You’re looking at the Atom editor, version 1.40.1, running Juno 0.7.2. I almost didn’t get to this point. I first downloaded Atom from its main web site (https://atom.io), unzipped the file, and move the application into my local Application folder. I then started it up via Launchpad and attempted to install Juno (uber-juno). Juno failed. I tried a number of different ways to get Juno to install, and every time Juno installation failed. That was late last night, and when midnight chimed I called it a day and went to bed.
Tonight, I removed that installation and instead installed Atom via brew (https://brew.sh) using
brew cask install atom. Installing Atom via brew seemed to do the trick. I was able to install uber-juno using the brew-installed version of Atom with no problems at all. As you can see it’s up and running and using Julia 1.1.1, the version I installed last night. I’m finally back to the tool set I used a year ago with Julia 1.0. Let’s see how this goes.
