2024-11-01 10:27:16 +0100 <tomsmeding> my experience with this stuff is that IO seems to be strict in all your tests, but it fails if you actually want to use that for code correctness
2024-11-01 10:27:19 +0100 <tomsmeding> so use evaluate and be safe
2024-11-01 10:34:05 +0100 <c_wraith> evaluate isn't magic. the documentation explains what does and why.
2024-11-01 10:35:43 +0100 <tomsmeding> right. In practice, though, not using `evaluate` comes to bite me not in the presence of exceptions but when benchmarking
2024-11-01 10:36:10 +0100 <tomsmeding> if you want to benchmark an IO operation and are doing the timing manually for some reason, please, use `evaluate`. Using `return $! _` or something similar _will not work properly_
2024-11-01 10:36:15 +0100 <tomsmeding> it will work sometimes

2024-11-01 11:25:38 +0100 <tomsmeding> you can create the binding locally
2024-11-01 11:25:46 +0100 <tomsmeding> `let ?param = _ in f x y z`

2024-11-01 12:15:35 +0100 <sprotte24> I want to write a Haskell program
2024-11-01 12:15:47 +0100 <sprotte24> Hi, Rembane
2024-11-01 12:15:51 +0100 <mauke> what's it do?
2024-11-01 12:16:19 +0100 <Hecate> rembaaaaaaane
2024-11-01 12:16:25 +0100 <Hecate> what's uuuuup
2024-11-01 12:16:28 +0100 <sprotte24> The Haskell programm has to compute the nearest Power of two for a given n.
2024-11-01 12:16:34 +0100 <Hecate> sprotte24: nice
2024-11-01 12:16:37 +0100 <sprotte24> Example:
2024-11-01 12:16:42 +0100 <mauke> oh, is this homework?
2024-11-01 12:17:21 +0100 <sprotte24> n= 9 nearest Power is 16
2024-11-01 12:17:35 +0100 <mauke> I'd say it's 8
2024-11-01 12:17:41 +0100 <sprotte24> Yes. kome work
2024-11-01 12:18:03 +0100 <Hecate> mauke: maybe they have to round to the highest power of 2
2024-11-01 12:18:15 +0100 <mauke> yeah, that actually makes things easier
2024-11-01 12:18:22 +0100 <Rembane> Hecate: Suuuuuuuuuuuuuuuuuup! :D
2024-11-01 12:18:23 +0100 <sprotte24> The restriction: using binary is forbidden.
2024-11-01 12:18:33 +0100 <mauke> define "using binary"
2024-11-01 12:18:38 +0100 <mauke> like bit shifts?
2024-11-01 12:18:46 +0100 <Hecate> damnit I was about to suggest that hahahaha

2024-11-01 14:30:47 +0100 <merijn> mauke: Cabal just invokes GHC on C files, which determines what C compiler to call
2024-11-01 14:30:58 +0100 <merijn> I think there was either a config file or GHC flag to tell it to use something else

2024-11-01 14:32:01 +0100 <mauke> the fun part is that it only happens on 'cabal install'. 'cabal build' is fine with it
2024-11-01 14:32:09 +0100 <merijn> mauke: Ah, that sounds more like wrong include dirs than wrong compiler, no?
