2021-06-25 16:17:18 <thyriaen> howdy, i would like to concatinate 2 lists together - what kind of function do i use for this ? concat takes a list of lists
2021-06-25 16:17:46 <adamCS> thyriaen: ++
2021-06-25 16:18:10 <thyriaen> thanks
2021-06-25 16:20:27 <adamCS> thyriaen: You could also use <> which is monoidal append, which for lists is concatenation. That would continue to work if you switched from lists to, e.g., Seq or DList or some such.
2021-06-25 16:20:47 × warnz quits (~warnz@2600:1700:77c0:5610:350e:4738:7a75:35e) (Remote host closed the connection)
2021-06-25 16:21:39 <thyriaen> i am wondering if i can get something similiar to http://zvon.org/ locally for haskell like man pages for times without internet connections - is there such a thing ?
2021-06-25 16:22:21 <thyriaen> adamCS, is there a monoidal foldr/foldl too ?
2021-06-25 16:22:39 <adamCS> thyriaen: There is a way to set up a local "hoogle"
2021-06-25 16:23:15 <adamCS> yes. fold and foldMap
2021-06-25 16:23:30 <adamCS> https://hackage.haskell.org/package/base-4.15.0.0/docs/Data-Foldable.html#v:foldMap
2021-06-25 16:23:59 × dunkeln_ quits (~dunkeln@188.71.193.140) (Ping timeout: 250 seconds)
2021-06-25 16:24:44 <thyriaen> adamCS, ah nice, "normal" fold must have slipped my search
2021-06-25 16:25:20 <adamCS> thyriaen: Are you using stack? Apparently has a local hoogle feature.
2021-06-25 16:25:45 <adamCS> I think there's a nix way to set that up as well.
2021-06-25 16:25:50 <thyriaen> adamCS, what is stack ? fold is not found in Prelude
2021-06-25 16:26:13 <adamCS> You might need to import "Data.Foldable"
2021-06-25 16:27:49 × ubert quits (~Thunderbi@2a02:8109:9880:303c:ca5b:76ff:fe29:f233) (Remote host closed the connection)
2021-06-25 16:27:51 <adamCS> stack is an alternative to "cabal the tool" as the user front-end to managing dependencies, in the stack case via internally consistent snapshots of most packages.
2021-06-25 16:28:14 × stevenxl quits (~stevenlei@174.128.179.106) (Ping timeout: 244 seconds)
2021-06-25 16:28:22 <Franciman> stack is not simply an alternative to cabal the tool, its UI is quite different
2021-06-25 16:29:13 <adamCS> Franciman: Sure. I was trying for a minimal answer, given the context.
2021-06-25 16:29:48 <adamCS> thyriaen: https://hackage.haskell.org/package/bhoogle might be helpful on the local hoogle front.
2021-06-25 16:29:50 → stevenxl joins (~stevenlei@174.128.179.103)

2021-06-25 16:55:54 <qrpnxz> stack is like cabal's cabal, kind of a clusterfuck tbh
2021-06-25 16:57:41 × nschoe quits (~quassel@2a01:e0a:8e:a190:681:f80c:a16c:65d7) (Ping timeout: 244 seconds)
2021-06-25 16:57:58 <Clint> cabal's cabal, you say
2021-06-25 16:58:07 <qrpnxz> yes
2021-06-25 16:58:58 <qrpnxz> Or maybe like a harness to cabal. Or actually kind of like apt is to dpkg, except if dpkg already did pretty much everything apt did
2021-06-25 16:59:19 <sclv> lmao these metaphors are not helpful
2021-06-25 16:59:45 × zmt00 quits (~zmt00@user/zmt00) (Quit: Gone.)
2021-06-25 16:59:51 <qrpnxz> stack is indeed nonsense, nothing i can do about that
2021-06-25 17:01:05 <nitrix> Isn't cabal v2, cabal's cabal? And what about: cabal new-install Cabal cabal-install?
2021-06-25 17:01:25 <qrpnxz> cabal v2 is just cabal v2 afaik
2021-06-25 17:03:04 × MorrowM quits (~MorrowM_@147.161.13.193) (Ping timeout: 272 seconds)
2021-06-25 17:03:37 <sclv> anyway to run a local hoogle the best thing one can do is clone the current state of hoogle, then look at its auto-update script (https://github.com/ndmitchell/hoogle/blob/master/misc/Upgrade.hs) to try to understand how it fetches db info (its a bit underdocumented) and then use the cmd line exe directly
2021-06-25 17:04:46 <Las[m]> can someone explain to me why `fromIntegral (maxBound :: Int) :: CInt` is equal to -1?
2021-06-25 17:06:00 × tromp quits (~textual@dhcp-077-249-230-040.chello.nl) (Quit: My iMac has gone to sleep. ZZZzzz…)

2021-06-25 17:07:54 <qrpnxz> also on my terminal `fromIntegral (minBound :: Int)` prints 2^63-1 when the max for Int should be 2^29-1, weird

2021-06-25 17:09:01 <Las[m]> Even though it's 64 bits wide?
2021-06-25 17:09:24 <qrpnxz> what is
2021-06-25 17:09:38 <qrpnxz> Int has 23 bit range according to https://hackage.haskell.org/package/base-4.15.0.0/docs/Data-Int.html#t:Int
2021-06-25 17:09:45 <davean> qrpnxz: no, no
