# aster — Hyprland Bar & Notification Daemon
|
||||
|
||||
Minimal Rust status bar and notification daemon for Hyprland. Replaces colorshell with a lower system footprint. No system tray, no launcher, no wallpaper logic.
|
||||
|
||||
---
|
||||
|
||||
## Stack
|
||||
|
||||
| Crate | Purpose |
|
||||
|---|---|
|
||||
| `gtk4` | UI toolkit |
|
||||
| `gtk4-layer-shell` | Wayland layer surface anchoring |
|
||||
| `relm4` | Component architecture for GTK4 |
|
||||
| `hyprland` | Hyprland IPC (workspace events) |
|
||||
| `zbus` | D-Bus (notifications daemon) |
|
||||
| `serde` + `serde_json` | Parse pywal colors.json |
|
||||
| `tokio` | Async polling runtime |
|
||||
|
||||
---
|
||||
|
||||
## Component 1: Top Bar
|
||||
|
||||
Full-width bar anchored to the top of the screen via `gtk4-layer-shell`. Single horizontal row, three sections.
|
||||
|
||||
### Left — Workspaces
|
||||
|
||||
- Numbered workspace buttons sourced from Hyprland IPC
|
||||
- Subscribe to live workspace change events via `/tmp/hypr/$HYPRLAND_INSTANCE_SIGNATURE/.socket2.sock`
|
||||
- Active workspace highlighted with accent colour
|
||||
|
||||
### Centre — Clock
|
||||
|
||||
- Format: `HH:MM`
|
||||
- Updated every second
|
||||
|
||||
### Right — System Stats
|
||||
|
||||
Displayed left to right: CPU% → RAM% → Power draw (W) → WiFi SSID
|
||||
|
||||
| Stat | Source |
|
||||
|---|---|
|
||||
| CPU usage | `/proc/stat` delta between polls |
|
||||
| RAM usage | `/proc/meminfo` |
|
||||
| Power draw | `/sys/class/power_supply/*/power_now` or `current_now * voltage_now` |
|
||||
| WiFi SSID | Parse `iw dev` output — no NetworkManager dependency, no system tray |
|
||||
|
||||
Polled every 2 seconds.
|
||||
|
||||

|
||||
|
||||
## Component 2: Notification Daemon
|
||||
|
||||
Implements the `org.freedesktop.Notifications` D-Bus interface via `zbus`.
|
||||
|
||||
- On `Notify` call: spawn a GTK4 layer-shell popup anchored **top-right**, 20px from edge
|
||||
- Shows: app name, summary, body
|
||||
- Auto-dismisses after the hint timeout (default 5s if unset by sender)
|
||||
- Multiple notifications stack vertically downward
|
||||
- Supports `CloseNotification`
|
||||
|
||||
---
|
||||
|
||||
## Theming
|
||||
|
||||
Read `~/.cache/wal/colors.json` on startup. Reload on `SIGHUP` for live wallpaper-change integration.
|
||||
|
||||
| pywal key | Role |
|
||||
|---|---|
|
||||
| `special.background` | Bar background (with slight CSS transparency) |
|
||||
| `colors.color0` | Widget background / secondary surfaces |
|
||||
| `colors.color15` | Foreground text |
|
||||
| `colors.color1` | Accent — active workspace, highlights |
|
||||
|
||||
Apply as a GTK CSS provider at the `Display` level so the bar and all notification popups share the same palette automatically.
|
||||
|
||||
---
|
||||
|
||||
## Explicit Non-Goals
|
||||
|
||||
- No system tray (`StatusNotifierItem` / `XEmbed`)
|
||||
- No launcher or search (external tool handles this)
|
||||
- No wallpaper engine (external tool handles this)
|
||||
- No Bluetooth, volume, or media controls
|
||||

## Build Order for Claude Code
|
||||
|
||||
Follow this sequence so each step is independently testable:
|
||||
|
||||
1. **Scaffold** — `Cargo.toml` with all dependencies, module stubs, empty `main.rs`
|
||||
2. **Layer shell anchor** — blank GTK4 window pinned to top of screen; confirm it appears correctly on your setup before adding any widgets
|
||||
3. **Theme loader** — read `colors.json`, build CSS string, inject as `CssProvider` at display level
|
||||
4. **Bar layout** — three-section `Box`, no data yet, just structure with placeholder labels
|
||||
5. **Workspaces** — Hyprland IPC socket reader, live workspace buttons
|
||||
6. **Stats poller** — tokio task polling CPU/RAM/power/WiFi, sending results to bar via channels
|
||||
7. **Clock** — second-tick timer widget
|
||||
8. **Notification daemon** — zbus service on session bus claiming `org.freedesktop.Notifications`
|
||||
9. **Notification popup** — layer-shell window anchored top-right, vertical stack, auto-dismiss timer
|
||||
10. **Wire SIGHUP** — reload `colors.json` and re-inject CSS on signal
|
||||

|
||||
|
||||
## First Prompt for Claude Code
|
||||
|
||||
> Create a new Rust project called `aster`. It is a minimal Hyprland status bar and notification daemon. Start with `Cargo.toml` — I need gtk4, relm4, gtk4-layer-shell, hyprland, zbus, tokio, serde, and serde_json as dependencies. Then scaffold the module structure from the file tree in the brief and get a blank GTK4 window anchored full-width to the top of the screen with gtk4-layer-shell before adding any widgets. The layer-shell anchor is the most environment-sensitive step so I want to confirm it works on my setup first.
