If you switch between development projects which expect different environments, specifically different runtime versions or ambient libraries, or you are tired of all kinds of cumbersome environment configurations, vfox is the ideal choice for you.

vfox is a cross-platform version manager(similar to nvm, fvm, sdkman, asdf-vm, etc.), extendable via plugins. It allows you to quickly install and switch between different environment you need via the command line.

• cross-platform support (Windows, Linux, macOS)
• single CLI for multiple languages
• consistent commands to manage all your languages
• support Global、Project、Session scopes when switching versions
• simple plugin system to add support for your language of choice
• automatically switches runtime versions as you traverse your project
• shell completion available for common shells (Bash, Zsh, Powershell)
• it's faster than asdf-vm, and offers more simple commands and genuine cross-platform unification. see Comparison with asdf

For detailed installation instructions, see Quick Start

echo 'eval "$(vfox activate bash)"' >> ~/.bashrc
echo 'eval "$(vfox activate zsh)"' >> ~/.zshrc
echo 'vfox activate fish | source' >> ~/.config/fish/config.fish

# For PowerShell:
# 1. Open PowerShell Profile:
New-Item -Type File -Path $PROFILE # Just ignore the 'file already exists' error.
Invoke-Item $PROFILE
# 2. Add the following line to the end of your $PROFILE and save:
Invoke-Expression "$(vfox activate pwsh)"

Remember to restart your shell to apply the changes.
