# High-Quality-Code: Synthetic + Real (MAXIMUM CODE)

A **massive, high-quality code dataset** built with **maximum code philosophy** – as much code as possible.

## Components

1. **Synthetic syntax-correction dataset** – 5M+ examples across 33 languages (original `code_syntax_dataset_1GB.csv`)
2. **Real high-quality code from GitHub** – 500 top-starred repositories – **BOTH zips and extracted source**

## Current Status: IN PROGRESS

- **Target**: 500 repos
- **Currently uploaded**: 12 extracted repos in `github_code/` + 6 zips in `github_code_zips/`
- **Upload method**: Direct commit to main, zip version (main→master fallback), no size limit, temp files deleted after upload
- **Process**: Running in background – final-max-code-uploader

This README will be updated again when 500 is reached.

## Structure (Maximum Code)

```
.
├── code_syntax_dataset_1GB.csv  # Synthetic: wrong_code, correct_code, explanation, language
├── github_code/                 # Real: Extracted source – MAX CODE
│   ├── owner__repo/
│   └── ...
├── github_code_zips/            # Real: Original zips – MAX PRESERVATION
│   ├── owner__repo.zip
│   └── ...
└── README.md
```

- `github_code/` – extracted source code for training (all files, no filtering)
- `github_code_zips/` – original zip archives for reproducibility

Both are uploaded for **maximum code**.

## Top 500 Source

Fetched via GitHub API: `stars:>5000 sort:stars desc` – 500 most-starred repos.

## How It Was Built (Maximum Code Philosophy)

```python
# For each repo in top 500:
# 1. Try main.zip, then master.zip, plus codeload URLs
# 2. NO SIZE LIMIT – even torvalds/linux, freeCodeCamp, etc.
# 3. Upload zip to github_code_zips/owner__repo.zip (direct commit)
# 4. Extract zip, upload folder to github_code/owner__repo/ (direct commit)
# 5. Delete local temp immediately – nothing kept locally
# 6. Repeat until 500
```

## Use Cases

- Pre-training LLMs on massive real code
- Fine-tuning for code correction (synthetic)
- Code generation, completion, understanding
- Maximum code = maximum learning

## Licenses

- Synthetic CSV: ODA-TL v1.0
- Real GitHub code: Respective original licenses (check each repo's LICENSE)
- Use responsibly.

## Links

- Dataset: https://huggingface.co/datasets/Corpus-NZ/High-Quality-Code
- In progress – final README will have full stats at 500 repos.

*Built by Corpus-NZ – maximum code, direct commits, no local storage.*
