uru / BashOnWindows

Overview

Starting with the 0.7.7 release, uru includes support for Windows users using bash-like and fish shells from Cygwin or MSYS2 or git-bash from Git for Windows.

The goal is to enable Windows users to use uru from cmd.exe, powershell, and bash shells with no interoperability issues. Specifically, one should be able to use uru to register an installed ruby from cmd.exe or powershell and use the same ruby from bash or fish, with no changes to uru's persisted metadata. There may be corner case usage scenarios with bash-on-windows environments that cannot or will not be resolved.

Installing Uru in Cygwin/MSYS2 Bash

To enable uru to be used from both Windows shells and Cygwin/MSYS2 shells, one must install uru in both environments. The recommended installation process is to first install uru in your Windows environment, then install uru in your Cygwin/MSYS2 environment.

  • First, open up a new cmd.exe or powershell instance and install uru for Windows
:: Extract uru_rt.exe to a dir already on PATH and install. For example, assuming
:: uru_rt.exe was extracted to C:\tools already on your PATH, install uru like
C:\tools>uru_rt admin install

:: [OPTIONAL] If you have a pre-existing ruby already on PATH from cmd.exe
:: initialization, you can register it as the "system" ruby. A "system" ruby is
:: almost always a bad idea.
C:\tools>uru_rt admin add system
  • Second, open up a separate new bash instance and install uru for Cygwin/MSYS2
# Extract uru_rt to a dir already on PATH and install. For example, assuming
# uru_rt was extracted to ~/bin already on your PATH, install uru like
$ cd ~/bin && chmod +x uru_rt

# Append to ~/.profile on Ubuntu, or to ~/.zshrc on Zsh
$ echo 'eval "$(uru_rt admin install)"' >> ~/.bash_profile

# For fish shells
$ echo 'uru_rt admin install | source' >> ~/.config/fish/config.fish

# Restart the shell
$ exec $SHELL --login
  • Third, register your previously installed rubies by executing the uru admin add ... command from either shell environment. You can now use uru from either your Window's shell or your Cygwin/MSYS2 shell environments to use any of the registered rubies.
