Two changes for 0.7.0: BREAKING (D-Bus): the service is renamed from org.gnome.Strata to dev.edu4rdshl.Strata. The org.gnome.* namespace is reserved for official GNOME software; Strata is third-party, so it now uses the reverse-DNS of its own domain (matching the strata@edu4rdshl.dev UUID). Bus name, object path (/dev/edu4rdshl/Strata), and interface (dev.edu4rdshl.Strata.Manager) all change. Daemon and extension are updated together; only external busctl scripts / non-GNOME front-ends that hard-coded the old name need updating. The GSettings schema (org.gnome.shell.extensions.strata) is unchanged - that namespace is correct for GNOME Shell extension settings. Fix recursion: the theme-context 'changed' handler reloaded light.css, but load_stylesheet itself emits 'changed', so it fed back into itself and hit "too much recursion" - flooding the journal and spinning the CPU on screen unlock (which restyles widgets and fires 'changed'). The subscription is removed; light.css is loaded once. Dark/light switching is unaffected (it is the panel's class toggle, not this load). A GNOME Shell theme switch no longer auto-re-applies the sheet, which is recoverable by re-enabling. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

Guidelines for AI agents working on this codebase.

|
## Repository layout
|
|
|
|
```
|
|
strata-daemon/ Rust daemon (tokio, zbus, rusqlite)
|
|
strata@edu4rdshl.dev/ GNOME Shell extension (GJS) - pure JS, no binary
|
|
schemas/ GSettings schema XML
|
|
ui/ Panel and item widgets
|
|
contrib/systemd/ systemd user service unit for distro packaging
|
|
ARCHITECTURE.md In-depth design document
|
|
```
|
|
|
|
## Core principle
|
|
|
|
"JS draws, Rust thinks." The extension must never block the GNOME Shell
|
|
compositor. All heavy work (hashing, storage, search, thumbnails) lives in
|
|
the daemon. The extension only renders and forwards events.
|
|
|
|
## Build
|
|
|
|
```bash
|
|
# Build daemon + compile schemas
|
|
make
|
|
|
|
# Install daemon binary to ~/.local/bin (must be in PATH)
|
|
make install-daemon
|
|
|
|
# Install extension to ~/.local/share/gnome-shell/extensions/
|
|
make install
|
|
```
|
|
|
|
## Lint
|
|
|
|
```bash
|
|
cargo clippy --manifest-path=strata-daemon/Cargo.toml
|
|
```
|
|
|
|
No linter is configured for GJS. Follow the existing code style.
|
|
|
|
## Deploy to a test VM
|
|
|
|
```bash
|
|
# Build and copy daemon binary to VM
|
|
cargo build --release --manifest-path=strata-daemon/Cargo.toml
|
|
scp strata-daemon/target/release/strata-daemon fedoradev:~/.local/bin/
|
|
|
|
# Sync extension (JS only)
|
|
rsync -a strata@edu4rdshl.dev/ fedoradev:~/.local/share/gnome-shell/extensions/strata@edu4rdshl.dev/ --exclude='.git'
|
|
ssh fedoradev 'glib-compile-schemas ~/.local/share/gnome-shell/extensions/strata@edu4rdshl.dev/schemas/'
|
|
# Then log out and back in (Wayland) or Alt+F2 r (X11)
|
|
```
|
|
|
|
## Key files
|
|
|
|
| File | Purpose |
|
|
|---|---|
|
|
| `strata-daemon/src/main.rs` | Entry point, Wayland monitor, GJS submit task, `process_change`/`process_bytes` |
|
|
| `strata-daemon/src/dbus_service.rs` | D-Bus interface, `Limits` struct, all D-Bus methods |
|
|
| `strata-daemon/src/db.rs` | SQLite schema, FTS5, insert, prune, search, thumbnail |
|
|
| `strata-daemon/src/config.rs` | Data dir, DB path (`~/.local/share/strata/clipboard.db`) |
|
|
| `strata@edu4rdshl.dev/extension.js` | Daemon lifecycle (PATH lookup + systemd detection), clipboard ingest, focus tracking, `_pushConfig` |
|
|
| `strata@edu4rdshl.dev/ui/panel.js` | Popup panel, lazy-load pagination, search, `_pageSize`, theme class toggle (`_applyTheme`) |
|
|
| `strata@edu4rdshl.dev/stylesheet.css` | Dark theme (default, auto-loaded by GNOME) |
|
|
| `strata@edu4rdshl.dev/light.css` | Light theme overrides, scoped under `.strata-theme-light` |
|
|
| `strata@edu4rdshl.dev/ui/clipboardItem.js` | Individual row widget |
|
|
| `strata@edu4rdshl.dev/prefs.js` | Preferences window (Adw) |
|
|
| `strata@edu4rdshl.dev/dbus.js` | D-Bus proxy definition and XML interface |
|
|
| `contrib/systemd/strata-daemon.service` | systemd user unit for distro packaging |
|
|
|
|
## D-Bus interface summary
|
|
|
|
Service `dev.edu4rdshl.Strata`, object `/dev/edu4rdshl/Strata`, interface `dev.edu4rdshl.Strata.Manager`.
|
|
|
|
Methods: `GetHistory(offset u32, limit u32) -> json s`,
|
|
`SearchHistory(query s, limit u32) -> json s`,
|
|
`GetThumbnail(id s) -> png_bytes ay`,
|
|
`GetItemContent(id s) -> (mime_type s, content ay)`,
|
|
`SetClipboard(id s)`, `DeleteItem(id s)`, `ClearHistory()`,
|
|
`SetConfig(max_history u32, max_text_bytes u32, max_image_bytes u32)`,
|
|
`SubmitItem(mime s, data ay)`, `Shutdown()`.
|
|
|
|
Signals: `ItemAdded(id s, mime_type s, preview s)`, `ItemDeleted(id s)`, `HistoryCleared()`.
|
|
|
|
## GSettings keys
|
|
|
|
`max-history`, `page-size`, `max-text-mb`, `max-image-mb`, `theme`, `panel-position`,
|
|
`panel-width`, `panel-max-height`, `keyboard-shortcut`, `move-activated-to-top`,
|
|
`excluded-apps`.
|
|
|
|
`theme` is `auto`/`light`/`dark`. `auto` follows `org.gnome.desktop.interface
|
|
color-scheme`. Light styling lives in `light.css`, scoped under a
|
|
`.strata-theme-light` class the panel toggles on its root box; `extension.js`
|
|
loads/unloads `light.css` via the St theme context. New non-`stylesheet.css`
|
|
CSS files must be added to the `pack` target as `--extra-source` (only
|
|
`stylesheet.css` is auto-included by `gnome-extensions pack`).
|
|
|
|
## Conventions
|
|
|
|
- No `--` em-dashes, no emojis in code comments or docs.
|
|
- Rust: use `tracing::info!`, `tracing::warn!`, `tracing::error!` (qualified path, not bare imports). No `println!` in daemon code.
|
|
- GJS: `console.log('[Strata] ...')` / `console.error('[Strata] ...')` prefix for all extension logs.
|
|
- Size limits travel as bytes over D-Bus. MB conversion happens extension-side.
|
|
- `Ordering::Relaxed` is intentional on `Arc<AtomicUsize>` limits (advisory, not critical path).
|
|
- Never execute clipboard content. Writes go through `wl-clipboard-rs` (`copy_multi`) in the daemon, never via shell subprocess or `eval`.
|
|
- Excluded apps list is checked before storing any clipboard item.
|
|
- Ingest paths are mutually exclusive by environment: on GNOME the monitor cannot bind (Mutter exposes neither data-control protocol) so ingest is GJS `SubmitItem`; on wlroots the built-in monitor is the path.
|
|
- List queries (`get_history_page`, `search_history`) return `content_text` truncated to `PREVIEW_CHARS` via `substr`; full content is served only by `GetItemContent` for paste-back.
