Brendan Hansknecht (Oct 09 2022 at 00:12): Brendan Hansknecht (Oct 09 2022 at 00:12):Just did day 10. Actually used a tag for once. Overall was quite straightforward: https://github.com/bhansconnect/roc-aoc-2021/blob/trunk/day10/part2.roc
In the last 2 problems, I defined a crash helper for simplicity. probably could be written better:
crash : a -> a
crash = \a -> crashInternal (0 - 1) a
crashInternal : U8, a -> a
crashInternal = \_, a -> a
Also, I feel the more pipelining I do, the less backpassing I do. I guess it is backpassing for tasks and pipelining for data manipulation.
Ayaz Hafiz (Oct 09 2022 at 00:15):you could make crash simpler as just
crash : {} -> a
and leave the body unimplemented
Richard Feldman (Oct 09 2022 at 00:18):or if you want a body (for some reason):
crash : {} -> *
crash = \{} -> if 0u8 - 1 > 0 then crash {} else crash {}
Without a body wouldn't roc check fail?
Brendan Hansknecht (Oct 09 2022 at 01:55):And roc dev
Ayaz Hafiz (Oct 09 2022 at 01:59):no
Brendan Hansknecht (Oct 09 2022 at 02:10):I am very confused... Why is an undefined function with only a prototype not a warning?
Brian Carroll (Oct 09 2022 at 15:45):I believe the idea is to let you sketch out a design for a program and get parts of it working. The undefined function bodies get replaced with roc_panic I think
Richard Feldman (Oct 09 2022 at 16:42):yeah, although we should probably give a reminder somehow
Richard Feldman (Oct 09 2022 at 16:42):maybe a little note at the end like: "these functions don't have implementations yet: Foo.bar, Baz.blah, ..."
Brendan Hansknecht (Oct 09 2022 at 16:52):sure, but roc check is supposed to fail CI on warnings or errors. I think not defining a function is something worth failing CI over.
Brian Carroll (Oct 09 2022 at 16:55):Good point!

An easy one (or I'm better than before :sweat_smile:)
Looks like challenge motivation has been lost, I will probably continue without notify. It has been very entertaining and instructive to do it, lot of progress done. My brain is now directly thinking in Roc instead of Go or JS. Looking forward for easier debug and editor type help for AoC 2022 :innocent:
Brendan Hansknecht (Oct 22 2022 at 22:18):Yeah, we are apparently like regular advent if code people. Day ten is a far way to make it.
Anton (Oct 23 2022 at 07:52):Looking forward for easier debug and editor type help for AoC 2022 :innocent:
editor type help will unfortunately not be ready for AoC 2022, we had this working for small programs but we have a big rewrite planned of an important part of the editor. So it does not make sense to try to expand type help before that because we'd have to throw a lot of it out.
