emilbarton hello, I've worked hard to isolate the error I met yesterday. And I come with an 8 lines script that will allow to easily understand my problem with regex match (either : Cannot assign to a readonly var, or Cannot modify an immutable cursor). I've dropped a gist : gist.github.com/emilbarton/7d6671529b0fd6d90423 . Thank you very much for your explanations. 09:29
jnthn sees if he can work out how the weird .new regressions happened

emilbarton moritz no!
ShimmerFairy jnthn: I noticed that nqp::tc() titlecases everything in the string, while Str.tc does just the first character. Come to think of it, nqp's behavior is more consistent, but surprising where I was expecting the current P6 behavior :) 09:31

lizmat so it would seem to me this bug was causing all sorts of other issues as well

Thankfully there's a lot less of them than there used to be :)
lizmat indeed ! 11:32
lizmat goes back to writing Perl 6 Weekly 11:33
nine 16 bit overflow? I thought those times are long gone :)
lizmat let me know if you have anything you think *should* be in there!
FROGGS err, the ctags repo and website state that the project is about maintaining ctags.... but wth is ctags? 11:34
timotimo a collection of name-to-location links, more or less
nine "Ctags is a tool that makes it easy to navigate large source code projects. It provides some of the features that you may be used to using in Eclipse or other IDEs, such as the ability to jump from the current source file to definitions of functions and structures in other files." 11:35
courses.cs.washington.edu/courses/c...ctags.html
jnthn nine: You can easily recreate them by copy-pasto'ing a cast, apparenlty... :)
FROGGS aha
timotimo it lets you "jump to definition" as well as have a list/tree of symbols for the current file

moritz there's no good way 12:34
leont I guess I should first define an AND, and then add the NOT, but I'm not sure that's going to work :-s 12:35
moritz especially if you want to scope the "not in between" somehow
leont Not between "\n| and "..."
... is a valid plain scalar, except on the main scope where it terminates the document -_- 12:36
moritz <!after\n> <token> <!before $>
or since it's valid syntax, but different semantics, you could parse it normally, and make the distinction in the actions 12:37

tony-o m: my %h = a => 123; say %h<b> eqv '';
camelia rakudo-moar dd6c85: OUTPUT«False␤»
tony-o that might be more what you want carlin
lizmat I would argue that %h<b>:v should return Nil
rather than an empty list
masak lizmat: ...why do we have a .take ? :P 14:17
lizmat I have no idea, that was before my time
masak if it's just a sub, not a keyword, people who wanted .take could already do .&take
but .take is probably older even than that realization...
lizmat it *is* being used in the core
masak ok
jnthn masak: @foo.deepmap(*.take) is cute 14:18
Though only 1 char cuter than *.&take :)
masak for some reason, I find it more palatable to stuff the core setting with useful routines than to stuff Mu/Any with useful methods...
I guess because they inherit into *everything*
and we kinda complicate life a little bit for people who felt .take was a nice method name for their API... 14:19

it will always be empty if it gets to the last line, which means there is no candidates 16:54
jnthn Right, but the push to it is gone too?
tony-o it returns directly, like CURLF
jnthn I guess I'm just asking, why "+@candi ?? @candi[0] !! ();" intead of just () ?
tony-o jnthn: i pushed that in there with my spacing fix 16:55
jnthn Will this cause warnings for folks using Panda? 16:56
Since it doesn't pre-comp?
Or does it not use CURLI at all any more?

btyler dha: don't want to do the blogspot login dance, but for me the quality of perl 5's documentation was the omnipresent "SYNOPSIS" section 17:37
was/is, excuse me
dha no worries. I'll take comments here. ;-) 17:38
Thanks.
17:38 pierrot left, pierrot joined
dha That would be in module docs, rather than the perl docs per se, yes? 17:39
btyler for me, a decent synopsis makes up for a lot of other failings; heck, I might not even discover the other documentation failings :)
I suppose, although perldoc -f split has essentially a synopsis in the first 3 lines
17:40 larion left, n0tjack left
dha Ah. That kind of synopsis. Noted. 17:41
btyler you're totally correct, I was thinking module, but both are deeply appreciated
although I think it's fair to say that module docs for modules that ship in the main distribution are almost as important as core language doc
dha Indeed. but different from the point of view of doc writing. 17:42
And, yes, although not labelled "SYNOPSIS" the format examples for functions are important. 17:43
btyler for sure. ok, that's all the input I had, sorry for conflating module doc with core language doc
dha No worries. It's valuable and appreciated.
btyler I just have a deep love for SYNOPSIS culture
dha synopses are good. :-)
btyler it really helps me get stuff done
Juerd found S07 easy to read, except for Iterable section 17:44
Juerd doesn't know what "mark out" means, technically 17:45
The second paragraph can be read as "mark out when .flat is used", or as "flatten when .flat is used"
I'm not sure if "in conjunction with" means "together with", or somehow refers to junctions. 17:46
dha Hm. looking at C<split> in the p6 docs, I'm wondering if maybe we need "synopses" more like the p5 ones, rather than ones that seem to reflect the p6 implementation rather than use.
Juerd The last sentence ends in "returns identity". I don't know what returning identity is, but which identity is returned? 17:47
dha: What's a Perl 5 synopsis?
dha As discussed above. If I understand btyler correctly, stuff like "split /PATTERN/,EXPR,LIMIT" 17:48
btyler I was just shoe-horning the term into a pattern seen in the p5 core docs
Juerd Oh, synopsis as in =head1 SYNOPSIS, not synopsis as in design document. I get it.
17:49 rurban left
dha as opposed to what's in split for p6, e.g. "multi sub split( Str:D $delimiter, Str:D $input, $limit = Inf, :$all) returns Positional" 17:49
17:49 domidumont joined
Juerd I quite like having the signature in the documentation 17:49
dha Of course, because there are several C<split>s, this gets complicated.
btyler I'd also note an anti-pattern in the python core docs: I used python for two years in university and pretty much had no idea what the docs meant by "kwargs" everywhere
PerlJam dha: since types have a more prominent role in P6 and multis exist, I think having the full signature is quite useful
btyler of course, once you know it, it is very clear
dha Juerd - I should have said "along with" rather than "rather than"
Juerd btyler: Have you found out whether kwargs are edible?
btyler nom nom nom 17:50
PerlJam dha: that's not to say there shouldn't *also* be here's-how-to-use-the-thing synopses
dha PerlJam - right.
btyler *had no idea what 'kwargs' meant, despite referring to the online docs constantly while working through my assignments 17:51
dha With some exceptions, I'm thinking that more information is generally better.
PerlJam yep
17:51 AlexDani` joined
Juerd PerlJam: When examples are included, I love when there's a basic one and a more advanced one. A lot of documentation uses examples to show off capabilities, rather than the simplicity of the most common usage. 17:51
17:51 AlexDani` is now known as AlexDaniel
btyler which generalizes to "be really careful of the amount of language-specific vocabulary you ask people to pick up while reading doc" 17:51
Juerd (Referring to documentation in general, not Perl docs specifically)
PerlJam Juerd: indeed. I find it annoying when examples try to show-off everything at once. 17:52
Juerd btyler: Wiki-style links can be useful. They allow you to use jargon for conciseness without the downside of having many people miss out.
AlexDaniel How can I search for all bug reports that were opened by me? Both open and closed, I want to review a couple of them… 17:53
Juerd PerlJam: I like it when they do, but not as the *only* example :)
dha Juerd - I agree. I'm thinking, in general terms, (full signature synopsis)/(usage synopsis)/(description with appropriate examples interleaved)
PerlJam dha++ sounds awesome
Juerd dha: That would work. Personally I'm not a big fan of interleaving because it gets messy, but I wouldn't object to it.
btyler Juerd: yes, certainly, although man page formatting precludes taking too much advantage of links 17:54
dha Well, when I say interleaving, I mean "here's what this does (...) like this: (example)
Juerd I think that probably most people like the interleaved style.
dha which might be what you don't like, but I think it's generally useful.
Juerd btyler: I think that primarily advanced users who have previously studied the language and learned the jargon will use manpages, whereas most beginners will very probably (only) use HTML resources instead. 17:55
btyler yeah, perhaps. I used them a lot when I was learning perl, if only because it was faster than navigating my browser to the appropriate web version, but I guess I don't know how common that learning scenario is 17:56
PerlJam I know that when I must use PHP, php.net is a necessary resource ;) 17:58
dha Juerd - I wouldn't assume that. Particularly for p5 programmers who are probably pretty used to using "perldoc perlblah" or "perldoc -f function"
Juerd I've been called a fossil for using those. 17:59
dha I would not call you that for that. :-) 18:01
Of course I would call people who called you that young whippersnappers and tell them to get off my lawn, so maybe I'm a bit out of touch. ;-) 18:03
pink_mist prefers reading the perl5 perldocs online most of the time; the browser has a more featureful interface for navigating around the docs than my terminal has
dha Young whippersnapper. Get off my lawn! 18:04
Juerd :)

Juerd www.urbandictionary.com/define.php?...=pink+mist
pink_mist Juerd: it's not from ud :/
dha looking things up in Urban Dictionary is usually a mistake. :-)
pink_mist Juerd: though I guess it's not far from it ...
Juerd dha: I didn't specifically look it up there. Duckduckgo found it for me.
dha btyler - or mirrored on something other than blogger?
pink_mist Juerd: heh, not really ... I got it by being uppity towards an operator in some other channel, long long ago, on a network far far away ... and he got annoyed at me and killed me so hard a pink mist was all that was left
Juerd Heh 18:10
dha Juerd - even so. :-)
PerlJam pink_mist: here I've been thinking that you have some affinity for bombs/bomb squads 18:11
pink_mist 0_o lol
Juerd I thought maybe it had to do with "My Little Pony" or something like that :)
pink_mist no no, that's just my hostname (uhm, if I'm uncloaked that is) :P 18:12
PerlJam Juerd: that's a far happier version of things :)
btyler dha: I'm just being a grouch about blog comment systems, don't sweat it 18:13

DrForr Damnit, we're woking on it, it just got delayed due to a failed gravity check.

DrForr No, I spontaneously decided to make sure gravity still worked by moving a limb wrong. 18:15
dha ow. 18:16
But thanks for checking. 18:17
DrForr Hence being hospitalized in Granada for ~2 weeks.
You're quite welcome, gotta keep an eye on that bastard.

dammit autocorrect. reinJURED.
DrForr Oh, that. No, still the original injuries. 18:18
dha Yeah, now that Isaac Newton's dead, we all need to pitch in.
18:18 vendethiel joined
dha back to original comment, what delay are you referring to? 18:18
DrForr On revamping blogs.perl.org - I saw teh comment on blogger, thought that might be what you're referring to. 18:19
dha oh, no. btyler just had a comment on my last post at dhaperl6.blogspot.com and preferred not to sign in to comment on it. 18:21
no mention of blogs.perl.org. UNTIL NOW.
:-) 18:22
Although maybe I should mirror there.
Speaking of full signatures... I'm seeing things like "Str:D" and "Str:D:" What are all those Ds and colons doing? 18:25
pink_mist I think it's something to do with 'defined'
but I'm unsure
dha ok. Now we're both unsure. ;_) 18:26
FROGGS Str:D $foo - specifies a parameter that accepts a Str instance
Str:D: $self - specifies that the method can only be called on a Str instance
dha and the D means... ? 18:27
FROGGS defined
pink_mist so what precisely is the difference between 'Str $foo' and 'Str:D $foo'?
... =)
18:27 mohij joined
FROGGS Str $foo also accepts an undefined Str, the type object itself 18:27
dha Aha. Ok, now I'm convinced we really need usage synopses (or whatever we would call them) as well as full sig synopses. 18:28
pink_mist what is the ':D' construct in that called? why ':' and why 'D'? well ok, I guess I understand the D
18:28 patrickz left
dha because anyone coming to p6 for the first time is going to look at that, shake their head, and go away. 18:29
FROGGS pink_mist: a :foo is called a colonpair
pink_mist: we often use these to attach information to things
pink_mist humm, so the :D colonpair is a predefined one I take it? can one create ones own colonpairs? what colonpairs already exist? 18:31
TimToady it's obviously a smiley
Juerd :D is probably the ugliest commonly used thing in Perl 6
pink_mist hehe
TimToady so it only accepts happy values 18:32
Juerd TimToady: I can't parse it as a smiley because it has no whitespace in front of it :)
dha Juerd - I've been around perl long enough that I do not believe that. :-)

Juerd dha: What other Perl 6 is ugly like it, then? :) 18:33
dha Oh, I have no idea. I just don't think that's anywhere near ugly enough to be a winner. :-)
moritz finds character clsses in reexes too verbose
Juerd Most of the language is so beautiful. Unlike Perl 5, with its $foo->$#* :)
moritz <[a..z]> vs. [a-z]
Juerd moritz: That was my #1 ugly thing until :D came along, because :D is used much more often 18:34
PerlJam has never used :D except in setting code.
Juerd I wonder if :D is the ASCII equivalent of ☺
(And if ☺ is equally valid.) 18:35
I could so have a sub foo (Str☺ $bar) { ... }
FROGGS no :o)
moritz sometimes I wonder if the :D could be implicit for all methods that access an attribute
Juerd I can even think of why it had to be :D instead of :)
moritz: method:D ;) 18:36
FROGGS .oO( metho:D )
Juerd Haha
What's metho☺, though? :) 18:37
pink_mist what about metho☻ :P
Juerd pink_mist: Potato, potato :) 18:38
AlexDaniel Hm. How can I search for all bug reports that were opened by me? Both open and closed, I want to review a couple of them… 18:39
dha Is :D used in the actual language typically? Or just in implementation/definition?

Juerd dha: Scrolling through my Perl 5 code, I think I would use :D a lot in Perl 6.
dha Oh? How so?
Juerd I have quite a lot of "defined" checks, including "// die".
And then there's a lot of code that probably should have those checks, but doesn't have them. 18:41
AlexDaniel yes, because :D is not there
18:41 pnu joined
AlexDaniel Juerd: I agree 18:41
dha Ah. you'd do that rather than doing something like "is defined"? Of course, I'm not actually using my brain at the moment, so that may be complete garbage.
mr_ron is the no-such-rule problem a bug?
Juerd dha: I like how :D is very short. I just don't like the way it looks. I have no suggestion for changing it. 18:42

dalek kudo/nom: 59b5a4b | TimToady++ | src/core/Range.pm:
allow shifting and scaling of Range values

Since it's actually kind of difficult to do correctly otherwise and maintain endpoint exclusions, we now allow basic arithmetic operations on a Range to clone the Range and modify the endpoints in order to shift an interval arithmetically or expand/contract it geometrically.		 21:48

ilmari how long does it take from a commit to land until camelia runs it?
TimToady depends on where in the hour it is, but I expect this one in about half an hour 21:58
maybe 15 minutes
er, 25, I mean
21:58 pierrot joined
TimToady starts recompile at 7 after the hour, and usually takes til about 20 after or so 21:59
(last I knew)
timotimo huh, so if it's a range it won't turn into a number any more when used with arithmetic operations? 22:00
lizmat timotimo: wrt to the .min / .max optimisation: are there a large number of numbers involved? 22:01
timotimo: maybe an approach that wouldn't reify all the values in one go would be better ? 22:02
TimToady timotimo: it still numifies the same
timotimo 9 values in my case
TimToady: yeah, but not with infix + and - apparently
TimToady the situation never arose in the test suite, as a data point

TimToady one of those things you might write in a repl but almost never in real code 22:05
22:06 lizmat left
timotimo a big performance penalty in my code arises from the way i grab neighbouring fields in my 2d array 22:06
22:06 lizmat_ is now known as lizmat
timotimo i just index into values located "outside" the array and catch that with // Inf 22:07
because .min will make the Inf "disappear"
lizmat timotimo: do you use a slice?
timotimo i do not
lizmat AT-POS instead of [] ?
timotimo no
lizmat you could try that
timotimo i write it like that because it looks a bit less bleh :)
the problem really is that it throws the exception and i resolve it with //
at least it causes deoptimizations 22:08
lizmat timotimo: in the past (long, long ago, when writing a dungeon game) I resolved this by actually having out of bounds elements with a value 22:11
that would indicate border in a dispatch table
timotimo yes, that's a very common way to do this kind of thing
add 2 to each dimension and index with 1
er, i mean: starting with 1
lizmat yup, something like that
timotimo the worst thing for this program is that it leaks something that is tracked by the garbage collector and ends up with a gen2 root put in place for it 22:12
the garbage collection time rises steadily
i've had it reach 100ms after perhaps a minute of execution
hm. i'm actually quite curious to see how the performance changes when i remove all SDL2 stuff from that 22:13
lizmat gnight, #perl6!

timotimo pff, are you making fun of my ability to say more than just one thing? 22:20
