I wish it was unnecessary.

I think most people get around this limitation by working in the Main REPL module and only typing/executing full function calls defined in their package (Method 1 in [this link](https://discourse.julialang.org/t/how-to-use-vscode-and-repl-to-write-and-test-a-package/78818/50)), but that method doesn’t work very well if you need to test individual lines of your package code (rather than entire functions). Changing your REPL module is the only way I have found to do that.

I’m happy to be proven wrong and shown something simpler, but I’ve been asking about this for a long time, and no one has given me a good answer:

I don’t understand the proper way to add my package and its dependencies to the REPL namespace or the proper way to juggle between the Main and MyPackage modules. I keep getting errors that variables, functions, or packages are undefined. I just want the simplest, foolproof workflow. Open MyPackage folder in VSCode made with PkgTemplates.jl. Start …
