| 2024-11-08 13:52:04 +0100 | <yin> | philosophically, are records just a data structure that we give the compiler permission to optimize however it sees fit or is there something more to it? |
| 2024-11-08 13:52:24 +0100 | <kqr> | Text.Printf does not come with an instance for Text. When I poke around I see some suggestions to use Data.Text.Format instead. Is this actually preferred? I find very little comparison online. The use case is not large templating but creating a Show instance for a custom numeric type – so I'm hesitant to reach for something that's not in base. |
| 2024-11-08 13:53:22 +0100 | <Rembane> | yin: IIRC it's syntactic sugar for not having to write out all the access functions and save functions for a datatype. |

| 2024-11-08 13:57:45 +0100 | <Rembane> | yin: As product types plus some functions. Like the `data` types with many arguments without the record stuff. |
| 2024-11-08 13:57:57 +0100 | <Leary> | yin: It's a matter of interface, not representation. With regular product types, you only have positional notation for manipulating contained values. Records just let you specify them with names instead. |

| 2024-11-08 17:55:18 +0100 | <geekosaur> | yin, I think optics or not is more of a stylistic choice. and Haskell is not Python with its "there is only One True Way" mentality |

| 2024-11-08 18:04:28 +0100 | <tomsmeding> | magic_rb: your parser is going to see the '(' which makes the first alternative of parseOp happy, so you recurse into parseOp |

| 2024-11-08 18:07:22 +0100 | <tomsmeding> | parseOpOr starts by parsing parseOp, so if the between, parseOpEqual, parseOpNot and parseOpIn parsers fail, then you're going to loop parseOp -> parseOpOr -> parseOp -> parseOpOr -> ... |
| 2024-11-08 18:07:36 +0100 | <tomsmeding> | this is called "left recursion" in a grammar |
| 2024-11-08 18:08:44 +0100 | <tomsmeding> | magic_rb: this doesn't use a parser library, it does things manually, but it's a nice intro into multiple precedence levels (* goes before +, etc.) and how to handle them in a parser |
| 2024-11-08 18:09:10 +0100 | <EvanR> | since parens are required you don't have to know anything about precedence but you do need to avoid left recursion |
| 2024-11-08 18:09:39 +0100 | <tomsmeding> | that hfm article cheats out by parsing all operators as right-associative (i.e. `a + b + c` means `a + (b + c)`, not `(a + b) + c`), which avoids the left-recursion problem |

| 2024-11-08 18:11:14 +0100 | <haskellbridge> | <magic_rb> ok ill read that thing over the weekend and come back to my thing after it... i did not anticipate parsing being so difficult |
| 2024-11-08 18:11:58 +0100 | <EvanR> | i.e. (a == tags) || (c -> tags) || (e -> tags) can get away with not associating or precedencing |
| 2024-11-08 18:12:29 +0100 | <mauke> | left recursion is basically just a function unconditionally calling itself |
| 2024-11-08 18:12:37 +0100 | <mauke> | which obviously cannot terminate |
| 2024-11-08 18:12:39 +0100 | <EvanR> | and these operators except for == seem to make no sense when chained xD |
| 2024-11-08 18:12:45 +0100 | <EvanR> | er except for || |

| 2024-11-08 18:14:17 +0100 | <EvanR> | magic_rb, your language seems pretty straightforward, it's probably just a small bug somewhere |
| 2024-11-08 18:14:30 +0100 | <tomsmeding> | I think there are two bugs: missing 'try', and left recursion |
| 2024-11-08 18:14:50 +0100 | <haskellbridge> | <magic_rb> i have try |
| 2024-11-08 18:15:16 +0100 | <tomsmeding> | magic_rb: your parser for `||` wants an op on both sides |
| 2024-11-08 18:15:17 +0100 | <haskellbridge> | <magic_rb> https://paste.tomsmeding.com/hq0SOVbH |
| 2024-11-08 18:15:20 +0100 | <tomsmeding> | that isn't going to work |
| 2024-11-08 18:15:42 +0100 | <tomsmeding> | because you're already parsing an op, and when you're at the beginning of parseOpOr you don't know yet if there will be a `||` coming |
| 2024-11-08 18:15:42 +0100 | <EvanR> | something like, term = try p1 <|> try p2 <|> try p3 <|> try p4, if any of those might test more than 1 character before failing |
| 2024-11-08 18:16:21 +0100 | <haskellbridge> | <magic_rb> tomsmeding: ok so what do i do to make it work :) |
| 2024-11-08 18:16:31 +0100 | <tomsmeding> | magic_rb: I think the 'try' around the between parser is technically unnecessary because megaparsec does backtrack if the very first primitive parser in a branch fails, and `symbol` does only one primitive thing |

| 2024-11-08 18:18:05 +0100 | <mauke> | wasn't there a precedence parser generator somewhere? |
| 2024-11-08 18:18:05 +0100 | <haskellbridge> | <magic_rb> ah so split "parseOp" into multiple levels |
| 2024-11-08 18:18:35 +0100 | <tomsmeding> | e.g. in arithmetic, make parsePlusMinus, parseTimesDivide, parseAtom; parsePlusMinus first calls parseTimesDivide to get the a non-`+-` thing, then it tries + or - |
| 2024-11-08 18:18:36 +0100 | <EvanR> | are we just ignoring the information that there will only ever be (a op b), two things parenthesized |
| 2024-11-08 18:18:44 +0100 | <tomsmeding> | EvanR: that's irrelevant |

| 2024-11-08 18:18:53 +0100 | <EvanR> | sure it will still work but be unnecessary |
| 2024-11-08 18:19:16 +0100 | <tomsmeding> | if you want every single binary op to be parenthesised, you're just saying "I have two precedence levels: operators and parentheses" |
| 2024-11-08 18:19:20 +0100 | <EvanR> | by seeing if the first character is ( or " you know what to do |
| 2024-11-08 18:19:22 +0100 | <tomsmeding> | you still need to put parentheses in a separate thing |
| 2024-11-08 18:19:41 +0100 | <tomsmeding> | because otherwise what is the parser going to do if it sees "a && b || c" |
| 2024-11-08 18:19:45 +0100 | <EvanR> | recurse or begin a binary term |
| 2024-11-08 18:19:48 +0100 | <tomsmeding> | sure, it's invalid, but currently it'll loop |
| 2024-11-08 18:20:07 +0100 | <EvanR> | got it, ignoring the information about there only ever being (a op b) |
| 2024-11-08 18:20:10 +0100 | <tomsmeding> | the very easiest version is to require _every_ binary operation to be wrapped in parentheses |
| 2024-11-08 18:20:17 +0100 | <tomsmeding> | including the top level |
| 2024-11-08 18:20:17 +0100 | <EvanR> | that's what I said |
| 2024-11-08 18:20:22 +0100 | <EvanR> | no |
| 2024-11-08 18:20:23 +0100 | <tomsmeding> | but then you still have two functions! |
| 2024-11-08 18:20:37 +0100 | <tomsmeding> | parseParenthesised, which calls out to parseOp which does the <|> chain |
| 2024-11-08 18:20:43 +0100 | <tomsmeding> | which calls parseParenthesised again |
| 2024-11-08 18:21:00 +0100 | <EvanR> | as long as you don't have an infinite series of ((((((... that's fine |
| 2024-11-08 18:21:08 +0100 | <tomsmeding> | if you then want parentheses at the top level to be optional, you can start with parseParenthesised <|> parseOp at the top level |

| 2024-11-08 18:21:16 +0100 | <tomsmeding> | EvanR: how would the parser look then :p |
| 2024-11-08 18:21:38 +0100 | <EvanR> | I think they just need try around several choices in the <|> chain |
| 2024-11-08 18:21:48 +0100 | <tomsmeding> | EvanR: they already have that, now there's left recursion |
| 2024-11-08 18:21:53 +0100 | <tomsmeding> | in || and in && |
| 2024-11-08 18:21:53 +0100 | <haskellbridge> | <magic_rb> ^ |
| 2024-11-08 18:22:17 +0100 | <EvanR> | not in the version I'm seeing |
| 2024-11-08 18:22:23 +0100 | <tomsmeding> | they posted a new paste |
| 2024-11-08 18:22:26 +0100 | <tomsmeding> | https://paste.tomsmeding.com/hq0SOVbH |
| 2024-11-08 18:22:44 +0100 | <EvanR> | that's not doing direct left recursion it tests for ( first |
| 2024-11-08 18:22:58 +0100 | <EvanR> | it can fail before recursing |
| 2024-11-08 18:23:04 +0100 | <mauke> | that's only half the code |
| 2024-11-08 18:23:14 +0100 | <mauke> | I suspect mutual recursion |
| 2024-11-08 18:23:15 +0100 | <tomsmeding> | okay so for `a || b`, the first character is not ( |
| 2024-11-08 18:23:29 +0100 | <haskellbridge> | <magic_rb> https://paste.tomsmeding.com/wsx4oGSc so now have that, how exactly does that get me anywhere |
| 2024-11-08 18:23:29 +0100 | <tomsmeding> | so then it enters, at some point, parseOpOr, because the previous ones fail |
| 2024-11-08 18:23:35 +0100 | <tomsmeding> | then it recurses to parseOp immediately |
| 2024-11-08 18:23:37 +0100 | <tomsmeding> | this is left recursion |
| 2024-11-08 18:24:01 +0100 | <EvanR> | the structure is a bit weird, this is supposedly "parse operator expression, parseOp" but it's try to parse a "primary" (parenthesized expression) |
| 2024-11-08 18:24:08 +0100 | <tomsmeding> | magic_rb: what is the top level? |
| 2024-11-08 18:24:10 +0100 | <EvanR> | which is something else |
| 2024-11-08 18:24:23 +0100 | <haskellbridge> | <magic_rb> tomsmeding: i dont have that yet, not sure what is it supposed to be |
| 2024-11-08 18:24:38 +0100 | <mauke> | https://markkarpov.com/tutorial/megaparsec.html#parsing-expressions |
| 2024-11-08 18:24:47 +0100 | <mauke> | has anyone mentioned this yet? |
| 2024-11-08 18:25:05 +0100 | <tomsmeding> | that's cheating, that uses buildExpressionParser :p |
| 2024-11-08 18:25:26 +0100 | <tomsmeding> | uh, makeExprParser (it's called buildExpressionParser in parsec) |
| 2024-11-08 18:25:29 +0100 | <EvanR> | sorry, I brought that up first but, but since it's just (a op b), it's overkill |
| 2024-11-08 18:25:48 +0100 | <EvanR> | but I see that might be wrong because you can do term || term || term || term |
| 2024-11-08 18:25:54 +0100 | <mauke> | works, though |
| 2024-11-08 18:26:02 +0100 | <haskellbridge> | <magic_rb> (and i think id like to know how to do it myself, because im completely lost right now) |

| 2024-11-08 18:26:54 +0100 | <tomsmeding> | magic_rb: is it `==` and `->` are at the same level, they go before `&&`, and `&&` goes before `||`? |
| 2024-11-08 18:26:59 +0100 | <EvanR> | the classic way is to divide the term language into primary expression and operator expression, and (...) is a primary not an operator |
| 2024-11-08 18:27:50 +0100 | <EvanR> | so those two kinds of expression correspond with 2 parsers |
| 2024-11-08 18:27:53 +0100 | <haskellbridge> | <magic_rb> tomsmeding: uh, ive no clue, ive confused myself beyond reason. Ill pick this up later, i gotta run anyway |
| 2024-11-08 18:28:14 +0100 | <haskellbridge> | <magic_rb> thanks everyone for trying to help me :) |
| 2024-11-08 18:28:30 +0100 | <EvanR> | I confused myself by try to dumb down the language xD |
| 2024-11-08 18:28:43 +0100 | <EvanR> | without chaining different operators |
| 2024-11-08 18:28:48 +0100 | <haskellbridge> | <sm> hello, I am once again urging you to insert dbg or at least trace calls in every parse step so you can see operationally what is happening, it’s very difficult to mentally debug parser combinators |
| 2024-11-08 18:28:56 +0100 | <haskellbridge> | <sm> :) |
| 2024-11-08 18:29:15 +0100 | <haskellbridge> | <magic_rb> will do, after i figure out how to actually use that :) and read it :) |
| 2024-11-08 18:29:37 +0100 | <haskellbridge> | <sm> 👍 |
| 2024-11-08 18:29:49 +0100 | <haskellbridge> | <magic_rb> tom asked me what bound tighter and my brains response was "uh, && before || yes" |
| 2024-11-08 18:30:05 +0100 | <haskellbridge> | <magic_rb> i think im done for now 😂, thanks again |
| 2024-11-08 18:30:08 +0100 | <mauke> | the traditional way to do rec-descent infix expressions is to have a hierarchy of expression parsers. like expr3 = do { expr2; op "+"; expr3 }; expr2 = do { expr1; op "*"; expr 2 }; expr1 = do { expr0; op "**"; expr1 } expr0 = between "(" ")" expr3 <|> term |
| 2024-11-08 18:30:37 +0100 | <haskellbridge> | <magic_rb> wouldnt that mean you cant have "(4 + 3) + 2"? |
| 2024-11-08 18:30:53 +0100 | <haskellbridge> | <sm> You are worthy opponent, parser combinators, but they shall return ✊ |
| 2024-11-08 18:31:07 +0100 | <mauke> | no, that would work fine |
| 2024-11-08 18:31:27 +0100 | <mauke> | we start in expr3 (the top level) |
| 2024-11-08 18:32:26 +0100 | <mauke> | then we immediately climb down the hierarchy to expr0, which consumes the leading "(" |
| 2024-11-08 18:33:11 +0100 | <mauke> | then we try expr3 again. (current call stack: expr3 -> expr2 -> expr1 -> expr0 -> between -> expr3) |
| 2024-11-08 18:33:53 +0100 | <mauke> | the inner instance of expr3 climbs down the hierarchy again, but this time there is no "(" to be consumed, so expr0 tries term |
| 2024-11-08 18:34:00 +0100 | <mauke> | which presumably successfully consumes 4 |
| 2024-11-08 18:34:01 +0100 | <EvanR> | so basically, try "(" term ")" last |
| 2024-11-08 18:34:42 +0100 | <mauke> | then we return all the way back up the hierarchy, trying all operators in turn (and failing), until we arrive at expr3 again and op "+" succeeds |
| 2024-11-08 18:35:20 +0100 | <mauke> | then expr3 calls itself (because for simplicity, all of my operators are right associative) |

| 2024-11-08 18:39:52 +0100 | <mauke> | so when 'between' consumes ")", we return back up the expr hierarchy and try all the possible operators on the way up |

| 2024-11-08 19:51:35 +0100 | <famubu> | is a functor. That means it's like a function whose 'argument' is a category, right? And `η` is a natural transformation, not a category. |
| 2024-11-08 19:51:49 +0100 | <famubu> | * `T` is a functor. |
| 2024-11-08 19:51:56 +0100 | <famubu> | I am not that familiar with category theory. |
| 2024-11-08 19:56:51 +0100 | <tomsmeding> | famubu: a functor from C to C' consists of a mapping from Ob C to Ob C' and a mapping from the arrows in C to the arrows in C' |

| 2024-11-08 19:57:56 +0100 | <tomsmeding> | if you have a natural transformation between two functors T1 and T2, and a functor T, then you can build a natural transformation from T . T1 to T . T2 |
| 2024-11-08 19:58:10 +0100 | <tomsmeding> | they denote that by applying T to the natural transformation |
| 2024-11-08 19:58:37 +0100 | <tomsmeding> | see e.g. the third commutative diagram: you have mu_X on the bottom arrow, and T(mu_X) on the top arrow |
| 2024-11-08 19:58:51 +0100 | <tomsmeding> | the difference is that the source and target of T(mu_X) have an additional T() around them |

| 2024-11-08 20:07:43 +0100 | <kqr> | Hm. I'm looking at doing some validation in an Attoparsec parser and I want to fail the parse if the validation fails – ideally with a value of some custom error type. I feel like I have done this before but I cannot for the life of me figure out how I did it now. |
| 2024-11-08 20:11:15 +0100 | <kaol> | ExceptT is one option. |
| 2024-11-08 20:11:41 +0100 | <kqr> | Hm. I'd hoped I could hook into the parser monad itself, but maybe it doesn't support failure in the way I think of it? |
| 2024-11-08 20:11:50 +0100 | <tomsmeding> | it has `fail` if you're okay with strings |
| 2024-11-08 20:12:57 +0100 | <tomsmeding> | and the type that `fail` uses in the parser monad looks pretty monomorphically String |
| 2024-11-08 20:13:19 +0100 | <geekosaur> | afaik `fail` itself requires it? |
| 2024-11-08 20:13:43 +0100 | <tomsmeding> | "requires"? |
| 2024-11-08 20:13:57 +0100 | <geekosaur> | https://downloads.haskell.org/ghc/latest/docs/libraries/base-4.20.0.0-1f57/Control-Monad-Fail.html… |
| 2024-11-08 20:14:09 +0100 | <geekosaur> | `fail :: String -> m a` |
| 2024-11-08 20:14:16 +0100 | <tomsmeding> | sure, but the Parser monad doesn't support anything more general than String |
| 2024-11-08 20:14:17 +0100 | <kaol> | Are you sure you didn't do it with megaparsec the last time? It has more knobs including type variable for the error type. |
| 2024-11-08 20:14:19 +0100 | <tomsmeding> | is what I meant |
