This example demonstrates implicit CALayer animation on macOS, where a red sublayer moves from one position to another when its `position` property changes. The code uses AppKit’s `NSPanel` and `NSView` with `wantsLayer` enabled, alongside Core Animation’s `CALayer` and `CATransaction` to animate the layer’s position over one second. The layer’s bounds and blue border are set explicitly, while the sublayer’s movement is triggered via a `setTimeout` callback, showing how implicit animations work for layer properties.

Testing how to animate a NSBox on the screen.

This example demonstrates how to animate a red NSBox across a macOS window using AppKit’s animation proxy. The code creates a floating NSPanel, configures it with a custom style mask, and disables the minimize and zoom buttons. An NSBox is added as a subview to the panel’s flipped content view, then its frame origin is moved via the `animator()` proxy to trigger a smooth animation. The implementation relies on `NSThread.mainThread().threadDictionary` to manage the panel’s lifecycle for repeat executions.

Animating the background blur of a NSView that is layer backed

This example demonstrates a layer-backed NSView that fades in with a Gaussian background blur over a fixed image, then reverses the effect. The animation cycles through a state where the view’s background transitions from fully transparent to a blurred, semi-transparent black overlay, using CABasicAnimation and CAAnimationGroup to coordinate opacity and blur radius changes. The code leverages the Objective-C libraries (NSView, CALayer, CIFilter) and the inherent layer-backing system to apply the blur filter via `CIGaussianBlur`, with timing controlled by `CAMediaTimingFunction`. The data source is a local PNG image file, and the animation runs on a timer, hiding the view after the fade-out completes.

Gist 611b52546f9a7b7b6c57

This example demonstrates UIKit physics-based animation on iOS, where a small red square falls under simulated gravity within a 300-by-100-point view. It shows how a UIView child is added to a parent container, given a red background color, and then subjected to a UIGravityBehavior from the UIDynamicAnimator class. The code initializes the animator with the parent view as its reference view, then attaches the gravity behavior to the subview, causing it to accelerate downward. The rendering stays within the standard UIKit view hierarchy, with no external data sources involved.

Trying to get NSPanel to expand downward.

A JavaScript sketch demonstrates an attempt to animate an NSPanel downward using the Sketch plugin API. The code creates a floating panel with a title bar and close button, initially sized at 312 by 210 pixels. After displaying the panel, it calls `setFrame_display_animate` to enlarge its height by 50 pixels. However, because the panel's origin remains unchanged, the animation expands the panel upward instead of downward. The commented-out alternative adjusts the y-origin by negative 50 pixels, which would shift the panel up to achieve the desired downward expansion. The sketch relies on `NSThread.mainThread().threadDictionary` for panel management and `NSMakeRect` for frame geometry.

Progressbar modal

This example demonstrates a modal progress bar displayed over the main application window, using a native macOS sheet to block interaction while a short task runs. The code creates an `NSProgressIndicator` with a blue tint, embeds it in an `NSWindow` configured as a document-modal sheet, and attaches it via `beginSheet_completionHandler` on `NSApplication.sharedApplication().mainWindow()`. The progress animation starts immediately, and the sheet closes after a three-second delay using `setTimeout` and `endSheet`, illustrating Apple’s AppKit APIs in JavaScript via JSTalk-style syntax.

Cocoa

This example shows a custom slider control built with Cocoa’s AppKit framework, using an `NSView` subclass to render a gradient-filled, rounded rectangular track. The view applies a linear gradient via `NSGradient` and sets a corner radius using layer-backed properties (`wantsLayer`, `layer.cornerRadius`). The code also attempts to load an image from a file named `knob.png` for the slider’s thumb, though the actual drawing of that image is commented out. The gradient and angle properties are exposed, with setters that trigger redraws via `setNeedsDisplay:`. The data source is the referenced image file, while the rendering relies on `drawRect:` and `drawInRect:angle:`.

Add padding to artboard (WIP)

This plugin demonstrates how to adjust an artboard's dimensions and reposition its contents with a user-defined padding value. It uses the Sketch JavaScript API, including `doc.selectedLayers`, `Rectangle`, and `UI.getInputFromUser`, to prompt for input and modify layer frames. The script shifts the artboard’s frame outward by the padding amount while moving all nested layers inward by the same value, preserving their relative positions. It relies on `selection.frame` and `layer.frame` properties to apply geometric transformations.

Creating a Sketch NSPanel

This example demonstrates how to create a custom, frameless floating panel with a vibrant, translucent background using the Sketch JavaScript API. The script creates an `NSPanel` with a titled, closable, and resizable window, and applies a `NSVisualEffectView` with a vibrant light appearance to achieve a frosted-glass effect. It uses `NSLayoutConstraint` objects to anchor the visual effect to the panel’s content view. The panel’s close button is handled via `setCOSJSTargetFunction`, which cleans up the panel reference and stops the script’s keep-alive loop.
