I am trying to debug my code in VS Code.  
Presenter in the video [JuliaCon 2020 | Using VS Code for Julia development | David Anthoff](http://www.youtube.com/watch?v=IdhnP00Y1Ks&t=16m59s) uses @run macro.  
I cannot find it/use it:

```julia
julia> @run MyModule.myFunction()
ERROR: LoadError: UndefVarError: @run not defined
in expression starting at REPL[19]:1

```

Thank you.

You need to run that line in the integrated REPL (the one opened with the `Julia: Start REPL` command).

Thank you. With integrated REPL I can run @run marco. However…

My function executes web service:

```julia
function run()
    HTTP.serve(requestHandler, "0.0.0.0", 8080)
end

```

When I set a breakpoint inside my requestHandler and use @run macro, Pause, Restart etc. buttons are nicely activated on top of VS Code. But when I call from outside on my service, execution doesn’t stop at the breakpoint (at any breakpoint), but it definitely runs, because it prints output to the integrated Julia REPL terminal.
