I heed to use some string-template system. I mean 'Insert to string value by <%= key %>'. I think I can use some regex to find <%= ... %>. But how can I find all that pieces? 05:24
moritz atroxaper: how about using one of the several template engiens found on modules.perl6.org? 05:25
or else, use a global match 05:26
m:g/.../, or $str.match(:g, $regex)
05:27 raiph left

I didn't think to find existent template system. But I'm going to look at them. 05:28

timotimo check that your $PATH is pointing at the correct perl6 perhaps? 06:21
and the correct panda binary as well; especially try head (which panda)
atroxaper $PATH is pointing to all perl6-* and perl6. perl6 -> perl6-m 06:23
timotimo and the hashbang of the panda command? 06:26
atroxaper #!/usr/bin/env perl6 06:28
timotimo can youexplain your problem a bit more?
06:29 erdic left, erdic joined
atroxaper I have installed Template::Mojo by panda install. And now if I write 'use Template::Mojo' and run per6-p I see that perl6 can't find that module. But perl6-m and -j works well. 06:30
timotimo er ... panda should install it for only one of your perl6s
atroxaper And how can I install it for another? 06:31
timotimo the best approach is probably using rakudobrew, you can "rakudobrew switch" very easily
06:31 dayangkun joined
atroxaper Really? Where can I read about that? 06:32
timotimo hmm, good question; the repository with it is in tadzik/rakudobrew
atroxaper Yes. I found it. Reading ;) 06:33
timotimo we should quite possibly propagate information about rakudobrew closer to perl6.org and rakudo.org 06:34

you just can't do much with a shallow clone (a bit better in newer git versions) 09:16
09:19 donaldh left
atroxaper tadzik: moritz: I just clone nqp three times :) And i thought that using --depth can allow to install all three backends faster in first time. 09:19
And that change don't require lots modification in rakudobrew. 09:21
09:23 chenryn left
atroxaper tadzik: btw how can I uninstall panda? I have installed in by bootstrap. And now I install all by rakudobrew but panda runs from previous path. 09:23
tadzik atroxaper: oh, manually :/ 09:24
remove .rakudobrew/<backend>/panda probably
atroxaper tadzik: no. Panda that I've installed by bootstrap.pl ) 09:25
moritz atroxaper: maybe --reference <path-to-existing-repo> would be even faster
git clone --reference <path> # that one
tadzik ah 09:26
09:26 Guest67868 is now known as ponbiki
tadzik atroxaper: well, it got installed to wherever your rakudo was, probably 09:26
'which panda' will tell you

09:27 pecastro joined
atroxaper moritz: yes! It would be best! 09:27

lucas__ Hello channel! 12:39
FROGGS hi lucas__
lucas__ I'm trying to get my head around type constraints. Can you help me determine if the following statment is false or true? "You can only use type constraints in my/state/has declarations and in routine signatures; You can't use it with our and constant declarations and pointy blocks parameters." Did I get it right or wrong?

12:47 pdcawley joined
FROGGS okay, that makes sense 12:47
lucas__ FROGGS: it is good it work in pointy blocks :)
FROGGS "You can only use type constraints in my/state/has declarations and in routine signatures (including pointy blocks); You can't use it with our and constant declarations." 12:48
lucas__: pointy blocks are almost identical to subroutines
12:48 Vlavv joined
FROGGS the only difference is that a return falls through 12:48
lucas__ I was thinking more like "constant Int $x = 42;" But I agree it makes a strange sense to type a constant.

FROGGS m: constant Int $x = 42;

FROGGS it wants to parse a name (or variable), so a type that looks like a name confuses it
12:50 uniejo left
lucas__ yes, S03 says constants can't be used with signatures, because constant declarations already declare names in "type" space. 12:51
I guess only "our" scoped variable remains... 12:52

psch hi brrt 13:20
brrt how is it? :-)
psch i'm poking at Actions.nqp to try and figure out how to make tr/// actually work 13:22
fwiu, in smart-match context tr/// has to set its lhs to the result of .trans with the tr/// arguments as par, but return the number of changed or deleted characters 13:23
so to compare the before and after i have to store the original lhs to the smart match somewhere; i think i have figured out how to do that now
brrt ok.. cool :-) 13:24
psch what are you up to? 13:25
13:31 mr-foobar left 13:33 uniejo left
brrt i'm working on a bug in moarvm 13:39
basically, 'inline and jit doesn't work together very well yet'
jnthn++ has already suggested the right solution 13:40
psch sounds a bit more involved than what i'm doing :) 13:44
13:45 dmol left
brrt no, not really :-) 13:45
just another language :-)
13:45 btyler joined
psch i had had a look at something in moar recently, but got stuck in a spot where FROGGS got stuck as well; that combined with my lack of understand of moar and low confidence in my c knowledge made me put that aside 13:45
brrt what did you want to fix? maybe i can help out 13:46
psch that something was P6int without an explicit nativesize not having the right bitsize
brrt hmmm
psch i.e. on a 32bit machine 'my int $x' instantiates a P6int with 64bit, which is not to spec
brrt what would be the 'right' bitsize according to you?
hmm
psch or rather, it doesn't limit to 32bit
brrt i believe its according to moarvm implementation, yes :-) 13:47
in nqp, my int $x makes a true native int, and those are always 64 bit wide in moarvm, basically because all registers are 64 bits wide
yes, that is a pain point on 32 bits, no, we're very unlikely to ever fix that :-) 13:48
that is to say 13:49
i kind of know how to fix that
but i don't think we should
13:50 FROGGS joined
psch to be fair, the one point where i noticed it being a real issue is with NativeCall, i.e. the test suite tests non-specific int against long, which works on 64bit and fails on 32bit arch 13:50
brrt hmmm
psch but then, interfacing with c code without explicit bit sizes for int is probably a bit not-so-great anyway
brrt ok, i see
hmm, indeed 13:51
i don't actually know how nativecall works, but i kind of imagine it being a pain on 32 bit 13:52
what with the many different ABI's
FROGGS on the other hand you want to make it as easy as possible for the user
13:52 bluescreen10 joined
FROGGS so we need to make that tests pass on 32bit, without modifying the test 13:52
13:53 uniejo joined
brrt hmmm 13:53
moritz do we have all of int, int32, int64 available for nativecall?
brrt i don't know about nativecall :-) 13:54
FROGGS moritz: yes
13:54 kaare_ joined
brrt does explicitly passing int32 make nativecall do the right thing? 13:55
i.e.
FROGGS the test is about unpacking a C struct with a long inside using a class that has an Int attribute
err, int
brrt: yes
brrt hmmm
FROGGS only on 32bit of course
brrt hhow... wait,
is long 32 bit on 32 bit platforms?
13:55 thou joined
FROGGS for all to read: github.com/jnthn/zavolaj/issues/37 13:56
brrt: yes, according to Perl -V
brrt o
FROGGS ö
brrt hmm 13:57
i suppose that treating int as int32 depending on platform is correct
FROGGS yes, but trying to do it that way makes it explode 13:59
so, I guess I did something stupid or missed something
that is from my ubuntu 14.04 x86 VM: intsize=4, longsize=4, ptrsize=4, doublesize=8, byteorder=12345678 14:01

hoelzro: When I want to do stuff at compose time I just replace ClassHOW with something that has a method compose($obj { ...checks/stuff... callsame(); post-compose stuff } 15:12
With that subclassing ClassHOW of course.
hoelzro jnthn: right, but then users of my library would have to use that ClassHOW that I've built 15:13

rl6-roast-data: 48aec67 | coke++ | / (5 files):
today (automated commit)
jnthn And...the other way they have to use the RoleHOW you built?
hoelzro jnthn: this is what I have in mind: gist.github.com/hoelzro/d552753137568ac5285c
well, apps consume the App::Subcommander role
so I have control over the latter
so I figured I could detect with a custom RoleHOW when the role is composed into a class 15:14
[Coke] rakudo moar tested clean today; jvm & parrot still have one failing test file.
hoelzro unfortunately, that happens too early for my checking code to make any sense
jnthn Oh.
hoelzro if you need more explanation, I'm happy to give it =) 15:15
15:15 uniejo left
hoelzro I would just like duplicate subcommands to be detected at compile time 15:15
jnthn I think I see the problem; need to look at the code to think of a solution...
(the metamodel code
hoelzro ah ha
jnthn )
hoelzro I spent a bit of time looking at it yesterday; I'm sure you'll be able to come up with something 15:16
I think that I may just have to use a ClassHOW and have users subclass App::Subcommander
jnthn Yeah. Not least 'cus I can extend the thing if it isn't up to your use case :P
hoelzro rather than make it a role
jnthn anyway, back to hotel & 15:17

Kirkkaf Hello, can someone provide some guidance on whether I should begin my journey with Perl 5 or 6? I am require to learn Perl to further my career but have never really done any serious programming. 23:05
japhb_ Kirkkaf, What do you mean when you say you are required "to learn Perl to further my career"? Are you working in a group that does a lot of Perl already? If so, you probably want to learn the same one they are using, which is most likely a Perl 5. 23:09
If you were just told "Learn a Perl, it's good for your brain", then your choice is more open. We tend to believe Perl 6 is pretty good for your brain, but it is not bulletproof, hardened, and ready for large-scale high-volume deployments yet. (We are still working on a few final features, as well as heavily working on optimization, bug squashing, and shaving off the sharp bits of edge cases.) 23:11
nickf_mt So, quick question... Looking to get started playing with Perl 6... I note the perl6 book on github was last updated in 2012... Would this still be a useful resource to start with, or should I look at more current online tutorials/refs? 23:13
23:13 atroxaper joined 23:14 BenGoldberg joined
Kirkkaf japhb_, my company is writing alot of Perl but the version was not specified so I guess I will have to get the details but are the two very different in design? 23:17
23:17 atroxaper left
japhb_ Kirkkaf, Yes, Perl 6 is a completely new language, more of a sister language than a version increment. 23:17
Perl 6 includes a large number of features that couldn't reasonably be retrofitted into Perl 5 due to backwards-compatibility constraints in the Perl 5 community. 23:19
So Perl 6 takes advantage of the compatibility break to include some amazing new features.
23:21 dmol left
japhb_ nickf_mt, What kinds of things are you interested in learning? 23:21
23:21 FROGGS left
japhb_ Note that I've not read the GitHub Perl 6 book, as I joined the community before it was written. 23:22
nickf_mt hrm... didn't have a lot of specifics in mind, just looking to play with a new language. I guess I'll probably be wanting to interface with databases, use regex if I use it at work down the line 23:25
maybe output excel files. (working through the cpa exam atm, starting as a tax accountant in september)
23:27 gfldex left
nickf_mt Any idea how much the language itself has changed in the last 2 years? As opposed to ironing out implementation/performance issues 23:29
japhb_ nickf_mt, You'll definitely want to learn about Grammars. jnthn++ has a good talk on this: jnthn.net/papers/2014-fosdem-perl6-today.pdf 23:33
23:34 Kirkkaf left
nickf_mt excellent, thank you. downloading :) 23:34
japhb_ As for language changes, there have been changes in the concurrency design, an expansion of Rakudo to multiple backends that had some knock-on effects as we learned more, a fleshing out (and implementation) of the more advanced module ecosystem design, and so on. 23:35
The core language hasn't changed much, just gotten smoother, less buggy, faster, and so on. 23:36
Oh, there have also been improvements in I/O, especially with the creation of the async I/O model.
(I'm sure there are more that I am forgetting off the top of my head.)
nickf_mt ok... so sounds like I should plan on looking elsewhere once I get past the very basics, unless they update that book :) 23:38
given my large block of freetime to really dig in will be August though, I shan't count on that happening 23:39
Oh, sounds like the rest of the family's home. Thanks for the info, japhb . See y'all next time I have a little downtime! 23:41
japhb_ nickf_mt, The channel is quite helpful too, and most active from about 8 AM to midnight in the European timezones (others are available in Asia and Americas, but fewer of us at any given time).
