# Virtual Environment Manager
A comprehensive Python package for managing virtual environments, providing equivalent functionality to the bash `venv.sh` script with enhanced features.
## Features
- **Environment Creation**: Create virtual environments using `uv`, `python3`, or `python` with automatic fallback
- **Smart Activation**: Activate environments with directory mapping for auto-activation
- **Package Management**: Install, uninstall, update, and search packages using `uv` or `pip`
- **History Tracking**: Track directory-to-environment mappings for automatic activation
- **Cross-Platform**: Works on Linux, macOS, and Windows with Python 3.7+
## Installation
### From Source
```bash
pip install git+https://github.com/anhvth/uv-virtual-environs-manager
```
### From PyPI (once published)
```bash
pip install pyve
```
## Quick Start
```bash
# Create a new virtual environment
ve create myproject --python=3.12
# Activate an environment (creates directory mapping)
atv myproject
# List all environments
ve list
# Install packages
ve install requests numpy
# Show environment info
ve info
# Auto-activation: when you cd back to this directory,
# the environment will be suggested for activation
```
## Commands
### Main Commands
- `ve create <name> [options]` - Create a new virtual environment
- `ve activate <name>` - Activate a virtual environment
- `ve deactivate` - Deactivate current virtual environment
- `ve list` - List all virtual environments
- `ve delete <name>` - Delete a virtual environment
- `ve info` - Show current virtual environment info
- `ve which <name>` - Show path to virtual environment
### Package Management
- `ve install <pkg>...` - Install packages in active venv
- `ve installed` - List installed packages in active venv
- `ve uninstall <pkg>...` - Uninstall packages from active venv
- `ve search <pkg>` - Search for packages on PyPI
- `ve update <pkg>...` - Update packages in active venv
- `ve run <cmd>...` - Run command in active venv
### History & Auto-Activation
- `ve history` - Show directory → environment mappings
- `ve clear-history` - Clear all atv history
- `atv <name>` - Activate with directory mapping (alias for `ve activate`)
### Utility Commands
- `create_env <name>` - Alternative create command
- `install_uv` - Install uv package manager
## Configuration
The package uses the following files for tracking:
- `~/.venv_all_env` - Global environment tracking
- `~/.config/atv_history` - Directory-to-environment mappings
- `~/.venvs/` - Default location for virtual environments
- `~/.last_venv` - Last activated environment
## Shell Integration
For full shell integration (auto-activation on directory change), add this to your shell configuration:
### Zsh
```bash
# Add to ~/.zshrc
eval "$(ve shell-integration zsh)" # Future feature
```
### Bash
```bash
# Add to ~/.bashrc
eval "$(ve shell-integration bash)" # Future feature
```
## Auto-Activation
When you use `atv <name>` to activate an environment, the current directory is mapped to that environment. When you navigate back to that directory later, you'll be reminded to activate the environment.
## Examples
```bash
# Create a new project environment
ve create myproject --python=3.12
cd /path/to/myproject
# Install dependencies
ve install requests flask pytest
# Later, when you cd back to the project
cd /path/to/myproject
# The tool will remind you about the mapped environment
# View all mappings
# Clean up
ve delete myproject
```
## Differences from Shell Version
- **Shell Integration**: The Python version can't directly modify the current shell environment. It provides activation commands to run.
- **Auto-Activation**: Requires shell integration for automatic activation on directory change.
- **Browser Opening**: Package search opens browser when available.
## Development
### Local Development
```bash
# Clone and install in development mode
git clone <repo-url>
cd virtual_envs_manager
pip install -e .
# Run tests (if available)
python -m pytest
# Type checking
mypy pyve/
```
