ATD project - Static Types for Json APIs

ATD stands for Adaptable Type Definitions. It is a syntax for defining cross-language data types. It is used as input to generate efficient and type-safe serializers, deserializers and validators.

Target programming languages currently supported:

• C++: atdcpp
• DLang: atdd
• Java: atdj
• OCaml, Melange: atdgen
• Python: atdpy
• Scala: atds
• TypeScript: atdts

Export to other interface description languages (IDLs):

• JSON Schema: atdcat -jsonschema

Tools to work with ATD files:

• atdcat: check syntax, reformat, expand inherited definitions, export to JSON Schema, ...
• atddiff: compare two revisions of a given ATD interface and report incompatibilities.

All can installed with opam e.g.

$ opam install atdgen
