CLI applications are extremely handy to use. Building out a lot 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 the 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
Check out the video tutorial where I give some basic examples of the various features of cobra.
