Cobra

A modern CLI Commander for go

While developing Hugo I became disappointed with the interface limitations flags alone provide. A quick look at virtually any command line application (ls, grep, less, etc) reveals that most applications overuse flags to do everything and often allow conflicting flags to be applied. Even though hugo is relatively simple, we already had the ability to stack flags that didn’t make sense. You can set the port using –port but this only has an effect if you also specified –server.
