Set by moritz on 22 December 2015.
Kaiepi this isn't so much a perl question, but just a general programming question 00:55
i have a native struct class that has some ucs4 string members hastebin.com/zoxebisalu.rb 00:56
would it be a good idea to have start and end methods in it to convert them to utf8 strings to make it easier to view them?
timotimo hm, if we had ucs4 support in core, you could just define those as Str with "is encoded" 00:57
Kaiepi yeah, problem is there isn't
afaik
timotimo in theory you can write your own; i'm not sure if nativecall would actually use that properly yet
Kaiepi the library i'm writing this for has stringprep_ucs4_to_utf8, which can do it for me 00:59

ZzZombo eh
Can I make that return `NaN` instead?
Zoffix ZzZombo: yes, use Num view 01:48

camelia NaN
Zoffix m: <0/0>+2.0 andthen .say orelse .Num.say

Zoffix So, for rakudo.org, 99% of posts are release announcements. I'm going as far back as 2015/11/28, up to and including "Announce: Rakudo Star Release 2015.11 (now in beta!)" and copying the stuff to new stuff. For earlier release announcements, I'll add rewrites to point to release notes on github. Everything else (there are a couple of ancient posts) I'm leaving behind. 03:36

Kaiepi i love how easy it is to write c/c++ wrappers and how you can give methods and properties the same name so i can do stuff like this hastebin.com/pasokoxiji.rb 04:00
doing this in node this would require several different files and be complex as hell 04:01
and would require a Makefile and compiling on npm install 04:02
i don't have to do any of that in perl

camelia (CArray[Pointer)
Kaiepi shouldn't that be (CArray[Pointer[int32]]) ?
Zoffix yeah 04:22
Zoffix hahahaha 04:35

Kaiepi lol 04:38
that looks like something i might be able to fix
i'll have a go at it 04:39
Zoffix Go for it :)
Kaiepi: note the .nqp extension of the file. It doesn't have full Perl 6 language available there. You can find docs for NQP ops here: github.com/perl6/nqp/blob/master/d...s.markdown 04:40
Kaiepi thanks
Zoffix (and you can test stuff by running `nqp some-file-with-nqp-code.nqp`; will be faster than recompiling entire rakudo each time) 04:41
Kaiepi i'm required to use := in nqp, right? 04:42
Zoffix Right 04:43
And parentheses are required on subroutine calls.

camelia ===SORRY!===
The 'for' op expects a block as its second operand, got QAST::Op
Kaiepi how do i make a block? 04:59

camelia NativeCall::Types::CArray[NativeCall::Types::Pointer[int32]]
Kaiepi is it fine to use regex for nqp stuff? 05:10
Zoffix Kaiepi: yeah, but it might be faster not to 05:12
Kaiepi hm
Zoffix
.oO( recursion )
Kaiepi actually i don't need regex since only the last element of @names will have ] in it at all 05:13
wait, it's possible for a role like Foo[Bar[Int], Bar[Int]] to exist right? 05:15
Zoffix yeah, prolly 05:18
Kaiepi hm this might be tough 05:19
Zoffix m: my Callable[Int] %h{Callable[Int]}; dd %h 05:20
camelia Hash[Callable[Int],Callable[Int]] %h = (my Callable[Int] %{Callable[Int]})
Kaiepi m: role Foo[::T] {}; role Bar[::T1, ::T2] {}; Foo[Bar[Foo[Int], Foo[Int]].new 05:22

camelia Foo[Bar[Foo[Int],Foo[Int]]].new
Zoffix Kaiepi: but feel free to use a regex. $non-buggy > $performance 05:36
And likely isn't a method that's called very often
Kaiepi i still need to test, but i might've worked out a way to do it without regex 05:37
Zoffix cool 05:38
m: role Foo::Bar::Ber[\T] {}; my Foo::Bar::Ber[Foo::Bar::Ber[int32]] %h{Foo::Bar::Ber[int32]}; use Test; is-deeply %h.^shortname, 'Hash[Ber[Ber[int32]],Ber[int32]]' 05:41
camelia not ok 1 -
# Failed test at <tmp> line 1
# expected: "Hash[Ber[Ber[int32]],Ber[int32]]"
# got: "Hash[Ber"
Zoffix (prolly a test that can cover the bug)
Kaiepi never mind, i'll need a regex for this 05:46
i'll get something working tomorrow 05:47
Zoffix don't look like you need a regex for that one tho 06:39
Zoffix nqp: gist.github.com/zoffixznet/da3b0ce...f8483b2f05 06:41
camelia CArray[int32]
CArray[Pointer[int32]]
Hash[Ber[Ber[int32]],Ber[int32]]
Zoffix .tell Kaiepi not 100% sure, but this seems to do the trick, without regexes: gist.github.com/zoffixznet/da3b0ce...f8483b2f05 06:42

rashadulxslam hi, can someone please help me with example and link "how to create a pidgin plugin which will take unix command as input and sendIM as output to the user" 12:43
moritz rashadulxslam: is this some kind of homework assignment? 12:51
rashadulxslam moritz: yes 12:55
El_Che rashadulxslam: have a look at libpurple 12:56
rashadulxslam El_Che: already working on libpurple but hard to get such example
El_Che that's why homework is fun 12:59
Work from there: developer.pidgin.im/wiki/Scripting...%20Plugins
and have a look at the source of simple plugins here: developer.pidgin.im/wiki/ThirdPartyPlugins
rashadulxslam El_Che: yes already working on those plugins - need some simple example :) 13:04
which i mentioned in my question
moritz nobody is going to do your homework for you 13:07
rashadulxslam moritz: thats why asking for some reading notes and perhaps some great examples 13:08
tadzik well, you may have more luck asking on some pidgin-related channel 13:09
rashadulxslam tadzik: let me copy the question before make a mark leaving the channel - thank you moritz and El_Che 13:13

El_Che rashadulxslam may not get his degree but he has a bruight future at Google... searching 13:17

dylanwh mst: I know the alternative for Taint::Util but I need that path to be very fast. :) 16:32
mst my general solution to that sort of problem is to introduce a validation barrier and defenestrate taint mode 16:33
I'm aware that's probably not a practical option for you, mind
dylanwh I'm keen to reove it, but that will wait 'til after I have a usable 6.0 release 16:39

Pilu how can I fill in a shell prompt from a script? 18:31
AlexDaniel Pilu: perhaps you should just pass something to stdin of the program you're trying to run? Do you have any code already? 18:34
timotimo by prompt do you mean the symbols it puts in front of your cursor?
like path, username, and a $ or # or > or something?
Pilu I want to push a repository using git 19:11
it asks me for username and password
El_Che Pilu: use ssh or have a look at git config 19:12
Pilu so it can't be done with perl? 19:13
El_Che shure it can, but it's a reinventing the wheel kind of thing 19:14
what sometimes do in code is create GIT_ASKPASS programmatically and go from there 19:15
git-scm.com/docs/gitcredentials
(on repos that don't use ssh keys)
Pilu I am curious how to do this in perl
can you tell me what to read 19:16
or what to search on google?
El_Che have a look at the link I pasted. A simple algorythm would be:
create a file (script) that outputs the password, like "echo -n password" 19:17
set the env variable GIT_ASKPASS that points to that file
that's it
mspo dylanwh: reduce them 19:25
mspo dylanwh: I just wanted to use it; don't mean to offend 19:34
dylanwh I'm not offended. I just got involved this 4 years ago. No-XS isn't a requirement for me. But I'd accept PRs to that. 20:16
El_Che dylanwh: maybe I am naive, but doens't XS speed things up? it's a big app 20:17
dylanwh XS is vital for bugzilla.mozilla.org. 20:19
dylanwh before I started using untaint() from Taint::Util, we had 6 million calls to the regexp /^(.*)$/ 20:19
El_Che wow 20:20
dylanwh also Cache::Memcached is worse than using no memcached.
mspo those all sound like bugs :)
moritz can you please keep the bugzilla discussion out of #perl6?
dylanwh Sorry. :)
timotimo surely /^(.*)$/ is optimized out the wazzoo in perl5? 20:33
dylanwh it's not faster than just unsetting the taint bit 20:36
dylanwh but I won't speak further here. I have my own irc channel. :) 20:36
timotimo right, but it could compile down to just an assignment to $/ and the untaint?
mst I think the regexp questions can go to #perl 20:38
and there's a #bugzilla on irc.mozilla.org for bugz stuff 20:39
(I am in that one too)
dylanwh mst is everywhere. 20:40
El_Che mst is a concept 20:41
a state of being
