Claus Ibsen reassigned CAMEL-25470:
-----------------------------------
Assignee: Claus Ibsen
> camel-dataweave - $ shorthand with .@attr, .*field or ? is mis-converted
> without a TODO
> ---------------------------------------------------------------------------------------
>
> Key: CAMEL-25470
> URL: https://issues.apache.org/jira/browse/CAMEL-25470
> Project: Camel
> Issue Type: Bug
> Reporter: Claus Ibsen
> Assignee: Claus Ibsen
> Priority: Major
> Fix For: 4.23.0
>
>
> The DataWeave to DataSonnet converter mis-parses the $ lambda shorthand when
> it is followed by an XML attribute selector (.@attr), a multi-value selector
> (.*field) or an existence check (?). parseDollarShorthand() consumes the dot
> but only collects identifiers, so the rest of the expression is parsed
> wrongly and no TODO is counted, which means DatasonnetLanguage's fail-fast
> check (CAMEL-25323) does not catch it.
> Examples on main:
> ||DataWeave||Emitted today||
> |payload.items map $.@id|std.map(function(x) x., body.items) - invalid
> Jsonnet|
> |payload.items map $.*Item|std.map(function(x) x., body.items) * Item|
> |payload.items reduce ($$ + $.*price)|acc + item * price - silently wrong|
> |payload.items reduce ($$ + $.@qty)|parse error: expected RPAREN but found AT|
> |payload.items filter $.price?|? binds to the whole filter expression|
> In addition, a reduce shorthand body ($$ / $) that uses if/else or default
> (e.g. payload.items reduce ($$ + $.price default 0)) is not supported and is
> emitted as a TODO.
> The explicit lambda form (item, acc = 0) -> acc + item.@qty is converted
> correctly.
> Follow-up to CAMEL-25324 and CAMEL-25323.
