dmenu menu with spaces?

Rasi · 2013-01-12 14:38:16

I am trying to create a dmenu, that runs specific commands on each entry. but i fail to use entries with spaces.
This is how i am trying to archive it, without success, i might add:

#!/bin/bash
prog="
test
test with space
"

cmd=$(dmenu <<< "$prog")

case ${cmd%% *} in

    test)   notify-send "foo" ;;
    test with spaces)  notify-send "bar"
;;
   *)      exec "'${cmd}'"  ;;
esac

what would be a better solution?

I used an associative array in my power-script:

#!/bin/bash

declare -A actions=(
    ['poweroff']='systemctl poweroff'
    ['hibernate']='systemctl hibernate'
    ['suspend']='systemctl suspend')

chosen=$(printf "%s\n" "${!actions[@]}" | dmenu) || exit 1

${actions[$chosen]}

this is nice.. but is it possible to define variables beforehand that can be used in the actual command?

TIME=3000
FILEMASK=%Y-%m-%d-@%H-%M-%S-scrot.png
function notify() {
  notify-send -u low --hint=int:transient:1 -t ${1} "Scrot" "${2}"
}

declare -A actions=(
    ['1. Quick Fullscreen']='scrot -d 1 "$FILEMASK" && notify ${TIME} "Screenshot saved"'

doesnt work

#!/bin/bash

list="test\ntest with space"

cmd=$(echo -e $list | dmenu)
echo $cmd

What if you use double quotes when assigning array's items?

declare -A actions=(
    ['1. Quick Fullscreen']="scrot -d 1 "$FILEMASK" && notify ${TIME} "Screenshot saved""

since declare opens a subshell this wont work either. too bad, it looks much cleaner

anyway, i was able to solve my good old case - here the whole script:
