uv-shell-hook 0.1.0

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
• Smart virtual environment discovery: Automatically finds virtual environments in multiple locations
• Consistent interface: Same uv activate and uv deactivate commands across all shells
• Colorized output: Clear visual feedback with colored status messages

Installation

pip install uv-shell-hook

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>/.venv - Named environment in virtualenvs directory
4. ~/.virtualenvs/<name> - Named environment directory (uses $WORKON_HOME if set)

# 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/
uv activate myproject

# 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

Examples

Example 1: Project-local Virtual Environment

cd my-python-project
uv venv                    # Create .venv in current directory
uv activate                # Activate the .venv
# (my-python-project) $
uv add requests           # Install packages
uv deactivate             # Deactivate when done

Example 2: Named Virtual Environment

# Create a named environment
uv venv ~/.virtualenvs/data-analysis

# Activate from anywhere
cd /some/other/directory
uv activate data-analysis  # Activates ~/.virtualenvs/data-analysis/.venv

Example 3: Multiple Virtual Environments

# Work with different projects
uv activate web-app        # Activate ~/.virtualenvs/web-app/.venv
uv deactivate

uv activate data-science   # Activate ~/.virtualenvs/data-science/.venv
uv deactivate

uv activate ./local-project  # Activate ./local-project/.venv

Troubleshooting

Virtual Environment Not Found

If you get "Virtual environment directory not found", check:

1. The virtual environment exists in one of the search locations
2. You have the correct permissions to access the directory
3. The activation script exists in the Scripts/ (Windows) or bin/ (Unix) subdirectory

Function Not Available

Make sure you've properly added the shell function to your profile and restarted your shell or sourced the profile file.
