Config Generation

Generate configuration files in various formats.

Quick Start

import json
import yaml  # pip install pyyaml

config = {
    "app": {"name": "myapp", "version": "1.0.0"},
    "settings": {"debug": False, "port": 8080}
}

# JSON
with open("config.json", "w") as f:
    json.dump(config, f, indent=2)

# YAML
with open("config.yaml", "w") as f:
    yaml.dump(config, f, default_flow_style=False)

Common Patterns

Generate .gitignore

def generate_gitignore(patterns: list[str]) -> str:
    return "\n".join(patterns) + "\n"

gitignore = generate_gitignore([
    "*.pyc",
    "__pycache__/",
    ".env",
    "venv/",
    "dist/",
    "*.egg-info/"
])

Generate pyproject.toml

import toml  # pip install toml

config = {
    "project": {
        "name": "myproject",
        "version": "0.1.0",
        "dependencies": ["requests>=2.28.0"]
    },
    "tool": {
        "pytest": {"testpaths": ["tests"]}
    }
}

with open("pyproject.toml", "w") as f:
    toml.dump(config, f)

INI config

import configparser

config = configparser.ConfigParser()
config["database"] = {"host": "localhost", "port": "5432"}
config["logging"] = {"level": "INFO"}

with open("config.ini", "w") as f:
    config.write(f)

Environment file

def generate_env(variables: dict) -> str:
    return "\n".join(f"{k}={v}" for k, v in variables.items())

env_content = generate_env({
    "DATABASE_URL": "postgresql://localhost/db",
    "SECRET_KEY": "your-secret-key",
    "DEBUG": "false"
})
