Feature: Discord Rich Presence by hitblast · Pull Request #139 · Mrmayman/quantumlauncher

hitblast · 2026-02-05T09:08:03Z

TL;DR: I'm trying to get Discord's Rich Presence connected with the launcher using a tiny library that I'm working on alongside this PR. Here is the link in case if you want to check out.

As of now, I'll be working on it actively until I hit compatibility on all three major platforms, till then I have some goals which I'll put here:

Initial commit with a working demo.
Obey the message model of iced.
Add rich presence update events to places of interest as a final touch.
Possibly add a setting to enable/disable rich presence?
Add supervisor for reconnecting the IPC client in sync with Discord opening/reopening.
Implement a "Presence" settings tab for managing the core Discord Presence client.

More will be added as the feature continues. I'd like your consideration on this as it'd be a tough time deciding what messages and states to include this. Currently I've only modified the Launcher state to support this, which I assumed is shared globally (I might be wrong here).

Cheers.

Hey, @hitblast i looked at implementation of discord ipc client , and it appears to be having MSRV of 1.85.1 (verfied by cargo-msrv)
the launcher official MSRV is pinned down to 1.82.0

hitblast · 2026-02-05T12:16:14Z

@Sreehari425 Oh, forgot to adjust the edition to 2021; will shortly push commits to the library to handle that.

my thoughts:

so far it seems decent in terms of structure like you asked, it's fine
i'd prefer if you made lots of stuff async (especially in Launcher::new, idk if that's blocking tho). Using tokio's spawn_blocking for non async functions. Responsiveness is a priority
can you sort out windows support too later as it's a key requirement?
i had some ideas for a detailed presence config screen in launcher settings where you can customize stuff. What do you think?
i may be slow or late to respond/review sometimes, so sorry about that in advance. I'm just super busy so please don't mind if i'm late to anything

can you sort out windows support too later as it's a key requirement?

I was thinking about the async part, as its mostly just UnixStream being handed off to separate threads in the deep level. I'll work on implementing spawn_blocking. Also Windows support will be sorted as soon as tomorrow I think since I've been working on a pipe idea. Also, for any other ideas, I guess we could continue this on the Discord server. I've already left a message for your convenience.

Looking forward!

Update: I'm currently a little busy and will return to this PR once I'm done.

hitblast · 2026-02-14T08:46:13Z

@Mrmayman @Sreehari425 A little update; I've implemented a base configuration for the rich presence functionality which includes a few different things now:

Modification to the message_handler module so that there are two new functions for initializing and updating the rich presence on startup or anywhere inside the codebase.
Task::perform implementation as promised since a pipe might not be available as always and therefore if not, QuantumLauncher will skip it.

I'll need some review over my implementation since I am a bit rusty with iced but hopefully we can build upon this to integrate it into several other views and functions of the launcher.

Mrmayman · 2026-02-14T14:24:42Z

Alright i read through your code, seems okay 👍 you can continue like that

btw if you need me at any time, i'll finally be free for help with this PR and general development after next Wednesday, when my exams get over. Till then i may be a bit slow to respond or work on stuff but i'll try to help

Sure! For the most part, I'm interested about the states which you want to put rich presence updates in (for example in certain views such as the mod menu or instance selections). I'd also need some help regarding what details to put in them. That's about it.

Appreciate it.

- Move config fields to separate struct - Split message into separate `RpcMessage` - Many tweaks to data types and how it's stored - Code cleanup

+                // On disable
+                let client = self.discord_ipc_client.clone();
+                self.is_presence_running = false;
+
+                tokio::spawn(async move {
+                    if let Some(c) = client {
+                        _ = c.close().await;
+                    }
+                });


When RPC is toggled off, the code closes the client asynchronously but leaves self.discord_ipc_client populated. This keeps a stale handle around and makes it harder to reason about later updates (and interacts with in-flight DiscordIPCRunStarted/DiscordIPCPresenceSet messages). Clear self.discord_ipc_client (and consider ignoring/closing any late-started client) as part of the disable path.
