anant_ I was reading S02, and under "Type Objects", found this statement "Any type name used as a value is an undefined instance of that type's prototype object". Should it not have been written "Any type name used as a value *refers to the singular instance* of that type's prototype object"? 09:16

anant_ anant-sogani 09:20
moritz anant_: welcome to the club. Have the appropriate amount of fun! 09:22
anant_ moritz: Thanks! I'm still confused about the type object though. Why does type object.defined return a FALSE? 09:29
moritz anant_: definedness is just the property that distinguishes types from instances 09:30
named like that for historical reasons, basically 09:31
think of .defined as .is-instance instead, and the confusion goes away (I hope)
anant_ moritz: oh ok. So, my re-write "... refers to the singular instance of that type's prototype object" is then incorrect 09:33
moritz uhm, why? 09:34
it removes the "undefined", which wasn't wrong 09:35
but IMHO it still makes it clearer that the type object is a singleton
anant_ moritz: I think removing the "instance" word makes it clearer. Something like "... refers to the type's prototype object" .. which I hope conveys the singleton idea as well 09:38
sorear either way it's wrong because it implies that the thing returned is something other than the prototype
modern p6think is that the type *is* the prototype object
Int used as a term returns the undefined prototype object named "Int" 09:39

lizmat FROGGS: with regards to 082a2a3433, I'm not sure we can get away with not implementing "use bytes" 12:16
within a scope where use bytes is active, "length" is actually number of bytes 12:17
not number of chars
so maybe add a #TODO there ? 12:18
(even though I know "use bytes" is going to be deprecated / removed in Perl 5.18+, we would still need to support it from older versions) 12:19

13:08 thou left 13:13 kivutar joined, leprevost joined
pmurias FROGGS_: why do we use a Perl6::P5World naming convention instead of Perl5::World? 13:22
lizmat perhaps because it's inheriting from Perl6::World ? 13:27
which would make the naming more logical ?
FROGGS_ pmurias: what lizmat said, there id one method we are overriding... and I guess there will be more in future 13:38
lizmat: about 'use bytes': good point, I can add the feature right away...
lizmat can you? 13:39
FROGGS_ lizmat: I think so, yes
lizmat wouldn't that require implementing the hints hash %^H ?
and something akin to local() ? 13:40
FROGGS_ I've seen right now that .chars is wrong when we have umlauts in the code and ' use utf8' is missing...
so, we need good tests for that
lizmat so you mean perl 6's .chars is wrong ?
FROGGS_ lets say it doesn't do the same like perl 5 does 13:41
perl -e 'print length "äbc"'
4
13:41 crab2313 joined
FROGGS_ perl -e 'use utf8; print length "äbc"' 13:41
3
in perl6 we have utf8 by default
but what I wanted to do right now is to call .bytes instead of .chars if 'use bytes' is in use 13:42
but we have to make a Buf first to do that
lizmat and how would you know that "use bytes" is in use? 13:43
13:43 dwoldrich joined
lizmat (as that is lexical) 13:43
moritz same as any other lexical information, really
lizmat fwiw, I can live with using .chars and a #TODO 13:44
FROGGS_ set a dynamic variable?
$*USE_BYTES
moritz for example
lizmat and parsing "use bytes" or "no bytes" would set /unset that var at compile time ?
that would work in the short term 13:45
moritz why only in the short term?
it's how we do most lexically changed behavior
FROGGS_ lizmat: it is the same for Use/no strict
moritz a dynamic variable in the compiler has the same scope a lexical pragma in the code
FROGGS_ so you can proper build the ast 13:46
lizmat wonders whether implementing the hints hash wouldn't be more flexible then
as otherwise making caller() work will become very difficult indeed with regards to (caller(N))[10] 13:47
(aka the hints hash from somewhere down the stack) 13:48
FROGGS_ pmurias: if you put them in a subdir, yes
13:53 fhelmberger joined
lizmat FROGGS: but please, please don't let me interrupt the flow of your work… a #TODO is al I really wanted :-) 13:53
FROGGS_ lizmat: that's what I did so far 13:54
the rest is a bit too complicated atm to do that properly for me
pmurias FROGGS_, lizmat: if a ruby compiler was inheriting from Perl6::World would Perl6::RubyWorld be a good name ? ;) 14:01
FROGGS_ pmurias: yesh! 14:02
lizmat FROGGS: maybe setting up the %^H hash would be a nice project to sink my teeth into 14:03
FROGGS_ lizmat: go ahead :)
moritz the hints hash has the advantage of being accessible at run time
lizmat indeed, and I know that some of TheDamian's modules use that 14:04
(as shown recently at the SPW)
tricky bit with $^H is that each call level has its own version 14:05
s/call level/subroutine/
FROGGS_ lizmat: btw, you fiddle something in the grammar, please rerun 'make spectest' before committing 14:06
lizmat ack
I wouldn't want to mess up things for other people :-)
moritz lizmat: though you know atatically at which point it's used, so you can generated it on demand 14:07
*actually
erm
*statically
is what I wanted to wrote ;-)
*write
moritz should just give up typing
FROGGS_ it is just that little changes to the grammar can make a single test work, but break everything else (precedence of the tokens and such)
pmurias lizmat: wouldn't treating %^H as compile time contextual an setting it every time we start a new scope give as Perl5 semantics? like %*LANG? 14:09
lizmat I guess the current sub has an ID that I could use as a key in a hash
14:09 colomon joined
lizmat pmurias: I would want to prevent setting it at every new scope 14:10
but I guess I should say: current scope, rather than current sub
so does the current scope have an ID?

I don't like "real objects"

moritz that's not the case with perl 6.

_sri could it be used to have a version of perl6 with do/end blocks instead of curlies?
arnsholt Possibly. I think so

arnsholt Why do you need to change the curlies to begin/end for templates though?
_sri <% do_stuff sub { %>lalala<% } %>
not cool 18:20
while in ruby you have <% do_stuff do %>lalala<% end %>
arnsholt In the simple case there, it'd be pretty simple to do the munging in the templating engine, so I assume you can have arbitrarily complex stuff inside the <%%>? 18:21
_sri yes, Mojo::Template in perl5 does it that way
moritz well, in Perl 6 you could write <% do-stuff { %> lalala <% } %> # without the 'sub'

lizmat indeed: rakudo-p5 does not require a standard perl 5 lib 21:44
mathw perl 6 grammar mutability ftw
FROGGS_ ohh yeah, it is pretty awesome
(hard for code highlighters though)
mathw Perl never was easy for highlighting 21:45
lizmat those on the bleeding edge always suffer :-)
mathw even when there was only one language in each file
adu mathw: lol
lichtkind mathw: as author of an editor you got my proof perl has the hardest highlighting of all :)
mathw Well I read some things a few years back about how you can't parse Perl 5 properly without at least partially executing it 21:46
timotimo at this point, it would be swell if one could pepper the sourcecode with hints for the highlighter
mathw Which is a bit tricky in an editor
timotimo "i know you think this is inside the quote, but the quote has long ended. you are now inside a block. please highlight my code again?"
mathw I was writing a load of Lisp a couple of months back, highlighting that's fairly easy :)
timotimo mathw: yeah, but there isn't terribly much info to be gleaned from the highlighting IMO 21:47
adu mathw: unless you have to include racket
mathw: or scribble
mathw timotimo: true... not much info in Lisp syntax at all
timotimo one can say that's a good or bad thing. a matter of taste, clearly
mathw although my biggest issue with Lisp is the dynamic typing, the syntax is quite easy to deal with really 21:48
21:50 pmurias joined
adu ok, I think the only thing I have left to do is escape-sequence, then I can upload my C11 grammar 21:50
FROGGS_ cool
mathw need to do some more Perl 6 again soon
timotimo C11? is that like C++11, but without the ++? 21:51
pmurias if I have token version { $<vstr>=[<vnum>+ % '.' '+'?] } parse '5.16' how do I extract the '5'?
adu timotimo: no, C11 is the latest C standard, C++11 is the latest C++ standard, completely different beasts
timotimo mhm
adu it was easier when the latest was C99 and C++03 21:52
timotimo r: token version { $<vstr>=[<vnum>+ % '.' '+'?] }; "5.16" ~~ &version; say $<vstr>;
p6eval rakudo ba5e04: OUTPUT«Useless declaration of a has-scoped method in mainline␤===SORRY!===␤Undeclared name:␤ &version used at line 1. Did you mean 'Version'?␤␤»
FROGGS_ pmurias: should be $<vnum>[0].ast
timotimo oh, hmm. 21:53
adu I wonder if I should use gnu's cpp instead of trying to do it myself...
arnsholt adu: If you wanna do stuff with C, I think the LLVM libs are your best bet 21:58
adu arnsholt: I've looked into it, their XML format sucks 21:59
and if I'm going to have to write my own thing, then I'd rather do it in Perl6 instead of C++ 22:00
mathw mmm 22:01
Spirit is good, but Perl 6 grammars are better
adu mathw: indeed
spirit is boost/C++ which I hate
arnsholt adu: I haven't tried the XML stuff, but libclang looked reasonable from what little I looked at it
adu the ONLY runner up I've found anywhere to Perl6 grammars is ANTLR
arnsholt It's C, not Perl 6 though. Upside is, you don't have to parse at all, just munge the AST 22:02
adu libclang isn't C it's C++
arnsholt: again, I've looked into it, and I've done more in a couple days with Perl6 than I could have in a couple months with libclang, because that's how long I tried to use libclang 22:03
arnsholt The guts are C++, AFAIK, but there's a perfectly serviceable C API
Fair 'nuff. Just figured I mention it
adu all I'm trying to do is get an XML dump of C/C++ code 22:04
I've also tried GCCXML, which does just that, but the XML format sucks 22:08
FROGGS_ XML always sucks 22:09
adu true
but it's quite powerful, being able to transform structures without knowing what they're made of
arnsholt What do you want the XML for, OOC? 22:15
adu a long project 22:20
I've been working on it for the past 20 years, and probably for the next 70 years
arnsholt Fair 'nuff =)
I wanted to extract typedefs and stuff from header files 22:21
adu to document the equivalencies of different things
arnsholt But ATM I'm sidetracked on (yet another) yak shave =)
adu yak? 22:23
22:24 colomon joined
arnsholt www.catb.org/jargon/html/Y/yak-shaving.html 22:25
pmurias if a module emulates an old api how can it determine which api version it is imported as?
arnsholt I've got a couple of yaks pushed on my stack, to be honest =) 22:26
mathw FROGGS_: my new job have got me lined up to write two giant XSLTs soon. One targetting HTML, the other XSL-FO (which I don't know yet). That'll be fun!
adu arnsholt: for example, andmap: docs.racket-lang.org/reference/pair...dmap%29%29 and predicate_on_list: www.openmath.org/cd/fns2.xhtml#predicate_on_list are not equivalent, but can both be used to implement nary comparison 22:27
FROGGS_ :o)
adu arnsholt: are you calling my project a yak shave? 22:28
arnsholt And you want to compare code for equivalence?
adu arnsholt: eventually 22:29
arnsholt adu: No, no! I'm calling -my- project a yak shave
22:29 colomon left
arnsholt In fact I'm shaving a yak, to better shave another yak to do what I started out doing 22:29
Although, that top-level task may be best considered atrophied and I've just changed primary focus
For comparing code for equivalence, I assume you're familiar with Rice's theorem? 22:30
adu arnsholt: and to be precise, sub predicate_on_list(&proc, @list) { return and_map(&proc, most(@list), rest(@list)); }
[Coke] planeteria.org/perl6/ is starting to get perl 6 content. 22:32
adu arnsholt: nope 22:34
arnsholt: I just read the wikipedia article on Rice's theorem, and it's about classification, not equivalences 22:37
arnsholt Well, one of the things that follow from it is that you can't (in the general case, anyways) prove equivalence of two arbitrary pieces of code 22:38
Which is why things like static analysis and optimisation are so hard: there are only special cases 22:39
adu arnsholt: I've heard that before
arnsholt: I didn't know what it was called
arnsholt: but I don't care, I'm doing it
that's like saying oh, parsing languages won't work, because we might get syntax errors
so we might as well not build a compiler... 22:40
lizmat is calling it an early night to accommodate for DST starting this night (in Europe) 22:43

timotimo very cool :)
masak lizmat: yes, I'm giving talks at YAPC::NA. \o/ (I hope) 22:49
lizmat masak: do you know of any perl 6 related talks that should be given at YAPC::NA, but are not currently submitted ? 22:50

masak lizmat: I know diakopter++ has been coordinating a lot, and from what I've seen of the program, it looks very promising. 22:55
timotimo masak: for my ADT module, do you think with a macro i can cause the classes to be available "at compile time" for things like multiple dispatch? i couldn't do it with a BEGIN block. (or perhaps it would have had to be something else than BEGIN? to be "at compile time"?) 22:57
22:59 cognominal joined
arnsholt BEGIN is compile-time 23:00
23:00 kivutar left
arnsholt INIT is the one that's similar to Perl 5 BEGIN, IIRC 23:00
timotimo i need to try that out again.
isn't there also CHECK time?
arnsholt And CHECK, yeah
masak timotimo: macros are conceptually at BEGIN time, yes. 23:04

masak [Coke]: re rt.perl.org/rt3/Ticket/Display.html?id=67122 and "is this the right behavior" -- I don't know. I wouldn't mind some discussion here. 23:06
timotimo how do i properly set the Branch type up at compile time when i have my %result = create_adt(...) and i have %result<Branch>? 23:07
my \Branch := %result<Branch> doesn't seem to help
masak the two possible behaviors I see are (a) the one exhibited now, "invalid UTF-8 character for UTF-8 encoding", or (b) shouldn't be able to .succ into an invalid character range, and just skip above it. 23:08
timotimo i get "invalid typename in parameter declaration" in that case
