03:47	slavik	hallo
03:48		Psyche^ joined #perl6
03:48	slavik	is there a way in rakudo to recursively print everything? something like data dumper or PHP's printr(). I know about the $var.perl, but it doesn't seem exhaustive
03:49	slavik	I am mainly interested in printing the structure of a match object, because some things happen which cause something to be nested a level deeper and I would like to understand why
04:02		elmex_ joined #perl6

04:26	slavik	given two arrays, what is the correct way to zip them into a hash? %hash = @keys Z @values; ???

05:14	slavik	%hash = $/<blah>[0] | $/<blah>[1]; doesn't work :(
05:14	slavik	s1n: I am pretty sure it's supposed to be like in perl5
05:15	slavik	if the left is smaller, then the return is -1, if the right is smaller the 1, if equal then 0

12:41	masak	Mark Lentczner wants me to tell everyone that he'll be updating his table of operators http://www.ozonehouse.com/mark​/blog/code/PeriodicTable.html -- perhaps in time for the new year!
12:42	lambdabot	Title: Mark Lentczner's Journal
12:49	moritz_	(Mark Lentczner)++
13:01	masak	what should happen with an $obj.meth() call when $obj contains an undefined value?
13:01	masak	oops, I meant 'an $obj.?meth() call'
13:02	moritz_	masak: definedness is just a property of an object that is rather arbitrary
13:02	masak	I'd hope that the question mark would make Perl 6 not warn about the 'use of uninitialized value', but maybe that's misusing the .?meth() notation.
13:03	masak	rakudo: my $a; $a.?meth()
13:03	p6eval	rakudo 33042: RESULT[undef]
13:03	masak	hm.
13:03	masak	rakudo: my $a; say $a.?meth()
13:03	p6eval	rakudo 33042: OUTPUT[Undefined value returned by invocation of undefined method␤␤]
13:03	masak	oh, but of course it warns there, sorry. :)
13:05	masak	rakudo: my $a; for 1..2 { say ~$a.?lc; $a = "OH HAI" }
13:05	p6eval	rakudo 33042: OUTPUT[␤oh hai␤]
13:05	masak	it actually seems to DWIW
13:05	masak	I have no further questions, your honour.

14:27	masak	rakudo: my $a = undef; say $a.?lc.WHAT
14:27	p6eval	rakudo 33043: OUTPUT[Use of uninitialized value␤Str␤]
14:28	masak	in both cases, $a contains a Failure, right?
14:28	moritz_	no
14:28	moritz_	'my $a' will initialize with an Object proto
14:28	masak	rakudo: my $a; say $a.WHAT; $a = undef; say $a.WHAT
14:28	p6eval	rakudo 33043: OUTPUT[Failure␤Failure␤]
14:29	masak	looks like Failure to me.
14:29	moritz_	urm

19:08	jnthn	Correcting the corrections to the corrections... ;-)
19:09	moritz_	indeed :)
19:09	jnthn	The multi method case for is default isn't so surprising, given multi methods don't really work at all yet.
19:09	jnthn	It'll be some oddity with the invocant.
19:10	jnthn	It's high on my "to fix" list.
19:10	moritz_	oki
19:10	moritz_	I'm writing tests for 'is also' on classes right now
19:10	jnthn	cool
19:10	* jnthn	thought he'd maybe done some for that, but maybe not
19:10	moritz_	so far I haven't found a single bug when extending user defined kclasses
19:11	moritz_	Str seems to be problematic
19:13	moritz_	Int is fine
19:13	jnthn	Ah, Str...
19:14	jnthn	Str is...special.
19:14	* moritz_	sees memories of old pains emerging...
19:14	jnthn	You shoulda seen what it took to make $something_that_is_a_string does Foo kinda stuff work.
19:15	jnthn	It boils down to Str just mapping a PMC, where as most other things really are high level classes.

19:29	jnthn	moritz_: Great. I'm cooking nom at the moment - could you file a ticket about the Str one?
19:29	moritz_	(I can even add methods to List, and use it in Array, because of the inheritance)
19:29	moritz_	jnthn: I'm updating (and renaming) #56602 as we speak

20:09	moritz_	masak++ for noticing ;)
20:25	s1n	may be off topic, but does anyone know of any good perldoc syntax highlighters?
20:26	s1n	err well, pod that is
20:26	masak	s1n: I like the one they use at perldoc.perl.org :)
20:26	moritz_	s1n: vim does a not-too-bad job, but it's not exactly good either
20:26		tewk_ joined #perl6
20:27	s1n	moritz_: got a link? i use vim and it's like all one color and i'd like to have the keywords highlighted
20:28	moritz_	s1n: there's some option you can use... forgot which. But if you open a .pod file it should display a bit better
20:29	s1n	moritz_: is it good practice to move all pod to seperate .pod files?
20:29	moritz_	s1n: no ;)
20:30	masak	s1n: :syntax on
20:30	moritz_	:let perl_include_pod I think
20:30	s1n	moritz_: unknown variable
20:31	s1n	masak: just colors everything default terminal color (":set syntax=on" that is)
20:31	masak	s1n: ok, too bad.
20:31	moritz_	s1n: :let perl_include_pod=1 and then :e again
20:32		slavik joined #perl6
20:33	s1n	moritz_: yeah, i just read that on vim's docs, but it didn't say anything about the :e, what does that do?

20:34	moritz_	s1n: it reads the file again
20:34	s1n	oh, heh, short for edit
20:38	s1n	sweet, thanks guys, finally proper coloring of my perl code :)
20:38	moritz_	no problem
20:38	slavik	I use perl coloring :P
20:39	s1n	not sure why some of those aren't set by default for perl

21:11	masak	I want to add a test that checks that a block containing first $foo and then $^foo dies in some way. do I use dies_ok for this?

21:54	masak	welcome to #perl6. :)
21:55	guiwiz_	thank you
21:55	guiwiz_	do you know if there is a mirror for run.pugscode.org?
21:55	masak	guiwiz_: not to my knowledge, no.
21:56	guiwiz_	too bad... i wanted to try perl6 but pugs won't install on my computer
21:56	masak	guiwiz_: have you tried Rakudo?
21:56	masak	it's worth a look.
21:57	guiwiz_	i need an interactive-mode interpreter, does rakudo acts like this?
21:57	guiwiz_	act*
21:57	masak	guiwiz_: yes, but not very well in my opinion.
21:57	masak	it's better as a compiler.
21:57	guiwiz_	ok
21:58	masak	guiwiz_: the reason I say so is this bug: http://rt.perl.org/rt3/Tic​ket/Display.html?id=58258
21:58	lambdabot	Title: #58258: The Rakudo REPL has no long-term memory
21:58	masak	it kinda destroys all plans for interactive work.
21:58	guiwiz_	i will try then
21:58	guiwiz_	i just have to install parrot?
21:58	masak	guiwiz_: yes.
21:58	masak	and then `make perl6` in languages/perl6

22:40	p6eval	rakudo 33107: OUTPUT[3]
22:41	moritz_	guiwiz_: try it with 'say' instead of 'print', maybe your terminal doesn't like it when there's no newline at the end of the output
22:41	guiwiz_	thank you, that works
22:41	jnthn	If that is the answer, we likely want to flush...
22:41	jnthn	That looks like a bug in the REPL.
22:42	moritz_	aye, fflushing wouldn't be bad
22:42	guiwiz_	i did something wrong?
22:42	moritz_	but my terminal also swallows short output from other jprogrms that have no line ending
22:42	moritz_	guiwiz_: no
22:43	moritz_	maybe we did something wrong, though ;)
