brrt good to know
moritz, your site is back online :-) 07:16
moritz brrt: I noticed :-)
brrt i didn't, until now :-)
yay
moritz and ilbot6 has been logging for two days now without interruption (though only into a test database)
FROGGS Heather: so you suggest that panda should install its dependencies via git? 07:17
moritz seems to work with both postgres and mysql
Heather FROGGS well it does it by default...
FROGGS but it's using some packages for bootstrap itself, I suggest to use them as submodules 07:18
FROGGS Heather: how can panda work if its deps are missing on a clean system?
brrt nice
Heather FROGGS what do you mean? 07:19
FROGGS why will they be missing?
07:20 berekuk joined 07:21 census joined 07:22 berekuk left
FROGGS Heather: if you install rakudo and then clone panda, then it has no deps, and it cant install them because it doesnt know how to parse the META.info of a module that should be installed 07:26
Heather FROGGS it has deps as submodules :) 07:27

Heather FROGGS here is good example of submodules usage github.com/mozilla/servo/tree/master/src 07:27

FROGGS Heather: so when cloning the repo these get automatically cloned too? 07:28
Heather FROGGS with --recursive
FROGGS or after clone you do git submodule init & git submodule update 07:29
FROGGS I see
Heather FROGGS there is possible trick to add init & update to bootstrap

Heather bonsaikitten mono is using submodule init & update on configure 07:34
bonsaikitten *twitch* 07:35
BAD
that means the downloaded stuff is not stable and might randomly change, which breaks all kind of ass-umptions about packaging software 07:36
Heather bonsaikitten source is not package... 07:37
bonsaikitten they don't expect someone want to install stuff by automate source compilation
bonsaikitten Heather: try building stuff that randomly auto-updates
you can't reproduce your results -> invalid
Heather bonsaikitten it's easier to develop with such structure 07:38
07:38 skids_ left
Heather bonsaikitten by the way you must know that submodules DOES NOT AUTO UPDATES 07:38
bonsaikitten no, it's not

bonsaikitten people hacking build systems on MacOS are not good for my mood
Heather bonsaikitten eh? do you use macos? 07:46
brrt MacOS (X) isn't at all good for my mood
bonsaikitten Heather: no, but people hacking up random stuff do 07:47
and then I get to decipher what they intended the build system to do
just because it accidentally works on macos doesn't mean much
Heather yes I usually hate when people use a lot of posix stuff, it's hard for me to use it on windows :( 07:48
bonsaikitten for me the problem is "why are you calling ar directly ??!? lern2ld"

arnsholt Heather: My work computer has Red Hat Enterprise Linux =) 07:51
But at least they've managed to upgrade Perl to 5.10 in the one we have now
Heather arnsholt I'm fine with rhel ) I like rhel, I'm not banned on #rhel and rhel enterprise support are mannered and friednly 07:52
arnsholt there is epel...
labster I'm not so hating the Mac OS X as annoyed that it's randomly not working after running about 15 minutes on one of my machines. Any time `ls /` produces no output, you know you got a problem.
bonsaikitten CentOS is a funny game
arnsholt I don't have privileges to install packages on my own machine =( 07:53
labster Hi Heather o/
brrt oh, that hurts
bonsaikitten arnsholt: that's sad
arnsholt (At work)
Heather labster hi
brrt can you install into a 'local' directory?
bonsaikitten luckily I am root
arnsholt Yeah. So my $HOME is slowly accreting stuff I need/want
labster glad to see you around again.
bonsaikitten it's a lot easier that way :)
brrt arnsholt, i do that on all computers
much easier in installation / uninstallation
Heather brrt I doubt 07:54
arnsholt But sometimes the old^Wmature versions RHEL ship are impractical beacuse they're not always compatible with the versions I get on my laptop (which has Ubuntu)
Heather brrt I have no user instead of root on most of my machines
brrt hmm 07:55
Heather dinner time
arnsholt Just yesterday it turns out I can't compile the Haskell code I wrote at work on my laptop, because they've changed the module layout between GHC 7.0.4 and whatever version Ubuntu has
brrt thats not really either ubuntu's or fedora's fault
arnsholt Well, my annoyance is that the RH packages are a bit too old for my tastes 07:56
Perl 5.10 for example is about 4 years old

arnsholt It's a wrapper around dmenu: dmwit.com/yeganesh/ 08:20

arnsholt (For the Java calling stuff)
lizmat would it make sense to generalise this to VMCall, or are the VM's too different for this? 10:41

Ulti that leads to karma inflation

Ulti wow we solved it economies just need negative currency
pmurias lizmat: re generalising to VMCall, a large part of NativeCall is specifing the signature of the functions and a lot of that will be made unnessary when calling Java code etc. 10:51
lizmat because that can be introspected automatically, is what you're saying ?
pmurias yes 10:52
jnthn pmurias: Oh, I interpreted the question as "what if we have .Net support some day and want to call that stuff" :)

eiro right ... but it seems nicer.
pmurias if the reflection happens once at starup/compile time it shouldn't be much slower than parsing programmer specified signatures
arnsholt My current plan was to do what had to be done on the C level with dyncall/JNI more or less like on Parrot, but this is potentially a lot cleaner 10:56
10:56 Heather left
jnthn arnsholt: I think the key thing is to get the NativeCall module API consistent. What's inside of NativeCall can happily vary. 10:57
arnsholt Definitely
The only way to do this on several platforms and escape with my sanity intact is to expose a consistent nqp::op API on all the platforms 10:58
jnthn Yeah. Whether the current one is sane is the question :) 10:59
arnsholt That's definitely open for discussion
But if we're comparing sanity, I'm more anxious to twiddle the Perl 6 API than the NQP API, to be honest
donaldh arnsholt: yeah, JNA + JNAerator = awesome.
arnsholt Oooh, neat 11:00

FROGGS I thought there is a text like "you can add commits to this pull request by pushing to the branch XYZ" here: github.com/rakudo/rakudo/pull/138 11:40
maybe just you will see it 11:41
lizmat but I wanted a commit *not* to be part of that pull request 11:44
fortunately, masak already committed the necessary change
FROGGS yeah, so you have to commit to another branch
lizmat clear 11:45

What if several modules import the same module? 16:01
TimToady thing is, if these phasers only run once, then you can't depend on the order anyway 16:02
arnsholt Yup
PerlJam It works for Perl 5 ;)
TimToady well, Perl 5 one-ups Perl 6 by distinguishing CHECK from UNITCHECK. currently we confuse those concepts, I think 16:03
16:04 domidumont left
TimToady maybe they should be called CHECK and DOUBLECHECK :) 16:09
masak gtodd: I'm having second thoughts about the ONELINER exercise -- github.com/masak/workshop/issues/19 -- I think there's something in there can be done better.
16:09 census left
PerlJam DOUBLECHECK is too long, how about RECHECK? 16:10
TimToady well, or use a different word entirely
masak CONTROL :P
TimToady app-level check is when we start making big assumptions about what can be optimized
POPQUIZ and FINAL :) 16:12
FINAL would be when you finalize your classes... 16:13
PerlJam FINAL has some nice appeal to it
(I actually thought we already had a phaser called FINAL though) 16:14
TimToady a bit of confusion with what other languages mean by "final", but maybe that's okay
16:15 SmokeMachine joined
gtodd masak: the issue identifies a valid problem for oneliners ... move the expansions to a new node/excercise and call it ... errm maintenableness or something 16:16
16:16 pmurias left, kivutar left
gtodd masak: of course putting the oneliner in a shell script and adding comments trying to explain what it does would be cheating :) 16:16
TimToady the other minor problem is the confusion of changing UNITCHECK/CHECK to CHECK/FINAL, but we're already pretty heavily confused in that area... 16:17
PerlJam maybe do something similar to "DOC INIT" and have "UNIT INIT" and "UNIT END" instead? (doesn't help with FINAL though) 16:19
those at least would be a little more self documenting 16:20
16:21 kaleem joined
TimToady and we never did define a COMPOSE phaser for roles... 16:21
is that still desirable? 16:22
PerlJam I think so.
masak gtodd: well, the purpose of the exercise was to send a message like "ooh, look how oneliners and full-fledged scripts are simply different modes of expression, suitable in different situations". but I suspect there is a more effective way to convey that.
TimToady: yes, I think so.
TimToady what about a DECOMPOSE phaser? :D 16:23

distinguish FINAL phase from CHECK phase

CHECK phase is always after the parsing of the current compilation unit. FINAL phase is after the main application's CHECK phase, when the application as a whole commits to optimization policies. In other words, a FINAL block defined in a module is not run when the module is compiled (that would be a CHECK instead), but rather when the application using the module is completing its compilation and linking.		 17:32

lizmat jnthn: while trying to grok load_module (Perl6/ModuleLoader.nqp), I found that "locate_candidates" is doing *4* stat()s for each file on each %INC dir 19:04
when in the case of .pm6, you would only need 1 stat(), and in the case of .pm only 2. 19:05
also I think there is a bug there: if in one %INC dir a .pm6 file has been seen, it will never check for .pm files anymore 19:07
19:07 berekuk joined
lizmat hmmm… 3 in case of a .pm file, 2 in case of a .pm6 file 19:09
FROGGS lizmat: well, atm it prefers .pm6-files, yeah 19:10
lizmat yeah, that's fine
FROGGS later it has to choose the best one (highest version) that fits our search criteria
PerlJam It's too bad there isn't some sort of single file index it could look at. 19:11
lizmat it's just that suppose we search for a A in ./a and ./b, if it has seen a ./a/A.pm6, it will not check ./b/A.pm6 for existence
FROGGS: so you're saying this is intentional?
FROGGS yes 19:12
lizmat: what should it do when it finds more than one candidate? it cant tell which one is better
lizmat well, locate_candidates appears not to short-circuit when it finds one 19:13
FROGGS but load_module always will use @candidate[0]
lizmat indeed… isn't that silly though? that's a *lot* of unneeded stat()s then 19:14

lizmat wrt load_module: it appears that it is searching all @INC directories even if the module already has been loaded 19:30
FROGGS hmmm, that is not very clever 19:31
lizmat it needs to do that because locate_candidates generates hashes with the fully qualified filename 19:32
and that's what load_module uses as a key for %modules_loaded
FROGGS hmmm, can't it use the module-name? 19:33
lizmat I guess it could, but it doesn't
FROGGS well, I guess it takes a while till we have full S11 support, so maybe it makes sense to optimize it a bit 19:34
or maybe this time should better be invested for S11 research :/ 19:35
lizmat well, looking at ModuleLoader.nqp, I think I can make an alternate version that would live next to this one 19:37

lizmat wouldn't a Stringy.pm type approach work?
jnthn FROGGS: I didn't think Perl 5 had any methods on stuff like strings?
lizmat STDERR->print ? 21:17
FROGGS STDERR is not a string
jnthn: it has no methods, but it does things like .Numeric if prefixed with - 21:18

FROGGS lizmat: not sure if Stringy.pm would do the trick, but I guess not 21:19
lizmat I was just proposing an idea, no idea whether it can work or not 21:21
colomon lizmat: what do you mean by a Stringy.pm type approach? 21:24
21:25 araujo joined, araujo left, araujo joined
lizmat my class Str does Stringy 21:25
to prevent code duplication
FROGGS the problem is, class Str does a lot of work (some parts I need to change though) 21:26
21:26 dmol left
FROGGS and in the AST, there is a callmethod Stringy, which I suppose is Mu.Stringy, which calls self.Str 21:26
colomon ah. I think that's a bit backwards ... at least, I'd expect things like conversion to Int to be implemented in Stringy, not Str. And that means you'd get the p6 behavior. 21:27
and miss functionality you need.
FROGGS so I am currently trying to supply my own Str class which overrides the current in the given scope
colomon: looks like this conversion is living in Str
colomon FROGGS: that's probably a "bug", though. 21:28
FROGGS Representation must be composed before it can be allocate
-.-
colomon at least, I would certainly expect other Stringy classes to handle things like conversion to Int the same way Str does. 21:29
I'd think your P5Str mixin role is a solid idea.
Or a P5Str class which is implemented in terms of standard Str.
FROGGS there is no other class that does role Stringy 21:30
lizmat but there must have been a reason to do it like this?
FROGGS but I cant replace an existing method by mixing in my role?
role Stringy is empty, but its file has defines infixes... 21:31

masak even tadzik's "decomposing" today ultimately relies on the ability of English to muddle transitive/intransitive. 21:36
colomon FROGGS: and what you'd expect with that is a type which is pretty much just like Str, except its storage representation is different.
