Generated files are (re)written every run; static templates are copied alongside and re-copied only if missing (so handwritten edits to templated scaffolding are preserved). | + +### Role flags + +| Flag | Purpose | +|---|---| +| `--server` | Emit server dispatch (matches request name to handler, deserialises, calls handler, serialises response). Pair it with an `ipc::IpcServer` from ipc-runtime. | +| `--client` | Emit a typed client class/struct with one method per command. Pair it with an `ipc::IpcClient` (C++) or the equivalent Rust/Zig/TS binding. | +| `--package ` | TS only. Emit a complete package wrapper around the generated async client. The wrapper launches a native service binary, connects over UDS or SHM, and resolves the binary from an override path, environment variable, installed arch package, or local `build//` directory. | +| `--uds` | Rust/Zig only. Copies the `Backend` trait template (and `error.rs` for Rust) into `` so consumers can plug ipc-runtime — or any custom transport — behind the generated client. The flag name is historical: the trait is transport-agnostic. | +| `--ffi` | Rust/Zig only. Adds the `ffi_backend` template (a thin wrapper exposing the generated client over a C ABI for embedding in other languages). | + +### Naming flags + +| Flag | Purpose | +|---|---| +| `--prefix ` | Type prefix applied to generated type names (`CircuitProve`, etc.). Auto-detected from the schema if omitted. | +| `--strip-method-prefix` | TS only. Drops the prefix from client *method* names: `bbCircuitProve()` → `circuitProve()`. Types keep the prefix. | + +### C++-specific flags + +| Flag | Purpose | +|---|---| +| `--cpp-namespace ` | C++ namespace, e.g. `my::service`. Default: lowercased prefix. | +| `--cpp-wire-namespace ` | Inner namespace for wire types, default `wire`. | +| `--cpp-include-dir ` | Include-path prefix for cross-includes between generated files, e.g. `myservice/generated`. Leave unset when generated files are in the same directory as their consumer. | + +### Other + +| Flag | Purpose | +|---|---| +| `--curve-constants` | TS only. Also emit `curve_constants.ts` with bn254/grumpkin/secp moduli & generators for schemas that need curve constants. | +| `--skeleton ` | One-shot scaffolding: writes a `_handlers.{ts,rs,zig,cpp}` stub, `main`, and a build file into `` if they don't already exist. Skipped on subsequent runs. | +| `--package-name ` | TS package mode only. Package name to write into the generated wrapper `package.json`. | +| `--binary-name ` | TS package mode only. Native service binary name to launch. | +| `--binary-env-var ` | TS package mode only. Environment variable that can override the binary path. Defaults to `_PATH`. | +| `--package-transports ` | TS package mode only. Comma-separated transports supported by the generated wrapper. | +| `--ipc-runtime-dependency ` | TS package mode only. Dependency spec for `@aztec/ipc-runtime`, e.g. a release version or local `file:` dependency in examples. | + +## Worked examples + +Paths below are illustrative — consumers commit their own schema next to the +C++ server that owns the wire format and supply absolute or relative paths on +the command line. + +### TypeScript client, with curve constants + +```sh +src/generate.ts \ + --schema /path/to/myservice_schema.json \ + --lang ts \ + --out /path/to/output/generated \ + --client \ + --prefix MyService --strip-method-prefix --curve-constants +``` + +Produces `api_types.ts`, `async.ts`, `sync.ts`, `curve_constants.ts`.

The package exports a +`MyServiceService.spawn(...)` helper that launches the native binary and wraps +the generated async client. `scripts/prepare_arch_packages.sh` turns +`build//` directories into per-architecture npm packages +matching the binary resolution path. + +### C++ server + client, under a project sub-include path + +```sh +src/generate.ts \ + --schema /path/to/myservice_schema.json \ + --lang cpp \ + --out /path/to/myservice/generated \ + --server --client \ + --cpp-namespace my::ns --prefix MyService \ + --cpp-include-dir myservice/generated +``` + +Produces `myservice_types.hpp`, `myservice_ipc_client.{hpp,cpp}`, and +`myservice_ipc_server.hpp`. Cross-includes use the supplied `--cpp-include-dir` prefix +(`#include "myservice/generated/myservice_types.hpp"`).

UDS/SHM transport is provided by the +`ipc-runtime` Rust crate; the consumer chooses which to use via the path +suffix passed at runtime. The skeleton flag also writes a one-time +`myservice_handlers.rs`, `main.rs`, `Cargo.toml`, and `generate.sh` into the +skeleton dir so a new service crate is buildable on first run. + +### Zig client + server + +```sh +src/generate.ts \ + --schema /path/to/myservice_schema.json \ + --lang zig \ + --out /path/to/output/generated \ + --server --client --uds --ffi \ + --prefix MyService +``` + +Produces `myservice_types.zig`, `myservice_client.zig`, +`myservice_server.zig`, plus `backend.zig` and `ffi_backend.zig`. Consumers +`@import("ipc_runtime")` for transport. + +## Adding a new service + +1. **Define the C++ command structs** in your service's `.hpp`, each with + `MSGPACK_SCHEMA_NAME` and `SERIALIZATION_FIELDS(...)`.

Commit it next to the C++ + source that defines it (e.g. alongside the `Command` / `Response` + headers). This is the wire-format source of truth. +3. **Wire your consumer's build to invoke `src/generate.ts`** with the flags + above, passing the absolute path to the committed schema and the desired + output directory. Generated files go under a `generated/` directory which + is gitignored by convention. +4. **Wire transport.** On the C++ server side, instantiate an + `ipc::IpcServer` via `ipc::make_server(path)` (from ipc-runtime) and feed + it the codegen-emitted `make__handler(...)`. On the client side + (any language), point an `ipc::IpcClient` / equivalent at the same path + and wrap it with the codegen-emitted client. +5. **Run `./bootstrap.sh test`** in `ipc-codegen/` to confirm the codegen and + cross-language wire-compat tests still pass. + +## Schemas are the source of truth + +The JSON schema is the wire contract between client and server. Consumers +commit it next to the C++ server that defines the underlying +`SERIALIZATION_FIELDS`, so the file lives close to what it describes and +tracks with that code. Whenever a server-side command changes, refresh the +JSON snapshot by running ` msgpack schema` against the rebuilt +binary and committing the diff. Diverged schemas are a CI failure (each +consumer is responsible for guarding its own snapshot). + +Each generated file embeds a `SCHEMA_HASH` so callers can detect at +connection time that their bindings predate the server. + +## Wire-format contract + +`echo_example/schema/golden/*.msgpack` is a frozen set of byte-level +fixtures covering every relevant msgpack encoding boundary (variable-width +ints, fixstr/str8/str16, bin8/bin16, optional `Some`/`None`, empty +containers, multi-byte UTF-8). The per-language golden tests +(`echo_example/{rust,ts}/...`) both decode the fixtures and re-encode +round-trip — pinning down canonical msgpack output across implementations. + +If you intentionally change the wire format, run +`./bootstrap.sh update_goldens` and review the diff.

fix(ipc): foundation review remediation Addresses the full ipc-codegen/ipc-runtime review (68 findings): - runtime: NAPI lifecycle (close/join, TSFN leak, sync deadline), zero-length response deadlock, u64 timeout truncation, max-frame guards, crash cleanup, unified constants, UDS timeouts, new cpp/rust/ts test suites - codegen: schema validation (required error variant, name pairing, reserved words), unified server error wrapping, zig comptime handler injection, uniform --strip-method-prefix, skeleton/dead-code removal - wire fixes: rust Option/[bytes;N] serde, ts u64 bigint bridging + bin32 guards, zig signed-int tolerance, cpp union ordering + PrimAlias so schema reflection of generated types round-trips aliases - tests: golden corpus extended (error variant pinned) with cpp/zig runners, error-path + boundary-value steps in every matrix combo, FFI compile checks --- ipc-codegen/SCHEMA_SPEC.md | 21 +- ipc-codegen/bootstrap.sh | 23 +-
