Dataset Structure

Data Fields

Field	Type	Description
code	string	Content of the source file (UTF-8 encoded)
repo_name	string	Name of the GitGud repository (format: username/repo)
path	string	Path of the file within the repository (relative to repo root)
language	string	Programming language detected by file extension mapping
license	string	License of the repository (SPDX identifier or "unknown")
size	int64	Size of the source file in bytes

Data Format

• Format: Apache Parquet with Zstd compression (level 19)
• File Structure: 17 files (gitgud-00000.parquet to gitgud-00016.parquet)
• Rows per shard: ~1,000,000 (except last shard: 322,315)

Data Splits

All examples are in the train split. There is no validation or test split.

Example Data Point

    'license': 'mit',
    'size': 2048
}

Dataset Creation

Pipeline Overview

The dataset was created through a multi-stage pipeline:

1. Repository Discovery: Scraping public repository URLs from GitGud.io's GitLab API v4 endpoint using multiple sort orderings (id, name, path, updated_at, star_count, last_activity_at, similarity)
2. Branch Enumeration: Fetching all branches for each repository via the GitLab API
3. Archive Download: Downloading .tar.gz archives for each repository/branch combination
4. Content Extraction: Extracting and filtering source code files from archives
5. Parquet Generation: Writing filtered records to Parquet shards with Zstd compression

Language Detection

Programming languages are detected using file extension mapping. The pipeline maps ~80 programming languages by their file extensions, including:

• Major languages: Python, JavaScript, TypeScript, C, C++, C#, Java, Go, Rust, Ruby, PHP
• Configuration: JSON, YAML, TOML, XML, INI
• Markup: HTML, CSS, Markdown, LaTeX
• Game development: GLSL, HLSL, GDScript
• And many more

Files with unrecognized extensions are labeled with the extension itself (without the dot prefix). Files without extensions are labeled as "none" or by special filename matching (e.g., "Dockerfile", "Makefile").

License Detection

Licenses are detected by:

1. Scanning for license files (LICENSE, LICENSE.txt, LICENSE.md, COPYING, COPYING.txt, COPYING.md)
2. Matching license text against known patterns (MIT, Apache 2.0, GPL variants, BSD, Creative Commons, MPL, ISC, Unlicense, Artistic, WTFPL, Zlib, etc.)
3. Defaulting to "unknown" if no license can be detected

File Filtering

Filtering is applied to ensure data quality:

Size Limits

Limit	Value
Max repository archive size	64 MB
Max line length	1,000 characters

Content Filtering

• Binary Detection: Files with null bytes in the first 1KB are excluded
• UTF-8 Validation: Files must be decodable as UTF-8 (with fallback to latin-1, cp1252, iso-8859-1)
• Long Lines: Files with any line exceeding 1,000 characters are excluded
• License Files: License files (LICENSE, COPYING, etc.) are excluded from the dataset (but used for license detection)

Source Data

All data originates from public repositories hosted on GitGud.io.

Considerations for Using the Data

Personal and Sensitive Information

The dataset may contain:

• Email addresses in code comments or configuration files
• API keys or credentials that were accidentally committed
• Personal information in comments or documentation

Users should exercise caution and implement appropriate filtering when using this data.

Licensing Information

This dataset is a collection of source code from repositories with various licenses. Any use of all or part of the code gathered in this dataset must abide by the terms of the original licenses, including attribution clauses when relevant. The license field in each data point indicates the license of the source repository.
