App::Rad

App::Rad is a Perl module that provides a powerful and convenient framework for developing command-line applications. It simplifies the process of creating reusable subroutines from Perl one-liners that can be called directly by users. The module also offers an interface to streamline common command-line tasks.

To get started, the SYNOPSIS provides an example of the smallest working application, called myapp.pl. The code is straightforward, consisting of just two lines that utilize the App::Rad module to run the program. Running this script provides direct access via the command line.

The next step is to create custom functions. Suppose you add a simple function like 'hello' to myapp.pl. The component is already functional and can be called from the command line. The Available Commands section in the command-line output now lists 'hello'.

The commands can be further refined by adding a customized help message for each command. This is accomplished through the 'Help()' attribute. Once added, running the script will now show the customized message for each command.

App::Rad provides many more features to extend your applications, enabling flexibility in every command's behavior. With App::Rad's embedded help, argument and options parsing, configuration files, and other features, apps can be customized to individual requirements.

Finally, the 'bar' command example provides usage of options and arguments to the program. On executing the code, the output shows the customized message with the appropriate response. Using App::Rad's many features, developers can develop and refine complex command-line apps effortlessly.
