Command chaining support

[willmitchell]

Hi there, and thanks for Cobra!

Is it possible to chain commands? Imagine a super simple 'accumulator' type of program that supports 3 commands as shown below:

$ go run main.go 
Demo program related to Cobra command chaining

Usage:
  cobra_chain_ex [command]

Available Commands:
  add         Add 1 to the accumulator
  help        Help about any command
  sub         Subtract 1 from the accumulator
  total       Print the value of the accumulator

I would like to be able to chain commands like so:

$ go run main.go add add add sub total
add called
$ 

Note that only the first command is executed. Is there a way to make Cobra execute all of the commands in left to right order?

Code is here.

Thanks!

@willmitchell you could write a variadic calc command. Each argument describes an action that is done in order, so the available actions for this example is:

add
sub

This is similar to lfold in various languages. https://medium.com/zendesk-engineering/foldable-go-d74fb9cf2fc9

go run main.go calc add add sub
2

go run main.go calc --start 5 add add add add
9

Sorry this has been open for so long with little attention. As part of #1600 I'm going to closing as duplicate of #726 which is requesting the same feature effectively (multiple commands in series on the CLI).
