💖 MULTIRUBY_SETUP — the girlies' guide 💖

okay so bestie, you know how you've got like a million rubies and zero chill about it? this is the manual page for multiruby_setup, straight out of the Debian GNU System manual, section 1. it's giving "let me hold your hand while you juggle interpreters." 🫶

✨ NAME ✨

multiruby_setup — a script to help you manage multiruby 💅

🌸 SYNOPSIS 🌸

multiruby_setup [-h|cmd|spec...]

multiruby_setup mri:svn:current

🦋 DESCRIPTION 🦋

Use multiruby_setup to manage your installed versions of ruby. no cap, that's literally its whole job. it's here so you can use the multiruby command to run anything you want on multiple versions of ruby — main character energy across every interpreter you've got. 👑

The various versions are installed in a subdirectory of .multiruby in your home directory. yes, your home directory. that's where they live. 🏠

🎀 OPTIONS 🎀

cmds 💫

the commands, the moves, the whole routine:

  • -h, --help, help — show this help. (you're welcome ✨)
  • build — build and install everything. used internally. 🛠️
  • clean — clean scm build dirs and remove non-scm build dirs. spring cleaning fr fr 🧹
  • list — print installed versions. the vibe check of your ruby shelf 🌈
  • rm:$version — remove a particular version. bye bestie 💀
  • rubygems:merge — symlink all rubygem dirs to one dir. one dir to rule them all 🎀
  • tags — list all tags from svn. 👑
  • update — update svn builds. 🔥
  • update:rubygems — update rubygems and nuke install dirs. NUKE. she said what she said 💥

specs 🌟

the specs, aka the little incantations you type to summon exactly which ruby you want:

  • the_usual — alias for latest versions from tar + rubygems. the standard order, iykyk 🍓
  • mri:svn:current — alias for mri:svn:releases and mri:svn:branches. two for the price of one 😭
  • mri:svn:releases — alias for supported releases of mri ruby. the responsible ones 💜
  • mri:svn:branches — alias for active branches of mri ruby. the ones still cooking 🧚
  • mri:svn:branch:$branch — install a specific $branch of mri from svn. 🌸
  • mri:svn:tag:$tag — install a specific $tag of mri from svn. 🏷️
  • mri:tar:$version — install a specific $version of mri from tarball. 📦

environment variables 🌈

  • GEM_URL — url for rubygems tarballs
  • MRI_SVN — url for MRI SVN
  • RUBY_URL — url for MRI tarballs
  • VERSIONS — what versions to install
  • RUBYOPT is cleared on installs.
not me reminding you that RUBYOPT gets cleared on installs. it does. every time. that's just how she is. 🙈

💀 NOTES 💀

  • you can add a symlink to your rubinius build into ~/.multiruby/install
  • I need patches/maintainers for other implementations.
lowkey the second bullet is a call for help. the maintainers are asking. if you've got patches, you've got a moment, you've got a destiny. 🫶
