Bare task names list for completion

[rafi]

It would be nice to have a way to list task names without colors and formatting so it could be consumed by a bash/zsh/fish completion script for the task name. Something like robo -q ?

Adding this to robo.yml:

templates:
  list: |-
    {{range .Tasks}}{{.Name}}{{ print "\n" }}{{end}}

And sourcing this bash completion:

#/usr/bin/env bash
_robo_completion() {
  if [ "${#COMP_WORDS[@]}" != "2" ]; then
    return
  fi
  COMPREPLY=($(compgen -W "$(robo)" -- "${COMP_WORDS[1]}"))
}

complete -F _robo_completion robo

Works nicely. But it's annoying adding the list template in each robo.yml file.

Nice use case, perhaps we should use github.com/alecthomas/colour, from it's TTY() docs:

$ go doc colour.TTY
func TTY(w io.Writer) Printer
    TTY creates a Printer that colourises output if w is a terminal, or strips
    formatting if it is not.

Other solutions might be to add completions automatically for shells like zsh and bash, or a --json flag that will output JSON?

I'll see if I have 30m this weekend to whip up a PR.

Actually haven't thought about it a bit, it seems like -q is the simplest way to go about it, similar to how docker outputs verbose info but only lists the IDs with -q.

Exactly my thoughts @yields, same as docker lists only the IDs with -q.
