Expression Language
Hello,
Is it possible for me to 'plugin' my own version of a juel language support
package (call it 'mel')? I 'd like to define a route as follows:
from("seda:q.A").filter().mel("${...}")....
If this is possible, can someone plz give me a nudge in the right general
direction as to how it can be done?
Many thanks,
Joe

Yeah for for all the scripting languages.
I created a ticket to track it:

Ah OK! Maybe we just need to patch the existing JuelLanguage to make
it easy to plugin some context-initializer thingy so you can easily
customize the variable bindings?

If its still Juel, you could just use the existing EL methods/DSL/XML
and just use Spring/Guice/Java to dependency inject the JuelLanguage
object itself.
You can plugin any language at runtime using the parameterized
language method/XML
from("...").filter().language("mel", "${....}");
Are you trying to add a totally new language; or do you just want to
configure Juel some?
