Discern
Discern is, like its predecessors DiscordOverlayLinux and Discover-overlay, a Discord overlay for linux.
This one is written in Rust as a project to acclimatise myself to using rust for real projects but so far is a lesson in how to self induce headaches.
While previous projects gave a plethora of user options and tweaks this one aims for a 'one-size-fits-all' in each module.
Current targets
| Target | Binary | Description |
|---|---|---|
| discern | Generic binary that will read in ENV variables and make a best-guess at what the user will want. Assumes graphical views only, no plans to best-guess terminal versions | |
| x11 | discern-x11 | GTK on x11. Uses combination of highest layer, undecorated window, xshape and xinputshape to draw over top of desktop. |
| wlroots | discern-wlroots | GTK on wayland. Uses wlroots LayerShell to draw over top of desktop |
| rpc | discern-rpc | terminal application to poll or alter discord state |
| statefile | discern-statefile | terminal or daemon application to dump current state to a file or pipe. |
| gamescope | discern-gamescope | Cairo on XCB. Uses X11 XAtom to mark as overlay window for use in gamescope |
| clispam | discern-clispam | terminal application to output all communication raw to terminal. Useful for debugging |
By default all targets are compiled at once.
To choose a specific target to compile:
cargo clean
cargo build --features "wlroots" --no-default-features
Ideas & Plans
Ideally, the plan is to eventually modularise the project so we can cover a lot more area.
- X11 Overlay ✓
- Wayland/wlroots Overlay ✓
- OpenGL & Vulkan injectors
- Gamescope specific mode (✓) with autostart (Systemd job?)
- CLI polling of Discord state ✓
Plans to move over?
Currently there are no plans to move users of my previous projects to this one. Unless this really hits the ground running I do not expect it to reach feature parity much less improve.
Installing

Did you really need to make another Discord overlay?
Technically it's not, yet.
