XIDL

XIDL (eXtensible IDL) is an OMG IDL-based code generator. It supports targets such as c, cpp, rust, rust-axum, and rust-jsonrpc. XIDL is plugin-capable and uses JSON-RPC as the plugin communication protocol.

Features

• Multi-language code generation from IDL
• Layered generation pipeline (typed_ast / hir / target code)
• Pluggable codegen engines via JSON-RPC
• Built-in formatting for IDL / Rust / C++ / TypeScript

Quick Start

# Build
cargo build

# Run tests
cargo test

# Generate code (example)
xidlc -l rust -o out your.idl

Built-in Targets (current)

• c
• cpp
• rust
• rust-jsonrpc
• rust-axum
• ts / typescript

Plugin Model

• During generation, xidlc starts a codegen engine based on the target language.
• Built-in engines run in-process; unknown targets can be handled by external xidl-<lang> plugins.
• Plugins communicate with the host via JSON-RPC; see xidlc/src/jsonrpc/ipc.idl for the core interface.
