 This dataset collects **function-level information from ArkTS (HarmonyOS Ark TypeScript) projects**, including original functions, docstrings, abstract syntax tree (AST) representations, obfuscated versions, and source code metadata. It is suitable for tasks such as code analysis, code understanding, AST research, and code search.
 
+ArkTS is a core programming language in the OpenHarmony ecosystem. This dataset was constructed from open-source repositories crawled from GitHub and Gitee, targeting code retrieval and code evaluation tasks.
