## NOTE this script is used:
##      a. for building docker image
##      b. in action-jdate

function dl_xtract {
    mkdir -p "$temp_dir"/sources
    wget --tries=inf -O "$tar_file" "$1"  ## --tries=inf or --tries=0 for infinite retrying
                                          ## because downloading is sometimes not easy when building images
    tar -xf "$tar_file" -C "$temp_dir"/sources
    rm "$tar_file"
}

## needed because user is root when creating docker image, and non-root in GitHub Actions
(( UID > 0 )) || is_root='true'

temp_dir="$(mktemp -d /tmp/jdate_tmp_XXXXXX)"  ## NOTE a. do NOT replace -d with --directory
                                               ##         because mktemp on Alpine was seen to only accept -d
                                               ##      b. Alpine requires at least six Xs.
                                               ##         any modifications you make to the template,
                                               ##         make sure to do the same in the clean-up section in dockerfiles
