uv-shell-hook 0.1.6

This package provides a shell hook for uv allowing activating and deactivating virtual environments.

uv-shell-hook

A cross-platform shell integration for uv that adds convenient uv activate and uv deactivate commands to manage Python virtual environments across different shells and operating systems.

Features

• Cross-platform support: Works on Linux, macOS, and Windows
• Multi-shell support: bash, zsh, Fish, PowerShell, and Windows CMD
• Consistent interface: Same uv activate and uv deactivate commands across all shells
• Virtual environment discovery: Automatically finds virtual environments in multiple locations

Installation

$ uv tool install uv-shell-hook
$ uv-shell-hook --help

# or use it with uvx directly

$ uvx uv-shell-hook --help

Quick Start

Choose your shell and follow the setup instructions below:

Bash

Add the uv function to your shell:

# Add to ~/.bashrc or ~/.bash_profile
eval "$(uv-shell-hook bash)"

Or manually add the function:

uv-shell-hook bash >> ~/.bashrc
source ~/.bashrc

Zsh

Add the uv function to your shell:

# Add to ~/.zshrc
eval "$(uv-shell-hook zsh)"

Or manually add the function:

uv-shell-hook zsh >> ~/.zshrc
source ~/.zshrc

Fish

Add the uv function to your shell:

# Add to ~/.config/fish/config.fish
uv-shell-hook fish | source

Or manually add the function:

uv-shell-hook fish >> ~/.config/fish/config.fish

PowerShell

Add the uv function to your PowerShell profile:

# Add to your PowerShell profile (run $PROFILE to see location)
uv-shell-hook powershell | Out-String | Invoke-Expression

Or save it permanently:

uv-shell-hook powershell | Add-Content $PROFILE

Windows CMD

Save the batch script and add it to your PATH:

# Save the batch script
uv-shell-hook cmd > uv.bat

# Move to a directory in your `PATH` (e.g., C:\Windows\System32 or create a local bin directory)
move uv.bat C:\Users\%USERNAME%\bin\

Make sure the directory containing uv.bat is in your system PATH.

Usage

Once installed, you can use the enhanced uv commands in any supported shell:

Activate a Virtual Environment

The uv activate command will search for virtual environments in the following locations (in order):

1. <path>/.venv - Local .venv directory
2. <path> itself (if it ends with .venv)
3. ~/.virtualenvs/<name> - Named environment directory

# Activate virtual environment in current directory
uv activate

# Activate virtual environment in specific path
uv activate ./my-project

# Activate virtual environment by name from ~/.virtualenvs/my-project
# i.e. mimic `workon myproject` from virtualenvwrapper or `conda activate myproject` from conda
uv activate my-project

# Activate specific .venv path
uv activate /path/to/project/.venv

Deactivate Virtual Environment

# Deactivate currently active virtual environment
uv deactivate

Other uv Commands

All other uv commands work exactly as before:

uv init
uv add requests
uv run python script.py
uv sync
# ... any other `uv` command

Troubleshooting

If you encounter issues, try the following:

• Ensure the shell configuration file is sourced correctly (e.g., source ~/.bashrc or source ~/.zshrc).
• Check that the uv-shell-hook command is available in your PATH.
• Verify that the virtual environment exists in the expected location.
• If using Fish, ensure you have the latest version of Fish shell that supports the syntax used.
• For PowerShell, ensure your execution policy allows running scripts (Set-ExecutionPolicy RemoteSigned).
• If you have issues with CMD, ensure the uv.bat file is in a directory included in your system PATH.
• Check the uv documentation for any updates or changes to command usage.
• If you have custom virtual environment locations, ensure they are correctly set in your shell configuration.
