Odin Version Manager

Important

OVM is no longer being maintained. I recommend installing Odin by cloning the repo and building it yourself, per the official docs. If you would like to take ownership of OVM and continue its development/maintenance, you may open an issue here.

Odin Version Manager (ovm) is a tool for managing your Odin installs. With Odin being pre-1.0 the closest thing to a "regular release" are the monthly releases, and those are currently bugged on Linux. While OVM does require that you have the dependencies required to build Odin from source, it handles the downloads, extraction, and actual build for you.

At present, OVM is barely more than an automation for downloading and building the Odin compiler (and Odin Language Server), if I'm being honest. However, the plan is to adapt this tool as the language grows, eventually being a fully fledged version manager.

This tool is *ahem* heavily inspired by ZVM. In fact, Tristan gave me his blessing to rip off ZVM so that's what I did. If you find OVM useful, please do go check out ZVM and give Tristan some love. He's done some great work over there (and over here, technically).

Installing OVM

OVM lives entirely in $HOME/.ovm on all platforms it supports. Inside of the directory, OVM will download new Odin versions and symlink whichever version you specify with ovm use to $HOME/.ovm/bin. You should add this folder to your path. OVM's installer will add OVM to $HOME/.ovm/self. You should also add this directory as the environment variable OVM_INSTALL. The installer should handle this for you automatically if you're on *nix systems, but you'll have to manually do this on Windows. You can then add OVM_INSTALL to your path.

If you don't want to use OVM_INSTALL (like you already have OVM in a place you like), then OVM will update the exact executable you've called upgrade from.

Linux, BSD, MacOS, *nix

curl https://raw.githubusercontent.com/dogue/ovm/master/install.sh | bash

Then add OVM's directories to your $PATH

echo "# OVM" >> $HOME/.profile
echo export OVM_INSTALL="$HOME/.ovm/self" >> $HOME/.profile
echo export PATH="$PATH:$HOME/.ovm/bin" >> $HOME/.profile
echo export PATH="$PATH:$OVM_INSTALL/" >> $HOME/.profile

Windows

If you're on Windows, please grab the latest release.

Putting OVM on your Path

OVM requires a few directories to be on your $PATH. If you don't know how to update your environment variables permanently on Windows, you can follow this guide. Once you're in the appropriate menu, add or append to the following environment variables:

Add

• OVM_INSTALL: %USERPROFILE%\.ovm\self

Append

• PATH: %USERPROFILE%\.ovm\bin
• PATH: %OVM_INSTALL%

TODO!

ovm on the Arch AUR is a community maintained package, and may be out of date.

Why should I use OVM?

While Odin is still pre-1.0 if you're going to stay up-to-date with the master branch, you're going to be downloading Odin quite often. You could do it manually, having to scoll around to find your appropriate version, decompress it, and install it on your $PATH. Or, you could install OVM and run ovm i master every time you want to update. ovm is a static binary under a permissive license. Whether you're on Windows, MacOS, Linux, a flavor of BSD, or Plan 9 ovm will let you install, switch between, and run multiple versions of Odin.

Contributing and Notice

ovm is alpha software. Pre-v1.0.0 any breaking changes will be clearly labeled, and any commands potentially on the chopping block will print notice. The program is under constant development, and the author is very willing to work with contributors. If you have any issues, ideas, or contributions you'd like to suggest create a GitHub issue.

How to use OVM

Install

ovm install <version> 
# Or
ovm i <version>

Use install or i to download a specific version of Odin. To install the latest monthly release, use "latest". To install from the master branch, use "master".

# Example
ovm i master

Install OLS with OVM

You can install OLS with your Odin download! To install OLS with OVM, simply pass the -l/--lsp flag with ovm i. For example:

ovm i master -l

Switch between installed Odin versions

ovm use <version>

Use use to switch between versions of Odin. Also available as switch.

# Example
ovm use master

List installed Odin versions

# Example
ovm ls

Use ls to list all installed version of Odin. Also available as list.

List all versions of Odin available

ovm ls --remote

The -r/--remote flag will list the versions of Odin available for download rather than those locally installed.

Uninstall a Odin version

# Example
ovm rm dev-2023-12

Use remove or rm to remove a locally installed version from your system.

Upgrade your OVM installation

You can upgrade your OVM installation from ovm. Just run:

ovm upgrade

The latest version of OVM should install on your machine, regardless of where your binary lives (though if you have your binary in a privileged folder, you may have to run this command with sudo).

Print program version
