Fang is a Go library designed to simplify the creation of command-line interface (CLI) applications. It addresses the common challenges of formatting output, generating documentation, and managing application metadata. Fang aims to provide a batteries-included solution for developers using Cobra, a popular Go library for building CLIs, by offering features to enhance the user experience and streamline development workflows.
Fang offers fully styled help and usage pages, improving the visual presentation of CLI applications. It automates versioning and generates manpages and shell completions, reducing boilerplate code. Its themeable design allows for customization to match project branding, while silent usage output ensures a cleaner user experience during error conditions.
