The Moose role is designed to manage command line options in software, providing an efficient way to handle user input and modify program behavior.
MooseX::Getopt is a software role that substitutes the regular constructor for creating objects with parameters passed from the command line. With the help of introspection of your class's attributes, this module attempts to understand the command line params as much as possible. Suppose there is a type constraint defined; in that case, the name of your attribute will be used as the command line option, and Getopt::Long will be configured to handle the option accordingly.
For non-default command line option names and aliases, you can use MooseX::Getopt::Meta::Attribute::Trait or the attribute metaclass MooseX::Getopt::Meta::Attribute. In contrast, MooseX::Getopt::Meta::Attribute::NoGetopt or the attribute metaclass MooseX::Getopt::Meta::Attribute::NoGetopt can be used to have MooseX::Getopt ignore your attribute in the command line options.
By default, if the attribute starts with an underscore, it will not be given support for command line arguments, unless the attribute's metaclass is set to MooseX::Getopt::Meta::Attribute. If you want to avoid leading underscores in the accessors' names, you can follow the codes mentioned in the example provided.
If your class uses a configfile-loading role based on MooseX::ConfigFromFile, Dthe new_with_options method of MooseX::Getopt must load the configfile specified by the --configfile option (or the default you've given for the configfile attribute), making the work simpler.
Multiple options specified in several places follow the following priority order: command line overrides configfile, which overrides explicit new_with_options parameters.
To use the module, you can define your class and then use 'MooseX::Getopt' software. For example, the code snippet describes how to use MooseX::Getopt in your script or on the command line.
