DevEco Studio Beta1 (6.0.0.418) New and Enhanced Features

• DevEco Studio supports developing API 20 projects.
• DevEco Studio adapts to the IntelliJ 2024.3.3 base upgrade, providing a new user interface with a simpler appearance and development experience.
• New page generation function supports multi-turn dialogue through natural language to generate usable page code for applications/meta-services, completing page construction quickly.
• Provides problem repair capabilities for syntax errors in compilation and build scenarios.
• New support for natural language interaction to analyze and explain performance issues in the current instance or project, helping developers quickly locate specific causes affecting performance.
• Supports querying changes in C APIs and provides cross-version query capabilities.
• Code Linter adds 3 new inspection rules, and the @typescript-eslint/explicit-function-return-type rule adds a configuration option to support inspection of .ets files.
• Enhanced Profiler tuning tool capabilities:
  • Snapshot analysis template supports displaying reference chains in chart form.
  • Snapshot analysis supports parsing the names of application object classes.
  • Launch template supports displaying ETS file loading during application cold start.
  • The Profiler tool's Energy template supports displaying abnormal energy consumption data and locating abnormal energy consumption components.
• Provides Graphics Profiler tools to capture GPU frame information.
• New support for quickly applying for partial ACL permissions via auto-signing.
• ohpm supports introducing dependencies using @module to point to module directories by module name.
• ohpm supports encrypted storage and reading of sensitive configuration items.
• ohpm command-line tools support the list --recursive option to display dependency trees of all modules.
• ohpm-repo supports OHMUrl version consistency verification for third-party library bytecode files.
• The hvigor-config.json5 file's execution section adds the optimizationStrategy field to specify the build mode. Command-line parameters support --optimization-strategy=performance/memory.
• The following fields are added under properties in the hvigor-config.json5 file:
  • ohos.rollupCache.usePathPlaceholder: Specifies whether to replace absolute paths in rollup caches under the build directory with placeholders.
  • ohos.rollupCache.useSourceHash: Specifies whether to replace source code in rollup caches under the build directory with corresponding hash content to reduce cache size.
