Stardust XR•3y ago

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

ls

ls

into kitty spawned in sway, it will run

ls

ls

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

Mmatthewcroughan And if I press Ctrl + C in Stardust, it'll kill stardust instead of killing the ...

Nova•6/21/23, 5:24 AM

that however is weird

matthewcroughanOP•6/21/23, 5:25 AM

If I hold onto the process without backgrounding it, the CTRL + C can't propagate to the program

matthewcroughanOP•6/21/23, 5:25 AM

If I background it, the shell executes my input

Nova•6/21/23, 5:25 AM

so if it's in the background ctrl+c... stops it?

matthewcroughanOP•6/21/23, 5:27 AM

opposite way around

matthewcroughanOP•6/21/23, 5:27 AM

I'm just describing that there are two cases, and both are bad

Nova•6/21/23, 5:27 AM

oh that makes perfect sense then

Nova•6/21/23, 5:28 AM

wait no it doesn't

Nova•6/21/23, 5:28 AM

if the process isn't backgrounded... why is it executing your input??

Nova•6/21/23, 5:28 AM

that makes no sense

matthewcroughanOP•6/21/23, 5:28 AM

That's not what I mean

matthewcroughanOP•6/21/23, 5:28 AM

I'll try to be clearer

matthewcroughanOP•6/21/23, 5:28 AM

If I fork it like then will execute my input

matthewcroughanOP•6/21/23, 5:29 AM

If I do not fork it like then will not execute my input, but signals are accepted from stdin by stardust-xr-server, such as CTRL + C, meaning the process will be killed, when what I really want to do is give that to

Nova•6/21/23, 5:29 AM

what do you mean by ==

matthewcroughanOP•6/21/23, 5:29 AM

that's what happens

Mmatthewcroughan If I do not fork it like `stardust-xr-server` then `bash` will not execute my i...

Nova•6/21/23, 5:30 AM

ohhhhhhhhhh i see the problem haha

Nova•6/21/23, 5:30 AM

it's not stdin

matthewcroughanOP•6/21/23, 5:30 AM

In sway, when I press it gets sent to kitty, which then sends it to bash

Nova•6/21/23, 5:30 AM

signals are controlled by the shell

matthewcroughanOP•6/21/23, 5:30 AM

in stardust launched from tty, when I press ^C, it gets sent to bash which then kills stardust

Nova•6/21/23, 5:31 AM

ctrl+c is intercepted by the shell

matthewcroughanOP•6/21/23, 5:31 AM

yeah

Nova•6/21/23, 5:31 AM

so we just need to figure out why sway doesn't have that

Nova•6/21/23, 5:31 AM

how can you quit sway from tty btw?

matthewcroughanOP•6/21/23, 5:31 AM

you don't and can't

matthewcroughanOP•6/21/23, 5:31 AM

you just launch it, and you have to either say from somewhere else on the system, or

Nova•6/21/23, 5:31 AM

well then... hmm

matthewcroughanOP•6/21/23, 5:32 AM

same with plasmashell

Nova•6/21/23, 5:32 AM

i know how that's done

Nova•6/21/23, 5:32 AM

it's done by intercepting all signals and ignoring them

Nova•6/21/23, 5:32 AM

but when stardust is launched from a regular terminal...

matthewcroughanOP•6/21/23, 5:32 AM

traps they're called in normal shell lingo

Nova•6/21/23, 5:32 AM

right yea

Nova•6/21/23, 5:33 AM

i guess i could make a flag for it

Nova•6/21/23, 5:33 AM

but what should the default be
