ugexe Something about t/02-rakudo/04-diag.t does not like to work with some combination of testing a) pre-make-install, b) testing with prove, and c) using prove with `--archive`, but i'm not immediately seeing anything suspect jenkins.p6.nu/job/rakudo/7/os=linux/tapResults/ 00:33
00:38 Rawriful left
ugexe `- diag at the start of file shows up in non-verbose prove run` - this doesn't seem like something that should be tested 00:52
eh its not actually testing prove 00:55
01:02 ryn1x left
ugexe ah its because it essentially does `$*EXECUTABLE -e 'use Test; ...` which is not valid unless its already installed or it passes the current $*REPO to the $*EXECUTABLE 01:03
leont I remember seeing similar issues in the spectests for Test.pm, they fail when you don't have any rakudo installed -_-
ugexe almost seems like a $*EXECUTABLE-BUT-WITH-MAH-LIBS would be useful
leont (no idea if that got fixed in the mean time) 01:04
ugexe i havent gotten to prove-invoked-spectest yet, but hopefully that was fixed 01:06

araraloren_ timotimo, thanks
yeah, please

timotimo the 'if $f ne "." | ".."' might go through actual junctions if my junction optimization doesn't catch it, so that might be significantly more expensive than $f ne "." && $f ne ".." 12:56
if you turn %ext into a Set up front your (elem) will be much cheaper because it won't have to recreate the set over and over again 12:57

El_Che moritz: your book arrived today :)
timotimo so your script will just be "use FindTheFiles" and the module would be the contents of what is now the script file

timotimo btw
and yes, $++ on an undefined value (what $ starts out containing) will return 0 rather than whatever undefined value was in $ before
because you're using it as a number, so having 0 as the starting point makes sense
HoboWithAShotgun no i got bitten by it not getting reset to zero after the loop. so when i tried to ran that loop again it didn't work because $++ still had the value of the previous use 15:48

camelia 5===SORRY!5=== Error while compiling <tmp>
Undeclared routine:
greet used at line 1. Did you mean 'grep'?
comborico1611 I think that's a little too advanced for me to understand right now. 16:11
ufobat i dont know if this is true, but if you ask me i'd find it strange to have a $scalar for a sub
basically you can delcare subs inside subs 16:12
comborico1611 For sure.
ufobat as you declare my $variables;
and they have a lexical scope, which means you can only use them within your (current) sub
and with that you could maybe avoid storing a anon sub in a $scalar 16:13
just as an idea
comborico1611 I agree (from what i can understand). Using confusing code is not good.
ufobat sub foo { my sub greet { say "hi" }; ...; greet() }; <-- you see sub greet is delcared inside foo 16:14
so you can use greet() only inside foo
comborico1611 Yes. Local scope.
ufobat that's what i mean :)
comborico1611 Gotcha. Thanks for the tips! 16:15

Voldenet I wonder if there's any good way to get the critical {} working 17:20
using Lock.protect sounds good enough, I'm just wondering if I can use some global namespace for magic "critical" keyword 17:22

camelia 0.343150
ugexe shouldnt use state var for locks 17:25
Voldenet Okay. But why? 17:26
ugexe its not thread safe to do since its at least two non-atomic operations, //=, (is this defined) -> (if not then define it) 17:27
so you could get two threads hitting it before its defined
17:27 ChoHag left

camelia 0.3735283
ugexe or something like that. so generally you just put it as a lexical or a attribute
Voldenet that'd be better, right? 17:28
ugexe yeah i think that is ok
Voldenet thanks

tailgate Hi, I'm trying to set up zef on OSX. I installed it with rakudobrew, and packages install sucessfully. However, if I atempt to use a package i installed, I get Could not find Text::CSV at line 1 in: (list of folders) 18:32
what do I need to change to get this working?
[Coke] tailgate: works fine here; do you have multiple versions of rakudo installed with rakudobrew? 18:34
tailgate I installed previous versions. Is there a way to check that?
I used homebrew
[Coke] ... homebrew, or rakudobrew?
I'm testing Text::CSV right now in case there's something weird about that module in particular. (works for me in general though, using a single installed rakudo version in rakudobrew and using zef as my module installer) 18:35
when you install a module, it's for that named version you installed with rakudobrew; so moar-2017.10 might have it, but moar-2017.09 could not. 18:36
(yup, that module works fine)
tailgate yeah, I think I have something screwed up on my side 18:37
[Coke] so could be version skew in rakudobrew; could be a typo in your use: $ perl6 -MText::CSV -eNil; will test that one module.
18:37 Cabanossi left

18:39 troys joined
tailgate [Coke]: I figured it out. I need to run rakudobrew init and put rakudo in my PATH 18:39
so I just need to set up my shell's init 18:40
HoboWithAShotgun anyway, the put line above complains about the signature not matching.
ugexe because :in does not take a command to run
18:40 Cabanossi joined
ugexe you give it a handle 18:40
[Coke] tailgate: ah, so maybe were testing with a different perl6 than the RB one. 18:41
tailgate Im using homebrew's rakudo-star 18:42
ugexe my $tee = shell "tee", :out, :in; and :in($tee.out) + $tee.in.put(...) or some such
[Coke] so no rakudobrew at all?
tailgate no, I have it installed.
rakudo init fixed it
[Coke] ... rakudo-star and rakudobrew are two completely different things. you have both? 18:43
tailgate yeah
18:44 wander joined, geospeck left 18:46 setty1 joined
tailgate The zef instructions said to use rakudobrew 18:47
[Coke] if you're using zef via rakudobrew, then you're not using rakudo-star anymore. 18:48
18:48 TimToady joined 18:49 zakharyas left
tailgate hmm. If i uninstall rakudo-star, my perl6 command is gone too 18:49
[Coke] rakudo star comes with zef, a bunch of modules pre-installed...
ugexe well, if you have a rakudostar installed and also rakudobrew its possible for the rakudobrew perl6's zef bin to use the rakudo star lib of zef (old)
[Coke] tailgate: ah, trust ugexe over me, they wrote zef. 18:50
tailgate Is it better to install zef manually or rakudobrew? 18:51
ugexe if you do `zef --help` it will show you the path of its configuration file
that should show you if the correct zef is being used
[Coke] tailgate: again, you should have already had zef installed from star.

HoboWithAShotgun how do i create a rx// with a :g modifier? 19:30
19:31 ryn1x joined
HoboWithAShotgun i tried $something ~~ m:g/$rx/; but that only matches once 19:32
moritz huh 19:33
m: my $re = rx/./; say 'abc' ~~ m:g/$re/ 19:34
camelia (｢a｣ ｢b｣ ｢c｣)
moritz seems to match three times, as expected
huf *can* g be part of the regex (and not the application of the regex)?
moritz no
HoboWithAShotgun allright, mus be something else then
moritz it's a run-time only adverb
huf oh but the original also, silly me

｢foo｣
HoboWithAShotgun what am i missing here, why is the first one not matching? 19:51
moritz strings are interpolated as literals 19:52
you need <$reg> if you want it to be interpreted as a regex
19:55 Cabanossi joined
wander otherwise it is literal 19:57

HoboWithAShotgun i got bitten by something, not sure if it's a bug. This works: hastebin.com/bufudurowu.pl, this doesn't: hastebin.com/abotumajuq.pl 20:14
it's probably that eval trap? 20:16
but i don't see what's wrong with that even if it gets eval'ed
timotimo check what $i has in it afterwards 20:17
probably something much larger than 4
the <{ ... }> code is getting re-run every time the match reaches that point 20:18
m: my $i = 0; say "foo foo foo foo" ~~ / <{ say $i++; "foo" }> /;
camelia 0
｢foo｣		 20:19
HoboWithAShotgun 32

camelia 0
1

4

7
(｢foo｣ ｢foo｣ ｢foo｣ ｢foo｣)
timotimo you'll be matching 0foo | 1bar | 2baz | 3pun the first time
the second time you'll be matching against 4foo | 5bar | 6baz | 7pun
thanks to backtracking and searching for the next possible match it probably won't match 0foo_5barz either. perhaps 0foo_9barz or even later 20:20
HoboWithAShotgun: does the explanation make any sense? 20:23
HoboWithAShotgun makes sense. the code block could return something else at each run
20:28 releasable6 joined
HoboWithAShotgun on a scale of 1 to 10, how terrible is this: hastebin.com/akagikufeg.pl 20:29
(line 12) 20:30
lizmat HoboWithAShotgun: how about "map( { .perl.substr(1, *-2) } )" ? 20:32
HoboWithAShotgun yeah
lizmat haven't tried, but this may also work "map( *.perl.substr: 1, *-2 )" ?
HoboWithAShotgun no, i mean how terrible is it to stringify a regex, strip the // and return it into a combined regex 20:33
it feels there should be a better way to combine regexes
lizmat ah, ok, like that
lizmat doesn't know of a way, but again, that's not saying much :-) 20:34
moritz HoboWithAShotgun: well, you can build an array of regexes in the form rx/ $i $previous_regex /
20:34 philomath joined
moritz and then interpolate the resulting array 20:34
HoboWithAShotgun huh? 20:35

moritz HoboWithAShotgun: perlpunks.de/paste/show/5a0a02db.1736.259 20:38
in Perl 6, regexes are much more like code than they are strings 20:39
ugexe m: my $a = /a/; my $b = /b/; my $ab = /<$a> <$b>/; say "a" ~~ $ab; say "b" ~~ $ab; say "ab" ~~ $ab; # i already typed this so damnit im pasting it
camelia Nil
Nil
｢ab｣
moritz so you should the approach transforming regexes much like you would transforming code 20:40
by embedding it in closures
m: my $a = /a/; my $b = /b/; my $ab = /$a $b/; say "a" ~~ $ab; say "b" ~~ $ab; say "ab" ~~ $ab;
camelia Nil
Nil
｢ab｣
moritz no need for <$foo> if $foo already contains a Regex object
