NAME

Config::Resolver::Utils - Shared utilities for Config::Resolver and plugins

SYNOPSIS

# In your Config::Resolver::Plugin::MyPlugin.pm
package Config::Resolver::Plugin::MyPlugin;

use Config::Resolver::Utils qw(to_boolean is_hash);

if ( is_hash($foo) ) { ... }

my $bool = to_boolean('yes'); # returns 1

DESCRIPTION

This module provides a shared, public set of utility functions for use by Config::Resolver and any module in the Config::Resolver::Plugin::* namespace.

This ensures that all plugins can share a consistent, robust method for type-checking and boolean coercion.

EXPORTABLE SUBROUTINES

None of these are exported by default. You must request them.
