IOCCC Winners Database

This repository contains a database of all the winners in the International Obfuscated C Code Contest (IOCCC). The database includes information about each winner, including their source code, spoiler, hint (if available), and the year of their participation.

The information in this database was gathered from the official IOCCC repository available at https://github.com/ioccc-src/winner. We are grateful to the IOCCC community for providing this valuable collection of obfuscated C code entries.

Introduction

The International Obfuscated C Code Contest is a renowned competition that celebrates the art of writing creative, puzzling, and obfuscated C code. This database aims to provide a comprehensive collection of IOCCC winners, making it easier for enthusiasts and researchers to explore and analyze the contest's historical entries.

How to Access the Database

The IOCCC Winners Database is available in SQLite format, allowing for easy integration with various applications and programming languages. To access the database, follow these steps:

1. Clone the repository to your local machine:

   git clone https://github.com/nir-mo/ioccc-db.git
   

2. Navigate to the repository directory:

   cd ioccc-db
   

3. The SQLite database file is located at ioccc_winners.sqlite. You can use your preferred SQLite client or library to connect to the database and perform queries.

import pandas as pd
import sqlite3

# Connect to the SQLite database
conn = sqlite3.connect('ioccc_winners.sqlite')

# Query to select 10 rows of data from the "winners" table
query = "SELECT * FROM winners WHERE year < 1998 LIMIT 10"

# Read the table into a pandas DataFrame
df = pd.read_sql_query(query, conn)

conn.close()

How to Generate the Database

To generate the IOCCC Winners Database, follow these steps:

1. Install the required dependencies:

   pip install -r requirements.txt
   

2. Fetch the submodule from the IOCCC winners repository:

   git submodule update --init
   

   OR, If you encounter any issues with the submodule, you can clone the IOCCC winners repository manually into the winners directory:

   git clone https://github.com/ioccc-src/winner winners
   

3. Run the ioccc_db/cli.py script, specifying the directory containing the IOCCC winner entries:

   python ioccc_db/cli.py --verbose --force --output_file=../ioccc_winners.sqlite --ioccc_winners_directory=ioccc/winners.directory
   

4. The script will generate the ioccc_winners.sqlite file, which contains the SQLite database with all the winners information.

Technical Debts

The following are the known technical debts and areas for improvement in this repository:

• Add unit tests to ensure the correctness of the database generation process.
• Add support for hints with the encoding of Latin-1 to handle special characters and non-ASCII characters in the hint field.
