

params

A hash reference keyed by method name. The values are array references which are flattened and passed to the method call by "run"

Subroutines/Methods

run

$exit_code = $self->run;

Call the method specified by the -c option on the command line. Returns the exit code

run_chain

$exit_code = $self->run_chain( $method );

Called by "run" when "select_method" cannot determine which method to call. Outputs usage if method is undefined. Logs an error if method is defined but not (by definition a callable method). Returns exit code FAILED

$method = $self->select_method;

Called by "run" it examines the "method" attribute and if necessary the extra command line arguments to determine the method to call
