ssutch yeah 00:02
force of habit (python,ruby,js)
masak yes, the rule is this: if you use the '@' sigil, you already have an array for free. 00:03
r: say my @a = 1, 2, 3
camelia rakudo b4d858: OUTPUT«1 2 3␤»
ssutch yeah
masak r: my $s = 1, 2, 3; say $s
camelia rakudo b4d858: OUTPUT«WARNINGS:␤Useless use of "," in expression "my $s = 1, 2, 3" in sink context (line 1)␤1␤»
ssutch is there any copying going on there? 00:04
masak in what sense?
r: my @a = 1..3; my @b = @a; say @a === @b; say @a eqv @b
camelia rakudo b4d858: OUTPUT«False␤True␤»
ssutch if i say my @list = %hash{'list_item'} it doesn't do any copying
what if it has to coerce say, a parcel? 00:05
r: my @a = 1..3; my @b = @a; push @b, 4; say @a === @b; say @a eqv @b
camelia rakudo b4d858: OUTPUT«False␤False␤»
masak r: my %hash = list_item => [1, 2, 3]; my @list = %hash<list_item>; say @list === %hash<list_item> 00:06
camelia rakudo b4d858: OUTPUT«False␤»
masak looks like copying to me.
ssutch yeah
masak r: my %hash = list_item => [1, 2, 3]; my @list := %hash<list_item>; say @list === %hash<list_item>
camelia rakudo b4d858: OUTPUT«True␤»
masak use binding if you don't want a fresh copy :)
ssutch ah
so @liast stays a parcel in that case 00:09
@list
is it possible to get an element from an array, defaulting to some value if it doesn't exist? like @arr.some(0, 'alternative') 00:14
timotimo @arr[10] // "yarr!" 00:15

timotimo sprinkles the code with debug statements and sadness 01:01
ssutch hah
why wouldn't your patch be accepted?
timotimo it's a big amount of changes and they don't look good 01:02
it's kind of disorganized at the moment and touches all the places
ssutch my significant other would describe me the same way 01:04
timotimo in that case it's adorable, in my case it's ... frustrating
ssutch break it up into small, palatable changes? 01:05
timotimo oooh, i think i see where i went wrong
wow, that was not a mistake a smart person would have made
benabik Clever people make clever mistakes. 01:07
colomon Clever people sometimes make the biggest mistakes... 01:08
timotimo basically there was a token looking like { something something || <.typed panic> }, i added an assertion at the beginning of something something hoping it'd skip the block
instead it skipped right into the typed panic every time
even worse. i apparently misread that whole thing and it was fine before. also didn't make my code work magically 01:09
01:09 cooper joined
timotimo i hope that once i can make it work i can refactor most of the changes 01:12

ssutch when dynamically generating classes, if i want it to descend from ann object, i should use $type.HOW.mixin($type, Class::A, Class::B) 01:21
does that seem right?

i don't get it. i get an exception, but a closure i put before it isn't being run 01:25
i think i'm getting tireder and the code isn't getting righter. i should probably head to bed. 01:28

sorear ssutch: I promise you, everything which can be done with classes using eval can also be done with the MOP 03:49
ssutch sorear: that's good, i'd rather do things that way
this is how im doing it right now, but haven't yet figured out how to use MOP to generate a class which descends from another class: github.com/samuraisam/p6-pb/blob/6...nerator.pm 03:52
regardless, it's probably more "correct" to use roles anyway, which ClassHOW.add_role($cls, $role) seems to work 03:53

sorear ssutch: can you paste the code which is supposed to add a parent but doesn't work? 04:01
ssutch sorear: im not sure what to do, i tried saying $type is $parent; - that didn't work 04:02
sorear ssutch: I suggest looking at the definition of is 04:04
search the setting for trait_mod:<is>
ssutch sorear: that makes sense :)
sorear generally speaking metamodel stuff involves lots of uppercase letters, especially H and W... 04:06
ssutch derp, the role was in Metamodel::MultipleInheritance 04:15
$typ.add_parent($typ,$parent) # DOH! 04:17
and it works!
now if only i could make namespaces at runtime, i'd be rich!

colomon \o
sorear hrm. I made a small change to rakudo and I worry I may have caused an optimizer regression 10:13
because it made the setting marginally *bigger*, and I think that change should only have been capable of causing shrinkage
FROGGS_ sorear: that could be my patch too 10:15
sorear FROGGS_: I think I pulled and measured after yours 10:16
FROGGS_ before my object-flush patch the setting.bpc was 17meg, afterwards 18meg
sorear so the "big method" in the output from rx.t was causing the method splitter fits
~100,000 instructions, 2018 local variables
200M (insn,variable) pairs needing type deduction 10:17
i made some changes to nqp&rakudo which have the same method down to 25 locals (near-same insn count)
unfortunately, it doesn't verify. 10:18
jnthn 2018 to 25? Whoa. :) 10:19
sorear++
sorear: I may be able to guess if I see the patch, or alternatively I may have no clue.
sorear jnthn: also, the splitter was having a bit of trouble with the splitting. 2018 locals doesn't leave much room after the save epilogue/restore prologue :) 10:20
huh, nqp passes tests and rakudo passes coretests
jnthn right :)
sorear isn't sure how to square this with the new verifier rejecting output 10:21

Add a local_lifetime hint op

This tells the code generator that the named locals don't need to escape the scope of the op. Note that this is more than just a scope analysis, since it affects behavior in loops: you're telling the codegen that it's OK to clobber the named variable between iterations. As such, to automatically generate it would require a dataflow analysis. A future dataflow analyzer might do so.		 10:48

sorear the rx.jast:qb_1 now has 25 locals and 89075 instructions, and the autosplitter identifies seven fragments it could be broken into 11:09
jnthn \o/ 11:10
sorear next: extend autosplitter to actually generate said fragments, and the glue code
FROGGS_ that sounds pretty cool
jnthn That'll win us some tests. 11:11
In fact, with all the test files this manages to pull it, it may be enough to push us into the 80%s

sorear I'm not. :p
jnthn Don't worry, we'll reach the 90%s soon after :P 11:15
masak was the autosplitter written out of necessity (as in "this code won't run otherwise") or was it more of a performance thing? 11:16
jnthn nec 11:18
sorear right now the biggest test files die with "Method code too large!" 11:19
kind of annoying. 11:20
jnthn Indeed...especially as a bunch of them are regex ones, and the regex engine is already powerful enough to parse Perl 6, so it should be able to pass a good number of them. 11:29

timotimo is there some trick to tell backtracking "be eager until you find this token, then see if you can advance, but if you can't, become eager again"? 12:16
if not, no problem, i suppose i can do nongreedy forward search instead 12:17
jnthn "keep going until we can match the next token" is basically what frugal quantifiers are doing 12:21
timotimo is there a speed enhancement to going greedy until a specific token that in many but not all cases signifies that parsing should end anyway is found? 12:24
i think i made the pod parsing significantly slower :| 12:27
i wonder if it'll finish. 12:28
all it's doing is eat more and more memory, so ... i guess something is happening? 12:31
FROGGS_ if it is perl6 code you could use the debugger 12:32
(which makes it even slower :P)
timotimo no, it's in the Grammar again :| 12:33
it's almost constant at 2.4gb now
i wonder if i could try develop this atop jvm? it would certainly be a bit faster to compile.
but i don't know if i can install Pod::To::HTML there? 12:34
if and how.
FROGGS_ no idea 12:35
can you show a diff?
timotimo oh, since it's a crazy slowdown, i could perhaps get away with not turning it into HTML at all
gist.github.com/timo/d7018f9f3f75321bc9b7 - this is my diff
especially note how it removes the <!before '>'> from the content section 12:36
the +? was after the ] in my last try, too.
FROGGS_ typo: end-teg
last added line
timotimo whoops! 12:37
wow.
that would certainly kill it :)
thanks, i needed that second pair of eyes :)
FROGGS_ :o) 12:38
12:38 p5eval joined
FROGGS_ btw, you could add a param to token pod_string_character like: pod_string_character($*POD_IN_FORMATTINGCODE = 1), and then pass 1 on line 12 and 15 12:40
this way you dont need to set the dynvar in line 11, 13 and 15
timotimo don't i need to pass that around everywhere in that case?
FROGGS_ no 12:41
ohh, the signature should be pod_string_character($*POD_IN_FORMATTINGCODE = 0)
timotimo sounds good. i'll finish my test cycle first.
FROGGS_ of course
timotimo ah, it'll stay a dynamic variable in that case?
sounds useful, thanks!
FROGGS_ no premature optimization please :o)
yes
seen it somewhere in the grammar
timotimo about to see my results :) 12:42

mls Hi! 12:47
JimmyZ hello
12:47 konundra joined
mls here's my first try to get rid of the priorInvokation element: gist.github.com/mlschroe/5867111 12:48
timotimo i think i just need to add handling so that C<...> will not cause formattingcodes inside to be parsed 12:50
jnthn commute & 12:52
mls all nqp testcases pass, but I'm not happy about the somewhat "sprinkled" captureouter calls. jnthn++ probably knows a much better place to do it.
FROGGS_ timotimo: is C<...> a separate token?
mls argh, missed him ;)
I'll retry in an hour or so ;)
timotimo no, it's not 12:53
FROGGS_ hmmm, maybe it makes sense to treat pod formatting like q and qq ? 12:54
timotimo i don't know exactly how that's being done
at least there's a range of parameters that defines what gets parsed inside blocks and what doesn't
you can give a =code block an :allows with any subset of the letters A through Z
FROGGS_ you have a nibbler, and roles like q and qq, and depending on what you want to parse you mixin the right rule 12:55
timotimo at least i know now why the output of Damian Conway <L<C<damian@conway.org>|mailto:damian@conway.org>> looks bugged with my changes:
because the input is bugged!
there's no reason for pod to put that second > outside of the L<...>
FROGGS_ yeah
timotimo but now that i've made these changes, i can just use « instead of <
do you think i can make these changes to the docs before the changes to rakudo are merged? 12:56
FROGGS_ these A..Z allow letter sounds pretty much the the quote rules
if you fix the doc, yes
timotimo the docs will renderfail in the non-fixed version of rakudo, though 12:57
FROGGS_ ohhh, hmmm
then I would wait
timotimo it seems like there's another b0rkedness still ... 12:58
FROGGS_ :/
timotimo found the problem! :) 12:59
FROGGS_ \o/
timotimo anyway. yesterday i experimented with different ways to make these letter combinations work and figured out that a single integer as a bitfield is the most workable solution
a list of ones is easier to access, but passing that list on through the dynamic variables made me bang my head on the table a few times too often 13:00
integers are nice, they are kind of atomic, immutable, singlets ... what's not to like?

cognominal I have a question. How SO5 PEG rules applies when a rule is not left anchored. Can a longest string match can win over a shorter one if its start position is greater than the short string? 14:28
timotimo ah, Term::ANSIColor breaks it apparently 14:29
moritz_ cognominal: no
cognominal: left-most match is more important than longest token
cognominal so that should be rule 0 in github.com/perl6/specs/blob/master...ex.pod#L45 ?
moritz_ ? 14:30
moritz_ not really, it applies well before the pecking order mentioned there
it's not an ambiguous parse
cognominal Depends on the defenition of ambiguous parse :) 14:31
timotimo is the definition of ambiguous parse ambiguous? 14:32
cognominal timotimo: I am not sure it is even given anywhere
My initial question was falsely naive. I was almost sure about the answer but in a spec so called obvious things must be stated explicitely. 14:35

hoelzro could other people +1 my PR for pygments.rb? github.com/tmm1/pygments.rb/pull/73 14:36
cognominal I understand that historically synopses build on Perl 5 knowledge by difference but eventually synopses must be self contained.
hoelzro the author decided to rear his head yesterday, and I don't want him to continue to ignore it.
cognominal hoelrzro, is there examples of docs usings your pygment lexer ? we can't just blindly +1 it. 14:39
hoelzro cognominal: you use it just like any other pygments lexer 14:40
you just provide language = 'perl6' 14:41
JimmyZ we had a js highlighter for perl6, fyi
hoelzro I wrote a Perl 6 highlighter for pygments so that Perl 6 code may be highlighted on GitHub
it's in the main pygments (python) repo already, but getting it into pygments.rb is the next step towards GH citizenship 14:42

[Coke] is the autosplitter java only?

[Coke] timotimo: if it's java, you didn't lose much time!
hoelzro FROGGS_: hmm...that brings up a great point. I don't think the highlighter handles that *at all*
timotimo nope, it's on parrot.
FROGGS_ hoelzro: nvm, I dont think that this is a common case within the next one or two years 14:54
hoelzro it's good to prepare for, though
FROGGS_ timotimo: the autosplitter is on parrot? sure? 14:55
hoelzro: having it pluggable like the slangs would make sense (use COBOL)
hoelzro looks at slang docs 14:56

FROGGS_: why are we thinking about the autosplitter?
this is for my pod work ;)
cognominal btw, I am not sure that pygment has a css class for interpolation in strings
FROGGS_ timotimo: that was [Coke]++'s question
timotimo oh
anyway, i've already reached S32 14:58
cognominal hoelzro: I want you to succeed doing hilighting but I am not sure pygment is the tool for that.
FROGGS_ I am a lvl86 dwarf
hoelzro cognominal: hoelz.ro/files/perl6-pygments4.png
cognominal hoelzro, Perl 6 is so challenging.
hoelzro keep in mind that the pygments standard is not to highlight interpolated vars 14:59
the Perl 5 lexer does this as well
FROGGS_ hoelzro++
hoelzro oh, I know P6 is challenging. It took me a long time to "perfect" the lexer
cognominal hoelzro, that's my point
hoelzro but I feel pretty good about its state
FROGGS_ does it handle heredocs as parts of sub calls too? 15:00
hoelzro let's see
cognominal hoelzro. is it able to recognize the end of the heredoc?
hoelzro yes
timotimo cognominal: if we want syntax highlighting on github, there is no other way than to make a pygments highlighter. 15:01
i'm pretty sure github will not let us deploy a perl6-to-js-translated STD.pm6.js for our niche language.

cognominal you are welcome.

timotimo because i'm pretty sure if you want to have C<boo> inside a V<...>, you'll just use V<< >> instead or V« » (and this test just used it that way because <<... and « were NYI) 15:05
cognominal hoelzro, sorry about my Saint Thomas attitude 15:06
hoelzro it's cool
my solicitation was kind of out of context =)
benabik would think that whatever brace you use for the V should be balanced or non-existant inside it.

timotimo so ... inside <<, only sequences of << have to be balanced, right? 15:59
and inside « » any sequence of < and > may appear, balanced or otherwise 16:00
but if i have I«C<<< ... >>>», inside the C, there can only be imbalanced < and <<, but not <<<?
so it only goes "a level deep" if there's a new formatting code?

(but still there are mistakes)
sorear timotimo: it chops the function into segments, then modifies each segment so that at each external jump, it generates code to save and restore local variables to an Object[] 22:47
the verifier is needed to get the types so that the correct casts can be generated in the restore
timotimo yeah 22:48
