%description
A Rust port of Hydra — the live-codable video synthesizer created by Olivia Jack. Takes Rhai scripts,
compiles them to GLSL shaders, and renders them via OpenGL. The core is a library with zero GUI
dependencies, suitable for embedding. A standalone binary is included for testing and standalone use.
Originally extracted from Sova, the polyglot live coding sequencer.
Some shortcuts:
- Ctrl/Cmd + Enter         Evaluate the current sketch
- Ctrl/Cmd + S             Save the current sketch to a .hydra file
- Ctrl/Cmd + O             Open a .hydra file
- Ctrl/Cmd + Shift + H     Toggle editor visibility (hide the code overlay, keep the visuals running)
- Tab                      Toggle the options sidebar — tempo/font/text-opacity, camera status, and the scene-bank grid (see below)
- Alt + 0-9 / A-F          Recall slot 0-F (hex) in the active bank — loads and immediately evaluates its saved code
- Alt + Shift + 0-9 / A-F  Save the editor's current code into that slot
- Alt + -> / <-            Cycle to the previous/next scene bank
- Alt + X                  Export the active bank (16 slots) as a .bhr file
- Alt + I                  Import a .bhr file into the active bank, replacing its 16 slots
