mxdev-uv-pyproject-updater 0.1.0

An mxdev hook to update pyproject.toml for uv workflows

mxdev-uv-pyproject-updater

An mxdev extension hook that automatically updates pyproject.toml during the mxdev write phase to support uv workflows.

Installation

You must install this package in the same environment as mxdev.

If you are using uv to run mxdev globally, you can install the hook via uv tool install:

uv tool install mxdev --with mxdev-uv-pyproject-updater

Or if you are running mxdev via a local virtual environment:

uv pip install mxdev mxdev-uv-pyproject-updater

Usage

Because it registers an mxdev entry point, this hook runs automatically whenever you run mxdev. It will automatically detect packages defined in your mx.ini file and write the corresponding configuration to your pyproject.toml file.

Features

1. Automatic uv Source Mapping It natively configures the [tool.uv.sources] table in your pyproject.toml. It handles mxdev's absolute vs relative directories and automatically respects the install-mode setting (editable, fixed, or skip). It perfectly supports mxdev subdirectory parameters too.

   [tool.uv.sources]
   "plone.app.discussion" = {path = "sources/plone.app.discussion", editable = true}
   

2. Smart Dependency Injection The hook safely inserts your checked-out packages directly into your [project] dependencies array.

   It implements strict PEP 503 normalization (converting -, _, and . equivalently) to intelligently ensure packages aren't duplicated, even if the dependency is already specified in your pyproject.toml with version specifiers or extras.

   [project]
   dependencies = [
       "plone.app.discussion"
   ]
   

3. Format Preservation Built on tomlkit, it safely updates pyproject.toml while perfectly preserving all your existing user formatting, arrays, spacing, and comments.
