Stardust needs to swallow all input, even when forked

otherwise it's duplicated

Mmatthewcroughan Stardust needs to swallow all input, even when forked

Nova•6/21/23, 4:59 AM

idk how to get stardust to not take in input on the command line, i know how to do it for the processes it spawns though

matthewcroughanOP•6/21/23, 5:00 AM

hmm.. could work

matthewcroughanOP•6/21/23, 5:00 AM

the way I'm thinking about it is that you would launch which then auto launches the rest of the programs

matthewcroughanOP•6/21/23, 5:00 AM

via the config file

matthewcroughanOP•6/21/23, 5:01 AM

stardust-xr-server should then therefore swallow all input and not allow any

matthewcroughanOP•6/21/23, 5:01 AM

then you don't need to modify the stdin of the spawned proceses, it's cut off in one location, the beginning, the entrypoint, the main

Nova•6/21/23, 5:01 AM

right, but idk how to do that

matthewcroughanOP•6/21/23, 5:01 AM

It's the correct way to do it, so let's try

Nova•6/21/23, 5:01 AM

i can read from stdin

matthewcroughanOP•6/21/23, 5:01 AM

I'll look into some of the rust code

Nova•6/21/23, 5:01 AM

but idk how to redirect it to nothing

matthewcroughanOP•6/21/23, 5:02 AM

/dev/null

Mmatthewcroughan I'll look into some of the rust code

Nova•6/21/23, 5:02 AM

you won't find anything in stardust itself, but def if there's any docs...

Mmatthewcroughan /dev/null

Nova•6/21/23, 5:02 AM

well yea, but doing that in the program :p

what is this doing?

matthewcroughanOP•6/21/23, 5:03 AM

Maybe the stardust-server could swallow stdinput only if is spawned

matthewcroughanOP•6/21/23, 5:03 AM

you could have stardust clients that tell the server to swallow stdin

matthewcroughanOP•6/21/23, 5:03 AM

the server will swallow stdin if an input client is spawned

matthewcroughanOP•6/21/23, 5:04 AM

like wayland protocol extensions or something, features/capabilities

Mmatthewcroughan you could have stardust clients that tell the server to swallow stdin

Nova•6/21/23, 5:04 AM

no it always should

Nova•6/21/23, 5:04 AM

i just don't know how

Mmatthewcroughan what is this doing?

Nova•6/21/23, 5:05 AM

that's for spatial input

Nova•6/21/23, 5:05 AM

input methods/handlers

matthewcroughanOP•6/21/23, 5:06 AM

if you do it for eclipse, I can go to the tty where eclipse is running and provide my input there

matthewcroughanOP•6/21/23, 5:06 AM

when stardust is run in the other context of auto spawning the programs, this will fail of course

Mmatthewcroughan if you do it for eclipse, I can go to the tty where eclipse is running and provi...

Nova•6/21/23, 5:06 AM

yes but how

matthewcroughanOP•6/21/23, 5:07 AM

Asking chatgpt

Nova•6/21/23, 5:08 AM

haha cool

matthewcroughanOP•6/21/23, 5:09 AM

matthewcroughanOP•6/21/23, 5:09 AM

It misunderstood the context, it thinks our rust program is running stardust-xr-server, but it does give some hints

here we go

Nova•6/21/23, 5:10 AM

can you get the context properly understood?

matthewcroughanOP•6/21/23, 5:10 AM

the final message

matthewcroughanOP•6/21/23, 5:10 AM

yeah it understood it now

matthewcroughanOP•6/21/23, 5:11 AM

you can detach stdin and or redirect it to /dev/null

matthewcroughanOP•6/21/23, 5:11 AM

in the main function of the program

Nova•6/21/23, 5:14 AM

can you explain it to me?

matthewcroughanOP•6/21/23, 5:16 AM

maybe it'd make sense if I made an example in bash

matthewcroughanOP•6/21/23, 5:17 AM

since this is really all related to the shell

matthewcroughanOP•6/21/23, 5:17 AM

matthewcroughanOP•6/21/23, 5:17 AM

oh, maybe I can do it with without stardust then?

Mmatthewcroughan you can detach stdin and or redirect it to /dev/null

Nova•6/21/23, 5:20 AM

wait remind me why we're doing this?

Nova•6/21/23, 5:20 AM

why does it matter if i type things in stardust and they show up in the terminal?

NNova why does it matter if i type things in stardust and they show up in the terminal...

matthewcroughanOP•6/21/23, 5:22 AM

Because if I type into kitty spawned in sway, it will run twice

matthewcroughanOP•6/21/23, 5:22 AM

Once in kitty in sway, and secondly in the TTY where I spawned everything

matthewcroughanOP•6/21/23, 5:23 AM

And if I press Ctrl + C in Stardust, it'll kill stardust instead of killing the program I've spawned from kitty

Mmatthewcroughan Once in kitty in sway, and secondly in the TTY where I spawned everything

Nova•6/21/23, 5:23 AM

ah, that's what happens when it's in the background
