Overview

easy-cli is a java library for easy command line argument parsing. It can also print help message which shows the options available for the command line tool.

It is annotation based, which makes it easier to define and use the parsed arguments.

• Open source
• Easy to use
• Supports different types of options
  • Short and long options (e.g. ls -r and ls --reverse)
    • POSIX like options (e.g. ls -ltr Test.java)
    • GNU like long options (e.g. ls --reverse --format=commas)
  • With space separator between the option and value (e.g. --option value or -o value)
• Generates help message
