Getting the Julia extension for VS Code to work involves two steps: 1) Install VS Code and 2) install the Julia extension. In rare situations you also need to configure the extension to find your Julia installation.
Just head over to the VS Code homepage and follow the installation instructions for your platform. At the end of this step you should be able to start VS Code.
First, start VS Code. Inside VS Code, go to the extensions view either by executing the
View: Show Extensions command (click View->Command Palette...) or by clicking on the extension icon on the left side of the VS Code window.
In the extensions view, simply search for the term
julia in the marketplace search box, then select the Julia extension and click the install button. You might have to restart VS Code after this step.
If you have installed Julia into a standard location on Mac or Windows, or if the Julia binary is on your
PATH, the Julia VS Code extension should automatically find your Julia installation and you should not need to configure anything.
If the extension does not find your Julia installation automatically, or if you want to use a different Julia installation than the default one, you can set the
julia.executablePath to point to the Julia executable that the extension should use. In that case the extension will always use that version of Julia. To edit your configuration settings, execute the
Preferences: Open User Settings command (you can also access it via the menu
File->Preferences->Settings), and then make sure your user settings include the
julia.executablePath setting. The format of the string should follow your platform specific conventions, and be aware that the backlash
\ is the escape character in JSON, so you need to use
\\ as the path separator character on Windows.
