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)
• consistent commands to manage all your languages
• supports different versions for different projects, different shells, and globally.
• simple plugin system to add support for your runtime of choice
• automatically switches runtime versions as you traverse your project
• support for existing config files .node-version, .nvmrc, .sdkmanrc for easy migration
• shell completion available for common shells (Bash, ZSH, Powershell, Clink)

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:
if (-not (Test-Path -Path $PROFILE)) { New-Item -Type File -Path $PROFILE -Force }
echo 'Invoke-Expression "$(vfox activate pwsh)"' >> $PROFILE

# For Clink:
# 1. Install clink: https://github.com/chrisant996/clink/releases
#    Or Install cmder: https://github.com/cmderdev/cmder/releases
# 2. Find script path: clink info | findstr scripts
# 3. copy internal/shell/clink_vfox.lua to script path

# For Nushell:
vfox activate nushell $nu.default-config-dir | save --append $nu.config-path

Remember to restart your shell to apply the changes.
