[00:34] *** Guest4 joined [00:47] The documentation for 'reduce' seems to imply it will simply return the sole item of a list when given a list of length 1, but I always seem to get a "too few positionals passed" error when I try. It seems to work with some built-ins, like &infix:<+>, but not with anything else I try. Is the documentation wrong? [01:24] <[Coke]> can you give an example that fails? [01:24] <[Coke]> m: say reduce &infix:<->, (1,); [01:24] rakudo-moar f25d6a249: OUTPUT: «1␤» [01:25] <[Coke]> if your sub only takes 2 args, it can't take just 1, so this will fail: [01:25] <[Coke]> m: sub j($a, $b) { $a * $b }; say reduce &j, (1,); [01:25] rakudo-moar f25d6a249: OUTPUT: «Too few positionals passed; expected 2 arguments but got 1␤ in sub j at line 1␤ in block at line 1␤␤» [01:26] <[Coke]> m: sub j($a, $b=1) { $a * $b }; say reduce &j, (1,); [01:26] rakudo-moar f25d6a249: OUTPUT: «1␤» [01:26] <[Coke]> but since the second arg has a default there, that will work. [01:26] <[Coke]> Guest4: hope that helps. [01:31] Perhaps I am reading too much into the documentation. I was hoping I could avoid a bunch of length checks in my code and reduce would do it for me. [01:32] <[Coke]> are you trying to reduce with a builtin or your own 2-arg sub? [01:34] My own. Not dissimilar to your second example. [01:35] <[Coke]> ok. the core ones do this not by having a single sub doing 1 and 2 arg versions, but with a multi sub. [01:36] <[Coke]> e.g. there is a multi sub infix:<+>($x) { $x.Numeric } [01:36] <[Coke]> That's probably the easiest way to do it. Can you point me at the doc URL you were reading? I can add a note to that effect. [01:37] https://docs.raku.org/routine/reduce [01:45] It never occurred to me to try a mutli sub. Thanks for the help. [01:49] <[Coke]> I think the text there is incorrect, actually, it says: [01:49] <[Coke]> If list contains just a single element, the operator is applied to that single element if possible; if not, it returns the element itself. [01:50] <[Coke]> I'll rework that sentence to mention the multi (and double check the reduce implemenation that this isn't an error) [01:51] <[Coke]> Guest4: https://github.com/Raku/doc/issues/4816 [02:01] *** hulk joined [02:02] *** kylese left [02:15] *** hulk left [02:15] *** kylese joined [02:28] *** guifa_ left [02:29] *** guifa joined [02:33] *** rmv left [02:51] *** Guest4 left [03:03] *** leppard left [03:46] *** rmv joined [03:51] *** rmv left [04:39] *** hurufu joined [06:19] *** vrurg joined [06:22] *** vrurg_ left [06:33] *** rmv joined [06:38] *** rmv left [07:32] *** guifa left [07:32] *** guifa_ joined [07:39] *** leppard joined [08:34] *** tonyo left [08:35] *** rmv joined [08:36] *** tonyo joined [08:39] *** rmv left [08:49] *** tonyo left [08:53] *** tonyo joined [09:01] *** tonyo left [09:03] *** tonyo joined [09:16] *** tonyo left [09:28] *** tonyo joined [09:33] *** tonyo left [09:34] *** tonyo joined [09:46] I say docs about sleep and one thing is peculiar to me - there exists Duration (that sleep accepts) but Duration can't be initialized with minutes, hours etc. [09:51] *** tonyo left [09:51] it can be done easily so maybe it could be accepted form of .new [09:52] m: sub duration { my $n = DateTime.new(0); $n.later(|%_) - $n.$_ }; say duration(:2days); say duration :3hours; [09:52] rakudo-moar f25d6a249: OUTPUT: «172800␤10800␤» [09:57] *** tonyo joined [09:59] interesting idea [10:00] I guess it makes sense up to :weeks [10:04] *** oodani left [10:05] Duration having units overall makes sense, just maybe not when combined with sleep [10:05] *** oodani joined [10:06] m: sleep Duration.new(1); say now - INIT now [10:06] rakudo-moar f25d6a249: OUTPUT: «1.001584075␤» [10:06] think it works fine? [10:07] yeah, sleep accepts the duration [10:08] duration gets converted into numeric probably [10:10] either way, C# has similar class (it uses ticks internally) and it accepts `(d?, h,m,s)` as .new (and has ToString for that): https://github.com/microsoft/referencesource/blob/main/mscorlib/system/timespan.cs [10:10] actually, Duration nowadays store nanoseconds [10:10] *stores [10:14] *** tonyo left [10:16] tick in TimeSpan context is 100ns I think, so storing ns is more precise [10:16] + can use nanosleep directly [10:22] *** tonyo joined [10:23] *** rmv joined [10:24] *** rmv left [10:24] *** rmv joined [10:25] Hi everyone, trying to upload my first zef package.
