repopy

A modular, cross-platform Python CLI workspace manager and developer tooling suite designed to automate reproducible local scaffolding, virtual environment creation, and remote repository synchronization.

🌟 Key Features

• Lifecycle Project Scaffolding (repopy init): Provisions clean directory structures, dedicated virtual environments, automated .gitignore and README.md templates, and PEP 621 pyproject.toml or requirements.txt configs.

• Smart Remote Cloning (repopy clone): Clones remote Git repositories, creates isolated .venv environments, previews declared dependencies, and installs them interactively or via flags.

• Upstream Linking (repopy link): Instantly connects an unlinked local workspace to a remote Git upstream, staging files, executing initial commits, and pushing to the default branch in one step.

• Artifact Pruning (repopy clean): Recursively scans and purges transient build directories, bytecode caches, and test artifacts (__pycache__, .pytest_cache, .coverage, build/, dist/, .ruff_cache, .mypy_cache) with interactive safeguards and automated CI bypasses.

• Architectural Themes: Built-in layout presets (minimal, web_api, cli_package, data_science) tailored to modern packaging standards.

• Transactional Safety: Employs defensive rollback mechanisms (shutil.rmtree) to safely purge half-baked directories if setup fails midway, with standardized shell exit codes across all subcommands.

• Isolated & Tested: Fully decoupled architecture backed by a 1:1 mapped test suite with 100% branch test coverage.

🛠️ Architecture & Separation of Concerns

repopy is organized into single-responsibility layers:

• Presentation & Routing (cli.py, prompts.py, __main__.py): Evaluates native terminal arguments via argparse, orchestrates interactive prompt flows, and handles OS interrupts gracefully.

• Supervision (orchestrators.py): Broker layer executing lifecycle validation checks, branch sequencing, rollback triggers and command handoffs.

• Low-Level Engines (file_system.py, git_engine.py): Decoupled engines handling transactional directory allocations, venv isolation, dependency installation and direct subprocess execution.

• Validation & Translation (validators.py, dependencies.py, os_detector.py): Sanitizes names and paths, validates Git URLs, verifies host binaries (python, git), and resolves cross-platform paths.

📥 Installation

Install the latest release from PyPI:

pip install repopy

Alternatively, you can install the latest development version directly from the source:

git clone https://github.com/manatunga/repopy.git
cd repopy
pip install -e .

🚀 Usage Guide

1. Initialize a Project (repopy init)

Generate a new workspace interactively or via CLI flags:

# Interactive setup
repopy init my-app

# Non-interactive generation with a specific theme (-t/--theme and/or -s/--skip)
repopy init my-api -t web_api -s

# Initialize and immediately connect to a remote repository
repopy init my-cli -t cli_package --link <git-url>

Available Themes:

• minimal: Bare directory setup with requirements.txt.
• web_api: Layered service layout prepared for modern frameworks.
• cli_package: Modular structure configured with PEP 621 compliant pyproject.toml.
• data_science: Notebooks, data directories (raw, processed), and pipeline layout.

2. Clone a Remote Project (repopy clone)

Fetch a remote repository, provision a virtual environment, and manage dependencies:

# Interactive mode (previews requirements.txt and prompts for installation)
repopy clone <git-url>

# Custom directory name
repopy clone <git-url> -n custom-folder-name

# Auto-install dependencies without prompting (-i/--install)
repopy clone <git-url> -i

# Fetch and provision environment only (skip dependency installation)
repopy clone <git-url> --no-install

3. Link an Existing Workspace (repopy link)

Run inside an existing workspace to push tracking history to an upstream origin:

# Link with default initial commit message
repopy link <git-url>

# Link with custom commit message
repopy link <git-url> -m "feat: initial project structure"

4. Clean Artifacts (repopy clean)

Safely remove build, cache, and test leftovers across the workspace:

# Interactive mode: scans workspace, previews discovered targets, and prompts for confirmation
repopy clean

# Non-interactive mode: immediately purges all discovered artifacts (ideal for CI/CD pipelines) (-y / --yes)
repopy clean -y

Cleared Targets:

• Python Bytecode: __pycache__, *.pyc, *.pyo
• Testing & Coverage: .pytest_cache, .coverage, htmlcov/
• Packaging & Builds: build/, dist/, *.egg-info
• Type Checking: .mypy_cache, .ruff_cache

🧪 Testing & Continuous Integration

Run the test suite using pytest:

# Run unit tests
pytest -v

# Run with full coverage report
pytest --cov=repopy --cov-report=term-missing
