Folding long regions of code can improve readability and help getting a better view of what a file contains. As of now, Visual Studio Code does not provide a possibility to define custom folding rules (PR) and the default folding is rather unsatisfying when it comes to Julia source code.
Until we get custom folding in VS Code, I'm using Explicit Folding (v0.8.2) with the following settings in settings.json
Keep in mind the correct JSON syntax and don't forget the commas before and after each of the above blocks. Now, with my custom bindings for Fold All, Unfold All, Fold recursively, Unfold recursively (to be set in VS Code settings) this works more or less like that
