-------------------------------------

Here is the help of the prototype implementation Ive produced:

{code}
ServiceMix-5.0.0:7412003A@root> groovy --help
DESCRIPTION
        sncf:groovy

        Run an interactive Groovy session (use ":exit" to return to Karaf console)

SYNTAX
        sncf:groovy [options]

OPTIONS
        --command, -c
                Execute the given Groovy command, without entering interactive shell
                Exclusive with the -s (--script) and -l (--load) options
        --help
                Display this help message
        --enable-package-loading
                Enable packages pre-loading (disabled by default since very slow in OSGi)
        --reset-shell
                Reset the Groovysh shell (new instance)
        --reference, -r
                Resolve and assign OSGi service(s) in Groovy shell variables, in the form
                serviceName1=serviceInterface1(ldapFilter1),serviceName2=serviceInterface2(ldapFilter2),...
                The LDAP filter is optional. Only the best matching service found is returned.
                (defaults to )
        --import, -i
                Imports the specified packages or classes into Groovy, in the form qualifiedName1,qualifiedName2,...
                (defaults to )
        --load, -l
                Execute the given Groovy script list, in the form scriptUrlOrPath1,scriptUrlOrPath2,...
by loading them to an interactive Groovy shell
                Equivalent to the Groovy :load command. Exclusive with -c (--command) and
-s (--script) options
        --variable, -v
                Import specific Karaf variables in Groovy shell, in the form variableName1,variableName2,...
                (defaults to )
        --script, -s
                Execute the given Groovy script, in a separate Groovy dedicated (non interactive)
interpreter
                Exclusive with -c (--command) and -l (--load) options
{code}

>             Project: Karaf
>          Issue Type: New Feature
>          Components: karaf-shell
>            Reporter: Denis Jouvin
>            Assignee: Jean-Baptiste Onofré
>            Priority: Minor
>              Labels: Groovy, Groovysh, Karaf, ShellCommands
>
> The idea is to integrate Groovy into Karaf as an alternative scripting and/or interactive
shell language.
> The Groovysh shell then would allow to get OSGi service reference, or Blueprint/Spring
context references. 
> This open some possibilites like exploratory programming, scripting, live tests or analysis,
etc.
