Zoffix Man, I'm surprised my postfix:<++> optimization actually comes out 25% slower. I'm binding to a temp local var and rewriting the op to prefix:<++>: temp.perl6.party/pre.html 02:10
At worst, I expected it to be equal. 02:11
And here are the Int candidates my bench is hitting. The postfix one defines a lexical var (I'm guessing gets lowered to local) github.com/rakudo/rakudo/blob/052a...#L212-L222 02:12
Wonder why it's slower

Zoffix MasterDuke: not really. Though for some reason there are 10000029 calls to infix:<+> in my slower version and 10000019 calls to infix:<+> in the faster version.... why it isn't the same or 10000000 calls... I dunno 02:25

camelia 2.50181834
Zoffix Even without my optimization business prefix ++ somehow ends up being slower than postfix. dafuq? 02:27

ZofBot Zoffix, But, Joe, you mustn't stand in the way of her marrying the man she's in love with
AlexDaniel Zoffix: I am a pm reader :D
saramaebee in PMs ;)
AlexDaniel no evals in pms so had to move here :) 02:40
AlexDaniel wishes he was a mind writer
saramaebee on the bright side, you've forced me to learn about regex, which is something ive been putting off for months now 02:41
Zoffix MasterDuke: damn yeah :( And my "optimization" makes it 30% slower even in void context 02:42
AlexDaniel saramaebee: forced is a strong word :)
saramaebee :P
for me to figure out what the hell was going on, i had to. otherwise there's no way i'd be able to use it 02:43
MasterDuke Zoffix: just looked at a profile, { $i++; $z = 1 + $i } has an extra 10000000 sink calls

Zoffix Filed as R#1491 02:43
synopsebot R#1491 [open]: github.com/rakudo/rakudo/issues/1491 [perf][weird] Non-void $i++ is somehow 13% faster than ++$i
Zoffix MasterDuke: and yet it comes out faster? 02:44
MasterDuke no, it's slower
Zoffix Above it's faster
The one I was measuring has same amount of sink calls in both versions; 38 02:45
MasterDuke ? 3.9s for prefix in void vs 2.5 for prefix not in void
m: my $i = 1; my $z; { for ^10000_000 { ++$i; $z = 1 + $i }; say now - ENTER now } 02:46

Zoffix Ah. I was talking about $++ vs ++$
camelia 2.4679179
MasterDuke right, that's the same. postfix in void is faster than prefix in void

SourceBaby Zoffix, Sauce is at github.com/rakudo/rakudo/blob/052a.../Mu.pm#L13
Zoffix Wonder how to make those calls not be calls at all 02:48
02:48 mcmillhj left
MasterDuke can the static optimizer see that a call has no body and just remove it? 02:52
Zoffix As far as I know, it can't look at method calls at all. 02:53
I could mix in a different Mu.sink at runtime and if it removed the call, the code becomes broken

Zoffix ZzZombo: Int:D is a DefiniteHOW object, hence the error you were getting. I think it can be made to DWIMM. I opened R#1493 10:38

Zoffix ZzZombo: as for IntStr, it's from the `< ... >` angle brackets. They create allomorphs for anything that looks like numbers. You can hyper it like `<42 5>».Numeric` to force Numeric portion only and I think there was a shorter way to do that too 10:39

jnthn Yeah but
That doesn't tell you what was in there in the first place :P
The point I was going to try and make was that the type constraint of a Scalar and its default value don't need to be the same
Zoffix Ah 10:41
jnthn So an Int:D decl should probably make the constraint be Int:D and the default value be Int
Because the latter is what is used for the .= call
This is the same mechanism by which every Scalar without a type has a type constraint of Mu, but a default value of Any

tyil Zoffix: is there a way to ignore other nicks/hostmasks in IRC::Client yet? There's another bot in my channel, and I'd like my bot to ignore it 11:12

Zoffix tyil: it's job for a plugin IMO. Here's how I do it in ZofBot: github.com/zoffixznet/perl6-ZofBot...reList.pm6 11:13
This portion in particular: github.com/zoffixznet/perl6-ZofBot...pm6#L7-L15 11:14
An early plugin that matches messages from Ignored users with empty action body so the messages just get consumed and never get to any other plugins
tyil oh, that's pretty neat tbh 11:15
thanks
jnthn Zoffix: Yes, I'd expect so 11:20
Zoffix: With luck it'll fall out of the same fix for Scalar, since the Mu/Any distinction applies to Array/Hash too 11:21

Zoffix There were different places to stick the fix in for Array/Hash 11:22
jnthn ah, ok. Maybe time for some factoring out? 11:23
Zoffix I stuck a "is a definite how? then use .^base_type" over here: github.com/rakudo/rakudo/blob/mast....nqp#L1733 and for hashes it goes here: github.com/rakudo/rakudo/blob/mast....nqp#L1692 and for arrays here: github.com/rakudo/rakudo/blob/mast....nqp#L1625 11:24
seeing some failing spectests, so I guess that ain't the right fix :) 11:25
Gotta go now, but will try again in the evening

Zoffix ZzZombo: note that `where` clauses come with a caveat that side-effects are not supported. If you try to have them (like `state` variables), you get to keep all the pieces. 15:38
15:40 mcmillhj joined
Zoffix There are also some bugs with `state` vars: RT#131542 RT#130257 RT#129817 RT#102994 15:41
synopsebot RT#131542 [new]: rt.perl.org/Ticket/Display.html?id=131542 [BUG] `state` variables unset if multi candidate uses named params

RT#102994 [open]: rt.perl.org/Ticket/Display.html?id=102994 [BUG] State variables are never initialized if the first call of the containing block does not reach them
ZzZombo I want some kind of a value like Nil but the one that will not violate the defined constraint, actually. What I was doing was rather to mess around. 15:44
15:45 mcmillhj left
Zoffix m: my $true-nil := Nil.Mu::new; say $true-nil ~~ Mu:D; my $foo is default(42) = 100; $foo = $true-nil; say $foo 15:46
camelia True
42
ZzZombo So I could say `has Str:D $!name=<the value>` and if the user doesn't supply it, an attempt to do anything but the most basic things like calling `.Bool` on it will cause an exception.
And then, I'd like to allow this value being set only once, but that's optional. 15:47
I see that can't be done easily.

tbrowder hi #perl6 20:37
i'm having problems with a grammar for what i think is a fairly common type of input data file: key/data pairs with comments, blank lines, and empty data fields allowed. i just filed doc GH issue #1759 with an example of the type of input i'm talking about. 20:40
the current example in docs.perl6.org/language/grammars.pod6 is almost the desired format, but it doesn't have the looser format i described in the issue. 20:42
