| 2022-07-31 11:06:43 +0200 | <ggVGc> | tomsmeding: thanks, was trying to achieve it through a type family (like you showed) but got stuck a few times. Your example helps a lot! |
| 2022-07-31 11:07:19 +0200 | <ggVGc> | blunt hammer is fine for my use-case. I have the exact same "blunt hammer" implemented at the value level atm... |
| 2022-07-31 11:08:18 +0200 | <ggVGc> | it validates subsets of ranges. Like, positive numbers being a subset of all numbers, and nullable ranges not being subsets of non-nullable ones etc. |
| 2022-07-31 11:08:39 +0200 | <tomsmeding> | Sounds like a lattice |
| 2022-07-31 11:08:46 +0200 | <ggVGc> | I've been meaning to move most of it to the type level for a long time but never got to it (and haven't been sure how to best achieve it) |
| 2022-07-31 11:08:58 +0200 | <tomsmeding> | Though I doubt knowing that it's a lattice helps much :) |

| 2022-07-31 11:11:06 +0200 | <tomsmeding> | Doing it with a closed type family instead of a network of type class instances (if that's even possible -- definitely with overlapping instances, but eh) furthermore has the advantage that a malicious user can't just add an extra instance |
| 2022-07-31 11:13:54 +0200 | <ggVGc> | yep, that's why I felt type families might be the right choice. I went down the type class path a bit, and it didn't feel like it'd work out well |
| 2022-07-31 11:14:36 +0200 | <ggVGc> | this is my first actual usage of type families though, so it's good to finally understand them through a real-world use-case |

| 2022-07-31 11:19:02 +0200 | <ggVGc> | Guest49: your age probably doesn't matter much, but your past programming experience does. Haskell the language is somewhat okay as a first choice, although learning it from online resources is more challenging than other languages in my opinion. The bigger issue I think, for a beginner in programming in general, is that the tooling around haskell is still less than ideal, and it can be hard to |

| 2022-07-31 11:25:18 +0200 | <Guest49> | Do you think that learning a functional program first is a good idea at all? |
| 2022-07-31 11:26:20 +0200 | <ggVGc> | My personal input is that I was programming for a few years in C++, C# and Python, and at age 19 (not that age matters that much) I had my first go at Haskell. I didn't have a great time, and eventually gave up and started writing F# instead (which had just been released that year). A few years after that I started looking at haskell again and am using it today. But I don't think that the |
| 2022-07-31 11:26:22 +0200 | <ggVGc> | developer experience of Haskell is |
| 2022-07-31 11:26:31 +0200 | <ggVGc> | very good compared to other languages, even if I like the language itself now |
| 2022-07-31 11:26:49 +0200 | <ggVGc> | Guest49: yes, definitely going the functinal path from the start is a good idea |
| 2022-07-31 11:26:55 +0200 | <ggVGc> | that's why I think Elixir is a great stepping stone |
| 2022-07-31 11:27:45 +0200 | <ggVGc> | It's a well designed, easy-to-use, functional programming language that is used in production by many companies (e.g it's mature, both in functionality and tooling) |
| 2022-07-31 11:28:05 +0200 | <Rembane> | A lot of time and effort has gone into the developer experience of elixir. |
| 2022-07-31 11:28:15 +0200 | <ggVGc> | it's definitely not as powerful as Haskell, but as a beginner (either in programming, or functional programming) that's mostly a good thing |

| 2022-07-31 11:30:44 +0200 | <ggVGc> | Guest49: Haskell is a very interesting language to learn, and it has capabilities that are difficult to find elsewhere. But, that comes at a (sometimes huge) learning cost, and most of it is actually not really useful for the vast majority of things. So, my personal suggestion is to say "Haskell is interesting, I'll definitely look at it" but not as a first step, or even in the first years of |

| 2022-07-31 11:37:48 +0200 | <ggVGc> | Guest49: I would say this. Pick some choices, e.g Haskell, Elixir, maybe Go, or Python. Spend a few days with each of them and try to do something simple (like getting the initial environment up and writing a small program). Compare the experience of how comfortable the experience is, and how easy it is to find clear information. Then pick one |
| 2022-07-31 11:38:13 +0200 | <ggVGc> | I think that's the most important thing in the beginning, being able to find good information (that you understand) and easily working with the language |
| 2022-07-31 11:38:18 +0200 | <ggVGc> | not necessarily what language you use |
| 2022-07-31 11:38:29 +0200 | <tomsmeding> | ggVGc++ |
| 2022-07-31 11:38:45 +0200 | <ggVGc> | after a few months you'll be able to switch to some other language and have an easier time |
| 2022-07-31 11:39:19 +0200 | <tomsmeding> | Trying multiple languages initially takes some time investment without much reward yet, though |

| 2022-07-31 11:39:50 +0200 | <ggVGc> | tomsmeding: yeah, but if you spend a day and can't get the initial workflow up, then maybe at least that one isn't a good choice |

| 2022-07-31 11:42:24 +0200 | <ggVGc> | tomsmeding: I honestly think, unfortunately, that what makes Haskell unsuitable for selfstufy as a beinnger is the same reason that it is what it is (a platform for language research). It's so wide, and so evolving, and people often come to it with significant background experience (but everyone from different pasts). So, the information you find when trying to learn something is often fragmented, |
| 2022-07-31 11:42:26 +0200 | <ggVGc> | hard to grasp, unclear if it is actually what you're looking for or not etc. |
| 2022-07-31 11:42:32 +0200 | <ggVGc> | no one sat down and wrote a propoer "Getting started" |
| 2022-07-31 11:42:42 +0200 | <ggVGc> | and library documentation is atrocious |
| 2022-07-31 11:43:12 +0200 | <tomsmeding> | ggVGc: I kind of agree :) |
| 2022-07-31 11:43:22 +0200 | <ggVGc> | restricting to Haskell2010 definitely is better as a start, I think. But that doesn't help the issue of learning resources, which are not carrying that restriction |
| 2022-07-31 11:43:29 +0200 | <tomsmeding> | Yeah |
| 2022-07-31 11:44:39 +0200 | <ggVGc> | This is why I suggest Elixir (not because that's what I did for work lately). The whole community very much values clear documentation, avoids complexities as much as it can, and just tries to keep things simple and well-described |
| 2022-07-31 11:44:47 +0200 | <ggVGc> | it makes for a very good grounds for learning |
| 2022-07-31 11:45:03 +0200 | <tomsmeding> | "avoids complexities as much as it can" -- right |
| 2022-07-31 11:45:26 +0200 | <tomsmeding> | So the language is less expressive than haskell, and they embrace that |
| 2022-07-31 11:45:48 +0200 | <ggVGc> | I brought a frontend developer at work into our backend team in 2-3 months, in which he got comfortable with proper functional programming (not JS-"functional") and unit testing (which he never really did properly before) |
| 2022-07-31 11:45:52 +0200 | <ggVGc> | and backend development in general |
| 2022-07-31 11:45:55 +0200 | <tomsmeding> | That's a good thing and very nice until you need the extra functionality |
| 2022-07-31 11:46:07 +0200 | <ggVGc> | yeah, but 99% of the time you don't |
| 2022-07-31 11:46:21 +0200 | <tomsmeding> | But then I believe that a good programmer should know >1 language in the first place :) |

| 2022-07-31 11:47:19 +0200 | <tomsmeding> | That's certainly a vote of confidence for elixir |

| 2022-07-31 11:55:00 +0200 | <ggVGc> | yep |
| 2022-07-31 11:55:20 +0200 | <tomsmeding> | How would you express \f x _ -> f x 123 |
| 2022-07-31 11:55:33 +0200 | <ggVGc> | but, in general things are a lot less automatic, which again I think is a good thing for beginner programming, and honestly for long-term maintenance of production code also |
| 2022-07-31 11:55:37 +0200 | <tomsmeding> | Not &(&1, 123) because that is \f x -> f x 123 :p |
| 2022-07-31 11:57:00 +0200 | <tomsmeding> | I have mixed feelins about not having automatic currying -- I'm quite sure that it's easier to learn and that knowledge transfers more easily between elixir and most other languages. But on the other hand, power users at some point want power tools |
| 2022-07-31 11:57:44 +0200 | <tomsmeding> | Terse syntax is bad for its learning curve and intelligibility for non-experts, but experts benefit from terse syntax |

| 2022-07-31 11:59:34 +0200 | <tomsmeding> | From just what you've told me, though (which is all I know about elixir :p), I do agree with your recommendation of it over haskell as a first language |
| 2022-07-31 12:00:17 +0200 | <tomsmeding> | Not quite convinced yet it should necessarily be one's first _functional_ language if one already has a bunch of programming experience |
| 2022-07-31 12:02:07 +0200 | <tomsmeding> | Jade30: curious, is haskell your first programming language? Most other things would not work either without base-devel, I think :p |
| 2022-07-31 12:02:35 +0200 | <tomsmeding> | Perhaps the scripting languages might (js, python) |

| 2022-07-31 12:02:50 +0200 | <Jade30> | No, idk how many languages I know. I just reinstalled arch and forgot `base-devel` |
| 2022-07-31 12:02:59 +0200 | <tomsmeding> | Ah that also explains :) |
| 2022-07-31 12:03:22 +0200 | <tomsmeding> | Yay arch btw |
| 2022-07-31 12:03:36 +0200 | <Jade30> | I do that more often than I should, but a package list and a seperate home partition make it easy |
| 2022-07-31 12:03:46 +0200 | <tomsmeding> | And good on you for using ghcup instead of the ghc package from the arch repos :p |

| 2022-07-31 12:06:14 +0200 | <Jade30> | Now I still don't have ghcup working .. I think my failed install mesed with some caches. |
| 2022-07-31 12:06:14 +0200 | <Jade30> | The only thing it installed was `ghc(i)`. No stack, cabal, HLS or `ghcup` binary |
| 2022-07-31 12:06:29 +0200 | <tomsmeding> | Is there a ~/.ghcup directory? |
| 2022-07-31 12:06:39 +0200 | <Jade30> | yes, there was even after the failed install |
| 2022-07-31 12:06:41 +0200 | <maerwald> | Jade30: source ~/.ghcup/env |
| 2022-07-31 12:06:42 +0200 | <tomsmeding> | If so, is there stuff in ~/.ghcup/bin |
| 2022-07-31 12:07:03 +0200 | <tomsmeding> | What maerwald says, or just put that bin directory in your path however you wish |
| 2022-07-31 12:07:50 +0200 | <Jade30> | oops, forgot to open a new terminal for the changes on path to take effect |
| 2022-07-31 12:07:59 +0200 | <tomsmeding> | Though I wonder how ghc got in your path |
| 2022-07-31 12:07:59 +0200 | <Jade30> | works now |
| 2022-07-31 12:08:11 +0200 | <tomsmeding> | Jade30: do you have the ghc package installed from the arch repos? |
| 2022-07-31 12:08:17 +0200 | <Jade30> | tomsmeding xmonad dependency |
| 2022-07-31 12:08:22 +0200 | <tomsmeding> | Ah rip |
| 2022-07-31 12:08:48 +0200 | <Jade30> | is that "bad"? |
| 2022-07-31 12:08:51 +0200 | <ggVGc> | tomsmeding: yeah, you couldn't use & for that, since you can't create a 2-ary function where you only use one argument using it. So, in that situation you'd just write it out as in haskell, just that you have fn and end instead of \... |
| 2022-07-31 12:08:53 +0200 | <tomsmeding> | The two installations _should_ not interfere as long as .ghcup/bin is before /usr/bin in your path |
| 2022-07-31 12:09:16 +0200 | <Jade30> | it is |
| 2022-07-31 12:09:27 +0200 | <tomsmeding> | Jade30: they should not interfere, but if your path is not as you expect it sometimes, then it might create confusing situations |
| 2022-07-31 12:09:43 +0200 | <Jade30> | ok I'll keep it in mind. |
| 2022-07-31 12:09:55 +0200 | <Jade30> | Now I can finally continue my bf interpreter on desktop |
| 2022-07-31 12:10:04 +0200 | <Jade30> | Coding on my phone for two weeks was a pain |
| 2022-07-31 12:10:15 +0200 | <tomsmeding> | Jade30: symptom: "there are files missing in package `...'" or something similar :) |
| 2022-07-31 12:10:15 +0200 | <Jade30> | haha |
| 2022-07-31 12:10:25 +0200 | <Jade30> | got it! |
| 2022-07-31 12:10:33 +0200 | <tomsmeding> | Jade30: what did you use for haskell on phone? |
| 2022-07-31 12:10:48 +0200 | <tomsmeding> | ggVGc: makes sense :) |
| 2022-07-31 12:10:51 +0200 | <Jade30> | Termux with a virtual arch installation that ran ghc as a native package |
| 2022-07-31 12:11:02 +0200 | <tomsmeding> | ggVGc: Not even necessarily a bad thing |
| 2022-07-31 12:11:03 +0200 | <Jade30> | it was barely working haha |
| 2022-07-31 12:11:10 +0200 | <tomsmeding> | Jade30: native termux now has a ghc package too! |
| 2022-07-31 12:11:16 +0200 | <tomsmeding> | Since a few months or so |
| 2022-07-31 12:11:17 +0200 | <Jade30> | oh, neat! |
| 2022-07-31 12:11:29 +0200 | <tomsmeding> | And cabal and friends |
| 2022-07-31 12:11:29 +0200 | <Jade30> | won't need it anymore thankfully |
| 2022-07-31 12:11:53 +0200 | <tomsmeding> | BF interpreter is top notch first project though :) |
| 2022-07-31 12:12:17 +0200 | <Jade30> | I'm basically done, I only need to parse the source into an AST |
| 2022-07-31 12:12:23 +0200 | <Jade30> | the evaluation thing is done |
| 2022-07-31 12:12:43 +0200 | <ggVGc> | after you write the BF interpreter you can drop all other languages and just use that |

| 2022-07-31 12:14:11 +0200 | <Jade30> | ggVGc hm? |
| 2022-07-31 12:14:18 +0200 | <ggVGc> | :) just joking |
| 2022-07-31 12:14:36 +0200 | <Jade30> | ok haha |
| 2022-07-31 12:14:37 +0200 | <ggVGc> | but, I think it'd be possible to implement a BF interpreter on the type-level in haskell |
| 2022-07-31 12:14:47 +0200 | <ggVGc> | e.g your BF proram would "run" at compile time |
| 2022-07-31 12:15:09 +0200 | <Jade30> | oh wow |
| 2022-07-31 12:15:15 +0200 | <Jade30> | that's interesting |
| 2022-07-31 12:15:32 +0200 | <ggVGc> | yes, but not necessarily good :) |
| 2022-07-31 12:15:32 +0200 | <Jade30> | that'd mean the compiler as a "language" is turing complete? |

| 2022-07-31 12:16:13 +0200 | <ggVGc> | but, you can have type-level functions and type-level data so... |
| 2022-07-31 12:17:03 +0200 | <tomsmeding> | Jade30: looking good! |
| 2022-07-31 12:17:10 +0200 | <Jade30> | ok now I wanna set up HLS for neovim |

| 2022-07-31 12:19:35 +0200 | <Jade30> | hm? |
| 2022-07-31 12:19:37 +0200 | <tomsmeding> | There is a crashing issue that was resolved recently |
| 2022-07-31 12:19:51 +0200 | <Jade30> | Oh I didn't boot my desktop for over 14 days |
| 2022-07-31 12:19:55 +0200 | <Jade30> | It was before that+ |
| 2022-07-31 12:20:02 +0200 | <tomsmeding> | Oh not _that_ recently :p |
| 2022-07-31 12:20:07 +0200 | <tomsmeding> | A month or two or so |
| 2022-07-31 12:21:05 +0200 | <naso> | anyone familiar with using Gen.discard or Gen.filter in hedgehog? i'm trying to get an element from a list that can possibly be empty, using https://paste.tomsmeding.com/Bd6DBwtd , but it is not working -- sometimes it has an error that the list is empty |
| 2022-07-31 12:21:28 +0200 | <ggVGc> | I often wonder why we need a different set of stuff for type-level calculations, if the type system is turing complete anyway. Why not just write normal haskell in special blocks, using types as the values? |
| 2022-07-31 12:21:54 +0200 | <naso> | (that's not the actual code, just trying to demonstrarte the issue) |
| 2022-07-31 12:22:01 +0200 | <tomsmeding> | naso: if null xs then Gen.discard else Gen.element f ? |
| 2022-07-31 12:22:38 +0200 | <tomsmeding> | ggVGc: Have you ever tried programming in Idris or Agda :p |
| 2022-07-31 12:22:58 +0200 | <ggVGc> | no, only looked at it a little bit a long time ago. But, is that the case there? |
| 2022-07-31 12:23:06 +0200 | <tomsmeding> | Haakell's type system is turing complete only accidentally due to a bunch of extensions, I believe |
| 2022-07-31 12:23:34 +0200 | <ggVGc> | I don't think we need to go as far as dependent types to do what I suggested |
| 2022-07-31 12:23:37 +0200 | <tomsmeding> | ggVGc: The point of a dependently typed language is that the language of types is the same as the language of values |
| 2022-07-31 12:23:43 +0200 | <Jade30> | Thanks for the suggestions! I actually told my friend about just that, rewriting the `>>` using do-notation :D |
| 2022-07-31 12:23:44 +0200 | <Jade30> | Is there any case where manual monad operations should *not* be replaced with `do`? |
| 2022-07-31 12:23:48 +0200 | <tomsmeding> | Hence you have types of types, types of types of types, etc |
| 2022-07-31 12:24:05 +0200 | <ggVGc> | tomsmeding: well, it's more than that though. It's that you can influence typing based on runtime values, right? Which is more powerful than what I am talkin about |
| 2022-07-31 12:24:19 +0200 | <tomsmeding> | Jade30: it's equivalent, so in principle no |
| 2022-07-31 12:24:26 +0200 | <tomsmeding> | Except for style, which is subjective |
| 2022-07-31 12:24:32 +0200 | <ggVGc> | I just mean that instead of "type family" we can have a special block of haskell and say "Foo :: TypeA -> TypeB" |
| 2022-07-31 12:24:54 +0200 | <tomsmeding> | ggVGc: Can you partially apply a type family in your system? |
| 2022-07-31 12:24:54 +0200 | <Jade30> | Yeah I was referring to style |
| 2022-07-31 12:25:10 +0200 | <naso> | tomsmeding: thanks, sorry my example was too simple and i'm not sure how to apply your suggestion. this is more like it https://paste.tomsmeding.com/92hW7UUa |
| 2022-07-31 12:25:13 +0200 | <tomsmeding> | Jade30: asking 5 haskell programmers about style will give 6 different answers |
| 2022-07-31 12:25:30 +0200 | <Jade30> | hahaha |
| 2022-07-31 12:25:30 +0200 | <ggVGc> | tomsmeding: no, not initially, since I don't think current Haskell supports that? :) |
| 2022-07-31 12:25:34 +0200 | <Jade30> | yeah I see |
| 2022-07-31 12:25:40 +0200 | <tomsmeding> | ggVGc: indeed :p |
| 2022-07-31 12:25:54 +0200 | <ggVGc> | I am talking about having exactly the features we have now, but with the same syntax, just in different blocks |
| 2022-07-31 12:26:03 +0200 | <ggVGc> | and in this special block, there can be restrictions |
| 2022-07-31 12:26:08 +0200 | <ggVGc> | like no partial application |
| 2022-07-31 12:26:18 +0200 | <ggVGc> | it would still be easier to use than the current combination of stuff |
| 2022-07-31 12:26:24 +0200 | <ggVGc> | I think... |

| 2022-07-31 12:31:03 +0200 | <Jade30> | Is there an easier way to do default/starting args than defining `f` as `f' default_arg` where `f'` takes all args? |

| 2022-07-31 12:32:04 +0200 | <tomsmeding> | Jade30: not really, though you can put the f' in a where block on f; this is a common pattern, where that f' is then typically called "go" |
| 2022-07-31 12:32:32 +0200 | <Jade30> | I see, thanks |
| 2022-07-31 12:33:59 +0200 | <Jade30> | ok, maybe I did something wrong; running `stack run` is downloading `GHC` again (?) |
| 2022-07-31 12:34:12 +0200 | <tomsmeding> | Jade30: stack manages its own ghcs |
| 2022-07-31 12:34:20 +0200 | <tomsmeding> | Use cabal if you want to use the ghcup-installed ghc |
| 2022-07-31 12:34:38 +0200 | <tomsmeding> | Or use stack and remove the ghcup-installed ghcs to save disk space :p |
| 2022-07-31 12:34:41 +0200 | <Jade30> | oh ok, this is fine I think |
| 2022-07-31 12:34:52 +0200 | <tomsmeding> | (or use system-ghc: true in stack.yaml, but please don't) |
| 2022-07-31 12:34:59 +0200 | <Jade30> | I have plenty of disk space, this shouldn't be too bad haha |
| 2022-07-31 12:35:05 +0200 | <Jade30> | Do you think Stack or Cabal is better? |

| 2022-07-31 12:35:53 +0200 | <tomsmeding> | These days it doesn't matter all that much, details are different but overall preference is subjective |
| 2022-07-31 12:35:58 +0200 | <Jade30> | haha, looks like a lot of things make everything go up in flames in haskell land |
| 2022-07-31 12:36:24 +0200 | <tomsmeding> | I personally prefer cabal, but feel free to use stack if you wish |
| 2022-07-31 12:36:39 +0200 | <tomsmeding> | Getting started easily trumps ideological perfection |
| 2022-07-31 12:37:00 +0200 | <ggVGc> | I use stack still, but cabal build times are faster... |
| 2022-07-31 12:37:13 +0200 | <ggVGc> | there are somethings with stack I don't know how to do with cabal |
| 2022-07-31 12:37:19 +0200 | <ggVGc> | like 'stack ghci' |

| 2022-07-31 12:37:49 +0200 | <Jade30> | Ok, all the advantages of neovim aside, this is too much of a pain rn, I'll just use `vscode(ium)` |
| 2022-07-31 12:37:54 +0200 | <ggVGc> | I had some issues with that in the past if I remember correctly... relating to it not loading all the modules I wanted or something |
| 2022-07-31 12:38:01 +0200 | <ggVGc> | might look into making the switch again sometimes |
| 2022-07-31 12:38:03 +0200 | <ggVGc> | sometime* |
| 2022-07-31 12:38:05 +0200 | <tomsmeding> | Ah |
| 2022-07-31 12:38:21 +0200 | <Jade30> | Unless theres something better than vsc? some plugin for a jetbrains ide/something similar? |
| 2022-07-31 12:38:39 +0200 | <Jade30> | I think theres an IntelliJ plugin but idk how good it is |
| 2022-07-31 12:38:42 +0200 | <tomsmeding> | Vscode is the best in integration with hls currently |
| 2022-07-31 12:38:46 +0200 | <Jade30> | ok cool |
| 2022-07-31 12:38:53 +0200 | <tomsmeding> | I have neovim working, but if you can stand vscode... :) |
| 2022-07-31 12:38:57 +0200 | <ggVGc> | vim+coc+haskell-language-server works quite well for me |
| 2022-07-31 12:39:00 +0200 | <tomsmeding> | Probably easier |
| 2022-07-31 12:39:16 +0200 | <Jade30> | I'm rather new to vim so I need to get used to a lot of stuff |

| 2022-07-31 14:43:53 +0200 | <ggVGc> | tomsmeding: the usecase is basically this: data Thing = Thing {inputs :: [(String, Range)]} |
| 2022-07-31 14:44:30 +0200 | <ggVGc> | and the ranges are for checking of something can be connected to a certain input |
| 2022-07-31 14:45:37 +0200 | <tomsmeding> | ggVGc: is your problem that the various Range objects need to have different type tags? |
| 2022-07-31 14:46:26 +0200 | <ggVGc> | yeah, so I need to rethink how to model this I guess. Basically "input1" could have Positive range, and "input2" could have a Nullable (Range Int Int) |
| 2022-07-31 14:46:48 +0200 | <tomsmeding> | Right, then you can't model this in the type system |

| 2022-07-31 14:47:34 +0200 | <tomsmeding> | Well, what you could do is move Ty to the value level, but then make Ty a gadt so that pattern matching on a Ty can reconstruct the type-level info |

| 2022-07-31 15:49:10 +0200 | <ggVGc> | hah... |
| 2022-07-31 15:49:31 +0200 | <tomsmeding> | Standard rules are quite conservative, and sufficient to guarantee convergence, if I remember correctly |
| 2022-07-31 15:49:49 +0200 | <tomsmeding> | But there are plenty of convergent things that aren't covered by those rules |
| 2022-07-31 15:50:07 +0200 | <tomsmeding> | Where with "convergent" I mean "doesn't loop indefinitely" |
| 2022-07-31 15:50:43 +0200 | <tomsmeding> | UndecidableInstances doesn't break semantics, it just allows inference to not terminate, possibly |
| 2022-07-31 15:50:56 +0200 | <tomsmeding> | If inference terminates, the result is still correct |
| 2022-07-31 15:51:01 +0200 | <tomsmeding> | So it's quite safe |
| 2022-07-31 15:53:11 +0200 | <merijn> | ggVGc: UndecidableInstances (despite the same) is safe in the sense that "code that finishes compiling will be correct" |
| 2022-07-31 15:53:17 +0200 | <merijn> | s/same/name |
| 2022-07-31 15:53:32 +0200 | <merijn> | (correct in a typing sense, not necessarily behaviour :p) |
| 2022-07-31 15:55:54 +0200 | <ggVGc> | ah, cool. Have to admit I never really fully understood the caveats of it |
| 2022-07-31 15:56:33 +0200 | <merijn> | ggVGc: By default GHC is very conservative in type level functions and typeclass tomfoolery, meaning it only allows things that provably always terminate |
| 2022-07-31 15:57:31 +0200 | <merijn> | ggVGc: UndecidableInstances allows things for which it is undecidable if they (the typeclass tomfoolery) terminates. So, hypothetically, you can end up with code which does not terminate and compilation never finishes |
| 2022-07-31 15:57:48 +0200 | <merijn> | (in practice, GHC has a maximum number of evaluation steps before it gives up and says "no") |

| 2022-07-31 16:35:04 +0200 | <onosendi> | Thank you. I feel like this Tutorial skipped over a bunch of stuff, heh. |
| 2022-07-31 16:35:37 +0200 | <geekosaur> | in general you create values the same way you declare them |
| 2022-07-31 16:35:57 +0200 | califax | (~califax@user/califx) |
| 2022-07-31 16:36:41 +0200 | <geekosaur> | so if you have `data Person = Person {name :: String, age :: Int}` then a value of type Person is `person {name = "Fred", age = 50}` |
| 2022-07-31 16:37:33 +0200 | <geekosaur> | and similarly for yesterday when you had `calc` and needed a value to go with it, and had it declared as `Add Int Int | Sub Int Int` |

| 2022-07-31 16:38:03 +0200 | <geekosaur> | but for that one you needed parentheses because `Add` and `Sub` can be used directly as values with function types |

| 2022-07-31 16:49:10 +0200 | <geekosaur> | especially when learning, it may be better to name the term and type level ones differently to help keep them separate |

| 2022-07-31 16:50:32 +0200 | <onosendi> | So that's not considered recursive datatypes? A few videos before there was an example `data PeaNum = Succ PeaNum | Zero`, which was recursive? |
| 2022-07-31 16:51:00 +0200 | <geekosaur> | that one is recursive because `Succ PraNum` refers to the type, not a value |

| 2022-07-31 17:56:18 +0200 | <[itchyjunk]> | i'll make a note to try it with span after this |
| 2022-07-31 17:56:26 +0200 | <monochrom> | But mine is not an alternative. |

| 2022-07-31 17:57:15 +0200 | <monochrom> | You wanna access the first word of f xs? Well first you have to address what happens if there is no first word. |
| 2022-07-31 17:57:32 +0200 | <monochrom> | Then the logical conclusion is you need pattern matching. |

| 2022-07-31 18:48:11 +0200 | <[exa]> | unfortunately PHP is a feature of wordpress |
| 2022-07-31 18:48:33 +0200 | <[itchyjunk]> | the guard is breaking my function h i think |

| 2022-07-31 18:48:38 +0200 | <Inst> | from what I've heard, apparently Warp/WAI is substantially faster than the PHP equivalent |
| 2022-07-31 18:48:46 +0200 | <[itchyjunk]> | when i try just span on my ghci, it seems to somewhat work |

| 2022-07-31 21:27:25 +0200 | <darkling> | Depends on whether you're Dutch or not. |
| 2022-07-31 21:27:26 +0200 | <dolio> | The argument above kind of applies to anything. |
| 2022-07-31 21:27:50 +0200 | <dolio> | Prolog is declarative, but if you want to write good programs, you need to care about its operational semantics. |
| 2022-07-31 21:28:06 +0200 | <c_wraith> | I was just thinking this morning - one of my favorite comedy groups had a former member who was like 6'9", but nobody realized it because everyone else in the group was also really tall, so he just looked a little tall relatively. |

| 2022-07-31 21:29:55 +0200 | <c_wraith> | conclusion: you will always eventually care about performance, at which point operational concerns start showing up where you care about the "how" as much as the "what" |

| 2022-07-31 21:30:24 +0200 | <dolio> | Yeah, I'm not sure we're anywhere close to "declarative" programming if that's the criteria. |
| 2022-07-31 21:31:33 +0200 | <dolio> | You need something like the Conor McBride dream, where you just write the types, and the computer is good enough to figure out a good program. |
| 2022-07-31 21:32:24 +0200 | <EvanR> | there's this niche area of programming where you write in dynamic webdev languages with terrible performance, with no possibility of making it perform better, and it somehow works xD |
| 2022-07-31 21:32:59 +0200 | <dolio> | Eventually you have to care even with those. |
| 2022-07-31 21:33:04 +0200 | <EvanR> | if they were simply declarative instead of imperative it would seem to defy this logic that you eventually need operational semantics |
| 2022-07-31 21:33:42 +0200 | <monochrom> | My dream exceeds that. In my dream, the type also includes time bounds. |

| 2022-07-31 21:45:38 +0200 | <hololeap> | using parsec, when you run a parser inside a parser e.g. you parse some string fragment and want to run another parser on it, is there a way to throw any resulting ParseError inside the larger parser? |

| 2022-07-31 21:47:20 +0200 | <hololeap> | it really boils down to: ? :: ParseError -> ParsecT s u m a |
| 2022-07-31 21:47:41 +0200 | <monochrom> | ParsecT is an instance of MonadError, so I guess throwError |

| 2022-07-31 22:28:38 +0200 | <Lycurgus> | hledger c. '2014/5 |
| 2022-07-31 22:29:07 +0200 | <Lycurgus> | and the cli ledger ecosys generally of that time |
| 2022-07-31 22:29:43 +0200 | <sm> | whew, 8 years.. summarising that is a bit of work |
| 2022-07-31 22:29:59 +0200 | <Lycurgus> | alpine looks like bad news |
| 2022-07-31 22:30:10 +0200 | <sm> | its like Ledger implemented in more depth, more robustly, with better UX |
| 2022-07-31 22:30:31 +0200 | <Lycurgus> | well i was running hledger-web at one point |
| 2022-07-31 22:30:45 +0200 | <Lycurgus> | it used to be a pain to build |
| 2022-07-31 22:30:55 +0200 | <Lycurgus> | well not a pain but not a snap either |
| 2022-07-31 22:31:05 +0200 | <sm> | building should be routine on non-exotic platforms |
| 2022-07-31 22:31:16 +0200 | <sm> | and there are more binaries these days |
| 2022-07-31 22:31:43 +0200 | <Lycurgus> | yesod based iirc |
| 2022-07-31 22:32:05 +0200 | <Lycurgus> | (the web part) |
| 2022-07-31 22:32:24 +0200 | <Lycurgus> | maybe misremember and it was just wai |
| 2022-07-31 22:32:27 +0200 | <sm> | back then building yesod was a bit scary probably, not today |

| 2022-07-31 22:33:46 +0200 | <Lycurgus> | anyway that's my guess base OS elements not playing nice with your build/ci intentions |
| 2022-07-31 22:34:40 +0200 | <sm> | thanks.. that doesn't narrow it down too much. It was building fine before of course |
| 2022-07-31 22:35:03 +0200 | <sm> | guess I'll try an older ghc |

| 2022-07-31 22:36:07 +0200 | <sm> | and indeed I don't know why it needs to be alpine, I could try changing that |
| 2022-07-31 22:37:05 +0200 | <monochrom> | If you didn't choose alpine but something/someone did, it's probably because alpine is reputed to be a very minimal and friendly-to-static-linking linux. |
| 2022-07-31 22:41:34 +0200 | <sm> | yes that sounds right monochrom |
| 2022-07-31 22:42:08 +0200 | <sm> | looking more carefully, it mostly does fail in the same place, Hledger.Cli.DocFiles, or another package, both of which probably involve TH/QQ. That could be a clue |
| 2022-07-31 22:42:30 +0200 | <sm> | more troubleshooting next time |
