sorear A language like C++, because of its weak metamodel, only allows a single class per method, and thus a method can appear at most once in a dispatch list and (__function__, typeid(*this)) uniquely identifies the "next" method 00:02
Perl 6 doesn't have that, so it seems like I'd have to allocate storage for the nextsame iterator on every method call

mfollett Not that it really matters, but out of curiosity why is '.?' and such an operator instead of '.' being an operator and '?' being a metaoperator that operates on '.'? 00:40

mfollett Has try.rakudo.org always had the chapters? 01:55
02:01 Eevee joined 02:09 meppl joined
dukeleto mfollett: probably for performance reasons, concerning .? 02:11
sorear mfollett: because . isn't a binary operator
mfollett: a binary operator takes two arguments, both of which can logically stand on their own 02:12
in $foo.methodname, $foo can stand on its own, but methodname can't
mfollett sorear: I didn't know that a metaoperator could only operate on binary operators
sorear . is syntactically a postfix operator, because only the left side can stand on its own
mfollett sorear: hyperoperator is a meta operator and can operate on the method invocation operator 02:13
sorear so metaoperators always attach like $foo>>.method
never like $foo.>>method
mfollett sorear: oh, I see
sorear as for why $foo*.method isn't used, I can only ask - what would $foo*++ mean? 02:14
or any non-method operator
mfollett sorear: I guess it would depend on how many ways $foo could do postfix<++>($x) 02:16
sorear: I thought $foo++ was the same as $foo.++ 02:18
sorear: or, wait, I may have just confused mysel

masak moritz_: don't think so; but I convinced jnthn that only one order makes sense.
narrower subset types "presuppose" the constraints of wider ones.
very much like binary boolean ops && || allows one to "presuppose" their lhs (or their negation, as it were) 12:54

mathw masak: What I really liked about your presentation system is that it has this wonderful aesthetic idea to it. I didn't have time to look at it properly though - what's the source file? Inkscape SVG marked up with metadata? 13:23
moritz_ I don't know how to get Match objects out of it, and dealing with Regex::Match is a pain
masak mathw: source file is in the github repo, named canvas.svg. almost all the "metadata" happens to be objects in the SVG. I only added a few .class attributes manually. 13:24
mathw nice
best to keep these things as simple as possible
masak moritz_: oh. there you go, then. thanks for reminding me. :)
mathw: I could make the whole presentation from within Inkscape. that felt liberating. 13:25
moritz_ masak: hasn't ingy written a yaml loader? I think STD exports YAML....
mathw and it looked gorgeous

13:25 masonkramer left
masak moritz_: he's started, but I haven't seen a finished product. 13:25
moritz_: do you think using Blizkost might work? 13:26
mathw although it's possible do that kind of thing in Powerpoint or Impress (although those transitions probably aren't possible), people tend to get stuck in the default slide layouts. Treating it all as one giant SVG breaks you away from that.
masak mathw: exactly.
13:26 lamstyle left
masak mathw: I expect to learn to exploit the spatial aspect more as I make more presentations. 13:27
mathw I must see if I can learn some lessons from it for my next presentation - but since that's a work thing, it's going to be in Powerpoint again. Still, I can do something a bit more fun perhaps :)
masak best of luck.
mathw in the mean time... I have software to break
and a compiler to befuddle

moritz_: because if it vanished, that is a serious breach of our deprecation policy 17:48
moritz_: perhaps a svn merge ate it. But I don't see any docs for it either, which makes me think someone did it on purpose
moritz_ dukeleto: somebody pasted a link to an example or benchmark in PIR that commented that .reverse being gone, it had to iterate over the characters 17:50

Obliterate the 'reverse' method on String PMC's.
that was Parrot r46290
isBEKaml dukeleto: there was an example PIR that clued me in on the reverse removed from the api - but I was confused when I saw that it's specced/defined in PDD28 17:52
dukeleto isBEKaml: i think it was removed because it modifies it's argument 17:54
moritz_ why not have it return a reversed copy? 17:56
dukeleto moritz_: that is what I would imagine it would be changed to. I don't see a deprecation notice, so I am thinking that perhaps it was removed incorrectly 17:57
isBEKaml I think what dukeleto was trying to say was - it was removed because it didn't conform to spec.
dukeleto isBEKaml: kind of.
isBEKaml: things that modify their arguments are hard to optimize, so parrot has been trying to minimize ops/vtables that modify their arguments 17:58
they are so-called "immutable strings" now. 17:59
I think we will add String.reverse back in, that does not modify it's argument. But I need to check with parrot-dev first
isBEKaml dukeleto: I see. Last night, I was benchmarking chomp against substr. One of the ways thrown around was using flip, which just performed horribly (pure agony) 18:00
if reverse made it to parrot, I'd happily take that around for flip. 18:01
moritz_ isBEKaml: flip is now implemented as split.reverse.join
and split('') iterates and uses substr
isBEKaml moritz_: I saw that too. Perhaps, that was why it performs poorly.
moritz_ s/Perhaps/Surely/ 18:02
isBEKaml 3 costly calls wrapped into a single method.
dukeleto Parrot has a StringIterator PMC that can be traversed in a "forward" or "reverse" directions. 18:03
But I still think String PMCs should have a reverse method.

Revert "[smartlinks] remove broken HTML links"

This reverts commit 7249b4b522142ceb4273a7b66a07a906b80381ea.
It removed too much... let's try again later
isBEKaml moritz_: there's a way to test it. It's outlined in Text-SmartLinks/script/smartlinks.pl 19:41
moritz_: damn, I'd now have to resolve external deps that I don't have currently... 19:42
moritz_ isBEKaml: there's a way to test it... push the commits, and see what perlcabal.org/syn/ makes of it :-)
isBEKaml moritz_: ah, that reminds me. I don't have commit bit since git migration. :( 19:43
moritz_ isBEKaml: what's your github ID?
isBEKaml svatsan
moritz_ isBEKaml: fixed. Welcome back to mu, roast, specs and all the rest. 19:44
dalek : 40d2add | moritz++ | util/Text-SmartLinks/lib/Text/SmartLinks.pm:
[smartlinks] another attempt to remove outdated links; also try to fix the link text
isBEKaml moritz_: you're committing them in and firing the gen script? 19:45
moritz_ isBEKaml: yes
isBEKaml I was thinking it could be something so simple as removing the prefixed ~/azawawi/html/ from the two link locations pointed in there. 19:46
line 663
after all, looking at the error page I see, that's what it seems to be. 19:47
moritz_ isBEKaml: it could be as simple now, but since azawawi doesn't seem to maintain the whole stuff, I'd rather delete the links
isBEKaml let's just remove the prefix and see what happens. 19:48
moritz_ is ~/azawawi/html/ up-to-date?
dalek : 5e58136 | moritz++ | util/Text-SmartLinks/lib/Text/SmartLinks.pm:
[smartlinks] another attempt to fix path
 19:49
isBEKaml it doesn't seem to hold anything of what we are looking at, it seems. click on summary or full test link
git still barfs at github.com clones.. should that happen? 19:51
I've switched to git://github.com clones.. 19:52
moritz_ no, but git:// clones usually work for me
19:52 orafu left
dukeleto isBEKaml: are you appending .git to the http:// clone urls ? 19:53
isBEKaml yes.
19:53 jferrero left
dukeleto isBEKaml: what error do you get? 19:53
19:53 jferrero joined
isBEKaml dukeleto: zsh: segmentation fault git clone github.com/perl6/specs.git 19:54
. It goes some way getting parent nodes and the like before hitting this.
dalek : 2966fd7 | moritz++ | util/Text-SmartLinks/lib/Text/SmartLinks.pm:
[smartlinks] put back a line which I accidentally deleted
moritz_ now much happier with the result 19:55
isBEKaml no images, mucho bettero.
moritz_ one more idea 19:56
currently the spectests are inlined
which is a lot of data
dukeleto isBEKaml: wow, fun. What version of git? You are actually getting a coredump in Git? You must be lucky.
moritz_ and makes the .html files slow to load
and means that if you use the search feature of your browser, it'll take a minute before telling you that a substring was not found
what do you think about just linking to line numbers on github instead? 19:57
19:57 Italian_Plumber left
isBEKaml dukeleto: no, I don't see any coredump file. I'm equally baffled at this behaviour. btw, git version is v1.6.4 19:58
19:59 plobsing joined
dukeleto isBEKaml: ulimit -c is probably set to 0 19:59
isBEKaml moritz_: yeah, I was wondering about that too. I've seen dialog boxes asking me whether to stop script from loading or continue on my FF window.
dukeleto isBEKaml: which prevents coredumps from being created
isBEKaml dukeleto: right.
dukeleto isBEKaml: http clone urls are very inefficient, so it is best not to use them unless you are firewalled. But that is still a strange error. 20:00
isBEKaml dukeleto: I have done this quite a lot of times before (my git fu isn't that strong or as sufficiently competent as my svn fu). and never faced this. Let me thinko about raising an issue with git folks. 20:03
moritz_ \o/ success
much faster now to search the specs 20:05
dalek : 9a57c5b | moritz++ | util/Text-SmartLinks/lib/Text/SmartLinks.pm:
[smartlinks] try to reduce page load times by non-inlining test scripts; link to them instead
isBEKaml dukeleto: I just noticed another weird thing. http clone works fine on another account here that uses bash shell. Could it be related to the $SHELL ? 20:06
my guess is, there's some env variable that's misbehaving - leading to coredump. 20:07
dukeleto isBEKaml: yeah, if you are using git completion or a git-ified PS1, that could be possible 20:08
isBEKaml moritz_: awesome. Today I learned that github highlight works by including the line numbers in the url...
dukeleto isBEKaml: yes, i love that feature
isBEKaml dukeleto: none of that.
dalek : b3c0507 | moritz++ | util/Text-SmartLinks/lib/Text/SmartLinks.pm:
[smartlinks] code cleanup
 20:10
dukeleto isBEKaml: interesting. Perhaps zsh is having a bad day. You can always backtrace the coredump if you are really interested in it .... 20:11
isBEKaml moritz_: I'm happy running yak shaving sessions with rakudo folks! :D
dukeleto makes a large wig from freshly shorn yak hair 20:12
isBEKaml watches in _no_ wonder as it falls off with a huge THUD 20:13
dukeleto: some other day. It's 2 am here and I'm in no mood to see another segfault. :) 20:15

Will look tomorrow or so. Mostly interested in being unconcious at the moment. ;-)

PhatEddy phenny: tell moritz_ his missing rakudo_test_run.tar.gz file could be caused by not having TAP::Harness::Archive installed. Without the module installed the tests are still run but you get the LTA error message. 20:55
phenny PhatEddy: I'll pass that on when moritz_ is around.
