Unable to run or debug when using VSCode

The message “xxx is not defined in Main” means that Julia does not see the function.

You need to compile it first. You didn’t provide a full Minimal working example (MWE) with your full code but try the following:

  • Put the function in a file, e.g. myfuncs.jl
  • in another file, write include("myfuncs.jl"). Depending on where you put the file you might need to add the path, e.g. If it is in a subfolder “functions” it should be include("functions/myfuncs.jl")
  • Evaluate it/Send it to the REPL. You should see first a round arrow while julia compiles the function. If there is no error in your function you will see a tick mark on vs code on the line

Now julia should sees the function and you can call it.

This workflow is a bit dependent on how exactly you use VS code.

Consider using Revise if you want to change the function, then you use includet() instead of include()
