liAealneDx TimToady: I type them directly 00:08
but your point is that we should only add unicode versions if they're mangled by software? 00:09
SmokeMachine every time I try to make the doc, it stops on processed "./doc/Type/X/IO/Dir.pod6 (cached)" on my mac... I tried that on docker, and its passing... 00:11
liAealneDx if texas ops are mangled*
TimToady my point is that all the other things we've added have additional rationale besides "it'd be cool", but ⁇‼ is not math, it's not autocorrection, it's not helping disambiguate different kinds of angles, so what is it doing for us? 00:14
TimToady doesn't even know whyt Unicode has ⁇ and ‼... 00:16
liAealneDx just like it has …
TimToady that is much more heavily used in normal text 00:17
and has the autocorrection argument
BenGoldberg What category of operator is the ternary ??!!, anyway? I don't think it's prefix, postfix, circumfix, postcircumfix...
00:17 shdb left
TimToady it's actually classified as a strange infix 00:18
00:18 Actualeyes left
SmokeMachine TimToady: is that what you think about the arrows too? 00:19
liAealneDx that for sure, I was simply saying that it's not new for them to add a normal halfwidth character for stuff that can be written with several characters
TimToady: but yes, I was a bit surprised with your previous answer about ⁇‼ :)
BenGoldberg If it could be overloaded, e.g., our macro duo-infix:<< ⁇ ‼ >>( $cond, $true_part, $false_part ) { .... }, then it could be put into an (optional) module, and we wouldn't be having this argument about it, since it wouldn't be part of core perl6. 00:20
liAealneDx BenGoldberg: I don't think you can easily add it yourself
BenGoldberg Why not?
And, maybe changing perl so that users can add their own multi-infix subs (and macros) is something to look into. 00:22
liAealneDx BenGoldberg: well… I guess adding something into token lambda may be possible, but I'm not sure how to achieve this pblock change: github.com/FCO/rakudo/commit/8d544...cde1fa46ff 00:23
00:23 Cabanossi left
liAealneDx SmokeMachine: -> can actually be autocorrected to → 00:23
and <-> also
libreoffice writer does this, but I'm not quite sure why would anybody have code in it… 00:24
ok, same thing with impress
so yeah, if somebody does a presentation and throws in his code there… that may happen, maybe
00:25 Cabanossi joined
BenGoldberg Some editors autocorrect :) into a unicode smiley. Which makes me feel sorry for anyone using a language which makes use of (: ... :) (not that I know of any, but still) 00:26
samcv ⁇ and ‼ could have been made for transcription purposes
00:26 bwisti left
samcv transcribing written text and not losing content. a lot of random things like ligatures were added for those reasons 00:27
so written text can be transcribed in unicode and not lose data
BenGoldberg Like "Out out‼ You demons of stupidity‼" ?
00:27 shdb joined
TimToady I don't think it's written text, but maybe somebody's legacy character encoding had it for some reason 00:27
samcv could be that too 00:28
liAealneDx m: say ‘‼’.uniprop(‘Emoji’)
camelia True
liAealneDx o-ops…
samcv those are two reasons why something might be included
liAealneDx well now we know…
samcv liAealneDx, that doesn't mean anything
# is Emoji too
liAealneDx m: say ‘#’.uniprop(‘Emoji’)
camelia True
liAealneDx okay, nm
nvm*
IOninja TimToady: there hasn't been a release with ⁇/‼ yet. It's not too late to pull the plug on it :)
samcv heh
liAealneDx looks at his code 00:29
IOninja :D
BenGoldberg Someone could always shoot an emil to the unicode consortium.
s/emil/email/
samcv about what BenGoldberg
BenGoldberg Asking why ‼ was added‼ :)
samcv m: say '‼'.uniprop('Age')
camelia 1.1
samcv well. it's quite old
damn 00:30
liAealneDx ⁇ is newer I think
m: say '⁇'.uniprop('Age')
camelia 3.2
TimToady IOninja: I'm kinda suggesting that we might want to back it out for this release until we know more about those characters and whether anyone else in the whole world is ever going to use them
IOninja TimToady: sounds good.
TimToady and what they use them for, if so 00:31
BenGoldberg . o O ($cond ❓❓ $true ❗❗ $false)
samcv m: '⁇'.ord.base(16)
camelia ( no output )
samcv m: '⁇'.ord.base(16).say
camelia 2047
TimToady already feels a little bad about stealing the half-width corner quotes for "off-brand" use :) 00:32
samcv well there's no annotation in NamesList.txt
TimToady 'course, given how much violence we did to angle-bracket semantics, I suppose that's small potatoes...
SmokeMachine :( 00:33
liAealneDx somebody, somewhere, says “The "double exclamation mark" character ‼ was originally added to help with vertical East Asian and Mongolian text”
samcv TimToady, you mean ｢ ｣ ? what's so bad about that
offbrand? you mean using with the wrong script?
TimToady I just mean overlaying them with Q semantics 00:35
if ⁇ and ‼ were added for vertical East Asian text, then they probably should have been considered square, that is double-wide, characters, and thus indistinguishable from ?? and !! in left-to-right monospace fonts, but obviously they got proportionalized at some point (and differently, in my font, which is part of why they're ugly, and I don't really like 'em aesthetically) 00:37
so really, they're looking more and more like a Unicode botch 00:38
which means we should probably steer clear of them for now
in the absence of any argument to the contrary, I think they fall mostly into the "you think that's cute today" category 00:39
00:39 kaare__ joined
TimToady anyway, if you want someone to blame, you can blame my vacation self for letting my brain fall out temporarily :) 00:40

liAealneDx TimToady: while you're here, what's your opinion on “returns”? Anything changed? 00:52
TimToady: and what about “of”? 00:53
00:53 Cabanossi left 00:55 Cabanossi joined
TimToady if we ever want to move the language in the direction of functors, we want to keep the view that functors are mappings of input types to output types, and I'd like our signatures to reflect that, not divorce return values as an implementation detail because they don't happen to participate in dispatch 00:55
BenGoldberg m: sub foo(-->Str) { 42 }; 00:56
camelia ( no output )
BenGoldberg On a vaguely related note, what do you think of compile-time testing whether the return value of a sub is compatible with what that sub has been declared as returning? 00:58
m: sub foo(-->Str) { 42 }; say foo; 00:59
camelia Type check failed for return value; expected Str but got Int (42)
in sub foo at <tmp> line 1
in block <unit> at <tmp> line 1
BenGoldberg would like that ^ error message at compile time, if possible.
geekosaur "patches gladly accepted", I think :p
BenGoldberg doesn't have the faintest idea how to implement that sort of functionality. 01:10

Todd Hi All! 01:48
yoleaux 14 Mar 2017 05:12Z <samcv> Todd: .basename is there there docs.perl6.org/routine/basename#(I...d_basename
samcv hi Todd added that other thing to the docs that you said wasn't there too
01:48 lukaramu_ left
Todd very sweet. Thank you! 01:49
question on date: I have this example:
perl6 -e 'my $Date=DateTime.now(formatter => { sprintf "%02d-%02d-%02d %02d:%02d:%02d", .month, .day, .year, .hour, .minute, .second }); print "$Date\n"'
Is there one of those fancy .month words to turn the month into the name of the month (January, etc.)? 01:50
samcv i have no knowledge of such a thing 01:51
also those are different in different languages etc.
ok no there is not. i searched the whole source of rakudo and it does not exist 01:52
Todd Then a pre-salted array it will be! 01:53

SmokeMachine what means <.[ - + ? ~ ^ ]>? 02:16
specifically the "."
geekosaur doesn't < > capture by default? 02:20
cf. <ws> (captures) vs. <.ws> (doesn't) 02:21
SmokeMachine geekosaur: but <[a..z]> captures? 02:23
geekosaur I would suspect, since that's what he . usually means 02:24
or it could be someone who made that assumption but it doesn't in that case
SmokeMachine make sense...
another question:
geekosaur m: if ('a . c' ~~ /<[ . ,]>/) { say $/.perl } 02:25
camelia Match.new(ast => Any, list => (), hash => Map.new(()), to => 3, orig => "a . c", from => 2)
SmokeMachine m: say [+] ( 1;10, 2;20, 3,30 ) # <- is that right?
camelia 6
02:25 Possum joined
geekosaur not actual capture, looks like 02:25
m: if ('a . c' ~~ /<.[ . ,]>/) { say $/.perl }
camelia Match.new(ast => Any, list => (), hash => Map.new(()), to => 3, orig => "a . c", from => 2)
SmokeMachine geekosaur: looks the same to me... 02:26
geekosaur that was my point, here it makes no difference but elsewhere it means don;'t capture 02:27
so "superstitious"
m: say [+] ( 1;10, 2;20, 3,30, 9 )
camelia 7
geekosaur that's what I thought :) it's adding the lengths of the sublists 02:28
SmokeMachine m: say [+] ( 1;10, 2;20, 3,30; 5; 5; 5; 5 ) # <- is that right?
camelia 26
SmokeMachine m: say [+] ( 1;10, 2;20, 3,30; 1,2,3,4,5,6,7 ) # <- is that right? 02:29
camelia 13
SmokeMachine should it do that?
geekosaur looks consistent to me, no idea if it is correct 02:30
not sure [+] is even meaningful in that context, but I will guess this is using a behavior we want in other contexts (treating a list as its length in numeric context was recently mentioned on one of the mailing lists) 02:31

liAealneDx SmokeMachine: list stringify with spaces, and you just concat them all together
SmokeMachine im trying to understand this bug: 03:05
liAealneDx SmokeMachine: as for printing from Grammar.nqp, maybe you want --target=parse or --target=ast instead?

liAealneDx ah 03:06
SmokeMachine liAealneDx, MasterDuke thanks!
liAealneDx SmokeMachine: ah, you have an error! Then --target won't help 03:07
geekosaur that strikes me as parser weird based on . handling, unrelated to reduction as such. iirc "^10 .grep" working there is taking advantage of an edge case that doesn't exist in that situation?
liAealneDx SmokeMachine: but --ll-exception probably will 03:08
geekosaur that is, working when typed by itself
03:08 Cabanossi left
SmokeMachine m: say sum ^10 .grep: *.is-prime 03:09
camelia 17
SmokeMachine geekosaur: ^ if it was not related to reduce, would it work? 03:10
03:10 Cabanossi joined
geekosaur I think the point is more that it's an edge case, and one not really reliable 03:11
'^10 .grep' is a hack to avoid parentheses, not intended behavior but taking advantage of an edge case
SmokeMachine geekosaur: with parentheses it does work... 03:12
geekosaur (because otherwise it parses as ^(10.grep: ...)
someone discovered that adding the space just happened to do the right thing in at least some cases
that does not make it an advertised feature

liAealneDx there we have it 03:15
geekosaur and I recall it being made under duress, in part because it would be susceptible to weird behavior at times
03:16 khw left
liAealneDx so it wasn't so much for omitting parens, but for making .= consistent-ish and to allow you to write method calls across many lines 03:16
geekosaur right, that. the omitting parens thing was found afterward as a convenient side effect 03:17

geekosaur actually, looking at this more closely, I suspect it was a thinko 04:17
infix:sym<.> was justified by the existence of metaops, so it got treated as a metaop
I suspect that line could just be removed 04:18
(the other change in that commit is still needed to disallow metaops)
but, that should probably be carefully tested 04:19
unless the metaops all somehow chain off the infix:<.> rule somehow
actually I think they *do* chain off that, and there's no way to distinguish . from a metaop involving . 04:22

11:11 domidumont left
Ven DrForr: I'm not sure what you mean? restocks? 11:12
shifts index by one?
DrForr Heh, I knew I was going to have a problem explaining that. Yes, shifts by one woudl be a better way to put it.
I know it's trivial to do with a variable and a bit of logic, but I thought that there might be an adverb modifier.
Basically have $a be the current iteration, $b be the next. 11:13

Ven that also *could* sound like a reduce()?
DrForr I'll look. 11:14

IOninja tbrowder: I think in this case the problem is the special-casing of `.pick` without a count to return the item instead of the Seq.
Which isn't available in sub form.
|pick 1, @c; is shorter :)

perlpilot: what are you basing that on? 14:20
DrForr Re: the Unicode stuff I'd agree that quite a bit of the reactions are deriding Unicode because it's not SRS BZNS. I usually figure "If I wanted a boring business logic language I'd use Java."
lucs Aww, poor COBOL.
IOninja prefers to stay clear of delusional pep-talk "We're ahead of everyone!" "We're the best" "Perl 6 is the best glue language in the world!"

sena_kun DrForr, thanks! 14:22
El_Che perlpilot: perl6 is certainly one of the nicest languages I've coded in, but getting smug about it is out of place. We don't even have an scalable webserver for REST services.
DrForr It's entirely possible, I have a *lot* of what should be internal classes specified in the Perl6::Parser;;Factory file, and that could be playing silly buggers. 14:23
El_Che DrForr: I hope to test your code soon. Exited about it 14:24
DrForr I'm probably going to add brace styles to the tidier after the weekend - I'm headed to Copenhagen.
El_Che: Nod - There are still some things that are limiting the parser, but I've added some fallback stuff that tries to capture any terms the code doesn't catch in a single "token" that will get separated once someone sends in a bug report :) 14:27

[Coke] I've been using vi since... 1989? was the only option that worked on the mainframe and UNIX 14:41
DrForr One of the important bits is that vi/vim runs on every OS out there, with the possible exception of Mac. (yes, I know about OS X, I was referring to pre-OS X.)
And Windows.
IOninja DrForr: the very first time I used it, yes, I couldn't figure out how to quit. But the one conscious effort to see whether it lives up to its hype lasted 20 seconds with a resounding answer: no

DrEeevil especially when you can communicate in meaningful ways instead

AlexDaniel the argument that twitter renders ‼ as emoji is not a reason though, if at some point it decides to render * as emoji it's not a reason to drop * everywhere

AlexDaniel but again, as I said, it's not about why we shouldn't add ⁇‼, it's other way round 14:47
IOninja AlexDaniel: it's a reason enough as it indicates the ?? and !! don't make a good pair.
DrForr It renders Perl 5 code as emoji too, so that's not a valid excuse.

b2gills .ask TimToady I wonder if we can take a measured approach to removing ‘returns’. We just remove it from all tests in ROAST (from the main branch only) and have it be a non-standard addition to the language that Rakudo has. 16:29
yoleaux b2gills: I'll pass your message to TimToady.
IOninja So for all intents and purposes we'd NOT remove it, except we'd have to document it weirdly and warn users not to use it because it's not standard Perl 6? 16:31
ugexe its more that some fetchers could do an http post and thus implement that functionality trivially (although some can't). I suppose if I implement it for wget and curl that covers most cases though
IOninja Feels like a lot of work for no good benefit.
b2gills We'd punt the final decision to actually deprecate and remove it until there was a second Perl 6 implementation 16:33
timotimo ugexe: oh, OK, that's what "fetcher" means here 16:34
IOninja b2gills: but for what benefit? We may as well punt it until we start implementing whatever TimToady wants implemented that requires us to use `-->` instead of `returns`. And what I see happening with this approach: (a) more people use `returns` so more people need to upgrade when it gets nixed; and (b) we waste human-hours bringing `returns` to support all the return values `-->` supports that `returns` 16:35
currently doesn't.
El_Che lol, normalizing texts and I just met the utf8 '...' thingy in a text 16:36
IOninja b2gills: right now the removal won't happen until 6.e that's years away. I think that's plenty of time.
El_Che (not related, but it made me laugh though)
timotimo you meant …?
El_Che timotimo: please tell me you copy pasted that :)

well, bugglet
bstahlman Ah. Ok. I noticed it works fine outside the block.
IOninja s: False, 'Str'
SourceBaby IOninja, Sauce is at github.com/rakudo/rakudo/blob/e135...Bool.pm#L5
IOninja bstahlman: well, it works fine on an instance of Bool, but not on the type objectt
bstahlman: link to that example? 18:09
bstahlman en.wikibooks.org/wiki/Perl_6_Progr...Structures
lucs Am I doing something wrong, or is the $count argument ignored in todo('NYI', $count) in Test?
bstahlman The Given / When example.
SmokeMachine www.irccloud.com/pastebin/NAY7BI5z/
IOninja m: use Test; &todo.signature.say
camelia (;; Mu | is raw)
IOninja m: use Test; &todo.candidates».signature.say 18:10
camelia (($reason, $count = 1))
IOninja lucs: it's not ignored
lucs I'm doing something wrong then :)
(or it's buggy?)
IOninja lucs: I've not seen the code, so I can't tell! :) 18:11
lucs I'll show you my code...
IOninja And I highly doubt it's buggy, since we use Test for spectest runs
lucs Yeah, I agree.
IOninja bstahlman: a yeah, I see it in the last line. It's a bug in Rakudo that... I hope I can fix shortly :) 18:12
bstahlman IOninja: Thanks. 18:13
lucs Oh, maybe I'm just misunderstanding 'todo'.
Yeah, that's it. Sorry. 18:15
IOninja cool
lucs (I think I wanted 'skip'.)
IOninja todo('NYI', 2); ok 0, 'this is a todo'; ok 0, 'this is also a todo'; ok 1, 'this isnt'
lucs: note that you'll still have to manually avoid executing skipped tests.
bstahlman IOninja: So how would I match a variable that's set to True within a given/when? I'm getting errors or unexpected results with the approaches I've tried.
IOninja if 42 { ok 1; ok 2; ok 3; } else { skip 'cannot test stuff ATM', 3 } 18:16
lucs Aha.
Okay.
bstahlman E.g., True { ... } warns me that I probably want something like ":so" or "*.so".
IOninja bstahlman: first, they are separate constructs: given just aliases the stuff to $_ and when smartmatches against $_; you don't have to use them together. 18:17
bstahlman: and the way to do it is: when :so { say "tis true" }; when :not { say "tis not true" }
That syntax calls .so and .not methods respectively
m: $_ = 42; when :so { say "tis true" }; when :not { say "tis not true" }
camelia tis true
IOninja m: $_ = 0; when :so { say "tis true" }; when :not { say "tis not true" } 18:18
camelia tis not true
bstahlman IOninja: I tried the :so approach and it didn't work until I removed an earlier when that matched on Int.
IOninja bstahlman: Umm.. well, this would evaluate whether the thing is true; it won't check if it's a Bool
18:18 cdg left
bstahlman Is the literal True I was setting the topic to perhaps being coerced to an Int by the "when Int"? 18:18
IOninja bstahlman: block form of `when` shortcurcuits.
bstahlman: and Bool is an Int, so that's why 18:19
IOninja takes another look at that wiki example
yeah, the last case won't ever match
Well, Unless you make your own Bool that isn't an enum :P
bstahlman IOninja: Ah. I guess I wasn't thinking of the Bool as being close to int under the hood the way it is in C for instance. 18:20
IOninja m: given class Bool {} { when Int { say "Int" }; when Bool { say "Bool!" } }
camelia Bool!
IOninja ehehe
m: given True { when Int { say "Int" }; when Bool { say "Bool!" } }
camelia Int
bstahlman IOninja: Thanks for the help. Just starting to play around with p6. I can see I have a lot to learn... ;-) 18:21
IOninja edits the wiki example to test for Bool first
ehehe, my first fix has compilation failures \o/ 18:25
But it wasn't just Str I tried to fix but many other methods

IOninja SmokeMachine: it still needs a test for it. I know the test you fixed tests it indirectly but better to have a proper test (or just add this ticket number in the comment together with the other ticket number in that test) 20:20
Basically if it breaks again people could spot that the issue should be fixed instead of assuming the test is buggy 20:21
Ohhh wait no
The test wasn't crashing before so we *do* need a new test :) 20:22

jnthn Reductions parse just like sub calls, so [+] ... is listop syntax and [+]() is function call syntax 22:30
SmokeMachine without the () the [] is trying to use the string...
geekosaur and this is a bit of an ugly corner case, but a less commonly hit one than the perl 5 version while trying to avoid forcing you to parenthesize every list
SmokeMachine m: use Test; is(([+](^20 .grep: *.is-prime)), 77, "can we use &infix:<.> as argument for []");
camelia ok 1 - can we use &infix:<.> as argument for []
geekosaur (perl 5 took the opposite interpretation, leading to people being surprised by the behavior of e.g. `print (3), 5`)
SmokeMachine m: use Test; is(([+] (^20 .grep: *.is-prime)), 77, "can we use &infix:<.> as argument for []");
camelia ok 1 - can we use &infix:<.> as argument for []

awwaiid My entry for the company NCAA bracket, gist.github.com/awwaiid/32ef1d2110...39546ae055
geekosaur it is annoying, but I find being forced to parenthesize more annoying --- and the perl 5 behavior, when I trip over it, often seems psychotic
I can live with the perl 6 behavior, especially since I always thought the gnu c coding convention of function (params) instead of function(params) to be stupid and misleading 22:33
timotimo but if you want function (params) you can just "use Slang::Tuxic"
