The kiosk lacks an input method framework, so SDL2 never generates TextInputEvent. The WiFi password page already had a keycodeToChar fallback but email and license key pages did not — characters were never appended to inputText. Also removes excessive debug logging from the previous commit. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
RhemaWave
A Go-based fullscreen SDL2/OpenGL application for Linux kiosk systems. Displays proclamations with audio playback and animated visual patterns.
Development
Development uses Nix for a reproducible build environment.
nix develop # enter dev shell
go build -o bin/rhemawave rhemawave.go # build
./bin/rhemawave # run
./dev_scripts/reset.sh # reset database (if needed)
Prerequisites
- Nix with flakes enabled
- A display server (X11/Wayland) and audio device for running the application
Architecture
- Page-based UI — SDL2/OpenGL 3.3 fullscreen rendering with a page stack for navigation
- Proclamation player — scrolling text display with synchronized audio playback
- Startup validation — WiFi, TOS acceptance, email, license key checks
- Singleton managers — ShaderManager, FontManager, Logger (initialized once via
sync.Once)
