The syntax of CWL is formally defined in the Semantic Annotations for Linked Avro Data (SALAD) language. Using the schema-salad-tool, a reference tool for SALAD, we can generate code such as data structures and parsers of CWL in various programming languages such as Python, Java, TypeScript, .Net, C++, and D.

This talk shows an overview of the CWL parser for D, which has been added since BioHackathon Europe 2022. Unlike the generator for other languages, the schema-salad-tool only generates the data structures, and the parser implementation is automatically deduced from the data structure at compile time by using metaprogramming features in D. It enables us to improve the CWL parsers, such as bug fixes or performance improvements, without re-generating the parsers.
