CLI applications are extremely handy to use. Building out alot of the nice features that good CLI apps have can be a bit time consuming though.

At least, it was, until cobra was created and that changed everything.

Cobra is a go package that can be utilized to create very robust CLI applications with very little effort.

It provides an impressive list of features:

• Subcommand-based CLIs
• POSIX-compliant flags (short/long versions)
• Nested subcommands
• Global, local, and cascading flags (explained in video)
• Application and command generator
• Auto suggestions on command typos
• Automatic help generation
• Automatic help flag recognition
• Generates shell autocompletion for bash, zsh, fish, and powershell
• Generates documentation, such as man pages
• Command aliases
• Integrates very well with viper
