- Template sections placed above or to the right of the typing keys; the user picks any mix in settings, typing keys included - keysym keys send XKB keysyms on press, optionally repeating - Geometry lays blocks side by side with one key unit; stretch keys are resolved at layout time so composed blocks line up - Toggling a block resizes the window so keys keep their size Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

# sloposk
|
||
|
||
iPad-style floating on-screen keyboard for Plasma Wayland. Qt 6, C++ core, QML UI.
|
||
|
||
- Flick a key down for its secondary symbol; long-press for accented alternates
|
||
- iOS shift: tap = one letter, double-tap = caps lock, hold = shift while held
|
||
- Letters follow the system keyboard layout; the globe key switches it
|
||
- Auto-capitalization, double-space → ". " (both optional, ⚙ on the bottom bar), backspace repeat → word delete
|
||
- Long-press space = trackpad; slide from `.?123` onto a symbol and release
|
||
- Optional PC key blocks: function row, navigation (ins/home/pg up, del/end/pg dn, arrows), numeric keypad; any mix, typing keys included (⚙)
|
||
- Floating: drag the bottom bar, resize from the corner; geometry is remembered per screen
|
||
|
||
## Build & test
|
||
|
||
```sh
|
||
cmake -B build -G Ninja && cmake --build build
|
||
ctest --test-dir build
|
||
```
|
||
|
||
Needs Qt ≥ 6.8 (Quick, WaylandClient, DBus, Test), LayerShellQt, xkbcommon, wayland-protocols.
|
||
|
||
## Run
|
||
|
||
KWin only offers the input-method protocol to the process it launches itself.
|
||
|
||
| Where | How |
|
||
|---|---|
|
||
| Nested session (safe) | `kwin_wayland --no-lockscreen --socket sloposk-dev --width 1400 --height 900 --inputmethod $PWD/build/src/sloposk kwrite` |
|
||
| Desktop | `cmake --install build --prefix ~/.local`, then System Settings → Keyboard → Virtual Keyboard → **sloposk** |
|
||
| UI only | `build/src/sloposk` (stays visible, types nowhere) |
|
||
|
||
Show/hide, e.g. from a global shortcut: `qdbus org.sloposk.Keyboard /Keyboard org.sloposk.Keyboard.Toggle`
|
||
|
||
Dev hooks: `SLOPOSK_AUTOTYPE=text` commits on focus; `SLOPOSK_SCREENSHOT=file.png` saves the window and quits.
|
||
|
||
## Layouts
|
||
|
||
Letters come from the system keymap (what KWin sends to every client): its Q/A/Z rows become the three letter rows. Letters elsewhere, e.g. Slovak ľščťž on the number row, become long-press alternates. The globe key switches the system layout over `org.kde.keyboard`, so the physical keyboard follows.
|
||
|
||
Everything else is `layouts/template.json`; `~/.local/share/sloposk/template.json` replaces it.
|
||
|
||
```json
|
||
{"type": "letters", "row": 0, "flicks": ["1", "2", "3"]},
|
||
{"type": "backspace", "width": 1.5, "stretch": true}
|
||
```
|
||
|
||
- Key: a string, or an object with `type` (`char` `space` `backspace` `enter` `shift` `layer` `globe` `dismiss` `spacer` `letters` `keysym`), `label`, `shifted`, `flick`, `alternates`, `width` (key units), `target` (for `layer`), `stretch`
|
||
- `keysym`: sends the XKB keysym named by `keysym` (`Home`, `F5`, `Left`...) on press; `repeat` auto-repeats while held
|
||
- `letters`: the keymap row `row` (0–2), with `flicks` handed out left to right
|
||
- `stretch`: the key grows so its row is as wide as the layer's widest (letter counts vary by layout)
|
||
- Top-level `alternates`: long-press choices per letter, after the keymap's own
|
||
- Top-level `sections`: optional blocks, `{"id", "name", "placement": "above" | "right", "rows"}`; the user picks which show
|
||
|
||
## Settings
|
||
|
||
`~/.config/sloposk/sloposk.conf`, also editable from the ⚙ panel: `typing/autoCapitalize`, `typing/doubleSpacePeriod`, `layout/visibleSections` (`main` plus section ids).
|
||
|
||
## Architecture
|
||
|
||
```
|
||
qml/ view only
|
||
input/ touch → PointerTracker gestures → KeyboardController rules
|
||
engine/ key output → text ops (DirectEngine; prediction/swipe later)
|
||
backend/ text ops → compositor (KWin input-method-v1); the compositor's keymap
|
||
layout/ template JSON + keymap letters → Layout → LayoutModel (geometry, hit testing)
|
||
window/ floating layer-shell placement, visibility, saved geometry
|
||
app/ D-Bus control and system layouts, dev hooks
|
||
settings/ persisted user preferences
|
||
```
|
||
|
||
`sloposk_core` (everything compositor-independent, plus the `Sloposk` QML module) is a static library shared by the app and the tests.
