UVFile 0.2.0

Like Brewfile but for UV

uvfile

Tools management for uv. Think Brewfile, but for Python CLI tools.

Note: Most of this tool, was written by Pseudocoder and the most of the readme was written by Claude based on my design and requirements. It works, but the implementation has room for improvement. I focused on the interface and user experience while delegating the implementation details to the LLM.

uv tool install uvfile

Why?

You want to track and sync your globally installed Python CLI tools across different environments, but uv tool install doesn't provide a way to save and restore tool states. With uvfile you can:

• Initialize a manifest of your system-wide Python tools
• Sync tools across different machines
• Track tool versions and their extras
• Share common tooling within teams while allowing personal tools

Usage

Initialize UVFile from currently installed tools

uvfile init

Install tools from UVFile

uvfile sync                  # Install missing tools
uvfile sync --pin            # Install and match exact versions
uvfile sync --force          # Force reinstall all tools in UVFile
uvfile sync --clean          # Remove tools unlisted in UVFile
uvfile sync --pin --clean
uvfile sync --force --clean

Combine sync options

uvfile sync --pin --clean
uvfile sync --force --clean

Preview changes

Add --dry-run to sync commands

uvfile sync --force --clean --dry-run

Would run: uv tool uninstall cowsay
Would run: uv tool install aider-chat --python python3.12 --reinstall
Would run: uv tool install cookiecutter --reinstall
Would run: uv tool install lefthook --reinstall
Would run: uv tool install poetry --reinstall
Would run: uv tool install project-mapper@https://github.com/blakesims/project-mapper.git --reinstall
Would run: uv tool install pypyp --reinstall
Would run: uv tool install ruff --reinstall
Would run: uv tool install type-ignore@https://github.com/cleder/type-ignore.git --reinstall
Would run: uv tool install uvfile --reinstall

Shell Integration

Add this to your shell config:

if command -v uvfile >/dev/null 2>&1; then
  source <(uvfile env)
fi

This will:

• Auto-update UVFile after uv tool install/upgrade
• Add uv file command as an alias for uvfile
• Add shell completions

Use Cases

Multiple Machines

Keep tools in sync across different computers:

On main machine

uvfile init
git add UVFile
git commit -m "Add my local uv tools via UVFile"
git push

On other machines

git pull
uvfile sync --pin    # Install while preserving existing tools

Team Standards

Share common tooling while allowing personal tools:

uvfile --uvfile ~/work/project/UVFile sync --pin   # Install team tools, keep personal ones

CI/CD

Ensure consistent tooling in CI:

steps:
  - uses: actions/checkout@v4
  - run: |
      curl -L https://github.com/astral-sh/uv/releases/latest/download/uv-installer.sh | sh
      uvfile sync

UVFile Format

UVFile uses a simple format that mirrors uv tool install commands:

ruff>=0.2.0 --python 3.11
mypy==1.8.0
black --with tomli --with typing-extensions>=4.0
pdm --with-editable ./dev-tools/pdm-plugin

Supports:

• Version constraints
• Python version specification
• Additional dependencies via --with
• Editable installs via --with-editable
• Git repositories
• Local directories

Environment Variables

• UVFILE_PATH: Override the default UVFile location (defaults to ./UVFile)

Limitations

• Doesn't provide a way to merge different UVFiles: you can use multiple UVFiles via different sync options, but there's no way to partially update UVFile, except for manual edits, of course (PRs welcome).
• Doesn't support all extra arguments (PRs welcome).
