lizmat "$ = $ for $primes" ?? am I missing something ? 01:00
Zoffix: ^^^
Zoffix lizmat: dunno. Why do you think you're missing something? The idea is nqp::null for $primes
lizmat shouldn't that be "$_ = $_ for $primes" ? 01:02
01:02 astronavt joined
Zoffix lizmat: doesn't matter. The problematic bit is the `|$primes` iteration itself, not what the for loop does 01:02
I just don't know anything better than `$ = $` for a null operation that doesn't emit a warning 01:03
lizmat then maybe "Nil for #primes" ?
*$primes
Zoffix m: Nil for <a b c>
camelia ( no output )
Zoffix How come that doesn't warn?
lizmat special cased afaik
Zoffix lizmat++ that is indeed better 01:04

camelia 97
geekosaur it found the lexical max
not the numeric one
Herby_ doh 05:50
geekosaur you use split, it produces Strs
Herby_ what would be the clean way to do that, given a string?
simple for loop?
teatime m: my $line = "86 440 233 83 393 420 228 491 159 13 110 135 97 238 92 396"; say $line.split(/\s/)Β».Int.max()

Todd HI all, A dumb question (but that never stopped me!) 07:16
Why does this work: $cmd = "/usr/bin/atop 1 1 > $GoodATop 2>&1"; $str = qqx{ $cmd };
but including the string on the qqx lie does not. Why do I need to use a variable? 07:17
symptom: /bin/sh: /usr/bin/atop 1 1 > /opt/Cimcor/CimTrak/CimTrakServer/logs/atop.txt: No such file or directory
$str = qqx{ "/usr/bin/atop 1 1 > $GoodATop 2>&1" }; doesn't work 07:18
teatime that's not getting shell quoted
or rather, I think it is, but you put it in "" which get passed to the shell :)
Todd Oh, so leave the quotes off?
teatime try: $str = qqx{ /usr/bin/atop 1 1 > $GoodATop 2>&1 }; 07:19
yeah. qqx{} is itself the quoting construct
Todd Bugger. Thank yoU!
worked perfectly Thank yoU! 07:20
teatime excellent.
Todd This one worked too! 07:22
my $str = qqx{ cd /opt/Cimcor/CimTrak/CimTrakServer; ./CimTrakServer.exe -Diagnostics \"Level=255\" > $GoodCimDiagErr 2>&1 };
07:22 wamba joined
Todd Will wonder ever cease! 07:23
geekosaur I think the backslashes are unnecessary there
teatime do you even need to escape
yeah
geekosaur in a "" string theyd be needed but here the quotes are { }
so they unescape to "
also I can't imagine $str contains much useful after that since you send it all to a file 07:24
Todd ordinarily no, but the program required it for some reason.
It is ported from that "other" operating system, whose name I can not mention. 07:25
geekosaur qqx does because it's an expression. you probably wanted
teatime Todd: VMS?
geekosaur shell " cd /opt/Cimcor/CimTrak/CimTrakServer; ./CimTrakServer.exe -Diagnostics \"Level=255\" > $GoodCimDiagErr 2>&1 "
and here you do need the escapes 07:26
teatime well only because you chose to use " " ;)
geekosaur also note that, as with perl 5's ``, using qqx when you don;t need the output is kinda expensive
yes, I could have used Β« Β» or something instead 07:27
also, uh, good luck running that on VMS :p
directories don't work the same way, redirection requires something that looks more like JCL than Unix 07:28
teatime looks at geekosaur.
geekosaur (yes, I know. ironically that'd actually stand soem chance of working as is on modern windows)
teatime oh, the command line
geekosaur simple Bourne-shell-style redirections have worked in cmd.exe since windows nt 3.5 and win98 (win95 had a few more limitations but I think that one did work) 07:29
ok, modulo the slashes needing to be backslashes in cmd.exe 07:30
teatime heh
Todd This is Fedora 27. I need the quotes and backslash when run from the (bash) command line too. I was warned by the program's tech support. It also has to run in its own directory too. Weird, but .. 07:31
geekosaur oh, one of those programs. bad win port 07:32
in that case I would actually be surprised that the qqx one worked because perl would strip the backslashes before it went to the shell
Todd I asked this last time, but has anyone come up with a better perl 6 for win 32? I really do not want to use Perl 5. 07:33
geekosaur last I heard the win32 build reliably ran out of memory
while building 07:34
Todd I got the above to work trial and error. I had the 2>&1 redirect wrong and you guys helped me figure it out.
geekosaur might be fixable but I don't think we have anyone working on perl 6 who has a win32 setup
(like, I have a windows vm always running but it's 64 bit) 07:35
07:35 anant joined
Todd that is what I heard. Any way to build a win32 msi on a 64 bit system? 07:35
anant Does perl6 support nested classes?
teatime yes.
geekosaur (and insufficient memory to run a second concurrently, and I use the main one often enough that shutting it down kinda messes things up)
it would have to be a cross-build and I don't think that's currently supported 07:36
Todd bugger.
teatime ... did I just lie
geekosaur (windows has odd restrictions. best bet might be to try to get a wow32 build env; not sure how painful that is.)
nested classes should work fine
Todd anyone know what the P5 equivalent of slurp and spurt is? 07:37
geekosaur but accesses might be funny
Todd When building Wine Staging, I have a "./configure --disable-win64" option. Nothing like that for Perl6? 07:39
geekosaur don't think there is a spurt. slurp is { my $o = select $fh; local $/ = undef; my $r = <$fh>; select $o; $r } assuming $fh is the filehandle (this can be simplified a bit in some circumstances)
anant I didn't an example of a nested class in docs.perl6.org/language/objects
geekosaur that tells wine to not build win64 emulation into it, not that it should build a win32 program
anant I didn't = I didn't see
Todd no sign of either over on perldoc.perl.org/index-functions.html#S
geekosaur it'll generate a 64-bit executable that only handles win32 emulation
m: class A { has $.a; class B { has $.b }}; my $x = A::B.new(b => 6); say 'alive' 07:40
camelia alive
geekosaur so it may depend on what you mean by nested 07:41
since it's mostly namespacing not e.g. need an A to make an A::B
heh. back in the old days FileHandle.pm had a slurp but it looks like current IO::Handle lacks it 07:45
07:45 aborazmeh left
geekosaur I recall it being somewhat discouraged 07:46
although there were two camps on the issue
anant Thanks geekosaur and teatime :)
teatime geekosaur++ 07:47
anant teatime++
geekosaur oh, if you wanted that nested class to only be accessible nside of class A, it's 'my class B { ... }' 07:51
07:53 darutoko joined
anant ok. Are nested classes discouraged in general? I searched many perl6 tutorials, but didn't see them mentioned. 07:53
buggable New CPAN upload: Inline-Go-0.0.4.tar.gz by AZAWAWI cpan.metacpan.org/authors/id/A/AZ/...0.4.tar.gz
geekosaur not so much discouraged as of dubious use 07:54
07:55 Todd left
anant Hmm. Does Perl6 have a "Zen" guide like Python (www.python.org/dev/peps/pep-0020/) 07:56
geekosaur nope.
anant It would be nice to have :) 07:57
I liked how the Python Zen said: Flat is better than nested.
geekosaur python is One Correct Way; perl is There Is More Than One Way To Do It
anant ah!
geekosaur++
geekosaur which is why perl 6 mixes OO, FP, procedural, etc. and lets you mix and match according to need or convenience 07:58
I imagine some conventions will eventually be agreed on by the community, but p6 is young enough that there aren't many such yet 08:00
wander still so many things TODO 08:03
anant Hmm. 08:04

hahainternet .min and .max on an array of strings gives back nonsense results 10:59
Β».Numeric solves it, but I wouldn't expect them to give back such weird outputs 11:00
AlexDaniel hahainternet: why so
hahainternet the strings don't get coerced into the numbers they represent though, i am far too perl6 ignorant to discover why
AlexDaniel m: say <abcdoeu sthiozeu uloeuhal>.max
camelia uloeuhal
AlexDaniel m: say <abcdoeu sthiozeu zzozzzt uloeuhal>.max
camelia zzozzzt
AlexDaniel m: say <abcdoeu sthiozeu zzozzzt uloeuhal>.min
camelia abcdoeu
hahainternet AlexDaniel: i understand
but this kinda violates the whole cool interoperability of strings/numbers in perl doesn't it? 11:01
perl6*
AlexDaniel I don't think so. You gave it a list of strings, and then asked for the max element
hahainternet i actually gave it just a list, never specifying strings 11:02
(semantics i know, but from a programmer's perspective it's important)
geekosaur you have it a list of things that don't look like numbers
hahainternet they certainly do look like numbers
geekosaur if they look like numbers then you get IntStr-s
if they don't then you get Str-s
AlexDaniel what's the code we're talking about?
geekosaur (this means you can actually get a mixture)
hahainternet AlexDaniel: it's just for AOC #2, for 'file'.IO.lines -> $l { my @n = $l.split(/\t/); } 11:03
presumably that produces some sort of hard String type
that won't coerce in a cool way 11:04
AlexDaniel well, you took a string and split it, so you got strings back
geekosaur ^
hahainternet ok, how would i recover the cool behaviour?
geekosaur we discussed thsi earlier, actually, split is a Str operation, it will always give you Strs
AlexDaniel hahainternet: $l.split(/\t/)Β».Cool ? :) 11:05
geekosaur $l.split(/\t/)>>.Int (or that)
AlexDaniel that doesn't work :(
hahainternet AlexDaniel: doesn't appear to exist?
geekosaur: doing Β».Numeric, so that's fine
AlexDaniel .IntStr doesn't work too
hahainternet anyhow not a major complaint, but it felt a bit wart-y 11:06
AlexDaniel lizmat: any reason why we don't have Str.IntStr ?
geekosaur too much magic has its own problems
"every DWIM has a WAT"
hahainternet geekosaur: speak for your own wizardry ;)
geekosaur you say that now...
hahainternet no i know what you're saying 11:07
but it should be up to the programmer to opt in or out to the wizardry they want
and i got opt-outed by default :)
geekosaur because it's easy to opt back in with the hyperop
hahainternet geekosaur: right but it isn't, that only coerces, it doesn't restore the cool behaviour i mentioend
i mean my problem is solved, so ty
geekosaur and you have more control, which matters quite a lot in many cases
geekosaur keeps being reminded of nancy typing 11:08
AlexDaniel hahainternet: but you can also think about performance. That is, should it actually look into every single element returned from .split, and check if it's a number or not?
hahainternet AlexDaniel: if it's an IntStr sure? :)
geekosaur (which was p5's "cool" behavior gone wrong plus a NaN parsing issue)
hahainternet i don't mean the existing case should be changed
i would just like Β».Cool or Β».IntStr as you gave as an example 11:09
AlexDaniel hahainternet: not sure I understand, how would it know if it's an IntStr? :)
hahainternet AlexDaniel: methods are dispatched on types? i'm not suggesting .split or anything do the coercion 11:10
11:10 Aaronepower joined
geekosaur you seem to think a type is determined solely by looking at it. do you really want everything that touches it to have to compute its current type first 11:11
hahainternet geekosaur: where do i think that? I just would like a way to coerce them
11:09.07 < hahainternet> i would just like Β».Cool or Β».IntStr as you gave as an example
lizmat AlexDaniel: I don't see a reason not to have Str.IntStr 11:13
but I would make it slightly more involved than just IntStr.new(self.Int,self), because with that, any error in converting to Int becomes multi-level, and thus complicated 11:15
m: dd "foo".Int
camelia Failure.new(exception => X::Str::Numeric.new(source => "foo", pos => 0, reason => "base-10 number must begin with valid digits or '.'"), backtrace => Backtrace.new)
lizmat as Str.Int returns a Failure, that will explode when trying to bind
so if self.Int returns a Failure, you should throw that immediately, I think
wander m: my $x = IntStr.new(12, "42"); say $x + 4; say $x; 11:16
camelia 16
42
wander the evil way :)
AlexDaniel m: my $x = IntStr.new(12, "I'm not a Str, get off my lawn!"); say $x + 4; say $x; 11:21
camelia 16
I'm not a Str, get off my lawn!
lizmat not too dissimilar from dualvar() in P5 :-) 11:28
handy for things like errno(), where the Str version contains the error message 11:29

the above works
wander mainly about consistency, not have to be kebab-case
poohman token frame {\s*<top_left>\s*\r\n\s*<date_or_time>'</TD>'\r\n}
the only difference is the \s* before \r 11:37
geekosaur because * is greedy and \r and \n both match \s, so you have \s*\s* which is kinda asking for problems
wander what is the text?
geekosaur or put otherwise, you've given that regex *way* too much rope 11:38
wander m: say so "\r\n" ~~ /\s*/
camelia True
wander m: say so "\r\n" ~~ /\s*?\r\n/
camelia True
11:39 espadrine left
wander also note that it's 'token' 11:39
so backtracking is disable 11:40
geekosaur (I oversimplified that a bit; the reality is that it's got far too many ways to match --- and token is ratcheting, so once the first \s* commits to matching the \r\n, it can;t backtrack when it sees the literal ones
poohman ok
geekosaur so (a) since it can;t backtrack, it can't "unmatch" the \r and \n it committed to the first \s* and will fail when it hits them in the pattern (b) and if you make it non-ratcheting, it will be sloooooooooooooooow 11:41

pdcawley jamesnvc: I'm not sure that Emacs has a concept of a <menu> key by default. However, you can pick something (say Key_Menu or whatever) and then use `key-translation-map` to map from whatever emacs thinks it is initially, to `(kbd "<menu>")`, and you should be able to bind to `(kbd "<menu>")` rather than the weird name. 12:20
AlexDaniel pdcawley: that's great to know, but is it the right channel? :D 12:27
pdcawley Arse!
And, it turns out, I'm wrong. Emacs _does_ know about the menu key.
AlexDaniel pdcawley: yeah, it defaults to M-x I think

AlexDaniel just realized he has no menu key

AlexDaniel pdcawley: some keyboard *layouts* are weirder. I remapped my spacebar to AltGr :) 12:32
pdcawley AlexDaniel: Don't talk to me about weird layouts. I've got a KeyboardIO model 01, 64 keys in an an approximation of the Malt layout ('E' on the left thumb, ANIS/THOR on the home row. 12:33
AlexDaniel (or is it other way around? What I meant is that my spacebar is AltGr now) 12:34
pdcawley: oh, that one is cool. Have you seen X-Bows by the way? Another relatively similar keyboard, although it probably doesn't come with a crazy keyboard layout :) 12:35
pdcawley Nope. But I do have an original Maltron that I've cut down to a 64 key matrix, rewired and rebrained to do NKRO and other such stuff, and a Kinesis that I keep meaning to hack palm keys into (and possibly rebrain, but it's got more sophisticated hardware than the Maltron, which was entirely hand wired to begin with. 12:37
AlexDaniel maaaan… keyboardio should really come with perlΒ 6 manual or something :D 12:38

Zoffix: in the advent article, under the "The One And Only" heading, it has a sentence "Since scalars, as the same suggests, contain just one thing… ", should "same" not be "name" there?

pmurias in roast we test tan(pi/2) 13:43
is-approx tan(my num $ = Ο€/2), (sin(Ο€/2) / cos(Ο€/2)) 13:44
is tan(pi/2) something we can expect sane values for

jnthn pmurias: No idea, I thought the "normal" stringification of a float would include all of the available precision? 13:55
If not, maybe we should check why not.
