impact-com-cli

A tiny Java CLI that prints impact.com.

Built with picocli as a bonus to my application for the Java software engineer role at impact.com.

  Hi impact.com.

Options

java -jar target/impact-com-cli.jar --help

Flag	Effect
-p, --plain	Print only impact.com, no banner.
-l, --loud	Uppercase the company name.
-h, --help	picocli-generated help.
-V, --version	Print version and exit.

Why picocli

Picocli is the de-facto standard for Java CLIs — annotation-driven, supports subcommands, ANSI colors, completion scripts, and produces a --help that looks great out of the box. For a one-line program it's overkill on purpose; the goal is to show idiomatic Java tooling, not just System.out.println.
