> Groovy and groovysh integration into Karaf console
> --------------------------------------------------
>
> Key: KARAF-5202
> URL: https://issues.apache.org/jira/browse/KARAF-5202
> Project: Karaf
> Issue Type: New Feature
> Components: karaf
> Reporter: Denis Jouvin
> Priority: Minor
> Labels: Groovy, Groovysh, Karaf, ShellCommands
>
> The idea is to integrate Groovy into Karaf as an alternative scripting and/or
> interactive shell language. Since Groovysh also uses JLine, integration is
> quite easy (pass the current Jline console/session instance to Groovysh at
> construction time). There are some class loading issues though since Groovy
> uses sometimes the TCCL even when we instruct it to use a given class loader
> (I opened a Groovy JIRA issue about that).
> The Groovysh shell then would allow to get OSGi service reference or
> Blueprint/Spring context references, or execute Karaf commands. Groovysh has
> a very nice command completion feature that enable to discover any objet
> (including OSGi service instance) API at runtime, which makes it very easy to
> play with in a dynamic environment like Karaf. In addition, its native
> closures and set operations, and very concise syntaxe, facilitates its use as
> a shell replacement.
> This open nice possibilites like exploratory programming on a live running
> Karaf instance, scripting, tests or analysis, etc.
> Another common use case is to modify a not yet parameterized value in a
> Blueprint or Spring context at runtime (you can browse or access the
> Blueprint context components, and reinstaciate them or inject properties).
