Python Monorepos

Utilities for working with monorepos in Python.

Installation

git clone https://github.com/JenspederM/uvmono
cd uvmono
pip install .

Usage

# Show help
uvmono --help

# List all packages in the monorepo
uvmono list

# Add a package to the monorepo
uvmono new <package-name>

# Add dev-containers for a package in the monorepo
uvmono add-devcontainer <package-name>

# Add dev-containers for all packages in the monorepo
uvmono add-devcontainer --all

# Create a Matrix Strategy for a GitHub Actions workflow
uvmono matrix_strategy <key-name>
# Returns a JSON object with the matrix strategy for the packages in the monorepo:
# {
#   "matrix": {
#     "inputs": [ 
#       { 
#           "path": "packages/package1", 
#           "name": "package1", 
#           "dependencies": ["package2"], 
#           "filter":  "..." # outputs `is_changed` in dorny/paths-filter@v3
#       },
#       ...
#     ]
#   }
# }

Examples

List all packages in the monorepo

uvmono list

Add a package to the monorepo

Create a new package in the monorepo with the name my-package.

uvmono new my-package

This will automatically create a new directory packages/my-package with the following structure:

.
└── packages/my-package
    ├── src
    │   └── my_package
    │       └── __init__.py
    ├── tests
    │   ├── __init__.py
    │   ├── conftest.py
    │   └── test_main.py
    ├── pyproject.toml
    └── README.md

Create a Matrix Strategy for a GitHub Actions workflow

Create a matrix strategy for a GitHub Actions workflow with the key inputs.

uvmono matrix_strategy inputs

This will automatically generate a matrix strategy for the packages in the monorepo, which can be used in a GitHub Actions workflow:
