| 2024-06-26 01:00:46 +0200 | <safinaskar> | in haskell |
| 2024-06-26 01:00:57 +0200 | <safinaskar> | this means that induction actually works! |
| 2024-06-26 01:01:13 +0200 | <safinaskar> | so yes, i was able to cope with all problems! |
| 2024-06-26 01:01:52 +0200 | <safinaskar> | so, yes, it is possible to fake type-level lambdas! |
| 2024-06-26 01:03:21 +0200 | <EvanR> | for your next trick, use haskell to prove FALSE |
| 2024-06-26 01:04:09 +0200 | <safinaskar> | EvanR: unfortunately, this is easy, too. "false :: forall a. a" "false = undefined" |
| 2024-06-26 01:04:13 +0200 | waleee | (~waleee@h-176-10-144-38.NA.cust.bahnhof.se) |
| 2024-06-26 01:04:25 +0200 | <EvanR> | and see that it is much more powerful than stuff like coq which cripples itself into only proving true stuff |
| 2024-06-26 01:09:54 +0200 | <safinaskar> | how i will try to prove the same thing using C++ and Rust :) |
| 2024-06-26 01:10:22 +0200 | <safinaskar> | i'm not sure about Rust, but in C++ this seems to be totally possible |
| 2024-06-26 01:11:36 +0200 | <safinaskar> | for example, "f :: forall (a :: Type -> Type). Int" can be written in C++ so: "template <template <typename> typename T> int f()" |
| 2024-06-26 01:34:18 +0200 | <joeyadams> | Records compile into somewhat large binaries, is this a known issue? For example, I have a module with 16 records (205 fields), and it produces a 490K .o file (versus 99K if I remove the records). If I derive generic Aeson instances, it becomes 2.3M, and takes several seconds to compile. |
| 2024-06-26 01:35:44 +0200 | <joeyadams> | This means if I generate bindings for a database with 100 tables, I end up with an absurdly large binary. Not the end of the world, just slightly disappointing. |
| 2024-06-26 01:43:27 +0200 | <safinaskar> | joeyadams: use rust. it compiles fast (compared to haskell) |
| 2024-06-26 01:43:47 +0200 | <safinaskar> | joeyadams: aeson in rust world is called serde_json |
| 2024-06-26 01:44:14 +0200 | <safinaskar> | joeyadams: instances for serde_json are generated automatically, too |
| 2024-06-26 01:45:03 +0200 | <joeyadams> | Just curious, does serde_json use a generic system sort of like Haskell has, or is it more like C# where it's all run-time reflection? |
| 2024-06-26 01:45:06 +0200 | <safinaskar> | joeyadams: binary sizes likely to be big, too. but compilation speed will be nice |
| 2024-06-26 01:45:46 +0200 | <joeyadams> | So I just need to write a quick sed replace to turn my Haskell code into Rust, and I'll be set :-) |
| 2024-06-26 01:45:55 +0200 | <safinaskar> | joeyadams: serde_json works in compile-time |
| 2024-06-26 01:46:49 +0200 | <safinaskar> | joeyadams: first package called "serde" derives all needed instances in compile time using so-called proc macros (it is code, which executes in compile time and generates AST, similar to template haskell) |
| 2024-06-26 01:46:56 +0200 | <safinaskar> | and then serde_json uses these instances |
| 2024-06-26 01:48:19 +0200 | <joeyadams> | An important detail I left out: I had deriving Show on all my records. I took that off and that took off 300K. |
| 2024-06-26 01:51:23 +0200 | <joeyadams> | But I am curious why derived instances might take up so much code. Deriving FromJSON/ToJSON for 15 records produces as much binary code as the whole Aeson library. |
| 2024-06-26 01:51:39 +0200 | <EvanR> | Hi can you not respond to a haskell question by saying use rust |
| 2024-06-26 01:51:40 +0200 | <joeyadams> | I should try writing the instances manually to see how big the code footprint is. |
| 2024-06-26 01:52:06 +0200 | <safinaskar> | EvanR: okay :( |
| 2024-06-26 01:53:00 +0200 | <EvanR> | joeyadams, did you try flags to reduce the binary size, did you try to strip the binary |
| 2024-06-26 01:53:14 +0200 | <EvanR> | are you compiling in profiling support |
| 2024-06-26 01:54:20 +0200 | <joeyadams> | I'm just using GHC 9.4.8 installed through ghcup, not sure what that compiled in. I also tried with later GHC versions and saw similar results (slow compiles and large binaries). |
| 2024-06-26 01:55:08 +0200 | <EvanR> | template haskell and generics does have a compile time cost, but you were asking about binary size |
| 2024-06-26 01:55:27 +0200 | <EvanR> | you can issue flags to optimize for speed or size... -Os ? |
| 2024-06-26 01:56:06 +0200 | <joeyadams> | I looked into some flags a while back, it didn't help much. My results are with -O1. If I use ghc -O0 it makes the binary even bigger. |
| 2024-06-26 01:56:16 +0200 | <EvanR> | what about -O2 |
| 2024-06-26 01:56:51 +0200 | <EvanR> | also you can try to strip the binary after the fact |
| 2024-06-26 01:57:41 +0200 | <joeyadams> | Same size with -O2. Does GHC have something like -Os ? |
| 2024-06-26 01:57:50 +0200 | <EvanR> | -Os |
| 2024-06-26 01:58:31 +0200 | <EvanR> | guess not... |
| 2024-06-26 01:58:52 +0200 | <joeyadams> | strip takes the program from 24M to 14M, and the .o file from 2.3M to 1.2M. Better, but still a lot. |
| 2024-06-26 01:59:55 +0200 | <joeyadams> | (the "program" is just a single .hs file where I copied some of my records over and pruned them. It references aeson, uuid-types, scientific, text, and bytestring. |
| 2024-06-26 02:00:47 +0200 | <EvanR> | there might be some more you could try https://stackoverflow.com/questions/6115459/small-haskell-program-compiled-with-ghc-into-huge-bina… |
| 2024-06-26 02:04:54 +0200 | <joeyadams> | Thanks. Maybe I should just create a single record and derive FromJSON, and look at the assembly. I'm mainly curious why it takes so much code to do (what should be) so little. |

| 2024-06-26 21:26:50 +0200 | <kqr> | Hello all! I am making some experiments in Haskell after about a 7 year hiatus from it, and I have one confusion I don't remember having before. I'm intending to use the `assign` function from Control.Lens, so I wanted to check what sort of state type to use. I clicked the MonadState constraint in the Haddocks and ended up in the adjunctions package which defines a State type. So far, so good. |
| 2024-06-26 21:26:53 +0200 | <kqr> | however, when I want to evalState this State type, it expects me to pass a `Rep g` as the initial input, and I just don't understand what this Representable thing is! Am I going about something backwards? |

| 2024-06-26 21:29:00 +0200 | <haskellbridge> | <iqubic (she/her)> You want this, from MTL: https://hackage.haskell.org/package/mtl-2.3.1/docs/Control-Monad-State-Class.html#t:MonadState |
| 2024-06-26 21:29:24 +0200 | <ncf> | it seems like lens uses its own MonadState from adjunctions, but you can (and should probably) use it with the StateT from transformers/mtl |
| 2024-06-26 21:29:47 +0200 | <energizer> | defining a function `cartesianProduct xs ys` is there a convention about defining it in terms of recursion on the left or right argument? ie `cartesianProduct _ [] = []` or `cartesianProduct [] _ = []` which is preferred, or does it depend on something? |
| 2024-06-26 21:30:44 +0200 | <kqr> | ncf, That sounds more like what I remember! Thanks! How can all these State implementations/interfaces be compatible? |
| 2024-06-26 21:31:18 +0200 | <haskellbridge> | <sm> energizer: I think the rule of thumb is something like, most changeable arguments to the right, to make partial application more convenient |
| 2024-06-26 21:31:26 +0200 | <ncf> | there is simply a adjunctions.MonadState instance for transformers.StateT |
| 2024-06-26 21:31:50 +0200 | <energizer> | sm in this case the arguments are symmetric, the only difference is left/right |
| 2024-06-26 21:31:55 +0200 | <ncf> | energizer: it doesn't really matter as long as you document it, but i would expect that to behave as liftA2 (,) |
| 2024-06-26 21:31:58 +0200 | <jackdk> | kqr: adjunctions re-exports `MonadState` from mtl, so it's the one you know and remember. It's providing its own monad with an instance. |
| 2024-06-26 21:32:06 +0200 | <ncf> | > liftA2 (,) [1,2] [3,4] |
| 2024-06-26 21:32:08 +0200 | <lambdabot> | [(1,3),(1,4),(2,3),(2,4)] |
| 2024-06-26 21:32:10 +0200 | <kqr> | ncf, Oh, yes, of course. It was a few years ago, as I said. Thank you again! |
| 2024-06-26 21:32:26 +0200 | <mauke> | energizer: I'd expect recursion on the first argument |
| 2024-06-26 21:38:40 +0200 | <energizer> | mauke: can you say why? |

| 2024-06-26 21:42:10 +0200 | <energizer> | that recurses on both arguments because it has to |
| 2024-06-26 21:44:59 +0200 | <mauke> | yes, but it starts by checking the first argument first |

| 2024-06-26 21:53:09 +0200 | <haskellbridge> | <iqubic (she/her)> I guess for reasons of like, "it's so easy to do partial application in Haskell", you might want to check the first argument first, and short-circuit if needed. That prevents you from needing to write "flip f" in cases where that's equivalent, just for the extra performance boost. |

It's not just `cartesianProduct (flip f) (y:ys) xs` because that puts the result in the wrong order. Is there a nice way to express the result? |
