An experimental Julia version manager

Juliaup - Julia version manager and Windows Store installer

This repository contains an experimental MSIX installer for Julia for the Windows Store.

The installer also bundles a full Julia version manager called juliaup. One can use juliaup to install specific Julia versions, it alerts users when new Julia versions are released and provides a convenient Julia release channel abstraction. The installer is published to the Windows Store and you can try it from here.

Using Juliaup

If you want to try it, here is what you should do:

• Make sure you don't have any version of Julia on your PATH. Juliaup will handle all PATH related aspects of your Julia installation.
• Install Julia from the Windows Store here.

Once you have that installed, julia is on the PATH, there is a start menu shortcut and it will show up as a profile in Windows Terminal. Any of those will start Julia. The VS Code extension will also automatically find this Julia installation.

Here are some of the things you can do with juliaup:

• juliaup update installs the latest availabe Julia version for all your channels.
• juliaup update release updates the release channel to the latest version.
• juliaup status shows you which Julia versions you have installed and which one is configured as the default.
• juliaup add 1.5.1 adds Julia 1.5.1 to your system (it can then be launched via the command julia +1.5.1).
• juliaup default 1.5.3 configures the julia command to start Julia 1.5.3.
• juliaup default 1.6 configures the julia command to start the latest 1.6.x version of Julia you have installed on your system (and inform you if there is a newer version in 1.6.x available).
• juliaup default release configures the julia command to start the latest stable version of Julia (this is also the default value).
• juliaup remove 1.5.3 deletes Julia 1.5.3 from your system.
• juliaup add 1.6.1~x86 installs the 32 bit version of Julia 1.6.1 on your system.
• juliaup default 1.6~x86 configures the julia command to start the latest 1.6.x 32 bit version of Julia you have installed on your system.
• juliaup link dev ~/juliasrc/julia configures the dev channel to use a binary that you provide that is located at ~/juliasrc/julia. You can then use dev as if it was a system provided channel, i.e. make it the default or use it with the + version selector. You can use other names than dev and link as many versions into juliaup as you want.
• juliaup shows you what other commands are available.

To launch the Julia version in channel release, run julia +release in your terminal.
The available system provided channels are:

• release: always points to the latest stable version.
• lts: always points to the latest long term supported version.
• beta: always points to the latest beta version if one exists. If a newer release candidate exists, it will point to that, and if there is neither a beta or rc candidate available it will point to the same version as the release channel.
• rc: same as beta, but only starts with release candidate versions.
• specific versions, e.g. 1.5.4.
• minor version channels, e.g. 1.5.
• major version channels, e.g. 1.

All of these channels can be combined with the ~x86 or ~x64 suffix to download a specific platform version.

This entire system around juliaup installs Julia versions into ~/.julia/juliaup. If you want to restart from scratch, just delete that entire folder.
