find.keyboardPopup() (finders.js VERSION 3) replaces the same
g_PopupManager lookup in the swipe, extra keys and touch typing patches
(VERSIONs 29, 24, 4). hub.js keeps its own: it gets no finder library.
textmodel's lastReset (the patch logs the reason itself), __sfuiSwipe.model,
corrector's distance/fold and the decoder's N/W/cost/resample exports were
read by nothing (patch, tests, replay script).
Its 0.5 s poll (a SharedJSContext timer) kept running until the next
injection and could publish a hidden strip with its own sequence numbers
over the new popup's, so a pick on the panel was dropped as stale. The
poll now detaches it once the popup's document is gone.
- gesture-input.js: drop the unused mode getter and release().
- relay.mjs: both sides have a binding; no condition.
- hub.js: the frame cadence is documented once (bridge-patch.js); errors
listed.
- docs: the bridge's idle cost and "one word at a time" stated once;
twoHanded's README row points to the docs; rewrapped lines.
keyboard.vr.functionKeys.enable (default off): while AltGr (Fn on layouts
without AltGr) is one-shot, locked or held, the strip shows F1-F12 instead
of the suggestions. A tap types the extra key VKX_F<n>, which the extra
keys' patch presses with xdotool together with the active Ctrl/Alt/Shift
(Alt+F4, Ctrl+F5) and releases the toggles; the text model resets, like
for Esc. The suggestions are kept as they are meanwhile, so when AltGr goes
off the strip shows the same items and selection again.
- vr-keyboard/function-keys.js: what the strip shows, the F-key keys.
- patch.js (VERSION 27): the strip's view, F-key picks, AltGr changes via
a componentDidUpdate on the keyboard instance (and the poll).
- Allowlist: F1-F12 with any modifiers; Enter still refused.
- relay.mjs: up to 12 strip items.
- Assertions: needs keyboard.vr.enable, extraKeys.enable and a strip
position "above"/"below" ("inside" would hide the AltGr number row).
- Tests: function-keys.test.mjs (switching and restoring, keys against
the allowlist, text model), allowlist F-key cases.
With both lasers on the keyboard SteamVR forwards per poll only one laser's
movement, so the pressing one may get no touchmoves and its swipe became a
tap. keyboard.vr.swipe.twoHanded (default on; turns on the controller
bridge): a press is attributed to the hand whose laser hit is nearest to it
(within 30 px, the trigger as a tiebreak; without recent frames the first
frame after the press decides, within 60 px). The path comes from runs of
one source: the touch's own moves while they flow, that hand's laser hit
per bridge frame once they pause for 60 ms, touchmoves again if frames
pause. A touchend disagreeing with the laser during a bridge run ends at
the laser. Touchmoves on the other hand's laser move the attribution.
Without fresh frames: touch events only, as before. A second press during
a swipe stays Steam's tap (one text field, one word at a time).
The bridge sends full rate only on demand now: hub.js demand(ms) goes
back through the relay (CDP binding __sfuiCtlIn) to systemui's
__sfuiCtl.demand; the swipe patch asks from the press to the release.
Tests: gesture-input with the two-controller recording and synthetic bridge
frames (a pressing hand without touchmoves, attribution with both lasers on
the keyboard, a stale bridge, frames stopping mid-swipe, re-attribution,
interleaved hover and presses); hub demand.
With both controllers on the keyboard, the idle one's hover (mouse events,
pointerId 1) arrived during the other's press and went into the swipe path
("tust" for "test"). A gesture now belongs to the contact that started it
(touch identifier, pointerId or mouse; gesture-input.js): other contacts'
moves, releases and cancels are ignored, a second press meanwhile stays
Steam's tap. Test with a recorded two-controller swipe.
Steam sends Tab as the text "\t" and drops Shift. With Shift, Tab now
goes to the xdotool helper (shift+Tab, ISO_Left_Tab on any keymap); the
suggestions text model resets on it like on Shift+arrows. The helper's
allowlist moves to allowlist.mjs with a test (flake check
vr-keyboard-extra-keys).
Opt-in with steamFrame.keyboard.vr.enable; swipe, autocorrect and
completion suggestions, Backspace drag and haptics are on under it.
- vr-keyboard/patch.js (Steam UI): swipe decoder, a model of what the
keyboard typed, suggestions that only replace what they typed, Backspace
drag with word detents and retyping; checks its Steam internals by
signature (signatures.json: vr-keyboard) and stays stock otherwise.
- vr-keyboard/panel.js (SteamVR systemui) + relay.mjs (user service
vr-keyboard-relay): the suggestion strip as a dashboard panel below or
above the keyboard (signatures: vr-keyboard-panel).
- Dictionary built from nixpkgs' wordfreq and hunspellDicts; default: the
keyboard.layout language (de, fr, es, it, nl, pt, sv) plus English.
- Tests: keyboard.vr.checks and the flake check vr-keyboard.
