A desktop server browser for Arma Reforger, built on the reforgermods.net v2 API. Live server list with search, sort and filters; a detail inspector with population history and mod readiness; measured ICMP latency; favorites, recents and settings; and direct joining through Steam. Tauri 2 and Rust, with a Preact frontend that builds to 80 KB of JavaScript in one chunk. Logic lives in rfm-core, which has no Tauri dependency and is tested directly; src-tauri is the window, the command surface and the wiring. Packaged for the public beta: a per-user NSIS installer, a portable .exe and an Arch package, with signature-verified background updates on Windows and a release pipeline that builds from a tag. The artifacts are not yet Authenticode-signed — that is wired and waiting on an Azure Trusted Signing identity, and docs/distribution.md says so plainly rather than letting anyone discover it at the SmartScreen dialog.

Discord Rich Presence — setup
Status: live. Application id 1552757014474784898 is set in
src-tauri/src/presence.rs.
The launcher appears on a user's Discord profile the way DZSA Launcher does for DayZ — "Playing reforgermods.net launcher", with artwork, the server being viewed, and a button linking to the site.
The application id supplies the name Discord displays, so the Discord
application must be named exactly reforgermods.net launcher. Artwork still has
to be uploaded for the large image to appear; see step 3.
What it looks like
┌────┐ reforgermods.net launcher
│ RM │ Viewing [OGR2] Old Guard Revival 2
└────┘ 12/128 players
[ Get the launcher ]
- Application name — from the Discord application. This is the headline and the reason the application must be created with exactly the right name.
- Details / state — from
rfm_core::presence. - Large image — the asset keyed
logoin the application's Rich Presence art. - Button — "Get the launcher" →
https://reforgermods.net.
Remaining setup
Create the application— done, id1552757014474784898.- Confirm the application name is exactly
reforgermods.net launcher. This string is what every user's friends list shows; it cannot be changed per-client, and it is the whole promotional value of the feature. - Upload the artwork. Under Rich Presence → Art Assets, add
brand/reforger-mods-app-icon.pngwith the keylogo, matchingLARGE_IMAGE_KEYinsrc-tauri/src/presence.rs. Until this exists the text and button still show, but the card has no image.
The application id is a public identifier, not a secret — it ships in every Discord game integration and is visible in any client's traffic. It is safe in the repository. Do not put the application's client secret or bot token anywhere near this project; Rich Presence needs neither.
Trying it without editing the source

Behaviour
| Situation | Result |
|---|---|
| No application id configured | Presence is disabled; no thread, no socket. |
| Discord not running | Connection fails quietly, retried at most every 30s. |
| Discord restarts | Next update reconnects and republishes the current state. |
| User turns it off in Settings | Presence is cleared immediately. |
Presence runs on its own thread and is never awaited from a command, so Discord being slow, absent or broken cannot stall the UI.
Privacy
Presence is on by default, since being visible is the point, but it is a visible toggle in Settings because it broadcasts the name of the server being viewed to the user's Discord friends. Nothing else is published: no account, no install identifier, no IP, no mod list.
Why the text rules are tested
crates/rfm-core/src/presence.rs builds the strings and is unit tested, because
server names are untrusted text from the API and Discord is unforgiving:
detailsandstatecap at 128 characters, and Discord silently drops a field under two characters rather than reporting an error.- Truncation is by character. Cutting a multi-byte glyph in half yields invalid UTF-8 and Discord rejects the entire payload — so a server named in Japanese or full of flag emoji would blank the presence rather than shorten it.
- Control characters are stripped and whitespace collapsed, so a server name containing newlines cannot reformat the presence card.
The "reforgermods.net launcher" line is ours and is never taken from remote data, so a server cannot name itself something that impersonates the launcher.
