OneDrop GUI - Graphical user interface for MilkDrop visualizations

Modules§

keymap 🔒: Keyboard → action mapping for the OneDrop GUI.
options_ui 🔒: egui-based Options overlay rendered on top of the MilkDrop visuals.
settings 🔒: Persistent user settings for the OneDrop GUI.

App 🔒
Args 🔒: Command-line arguments for onedrop-gui.
Blit 🔒: Fullscreen-triangle blit that samples the engine’s final display texture and writes to the swapchain. Sampling (rather than copy_texture_to_texture) sidesteps two failure modes: it doesn’t need COPY_DST on the swapchain (not guaranteed on all platforms), and sRGB conversion happens automatically when source and destination formats disagree.

apply_options_actions 🔒: Apply one frame’s worth of Options-panel changes to the live engine. Each field of OptionsActions is Some only when the user just moved that widget, so the function is a series of cheap no-ops on quiet frames.
beat_mode_from_name 🔒: Parse a beat-detection mode name (matches the Options-panel dropdown and the engine’s BeatDetectionMode::name()). Unknown values map to Off, which is also the engine’s boot default.
discover_presets 🔒: Discover preset files. Honours --preset first, then --preset-dir (one or more), then the default search path. Returns the list of .milk files found, in lexicographic order so the boot sequence is reproducible.
main 🔒
relaunch_self 🔒: Spawn a fresh copy of the current binary with the same CLI args and exit. Used by the Options panel’s “Apply & restart” button so settings that can’t be applied live (MSAA, texture format) take effect on the next boot. We rely on the caller having just called Settings::save() so the new process reads the user’s edits.
