kicad-ipc-rs

MIT-licensed Rust client library for the KiCad IPC API.

Maintainer workflow: see CONTRIBUTIONS.md.

Status

Alpha. v0.1.1 released.

• Async API (default): implemented and usable.
• Sync/blocking wrapper API (feature = "blocking"): implemented with full async parity.
• Real-world user testing: still limited.
• Issues and PRs welcome.

Usage

Async API (Default)

Cargo.toml:

[dependencies]
kicad-ipc-rs = "0.1.1"
tokio = { version = "1", features = ["macros", "rt"] }

use kicad_ipc_rs::KiCadClient;

#[tokio::main(flavor = "current_thread")]
async fn main() -> Result<(), kicad_ipc_rs::KiCadError> {
    let client = KiCadClient::connect().await?;
    client.ping().await?;
    let version = client.get_version().await?;
    println!("KiCad: {}", version.full_version);
    Ok(())
}

Sync API (Blocking)

Enable the blocking feature and use KiCadClientBlocking for synchronous callers:

Cargo.toml:

[dependencies]
kicad-ipc-rs = { version = "0.1.1", features = ["blocking"] }

use kicad_ipc_rs::KiCadClientBlocking;

fn main() -> Result<(), kicad_ipc_rs::KiCadError> {
    let client = KiCadClientBlocking::builder().connect()?;
    client.ping()?;
    let version = client.get_version()?;
    println!("KiCad: {}", version.full_version);
    Ok(())
}

Implementation notes:

• Blocking calls run through a dedicated Tokio runtime thread.
• Requests are serialized through a bounded queue.
• Runtime teardown is graceful: in-flight work drains before worker exit.

Protobuf Source

This crate ships checked-in Rust protobuf output under src/proto/generated/.

• Consumers do not need KiCad source checkout or git submodules.
• Maintainers regenerate bindings from KiCad upstream via the kicad git submodule.
• Current proto pin: KiCad 10.0.0-rc1.1 (KICAD_API_VERSION = 10.0.0-rc1.1-0-gc7c84125).

Maintainer refresh flow:

git submodule update --init --recursive
./scripts/regenerate-protos.sh

The regeneration tool also stamps KICAD_API_VERSION from the KiCad submodule git revision.

Local Testing

• CLI runbook: /Users/milindsharma/Developer/kicad-oss/kicad-ipc-rs/docs/TEST_CLI.md
• CLI help: cargo run --features blocking --bin kicad-ipc-cli -- help

Runtime Compatibility Notes

• KiCad version (kicad-ipc-cli version): 10.0.0 (10.0.0-rc1)

Commands wrapped in this crate but currently unhandled/unsupported by this KiCad build:

Command	Runtime status	Notes
RefreshEditor	AS_UNHANDLED	KiCad responds no handler available for request of type kiapi.common.commands.RefreshEditor.

Runtime-verified operations include:

• CreateItems
• UpdateItems
• DeleteItems

KiCad v10 RC1.1 API Completion Matrix

Legend:

• Implemented = wrapped in current Rust client (src/client.rs).
• Not yet = exists in proto, not wrapped yet.
• Command messages only (request payloads); helper/response messages excluded.
