| 2025-01-08 01:38:10 +0100 | <orangeFlu> | You are basically making a chain of monads, piping the result from one to the other. if any of those Maybe's is Nothing, the whole thing is Nothing. It's just how this monad works |
| 2025-01-08 01:41:13 +0100 | <ncf> | if you think of Maybe as an exception/failure monad, then your program is do fail; pure ... |
| 2025-01-08 01:41:23 +0100 | <ncf> | this fails instead of returning anything, as in every language |
| 2025-01-08 01:41:48 +0100 | <ncf> | in other words >> discards values, not effects |
| 2025-01-08 01:42:45 +0100 | <orangeFlu> | If you know >>=, then >> is like it except it discards the result of the computation, like ncf said, it doesn't 'bind' it to anything |

| 2025-01-08 02:35:00 +0100 | <sim590> | I'm presently looking at how to make Haskell bindings for a C++ library. I'm reading https://wiki.haskell.org/Cxx_foreign_function_interface and I see that there are many approaches. From the history of the page, fficxx seems to have been brought up most recently. It doesn't mean it's best. I'm looking for an opinion as to what to look at first. |

| 2025-01-08 05:50:43 +0100 | <c_wraith> | the issue is that m [a] is a *single* action that produces an entire list. |
| 2025-01-08 05:51:00 +0100 | <c_wraith> | LogicT really wants to break that apart |
| 2025-01-08 05:52:22 +0100 | <hololeap> | c_wraith: I have some old code that uses ListT, and I'm trying to replace it so that it builds on newer base (since they removed ListT) |

| 2025-01-08 05:52:42 +0100 | <c_wraith> | you really should be using conduit or something for that |

| 2025-01-08 05:53:17 +0100 | <hololeap> | I felt like conduit would be overkill |

| 2025-01-08 06:00:35 +0100 | <c_wraith> | that's kind of the whole point of it. |

| 2025-01-08 06:36:40 +0100 | <monochrom> | Belated: Nothing >> pure foo = Nothing is pretty much forced by the monad laws. Several laws are involved, but the most damning one is k >>= pure = k, now let k be Nothing. |
| 2025-01-08 06:37:49 +0100 | <monochrom> | But if you prefer pragmatics to theory, every exception system, in every language, says that { throw Exception; return (div 5 2); } is going to throw that exception rather than return normally. |
| 2025-01-08 06:39:34 +0100 | <monochrom> | If you want Nothing ??? pure foo = pure foo, consider using <|> instead: Nothing <|> pure foo. In other words, you are looking for { throw Exception; } catch Exception { return foo; } |

| 2025-01-08 09:10:10 +0100 | <alist> | is this the right channel? haskell-in-depth seems to have very few people comparatively |
| 2025-01-08 09:11:01 +0100 | weary-traveler | (~user@user/user363627) (Quit: Konversation terminated!) |
| 2025-01-08 09:11:29 +0100 | <mauke> | potentially yes, but personally I'm not familiar with the paper (beyond the title) |
| 2025-01-08 09:12:15 +0100 | <alist> | ok, to be fair its a pretty specific question so no worries if you cant help |
| 2025-01-08 09:13:50 +0100 | <alist> | basically, on the top of page 6 the author expands the forall quantifier for relations by specializing the fold function for the types A and B. |
| 2025-01-08 09:14:55 +0100 | <alist> | but the definition of fold in that example is defined as (a->b->b)->a etc., where a, b are functions from A->A', B->B' |
| 2025-01-08 09:16:41 +0100 | <alist> | the previous page defines forall expansion and i think accordingly fold should be specialized to a, b (lowercase) in this instance my question |
| 2025-01-08 09:17:09 +0100 | <alist> | *my question is what am i missing, or did the author make a mistake |
