Add DataWeave to DataSonnet transpiler in camel-jbang#22157
Conversation
Add a `camel transform dataweave` CLI command that converts MuleSoft DataWeave 2.0 scripts into equivalent DataSonnet .ds files, enabling easier migration of Mule integrations to Apache Camel. The transpiler includes: - Hand-written recursive descent parser for DataWeave 2.0 syntax - AST-based conversion to DataSonnet with Camel CML functions - Support for field access, operators, type coercion, null handling, collection operations (map/filter/reduce/flatMap/groupBy/orderBy), string operations, if/else, var/fun declarations - Unsupported constructs flagged with TODO comments - 43 unit tests covering all conversion patterns CLI usage: camel transform dataweave --input flow.dwl --output flow.ds camel transform dataweave --input src/mule/ --output src/resources/ camel transform dataweave -e 'payload.name default "unknown"' Depends on PR #22156 (camel-datasonnet CML enhancements).

- Fix emitLambda: String.join was missing paramNames argument - Fix emitStringLit: remove double-escaping of backslashes - Fix startsWith/endsWith: use c.startsWith/c.endsWith from camel.libsonnet (DataSonnet std doesn't have these) - Fix orderBy: use c.sortBy from camel.libsonnet instead of std.sort - Fix min/max: use c.min/c.max from camel.libsonnet - Flag abs/round/sqrt as TODO (not available in DataSonnet std) - Remove unused KEYWORDS set from lexer - Add tests for startsWith, endsWith, escape preservation Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Add *.dwl to the license-maven-plugin excludes list since the plugin does not have a comment style definition for DataWeave files. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
