timotimo jnthn: am i reading this correctly? bounded serialisation is almost complete?
jnthn That awkward moment when you complete your weekend project on Friday night...
timotimo ah, deserialisation is still missing, ok
jnthn++
jnthn timotimo: It's missing a few important pieces.
timotimo try not to burn yourself out :)
jnthn timotimo: But it's much more there than not.
diakopter That awkward moment when weekend projects take all of weekends and weekdays 00:02
jnthn :)

Ulti yay my windows calls ran.... but didnt do anything 00:02
jnthn Yeah, though I've gotta teach some classes in the next couple of weeks. So my weekdays are gonna be a little more consumed. :)

djanatyn hello! :) 00:58
if I wanted to make a quick change to the perl6 site, what would be the most convenient way to do that? fork and send a pull request?
diakopter ask for a commit bit 01:00
timotimo i seem to have a commit bit, if noone else is around
diakopter hm, I don't know whether anyone's around who can do that
timotimo i'll be here about 30 minutes, then decommute and go to sleep
diakopter I don't have admin rights on the perl6 org
01:02 PacoAir left
timotimo djanatyn: i think pull request is easiest 01:02
huf that site still falls apart on my browser :) a <table> would work though... 01:03
diakopter huf: does more than 0.1% of people use your browser? 01:04
huf of course not
diakopter oh :P
(how was I to know..)
huf it only happens if you set the minimum font size rather large in firefox 01:05
i dont think many people do that

timotimo i wonder where to put tests for this error. 02:26
hm. typed exceptions are supposed to be standardised, no? so it would actually get into t/spec, isn't that right?
it seems a bit much to expect suggestions from all implementations, though, doesn't it? 02:27

timotimo being able to use my inside a statement is SO GOOD 02:42
i think perl6 should optimistically skip ahead blocks and parallely parse future blocks with multithreading, so that in case of correct parsing, it goes faster and if not, redundant work is just thrown away 02:46
sorear checking whether the correct parse was chosen seems nontrivial 02:47
timotimo i'd only propose it for very simple cases
like when you start doing a class {, try to find the next class { in the same level (not nested classes, for instance) 02:48
CORE.setting is full of this kind of stuff. if it could be sped up to 1 / Ncores minus overhead, that would be so amazingly cool
even use a heuristic like "where's the next class with the same amount of whitespace in front?" 02:49
hm, this seems to gotcha me: 02:50
nqp: sub yoink() { 10 }; say(my $yoinkresult := yoink()) unless $yoinkresult > 20;

timotimo so the if clause is evaluated before the left part of it 02:59
is there a nice way to do it differently?
i should switch the computation on the right side then. 03:00

timotimo i'm regularly a python guy and perl6 gives me what python lacks, so ... ;)
masak timotimo: I've had people look at Perl 6 seriously and recoil in horror.
people are different.
arnsholt masak: One possible angle could be Perl 6 and how it varies between people, or somesuch 12:06
masak yeah, that's some of the joys of reviewing the solutions.
people are all over the map.
some are an aerodynamic fit to the shape of the language itself. some write 80's procedural code. some write OO code. some write FP code. 12:07
yes, there's definitely a talk in there.
arnsholt And that's one of your stated goals with it as well, no? Getting many people to do the same things to explore the state-space for style?
masak yeah.
timotimo so, rakudo has a bit of ANSI coloring available. i'm thinking of writing that backtracking support for the levenshtein, so we get difference highlighting for the suggestions. 12:09
jnthn timotimo: Make sure the appropriate environment variable for if we should do color or not is set if you do it. I'm not sure it'll be a help or a distraction, though... 12:10
masak did we get a turn-off-ANSI option? if so, might be good to plug this into the same option.
right.
tadzik FROGGS: I don't mind taking a trip to germany :)
timotimo i was thinking of non-obstrusive highlighting. underlining the parts that were added or changed and before and after removed characters would be fine, i think 12:11
jnthn timotimo: tbh, I'd leave the coloring thing there. But doing it for variable names would be good. Even better is if you can get the "wrong sigil" thing to have a good error...
std: my @x; say $x[0]
12:11 MayDaniel joined

arnsholt starts reading up on JNI 12:22
timotimo oooh, nativecall for jakudo? :)
arnsholt I've started thinking about it, at least 12:23
But there's a fair chunk of thinking to go, methinks
timotimo one day it'll have to happen ;)
bbiab 12:24
nwc10 wonders when the IRC logger will migrate to Perl 6 12:37
(naughty me, suggesting things rather than hacking on them)
arnsholt That'll be a while I think, since it depends on search functionality and such, which is definitely non-trivial 12:38
nwc10 moritz.faui2k3.org/en/ilbot suggest that it's in (at least) two parts - an IRC logging bot, and a web frontent 12:39
anyway, if someone else wants to fix regcomp.c in Perl 5, I'd have time to hack on it. :-)
12:39 Chillance joined
arnsholt The modified UTF-8 encoding used in JNI is kind of clever, really 12:47
Oh, except that it encodes surrogate pairs from UTF-16. That's a bit icky 12:48
nwc10 what does it do? Surrogate pairs into UTF-8, and NUL bytes as non-shortest form?
arnsholt But encoding NULL bytes as 1100 0000 1000 0000 Is neat
Yeah, that's all. It's not a bad way to avoid the horrors of embedded NULLs, really 12:49
jnthn They use the same thing in the Java bytecode itself, iirc.
nwc10 careful. NUL
timotimo Non Unicode Letter?
nwc10 but surrogate pairs as 6 bytes of UTF-8 is (to my mind) sick and wrong
given that UTF-16 starts out with all the "benefits" of UTF-8 *combined* with the "benefits" of UTF-32
and then IIRC adds a "benefit" that neither have 12:50
so, if you do UTF-16 encoded as UTF-8, you've just made UTF-8 worse
arnsholt Yeah, >16-bit characters all of a sudden require 6 bytes
nwc10 you now have an O(n squared) encoding, not just O(n)
jnthn The horrible thing is that the String type is really an array of 16-bit things.
I dunno if this is true of Java, but in .Net languages you can do a .substr and it works on the array indexes. 12:51
12:51 FROGGS[mobile] left
jnthn Meaning that you can cut a surrogate pair in half. 12:51
arnsholt GAH!
That's just horrible
nwc10 I'm pretty sure that Dan and Jarkko had it right - do it all as fixed width, 7, 8, 16 or 32
which is, as I understand it, what Python 3.3 now does
arnsholt Dan and Jarkko?
nwc10 Sugalski
jnthn Trouble is, most developers never see how broken this is because 16 bits gets you all of the BMP.
nwc10 Jarkko seems to be out if "it" for long enough to no longer be the top hit 12:52
en.wikipedia.org/wiki/Jarkko_Hietaniemi
(claims not to be noteworthy)
arnsholt jnthn: Similar to the UCS-2 curse
nwc10 jnthn: it's ASCII->UTF-8, all over again?
it's like people don't learn 12:53
"whoever doesn't learn from history is doomed to re-implement it" (acme told me that - not sure if he originated that parody)
OK, Python probably isn't doing 7
timotimo "yeah, having 16 bit per character is bad enough! besides, 16 bits gives us all of the BMP. what else do we need?"
nwc10 but 7 is crafty. Assuming you're using 2 bits to encode 8/16/32 you have one state left 12:54
and 7 lets you say "pure ASCII", which is of course a subset of both UTF-8 and many legacy 8 bit encodings.
"pile of poo". Obviously. As it describes many things rather too well.
jnthn When I teach advanced C# I demonstrate this wonderful bustage. I don't think I've had a single person come to the class who knew about this problem already. :/ 12:55
12:56 not_gerd joined
not_gerd hello, #perl6 12:56
jnthn Then there was the company whose developers excitedly told me about a coding contest where they were seeing who could write the fastest string reverse in C#. None of the fast solutions handled surrogate pairs, of course...
Let alone combining chars! 12:57
o/ not_gerd
timotimo jnthn: but they were FAST!
you're missing the important part, obviously!!
does your algorithm even lift, bro?
nwc10 Advice from Klortho #11912: Evidently it's important to you to get the wrong answer as quickly as possible.
jnthn ;)
not_gerd thinks UTF-16 should die 12:58
it's prevalence is just due to hysterical raisins
keep in mind that UTF-32 is no silver bullet, though: you can still cut grapheme clusters in half 12:59
ie even UTF-32 has to be treated as a variable-length coding
jnthn Yeah. Just a very bulky one. :)

not_gerd is it possible to conditionally 'use' a module, depending on, say, an environment variable? 13:05

tadzik require? 13:06

jnthn The problem is that use Grammar::Tracer influences the contents of %*HOW 13:09
Menaing that if changes the meta-object used when compiling grammars.
It'd be easier to always use it and have it look at an env var to decide whether to dump output or not 13:10
(Which would mean adding to Grammar::Tracer, but it's probably an easy feature to add) 13:11

it's like a really angry collection of advice to get you to try harder as a programmer.
#11941 Of course it doesn't work! That's because you don't know what you are doing! 13:12
#11946 Perhaps you have forgotten that this is an engineering discipline, not some sort of black magic. 13:13
#11947 You know, this sort of thing is amenable to experimental observation.

arnsholt Yeah, it's a good list 13:14
masak the thing I *do* take away from the "How to ask questions to good way" text is that what you, the questioner, owe the people you're asking is to try to learn about and solve the problem with your current best understanding.

I think stacktraces in errors are great, but I think we're overusing them and I'm a bit sad there's no way to turn them off.
I know it doesn't count as evidence that we need stacktrace-less errors if I cite the base-tests of a competition that I set up... but we need stacktrace-less errors. :) 14:51

felher Whats the problem with error with backtraces? 15:30
*stacktraces
15:31 wk joined
masak stacktraces can be informative. but sometimes you (the programmer) know they won't be, and then there's no way to switch them off. 15:34
15:44 xinming left
TimToady stacktraces should be put in a file or log or webpage somewhere, where you can see them if you want them, but don't have to see them if you don't 15:44
along with any other pertinent cockpit recorders
easy enough if you own the current directory, a bit harder if not 15:45
masak next year's p6cc, I think I will do the base-test files in Perl 6, not Perl 5.
TimToady: I'm more concerned about the programmer having total control over what goes on STDERR than where the stacktrace ends up. 15:46
TimToady: that is, if the implementation automatically outputs "See <cockpit recorder file> for stacktrace", I'll still be unhappy.
15:47 xinming joined
TimToady sure 15:47
15:47 SunilJoshi left
flussence An option to send then to an arbitrary file descriptor would be useful (and the same for --profile output...) 15:49

timotimo so, in order to make undeclared variable names do a suggestion, i'm going to change Grammar::check_variable and build a method like is_lexically_visible that emits suggestions based on levenshtein distance. do i get the value for the $scope argument that wwould be there by using $var.ast and get the parent until i find the first QAST::Block instance? 15:56
15:57 SunilJoshi joined 15:58 am0c joined
timotimo huh, i don't see a way to get the parent of a QAST::Node. is that not possible? 15:58
masak I don't think so, no. 15:59
if you're in a situation where you want to, chances are you're approaching things wrong.
15:59 stevan_ joined
timotimo i wonder if it would be enough to just walk the blocks like i used to for the classes 16:00

tadzik yeah
I'm speaking from experience too
masak I almost linked to it here. it made me think that there are two layers of error messages that are interesting to get: one is during each compile. the other layer is during checkin/commit. 16:14
tadzik someone on reddit got downvoted to hell, but actually had an interesting solution: 'go run' warns, 'go build' dies
masak I haven't yet seen a programming language (or surrounding tooling) that distinguishes those two.
tadzik: ooh.
yeah, something like that.
folks, p6cc is now closed. 16:15
I've accepted/rejected all solutions I got before the deadline.
I'll make a blog post, but here's some early statistics for all y'all faithful channel readers. 16:16
tadzik yay
masak 32 people signed up this year.
8 contestants submitted solutions.
24 solutions passed base-test and will be part of the review process. 16:17

timotimo so, given an entry from one of the @!BLOCKS.symtable, how do i decide if it's a variable? i can't just check for a sigil, because there's sigil-less variables, too. can i nqp::istype($thing, QAST::Var) (or self.find_symbol["QAST", "Var"] perhaps)? 16:25

FROGGS so "$a!" should die 17:36
masak no.

FROGGS it should guess where the code ends?
masak they should just stop interpolating and treat the "!" or "->" as literal, IMO.
others may disagree, but that seems like the sane behavior to me
FROGGS ... if nothing follows <[.!]> 17:37
masak well, the rule is "interpolate from the sigil up to the last postcircumfix".
and so if "!" or "->" are last in the string, by definition they can't be part of the interpolation. 17:38
jnthn Trouble is, ."..."() is a valid postcircumfix.
masak (and the fact that they aren't shouldn't cause an error)
jnthn It's not failing to parse the outer string, it's failing the parse the quoted method call.

I did no vetting on whether or not they were real words. In fact, I wanted to use a lovely elvish lexicon I had compiled, but ENO ignoremark, so I had to go with english. 19:00
which is good, since it was supposed to be english. :) 19:01

jnthn has made himself a pst (parallel spectest) thingy that does that :) 20:13
pmurias jnthn: hi
jnthn pmurias: o/
pmurias jnthn: how is iterating over a hash/array that changes supposed to work? 20:14
jnthn pmurias: Non-explosively. 20:15
pmurias: It shouldn't be forbidden, but I don't think the exact consequences are nailed down.
timotimo already reached S12 without problems. i'm hopeful d)
pmurias while I can imagine sane semantics for iterating over a array changing size it's harder for hashes 20:16
if the array grows we keep iterating if it shrinks beyond the current point we stop 20:17
jnthn Yeah, hashes are harder
jnthn wonders that Perl 5 does
I can't recall the spec ruling on this, so it probably is the catch-all thing. 20:18
nwc10 for perl 5 you're specifically allowed to delete the entry that the iterator is currently sitting on
20:19 thou left
nwc10 other than that, I don't think that anything is "defined" 20:19
jnthn www.perlmonks.org/?node_id=43646 suggest similar
nwc10 and I can't remmeber what happens. It seems to be an "implementation detail"
jnthn *nod*
pmurias perldocs tells people not to do that
jnthn nwc10: what about for arrays, ooc?
pmurias otherwise elements may be skipped or duplicated
jnthn pmurias: OK. Then that means "implementation specific"
nwc10 I can't remember.
but it's storing an array index for iterator state. 20:20
timotimo oh, i fail one of my tests. hold on.
jnthn Hm. If you decrease the size of the array in my JVM port once you start an iteration it's gonna start throwing nulls at you... :)
20:20 thou joined
timotimo oh, yes, it's the incorrect throws_like 20:20

Well, fine, that's the semantics I've got on the JVM too :)
pmurias jnthn: for arrays in Perl 5, it's "Don't do that" 20:22

p6eval rakudo e80cfd: OUTPUT«1␤2␤3␤4␤5␤6␤7␤8␤9␤10␤»

jnthn timotimo: OK, great 20:27
20:27 thou left
timotimo hasn't seen much real-life use, so i don't know if the selection-heuristic is sane to get only good suggestions etc 20:27
FROGGS timotimo: np, I'll collect issues if I hit 'em ;o)
timotimo thanks a lot :) 20:28
dalek Heuristic branch merge: pushed 27 commits to rakudo/nom by jnthn
jnthn timotimo++
Yeah, I think the best way to get this exercised is merge it and see how folks find it. 20:29
timotimo one more thing i'll have to think about is the heuristic that looks if the routine starts with a capital letter and it gets called "type" instead of "routine", not sure if i should have a suggest_type that only looks for capital-letter-starting things? 20:30
jnthn timotimo: Is that in the mystery stuff? 20:31
nwc10 I'm a bit stuck here - what's the best terse phrase for the oposite of LTA?
timotimo yes, it is
BTA?
jnthn timotimo: iirc that is using a capital letter heuristic for type vs routine
nwc10 well, they aren't now "better than awesome" error messages
timotimo yes, that's what the comment above it said 20:32
nwc10 nearer to awesome?
timotimo CTA sounds good
nwc10 yes.
FROGGS nod
timotimo "close{,r} to awesome"
pmurias timotimo: couldn't the capital-letter-starting heuristic prove misleading 20:34
?
timotimo pmurias: it might! it's not my invention ;)
jnthn pmurias: STD has done it for a good while and it's not been found misleading so far, at least. 20:35
arnsholt timotimo++ # Awesome feature
GlitchMr This is fun!
I like it
pmurias jnthn: ok
GlitchMr I'm currently compiling Rakudo.
timotimo the current code would consider changing the capital letter to a non-capital letter as a distance of 0.5 unless i explicitly throw them out
GlitchMr I rarely do that, but that feature sounds so fun, that I compile it.
pmurias timotimo: you could just increase the distance for the initial capital ;) 20:36

timotimo wow, that's bloody excellent :)
GlitchMr That's old, but well - it wasn't supposed to be serious.
timotimo we were discussing use Profanity; earlier, which would cause nasty messages on errors. maybe it could be something like use Error::Profanity; and use Error::Clippy for an ascii-clippy? 20:43
GlitchMr I never have completed the Clippy error reporting 20:44
I wanted it to be too helpful...
Like mentioning missing semicolons and stuff.
