i should use the makefile

native maple Dec 11, 2025, 1:00 AM

#

make DAY=10

feral valve Dec 11, 2025, 1:01 AM

#

native maple `make DAY=10`

same thing

#

not like the makefile does any linking

elle abandoned soon

native maple Dec 11, 2025, 1:02 AM

genuinely so confused..???

#

is your elle up to date??

feral valve Dec 11, 2025, 1:03 AM

#

native maple is your elle up to date??

yeah

native maple Dec 11, 2025, 1:03 AM

#

do ellec solution.le --ssa and send result

feral valve Dec 11, 2025, 1:04 AM

#

oh just had to do install-runtime instead of install-stdlib

native maple Dec 11, 2025, 1:04 AM

#

you can just call make to update everything at once

#

compiler, stdlib, runtime

feral valve Dec 11, 2025, 1:05 AM

#

I don't use the normal target build-dir so it breaks

native maple Dec 11, 2025, 1:05 AM

#

ah

feral valve Dec 11, 2025, 1:07 AM

#

native maple ah

also add stacktraces

native maple Dec 11, 2025, 1:08 AM

#

blehhh why is it broken

native maple Dec 11, 2025, 1:10 AM

#

feral valve also add stacktraces

need to figure out how to generate those at some point

#

ok im going to bed

#

ping me if you get it working ill see it in the morning

native maple Dec 11, 2025, 1:13 AM

it is 1:15am girl 😭

#

i have school tomorrow

feral valve Dec 11, 2025, 1:13 AM

smh

#

i'm doing aoc instead of studying for exams

#

its actually horrible

native maple Dec 11, 2025, 1:13 AM

#

LITERALLY ME

#

i have an exam on friday lol

feral valve Dec 11, 2025, 1:14 AM

#

native maple i have an exam on friday lol

eyy same

native maple Dec 11, 2025, 1:14 AM

#

prepared? ❌

#

well kinda

#

ill just study tomorrow

feral valve Dec 11, 2025, 1:14 AM

#

I'm kinda cooked

native maple Dec 11, 2025, 1:14 AM

#

im glad i finished day 10 in a reasonable amount of time (it literally took all day)

feral valve Dec 11, 2025, 1:15 AM

#

yeah I told myself I was only gonna solve p1 today

#

i looked at it last night and already knew p2 was gonna be hell

native maple Dec 11, 2025, 1:15 AM

#

#

<1s still doable (thank fuck)

robust yacht Dec 11, 2025, 1:15 AM

#

native maple i have school tomorrow

erm actually the day has already passed so the correct statement would be "I have school today"

feral valve Dec 11, 2025, 1:43 AM

#

@native maple if the input is 166 lines long it breaks (gets that out of bounds err). If it is 165 or 167 lines long it works

#

haha

#

one of the strangest errors I've ever seen

feral valve Dec 11, 2025, 2:01 AM

#

of course, since it works with 167 lines, this is the fix

-    lines := io::read_to_string(args[1]).split("\n");
+    lines := io::read_to_string(args[1]).concat("[.] (0) {0}").split("\n");

#

is this cursed or what

#

of course, this has something to do with memory because a 166 line file filled with [.] (0) {0} will compute without fail

robust yacht Dec 11, 2025, 2:10 AM

167...

yes

isn’t the space switching slow then?

not really?

i use gestures

to switch

#

just the stock swipe gestures

when you switch spaces with hotkeys, there is still this animation. if SIP is disabled this can be removed

native maple Dec 11, 2025, 7:07 PM

well tbf i kinda dont wanna remove it lol

#

i like the animation

feral valve Dec 11, 2025, 7:07 PM

#

it’s still there if you swipe though

native maple Dec 11, 2025, 7:08 PM

#

i never use hotkeys anyway so that wouldnt affect me much

#

its certainly much better than a non-tiling wm tho

#

i dont have to fiddle around for ages to open 2 things side by side

#

or i guess before i used to just put them on different desktops and switch between them

#

but thats still bad

feral valve Dec 11, 2025, 7:09 PM

i’m on a non tiling wm and it’s actually more convenient for me, most important thing is spaces and hotkeys

@terse edge have you ever heard of a https://en.wikipedia.org/wiki/Finger_tree
