Can't seem to get Revise to work in vscode

[clintonTE]

I'm probably doing something wrong here, but I'm not sure what it is. Hard to do a traditional MWE in this case, but I'll write down the simplest procedure I can think of.

First do the following in some random directory:

] generate mwe
] activate .

Edit mwe.jl in the src directory to read:

module mwe

function func()
  println("hello")
end

end # module

At this point, open vscode if it is not already open. Then in the root directory (using vscode), create a file called mwescripts.jl with the following:

using Revise, Pkg

if !isdefined(Main, :FIRST_RUN)
    Pkg.activate(pwd())
    FIRST_RUN = false
end

using mwe

mwe.func()

Running mwescripts.jl in a new repl gives:

hello

So far, so good. Then make the following change to the mwe.jl file

module mwe

function func()
  println("hello again")
end

end # module

running mwescripts.jl again gives:

hello

Of course, re-starting the Repl gives the correct answer.

Running Windows 10, Julia 1.1.1. Revise passed tests.

I suspect this is a user error rather then a bug, but any help would be appreciated.

EDIT: I should add that I tried using PkgTemplates and various methods for loading the modules in mwescripts.jl but nothing has worked.

Also for good measure, here are the results after following the debugging instructions:

Revise.LogRecord(Debug, DeleteMethod, Action, Revise_4ac0f476, "C:\Users\Clinton\.julia\packages\Revise\agmgx\src\Revise.jl", 226, (time=1.564013467903e9, deltainfo=(Tuple{typeof(mwe.func)}, MethodSummary(:func, :mwe, Symbol("C:\\Users\\Clinton\\Dropbox\\Projects\\mwe\\src\\mwe.jl"), 4, Tuple{typeof(mwe.func)}))))
Revise.LogRecord(Debug, Eval, Action, Revise_9147188b, "C:\Users\Clinton\.julia\packages\Revise\agmgx\src\Revise.jl", 276, (time=1.56401346808e9, deltainfo=(mwe, :(function func()
      #= C:\Users\Clinton\Dropbox\Projects\mwe\src\mwe.jl:4 =#
      println("hello again")
  end))))

I love VSCode but haven't used it much since the interpreter/debugger started working in Juno, so perhaps I'm not doing this the same way you are. So here's a screenshot:

If you have more info about how you're running that script, I'm happy to look further.

If you haven't seen this page, might it help?

I use Juno mostly now too, but I love the code outline features of VSCode, so I periodically try to get it going.

I tried it the way you ran it and got the same result as you. I think the issue is the f5 - Start Debugging command in VSCode. When running the files straight using include statements, it seems to work. Here is how I have it set up after I hit f5 the first time:

And then again after modifying the second file:

I could but wrong, but I don't think I need to touch startup.jl since I am using Revise explicitly.

I can replicate this. The way Revise works is to take over the REPL and call revise before executing each statement. With IJulia and Atom we have hooks:

• https://github.com/timholy/Revise.jl/blob/26a55b75aeebb374908e7cfddc8f4436bf37e98e/src/Revise.jl#L1043-L1044
• https://github.com/timholy/Revise.jl/blob/26a55b75aeebb374908e7cfddc8f4436bf37e98e/src/Revise.jl#L1088-L1098

Is there something similar for VSCode we can do?

Not without changes to the VSCode extension here and here (and maybe elsewhere).
