history

Project history and usage

Uru is a lightweight, multi-platform Ruby environment manager written in Go. Its README describes it as a minimal command-line tool for using multiple MRI, JRuby, and Rubinius installations across 32-bit and 64-bit Linux, OS X, and Windows systems.

Project history

The Bitbucket repository was created in April 2013. Early tags followed quickly through 2013, and the README's current version line identifies 0.8.5, which Bitbucket tag metadata dates to March 2018. The design pitch contrasts Uru with RVM, rbenv, pik, and chruby by emphasizing a small multi-platform core.

Adoption history

The README documents direct binary installation and mentions Scoop, Chocolatey, Cygwin/MSYS2, Fish shell, Linux, and OS X installation paths. In this batch, source_facts lists Homebrew packaging, so package-manager adoption is present but narrower than better-known Ruby managers.

How it is used

Users install the uru_rt executable, run an admin install command to integrate it with their shell, register Ruby installations, then switch between tags with commands such as uru ls, uru 174, or uru sys. The README examples show using Uru to run commands across registered Rubies and inspect gem availability.

Why package nerds care

Uru is interesting to package nerds as a cross-platform alternative in a niche where many tools grew around Unix shell integration. Its small Go binary and Homebrew formula make it easy to package, while the runtime-switching behavior overlaps with the version-manager ecosystem.
