cl.ArkCompiler.1 Addition of ArkTS Syntax Validation

Added ArkTS syntax validation to the compilation process. Syntax issues are classified as warning or error, depending on the mode specified by compatibleSdkVersion, which are generally configured in the build-profile.json5 file.

For details, see TypeScript to ArkTS Cookbook.

• In compatible mode, where the value of compatibleSdkVersion is smaller than 10, syntax issues are reported as warnings and will not block the compilation process.
• In compatible mode, where the value of compatibleSdkVersion is greater than or equal to 10, syntax issues are reported as errors and will block the compilation process.

Change Impact

• In OpenHarmony SDK 4.0.10.3 and later versions, syntax validation is enabled. During project compilation, a warning is generated for code that does not comply with the ArkTS syntax rules. These warnings will not block the compilation process. Yet, you are advised to adapt the code based on the warnings.
• In the release edition of API version 10, the OpenHarmony SDK is expected to report an error for an ArkTS syntax issue. In this case, the compilation process can continue only after the issue has been rectified.
