mainargs
A small, dependency-free library for command-line argument parsing in Scala, used by Ammonite and Mill.
What is mainargs?
MainArgs is a lightweight, dependency-free library for parsing command-line arguments in Scala. It allows developers to define CLI interfaces by annotating methods and case classes with `@main` and `@arg`, eliminating the need for boilerplate configuration code. It solves the problem of quickly building command-line tools with support for sub-commands, custom types, and flexible error handling.
Scala developers building command-line applications, tools, or scripts who want a simple, annotation-based argument parser without external dependencies.
Developers choose MainArgs for its zero-dependency design, ease of use with annotations, and seamless integration with Scala idioms like case classes. It offers a cleaner alternative to more verbose libraries like Scopt or Case App, with features tailored for real-world use in projects like Ammonite and Mill.
