Changelog

[0.0.2] - 2026-04-01​

Added​

• allowFontScaling option — automatically applies system font scale (PixelRatio.getFontScale()) to fontSize and lineHeight, matching React Native's <Text> behavior. Defaults to true.
• isFontAvailable(fontFamily) API — check if a custom font is registered on the device before measurement.
• Warning logs when a custom font is not found (iOS: RCTLogWarn, Android: Log.w). Previously fell back to system font silently.
• Obstacle Text Demo with real-time stats panel (FPS, reflow time, line count, measure count).
• Pretendard Regular/Bold font in example app with custom font comparison demo.

Fixed​

• iOS crash when measuring empty text — ctLines array was empty but accessed at index 0.
• React dual-instance error — deduplicated React across monorepo workspaces via resolutions.
• Metro module resolution — added react-native and source entry points to package.json.
• Frame-rate-dependent ball speed in ObstacleTextDemo — now uses delta time (120px/s).
• CI stability — eslint configs, turbo filters, docs workspace separation, Jest passWithNoTests.

Changed​

• README simplified with reference to original pretext.
