WebIO support for Visual Studio Code

[vchuravy]

Using the Jupyter extension in VSCode I get a:

Unable to load WebIO. Please make sure WebIO works for your Jupyter client. For troubleshooting, please see the WebIO/IJulia documentation.

I see this issue as well. I attempted to get WebIO to render in the Julia Extension Plot Pane by using

Base.show(io::IO, m::MIME"juliavscode/html", x::Node) = print(io, WebIO.htmlstring(x))

Then, when displaying a node the plot pane opens with the message:

WebIO not detected.

It's up to the VSCode extension to provide integration with WebIO (since otherwise there's no way WebIO can know how to communicate with the Julia process).

IJulia is the only "first class" integration that we provide.

As a workaround I'd recommend using the Blink backend, with the added advantage that you get a new window that you can put in a separate monitor.

e.g.

using Blink: Window, body!
using Interact: @manipulate
using Plots: plot, plotlyjs
##

plotlyjs()
w = Window()
##

x = range(0, 6π; length=1000)
ui = @manipulate for i in 1:10
  plot(sin.(i .* x) .* cos.(i .* 2x))
end

body!(w, ui)
