# Cookiecutter: Python Project Template Tool

Cookiecutter is a cross-platform command-line utility that creates projects from templates. It generates project structures by copying template directories and replacing templated variables with user-provided values, supporting any programming language or markup format.

## Core Functionality

### Template Processing

* Copies source directory trees and replaces names surrounded by templating tags `{{ }}` with values from `cookiecutter.json`
* Supports variable replacement in file names, directory names, and file contents
* Uses Jinja2 templating engine for advanced variable processing
* Handles multiple data types including strings, lists, booleans, and dictionaries

### Interactive Configuration

* Command-line prompts for template variables
* Default values specified in `cookiecutter.json`
* User can accept defaults or provide custom values during project generation
* Support for conditional prompts and validation

## Additional Features

### Hooks System

* Pre-generation hooks for input validation and setup tasks
* Post-generation hooks for environment initialization, dependency installation, and git repository setup
* Access to template variables within hook scripts

### Advanced Templating

* Private variables for computed values
* Choice variables for predefined options
* Template inheritance for shared configurations
* Custom Jinja2 extensions and filters

## Installation and Usage

### Installation

Install Cookiecutter as a global CLI tool with [uv](https://pydevtools.com/handbook/reference/uv.md):

```bash
uv tool install cookiecutter
```

To run Cookiecutter once without a permanent install, use [uvx](https://pydevtools.com/handbook/reference/uvx.md) (or [pipx](https://pydevtools.com/handbook/reference/pipx.md) on systems without uv):

```bash
uvx cookiecutter https://github.com/user/template
```

### Basic Usage

```bash
# Generate from local template
cookiecutter path/to/template

# Generate from Git repository
cookiecutter https://github.com/user/template

# Generate with specific branch/tag
cookiecutter https://github.com/user/template --checkout v1.0
```

## Pros

* Language agnostic template system
* Cross-platform support for Windows, Mac, and Linux
* No Python knowledge required for template usage
* Extensive community template ecosystem
* Flexible hook system for complex workflows
* Active maintenance and development

## Cons

* Requires Python runtime for execution
* Limited interactive CLI features compared to modern generators
* Template creation requires understanding of Jinja2 syntax
* No built-in template discovery or marketplace
* Manual template management and versioning
