> Key: CAMEL-24908
> URL: https://issues.apache.org/jira/browse/CAMEL-24908
> Project: Camel
> Issue Type: Improvement
> Components: camel-jbang
> Reporter: Claus Ibsen
> Priority: Major
> Fix For: 4.24.0
>
>
> Follow-up from the benchmark work (CAMEL-24886), for the next round rather
> than 4.23: a model writing a transformation has no way to try it. It writes
> the mapping into the route, saves, reloads, reads the log, and repeats; every
> mistake costs a reload cycle, and a wrong shape (a list where a map was
> meant, a field name that does not exist in the document) is only visible as
> an exception.
> What the authoring tools are missing, in the order they would help:
> * evaluate an expression against a sample document and return the value with
> its Java type, for every language the examples use (jsonpath, jq, simple,
> groovy, xpath, datasonnet), which is CAMEL-24907
> * a mapping preview: the source document in, the expression or the Groovy
> script, the produced document out, side by side, so a person and a model can
> see the shape they are about to write
> * the same for the data formats: unmarshal a sample with the format and its
> options and show what the body becomes (a Map, a List of Maps, a POJO),
> because the body type is what the next step trips over (see CAMEL-24844)
> * the errors of a failed mapping named in terms of the document, "the
> document has no field customer at the top level, it has orderId, customer is
> under customer.id", rather than a Jackson or JsonPath stack trace
> Camel is an integration framework; mapping and manipulating data is most of
> what people write in it, and it is the part where an agent has the least
> feedback today.
