splurge-vendor-sync 2025.1.2

Vendor synchronization tool.

splurge-vendor-sync

A powerful CLI tool for one-way vendor synchronization of Python libraries and applications. Automatically synchronize internal package dependencies into your project's vendor directory with selective file filtering and automatic cleanup.

Features

• One-way synchronization: Clean removal and fresh copy of vendor packages
• Selective file filtering: Include only the file types you need (default: .py, .json, .yml, .yaml, .ini)
• Automatic cleanup: Removes outdated vendor files before syncing new ones
• Exclusion support: Automatically excludes __pycache__ and other build artifacts
• Version scanning: Scan vendored packages to extract version information with --scan
• Cross-platform: Works on Windows, Linux, and macOS
• Safe I/O: Uses deterministic newline normalization and secure path validation
• Clear error reporting: Domain-based exception hierarchy with actionable error messages

Quick Start

Installation

# From source
pip install -e .

# Or after packaging
pip install splurge-vendor-sync

Basic Usage

Synchronize a source package to your project's vendor directory:

splurge-vendor-sync \
  --source /path/to/splurge-vendor-sync \
  --package splurge_exceptions \
  --target /path/to/my-project/my_project

This will:

1. Remove all existing files from /path/to/my-project/my_project/_vendor/splurge_exceptions/
2. Copy all .py, .json, .yml, .yaml, .ini files from the source package
3. Preserve the directory structure
4. Exclude __pycache__ directories

With Custom Extensions

splurge-vendor-sync \
  --source /path/to/splurge-vendor-sync \
  --package splurge_exceptions \
  --target /path/to/my-project/my_project \
  --ext "py;json;yaml"

With Custom Vendor Directory

splurge-vendor-sync \
  --source /path/to/splurge-vendor-sync \
  --package splurge_exceptions \
  --target /path/to/my-project/my_project \
  --vendor "_vendored"

Scan Vendored Packages

# Scan for __version__ in all vendored packages
splurge-vendor-sync \
  --target /path/to/my-project/my_project \
  --scan

# Scan with custom version tag
splurge-vendor-sync \
  --target /path/to/my-project/my_project \
  --scan MY_VERSION

# Scan with custom vendor directory
splurge-vendor-sync \
  --target /path/to/my-project/my_project \
  --vendor custom_vendor \
  --scan

Exit Codes

• 0: Synchronization completed successfully
• 1: Runtime error (I/O failure, permission denied, etc.)
• 2: Validation error (invalid paths, missing arguments, etc.)

Common Scenarios

Sync after updating source package

# Re-run the same command - old files are automatically removed
splurge-vendor-sync \
  --source /path/to/splurge-vendor-sync \
  --package splurge_exceptions \
  --target /path/to/my-project/my_project

Sync multiple packages

# Create a script to sync all your vendored dependencies
splurge-vendor-sync --source /path/to/splurge-vendor-sync --package splurge_exceptions --target /path/to/my-project/my_project
splurge-vendor-sync --source /path/to/splurge-safe-io --package splurge_safe_io --target /path/to/my-project/my_project

Troubleshooting

Q: "File not found" error
A: Verify the --source and --target paths exist and the --package directory name is correct.

Q: "Permission denied" error
A: Ensure you have write permissions to the target directory.

Q: Files not being copied
A: Check that the file extensions match your --ext parameter (default: py;json;yml;yaml;ini)
