Show two things side by side using catimg (like in neofetch)

I am trying to create something like neofetch does using bash.

I want to show one image on the right and one ascii art (using the cat << EOF myascii EOF command) So that I can show a logo and a text on the other side.

I want to use it as my login welcome screen when I ssh some of my machines.

So I was able to show the ascii art by doing :

cat << EOF

 _____         _   
|_   _|       | |  
  | | ___  ___| |_ 
  | |/ _ \/ __| __|
  | |  __/\__ \ |_ 
  \_/\___||___/\__|
                   
                   

EOF

And showing my image using catimg myimage.png

However I try to show them both side by side. I tried using pr. pr -m -t <(catimg) <(cat mytestfile.txt) but it doesn't work and it cuts my ascii art.

It's the same using the paste command.

Was anyone able to do it. If yes how ? My ascii art is quiet long too so without it to be cutted it would be awesome.

Thanks for your help.

Produce txt file by merging ouput of catimg and figlet

Instead of real merge, I will simply put both output at correct place by using ANSI escape code

{
    mapfile aa < <(figlet -w40 $text)
    printf "%s" "${aa[@]}"
    catimg -w40 "$image" |
        sed "\$!s/^/\o33[40C/;1s/^/\o33[${#aa[@]}A/"
} >outputfile.txt

figlet-catimg

This could be written as a function:

mkTextImage() {
    local aa width=${COLUMNS} prcent=50 text image lwidth rwidth ffont
    while [ "${1::1}" == "-" ] ;do
        case $1 in 
            -w) shift;width=$1;shift;;
            -p) shift;prcent=$1;shift;;
            -f) shift;ffont="-f $1";shift;;
        esac
    done
    text="$1" image="$2"
    printf -v lwidth %.0f $(
         bc -l <<<"$width/100*$prcent")
    rwidth=$((width-lwidth))
    mapfile aa < <(figlet -w$lwidth $ffont $text)
    printf "%s" "${aa[@]}"
    catimg -w$rwidth "$image" |
        sed "\$!s/^/\o33[${lwidth}C/;1s/^/\o33[${#aa[@]}A/"
}

And reversed:

(Nota: This work while catimg length stay bigger than figlet length)

mkImageText () { 
    local aa fl width=${COLUMNS} prcent=50 text image lwidth rwidth ffont
    while [ "${1::1}" == "-" ] ;do
        case $1 in 
            -w) shift;width=$1;shift;;
            -p) shift;prcent=$1;shift;;
            -f) shift;ffont="-f $1";shift;;
        esac
    done
    image="$1" text="$2"
    printf -v lwidth %.0f $(bc -l <<<"$width/100*$prcent")
    rwidth=$((width-lwidth))
    mapfile aa < <(catimg -w$lwidth "$image")
    printf "%s" "${aa[@]}"
    printf "\e[$((${#aa[@]}-1))A"
    mapfile fl < <(figlet -w$rwidth $ffont "$text")
    printf "\e[${lwidth}C%s" "${fl[@]}"
    printf "\e[$((${#aa[@]}-${#fl[@]}-1))B"
}

catimg-figlet

From there, regarding your comment: try using 42% of 80 columns width for image:

mkImageText -f small -p 42 spongebob.png "Sponge Bob"

or

mkTextImage -f small -p 58 "Sponge Bob" spongebob.png

Will render:

Gif animation of both commands on 80x25 terminal

Then you could try using -f smblock option, or modify functions to use toilet instead of figlet...
