Release v0.12.0 · emprcl/runal

This one is all about stability 🩹

✨ Features

add a Scoop bucket for Windows: scoop bucket add emprcl https://github.com/emprcl/scoop-bucket then scoop install runal. Docs.
c.push() / c.pop() now use a stack, so nested save/restore of the drawing state works; an unbalanced push() is reported as a debug warning instead of silently leaking to the next frame. Docs.
c.loadImage() also accepts .jpeg files and uppercase extensions, and reports an explicit error on an unsupported format instead of drawing nothing. Docs.
⚠️ Deprecation Notice (Go package): runal.Start() now returns (*sync.WaitGroup, error) instead of *sync.WaitGroup. Handle the error when the terminal can't be initialized; runal.Run() is unchanged.

fix terminal being left in raw mode with a hidden cursor when a sketch exits, is interrupted, or loses stdin.
detect terminal resizes on Windows, which has no SIGWINCH; the canvas now follows the window there too.
fix runtime errors (missing font file, missing ffmpeg, failed export, unreadable terminal size) killing the whole process; they now stop rendering and print an error.
fix exported png, gif and mp4 files containing terminal cleanup escape sequences.
fix gif playback speed: frame delay is now computed correctly for any fps instead of rounding to zero above 100 fps.
fix c.loop() restarting at 30 fps instead of the fps set with c.fps(); fps values are now clamped to [1, 240].
fix crash on multi-byte characters: c.text(), c.stroke() and c.cellModeCustom() now handle unicode and empty strings.
fix c.image() drawing at the wrong size when width and height are omitted.
fix c.loopAngle(0) and c.saveCanvasToGIF() / c.saveCanvasToMP4() with a zero duration crashing.
fix JavaScript sketch reloading: saves are now debounced and atomic saves (editors that replace the file) are picked up, so a reload no longer misses changes or leaves the previous sketch running.
