+:artifactId: camel-datasonnet
+:description: To use DataSonnet scripts in Camel expressions or predicates.
+:since: 3.7
+:supportLevel: Preview
+include::{cq-version}@camel-quarkus:ROOT:partial$reference/languages/datasonnet.adoc[opts=optional]
+
+*Since Camel {since}*
+
+Camel supports https://datasonnet.com/[DataSonnet] transformations to allow an
Expression or Predicate to be used in the Java DSL or
xref:manual::xml-configuration.adoc[XML
+Configuration].
+
+To use a DataSonnet expression use the following Java code:
+[source,java]
+---------------------------------------
+... datasonnet("someDSExpression") ...
+---------------------------------------
+
+== Example
+
+Here is a simple example using a DataSonnet expression as a predicate in a
Message Filter:
+
+[source,java]
+------------------------------------------------------------------------------------------------
+// lets route if a line item is over $100
+from("queue:foo")
+ .filter(datasonnet("ds.arrays.firstWith(body.lineItems, function(item)
item > 100) != null"))
+ .to("queue:bar")
+------------------------------------------------------------------------------------------------
+
+And the Spring DSL:
+
+[source,xml]
+-----------------------------------------------------------------------------
+<route>
+ <from uri="queue:foo"/>
+ <filter>
+ <datasonnet>ds.arrays.firstWith(body.lineItems, function(item) item >
100) != null</datasonnet>
Review comment:
Ah yeah there may be some mistakes in other parts of the docs. However
you need to escape this in XML, but then they are harder to read, > vs > -
but we can leave this as-is.
How is it going with all the other review comments?
