Cookiecutter

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
