ren1us for (0 .. @pulled.elems - 1) { 04:36
Is there anywhere on that line that seems to be modifying an immutable int?
Because I really don't think there is
perigrin @pulled.elems - 1 ... maybe ? 04:38
ren1us that wouldn't be modifying an int, though. it'd just be doing basic arithmetic without changing the value of an existing one 04:39
at least i assume
perigrin the assume is where I got hung too 04:40
and why there was a mabye? on the end

lue ren1us: are you by chance writing to $_ in the loop? 05:03
ren1us @list[$_ + $pos] = @pulled[$_]; 05:07
^ the only line in the loop
i don't think I am
(lue)
lue ren1us: only other thing I can think of is getting rid of the unnecessary parens, so for 0..@pulled.elems-1 { 05:08
(also, if you want, you can rewrite the range as 0 ..^ @pulled.elems or even ^+@pulled ☺) 05:12
ren1us i'll give it a shot, but it takes a ridiculously long time to run through each iteration and only errored about 80 iterations in last time 05:15
34 seconds per iteration, actually, lol 05:18
i should probably try to do something about that
lue If it happens in a consistent spot, you might be able to shortcut it for testing with something like 80..^+@pulled , or even just print the element of both arrays when it errors.
ren1us i know the array element, it just shouldn't really matter 05:19
but yeah i'm printing out the indexes now so that should help fix it if it happens again 05:22
lue ren1us: One last thought: if at some point in the code you do something like @list[$someplace] := 42 , you wouldn't be able to assign to that position in the list later. 05:23
05:23 [Sno] joined
ren1us I don't even know what the := operator does so I don't think I do that 05:28

moritz thought so 07:08
anybody interested in investigating the failures?
FROGGS interested yes 07:10
but I already do too much in parallel, so it will take time 07:11
moritz has to &work :(
ChoHag if %foo contains a bunch of class attribute values, and |args from the sub's signature contains some more, some of which will overlap with %foo's entries, can I say $bar = Bar.new(%foo, \args) and have it DTRT?
Also, is it |args in the sig to catch the arguments as is, then \args in a subsequent call to expand it to the arguments originally provided? 07:12
timotimo i think it's |args to expand it later
ChoHag I have not used containers enough for it to be second nature what does what.
moritz ChoHag: use |args to flatten something into an argument list 07:28
ren1us okay this error is starting to really annoy me

moritz calling functions binds the parameters 07:33

timotimo aye, have "@list is copy" or "@list is rw" in your parameters
ren1us i pray this works 07:34
it's kinda funny, though, because that block runs properly over 100 times, and then almost randomly breaks
timotimo strange indeed. 07:35

allow pointer math using OpaquePointer type

We will now see the memory address a OpaquePointer is about when calling its .gist, it is also now round-trippable by calling .perl and EVAL. Also, it will return the memory address when being used as a number, so that we can walk the bytes of a CStr or obtain addresses of Ctsructs in a list when we know their size.		 07:53

timotimo and with one hand only, too! 08:01
masak it's so we mere mortals will have a chance to follow along. 08:03
vaskozl: out of curiosity -- what's your own level of mastery over vim?
vaskozl uhm, I don't really know, on what scale? 08:04
it's my primary editor, that's for sure! 08:05
moritz on any scale you like, really 08:06
08:06 denis_boyun_ joined 08:07 Isp-sec left
vaskozl it's feeble in comparison to #vim, but yet enough to answer the questions of ordinary warriors learning to find their way with vim 08:08
so I'm pretty confident with it using it for everything including note taking in all my classes for over an year now 08:09
masak vaskozl: let me put it like this: if I put you on Notepad, which features would you most miss from vim? 08:10
vaskozl my vimrc is of a second order of magnitude and is only getting bigger as I expand vims features to the path of enlightment

vaskozl macros would be big thing too, not to mention be able to pipe content trough programs and return it on screen 08:14

masak no, you can return from inside a given. 08:16
ChoHag Oh.
masak see above.
moritz ChoHag: I'm pretty sure Windows XP fixed the 64k limit in notepad
ChoHag Hmm interesting, now I can't return before the given. 08:17
vaskozl oh and I somewhat forgot: notepad doesn't run in a bloody console
ChoHag I'm sure I checked that last time I was in this function (days ago).
moritz ChoHag: what do you mean by "can't return"? 08:18
ChoHag vaskozl: For that, there's qbasic.
Is ms edit still based on qbasic these days?
Attempt to return outside of any Routine
moritz ChoHag: then the problem is that you've already returned.
ChoHag Maybe it was a sub {...} not a -> {...} when I tested.
moritz or that, yes
ChoHag Is there a difference?
moritz yes
ChoHag You can return and remain inside the function?
moritz return is bound to routines

moritz by the time the inner code block is run, you've already returned the block from f()
ChoHag The return isn't in f, it's in f() 08:20
moritz and the same can happen with lazy list generators
ChoHag I shall have to look in to that at some point.
More weird things to break...

grondilu I had hard time figuring out I should put ?? after <disambiguation> and not just ? 08:53
otherwise it just failed silently :/ 08:54
masak yes -- this is where tests help greatly. 08:59
I find the combination of grammars and tests to be quite helpful.
grondilu sure, but finding and writing examples for tests is a bit tiresome. 09:00
moritz but you do that anyway
otherwise you wouldn't know it works 09:01
you just do it ad-hoc
grondilu I made one manual test with a single game and truncated it for debugging. I know it's silly to do that but I guess I'm not used to make tests properly yet. 09:02
09:02 troydm joined 09:04 potatogim is now known as PotatoGim, pecastro joined
masak finding and writing examples for tests (a) focuses the implementation tremendously, and (b) provides excellent regression guards. 09:04
...in my experience. YMMV. 09:05
moritz grondilu: well, but you already work with some examples in your head when you write the rules

tadzik ayes 11:52
colomon_ huh. 11:54
why does emmentaler installing File::Find to emmentaler/installlib break everything? 11:55
tadzik hm, good question
is that installlib in perl6lib? 11:56
colomon_ don't think so.
but maybe I'm wrong?
tadzik I don't know :) 11:57
but installing panda deps has always been a pain
colomon_ it's /home/smoker/emmentaler/installlib
so no

teodozjan I need to compile moar ... it will take moment 11:59
is moar default backend on purpose if not specified --backends? 12:01
jnthn What other flags did you pass to Configure? 12:04
I'm pretty sure --gen-moar implies --backend=moar for example
teodozjan i mean if i do --gen-parrot --gen-moar moar will be defailt 12:05
jnthn I suspect if you want to override that you can --backends=... 12:06
I suspect it's just the order it checks for the flags in Configure
teodozjan i know i can :D but I'm thinking about new users that are not sure what backends are and which to use
jnthn Well, Moar is the right backend for most new users. 12:07
Tends to be fastest for one, and if nothing else because it's what most Rakudo developers primarily develop against, so we spot breakage a bit faster. 12:08
Though daily test runs mean nothing goes unnoticed too long.

Is there an RT for it, or a golfed test case?

panda, emmentaler?
12:34 ivanshma` is now known as ivanshmakov
colomon_ tadzik: looking at the code now 12:34
panda's I reckon
Panda::Installer has $.destdir 12:35
but it also has method destdir
12:35 jnap joined
colomon_ which doesn't even look at the value in $.destdir 12:35
tadzik lol
how could this happen 12:36
12:36 ivanshmakov left, ivanshmakov joined
colomon_ very carefully, I presume. ;) 12:36
tadzik oh, method destdir is just for setting $!destdir
but, yeah, $.destdir then calls that method again
colomon_ setting the default
tadzik it's a miracle this works
colomon_ right
easy peasy fix, I think -- just rename the method to something else 12:37
colomon_ would do it, except he's guessing tadzik is already doing so... 12:38
colomon_ suspects this will improve emmentaler's performance, too 12:39
tadzik no, I'm not, go ahead :)
tadzik at $work
colomon_ do I have a commitbit for panda?
tadzik I hope so
if not, that'll be an easy fix too
colomon_ do not
tadzik fixed 12:40

at the end of the emmentaler run
FROGGS (because that must feel like working with Linus Torvalds standing behind you) 12:46

FROGGS ahh, two days before delivering the blog post... clearly I was under pressure!
jnthn: it is not hidden... and given the usefulness of JSON... I mean, we don't become a PHP, do we? ó.ò 12:51
moritz I'm of two minds about JSON in core. But the day we have an XML parser in core, I quit.

moritz .perl is perl readable :-)
FROGGS sort of
tadzik I read "edible" :O
FROGGS tadzik: what ever you want, we can implement it :P
colomon_ is not sure he wants edible data structures 12:54

jnthn timotimo: A way of writing an alternation of literals 13:40
['+'|'++'|'#']
But readabler
timotimo oh
right, it's a list-of-strings, didn't realize that works like that 13:41
jnthn Key is the space after the < :)
timotimo aye
grondilu notice that there is the same notation used for pieces, files and ranks 13:43
< K Q R B N > and so on
timotimo right 13:44
i ought to remember that 13:45
13:47 jsn_ left
smls How do I make a grammer automatically die with helpful error message when it can't parse the inout string? 13:50
grondilu probably with Grammar::Debugger 13:51
timotimo that's an interesting thought; if it fails to match, mix in the debugger hooks and try matching again?
grondilu (though personally I've never managed to make it work)
jnthn smls: If you want a helpful error you actually need to produce it.
Just like the Perl 6 grammar does.
smls y can't it produce it for me? :)
jnthn How the heck does it know how to? 13:52
smls tell how far it managed to match tokens, what followed, and what it expoected to follow
jnthn The best you can do in a generic way is just say "something when wrong at this point"
colomon_ which is still quite useful...
timotimo it would be interesting if the highwater stuff could be autogenerated for user grammars
jnthn True. That's doable with a [ $ || { die "Failed to parse at " ~ $/.CURSOR.pos } ] or some variant. 13:53
That pattern works in general, though
13:54 moistcherry is now known as hoverboard
jnthn token foo { thing(s) that we should always match one of || error handling } 13:54
13:55 chenryn joined
timotimo can we have something that generates an eject symbol stringie thingie? 13:55
jnthn timotimo: We actually do track that stuff anyway...
For all grammars. But it's not spec'd in any way.
zengargoyle my attempt at Text::Fortune works well enough and has enough tests to start trying to pretty it up for ecosystem maybe.
smls P5 Parse::RecDescent does it: metacpan.org/pod/Parse::RecDescent...r-handling
jnthn Hm, that looks like it is doing the same highexpect thing... 13:56
Well, I guess we can try to spec a way to expose that 13:57
But still, notice that the || <error> went explicitly into the grammar.
TimToady the fuzzy bits are what you do after that to "recover"
"find next semicolon and assume it's a new statement" 13:58
jnthn Well, that's the sorry/panic distinction in the Perl 6 grammar, I guess...
13:58 teodozjan left
TimToady yes, we don't try to find the next statement when there's a parse error 13:58
jnthn Aye. Probably sane.
TimToady that usually just produces cascading, confusing errors
jnthn MSVC is incredibly bad at knowing when to give up.
TimToady and if the parser is fast enough, you just fix the one and re-run 13:59
13:59 gfldex left
TimToady and if you find another such, assume there's a trend and fix all of 'em 13:59
trying to find more errors is a vestige of the days of punch cards and line printers 14:00
of course, if we just have a semantic error, we just worry and keep going 14:01
jnthn Anyway, we could expose the highexpect, but half the time I find its suggestions to be better at bulking up the error report than helping me know what's wrong...normally it's the message and the position indicator that help most. 14:03
TimToady well, worry or sorry
well, I think people learn to ignore the bits of it that don't apply 14:04
jnthn But given it's tied into the LTMer, I kinda had to put that stuff in Cursor, and so we do actually track highwater and highexpect for everything we parse...
...so if we can pick an API it's no problem to expose that.
Apart from it commits us to continue collecting the info :)

moritz it's not fast either :-)
if you only need it for error messages, I guess that's fine 14:13
timotimo if you only do it once, it shouldn't be much slower than what we do
moritz in rakudo, we put line annotation in every statement or expression, which means we need that number *very* often, and caching it is crucial

timotimo seems like even though we said "multiple implementations yay" at one point, that's kinda not the way it is any more 14:16
FROGGS timotimo: which is good I think
smls I think I'll go with moritz++ suggestion :)
FROGGS I mean, it is not like there is a race between several groups of like 30 devs each 14:17
moritz FROGGS: when niecza came up, we were very happy about modules that didn't use rakudo-isms 14:19
I'd like to keep it that way, to not raise the burden for new implementations (or a niecza or pugs revival) even higher
FROGGS moritz: yes, there are several benefits of having more than one impl
I just don't see it as a priority anymore
smls moritz: So what should become of modules like NativeCall which need NQP? 14:20
jnthn I'd like to keep it that way for another reason: I don't want to get Rakudo to a point where I can't refactor nqp::foo or NQP related things without breaking userland code.
FROGGS smls: the other implementations should expose an NativeCall-like interface
jnthn smls: NativeCall arguably should be "in core"...
smls I guess
zengargoyle that was my beef with old Rosetta Code examples, comments along the lines of "this is for parrot/niecza" 14:21
14:21 SamuraiJack_ joined
FROGGS zengargoyle: but that is not because it uses compiler internal stuff, this is because the needed things are only implemented on a few compilers 14:21
that'S a difference
smls: so scratch my proposal and do not use the nqp module :o) 14:22
14:23 chenryn joined
FROGGS you might even have precomp problems when using it 14:23
14:24 sqirrel left
FROGGS even in Perl 5 there are ppl who prefer pure Perl 5 modules over XS-based, and they only have one compiler 14:25
so sticking to pure&proper Perl 6 is the way to keep things working 14:26
smls yeah +$/.prematch.comb(/$$/) works fine 14:27
zengargoyle is using /$$/ a better idea in general than "\n"? 14:28
smls it means the number will start from 1 not 0 :) 14:29
Is there still a shorthand for die'ing without a backtrace, like « die "Message\n" » in P5? 14:30
Or is it « say "Message"; exit 1 » now?
zengargoyle i've been wondering how IO .get is handled, is everything massaged into "\n" on various platforms? 14:32
moritz smls: there isn't a shortcut (yet)
jnthn Also, probably wants to be note "Message" to get it on stderr 14:35

ren1us just to make sure i'm not missing something, because i want to make sure i'm not thinking in terms of the wrong language

psch i also noticed that the &return call in line 22 of the first file isn't the only thing that breaks, &die breaks in the same spot as well

psch jnthn: the setting is outer from GLOBALish? 22:11
i.e. i was wrong and the outer chain breaks (at least) one element before it should? 22:12

psch also, tc.curFrame.oLex has a null element where i think $*DISPATCHER should be, i don't know if that's significant 22:15

carlin colomon_: it says it installed LibraryMake in /home/smoker/emmentaler/installlib/lib/ but in the error it doesn't seem to be looking for deps in that directory :s 22:18
colomon_ yes 22:19

colomon_ carlin: I wonder if the problem is in calling your Build.pm 22:26
Yeah, I'm betting that's it. 22:32

colomon_ github.com/tadzik/panda/blob/maste...der.pm#L57 22:33
carlin Auth::Pam::Simple which uses LibraryMake seems to have the same problem 22:34
colomon_ yes
carlin are installed deps not being made available during Build time
colomon_ I think they're not being made available during Build.pm time
22:36 rurban1 left
colomon_ if you look at the code at that link above, it requires Build.pm right into the executing copy of Panda. But I think (though possibly I'm wrong) it doesn't do anything to make sure the current panda can see the emmentaler install directory 22:37

jnthn psch: GLOBALish isn't a lexical scope 22:49
psch: Though UNIT is, and the UNIT scope contains GLOBALish. There should be one more scope beyond that.
psch jnthn: right, so i have confirmed your first hunch with some 6 hours of jdb debugging :) 22:50
let's see how long it takes me to find out what to do where to try and repair it! 22:51
jnthn Last time I saw an issue like this, it related to github.com/rakudo/rakudo/blob/nom/....nqp#L1686 22:54
The comment there is actually oudated, though; the JVM is also using the same codepath as Moar there these days.

jnthn oh, and the other place was github.com/rakudo/rakudo/blob/nom/...r.nqp#L298 22:56
psch thanks, i'll look around from there tomorrow and see if i can do anything about this 22:57
for today it's good night o/
jnthn OK; thanks for looking at it 22:58
