> camel-core - Compiled simple language
> -------------------------------------
>
> Key: CAMEL-15704
> URL: https://issues.apache.org/jira/browse/CAMEL-15704
> Project: Camel
> Issue Type: New Feature
> Components: camel-core
> Reporter: Claus Ibsen
> Assignee: Claus Ibsen
> Priority: Major
> Fix For: 3.7.0
>
>
> Lets look at if we can provide an alternative to simple language that gets
> compiled during initialization of Camel. However for compilation then the
> csimple would need to have type information when using OGNL method calls as
> simple is dynamic and uses _duck typing_.
> The camel-joor should be more focused on pure Java code script and not a new
> simple language. jOOR also have some limitations such as cant run with
> fat-jar style for Spring Boot. Also it wont work on native compiled and it
> uses a reflective method call to call the joor script.
> For csimple we can look at
> - byte buddy
> - java assist
> - scan source code via a maven plugin and detect simple language (we do this
> for the camel-route-parser) and then source code generate in src/generated
> which then gets compiled with the regular compiler. And then those code can
> be loaded the same way we do with configurers etc which means no reflection.
