text list to 2d array and pick subarray item in bash

[blumenwesen]

I have a text list that is divided into 2D arrays and I want to use zenity to pick out a subarray.

TEXT

Code: Select all

"words1 string0" "words1 string1" "words1 string3"\n"words2 string0" "words2 string1" "words2 string3" : "words2 string4" "words2 string5" "words2 string6" : "words2 string7" "words2 string8" "words2 string9"\n"words3 string0" "words3 string1" "words3 string3" : "words3 string4" "words3 string5" "words3 string6"

The arrays are separated by line breaks, the subarrays are separated by colons.

2D

Code: Select all

val[0,0]="words1 string0" "words1 string1" "words1 string3"
val[1,0]="words2 string0" "words2 string1" "words2 string3"
val[1,1]="words2 string4" "words2 string5" "words2 string6"
val[1,2]="words2 string7" "words2 string8" "words2 string9"
val[2,0]="words3 string4" "words3 string5" "words3 string6"

MY cryptic code to convert text to 2d

Code: Select all

z=$(cat "FILE"); 
isz=$IFS; IFS=[$'\x0A']; z=($z); 
IFS=$isz; 
for (( y=0; y<${#z[@]}; y++ )); do 
    x="${z[$y]//[ ][:][ ]/$'\x0A'}"; 
    IFS=[$'\x0A'] read -d "" -ra x <<< "$x"; 
    for (( w=0; w<${#x[@]}; w++ )); do 
        ar0["$y,$w"]="${x[$w]}"; 
    done; 
done
echo "${ar0[0,2]}"

zenity array = 1-3 und subarrays = (array1 = 1, array2 = 3, array3 = 2)

Since array1 only has 1 subarray with 3 items, only 1 should be displayed.
Array2 has 3 subarrays with 9 items, so 3 should be displayed.
Array3 with 2 subarrays and 6 items, 2 should be displayed.

Zenity should be adjusted dynamically so that array1 does not display 3 subarrays as in this example.

Code: Select all

z=$(zenity --forms --title="TITLE" --add-combo="" --combo-values="1|2|3" --add-combo="" --combo-values="1|2|3"); echo "$z"

I should probably add that the text arrays are music paths and the whole thing is a file in which many playlists can be saved as paths.
I apologize for the cryptic variables and that I overwrote some of them and didn't replace [$'\x0A'] with "\n".
But how can something so complex be written much more simply if it is to be dynamic?!
It's working now anyway.

Code: Select all

"/home/user/song 1.avi" "/home/user/song 2.mkv" "/home/user/song 3.mp4"
"/home/user/song 4.mp4" "/home/user/song 5" "/home/user/song 6.mp4" : "/home/user/song 7.mp4" "/home/user/song 8.mp4" "/home/user/song 9.mp4" : "/home/user/song 10" "/home/user/song 11.mp4" "/home/user/song 12.mp4"
"/home/user/song 13.avi" "/home/user/song 14.mkv" "/home/user/song 15.mkv" : "/home/user/song 16.mkv" "/home/user/song 17.mp4" "/home/user/song 18.mp4"

Code: Select all

z=$(zenity --forms --title="MUSIC" --add-list="" --list-values="rock|dark|hipo");
 [[ $z == "rock" ]] && z=0; [[ $z == "dark" ]] && z=1; [[ $z == "hipo" ]] && z=2; 
y=$(cat "file");  y="${y/${y/[$'\x0A']*/}[$'\x0A']/}"; y="${y/[$'\x0A']${y/*[$'\x0A']/}/}"; 
isa=$IFS; IFS=[$'\x0A']; y=($y); IFS=$isa; 
for (( x=0; x<${#y[@]}; x++ )); do 
w=${y[$x]//[ ][:][ ]/$'\x0A'}; IFS=[$'\x0A']; w=($w); IFS=$isa; 
for (( v=0; v<${#w[@]}; v++ )); do 
[[ $z == $x ]] && eval "IFS=[\$'\\\x0A']; ar${z}[$v]=\${w[\$v]}; IFS=\$isa"; done; done; y=""; 
for (( x=0; x<$(eval "echo \${#ar${z}[@]}"); x++ )); do y+="$x|"; done; 
y=$(zenity --forms --title="TITEL" --add-list="" --list-values="$y");
z=$(eval "echo \${ar${z}[${y}]}"); 
IFS=[$'\x0A']; arr=( $(echo "${z//[\"][ ][\"]/$'\x0A'}") ); IFS=$isa; 
mpv --no-terminal --loop-playlist=inf "${arr[@]//[\"]/}" & disown

Or boring script .

Code: Select all

z=$(zenity --forms --title="MUSIK" --add-list="" --list-values="rock|dark|hipo"); 
[[ $z == "rock" ]] && z=0; [[ $z == "dark" ]] && z=1; [[ $z == "hipo" ]] && z=2; 
y=$(cat "file"); y="${y/${y/[$'\x0A']*/}[$'\x0A']/}"; y="${y/[$'\x0A']${y/*[$'\x0A']/}/}"; 
readarray -t y < <(echo "$y"); 
readarray -t x < <(echo "${y[$z]//[ ][:][ ]/$'\x0A'}"); 
y=""; for (( x=0; x<${#x[@]}; x++ )); do y+="$x|"; done; 
y=$(zenity --forms --title="TITEL" --add-list="" --list-values="$y");
readarray -t w < <(echo "${x[$y]//[\"][ ][\"]/$'\x0A'}"); 
mpv --no-terminal --loop-playlist=inf "${w[@]}"
