ArkTS Function Dataset

Dataset Hub: hreyulog/arkts-code-docstring

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.

Dataset Structure

The dataset contains three splits:

train: Training set
validation: Validation set
test: Test set

Each split is a JSON Lines (.jsonl) file, where each line is a JSON object representing a single function.

Features / Columns

Field	Type	Description
`nwo`	string	Repository name
`sha`	string	Commit SHA
`path`	string	File path
`language`	string	Programming language
`identifier`	string	Function identifier / name
`docstring`	string	Function docstring
`function`	string	Original function source code
`ast_function`	string	AST representation of the function
`obf_function`	string	Obfuscated function source code
`url`	string	URL to the code in the repository
`function_sha`	string	Function-level SHA
`source`	string	Code source (GitHub / Gitee)

Usage

from datasets import load_dataset

# Load the dataset
dataset = load_dataset("USERNAME/DATASET_NAME")

# Inspect the first training example
print(dataset["train"][0])

# Check dataset features
print(dataset["train"].features)
