From 1d85ef59b1e219c0729a620c2a786f75e211f75f Mon Sep 17 00:00:00 2001 From: Veronica Pril Date: Sun, 19 Oct 2025 20:33:17 -0700 Subject: [PATCH 1/5] feat: add xcode-xcstrings-v2 bucket with ICU MessageFormat support MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add opt-in xcode-xcstrings-v2 bucket type that converts CLDR plural forms to ICU MessageFormat for better translation quality and variable handling. ## Key Features - **ICU MessageFormat conversion**: Converts xcstrings plural forms to ICU format with metadata preservation - **Backward compatible**: Original xcode-xcstrings (v1) completely unchanged - **Opt-in migration**: Users explicitly choose v2 in their config - **Format preservation**: Maintains Objective-C format specifiers (%d, %.1f, %lld, %@) - **Variable handling**: Supports multiple variables with proper metadata - **CLDR support**: Handles all plural categories (zero, one, two, few, many, other) ## Implementation ### New Files - xcode-xcstrings-icu.ts - Core ICU conversion utilities (567 lines) - xcode-xcstrings-v2-loader.ts - V2 bucket loader (79 lines) - xcode-xcstrings-icu.spec.ts - 23 ICU conversion tests - xcode-xcstrings-lock-compatibility.spec.ts - 5 lock format tests - icu-safety.spec.ts - 22 safety tests for other bucket types ### Modified Files - loaders/index.ts - Register xcode-xcstrings-v2 bucket type - loaders/flat.ts - Add shouldPreserveObject option for ICU objects - loaders/variable/index.ts - ICU-aware metadata stripping - spec/formats.ts - Register xcode-xcstrings-v2 format ### Demo - demo/xcode-xcstrings-v2/ - Example files with ICU pluralization ## Lock File Format V1 (flattened): ``` item_count/one: item_count/other: ``` V2 (ICU object): ``` item_count: ``` ## Test Coverage - 72 total tests (50 new + 22 existing) - All 430 tests passing - Safety verified against 25+ bucket types 🤖 Generated with [Claude
