- Global, local and cascading flags
- Easy generation of applications & commands with cobra init appname & cobra
add cmdname
- Intelligent suggestions (app srver... did you mean app server?)
- Automatic help generation for commands and flags
- Automatic help flag recognition of -h, --help, etc.
- Automatically generated bash autocomplete for your application
- Automatically generated man pages for your application
- Command aliases so you can change things without breaking them
- The flexibility to define your own help, usage, etc.
- Optional tight integration with viper for 12-factor apps
