Replaced hardcoded US scancode→escape-sequence table in fbcond's
text.rs with a configurable Keymap struct supporting TOML-based
keyboard layouts. Five layouts embedded at compile time:
- us.toml — US English (QWERTY), default
- ru.toml — Russian JCUKEN, #1 non-English locale throughout Red Bear OS
- uk.toml — UK English (QWERTY)
- de.toml — German (QWERTZ)
- fr.toml — French (AZERTY)
Implementation:
- src/keymap.rs: Keymap struct with TOML deserialization, scancode→byte
sequence lookup, embedded defaults via include_str!(). 6 unit tests.
- src/text.rs: TextScreen gains field. Hardcoded 12-arm
scancode match replaced with call. Same Ctrl+letter
translation fallback preserved.
- keymaps/*.toml: Five embedded layout files.
- Cargo.toml: added toml.workspace dependency.
- main.rs: registered mod keymap.
Keymap priority policy: English (US) default, Russian #1 non-English,
then UK/DE/FR. Unknown names fall back to US.
fbcond can start before vesad has registered the display, leaving
TextScreen.display.map as None. The old write() silently dropped all
output in that state, so getty/login prompts written during the race
window never appeared.
- Add pending_writes buffer to TextScreen.
- Buffer writes when display.map is None and log a warning.
- Flush buffered writes after a successful display handoff.
- Upgrade handoff success logs from debug to info so they appear in
the default boot log.
