Code Editor Options

To edit model code, you can either use a text editor, such as TextPad, or alternatively, you can use Visual Studio Code (VS Code) as a customizable code editor that can be made aware of the Julia programming language.

Using VS Code as IDE

Whereas VS Code is technically a code editor, when it is configured with the official Julia extension, it provides all the functions of a dedicated Integrated Development Environment (IDE). It allows programmers an interface to write, edit, test, and debug code in one application, enjoying various benefits such as an integrated REPL, code completion, graphical debugger, and code navigation.
