sjgandClaude Opus 5 cfaeb6ee15 [docs](trx-rs): generate the example config and correct the manual

trx-rs.toml.example was maintained by hand and had fallen well behind: no
[[rigs]], no [[remotes]], no [timeouts], no bandplan or decode-history
settings, and a [frontends.http].default_rig_id that had been renamed.

Generate it from the config structs instead, so a new field shows up the moment
it exists, and add a test that fails when the checked-in copy drifts:

    cargo run -p trx-config --example generate_example

Section comments come from a small table; a section without an entry is still
emitted, so forgetting a comment can never drop a setting from the example.

The manual was wrong about the basics.  It listed five config search paths, none
of which the loader has ever looked at (the real order is ./trx-rs.toml → XDG →
/etc), called --print-config output "fully commented" when it carries no
comments at all, and documented a TRX_PLUGIN_DIRS variable no code reads.  It
also still described [frontends.rigctl].port as the bind port years after
rig_ports replaced it.  Fixed, and the new configuration features are written
up alongside.

trx-rs

A modular amateur radio control stack written in Rust.

trx-rs splits radio hardware access from user-facing interfaces so you can run rig control, SDR DSP, decoding, audio streaming, and web access as separate, composable pieces.


Backends	Yaesu FT-817, Yaesu FT-450D, SoapySDR
Frontends	Web UI, rigctl-compatible TCP, JSON-over-TCP
Decoders	AIS, APRS, CW, FT8, RDS, VDES, WSPR
Audio	Opus streaming between server, client, and browser

Quick Start

1. Install dependencies

Debian / Ubuntu

sudo apt install build-essential pkg-config cmake libopus-dev libasound2-dev
# Optional — SDR support
sudo apt install libsoapysdr-dev

Fedora

sudo dnf install gcc pkg-config cmake opus-devel alsa-lib-devel
# Optional — SDR support
sudo dnf install SoapySDR-devel

Arch Linux

sudo pacman -S base-devel pkgconf cmake opus alsa-lib
# Optional — SDR support
sudo pacman -S soapysdr

macOS (Homebrew)

brew install cmake opus
# Optional — SDR support
brew install soapysdr

See Build Requirements in the wiki for details on each library.

Note: cmake is required even when a system Opus library is installed. The audiopus_sys crate probes for Opus via pkg-config; if it is not found (or pkg-config is unavailable), it falls back to compiling a vendored copy of Opus with CMake. A missing cmake therefore fails the build with is cmake not installed? rather than a missing-Opus error.

2. Build

cargo build --release

Build without SDR support: cargo build --release --no-default-features

3. Configure

Run the interactive setup wizard to generate config files for your station:

./target/release/trx-configurator

The wizard walks you through rig selection, serial port detection, audio settings, and frontend options, then writes trx-server.toml and trx-client.toml.

Alternatively, copy trx-rs.toml.example — a commented example covering every setting — and edit it by hand:

cp trx-rs.toml.example trx-rs.toml
./target/release/trx-server --check-config --config trx-rs.toml

--check-config reports everything wrong with a config without starting anything. --print-config prints the same settings without comments.

4. Run

./target/release/trx-server --config trx-server.toml
./target/release/trx-client --config trx-client.toml

A single trx-rs.toml can configure both: the server reads its [trx-server] section and the client reads [trx-client].

Open the configured HTTP frontend address in a browser (default http://localhost:8080).

How It Works

graph TD
    SDR1["SDR #1"] & SDR2["SDR #2"] <-->|USB| S1["trx-server A"]
    SDR3["SDR #3"] & FT817["FT-817"] <-->|USB / serial| S2["trx-server B"]

    S1 <-->|"JSON-TCP :4530"| C1["trx-client"]
    S1 -->|"Opus-TCP per rig"| C1
    S2 <-->|"JSON-TCP :4530"| C1
    S2 -->|"Opus-TCP per rig"| C1

    C1 <-->|internal channels| F1["Web UI :8080"]
    C1 <-->|internal channels| F2["rigctl :4532"]

Each trx-server owns one or more rigs and runs DSP, decoding, and audio capture locally. A trx-client connects to any number of servers over TCP and exposes them through a unified set of frontends.
