Google HCLS Whistle Data Transformation Language

Summary

This defines a syntax designed to express mappings of data from one structure to another.

This syntax is transpiled into a configuration file for the Data Harmonization Mapping Engine which can then execute the mappings.

The engine accepts data in JSON format and outputs it in JSON format. For information on the syntax, look at the included documents in the docs folder.

Building and Testing

TL;DR

Run build.sh

Details

This project is a go module. It can be built and tested with go build and go test.

There is an additional go module in the test directory, which runs some integration tests using the mapping engine.

The whistle_*.go files in the parser directory are generated by ANTLR. If you modify the grammar (Whistle.g4) file make sure to re-run generate_grammar.sh or build.sh.
