hi snarkyboojum
I just saw your msg
snarkyboojum ingy: hi ho
ingy snarkyboojum: I've been refactoring quite a bit 00:26
I'll push in a sec for a code review :)
I actually have a few q's
snarkyboojum ingy: lovely - just a few things that stood out for me on a quick read
00:28 rv2733 joined
ingy snarkyboojum: pushed. the code is now very different. uses multi methods. still lots of duplication 00:34
snarkyboojum: you might want to ufo make install testml-pm6, to run the yaml-pm6 `make test` suite 00:35
snarkyboojum ingy: cool - will have a play :)
ingy snarkyboojum: for extra credit I have two tests at the bottom that are almost passing. just some extra whitespace. remove the --- SKIP lines to enable them 00:37
snarkyboojum: also let me know if you want a commit bit.
snarkyboojum ingy: cool! will do

snarkyboojum ingy: weird symlinking issues in t/ for testml-pm6 seem to prevent tests from finding *.tml files 00:48
ingy sorear: ah, yes 00:50
grab testml-tml from github
snarkyboojum ingy: i.e. testml-tml -> ../../testml-tml from the t/ directory - assumes I have the testml-tml repo checked out at the same level as testml-pm6 repo 00:51
ingy and just clone it next to testml-pm6
snarkyboojum: I have 3 implementations using this testml-tml suite.
soon to be a dozen
submodules could work too. 00:52
s/sorear:/snarkyboojum:/
I assume a make dist would tar up all the files for a typical module installer 00:53
anyway, hopefully not a big deal 00:54
snarkyboojum: also grab the latest ufo and do: cd testml-pm6; ufo - | make -f - install clean 00:55
to install testml for running yaml tests
snarkyboojum: also I fixed one of the whitespace bugs
will check that in now. 00:56

ingy today was a good p6 day. thus breaking my record losing streak! 01:35

tylercurtis Good afternoon, pmichaud. 01:38
pmichaud this is why we need Rakudo Star and more people writing programs/modules for Rakudo :-)
to find the bugs that we can fix :)
ingy pmichaud: yes, it was a banner field test day
pmichaud: now with testml and yaml, I can start producing lots more mods
pmichaud rakudo: say True..2; 01:39

01:46 snarkyboojum left
tylercurtis pmichaud: how can I convert a PAST::Op(:pasttype<call>) with the sub in the name into a PAST::Op(:pirop<tailcall>) node? 01:46
pmichaud I think: 01:48
PAST::Op.new( :pirop<tailcall>, $old.name, |($old.list))
anyway, the steps to do: 01:49
1. change :pasttype to 'pirop'
2. change :pirop to 'tailcall'
3. unshift the sub name to be the first child
that probably works.
if it doesn't like the sub name as child zero, then change that to do a 'find_sub_not_null' pirop 01:50
tylercurtis Thanks. I'll try that. 01:52

moritz_ the example graphs from scruffy.rubyforge.org/ are all gone :( 13:25
I wanted to motivate people to port scruffy to Perl 6
but I think they will be far less impressed if there are no shiny graphs to show 13:26
and in the bug tracker there is a report about it from 2009-09 13:27
mathw :( 13:29
moritz_ maybe I should really port Chart::Clicker instead
colomon what happened in the p6 packaging world while I was out? is pls working? 13:30
moritz_ don't think so
bbkr is this ticket still valid? rt.perl.org/rt3/Ticket/Display.html?id=62002 looks like it was created before Mu object was added to spec.
mathw colomon: you might want to go out for a bit longer :)
moritz_ bbkr: well, it's now s:g/Object/Mu/ 13:31
bbkr: but all in all we still need a good default .perl method
pmurias moritz_: why are the example graphs all white
moritz_ pmurias: because they've fucked it up. And I can't find anybody who could fix it 13:32
pmurias: and I'm kinda disappointed, because when I decided to port that lib to Perl 6 (back in 2009 I guess) it was all pretty, and a good incentive
jnthn Port it and then be like "and unlike Ruby we can show you thre pretty!" ;-) 13:33
moritz_ jnthn: problem is, I don't want to port it all by myself
jnthn Ah :-) 13:34
bbkr moritz_: thanks. but since both code samples work then the main problem in ticked - .perl method not available in user defined class - is solved (despite output it generates)
ticket*
moritz_ jnthn: so I want to show people "look at these pretty graphs, don't you want to write that for Perl 6 too?"
bbkr: if you say so... then somebody will open a ticket about Any.perl being useless
I don't mind either way

2) use perlbrew to install a perl-5.12.1 in ~mildew/usr/
3) use the new perl to install all the modules, and mildew 14:01
sane?
not sane 14:02
because I need to set PERL5LIB for perlbrew to find its module
which will likely confuse further installations 14:03
better ideas? install perlbrew on the system?

pmurias keep it mind that i first used it today so i'm no expert on it 14:06

16:53 silug joined
moritz_ right 16:54
TimToady it's really a circularity saw issue; do primitives that invoke .defined internaally have $! handling semantics, or should there be a lower-level .__defined__ -ish thing
jnthn TimToady: Aye, I didn't expect to fix that. 16:55
TimToady do you know how it's happening?
jnthn TimToady: I was just fixing the re-catch.
TimToady is there a deep .defined somewhere? 16:56
jnthn Well, at the moment it appears to always mark an exception as handled.
Whatever happened inside the CATCH
TimToady: Sorta in the sense that there's the Parrot v-table interface 16:57
16:57 cjk101010 left
TimToady but it should have redied when it hit the end 16:57
jnthn Which hs a defined v-table method
TimToady if there's an implicit die at the end that is only bypassed by 'succeed', how did it not die? 16:58
jnthn TimToady: I know - the code we generate at the moment just unconditionally marks the exception as handled though.
isBEKaml when doing CATCH { when * { ... } }; what does * catch here? Are we speaking of catching exceptions in terms of unix-y errnums or Exception classes ?
TimToady should have died again anyway 16:59
16:59 cdarroch joined, cdarroch left, cdarroch joined
jnthn TimToady: huh? 16:59
TimToady isBEKaml: yes
there's an implicit die/rethrow at the end of a CATCH that gets bypassed by a when's 'succeed' breakout
jnthn Right, I know that's how it should work.
That's just not the way it's been implemented. :-( 17:00
So it needs a re-work.
jnthn didn't write any of the original exception-y stuff - yesterday was the first time I hacked on that bit.
tylercurtis It seems like that could be a problem even with non-primitives. After all, if .defined and .Bool mark as handled, then you have to be very careful about what functions you call with $! in a CATCH. 17:01
TimToady isBEKaml: more specifically, 'when' is doing smartmatching, so if you match numerically, you'll get errnos, and if you match type-ly, you get exception classes
and 'when *' always matches anything
it's another way of writing 'default'
ingy what doe .HOW do?
*does
TimToady tylercurtis: yes, that's what I was trying to say re circularity saws 17:02
tylercurtis On the other hand, sometimes you actually do want to defer your exception-handling logic to a separate sub.
moritz_ ingy: it returns the metaclas
cognominal TimToady, what is the status of Whatever for dispatching in the light of Range as a role?
moritz_ HOW = Higher Order Workings
[Coke] that's what the synopses need, an index.
lue ohai o/ 17:03
isBEKaml TimToady: in that case, is there any way to define our own exceptions? Contrived Eg., when dealing with currencies, I don't want to see numbers without decimal points. So can I write code to throw exceptions when format errors liek these crop up?
moritz_ [Coke]: they had one, last I looked
tylercurtis TimToady: right. It sounded like you were mostly concerned about primitives, though.

ingy moritz_: how do I test if a value is undef?
lue well, I originally thought it was a trait :)

moritz_ doesn't really like notdef
ingy is Nil a value? 17:47

ingy is there a scalar value that closely matches undef in p5 or null in js or None in py?
moritz_ pmurias: I don't really know. So far I focused on *not* having persistence, so that executions that screw up something don't affect future evaluations
pmurias the process doing the compilation would be forked from the persitant one 17:49
moritz_ currently the ulimit affects child processes too 17:50
so one thing you could do is having a separate process that's running all the time
to which mildew then connects
if that helps
then it would be outside the resource limits in evalbot

sbp so basically to allow some form of short circuiting to work, do I understand right? 18:20
TimToady unfortunately, p5 borrowed the commutative one before we figgered that out
it's really a reverse dispatch based on the type of the pattern
$a ~~ $b is really $b.ACCEPTS($a)
so $b is totally in control, unless it wants to share with $a 18:21
PerlJam wait ... p5 ~~ is commutative? /me looks

TimToady was, they're recovering from that 18:21
lue are there any other post constraints besides 'where' ?
TimToady yes, signatures
sub foo ($x ($a,$b) ) 18:22
or [$a,$b] equivalently
note, space before is required, or it's a shape declaration on $x
jnthn It's not quite equivalent. :-) 18:26
[ ... ] implies Positional too, iirc
TimToady on CATCH blocks, I'm thinking CATCH { ... } really means CATCH { $!.handled = 1; ...; die $! } where the die "unhandles" $!
STD doesn't care, just parses a sig inside [...] there
jnthn Well, nor does Rakudo at the parsing level ;-) 18:27
TimToady arguably, it could be disallowed to prevent accidentaly use as a shape, but that'll end up with undefined $a error anyway

tylercurtis moritz_: I'm looking at the scruffy tests, and I'm wondering why it is that the default value for Scruffy::Graph.new.theme.class is Scruffy::Themes::Keynote, but then testing setting the theme set it to Scruffy::Themes::Mephisto(which I'd have thought should be the class of the new theme?). 18:42
I suppose it doesn't matter since the test doesn't do anything but test that you can assign new values to @graph.theme, but it looks asymmetric to test that the class of the default .theme is a certain theme class, then set .theme to another theme class to test that it can be set.

ingy why does $.h need to be rw to clear it? but not to add to it? 20:24
arnsholt IIRC object attributes are ro by default 20:25
tylercurtis ingy: because the immutability of the attribute container doesn't make the value immutable.

tylercurtis ingy: $f.h{'x'} = 5; doesn't change what value the container it holds.
jnthn Also because the constructor is "on the inside" and can get at the underlying $!h 20:26
moritz_ ingy: $.h{'...'} = foo just translates to a method call on $.h
whereas $.h = $stuff is assignment, which honors the rw property
