4.Launching Juno for JuliaPro

From within the LaunchPad window, Double-Click on the JuliaPro icon to start a Juno session.

Upon initially launching Juno, you will be presented with the following window.

Juno is a full-featured and easily extensible integrated development environment based on the Atom editor.

The previous screenshot shows the most important aspects of the Juno environment for working with Julia code:

  • The Editor Tab - A tab that is primarily used for developing longer segments of Julia code, as well as code that will be saved to a file. Multiple editor tabs can be opened within a single Juno session to develop multiple Julia files.
  • Julia REPL - The tab that is primarily used for executing Julia commands interactively and displaying textual results from those commands.
  • The Plots Tab - The tab used for display of visualizations produced by supported plotting packages.
  • The Workspace Tab - The tab used for displaying the values of variables and functions that are in the current Julia scope.
  • The Julia Toolbar - The primary toolbar containing buttons for controlling aspects of the use of Julia from within Juno.
  • The Julia Menu - An entry in the the Atom Menu that is specific to control of Julia from within Juno.
  • Documentation Tab - This tab provides a convenient way to access documentation in the Juno IDE, you can search for documentation of all imported Julia packages and you can also access Base Julia documentation using this tab.
  • The Atom Command Palette (not shown in the screenshot above) - A pop-up window that allows for searching all commands available from within an Atom/Juno session, including "julia" specific commands.

4.1 Using Juno

Naming convention for different layout (Panes) in Juno IDE can be seen below

You can start Julia by pressing enter in “Julia REPL” pane

By default, JuliaPro will download all the packages from , this website requires authentication, hence, you will go through the authentication process the first time you perform a Pkg operation; JuliaPro will open the authentication link in your default browser, once you successfully authenticate in your browser, JuliaPro will download a unique token for you and place it in the appropriate location. This token will be reused in your subsequent Pkg operations.

Once the URL link is open in your browser, you will be directed to authenticate by signing into either one of these accounts : LinkedIn or Gmail or GitHub or JuliaComputing account.

Once the authentication is done, you will get a message in browser saying "Authenticated. You may close this browser window now."

Your Pkg operation should continue as is, all your subsequent Pkg operations will use the token that JuliaPro just downloaded.

If the automated browser authentication is failing, then please report the issue to and follow below instructions as a fallback to manually download the token and place it in the appropriate location:


  1. Open following link in your browser:
  2. Once you open the URL link, you will be directed to authenticate by signing into either one of these accounts : LinkedIn or Gmail or GitHub or JuliaComputing account.

Once the authentication is done, your token.toml file download should begin immediately , if your download doesn’t begin automatically, you can always click on “here” URL link to download the token

Once you have token.toml , rename this file as auth.toml and then you can move this file to the machine where you have installed JuliaPro (If you're downloading token from a different machine), the default location to place this file is ~/.juliapro/JuliaPro_v1.5.1-1/servers/ i.e create following path .juliapro/JuliaPro_v1.5.1-1/servers/ in your home directory and place auth.toml in the path you just created. Once you place the file in this location, all subsequent Pkg and BinaryProvider.jl operations will use this token to authenticate the download from
