I have a directory which contains multiple Tools (one folder per tool). Each of these tool directories, contains multiple folders (1 folder per version).

tool1

     -- ver1

     -- ver2



 tool2

     --ver1

     --ver2

And I have a tool, that use this cache dir. I want to autocomplete the possible tools/versions in this manner:

./my_bin TOOL:VERSION

I use this complete function:

for dir in $cache_dir/*; do

    if [[ -d $dir ]]; then

        tool=$(basename "$dir")

        for version in $dir/*; do

            if [[ -d $version ]]; then

                ver=$(basename "$version")  



                array+="${tool}:${ver}  "   <<-------------



            fi

        done

    fi

done



COMPREPLY=($(compgen -W "$(echo "${array[*]}")" -- "${COMP_WORDS[-1]}"))

this command let me to autocomplete by showing all the Tool:Version couples, in the cache dir.

My question is, how can I show only the available Tools first, add the ':' separator automatically, and then show the available versions for this tool ?

It's very important for me to respect the Tool:Version format in the command argument.
