Decker v1.4 contains several enhancements to audio playback features as well as bugfixes.

New Features

• Pressing space or enter with one widget selected will open its properties panel, as another alternative to double-clicking or "Widgets -> Properties..."
• The "sys.playing" attribute indicates whether sound clips are currently playing, offering a non-blocking alternative to sleep["play"].
• Cards now emit a "loop" event which can be used to programmatically schedule complex background audio sequences. There is a new example deck which explains playing sounds, including how to use this feature:

Fixes (Native)

• Fixed crashes caused by trying to loop an invalid/missing sound clip.
• Fixed crashes caused by applying the "mag" operator to atoms in Lil.
• Expanded the range of valid operands to the modulus (%) operator in Lil.

Fixes (Web and Native)

• Overwriting a deck in "Protect" mode did not write the deck out with the "locked" attribute.
• Loading a deck or leaving interact mode now clears the background audio loop, if any.
• Exporting an image with a pending rectangular selection now commits it before performing the export.
• Corrected inconsistencies between how large numbers were formatted in Web and Native Lil implementations.
