hcli is @jtagcat's wannabe urfave/cli@v3 written from the ground up, hoping to become the next major release. It relies on harg, a feature-complete argument parser.
hcli attempts to be as user-friendly as possible, while encouraging more advanced Go patterns and best practices. All of that while staying elegant with standard libraries and newer language syntax.
Work in progress. #1583 is loosely tracking this.
