# The Mojom Parser The Mojom format is an interface definition language (IDL) for describing interprocess communication (IPC) messages and data types for use with the low-level cross-platform [Mojo IPC library](https://chromium.googlesource.com/chromium/src/+/main/mojo/public/c/system/README.md). This directory consists of a `mojom` Python module, its tests, and supporting command-line tools. The Python module implements the parser used by the command-line tools and exposes an API to help external bindings generators emit useful code from the parser's outputs. TODO(https://crbug.com/1060464): Fill out this documentation once the library and tools have stabilized.
