Start Julia / Stop Julia fails sometimes in the newer versions

[aminya]

In the recent versions of Julia Client, the Restart Julia Client command fails in Juno-Plus. I am not sure if this is related to Julia-Client, but I didn't have this issue before, so I want to know if anything has changed regarding Start Julia, Stop Julia commands.

I'm having the same issue. If I want to restart the REPL, I have to restart Atom. Very frustrating.

We're looking into this, but it's fairly hard to figure out what's going on since the crash doesn't show a stacktrace (or an error, for that matter).

This. The exact same happens to me. I am using the latest Atom, Juno and Julia. I used to face this issue occasionally (which in itself was frustrating) but in the past few days (after the update I guess) this got worse and I have to manually close and open Atom to restart REPL. I get the error "Can't interrupt Julia without a Julia client running. Start a client with Packages -> Juno -> Start Julia." and when I try to start nothing happens. The minibar at the bottom left gets stuck on "working" mode too

For now, if during the crash Atom is still functional, you can use Ctrl+P + Reload to reload Atom without opening and closing.

@aminya Thanks for the tip but it doesn't work for me. Ctrl + P opens a window with some random files from my pwd I guess. Also, is there any other way to clear workspace besides stop and restart?

Sorry Ctrl+Shift+P that opens the command window.

For development, you can use Revise.jl. There is a Revise button in Juno-Plus: https://atom.io/packages/juno-plus (You should add Revise first)

Well, for this juno-plus case, the code that needs to be modified is not in julia-client, but in juno-plus.
I remember I told @aminya how to "implement" Restart Julia command, but now the atom.dispatch command doesn't return a Promise anymore and that just causes this error.

You can see my current implementation here and this should work for your package as well (it's really ad-hoc, though).

Separate from that, there is certainly issues of crashes on killing->restarting Julia process within the latest releases. But I would like to open an separate issue for that at Juno.jl, since this issue is originally for the one within juno-plus.

Let me close this in favor of JunoLab/Juno.jl#510.
