so i put all of the output

Radvendii oh, and hey sorear! long time no see! 04:38
how are you?
sorear "long time"
I've only been incommunicado for ~20 hours
Radvendii: you appear to be trying to build rakudo with an incompatible parrot 04:39
Radvendii yeah but i haven't been on #perl6 in a *while*
but i used --gen-parrot 04:40
shouldn't that update it?
for configuring i ran: "perl ./Configure.pl --gen-parrot --prefix=/usr/local/"
sorear you're updating, but you're not using the update because of --prefix 04:50
you need to use --gen-parrot-prefix instead.
Radvendii ah
will that also set --prefix?
or should i set both
to the same value 04:51
sorear that will also set --prefix, yes 04:52
Radvendii --gen-parrot-prefix isn't an option though, don't i have to set --parrot-option='--prefix=$path' 04:54
i think it's working now 05:03
thanks
if use .shift in the body of a program, will it take the first command line argument (from @ARGS) 05:06
sorear no 05:08
Radvendii ,':-/
so i should do $_=@ARGV first?
or given @ARGV{}
japhb Am I correct in assuming that S32-setting-library/Exception.pod:130-131 needs to be revised after github.com/perl6/specs/commit/d28c...d2ae8fe92e ? 05:09
Radvendii i am correct that that was the behavior in perl5 though no? i'm not imagining things.
sorear Radvendii: I have no words for this. 05:11
Radvendii as in, you don't know?
japhb Radvendii, shift with no arguments in Perl 5 was sensitive to context: It shifted @_ inside a sub, or @ARGV outside a sub.
Well, to a first approximation ... see `perldoc -f shift`
Radvendii japhb: that's what i though. i see that was taken away in perl6
sorear This feature is incredibly stupid and I have *no* sympathy for anyone who misses it. 05:12
japhb Radvendii, special cases and magic lists of exceptions were much reduced in Perl 6.
s/were/are/ I suppose
Radvendii understood. 05:13
I would think though, that @ARGV really serves the purpose that @_ does, except outside of a subroutine
japhb While I love using Perl 5's auto-shift of @_ in subs, that's only because I don't have real parameter lists and methods.
sorear $_=@ARGV reminds me of a story about an ALGOL programmer who switched to C and then started starting all eir programs with #define BEGIN { #define END } 05:14
japhb Radvendii, yes, that mnemonic of sorts was perfectly useful in Perl 5. Perl 6 doesn't really need that any more.
Radvendii right, but from quick programs, i dont really want to deal with it
why not?
sorear: what? what would that even do? 05:15
japhb I just had a discussion at $day-job last week about ancient code we'd found in which someone managed to write 50's/60's era assembly language in Perl 5, metaphorically speaking. 05:16
Radvendii as in, totally obfuscated
?
japhb Radvendii, because subs have real parameter lists that do intelligent parameter binding, and in particular, MAIN has a very magical parameter list that can do command line parsing. 05:17
Radvendii, no subroutines. All control flow done by setting globals and jumping.
Radvendii japhb: oh i see
but I liked perl5's conspicous lack of a MAIN subroutine… ah well 05:18
japhb It was quite effectively obfuscated even though it clearly wasn't intended to be, since the mental disconnect in most readers was pretty extreme.
The author was convinced that these new-fangled subroutines were just confusing. (I kid you not.) 05:19
Radvendii I can actually see that… if your brain is hard-wired one way…
japhb Radvendii, sorear's ALGOL-to-C joke was basically talking about using the C preprocessor to redefine curly braces to be the "more readable" BEGIN and END. 05:20
Or rather ...
Radvendii oooh
i see
japhb to allow the programmer to use BEGIN and END instead of curly braces.
Radvendii the message of the story being, adapt to the language, don't try to make it fit to your limited worldview 05:22

Fix naming skew (which also fixes a semantic mismatch)
 05:24
japhb Radvendii, exactly.
Radvendii and this lies in balance with TMTOWTDI
japhb Radvendii, I'll answer that with another story: 05:25
When I was in high school, I used to make up words to fit in English class. The professor told me to learn the right words to use, and use those instead of ones I made up. 05:26
05:27 tokuhirom left
japhb I protested that Shakespeare, who we were constantly being told was the greatest English poet, had possibly introduced more words into the English language *himself* than any other famous author. 05:27
So why couldn't I?
05:27 rsimoes left
japhb The professor said: You have to learn all the rules, before you can be clever breaking them. 05:27

Radvendii alright… fair enough. 05:28
japhb It's worth noting that I've heard a similar sentiment in a wide range of fields from masters of each. It's rather humbling, actually. 05:31
05:31 rsimoes joined
Radvendii mhmm. However… i would say that sometimes someone who has not been indoctrinated into the way of thinking of a field can offer some valuable *different* insite… 05:32
for example, i feel like the interpretation of the torah has become such that there is only one way of interpretation, because everyone studies from, and learns from, the torah scholars of the past, and so they do not think to think a different way. 05:34
japhb Sure ... but one has to be careful to differentiate true insight from the all-too-seductive "make your scary moon world look like my friendly Earth"
Radvendii mhmm…
japhb Radvendii, how then do you explain the vast range of actual life choices made by those who nominally follow the teachings of the Torah? 05:35
And then there's "Your dogma just ran over my karma."
It takes a great deal of experience to know when the masters are wrong -- as they inevitably eventually are. 05:37
Radvendii japhb: This is a great conversation, and i would really like to continue it, but it's 12:30 my time, and my brain is fried. 05:39
I think I'm going to go to bed
thanks for the stories, and discussion
japhb And all that said (and to come full circle) ... you will rarely find a community more welcoming of other language's viewpoints than this one. :-)
You're quite welcome, and thank you.
Have a good night!
Radvendii oh, for sure
good night 05:40
o/
05:40 Radvendii left
sorear japhb: are you sure that this community is actually inclusive and pluralistic? maybe it's just groupthink telling you that. :D 05:40
japhb That was very much *not* the conversation I expected to have after popping my head in here for the first time in months. 05:41
Nah, I've seen it in action.
Plus, a group of people having a willful hallucination can make it true (or effectively so).
And how have you been, my fine fellow? 05:42
sorear today could definitely be better. 05:44
japhb Oh? What troubles you? 05:45
sorear last night there was a (pre-announced) power cut, so I shut my computer down
this morning it told me it had no hard drive
japhb OUCH
Been there, hated that.
sorear for no apparent reason I then cycled the power about 15 times
on the ~15th try it booted and is working fine 05:46
which makes me think the BIOS is fried, if that's possible
japhb Yeah, that'll make you feel *oh* so comfortable.
sorear no I/O errors on sda in dmesg yet
(I'm on it right now, not cellphone IRC or anything like that) 05:47
japhb The last time a similar thing happened to me, it turned out to be residual charge on the case. After a few failed tries to boot, I went to open the case, got a shock strong enough to sting for a few seconds, and it booted just fine after that.
Apparently the maintenance on the power system had led to the ground line getting charged, or some such. 05:48
sorear in the middle (not the end) of that sequence of attempts, I opened the case and reinstalled all the IDE cables
geekosaur grins and giggles, open it and reseat all the cables. but, my alternate guess is not fried bios, it's a borderline component that only works properly when wrmed up to operating temperature
ah, ok
japhb thinks for a bit ... what do you have between your computer and mains? 05:49
sorear procured a portable drive and attempted a backup...
TimToady charging UPS drawing down voltage, you're thinking?
sorear [ 5607.913634] Buffer I/O error on device sdb1, logical block 786687 05:50
TimToady the fact that sorear could say the power was out seems to indicate a UPS
japhb is wondering if sorear's power supply is limping and providing cruddy power (bad regulation or noisy output)
sorear that's what I was going to back up *onto*
japhb ouch again
TimToady low voltage while the refrigerator cools down? 05:51
sorear TimToady: no, I could say the power was out because I had a piece of mail from SDG&E saying "we'll disconnect your power at 10pm for maintaince, please make sure you have no generators running that could electocute our employees"
TimToady ah
japhb TimToady, yeah, possibly, or just component temperature changes moving it in and out of spec. A marginal power supply plays havoc on the system (and runs it into the ground quickly, I might add -- some components REALLY don't like crappy power). 05:52
TimToady well, I guess I'm not Sherlock Holmes :)
japhb idly wonders just how many actors have played Holmes over the years .... 05:53
TimToady it's that dirty power a-comin' from that thar nukular station
japhb Heh.
sorear, did you ever answer what you had between your computer's power supply and the wall? If so, I missed it. 05:54
sorear I'm not sure.
Or rather
One power strip w/breaker (and possibly a MOV?) and one brick that claims to be a UPS
japhb How long has it been since you had the electronics in the UPS replaced? 05:55
TimToady as I say, a charging UPS can draw down the voltage some
depending on how good the circuitry is
japhb Nodnod
Also, what brand/model of UPS is it?
TimToady has yet to find a good brand... 05:56
sorear I don't think this "UPS" charges.
05:56 birdwindupbird left
japhb I've been happy with running an APC Smart-UPS at about 20-40% load for quite a long time. It's had it's guts swapped out two or three times over the years, and I upgraded it from 1000 VA to 1500 VA at one point. Otherwise it's taken quite a few hits from crappy mains over the years, without the computers being (apparently) the worse for wear. 05:57
TimToady I can't count how many UPSs I've killed, and we have pretty good power here most of the time... 05:58
sorear For the entire time I've had it, it's just been a very heavy extension cord - which had a purpose at one point, but I just noticed it no longer
TimToady maybe UPSs thrive on adversity, I dunno...
sorear (prevented me from unplugging my computer when tripping - since last move, cord no longer crosses a footpath) 05:59
japhb The last time I had to have the guts replaced (and paid the non-trivial fee), I asked why UPS systems die way earlier than the computers they protect. The support guy basically said "because the UPS keeps sacrificing itself". 06:00

sorear amazing. complete lack of overnight discussion. 16:57
good * #perl6
[Coke] ~~ 17:00
benabik When nobody talks on #perl6, I tend to assume I was on the wrong end of a net split.
sorear I don't see a netsplit. 17:02
benabik It's not always true, but it's more common than nobody talking.

Radvendii is that on purpose?
that you can't assign with whatevercode?

17:06 jferrero left
benabik Looks like that's not even becoming a whatevercode. 17:07
It's just assigning to a Whatever, I think.
Radvendii hahaha
really?
nom: my $a="foo"; {$^a="bar"}($a); say $a;
p6eval rakudo 42695e: OUTPUT«Cannot assign to a readonly variable or a value␤ in block <anon> at /tmp/qVV8Leisl4:1␤␤»
benabik But I wouldn't expect (* = 'bar') to work... Parameters are readonly by default. 17:08
Radvendii awwww… what's with everything being readonly?
benabik nom: my $a = 'foo'; (-> ($b is rw) { $b = 'bar' })($a); say $a

nom: my $a = 'foo'; (sub ($b is rw) { $b = 'bar' })($a); say $a
p6eval rakudo 42695e: OUTPUT«bar␤»
Radvendii what's the justification for making everything readonly by default (im actually curious) 17:10
17:11 GlitchMr left
Radvendii O.o maybe there should be a "use readwrite" option to let everything be readwrite by default 17:12
benabik I think that would kill a lot of optimization.
You'd have to create a container for every constant passed in.
Radvendii oh…
17:12 jferrero joined
Radvendii what about just for non-constants 17:12
just for if you are passing a variable 17:13
here, this is the xy problem again 17:14
you know how one can say $a == 1|2?
basically, i want to say $a (==2 | > 5)
or, more specifically $a (==2 | = 5) 17:15
(a.k.a. if it doesn't equal 2, make it 5
i could just do "$a == 2 || $a = 5" 17:16
but if $a is a more complicated expression…
benabik A complex expression that returns a lvalue? 17:17
17:17 jferrero left
Radvendii yes 17:17
benabik I'd probably do something like `my $a := complex-expression(); $a == 2 or $a = 5
Radvendii yeah… maybe i should let up on the code golfing :P 17:18

typo: printf => sprintf
 17:56
benabik But there is a printf... 17:57
nom: printf "foo %s baz", 'bar'
p6eval rakudo 42695e: OUTPUT«foo bar baz»
sisar what ?
oh noez 17:58
sprintf and .fmt are (almost) the same, right ?
benabik That I don't know. 17:59
sisar benabik: any idea where is printf specced ? its not in S32. 18:01
colomon sisar: 18:02
method fmt(Str $format = '%s') {
sprintf($format, self);
}
flussence S32/IO:472, S32/Str:403 18:03
colomon that's in niecza's Cool class.
flussence printf isn't really specced, but sprintf is
colomon sisar: it's not exact, some classes have more specialized versions of .fmt 18:04
18:04 GlitchMr joined
sisar colomon: i know. that is why i said almost above ^. 18:04
TimToady composite types tend to iterate the format as needed 18:05
perl6: say %*ENV.fmt("%s -> %s") 18:06

sisar if there is nothing no printf in the spec, why is there a printf in rakudo ?
TimToady flussence just pointed you to printf in the spec

Radvendii hey guys 18:24
i found a (maybe) bug
nom: my $a="foo"; 0 && $a="bar"; 18:25
p6eval rakudo 42695e: OUTPUT«Cannot assign to a non-container␤ in block <anon> at /tmp/N7zBzIaBSN:1␤␤»
Radvendii nom: my $a="foo"; 0 && ($a="bar");
p6eval rakudo 42695e: ( no output )
Radvendii shouldn't = be lower precidence than &&?
benabik it is.
So (0 && $a) = 'bar' 18:26
Radvendii sorry
colomon which is 0 = 'bar'
Radvendii i meant higher precidence
benabik no...
$a = $foo && $bar
Radvendii oooh
good call
benabik There's `and` and `or` for low prec versions
Radvendii and you can't have different precidence for lvalue and rvalue? 18:27
benabik nom: my $a = 'foo'; 0 and $a = 'bar'; say $a
p6eval rakudo 42695e: OUTPUT«foo␤»
Radvendii benabik: ah! thanks, that helps.
:D
benabik I supposed you _could_ have different precedence for l and r sides... but I think that would get more confusing than needed.
Radvendii yeah 18:28
i think you're right
am i guaranteed that .grep will run through a list in order? 18:31
or is that subject to different implimentations?
wait… grep is lazy, so if i do @list.grep(...)[0] it will go through the list in order until it finds a match… 18:32
18:32 icwiener joined
TimToady grep is ordered by default unless you put it into a hyper context (or the new race context, which also unorders the results) 18:34

japhb In the JSON::Tiny module, there is a commit by colomon that split 'rule array' into two rules, array and arraylist, and said that while this should be equivalent, in practice Niecza is much happier with the split rules. Does anyone remember what that was about? 19:05
