如何在go中定义标志组？

Question

I'm trying to make use of the flag package. My whole issue is that I need to specify groups/multiple values for the same parameter. For example I need to parse a command as below:

 go run mycli.go -action first -point 10 -action
 second -point 2 -action 3rd -point something

I need to retrieve each group of action/point param. Is it possible?

The flag package won't help you. Closest you'll get is the os package:

[jadekler@Jeans-MacBook-Pro:~/go/src]$ go run temp.go asdasd lkjasd -boom bam -hello world -boom kablam

[/var/folders/15/r6j3mdp97p5247bkkj94p4v00000gn/T/go-build548488797/command-line-arguments/_obj/exe/temp asdasd lkjasd -boom bam -hello world -boom kablam]

So, the first runtime flag key would be os.Args[1], the value would be os.Args[2], the next key would be os.Args[3], and so on.
