Gustavo Goretkin (Mar 25 2021 at 18:08): Gustavo Goretkin (Mar 25 2021 at 18:08):I'm confused. In my startup.jl I have @show isinteractive()
julia --banner=no
isinteractive() = false
julia> isinteractive()
true
julia>
and if I start a REPL in VS Code
isinteractive() = true
julia> isinteractive()
true
I thought I didn't need to use atreplinit anymore, or something like that.
Expanding Man (Mar 25 2021 at 18:11):It must have something to do with how VS code starts the Julia process. It might even be considered a bug in the VS code plugin because as far as I know the startup.jl is deliberately supposed to take place before the REPL initializes
Expanding Man (Mar 25 2021 at 18:12):If I had to take a guess I would say that they are starting a "bare" Julia process, initializing the REPL, and then handling some other initialization on their own after that
Sebastian Pfitzner (Mar 25 2021 at 18:13):I mean the session is interactive in both cases
Gustavo Goretkin (Mar 25 2021 at 18:13):yeah, I expect the VS Code behavior honestly.
Gustavo Goretkin (Mar 25 2021 at 18:14):What is the right way to do what I intend?
Expanding Man (Mar 25 2021 at 18:15):My impression was that isinteractive() was supposed to be interpreted as "is this a running REPL?" rather than being a property of the run-time itself, though the documentation would seem to support your perspective
isinteractive() -> Bool
Determine whether Julia is running an interactive session.
I still seem to be using atreplinit(), my startup here
Gustavo Goretkin (Mar 25 2021 at 18:20):thanks @Expanding Man . I was under the misguided impression that atreplinit(f) was "oldschool", but I think that was just because Revise can now hook into it itself.
Expanding Man (Mar 25 2021 at 18:21):I do seem to recall someone saying that you shouldn't need atreplinit anymore, but at the moment it's not clear to me why that would be the case
Expanding Man (Mar 25 2021 at 18:22):At least Revise claims not to need it however it does not rely on isinteractive() in an obvious way, so it may be advice that can't be generalized to other startup stuff
Gustavo Goretkin (Mar 25 2021 at 18:29):@Sebastian Pfitzner do you believe the behavior with respect to isinteractive() in startup.jl should be consistent whether the REPL is run from my shell or from VS Code's terminal?
Sebastian Pfitzner (Mar 25 2021 at 18:30):yes
Gustavo Goretkin (Mar 25 2021 at 21:43):I think the difference just comes down to VS Code invoking julia with the -i flag
Gustavo Goretkin (Mar 25 2021 at 21:45):BTW I commenting on this related issue: https://github.com/JuliaLang/julia/issues/10779
Sebastian Pfitzner (Mar 26 2021 at 09:01):FWIW, we can't start Julia without -i because we also give a file to execute
