Claus Ibsen commented on CAMEL-4028:
------------------------------------

Taarig that is a great start.

We need tests for camel-spring as well as you can use <simple> in there. And we need tests that uses custom prefix/suffix tokens.

In the SimpleExpression you need to add attributes for prefix/suffix so they can be configured in XML DSL:
{code:xml}
<simple prefix="[" suffix="]">[body] is cool</simple>
{code}

Likewise we should add support for configuring those prefix/suffix tokens on a global level so you dont have to provide custom all the time. But I wonder what a good way would be for that?

In Java it would be to configure the SimpleLanguage
{code}
SimpleLanguage simple = (SimpleLanguage) context.resolveLanguage("simple");
simple.setPrefix("[");
simple.setSuffix)"]");
{code}

But in XML DSL we may want a nice way of doing that in the XSD.
Currently you should be able to do it as a <bean> tag

{code:xml}
<bean id="simple" class="...SimpleLanguage">
  <property name="prefix" value="["/>
  <property name="suffix" value="]"/>
</bean>
{code}

> The simple language uses ${ } tokens by default. However groovy uses those for its GString. So we have a clash. Even if you use $simple{ } instead in Groovy then you have a clash.
> So we should add support for configuring the tokens so you can remedy the GString clash in Groovy.
