Possible to parse multiple long options?

[msabramo]

I have this code:

while getopts_long ':remoteHost: toDir:' OPTKEY; do
    case ${OPTKEY} in
        'remoteHost')
            REMOTE_HOST="${OPTARG}"
            ;;
        'toDir')
            TO_DIR="${OPTARG}"
            ;;
        '?')
            echo "INVALID OPTION -- ${OPTARG}" >&2
            exit 1
            ;;
        ':')
            echo "MISSING ARGUMENT for option -- ${OPTARG}" >&2
            exit 1
            ;;
        *)
            echo "UNIMPLEMENTED OPTION -- ${OPTKEY}" >&2
            exit 1
            ;;
    esac
done

and I'm invoking my script with arguments: --remoteHost=somehost --toDir=/tmp/foo

The result is:

INVALID OPTION -- remoteHost

The result is the same if I use as arguments: --remote-host somehost --to-dir /tmp/foo

How do I specify that both --remoteHost and --toDir are valid long options?

Hmmm, it seems that it works as long as I have some short options also -- e.g.:

while getopts_long 'r:t: remoteHost: toDir:' OPTKEY; do

I guess the bug is that multiple long options don't work if you define no short options.

This works: while getopts_long ': remoteHost: toDir:' OPTKEY; do
