What's New

Geisterhand: in-process input fuzzer for Perry UI

New --enable-geisterhand flag embeds an HTTP server (default port 7676) for programmatic widget interaction and automated UI testing. The perry-ui-geisterhand crate provides endpoints for clicking, typing, sliding, toggling, hovering, double-clicking, and taking screenshots across all 5 native platforms. Chaos mode randomizes interactions for fuzz testing. Configurable port via --geisterhand-port <PORT>.

  • Screenshot capture on all 5 native platforms (macOS CGWindowListCreateImage, iOS UIGraphicsImageRenderer, Android JNI, GTK4 GskRenderer, Windows PrintWindow+inline PNG encoder)
  • Auto-build: --enable-geisterhand automatically compiles required libs when missing
  • HTTP endpoints: /widgets, /click/:h, /type/:h, /slide/:h, /toggle/:h, /state/:h, /hover/:h, /doubleclick/:h, /screenshot, /chaos/start|stop|status

WASM target: full perry/ui support

The --target wasm output now supports the complete perry/ui widget set via DOM-based JS runtime. 170+ UI functions ported including widget creation, reactive State system, styling, events, canvas drawing, menus, toolbars, sheets, dialogs, keyboard shortcuts, navigation stacks, and windows. Firefox NaN canonicalization fixed via memory-based calling convention for all 150+ bridge functions.

Documentation

New pages for WebAssembly platform, perry-styling/theming, perry run command, --minify flag, gc() built-in, and Geisterhand testing guide (all 5 platforms documented).

Bug fixes

  • Detached method this-unbinding: CAPTURES_THIS_FLAG prevents incorrect this in detached method calls
  • Object literal method this-binding: via closure capture
  • Comparison operators: reverted to 1.0/0.0 (NaN-boxed booleans broke arithmetic)
  • String() coercion: now handles BigInt values
  • CLASS_CAPTURE: skips class-internal parameter LocalIds
  • Closure default params: simplified check to TAG_UNDEFINED only
  • Regex .test(): works on Named(RegExp) variables; inline Math.PI/E/LN2 constants
  • TsParamProp: TypeScript parameter properties now compile correctly
  • NaN-boxing fixes: proper tags for closure args, array method returns, LocalSet for closures in Any-typed locals, IndexSet string-key path, dynamic closure calls on object properties
  • Rest params in closures: args correctly packed into array
  • Nullish coalescing (??): no longer treats strings/pointers as nullish
  • Shared SHAPE_CACHE corruption: fixed key collision in object field init
  • Number() hex string parsing: now parses 0x prefixed strings correctly
  • Native library stubs: don't generate stubs for native library FFI functions
  • Mutable capture detection: walks into ArrayPush/ArrayUnshift/ArrayPushSpread
  • Class instance .map() interception: fixed; var loop closure hoisting; user-defined class type inference
  • Plugin builds: restore dead_strip with selective symbol retention
  • String-returning function calls: recognized in concat and console.log
  • Dynamic property access: via array key

New APIs

  • Uint8Array.prototype.set(source, offset) and Uint8Array.prototype.fill()
  • trimStart() / trimEnd() string methods
  • Plugin host support: export symbols for dlopen'd plugins
