Cargo.toml is the source of truth for active workspace members. Some crate directories are intentionally present on disk but excluded from the workspace.

Active Libraries

• lxmf-wire (crates/libs/lxmf-core): message/payload/identity primitives.
• lxmf: umbrella crate for lxmf-sdk and lxmf-wire.
• lxmf-sdk: host-facing client API (start/send/cancel/status/configure/poll/snapshot/shutdown).
• rns-embedded-runtime: node-centric embedded runtime facade with lifecycle, event, and managed std driver support.
• rns-embedded-ffi: C ABI for embedded/manual-tick compatibility and the v1 node-centric API.
• rns-embedded-core: shared embedded/runtime types and fixtures.
• reticulum-rs: umbrella crate for the Reticulum stack crates.
• reticulum-rs-core (crates/libs/rns-core): Reticulum cryptographic and packet primitives.
• reticulum-rs-transport (crates/libs/rns-transport): transport + iface + receipt/resource API.
• reticulum-rs-rpc (crates/libs/rns-rpc): RPC request/response/event contracts and bridges.
• test-support: schema/fixture validation and integration-test helpers.

Active Applications

• lxmf-cli
• reticulumd
• rns-tools

Bootstrap

Recommended:

make bootstrap

Direct script form:

./tools/scripts/bootstrap-dev.sh

Verification-only mode:

./tools/scripts/bootstrap-dev.sh --check --skip-smoke

Build and Validation

cargo check --workspace --all-targets
cargo test --workspace
cargo clippy --workspace --all-targets --all-features --no-deps -- -D warnings
cargo doc --workspace --no-deps
./tools/scripts/check-boundaries.sh

or via xtask:

cargo xtask ci
cargo xtask release-check
cargo xtask package-daemon-bundle --version 0.1
cargo xtask api-diff
cargo xtask python-impl-bench-compare
cargo xtask python-impl-bench-compare --profile report
cargo xtask python-impl-bench-report

For fast local iteration on one binary, prefer narrow commands:

make check-bin PKG=lxmf-cli BIN=lxmd
make run-bin PKG=rns-tools BIN=rnsd ARGS="--help"
make package-daemon-bundle VERSION=0.1
make python-lxmd-smoke

Binaries

• lxmf-cli
• lxmd
• reticulumd
• rncp, rnid, rnir, rnodeconf, rnpath, rnpkg, rnprobe, rnsd, rnstatus, rnx

Run examples:

cargo run -p lxmf-cli -- --help
cargo run -p reticulumd -- --help
cargo run -p rns-tools --bin rnx -- e2e --timeout-secs 20

Release Bundles

cargo xtask package-daemon-bundle builds the host-native lxmd and reticulumd binaries, generates lxmd.example.config, copies README.md, and writes a release archive under target/release-bundles/. The command emits .zip bundles on Windows and .tar.gz bundles on macOS/Linux.

On macOS, Gatekeeper may quarantine a downloaded release bundle because the project does not currently ship signed/notarized binaries. If that happens, remove the quarantine attribute after extracting the archive:

xattr -dr com.apple.quarantine /path/to/lxmd-daemon-<version>-macos-arm64
chmod +x /path/to/lxmd-daemon-<version>-macos-arm64/lxmd
chmod +x /path/to/lxmd-daemon-<version>-macos-arm64/reticulumd

Embedded Node FFI

• Header: crates/libs/rns-embedded-ffi/include/rns_embedded_ffi.h
• Guide and example: crates/libs/rns-embedded-ffi/README.md
• Stable core contract: lifecycle, status, capability probe, send/broadcast, subscriptions, structured errors
• Compatibility surface: legacy manual tick, raw wire ingress/egress, low-level queueing
• Extension surface: numeric extension IDs validated by docs/fixtures/embedded/public-node-api-v1/extension-ids.json
• v1 node-centric API: rns_embedded_v1_node_new/start/stop/restart/get_status/send/broadcast/set_log_level/subscribe_events
• legacy compatibility API remains available for manual tick, raw wire ingress/egress, and low-level queueing

Linux daemon setup (systemd)

The following installs a long-running lxmd service. lxmd also launches reticulumd, so a single unit is enough for most deployments.

1. Install binaries (from source)

cargo build --release -p lxmf-cli -p reticulumd
sudo install -m 0755 target/release/lxmd /usr/local/bin/lxmd
sudo install -m 0755 target/release/reticulumd /usr/local/bin/reticulumd

2. Create a dedicated service user and daemon directories

sudo useradd --system --create-home --shell /usr/sbin/nologin lxmd
sudo mkdir -p /etc/lxmf/lxmd /etc/lxmf/reticulumd /var/log/lxmf
sudo chown -R lxmd:lxmd /etc/lxmf /var/log/lxmf

3. Create a starting config file for lxmd

sudo mkdir -p /etc/lxmf/lxmd
sudo chown lxmd:lxmd /etc/lxmf/lxmd
sudo -u lxmd /usr/local/bin/lxmd --exampleconfig > /etc/lxmf/lxmd/config
sudo chmod 600 /etc/lxmf/lxmd/config

Optional: set an explicit Reticulum config for reticulumd (instead of relying on generated defaults).

sudo cp crates/apps/reticulumd/examples/service-reference.toml /etc/lxmf/reticulumd/config.toml
sudo chown lxmd:lxmd /etc/lxmf/reticulumd/config.toml

4. Install a systemd unit for the daemon

sudo tee /etc/systemd/system/lxmd.service > /dev/null <<'EOF'
[Unit]
Description=LXMF daemon (lxmd + reticulumd)
After=network-online.target
Wants=network-online.target

[Service]
Type=simple
User=lxmd
Group=lxmd
WorkingDirectory=/etc/lxmf/lxmd
ExecStart=/usr/local/bin/lxmd --config /etc/lxmf/lxmd/config --rnsconfig /etc/lxmf/reticulumd/config.toml
Restart=on-failure
RestartSec=5
StandardOutput=journal
StandardError=journal
Environment=RUST_LOG=info

[Install]
WantedBy=multi-user.target
EOF

If you are not using /etc/lxmf/reticulumd/config.toml, remove --rnsconfig /etc/lxmf/reticulumd/config.toml from ExecStart and run only with --config.

5. Enable and start the service

sudo systemctl daemon-reload
sudo systemctl enable --now lxmd.service
sudo systemctl status lxmd.service --no-pager

6. Tail logs and verify health

sudo journalctl -u lxmd.service -f

Using the official GitHub release binaries

Latest release artifacts are published at:

https://github.com/FreeTAKTeam/LXMF-rs/releases

1. Open the release page and download the package for your platform.

2. Linux/macOS

tar -xzf lxmd-daemon-<version>-linux-amd64.tar.gz
tar -xzf lxmd-daemon-<version>-macos-arm64.tar.gz

3. Windows

Expand-Archive lxmd-daemon-<version>-windows-x86_64.zip .

4. Run directly for validation

./lxmd --help
./reticulumd --help

5. Generate a starter lxmd config and follow the same daemon setup flow as above

./lxmd --exampleconfig > /tmp/lxmd.config

If you are using Linux and the Linux daemon guide above, point --config at the downloaded config file and keep binaries in place via your package manager path or your custom install path.

Notes

• If sccache is installed and you want to use it, set RUSTC_WRAPPER=sccache before building.
• Cross-language benchmark configuration lives in tools/benchmarks/python_impl.toml, and the operating runbook is docs/runbooks/python-impl-benchmarking.md.
• For daemon-level mixed-runtime smoke coverage, make python-lxmd-smoke launches a Rust lxmd node and an installed Python lxmd node together.
