How do I take the key/values from an associative array and display them in a Zenity list dialog?

Example:

#!/bin/bash

get_final_bookmarks_choice(){
    if [ ${#matched_bookmarks[@]} -eq 1 ]; then
        # open_bookmarks_command
        return
    fi
    # guard clause.  If no bm found.
    if [ -${#matched_bookmarks[@]} -eq 0 ]; then 
        msg='No bookmarks match found.'
        notify-send "$msg"; echo "$msg"
        return
    fi

    bm_url=$(zenity --entry --title="Multi matches found" \
    --text="Choose bookmark" \
    --column="Name" --column="URL" \

    # Key/value dictionary here.
    )
    # Return the key.
    echo "$key returned here."
}


declare -A matched_bookmarks
matched_bookmarks=(
    ['match 1']='http://match1.com'
    ['match 2']='http://match2.com'
    ['match 3']='http://match3.com'
)

bm_name="$(get_final_bookmarks_choice)"

bm_url="${matched_bookmarks[$bm_name]}"

echo "Bookmarks URL:$bm_url"

CodePudding user response：

You have to use array, not associative array, as argument to zenity command:

dialogarray=()
for idx in "${!matched_bookmarks[@]}";do
    dialogarray =("$idx" "${matched_bookmarks[$idx]}")
done

zenity --list --title="Multi matches found" --text="Choose bookmark" \
     --column="Name" --column="URL" "${dialogarray[@]}"

Here is my version of your script:

#!/bin/bash

get_final_bookmarks_choice(){
    local -n Assoc=$1 Result=$2
    case ${#Assoc[@]}  in
        1 ) # open_bookmarks_command
            Result=${!Assoc[*]}
            return
            ;;
        0 ) # guard clause.  If no bm found.
            msg='No bookmarks match found.'
            notify-send "$msg"
            echo "$msg"
            exit 1
            ;;
        * )
            local -a zenDialog=()
            local idx
            for idx in "${!Assoc[@]}";do
                zenDialog =("$idx" "${Assoc[$idx]}")
            done
            read -r Result < <(
                zenity --list --title="Multi matches found" \
                       --text="Choose bookmark" \
                       --column="Name" --column="URL" "${zenDialog[@]}" )
    esac
}


declare -A matched_bookmarks
matched_bookmarks=(
    ['match 1']='http://match1.com'
    ['match 2']='http://match2.com'
    ['match 3']='http://match3.com'
)

get_final_bookmarks_choice matched_bookmarks bm_name

bm_url="${matched_bookmarks[$bm_name]}"

echo "Bookmarks URL:$bm_url"
