Add DS4 Color plugin (Hy4ri/ds4-color) (#52)
* feat: add PS4 Colors plugin (DS4 lightbar control) Wraps the ps4-colors CLI (github.com/Hy4ri/ps4-colors) as a Noctalia plugin: bar button + color panel (native picker, hex field, presets) that sets the DualShock 4 lightbar via the ps4-colors binary. NOTE: thumbnail.webp still pending (generated in noctalia thumbnail generator) — CI will flag the missing asset until added. * fix: add PS4 Colors thumbnail (solid crimson card) 960x540 WebP, deep crimson (#990000) to match the plugin accent. * feat: left-click applies saved color, panel adds Save button - widget: left-click applies the saved color via service; right-click opens panel - service: add 'save' IPC (persist without touching controller) - panel: Save (persist) + Apply (set now) buttons - translations: add 'save' key * refactor: implement DS4 protocol in pure Lua (drop C dependency) The plugin now writes the HID output report to /dev/hidrawN directly via noctalia.writeFile. USB report 0x05 (32B) and Bluetooth report 0x11 (78B) with CRC32 are built and the CRC verified against the kernel algorithm. Device detection scans /sys/class/hidraw uevent for Sony DS4 PIDs. No external binary or library required. * fix: panel renders black box (ipairs(nil) at script load) Move preset-click handler registration into onOpen (after presets are loaded) instead of module top-level, where ipairs(nil) threw and aborted the whole panel entry. Guard presets with 'or {}'. Replace unsupported width='100%' string with a numeric width on the swatch. * fix: match color_picker panel schema exactly (drop invented props) Remove border='primary' (unknown value -> whole tree abort) and wrap=true. Swatch now uses border='outline' + borderWidth to show selection, mirroring oldirtty/color_picker. Aligns every ui.* node with a known-good panel. * fix: service dead on load (pluginDataDir nil concat) + real device write - Resolve pluginDataDir lazily + nil-guard lastFile() so the service entry actually loads (top-level concat on nil threw -> no onIpc -> no apply -> no notification, which is why the color never changed). - setLightbar tries noctalia.writeFile, falls back to a python3 O_WRONLY binary write for the /dev/hidrawN char device (writeFile is file-oriented). * fix: replace Luau bitwise ops (&/|/~/>>) with math-only helpers Noctalia's Lua is strict (PUC-Rio semantic), not Luau: '&', '|', '~', '>>' are syntax errors -> service failed to load at crc32_init -> no apply. Added band/rshift/bxor/bnot32 math helpers; CRC32 + BT report now use them and still produce the verified CRC 523bce6f. * fix: panel black box (readonly _G) — use static onPreset1..9 globals Noctalia's _G is immutable at runtime, so assigning _G['onPreset'..i] in onOpen threw 'attempt to modify a readonly table' and aborted the panel. Presets are a fixed list, so define onPreset1..9 as plain module globals calling a shared applyPreset(i). Remove dead makePresetHandler. * fix: drop unsupported textAlign prop on ui.input (ui-tree warning) 'textAlign' is a label prop, not an input prop; Noctalia ignored it with a [WRN] ui-tree log line. Input defaults to left align anyway. * fix: use device-gamepad-2 icon for catalog + bar glyph 'controller' glyph was missing; swap to device-gamepad-2 for both the plugin catalog icon and the bar widget default glyph. * rename: PS4 Colors -> DS4 Color (id Hy4ri/ds4-color, dir ds4-color/) Rename plugin id, display name, bar glyph default, translation key (ps4_colors -> ds4_color) and all internal IPC references. Drop the stale ps4_colors_missing string (plugin has no external binary dependency). Keep accurate comments crediting the original ps4-colors C source. * ui: shorten panel (height 520->400, tighter gaps/padding, smaller swatch) Save/Apply buttons were already the last row (bottom of the column); this just compacts the overall panel height. * art: use panel screenshot as thumbnail (960x540 webp, crimson bg) * fix: lowercase author in id (CI validate: author must match ^[a-z0-9][a-z0-9._-]*$) 'Hy4ri' -> 'hy4ri' in id, author, and all internal IPC references. * fix: thumbnail * fix(review): declare python3 dependency + document hidraw fallback Reviewer flagged: plugin declared dependencies=[] but the hidraw write fallback invokes python3, so systems without Python cannot apply the color if the direct writeFile fails. Declare 'python3' in dependencies, note it in the manifest description, and document the requirement in README Requirements. * security(review): validate color as 6-hex at every trust boundary Reviewer flagged: last.json value entered shared state unvalidated, then got single-quote-interpolated into /bin/sh -c via runAsync -> shell injection. - Add isHex6() (exactly ^[0-9a-fA-F]{6}$) and enforce it at: loadLast (poisoned last.json), onSubmitHex, onApply/onSave (from state), onIpc apply/save, and the apply()/save() service funcs. - Since only 6 hex chars can reach runAsync, the single-quote interpolation is provably safe (no quote-breaker / metachar can survive). - Also fixes a latent bug: the old %x regex captured only 5 hex, rejecting valid 6-char colors like 990000. * Update plugin description for clarity Removed mention of 'hidraw write fallback' from the description. --------- Co-authored-by: M57 <hy4ri@users.noreply.github.com> Co-authored-by: Lemmy <studio@quadbyte.net>

# DS4 Color
|
||||
|
||||
Set the LED lightbar colour on a connected PlayStation 4 DualShock 4 controller
|
||||
from a Noctalia bar button and a color panel. Click the bar icon to apply your
|
||||
saved colour, or right-click to open the panel and pick a new one.
|
||||
|
||||
The entire DualShock 4 output-report protocol (USB report `0x05`, Bluetooth
|
||||
report `0x11` with CRC32) is implemented in **pure Lua** — no external binary or
|
||||
library is required. The plugin writes the HID output report straight to
|
||||
`/dev/hidrawN`.
|
||||
|
||||
## Plugin
|
||||
|
||||
| Field | Value |
|
||||
| --- | --- |
|
||||
| ID | `hy4ri/ds4-color` |
|
||||
| Entries | Bar widget: `widget`; panel: `panel`; service: `service` |
|
||||
|
||||
## Requirements
|
||||
|
||||
Requires `python3` (declared in `dependencies`): if Noctalia's `writeFile` cannot
|
||||
open the `/dev/hidrawN` node `O_WRONLY`, the plugin falls back to a `python3`
|
||||
one-liner that performs the raw binary write. Systems without Python present cannot
|
||||
apply the colour when the direct write path fails. The plugin also needs
|
||||
read/write access to the DualShock 4 `/dev/hidrawN` node.
|
||||
|
||||
On most modern Linux desktops with `systemd-logind` and `uaccess`, the device
|
||||
node is automatically accessible when you are logged in at the seat.
|
||||
|
||||
On headless systems or systems without `uaccess`, create a udev rule:
|
||||
|
||||
```udev
|
||||
SUBSYSTEM=="hidraw", ATTRS{idVendor}=="054c", ATTRS{idProduct}=="05c4|09cc|0ba0", MODE="0660", GROUP="plugdev"
|
||||
```
|
||||
|
||||
Then add your user to the `plugdev` group:
|
||||
|
||||
```sh
|
||||
sudo usermod -a -G plugdev $USER
|
||||
```
|
||||
|
||||
Re-login or run `udevadm trigger` for the change to take effect.
|
||||
|
||||
## Usage
|
||||
|
||||
**Left-click** the **DS4 Color** bar button to instantly apply the last saved
|
||||
colour to every connected DualShock 4. **Right-click** the bar button (or run the
|
||||
command below) to open the panel:
|
||||
|
||||
```sh
|
||||
noctalia msg panel-toggle hy4ri/ds4-color:panel
|
||||
```
|
||||
|
||||
In the panel: pick a colour with the native picker, type a hex value
|
||||
(`RRGGBB` / `#RRGGBB` / `0xRRGGBB`), or tap a preset. **Save** persists the
|
||||
chosen colour (so left-click reapplies it later) without touching the
|
||||
controller; **Apply** sets the lightbar immediately and also saves it. The saved
|
||||
colour survives restarts.
|
||||
|
||||
## Settings
|
||||
|
||||
| Setting | Type | Default | Description |
|
||||
| --- | --- | --- | --- |
|
||||
| `glyph` | `glyph` | `device-gamepad-2` | Icon shown on the bar button. |
|
||||
|
||||
## IPC
|
||||
|
||||
```sh
|
||||
noctalia msg plugin hy4ri/ds4-color:service all apply <hex>
|
||||
noctalia msg plugin hy4ri/ds4-color:service all save <hex>
|
||||
```
|
||||
|
||||
## Notes
|
||||
|
||||
- Implements the DualShock 4 HID output report protocol directly in Lua
|
||||
(derived from the Linux kernel `drivers/hid/hid-playstation.c`): USB report
|
||||
id `0x05` (32 bytes) and Bluetooth report id `0x11` (78 bytes) with the
|
||||
required CRC32 checksum. No kernel drivers or external binaries.
|
||||
- Detects all connected DS4 controllers (USB `0x03` and Bluetooth `0x05` bus)
|
||||
by scanning `/sys/class/hidraw/*/device/uevent` for Sony VID `054c` and
|
||||
product IDs `05c4` / `09cc` / `0ba0`.
|
||||
- The last chosen colour is persisted to the plugin data directory
|
||||
(`last.json`) and restored on next open. Left-clicking the bar button applies
|
||||
the saved colour; the panel's **Save** button updates it without writing to
|
||||
the controller.
|
||||
- No network access. Only the locally detected DualShock 4 controllers are
|
||||
touched.
