 08:33
moritz just added the 100ths module to that list
tadzik \o 08:35
time to run smoketests
moritz note that DBIish currently needs a branch of both nqp and zavolaj
tadzik ach
arnsholt But I suppose we could merge that branch 08:36
moritz ie test failures with an out-of-the-box rakudo are to be expected
arnsholt: please do
08:36 cosimo joined
arnsholt First of all, I was holding off for a bit of independent verification that my code wasn't broken in some obvious way 08:36
tadzik moritz: do DBIish tests rely on DBDish backends?
moritz tadzik: yes 08:37
tadzik ack
we do need some cool mechanism for those
moritz tadzik: over time I want to make them more robust, so that unavailable dbs simply skip their tests
tadzik would be cool, yes 08:38
arnsholt I suppose we could at least provide a mechanism via the dyncall ops to try to load a lib and die if loading fails 08:41
jnthn suggests adding an extra op 08:43
And then a sub in NativeCall
arnsholt Yeah, that's what I was thinking too 08:45
08:45 scott____ joined, dakkar joined
arnsholt I just have to figure out how to add an op to nqp_dyncall.ops 08:45
08:46 SatoAmbush joined
arnsholt (I'd like to add a write-barrier op as well, to handle creepy action at a distance changes to C storage) 08:46
08:46 scott___ left
jnthn arnsholt: Edit the .ops file, inline op nqp_dyncall_can_load(out INT, in STR) { ... } 08:46
Something like that. 08:47
arnsholt Yeah, that looks familiar
08:47 dakkar_ joined 08:48 dakkar left, dakkar_ is now known as dakkar
moritz fwiw I don't even know if I need such an up 08:49
*op
I'll just do try { DBIish.connect(...); CATCH { skip "No DB connection: $!" , $number; exit }} 08:50
jnthn I suspect it's useful for implemetning the .bundle vs .dylib stuff, and good to have for other bits.
moritz yes, agreed
arnsholt Yeah, there's that as well
moritz just sayin' I'm not blocking on it
tadzik duh, panda suffers the same problem as URI, non-deterministic precompilation :/ 08:51

jaffa4 hi
How do you debug perl 6 programs?
tadzik with say(), usually :)
09:06 _-`user0_ left
tadzik and Grammar::Tracer for grammars 09:06
jaffa4 that is so archaic.
tadzik yes 09:07
moritz jnthn: you are welcome to contribute a proper debugger
erm, meant jaffa4
though jnthn is of course welcome too :-)
jaffa4 jnthn: please write us a debugger
moritz jaffa4: please write us a debugger 09:08
jaffa4 Is there support for tracing, brackpoints? 09:11
brack=> brakepoint
breakpoints
arnsholt There might be a Parrot-level debugger, but nothing on the Perl 6 level for Rakudo AFAIK 09:12
jaffa4 WHat about niecza?
arnsholt Dunno. Never used it 09:13
Probably some kind of Mono debugger at least
jaffa4 I guess then some kind of debugging should be inserted into generated bytecode 09:14

estrai is there a way to open/readir in rakudo? 12:52
moritz estrai: dir() lists all entries of a directory
masak IE 9.0.8112.16421 here. 12:53
moritz estrai: lazy lists make explicit iteration over directories unnecessary
masak is tired, but less so than yesterday 12:55
estrai moritz: thanks, that worked, is there a way to use it with a glob?
masak moritz: that's actually a really good example of how lazy lists have emergen changes on the language.
moritz estrai: no
estrai: but you can grep with regexes 12:56
dir('.').grep: / \.txt $ /
masak wouldn't mind a module providing XPath-like search capabilities for dirs and files
jaffa4 Is it true that one can one use regular expressions on files directly?
tadzik well volunteered! :)
masak tadzik: there's a weekend coming up... :) 12:57
moritz masak: no, not before you've blogged about t4 :-)
estrai moritz: how efficient is that, will it read all contents first and then apply the regexp or is it smarter then that?
masak moritz: +1
moritz: I promise.
moritz estrai: it reads them all (at least if you consume all elements of the result list). But glob needs to do that too.
masak jaffa4: on what, the file contents, the file name, or the file's last-modified timestamp? :) 12:58
jaffa4 on file contents
moritz I'm pretty sure you can't regex file contents without reading them in some way
or at least mmap them
jaffa4 I mean regex on file handle or stream

rurban I've got some packaging questions 13:47
moritz rurban: shoot 13:48
13:48 pernatiy joined
rurban parrot-4.0.3 generated a parrot-nqp (no nqp). rakudo perl Configure needs --with-nqp=/usr/bin/parrot-nqp 13:49
but then the Configure step generated a new nqp and copies it to /usr/bin
is this the same nqp as parrot's?
moritz no.
rakudo needs the nqp from github.com/perl6/nqp 13:50
rurban It should be forbidden for Configure to copy into prefix
13:50 lichtkind joined
moritz uhm, does it? 13:50
it only does for me if you use some --gen-<mumble> options
rurban I see. So --with-nqp=/usr/bin/parrot-nqp is wrong?
moritz which packagers shouldn't use 13:51
rurban It worked for me without the gen steps
moritz rurban: yes, it's worng
lichtkind eny git experts here, git say me that i have untracked files but there are none really
phenny lichtkind: 02 May 16:14Z <masak> tell lichtkind re github.com/perl6/tablets/blob/2c73...y.txt#L197 -- I believe you meant s/terms and statements/terms and operators/

masak I know. :)
tadzik rurban: you may need more than 2GB if you're on 64-bit
rurban Because just yestreday I posted my perl5 perlcc out of memory results to blogs.perl.org 13:53

masak lichtkind: I'm right? great!
moritz lichtkind: 'git' itself doesn't say that. A subcommand of git does. Which one?
lichtkind masak: i mean the phenny msg

last was 2011.07

94 is a TODO 14:20
I have to do the same with perl5
And all the copies of cygparrot-4.3.0.dll do not help with rebase problkems at all. makes it worse. better have only one in /usr/bin/ 14:23

rurban yes, rebased the perl6 dll's and fork tests pass now. conflict was with dynext/perl6_ops.dll and cygiconv-2.dll 14:51
I'm not sure how to codify these steps, as normally you need a dash session without any service and bash running
moritz oh, "fun" 14:52
rurban if the rebase database is already initialized with cygparrot also, then it is only: ls dynext/*.dll nqp/dynext/*.dll > dll.lst; rebaseall -T dll.lst 14:53

PerlJam Should nom ultimiately only have nqp::mumble ops? (i.e., the pir::mumble will have been extirpated) 15:10

PerlJam: but some of the code is very parrot specific, and replacing pir:: by nqp:: doesn't help much 15:11
PerlJam moritz: for instance?
15:11 wtw left
moritz PerlJam: exception handling. Backtraces. 15:12
PerlJam The reason I ask is because I noticed that there are several pir::mumble ops being used that have corresponding nqp::mumble (pir::split, pir::join, pir::chr, etc) 15:13
moritz those could and should be replaced by their nqp:: counterparts

PerlJam Could someone remind what the letters after __ mean in pir::substr__SSI and pir::substr__SSi ? (or where to find out that info?)
moritz type signatures
the first letter is for the returned value
and upper case means it needs to be a register 15:21
PerlJam ok
moritz lower case means it can also be a constant/literal
benabik Type signatures and they're not well documented to my regular irritation. I should just comment them. 15:22
moritz they are documentated somehwere in PCT
benabik Oh.
moritz src/PAST/Compiler.pir 15:23
PerlJam so, the map for nqp::substr says maphash['substr'] = 'substr__Ssii' How does substr__SSI map to that? Is another nqp::substr variant needed?

felher moritz: i thought about typed exceptions for IO and i noticed that we have exceptions as we have function Copy,Mkdir but nothing like a FileNotFoundException. Do we prefer one function <-> one exception? What do you think about mixing? Something like: gist.github.com/2587005 ? 17:17
moritz: the latter isn't a patch-request. It's just some thinking. 17:18
also, the example is kinda stupid, because copy ("valid-file", "non-existent-directory/file") also stringifies like "no such file or directory" :) 17:21
moritz felher: I think we should rather have a big enum with IO errors 17:22
felher: and then an X::IO::Copy exception could have an $.os-error which could be X::IOTypes::FIileNotFound 17:23
masak an enum would make it non-extensible.
moritz right 17:24
even if we don't do with enums, I think it should that the actual IO error should be inside the error from the operation 17:25
because "copying failed" is more high level than "file not found"
felher agreed :) 17:26

moritz jaffa4: it's not valid syntax

moritz well no. .say is a method call, say $_ is a sub call 18:23
They happen to do the same thing in this case, but the distinction is important

masak right. subs != methods 18:28
you can use one as the other, if you really want to.
but they are different. they occupy different namespaces. only methods have a notion of an invocant. 18:29

rurban rakudo star tests do not work unless you install it first. 18:34
This should be documented
masak agreed. 18:36
rurban Or pass all module/*/lib paths to PERL6LIB 18:38
But this gets big
masak generally, one should be able to do 'make test' before 'make install'. that feels like one of those "ambient assumptions", somehow. 18:40
jnthn suspects it may not be the way it currently is on purpose 18:41
May be fallout of the removing of lib from the default path, for example.
masak oh! yes.

tadzik phenny: tell sisar which Rakudo is that? I don't get any warnings in Panda, with or without line numbers
phenny tadzik: I'll pass that on when sisar is around.
moritz jnthn: it supports placeholders, just not in the syntax that perl people expect 20:06

_sri wouldn't an mruby-ish implementation of perl6 make sense? github.com/mruby/mruby 23:50
a reasonably fast subset with just enough features to get started writing real applications and port modules 23:52
flussence nqp sort of does that already, but it's not fast and a bit too much of a subset imo 23:53
(though the speed thing may be the fault of what it's running on, I dunno)

flussence I agree though, a perl6 with most of the standard library stripped away might be useful. Not everyone needs Str.indent after all 23:54
