Bash function to shorten interactions with Terraform Workspaces from the command line.

tfw_bash.sh

## The commands for working with terraform workspaces can be a little verbose, this just makes it easier to interact
## with the workspaces commands.  It relies on `getops`, @see: https://wiki.bash-hackers.org/howto/getopts_tutorial
##
## This function can be added to your .bashrc or .zshrc.

tfw() {
  # when no workspace is given, it's expected we're listing
  if [ -z "$1" ]; then
    terraform workspace list
    return $?
  fi

  # check for options
  while getopts ":d:" opt; do
    case $opt in
      # delete flag specified, delete the given workspace
      d)
        terraform workspace delete "$OPTARG"
        return $?
        ;;
      :)
        echo "Option -${OPTARG} requires a workspace name to delete." >&2
        return 1
        ;;
    esac
  done

  # Either select or create the workspace (this becomes idempotent)
  terraform workspace select "$1" 2> /dev/null || terraform workspace new "$1"
}
