haxmeister so zef is failing to install Selenium::WebDriver with the following error: pastebin.com/77kKeCHe 01:35
01:36 itsame joined
haxmeister and it locks up there too... have to ^c to get out of it 01:36

lookatme I think it's problem of Selenium::WebDriver. 01:55
The test failed.
haxmeister well I have chromium browser.. and it popped open like 15 windows due to the test
I just installed chrome browser.. maybe it will succeed??.. 01:56
lookatme Is the document of the module said something about test ? 01:57
Such as you have install something .. etc
haxmeister nope 01:58
is chrome test
of some sort
launches chrome windows to nowhere
look at screenshot imgur.com/fRRNZBr 02:02
lookatme I don't know.. 02:04
haxmeister weird eh?
lookatme Em, maybe it's a bug... 02:05
Have you google it ?
02:06 mcmillhj joined
haxmeister no.. I'm digging 02:07
lookatme Em, I notice that have a ChromeDriver, have you installed it ? 02:10
02:11 mcmillhj left, choz joined
choz mornin all 02:11
im newb in perl, anyone knows what is '\$6' in this command do? `perl -e 'print crypt("password","\$6") . "\n"'` 02:12
haxmeister encryption level? 02:13
choz is that a variable?
02:13 Cabanossi left
choz coz when i try to run it, it'd return nothing.. 02:14
raschipi choz: It's not, the "$" is being escaped. 02:15
But I have no idea what it means, though.
02:15 Cabanossi joined, colomon_ joined
choz i see 02:15
anyway, thx fyi raschipi n haxmeister 02:16
MasterDuke_ i think that's the salt. at maybe it's saying to run 6 rounds of crypt?
02:16 colomon left, colomon_ is now known as colomon
raschipi That's another language. There's two with the same name. 02:16
MasterDuke_ *and maybe
choz oh
raschipi We talk Perl6, but that's Perl5.
geekosaur on linux that means to use sha-512 02:17
man 3 crypt
haxmeister $1 would be md5 crypt 02:18
lookatme It's a salt `char *crypt(const char *key, const char *salt);`
choz so \$6 is an ID of glibc salt 02:19
haxmeister $6 sha-512
choz ive got it not
now*
geekosaur lookatme, that interpretation is 7th edition unix
it does more now
haxmeister have to escape the $ for bash to send it proper
choz i think ive got what i have to do next..
tq wizards.. 02:20
geekosaur no, it's single quoted. but it's in a double quoted perl string inside the single quoted shell string, because you can't nest a single quoted string inside another in a shell
haxmeister ^this
geekosaur so it has to escape the $ against perl
haxmeister he's right^
geekosaur (alternately they could have used q/$6/ or something)
haxmeister selenium :(
02:22 mcmillhj joined 02:27 mcmillhj left
haxmeister interesting... it doesnt' like the chromedriver that comes with chromium and to install chromdriver independantly I have to uninstall chromium 02:32
oh the life...
we'll see if it works this time

02:41 mcmillhj left
haxmeister man I have no idea what to do with that information 02:41
MasterDuke_ looks like File::Temp failed a test, but the test has something to do with GC, so maybe it's just a timing error or something like that 02:42
haxmeister I don't even know what GC is referring too 02:43
MasterDuke_ could manually install File::Temp with --force and then try Selenium::WebDriver again
garbage collection
haxmeister ah ok
I'll try again with no changes 02:44
02:44 Cabanossi left
MasterDuke_ yeah, it might be good to create an issue in the File::Temp repo if the test is failing for no good reason 02:45
haxmeister passed temp that time
02:45 Cabanossi joined
haxmeister fingers crossed 02:45
02:46 cpage_ joined
choz just realized my crypt didnt work because i didnt close the last '$'.. finally got it working with `perl -e 'print crypt("Awe378437", "\$6\$"). "\n"'`.. tq for your guys help, really saved me lots of trouble 02:46
haxmeister passed the chrome.t test this time too
02:46 choz left
haxmeister success?!?!? 02:47
lookatme ...
I tried install File::Temp, no error
It's not stable. :) 02:48

lookatme What implementation ? Oh I just test that File::Temp installation 03:37
samcv oh so you aren't usig tnhe module directly
lookatme I don't need that module
samcv oh ok
lookatme Yeah..
samcv Your printf-style directives specify 1 argument, but 1000000 arguments were supplied 03:38

lookatme The temp file will save on the disk ? 03:44

grondilu Hello, I was looking at rosettacode.org/wiki/Bernoulli_numbers#Perl_6, and I tried to shorten it a bit by making @a a state variable. 05:49

that's not the issue. just zoffix is updating the docs to mention 'slurp' instead and that be the preferred one 08:36

samcv lookatme, yes we still have it. but they do *mostly* the same thing 08:57
lookatme samcv, I wonder why they name that method **slurp-rest**.
moritz m: say 1.WHICH.^name 08:58
camelia ObjAt
samcv well. we have slurp now. instead of having slurp and slurp-rest
but slurp and slurp rest literally slurp to the end of the file. but that's basically implied
no reason to say rest
moritz m: class A { has $.x; method WHICH() { ObjAt.new('A') } }; A.new(x=>5) === A.new(x => 6)
camelia WARNINGS for <tmp>:
Useless use of "===" in expression ".new(x=>5) === A.new(x => 6)" in sink context (line 1)
moritz m: class A { has $.x; method WHICH() { ObjAt.new('A') } }; say A.new(x=>5) === A.new(x => 6) 08:59
camelia True
moritz a very egalitarian class
samcv otherwise would be like .slurp-from-beginning or something weird
moritz iirc the question was whether .slurp on a file handle would close the file handle or not
08:59 xtreak left
moritz and the reaction was to rename slurp on file handles to something different 08:59
but why -rest, I don't know 09:00

scovit hello, where could I find the documentation about the behaviour of Closures in Perl 6? 09:29
09:29 xtreak joined, Cabanossi joined
scovit found this en.wikibooks.org/wiki/Perl_6_Progr...d_Closures 09:29
is it possible to introspect the state of a Closure? 09:30
like know which variables are in the scope, what is their value, change their value
lookatme docs.perl6.org/language/functions#Closures 09:31
scovit, check out this page
scovit lookatme, thank you. I would like to know if it is possible to manipulate their state? 09:33

scovit lookatme, I am trying to understand. For packages I understand it might be possible to achieve what I would like, and that is maybe what I should focus on. What about blocks? 10:00
m: sub ciao(&code) { my $j = "due"; say &code::.keys; }; my $i = "perl"; ciao { say "here"; };
camelia (0)
10:00 wamba left
scovit also, could I create a Package on-the-fly as a closure? 10:01
jnthn Perl 6 is pretty strict about lexicals staying lexical 10:04
There's no way in general to introspect what a closure closes over 10:05
10:05 xtreak left
jnthn It is possible to obtain MY:: and pass *that* around 10:05
But the compiler is otherwise free to optimize lexical variables aggressively, including erasing information that would allow their introspection, short of seeing something that requires it in scope (like MY:: or EVAL) 10:06

Zoffix moritz: rt.perl.org/Public/Bug/Display.htm...et-history
and I recall talking about it in #perl6-dev and TT saying it's got to do with curry and chaining or something 11:24
bioduds: in your case you can just remove the asterisk, as the `where` block thunks, so $_ will be the arg and your expression returns True/False 11:25
11:30 zacts left
Zoffix bioduds: also we have UInt for Int >= 0. Though natural numbers generally don't include a 0 so your subset is off a bit 11:30
And the Firstname subset doesn't need the lower bound since chas can't be negative; so just .chars < 256 11:32

if you want complex numbers, you need to start with a complex number

camelia -0.0381123313882117-1.79806329757973i
moritz and it's always[tm] been this way, since we don't want to burden the not-so-mathematically-inclined programmer with complex numbers if they just made the mistaken of taking an sqrt (or comparable) of a negative number 14:06
Ulti yeah I guess that's fair
plus with the precedence just pointed out it might be super confusing 14:07
raschipi What's happening is automatic promotion from Rat to Num, because Rat has limited precision.
FatRat doesn't promote to Num. 14:08
Rat is limited to 64 bits in the denominator.
14:11 khw joined 14:12 Cabanossi left 14:14 Cabanossi joined
[Coke] moritz: it's not complex though. you can cube root a negative real and get a negative real. Is it just complex because we don't have literal cube root and are approximating? 14:16

moritz [Coke]: right, but we disallow fractional powers of any negative number, which is a common practise in numerical implementations
[Coke] hokay.
it was the wrong equation for my particular problem anyway, so I'm all set. :)

TimToady heads to Fry's yet again for more capacitors... 16:45
timotimo did you fry your capacitors?
TimToady ancient Tivo power supply, have replaced most of the caps already, but of course it's the one I forgot to buy that is the busted one, seemingly 16:46
anyway, the 12v line is only making about 6v
can actually hear the cap arcing, a little snick-snick noise 16:47
I wouldn't put so much work into this, except it's the Tivo with the lifetime subscription :)
also put a new capacitor into my air conditioner condenser last week, but that single cap easily outweighed all the boards in my Tivo :) 16:49
TreyHarris TimToady: heh, hope you've stuck ethernet and a bigger hard drive on it if it's old enough for that
TimToady it's the early HD model, so already has ethernet 16:50
TreyHarris Ah... the ones before that had ethernet--as headers on the board. So you could connect it but you had to run a cable through the chassis. Turned out the fan was smaller than the outlet by _just_ enough to get a thin cable out. 16:51
TimToady had an external 500G, but plan to replace internal with 2T and forget the external
I don't think I'd futz with a low-def tivo, since I'm a bit of a video snob :) 16:52

timotimo self.$attr calls $attr as a code object and passes self as invocant 17:49

you don't get an error because you're not calling any of the code 17:51
alphah hmm
tried slef.$attr.new.hello 17:52
timotimo well, as long as it's inside method foo of class B and you're not doin something like B.new.foo
nothing's gonna happen
you won't get a compile error because the $attr that gets passed could be a code object
even though the default case would almost guaranteed give you an exception, we don't do analysis like that 17:53
okay, cat left 17:55
alphah okay, so what I'm trying to do is: I have a class which has 3 attributes , each one is an instance of different class,,, I want to create a method takes "string" arg, and use the instance that matches this string

what confused me is I did not think I will need the "()" for the attributes... now understand 18:01
timotimo yeah accessors are just methods 18:02
that was the number one confusing thing for me near the beginning
alphah noted
timotimo i was like "but the attribute is called $.foo, why don't i write self.$foo or something?
or maybe $self.foo?"
etc etc
alphah yes exactly, that was my thought just 1 minute ago 18:03

jnthn If one of those isn't what you want I need a little more explaining. :-) 21:02
samcv jnthn, gist.github.com/9c08cbff64bb8b21d1...f9e37536f7
i get nothing but an empty list printing out like this
but printing out $/ itself works fine. gisting that is
caps does work though 21:03
jnthn Ah, yes, because <hex> and friends are named captures
That's what I meant by "Positional captures in .list" 21:04
samcv ah kk
jnthn It'll only give those captured like (xxx)
samcv ok i got it. using caps now :)
jnthn Hm, I'm sure I wrote something to parse that file at some point... :) 21:06
samcv yeah we have something to parse the file right now. i'm making it better though :) but yes you have :) 21:07
going to check individual graphemes instead of just the length of the total graphemes now
jnthn yeah, just ofund it
*found it
github.com/perl6/roast/blob/master...est-gen.p6
:)
samcv to make it fully test what the test is testing
i wrote that one you wrote the one before that :) 21:08
haxmeister json module seems to work
samcv in git history somewhere
jnthn And yeah, I was like "wait, how did I get away with such simple parsing code...oh" :D
samcv yeah neither of us did it very complex
tested it 90% which is mostly good enough
unless you have two incorrect in the wrong direction break/nobreaks
unlikely but. 21:09
important to test for
21:09 sufrostico joined
jnthn Yeah, it's nice to have to make sure we're really getting it right :) 21:09
Especially with Unicode 9 21:10
The world was simpler in Unicode ...
*9
gah, 8 :)
samcv heh
the good ol days
jnthn Yeah, the emoji stuff broke the "just examine two codepoints" assumption :/ 21:11
21:12 raschipi left 21:16 kyan joined 21:18 Ven_ left 21:20 Ven joined 21:21 Ven is now known as Guest85403
samcv and prepend 21:21
broke the directional ensurement for state 21:22
maybe didn't use the bset words there
*best
but you get what i mean
i've almost got this :) going to look nice this test 21:23
jnthn samcv++ 21:24
samcv gonna be my best looking one yet
21:25 zakharyas left 21:29 mcmillhj left, Guest85403 left 21:36 perlpilot left 21:45 setty1 left
samcv \o/ success 21:46
21:47 mcmillhj joined
samcv jnthn, might include the test file in roast maybe? it doesn't take very long to process it using a grammar 21:48
jnthn samcv: As in the Unicode test data file itself? 21:50
samcv yeah
jnthn Guess we can...are there any license condiderations? 21:51
*considerations
samcv i will check into that.
jnthn But otherwise, if it's quick enough just to parse and test each case as it comes then may as well do that
21:51 espadrine left 21:52 mcmillhj left
samcv yeah 21:52
just have to make sure to not delete their license information
"this copyright and permission notice appear in associated Documentation." 21:53
so that's fairly simple.
21:57 alimon left, mcmillhj joined 21:58 raiph left 22:01 raiph joined
samcv ok so we have 11 lines that result in failures up from 4 22:01
so yay 22:02
yay failure!
