grondilu hello 00:26
with a module like 'unit module Foo; our @some-really-big-array = do {...};' if I import Foo without actually using @some-really-big-array, will that array be loaded in memory? 00:27
TimToady the mainline of a module gets run once on first use (though after INIT time, iirc) 00:33
so yes, it'll be loaded 00:34
unless the do returns something that .is-lazy

dataangel When am I required to use parentheses when calling a function and when do I not need to? 01:03
01:04 pierre_ left 01:06 cyphase joined 01:07 pierre_ joined
TimToady you need to use parens if there is ambiguity with a reserved word (the reserved word will require whitespace, in that case) 01:08
m: sub if ($x) { say "Interface is $x" }; if('impressive') 01:09
camelia rakudo-moar ef98f8: OUTPUT«Interface is impressive␤»

TimToady other than that, when you mention a noun like &foo, it will not be called unless you use explicit parens 01:10
m: say &infix:<+>

camelia rakudo-moar ef98f8: OUTPUT«0␤»
dataangel TimToady: with-suffix($target, ".cpp") # works like this but does not work with spaces... Don't think reserved words are an issue here though. Just a normal function that takes two arguments 01:11

dataangel I still need to , ?

AlexDaniel sure 01:12
dataangel Mistakenly thought it was like Haskell
01:12 pierre_ joined
dataangel oops 01:12
TimToady perl almost never allows two terms in a row
so args need commas 01:13
AlexDaniel dataangel: by the way, note that when calling a method you can omit parens, but you will need :
m: say 42.base(2)
camelia rakudo-moar ef98f8: OUTPUT«101010␤»
AlexDaniel m: say 42.base: 2
camelia rakudo-moar ef98f8: OUTPUT«101010␤»

MasterDuke AlexDaniel: hot damn! very nice 01:15
re tests 01:16
TimToady yes, methods default to no args (since they already have an invocant, and are often used to access attributes as if they were variables) 01:17
dataangel What is the right way to combine paths, like os.path.join in python? 01:25
Nevermind just found it :p
Didn't expect the name child
MasterDuke there's also join, catfile, catdir, and catpath 01:29

dataangel I have two sets that each have the same and only one element, "bin/editor.o".IO. When I use the (|)= operator to combine them, I expect the left-hand side of the assignment to stay the same since the sets are identical... But instead the set grows another copy every time. Why is that? 01:42

TimToady there you go 01:49
.IO is being some kind of constructor
dataangel Sure
TimToady dinner &
dataangel But how do you get a set that is actually a set then?
I usually care about value equivalence not whether something under the hood shares the same memory address 01:50
TimToady in OO, different objects are different values even if they happen to have the same innards 01:51
so don't call .IO if you don't want that
01:52 cyphase left
TimToady it has to be that way for mutable objects to exist; don't use mutable objects as if they were FP objects, is all... 01:52
dinner really & :)
dataangel TimToady: I've been doing OO in C++ for years with value equivalence. Everything is an object in python too and doesn't have this behavior either.

BenGoldberg dataangel, ^ is that what you want? 01:59
dataangel BenGoldberg: yes but that only works because you only constructed the object once 02:00
02:01 buharin joined
BenGoldberg Do you really believe that two different filehandles, even if they point to the same underlying file, should be considered equivilant? 02:01
geekosaur theyre not filehandles though
dataangel BenGoldberg: depends on how you are defining file handle, I am only using in this instance to get a stronger type than string, i.e. to indicate that the string actually contains a path 02:02
geekosaur that said, they should probably not be the same thing. (I think they're stat caches or something?)
dataangel I think they are just paths 02:03
geekosaur which would also mean you shouldn't persist them as they may not refer to the same file later
dataangel I think they are just paths, at least that is what the documentation makes me believe, in which case I really do think they should be considered the same thing
I mean the name of the class is IO::Path, not IO::File or IO::FileDescriptor or anything like that 02:04
02:05 cyphase left
dataangel C++ lets you define custom comparators for your sets to control what kind of identity you want, is there a way to do that? 02:05
BenGoldberg Yeah, my mistake, they are paths not file handles. 02:08
geekosaur then they'd have to implement a path cache
BenGoldberg I'm quite certain perl lets you create custom comparators. 02:09
dataangel geekosaur: or a set type that uses value equivalents instead of memory addresses, which is what I'm really looking for

lizmat timotimo: please elaborate ? 08:12
BooK nick's talk at the alpine perl workshop reminds me of a lightning talk long ago :-) 08:13
rather, one of the gimmicks in the talk 08:14
timotimo www.reddit.com/r/perl6/comments/51..._overkill/ - you see the declaration of the elements $a0 through $a8 here? 08:16
if you put the $a0 through $a8 as a subsignature for @array in the signature itself - and it doesn't seem to matter if it's (...) or [...] - it gets noticably slower
08:19 pierre_ joined
timotimo and writing it out as my $a0 = @array[0]; my $a1 = @array[1]; ... is noticably faster again 08:20
lizmat timotimo: that's because STORE needs to be pessimistic 08:21
I've looked at that before, but at runtime, there's not much that can be done
so it builds two iterators, and then assigns the result of the next iteration of the first to the next iteration of the second 08:22
that's quite a lot of overhead
timotimo OK, what can we do at compile time? or maybe in the optimizer?
lizmat the case of "my ($a0, $a1, $a2, $a3, $a4, $a5, $a6, $a7, $a8) = @array" should be compile time optimisable to $a0 = @array.AT-POS(0), $a1 = @array.AT-POS(1) etc 08:23
I think that would make that an order of magnitude faster
08:23 pierre_ left
timotimo going from [0] to .AT-POS(0) makes barely a difference 08:25

lambd0x any ideas about flat current limitations? 10:36
jnthn does rather little bakery... 10:37
lambd0x: Flat as in .flat, or as in argument passing?
10:37 xfix joined
jnthn That's limited by how many arguments the underlying VM can handle. MoarVM can handle around 2**16 though it depends on stuff like if they're named or not. JVM can only handle up to 256. 10:38
I've no plans to lift this limit in MoarVM. Note that as well as flattening the array, it also is producing a callsite object with flags for every item passed, which than has to be thrown away. 10:40
And flattened things disabled a bunch of optimizations.

lambd0x jnthn: I've impl. a quicksort and tested it with 75K int input and it gave me a flat related issue. 10:42
jnthn: e.g.,: bpaste.net/show/1849795c2214 (input); bpaste.net/show/9965889fd01f (quickSort)
nine lambd0x: so why don't you create a @results array, append to it and return the whole array? 10:44
jnthn Hmmm
jnthn tries to spot where the flattening actually happens in there
lambd0x jnthn: hahah 10:45
jnthn I wonder if something inside Rakudo is trying to do something weird with an argument list
lambd0x nine: I could try doing this. Must learn my way there though.. 10:46
10:46 Gothmog_ left, yoleaux left
lambd0x jnthn: as the input sizes increase for any alg that would augment a list of arrays let's say... it would give a " Too many arguments in flattening array." at some point 10:47
jnthn lambd0x: Yeah, that suggests something somewhere is trying to actually pass those all as function arguments. 10:48
I'm curious what... I guess an --ll-exception backtrace would show it up if the normal backtrace doesn't 10:49
It's worth an RT, anyway.

MetaZoffix is still unsure if that's the way it's supposed to be or not
But if it is, there should be an easy way to disable this behaviour IMO
timotimo i think you would be supposed to :ignoremark around things you want to match even with marks 17:38

timotimo yeah, when a thread was accepting a socket, it wasn't properly marked as "won't raise its hand when threads co-ordinate to start a GC run" 18:07
so when a thread thought a gc run ought to be started, all other threads would wait for the accept-ing thread
and until a new connection came in, the GC run wouldn't start, thus blocking all other threads from progressing

30 Aug 2016 15:42Z <[Coke]> pmichaud: for some tickets, it's easy or obvious to move them; but anyone working on anything in the toolchain or lang spec is going to deal with RT.

pmichaud yeah, it looks as though combined chars just have the properties of their base grapheme and not the combining marks. I don't know if that's correct or not. 18:25
geekosaur the problem is that at NFG level you do not have a mark, you have a synthetic of the base and the mark that is not itself considered a mark
MetaZoffix m: my @name = <John Smith>; { "$^surname, $^fir\x[308]stname" }(|@name).say
camelia rakudo-moar f0bb58: OUTPUT«Smith, John̈stname␤»
MetaZoffix lol 18:26
geekosaur and I think this is correct; I do not want ş to be considered a mark
timotimo i don't think we'd find any combined numbers + marks in unicode already declared
18:26 pyrimidine joined
geekosaur (note I chose one that at least currently has no single-char definition, the way e.g. iso8859-1 chars do) 18:27
pmichaud geekosaur: should the properties of a combined char be a combination also, though?
MetaZoffix m: say "_\x[308]" ~~ /\w+/
camelia rakudo-moar f0bb58: OUTPUT«｢_̈｣␤»
geekosaur I suspect the properties for a synthetic should be those of the base plus a prop that says that it is synthetic/composed 18:28
pmichaud that makes sense.
I agree that "7\x[308]" is no longer a Mark.
geekosaur because otherwise you break usages that expect that e.g. mark only matches actual marks, not marks composed onto other chars
pmichaud so it shouldn't have the :M property.
so that seems to me that Rakudo is correct heere. 18:29

MetaZoffix OK. What's the way to regex-match digits-only for example? Without any combinators or anything else what will mess up SoftwareXYZ I'm about to send this data to? 18:29

geekosaur it's arguably not correct in considering the synthetic to match \d though, unless :ignoremark is in effect (so, :ignoremark becomes ignore chars with the synthetic prop) 18:30

mst if you're trying to get 'only digits and no clever unicode stuff that will confuse other software' [0-9] is the usual answer
certainly it's what I do over in p5world

ShimmerFairy You might want a Uni or other non-Str string to work on codepoints, though I'm not sure if regexes are able to match non-Strs yet.
pmichaud mst/masak: That looks to me like "abuse consistent with language design" :)
mst doing it with $^a, $^b wouldn't seem abusive, using the fact that the words I wanted *happen* to be in the right order seems less right
pmichaud: yes. *that* I'll happily stipulate to :D
masak I like pmichaud's phrasing too 18:34

FASTA format is very close to this. Headers start with “>”, so I was hoping ^^ meant start-of-line
Just now checking out the stepping debugger — nice. 19:56
DrForr I'd say token TOP { <record>* } token record { <cluster-id> <sequence>+ } token cluster-id { '>' (\w+) } # and so on. 19:57
Perl6 is very lenient about whitespace; I'd toss most of the ^^ and ^ and so on, because they seem to cause more problems than they solve. 19:58
masak I'd also advise against writing any non-trivial grammar code without test-driven development
I *think* sometimes it's a good idea... but it never is
19:59 acrussell left
kyclark_ masak, I would be keen to know more of your method. 20:00
masak let me try to demonstrate it here on channel 20:01
DrForr Well, I do something similar at theperlfisher.blogspot.ro which has been somewhat neglected as of late.
masak m: use Test; grammar G { regex TOP { \d } }; ok G.parse("4"); nok G.parse("F"); done-testing 20:02
camelia rakudo-moar f0bb58: OUTPUT«ok 1 - ␤ok 2 - ␤1..2␤»
masak kyclark_: note how I write one test case with something that's supposed to match, and one with something that isn't
kyclark_: in a real situation I'd also have written excellent test descriptions (optional second argument to `ok` and `nok`) 20:03
kyclark_ Yes, nice.
masak kyclark_: I could go on, but the principle is just to keep adding positive and negative examples like that -- in small increments
you'll thank yourself as soon as the tests catch a regression for you 20:04
arnsholt Which will happen surprisingly early
masak yes, because parsing is gnarly
arnsholt And then, down the line, something you do will cause a regression you'd never have thought of
masak aye
which is even better feedback
arnsholt The spectests have been invaluable for me in that regard 20:05
Most recently when I refactored some bit of the grammar engine
masak kyclark_: also -- this probably doesn't need stating, but just in case -- it's almost always a good idea to put the grammar in a .pm file in a lib/ directory, and the tests in a .t file in a t/ directory 20:06

kyclark_ OK, here’s a start at a better infrastructure: github.com/kyclark/cdhit-parser
So far my grammar seems to be matching the header (e.g., “>foo”) and then stopping. Why would it do that? 20:19
Xliff \o/
FROGGS: Enjoy your vaca?
It's been ages since we've both been on at the same time.
mst FROGGS: ta
FROGGS Xliff: I did :o)
timotimo kyclark_: most usually sigspace eating too much and then other stuff hoping to match ,for example, start of line, but it's too late
and token won't backtrack
Xliff FROGGS: Cool deal!
mst FROGGS: admittedly, that doesn't explain anything at all to me of why my rules want to say 'make $/' 20:20
kyclark_ Got it! rule vs token
FROGGS Xliff: I've build a treehouse for my kids... so I'd say it was an awesome time :o)
DrForr kyclark_: I'd also look at dumping \n as well. Again, P6 is pretty good about finding reasonable boundaries for your rules. 20:21
20:21 setty1 left
FROGGS mst: I'm not sure what you mean... do you have some code to show? 20:23
mst FROGGS: no
FROGGS: I have no idea where to even start
that's rather the problem
docs.perl6.org/language/grammars 20:24
basically the 'make' and '.made' bit, I ... have no idea what it's even doing
kyclark_ Guys, my stuff is WORKING! Fantastic. Thanks. 20:25
arnsholt They attach an object to serve as the AST for that particular place in the tree
DrForr Also, as others have been alluding to, it's very instructional to find ways to break your file once you've managed to parse something. I'd actually start by just capturing the cluster_id and breaking that with bogus text afterwards.
kyclark_ Now to figure out this “made” stuff...
timotimo mst: you know how you can access $/<foobar> if you had a match like <foobar> in your regex?
arnsholt (.made used to be called .ast [which still works for backwards compat], a name I much prefer)
FROGGS m: grammar G { token TOP { \w+ } }; class A { method TOP($/) { make "foo" } }; say G.parse("WAT", :actions(A)).made
camelia rakudo-moar f0bb58: OUTPUT«foo␤»
timotimo mst: if you have a piece of code that runs "make 123" inside the matching part of foobar, or inside the action method foobar, then you can get 123 by calling $/<foobar>.made
that's all there is to it 20:26
kyclark_ BTW, what exactly is \N? Where can I find a list of all those escape chars?
mst timotimo: *blink*
DrForr Or, looking at it the other way 'round, make() is how you turn the text you've arsed into the tree tructure you want. 20:27
kyclark_ Wait, found it: \N matches a single character that's not a logical newline.
mst arnsholt: ooooh, right, so basically '.made' is the capture of the rule, kinda?
20:27 rindolf left
arnsholt mst: Exactly. It's whatever object you want to represent (ie, in practice serve as the AST) that particular node in the parse tree 20:27
Action methods are called when a rule is done matching, and rules are matched top-down, which means that action methods are called *bottom-up* 20:28
mst right. I think either the grammar doc needs to explain this concept space
or there needs to be a separate 'writing an actions class' doc
because ... I think I sort of get it now
arnsholt So the AST of a rule can be built from AST of the subrules
20:28 mcmillhj left
arnsholt A slightly larger example (in prose, because tuits): 20:28
FROGGS m: grammar G { token TOP { <char>+ }; token char { \w } }; class A { method TOP($/) { make $<char>».made.join('') }; method char($/) { make uc $/ } }; say G.parse("wat", :actions(A)).made
camelia rakudo-moar f0bb58: OUTPUT«WAT␤» 20:29
arnsholt Let's say you want to parse infix notation math expressions
FROGGS m: grammar G { token TOP { <char> }; token char { \w } }; class A { method TOP($/) { make $<char>.made }; method char($/) { make uc $/ } }; say G.parse("a", :actions(A)).made
camelia rakudo-moar f0bb58: OUTPUT«A␤»
arnsholt So you'll have a number rule, which matches \d+ and whose action method just does "make +$/" (ie, numify whatever was matched)
20:30 cdg left
arnsholt And a number of op rules, a la "rule add { <lhs=.number> '+' <rhs=.number> }" 20:30
mst the two interleaved explanations between them I think just gave me a lightbulb moment
SmokeMachine____ is anyone using ctags with perl6 and vim tagbar?
arnsholt And "method add($/) { make Operation.new(~$/, $<lhs>.made, $<rhs>.made) }" 20:31
DrForr If you have a rule like 'rule eq { <lhs> '=' <rhs> }' # then method eq($/) { make { op => "assign", lhs => $/<lhs>, rhs => $/<rhs> } } # returns three-address coe for the assignment o.
arnsholt Where operation has the fields operator, lhs and rhs
20:31 iH2O joined
arnsholt (Not included in this example: operator precedence; because irrelevant to ASTs per se) 20:31
mst: But you're entirely correct; this needs to be properly documented 20:32
Sadly, working on a compiler means this particular concept gets ramrodded into your brain pretty early on, which tends to make you forget it's not at all obvious =)

DrForr I have blog post on this subject at theperlfisher.blogspot.ro, but it does need to be expanded into proper documentation. 20:33

20:34 iH2O left
mst sorry. I'm too lost to really know exactly how/why I'm lost 20:34
although ... I think I might get it now
I'll have to experiment
mst is working through docs.perl6.org/language.html in order jamming it into his head
(this is my favourite way to consume docs once I decide I'm serious about something, I'll end up re-reading things later)
hm 20:35
where do I find the reference docs for 'run; ?
FROGGS class Proc? 20:36
20:36 imcsk8 left
mst ah, 'run' as a sub call is Proc.run(...) ? 20:36
FROGGS aye 20:37
DrForr Oh. That relies on some things the match object does silently for you, it's collapsing (essentially) $0,$1... ito a list and then running [+] to reduce the list. It helps if you've got a better idea of what $/ has in it befor getting that deep in.
And god *damn* is lag bad tonight.
mst right, ok, so maybe the grammars thing should have a 'you really should read this first' note 20:38

rgrinberg moritz: yeah
arnsholt Perl 6 has & both in grammars and as a junction operator =) 20:48
rgrinberg arnsholt: but not in regular expressions though? 20:49
arnsholt Grammars being the extended regular expression syntax =) 20:50
So you can do /<foo> & <bar>/
I've never had need to do it, but it's there
I think there's even a sequential && version, to mirror | vs. ||

avar I realize this is ancient, but design.perl6.org/S19.html says -a (autosplit) is one of the p5 things that didn't change, rakudo doesn't have it, is there an equivalent feature? 22:09
AlexDaniel avar: hmm, what about splitting it yourself? 22:13
avar sure, just wondering if there was a shortcut 22:14
perl6 -ne 'our %LINE; my @F = $_.split(/\s+/); %LINE{@F[0]}{@F[1]}{@F[2]}++; END { say %LINE.perl }'
perl -ane'$_{$F[0]}{$F[1]}{$F[2]}++; END{ print Dumper(\%_) }'
much shorter in v5
AlexDaniel fwiw, you can probably ｢dd %LINE｣ instead of ｢say %LINE.perl｣ 22:16
you can also omit { } like ｢END dd %LINE｣
instead of ｢$_.split(/\s+/)｣ you can write just ｢.split(/\s+/)｣ 22:17
22:17 zakharyas left
avuserow you can also use `.words` instead of splitting on space. 22:18
tailgate is there a way to set a debug flag on the commandline, and define functions diffrently if it's set? 22:19
like, if you added --debug as an option and had a Debug sub that's empty in normal use but does stuff if the flag is invoked 22:20
avuserow you can also use `no strict` to get rid of those pesky declarations, not that I'd recommend it
timotimo "no strict" will give you an incredible performance hit on your variable accesses currently 22:22
avuserow oh well. not like it saves much there anyway
