cale2 I actually kind of like how perl5 didn't have subroutine signatures. I didn't realize that aspect of it before. Makes the language feel pretty weird/minimal 01:57
02:04 llfourn joined 02:09 llfourn left 02:10 skids joined 02:14 Sgeo_ joined
geekosaur perl 3 was fairly minimal, actually. it just got a lot of stuff layered on top without much attention to rational language design :) 02:15
perl 5 even corrected some of that, before spending a couple decades collecting its own cruft 02:16
02:16 Sgeo left
cale2 geekosaur: comparatively, how do you see perl6? 02:17
geekosaur a badly needed rationalization, but also fairly experimental in a number of ways (and I fully expect the experiments to evolve and change --- in fact this has already happened a few times before release) 02:18
02:21 Beginner_don is now known as beginner_guy
beginner_guy perl6 is a rock. perl6 is an island. but typing .pl6 makes me hurt and cry 02:22

hi beginner_guy

beginner_guy hiya! 02:27
atweiden-air in testing parametric roles with `is-deeply`, i'm getting this recurring issue where the output is identical but the tests fail 02:28
when i switch to testing with `is`, this is the output
expected: 'Header[Int]<140620794464128>'
got: 'Header[Int]<140620794464088>'
whatever that number is, it is consistently off by 40
cale2 just type .pl or .pm and include use v6 :P 02:30
anyone read the early release of Think Perl 6 yet? 02:31
02:33 Actualeyes left
atweiden-air for now, i'm using a custom `sub infix:cmp` as a workaround: 02:35
github.com/atweiden/finn/commit/e4...0ef46469d6
but i've tried golfing it to no avail, so maybe i'm missing something 02:36

b2gills &is checks if two values stringify the same, &is-deeply checks if the data-structures are the same, but only goes into Hash/Array/Set etc. You may want &cmp-ok 02:40

alphah Hello!, Not sure if this is the right place to ask (hope it is), I'm new to programming, What do i need to change to not get "can't lookup attributes" error when executing this code: p6: class Check {has $.item}; class Waiter { has Check $.check; method order {say $!check.item}; }; Waiter.new.order 05:22
geekosaur you need to initialize .check somehow to an actual instance of Check; right now it's initialized to the type object, which is a typed "undefined value" 05:25
you probably want a TWEAK submethod for this (see the end of docs.perl6.org/language/objects#Ob...struction) 05:26
you'll also have to consider how to initialize $!item in a Check 05:28
05:29 khw left
alphah Thank you, I see the issue now, that worked: 05:30
class Check {has $.item}; class Waiter { has $.check = Check.new; method order {say $!check.item}; }; Waiter.new.order
I will review the docs again, I was under the impression that if I defined attribues with $. it will be initialized 05:31
geekosaur no, that just means that an initializer method is created 05:33
which is to say, you can use $.check from outside the class 05:34
05:34 CIAvash joined
geekosaur it does not guarantee initialization in and of itself 05:34
(think: getters and setters)
alphah got it, Appreciate it. 05:37

samcv m: my @array; say @array.defined 05:46
camelia rakudo-moar b51a55: OUTPUT«True␤»
samcv why does this give True :(
are arrays always defined
i have an optional array argument for a routine. i guess i will need to make it a $ sigil?
CIAvash m: my @array; say ?@array 05:49
camelia rakudo-moar b51a55: OUTPUT«False␤»
geekosaur perl 5 does/did (they deprecated defined on arrays, iirc) the same. the distinction in p5 used to be an internal detail (whether the vector to hold possible elements had been allocated or not) 05:52
basically .defined is not a proxy for .empty 05:53
er `not .empty`
06:10 llfourn joined
samcv i just expected an optional parameter that's an array wouldn't be defined 06:11
if it wasn't supplied
06:15 llfourn left
samcv m: my $s = (1,2,5,5); my @array = $s; say @array.perl 06:16
camelia rakudo-moar b51a55: OUTPUT«[(1, 2, 5, 5),]␤»
samcv and this is odd
i would assume it would copy it, not make an array of arrays
any way to stop it from doing that? 06:17
geekosaur I wouldn't. $s is one item, that happens to be a list
m: my $s = (1,2,5,5); my @array = @$s; say @array.perl
camelia rakudo-moar b51a55: OUTPUT«[1, 2, 5, 5]␤»

Todd_ okay I give up. Google is failing me here. how do I do a multi line comment? Google give me "opinons" on Perl 6 06:39
06:40 bjz joined
Todd_ Is the this the right translation of Perl 5 to Perl 6? p5: for my $Line ( @SystemCtl ){ print "$Line\n"; } P6: for @SystemCtl -> $Line { print "$Line\n"; } 06:41
CIAvash Todd_: docs.perl6.org/language/syntax#Mul...d_comments 06:42
Todd_ that was easy! Thank you! 06:44

Todd_ that p5 p5 for loop worked. 06:49
p5 to p6 worked
You guys have a link to p6 patter matching. I am trying to trnaslate a P5 06:51
if ( $x =~ /y/ ) {do something}
06:51 RabidGravy joined
CIAvash Have you tried searching in docs.perl6.org ? 06:54
There are 5to6 docs that can help you docs.perl6.org/language/5to6-nutsh.../_Regexp_) 06:55
Todd_ Yes! I got nowhere!
CIAvash also docs.perl6.org/language/regexes 06:57
you can see a list of those pages on docs.perl6.org/language.html 06:58
samcv Todd_, you want regex?
$x ~~ /blah/
some of the things are different though
Todd_, docs.perl6.org/language/regexes
also welcome to #perl6
06:59 ssotka left
Todd_ Thank you! 06:59
I am trying to fix this:
if ( $Line ~~ m/${ServiceName}⏏/ )
samcv what is ${ } in perl 5 mean to uh
what does that do
in perl 5?
access $ServiceName?
and is there just text in $ServiceName or a regex text string? 07:00
Todd_,
Todd_ in p5 ${x} is the same as $x. The brackets are when yo are string a lot of variable together and you want to remove any misunderstanding 07:01
samcv ah ok
Todd_ Let me try without then
samcv you can just do /$variable/
which will do literal text
~~ / blah / is like m/blah/s in perl 5, spaces are not significant. but with /$vriable/ they are i think it's like \Q blah\E in perl 5 07:02
Todd_ $Servicename will vary. Right now it is "CimTrakAppServer.service"
07:02 Tonik left
samcv also you can do {$blah} 07:02
you can even put code in there if you wanna go crazy, more useful when doing grammars
m: say 'a' ~~ /{say 'hi'}/ 07:03
camelia rakudo-moar b51a55: OUTPUT«hi␤｢｣␤»
samcv heh
m: say '1' ~~ /{3 - 2}/
camelia rakudo-moar b51a55: OUTPUT«｢｣␤»
samcv oh well thought that may or may now work
Todd_ What I am after is if "$ServiceName" exists inside $Line, then Bollean true
samcv well it will evaluate to true
m: say '1' ~~ /1/ 07:04
camelia rakudo-moar b51a55: OUTPUT«｢1｣␤»
samcv m: say so '1' ~~ /1/
camelia rakudo-moar b51a55: OUTPUT«True␤»
samcv you can use so to find out what it would be bool as, or as a method call would be .Bool
you don't have to worry about that if it's in an if statment or somtehing
since it evals as boolean already
Todd_ I just meant do the contents insdie the {}. if {} else {} etc. 07:05
samcv m: my $ServiceName = 'tools'; say 'blahtools' ~~ /$ServiceName/
camelia rakudo-moar b51a55: OUTPUT«｢tools｣␤»
samcv m: my $ServiceName = 'tools'; if 'blahtools' ~~ /$ServiceName/ { say 'found servicename' }
camelia rakudo-moar b51a55: OUTPUT«found servicename␤»
Todd_ if $Line ~~ /$ServiceName/ 07:07
is no longer giving me a syntax error. Problem. it doesn't work. passes everything.
sub GetServiceStatus ( $ServiceName ) {
my @SystemCtl; 07:08
my $Status;
for @SystemCtl -> $Line {
f $Line ~~ /$ServiceName/ {
print "$Line\n";
}
return $Status;
}
geekosaur can I suggest using a pastebin of some kind? lpaste.net, gist.github.com, dpaste.de, ...
Todd_ I refuse to use grep! 07:09
that is "if $Line". I cut off the "i"
07:11 llfourn joined
Todd_ I am thinking I have the wrong syntax for using a variable inside the // 07:12
what is a pastebin?
07:13 stmuk_ joined
moritz it's a service where you copy&paste code into, so that you only have to give us the URL, not paste many lines on IRC 07:14
Todd_ okay
geekosaur also most of them provide editing, and many of them have some way to let other people make their own changes and show the changes as diffs or etc
Todd_ Any idea what I am doing wrong with "if $Line ~~ /$ServiceName/ {}"? 07:15
geekosaur (gist and lpaste offer that last feature)
07:15 stmuk left
moritz Todd_: what's in $Line? What's in $Servicename? 07:16

Todd_: if you expect a line to match, what's in that line? 07:18

moritz NO
not "stuff like"
Todd_ time-sync.target loaded active active System Time Synchronized
moritz copy&paste one *actual* line that you want to match CimTrakAppServer.service

07:22 bjz left
moritz Todd_: if it matches everything, it's likely that $ServiceName isn't what you think it is 07:22
Todd_ I will print it out and check
This is what I am trying to do written in bash 07:23
$ systemctl -la | grep -i CimTrakAppServer.service
moritz try this: say $ServiceName.perl;
before the regex match
what does it print?
Todd_ print "$ServiceName\n"; 07:25
gives
CimTrakAppServer.service
moritz that's not what I asked you to print
Todd_ which was what was expected
moritz but if you don't want help, fine
Todd_ oops
print "$ServiceName.perl\n" 07:26
CimTrakAppServer.service.perl
07:26 bjz joined
Todd_ what did that tell you? 07:26
moritz that you still didn't do what I asked you to, and that it's not worth my time trying to help you further 07:27
masak Todd_: `say $ServiceName.perl;` is the statement moritz asked for. not the print statement you used. 07:28
Todd_: there's a certain technique to getting good help. you haven't mastered it yet ;)
Todd_ Oh poop. the array has line feed in it. Maybe my loop is one long line!
masak moritz: what was the term, "help vampire"? 07:29

moritz irclog.perlgeek.de/perl6/2017-02-15#i_14105627 07:30
geekosaur I don't think that was fair, tbh. this is someone who is quite new and apparently interpreted what you asked for in terms of what they currently understand 07:31
moritz geekosaur: asking somebody to put in a debug statement isn't fair?
Todd_ say $ServiceName.perl;
"CimTrakAppServer.service"
moritz geekosaur: being annoyed that them failing do so so *twice* isn't fair, even though copy&paste exists?
geekosaur mopritz, are you looking for excuses to argue? 07:32
*moritz
moritz geekosaur: I try to help lots of folks in my free time, free of charge. I think I can be picky about when I stop giving that support
geekosaur is gradually getting better at recognizing when he's in that kind of state and backing away from the keyboard
masak .oO( and that's how #perl6 turned into #perl )
geekosaur: I know what you mean. 07:33
geekosaur without, y'know, maligning the other person
moritz I can stay away if that's what you want me to do
07:33 moritz left
masak :( 07:34
Todd_ Figured it out. I put a line counter in my print line. My array is all one line. So, of course my test would find it 07:35
so then, what am I doing wrong in this line that doesn't give me an array of line? 07:36
@SystemCtl = qx ( systemctl -la ) ;
what I am erally getting back is a single string.
El_Che /usr/local/pulse/PulseClient.sh: line 413: rpm: command not found 07:37
<-- the ubuntu package of pulse vpn client
Todd_ Perl 5 converted tht to an array of line of text. Do I have to tell perl6 to do that?

Todd_ what do you mean? 07:44

geekosaur @SystemCtl = qx( systemctl -la ).lines ; 07:44

I am not gettig the difference beteen the perl5 split and perl6 07:58

expecting any of: term
geekosaur regexes in perl 6 act like perl 5's /x modifier
Todd what do you mean? 08:00
geekosaur m: say so 'a b' ~~ /<:space>+/ 08:01
camelia rakudo-moar b51a55: OUTPUT«True␤»
geekosaur literal spaces are not significant in regexes normally

camelia rakudo-moar b51a55: OUTPUT«True␤»
geekosaur m: say so 'a b' ~~ /' ' +/
camelia rakudo-moar b51a55: OUTPUT«True␤»
geekosaur so you can format it for readability instead of the usual chunk of incomprehensible glyphs of old-style regexes
also so you can do things more like parsers: you can define your own tokens and match them with angle brackets 08:03

if you do, you are passing the list as a single parameter iirc 08:13

Too few positionals passed; expected at least 2 arguments but got only 1
What is "Too few positionals passed"?
geekosaur you have passed a single parameter, which is a list consisting of a regex, a scalar variable, and a number 08:15
Todd split ( /<:space>+/, $Line, 6);
geekosaur you have this foul habit: function (parameters)
don't do that
it must be: function(parameters)
or it will be taken as a single parameter which is a list 08:16
Todd docs.perl6.org/routine/split
08:16 xinming_ joined, rindolf joined
Todd lots of () in that. What should I remove 08:16
geekosaur the space
not the parens
split(...) 08:17
not split (...)
ufobat its split() vs split()
oups
geekosaur they mean different things
do not write a space after the function name
ufobat (some,thing) <- is a List
so split (...) is split <SomeList>
Todd I am lost.
ufobat so youre passing this list as one parameter 08:18
geekosaur do you see the difference between "split()" and "split ()"?
08:18 llfourn left
geekosaur there is a space after the word "split" 08:18
*that space* is your error
Todd the space after the "t" in split?
geekosaur yes
ufobat aye
geekosaur you can't do that in perl 6
because if you do, you are giving split a single list argument instead of 3 different arguments 08:19
Todd YIPPEE!!! Thank you!
taking out the space works perfect.
08:19 xinming left
Todd split( /<:space>+/, $Line, 6 ); 08:20
geekosaur this is how perl 6 resolves a conflict in perl 5, where writing a function that takes a list without using parentheses gobbles everything after it
Todd So in Perl 6, I have the bad habbit of adding a space after the function name. I will reform!
geekosaur (so we all got used to writing with parentheses whenever there is a chance of that happening) 08:21
perl 6 replaces it with the new behavior, but now you have to be careful about a space between function name and parameters
Todd Thank you! 08:22
bye bye for now. you guys are saving my butt
my $IAm = qx ( whoami ); 08:31
needs the space after the qx. Is that an exception?
also, how do I get rid of the line feed? chomp( $IAm ) doesn't work 08:32
DrForr Yes, because otherwise it tries to call 'qx' the function. 08:33
Todd okay
08:34 jonas1 joined
Todd I also figured out chomp. it is $IAm=chomp($IAm) 08:34
The original is not modified as in perl 5
DrForr Yep, it *is* a different language.

Todd P5's subs drive me around the bend. It is suppose to be a high level languare, but it passes variables to subs in @_. Can we say "assembly code". I can't wait to learl Perl 6! 08:37

DrForr method foo( $x, $opt=1, $str where 3 < * <= 18 ) { ... } 08:38
El_Che Todd: sub signatures should be in core in the next release. For now, use experimental: search.cpan.org/~shay/perl-5.24.1/p...Signatures 08:41
Todd wht is different about that tha what I am subbently doing. I blab away inside the sub's () 08:43
how do I put a sub inside an if statement? 08:44
if ( not GetServiceStatus ( "CimTrakAppServer.service" ) eq "active" ) {

Todd an error is not thrown, but the proofing statement inside the sub lets me know it never got called 08:45
08:46 bjz joined 08:47 xtreak joined
samcv Todd, sub inside an if statement? calling a sub or declaring one? 08:47
DrForr Better written as 'if GetServiceStatus("...") ne "active { }' IMO :)
samcv yeah you don't need parens in perl 6 08:48
DrForr Parentheses are even more optional.
samcv are they optional in perl 5?
i know they are if they come after something
say 'blah' if 'foo'
DrForr They are in perl 5 to a certain extent too, Perl 6 takes that to a new level :) 08:49
samcv Todd, perl 5 sorta has signatures but you have to enable experimental features. apparentnly been around a while. but. dunno why still it is experimental
Todd the code I am converting uses them.. Don't know if it is optinal or not. I do know you'd better put a space after the "(" or your get the finger wagged at you
samcv DrForr, did i hear something about perl 5 able to type signatures? or am i misremembering
Todd YIPPEE!! the extra paranthsis was the issue 08:50
DrForr Typed signatures? *maybe* Function::Signatures, but when p5 borrowed ~~ they didn't bring the type system with them, and that's what caused its downfall.

samcv :) have you seen learnxinyminutes.com/docs/perl6 ?
i contributed to some of that, so it is pretty good i think. i mean not perfect. but it's a very good starting point

perlpilot masak: Just hop in your time machine and go to the future and ask yourself what the solution is.

masak perlpilot: you remind me of something Kent Beck said on Twitter a while ago. 13:48

"I often find it useful when I need to go back and correct things to ask myself 'what would have been the perfect message from my future self about this problem?'" 13:49

lucasb about ticket RT #130787, when you need to bind a pair to a positional parameter, you can type func('a'=>1) or func((a=>1)), because plain a=>1 would be considered a named parameter, right? should this same behavior be honored inside sub-signatures? I guess it should. 16:35

IOninja I volunteer RabidGravy for the task :) 21:06
cale2 first task is simply to get the same exact thing working with the perl6 executioner 21:09
That's the part I need help with

cale2 Test::More is basically the same as Perl6's Test, so that's nice 21:11

perlpilot cale2: you might want to do something wrt "Copyright (c) 2012, Salesforce.com, Inc." 21:14
cale2 perlpilot: I thought it was a bit odd. Apparently SalesForce uses Perl. And they love it so much they used their own name in the copywrite of these Koans... 21:16
in any case, it says you can do whatever as long as you keep the copyright in the file
perlpilot no, it says "Redistribution and use in source and binary forms, with or _without_modification_, are permitted provided ..." 21:17
oh I can't even read myself :) 21:18
in any case, I if you change the whole thing (which you will end up doing) is it the "same work"?

perlpilot can't type either 21:19
eh ... just ignore me. My brain is obviously not fully engaged. 21:20

cale2 I'm gonna suggest we keep that in there regardless of how many changes are made haha 21:23

Allow passing in file names on the command line.

doc: 9db61a98b5 | (Will "Coke" Coleda)++ | xt/examples-compilation.t
Only have to verify it's compilable.

Don't bother actually running the code.

samcv dammit i still can't get proc::async working for this one program. working fine for echo 22:32
and i can run it in terminal fine and type in the input
err i meant cat 22:33
but yeah ugh

samcv i can't seem to see any of the stdout output 22:35
cale2 samcv: do you have a gist of it? of glot.io link? 22:36
geekosaur is the program still running?
cale2 ^ if it is, you should probably catch it...
geekosaur (programs writing to pipes buffer. you can try using stdbuf to alter this)
samcv gist.github.com/d77abc42255b56ca68...769ac12d7e
this is all i'm doing
and it's my own program. and it was running when i checked ps 22:37
can't even see the printf output that it does on program start
i should be able to see it due to the tap
geekosaur yes
and no
samcv what must I do
write to stdbuf? 22:38
geekosaur stdbuf --output=0 ./build/bitfield
samcv how can i change the program to not need it?
fprintf(stdbuf, or what
22:39 llfourn left
samcv ok that worked geekosaur 22:39
geekosaur setvbuf(stdout, 0, _IONBF 0)
er
setvbuf(stdout, 0, _IONBF, 0)
or equivalently setbuf(stdout, 0) 22:40
(the former is more standards-compliant, the latter historical but very widely supported)
both tell the program not to buffer its output (and the stdbuf invocation forces this from outside, via LD_PRELOAD hackery iirc) 22:41
samcv so c programs using printf are going to be bufffered? 22:42
unless you do this?
geekosaur when writing to anything other than directly to the terminal, yes 22:44
basically stdio's fopen does isatty(opened fd) and sets line buffering if true, block buffering if false
because both are faster than unbuffered 22:45
22:48 cale2 left
samcv how can i force line buffering? 22:49
22:52 girafe left
geekosaur setvbuf(stdout, 0, _IOLBF, BUFSIZ); 22:59

[Coke] samcv: ISTR we documented that on the doc site. 23:50
samcv ISTR? 23:51
[Coke] bah. docs.perl6.org/type/IO$COLON$COLON..._terminals but it doesn't actually say how 23:52
samcv should have a link to it on Proc::Async
[Coke] ... and that seems to indicate the default is buffered. ah well.
ISTR is "I seem to recall"
geekosaur you also can't control what buffering a program you spawn uses, except via stdbuf *if* the program uses libc + stdio 23:53
