go-reticulum

Go port (parity-focused) of the original Reticulum project.

This repository is maintained as a practical parity port. The current parity target is Python Reticulum 1.1.5, and the Go implementation is aligned against that version across the core library, bundled CLI utilities, examples, and parity/integration checks currently tracked in this repository. A significant part of the work was/is done with AI assistance (Codex/LLMs) for reading the reference implementation, creating parity TODOs, writing tests, and porting examples/CLI tooling.

The port is developed by a single maintainer with assistance from ChatGPT 5.1/5.2. Even though the project is covered with unit tests, integration tests, and smoke checks, unstable areas may still exist; if you run into one, please open an issue or contact the maintainer.

Goals

• Port Reticulum to Go with maximum behavioural parity.
• Keep the project testable: unit tests and selected integration tests.
• Provide CLI utilities compatible in spirit with the original ones (rnstatus, rnpath, rnid, etc.).

Repository layout

• rns/ — core library (network stack and protocols).
• cmd/ — CLI utilities (the Go equivalents of Reticulum’s “official” tools).
• examples/ — ports of Python examples (small demo programs).

How to run

Requires Go (recommended: current stable version).

How to use

Prefer using prebuilt binaries from Releases if you don’t want to build from source.

Quick start (local shared instance)

1. Start the daemon (shared instance):

go run ./cmd/rnsd -v

2. In another terminal, view status:

go run ./cmd/rnstatus -a

If you use a non-default config directory, pass it to every tool:

CFG="$HOME/.reticulum-go"
go run ./cmd/rnsd -config "$CFG" -v
go run ./cmd/rnstatus -config "$CFG" -a

CLI utilities (cmd/*)

Quick run without building:

go run ./cmd/rnsd --help
go run ./cmd/rnstatus --help

Tools overview

• rnsd — Reticulum daemon / shared instance runner. See cmd/rnsd/README.md.
• rnstatus — status display for interfaces and transport. See cmd/rnstatus/README.md.
• rnpath — path discovery and path table management. See cmd/rnpath/README.md.
• rnprobe — probe/RTT utility using receipts. See cmd/rnprobe/README.md.
• rnid — identity and crypto utility (generate/announce/encrypt/sign). See cmd/rnid/README.md.
• rnx — remote execution (listener/client, ACL, interactive mode). See cmd/rnx/README.md.
• rncp — file transfer (send/receive/fetch, ACL). See cmd/rncp/README.md.
• rnir — identity resolver stub / Reticulum initialiser (parity placeholder). See cmd/rnir/README.md.
• rnodeconf — RNode firmware/config tool (hardware-dependent). See cmd/rnodeconf/README.md.

Build a single tool:

go build -o ./bin/rnstatus ./cmd/rnstatus
./bin/rnstatus --help

Examples overview

• minimal — smallest possible init + announce loop. See examples/minimal/README.md.
• announce — destination announces + announce handler. See examples/announce/README.md.
• broadcast — plain destination “channel” broadcast. See examples/broadcast/README.md.
• link — basic link establishment + packet exchange. See examples/link/README.md.
• identify — link identification (Link.Identify) demo. See examples/identify/README.md.
• echo — receipts/proofs + RTT measurement. See examples/echo/README.md.
• ratchets — destination ratchets demo. See examples/ratchets/README.md.
• channel — message-based Channel over Link. See examples/channel/README.md.
• buffer — buffered read/write over Link Channel. See examples/buffer/README.md.
• request — request/response handlers over Link. See examples/request/README.md.
• resource — large transfers via Resource. See examples/resource/README.md.
• filetransfer — directory listing + file download over Resource. See examples/filetransfer/README.md.
• speedtest — link throughput measurement. See examples/speedtest/README.md.
• interface — add a custom interface programmatically (serial). See examples/interface/README.md.

Quick run:

go run ./examples/minimal --help
go run ./examples/link --help

Parity & docs

• Current parity target: Python Reticulum 1.1.5.
• PARITY_*.md files track any remaining or newly discovered parity drift vs the Python reference (no unrelated wishlists).
• Ideally, each parity item is closed by a code change plus a test/verification step.
• Note: the Python Reticulum supports “external interfaces” by loading <Type>.py modules from interfacepath. The Go port does not execute/load those Python modules; if such a file exists, startup will error to avoid silently running with a placeholder interface.

Disclaimer

This is a work-in-progress port: APIs, protocols, and CLI behaviour can change as parity improves.
