command line completion

[josacar]

It would be nice to add completion for the login and exec command to list the profiles over there.

I can do it in bash/zsh for I ask here if I should bake it in the CLI itself.

Bash completion can be like this:

#!/usr/bin/env bash

__debug()
{
    if [[ -n ${BASH_COMP_DEBUG_FILE} ]]; then
        echo "$*" >> "${BASH_COMP_DEBUG_FILE}"
    fi
}

_aws-okta () {

  local cur
  cur=${COMP_WORDS[COMP_CWORD]}
  local cmd
  cmd=${COMP_WORDS[1]}
  local prev
  prev=${COMP_WORDS[COMP_CWORD-1]}
  local profiles
  profiles=$(awk '/profile/ {print $2}' ~/.aws/config |tr -d \])
  local params
  params="--backend --debug --help --"
  local commands
  commands="add exec help login version"

  COMPREPLY=()

  case "$cmd" in
    exec)
        COMPREPLY=( $(compgen -W "${profiles}" -- "${cur}") )
        ;;
    -*)
        COMPREPLY=( $(compgen -W "${params}" -- "${cur}") )
        ;;
     *)
        COMPREPLY=( $(compgen -W "${commands}" -- "${cur}") )
        ;;
  esac
  return 0
}

complete -F _aws-okta aws-okta

awsless has a nice completion story that I think we should emulate.

See https://github.com/wallix/awless/blob/8c1a034197b873414f5f4733e14752ca6a7a7198/commands/autocompletion.go

Lets users just add something like this to their .bashrc:

source <(awless completion bash)
