Installing Julia using Brew

It appears that brew does not have a Julia formula. This is quite surprising to me, am I missing something?

Apparently there's a brew tap that can be used instead (staticfloat/julia). Before going for that solution I wanted to know if that's supposed to be the most straightforward way to do so.

You can install Julia using cask:

$ brew cask install julia

$ brew cask info julia
julia: 0.4.2
Julia
http://julialang.org/
Not installed
https://github.com/caskroom/homebrew-cask/blob/master/Casks/julia.rb
==> Contents
  Julia-0.4.2.app (app)
  Julia-0.4.2.app/Contents/Resources/julia/bin/julia (binary)

To clarify, The Julia installation that you get if you go to https://julialang.org/downloads/ and download Julia 1.6.3 dmg for Mac is exactly the same as the installation that Homebrew's Cask currently gets, which is evidenced here: https://github.com/Homebrew/homebrew-cask/blob/master/Casks/julia.rb

However, Julia behaves differently once you've actually installed the Homebrew Julia 1.6.3 Cask versus the Julia 1.6.3 from https://julialang.org/downloads/. I first experienced this when trying to use PackageCompiler.jl to make a shippable application using Homebrew's Julia 1.6.3 Cask install. With this install, the app continued to fail despite all my efforts. When I switched to the Julia 1.6.3 dmg install from https://julialang.org/downloads/, the PackageCompiler app worked and was relocatable.

So just a heads up, these two methods install Julia differently on the system, resulting in Julia behaving differently in some cases.
