Re: [julia-users] Re: Hide and disable REPL

[cdm]

it seems like some of the client.jl code

   https://github.com/JuliaLang/julia/blob/master/base/client.jl


should provide the foundation ...


maybe something around active_repl_backend or some active_repl
switching.

also from code comments:

atreplinit(f)
Register a one-argument function to be called before the REPL interface is 
initialized in
interactive sessions; this is useful to customize the interface.

hopefully, helpful in the slightest ...

I think most of them just have the code pasted into the REPL. That would work 
for us as well, but then we can’t do things like eval code in the context of a 
specific module.

RE: [julia-users] Re: Hide and disable REPL

[David Anthoff]

That deletes everything, but really I just want to hide the current prompt. So 
say this is how the console looks:



julia> println(5)

5

julia>function foo(x)

   println(x)



So in this case the users is in the middle of entering something new into the 
REPL (i.e. the definition of foo). Assume that at this point my background task 
receives a message. I then want to be able to delete line 3+5, and position the 
cursor on column 1 line 3. Then I’ll execute the code that was sent to the 
server. Once that is finished, I want to print line 3+4, as it was before I hid 
the current prompt, again, starting at whatever the current cursor position is.

 

For example, say the background task received some code that printed “Foo” 
to the console, then I want the console to look like this, immediately after 
that code was executed:



julia> println(5)

5

Foo

julia>function foo(x)

   println(x)



I.e. the user could continue editing the stuff that he/she was working on 
before the background task briefly took over.

 

Thanks,

David

RE: [julia-users] Re: Hide and disable REPL

[David Anthoff]

Ah, I should have been clearer. I just want to hide the prompt temporarily.

 

The complete setup is slightly more complicated, but you can imagine just the 
following: start a normal julia REPL. Then include a file that will start a 
server listening on some socket. This server is all async, so as soon as the 
server is started, the prompt appears again and one can use this REPL window in 
the normal way. Now some other process connects to the socket, and sends some 
code that this server will eval. Before the server evals this code, I would 
like it to switch off the prompt, then eval the code, then switch the prompt on 
again.

 

The setup is that VS Code starts a new julia process, and shows the normal 
julia REPL in a terminal emulation within VS Code. This instance is running the 
server I just described. The julia VS Code extension that will send code to 
this REPL window if a user hits Ctrl+Enter in any of the open editor windows.

 

Not sure this is much clearer, let me know if you need more info!

 

Best,

David

Can you explain the setup further -- Where is the REPL running? How are you 
interacting with it? If I take "I want to temporarily switch the REPL off, i.e. 
it should visually disappear" literally then it seems like a strange thing to 
do, so I may be missing something

 

If you *do* want to hide the terminal window (if any) the REPL is (may be) 
running in, that's going to be very hard to do generally and across platforms 
(on Windows under Console you can use GetActiveWindow or GetActiveConsole, but 
on real pty platforms the process doesn't necessarily know anything about the 
terminal it is connected to beyond termcap and i/o).

Hi,

 

is there a way to switch off the REPL and then on again, from a task?

 

Specifically, I want to start a julia instance and pass a script in with the –L 
parameter that will open a socket, listen for connections and the process 
messages from that socket. This server listening code is all wrapped in @async 
macro calls. So when I start things this way, julia shows the REPL and at the 
same time listens for incoming messages. I can use the REPL etc. This is 
exactly what I want.

 

But when I receive a message, I want to temporarily switch the REPL off, i.e. 
it should visually disappear while I process that message, and then I want to 
switch it back on once I’m done processing that message.

 

Can that be done somehow?

 

Thanks,

David
