Overview

The Message class represents a mechanism for dynamically handling and formatting messages.

It supports the substitution of placeholders within a message template with actual data.

The class leverages file-based message templates, allowing for easy localization or customization of messages.

It integrates seamlessly with the Resources module to access these templates from a customizable path set via the "SCRIPT_CUSTOM_RESOURCES" environment variable or from a default library path.

Examples:

Creating a new Message instance and formatting it

# Assuming "hellow_world" is a file that says "Hello, world!"
message = Message.new("hellow_world")
puts message.to_s # => "Hello, world!"
