cmdr
A POSIX-compliant Go library for parsing command-line arguments and managing hierarchical configurations.
What is cmdr?
Cmdr is a Go library for building command-line interface (CLI) applications with a focus on parsing arguments and managing configurations. It provides a robust foundation for developers to create CLI tools with features like subcommands, flag parsing, and integration with external configuration sources. The library emphasizes clean, maintainable code and flexibility, allowing developers to choose the command-building approach that best fits their project while ensuring stability and performance.
Go developers building CLI tools who need advanced features like hierarchical configuration management, shell autocompletion, and manpage generation. It is particularly suited for those creating complex CLI applications with multiple subcommands and requiring integration with various configuration sources.
Developers choose Cmdr over alternatives for its POSIX-compliant parser with support for compact flag combinations, flexible command-building styles (traditional stream calls, concise builders, struct-based definitions), and seamless integration with hedzr/store for hierarchical configuration management. Its unique selling points include smart help with typo suggestions using Jaro-Winkler distance and automatic generation of shell autocompletion scripts and manpages.
