PerlJam eric256: the perl5 docs. 14:14
eric256 thanks 14:15
wouldn't have thought to look there. lol
looks like anything outside the string should return undef and a warning...that should be easy enough to fix
PerlJam eric256: S01 says "Another assumption has been that if we don't talk about something in these 14:16
Synopses, it's the same as it is in Perl 5"
so, if you can't find something in the spec, look in the Perl 5 docs for guidance
eric256 okay, thanks

eric256 okay....so if the documentation for perl5 says one thing, but it actual does another, should we match the documentation or the implementation? hehe 14:21

and, in ng in src/builtin/control.pir they define die, warn is setup the same way but you use a different severity, it doesn't seem hard to implement 17:34
you could compare that to the old die which is in src/old/builtins-old/control.pir (i don't think this has changed much) 17:35

i'll just fudge a few more of the subs that want to use the named args version 17:38

Tene It's available to install as part of the standard repository in Fedora, yes. 17:54
eric256 do we realy need a "test".flip function? seems silly 17:55
17:55 dakkar left
eric256 and why isn't it .reverse? 17:55
PerlJam eric256: reverse is for lists 17:56
eric256: and yes, we need flip
colomon___ And it's not like implementing flip was hard work...
TimToady don't want to accidentally flip the characters when the list happens to contain one element 17:57
colomon___ (Well, I did have to write reverse first to get flip working in ng, as I recall.)
TimToady in general, any time Perl 5 overloaded an operator for two different purposes, Perl 6 has two different operators
17:58 slavik left
TimToady for instance, perl 5's scalar .. is now ff 17:58
and we differentiate x from xx now
eric256 i'm just wondering how many times people reverse a string 17:59
PerlJam eric256: you mean flip :)
TimToady makes it easy to do pattern matching from the end of the string, for one 18:00
eric256 lol i successfully made "make t/spec/S32-str/substr.t" hang
lol
TimToady another consideration is that a hardwired .flip is likely to be faster than rolling your own (though currently it's probably equivalent) 18:02
depends on how much support you get from the VM for it 18:03
18:03 jackyf joined
TimToady but mainly it's a matter of making people distinguish things that need distinguishing semantically 18:03
18:04 slavik joined
ash_ out to lunch 18:04
TimToady and we hope that learning a new name is less trouble than learning a new exception rule 18:05
certainly it makes it easier to look up if it has its own name
(admittedly, this can be taken to extremes; see PHP...)
eric256 there is an irony to getting multiple dispatch and then using different sub names for things that appear to be good candidates for multiple dispatch 18:07
PerlJam eric256: reverse isn't one of those because of the semantic confusion it causes
(if it were to behave as in per l5) 18:08
er, s/ l/l /
TimToady in short, we want Perl 6 to have different FAQs than Perl 5 did :) 18:10
we're tired of the old ones...
but yes, there are many ironies like that in Perl 6. we also make it possible to extend the language easily, and try to remove any desire to extend it by putting in most of what you need. 18:12
we put in a MOP to have world-class single-dispatch OO, then hide most of it behind multi-dispatch so that the language gets to determine the semantics rather than the class. 18:13
18:13 nihiliad left 18:14 nihiliad joined
TimToady we put in an intricate type system, and then let the user ignore it much of the time... 18:15

Contradictions "Я" Us 18:18
cognominal I would expect rule { <a>+ } being equivalent to token { <a> ** <ws> } but
rakudo: rule a { a+ }; say 'a a' ~~ m/ <a> / 18:19
p6eval rakudo 3867ff: a ␤
diakopter speaking of.. does type inference need to be spec'd any more than it is?
PerlJam TimToady: is that the Unicode version of the R meta-op? :)
18:19 payload joined
PerlJam Я seems more appropriate somehow 18:19
cognominal well, it matches 'a' instead of 'a a'
TimToady cognominal: your expectations of <a>+ are wrong
18:19 nihiliad left
cognominal I am not sure S05 is explicit about the expected behavior. 18:20
jnthn <ws> is inserted where there's whitespace in the pattern.
phenny jnthn: 30 Dec 23:27Z <mberends> tell jnthn welcome back
TimToady a rule only matchs <ws> where there's whitespace in the rule
now, [a ]+ would be a different matter
jnthn 30 Dec? Heh. I musta created a little too much optimism about when I'd be back. :-) 18:21
TimToady they didn't plant any explosives on you, did they? 18:22
jnthn heh heh
PerlJam cognominal: having a "deparse" option for regex would be useful to dispell you of your errant expectations.
jnthn No, I didn't get caught up in that one :-)
Just over in Sweden at the moment sorting various @stuff out.
Heading back home at the weekend, and then things will return to a vague state of normalish. 18:23
cognominal I should read S05 more carefully
jnthn Found myself more tired and in need of a break than expected over Christmas / new year, so took lots of rest. :-)
TimToady that's wise 18:24
you'll get more done in the long run that way
jnthn Aye.
Anyway...time for me to fine something to eat and drink here. 18:25
TimToady ponders what a backwards X metaop would look like...
jnthn back later, for some definition of later :-) 18:26
cognominal TimToady, if the {*} #= stuff is slated to disappear, what will be the canonical way to support different action classes for a given grammar. Say for a beautifier versus a compiler. 18:30
TimToady we still have per-parse action classes, and we still have actions for each complete rule 18:32
in STD I discovered that the use of {*} almost always meant I should break a rule apart, if I really needed the action
but mostly the action gets all the parts labelled well enough in any case without using {*}
18:33 taesoo joined
TimToady to the extent that the first thing viv did was throw away all the calls from {*} 18:33
(except the implied one at the end of each rule) 18:34
{*} #= was mostly a hack for bootstrapping, and it turns out we don't really need it very much, and it's cluttery looking 18:35
cognominal What is the mechanism to route a method call to the right action-class ?
TimToady the :action argument to .parse specifies it
:actions rather
cognominal ok, this pard does not change 18:36
*part
colomon___ jnthn's back, \o/
TimToady FSDO 18:37
cognominal I am not sure how an action call looks like in the grammar. Is it a closure?
18:38 uniejo joined
TimToady well, you can actually see some in STD.pm in method EXPR 18:39
push @termstack, $op._REDUCE($op<_from>, 'PREFIX');
cognominal thx 18:40
TimToady so you could insert <_REDUCE(self.pos, 'SoFar')> to get a similar effect in STD 18:41
I don't think rakudo supports _REDUCE though
the #= probably desugars to something else there 18:42
and I don't know whether it's accessible from within the grammar
but if so, you could probably write a _REDUCE method that calls it 18:43
18:44 nihiliad joined, snearch_ joined, uniejo left
TimToady again, though, that probably means you want to refactor into separate rules and get _REDUCE called automatically 18:44
18:45 uniejo joined
PerlJam TimToady: you know, I've written :action instead of :actions a couple of times myself (while coding) and been momentarily confused when it didn't work. I wonder if that's going to be a common error. 18:46
cognominal grammar A { TOP { a } }; class A1::Actions { method TOP { ... } }; class A2::Actions { method TOP { ... } }; # suppose I want an action for TOP, I still don't understand the wiring necessary to make it happen. 18:56
18:57 slavik1 joined
cognominal there is parse( 'a', :action<A1::Actions) but what I need in the TOP rule 18:57
forgot the rule keyword btw.
19:04 snearch_ left
PerlJam cognominal: methods in the Actions class that have the same name as regex in the Grammar, get called at the end of the parsing of that particular regex 19:05
(if that's what you're asking) 19:06
colomon___ ooooo!
PerlJam cognominal: also, if the regex has {*} in it, the same-named method in the actions class is called then.
(when the parse reaches the {*} token within the regex) 19:07
See S05:3781 or so. 19:08
19:08 jan_ joined
cognominal but the point of TimToady is the disappearance of the {*}. I am confused. 19:09
PerlJam {*} turned out to not be as useful (or as a hallmark of a necessary refactor), thus it's not really used much any more.
Yesterday or the day before pmichaud was talking about hooks for LEAVE, NEXT, LAST, REDO, etc. ... I wonder if this implicit {*} and the end of the regex is a specialization of LEAVE or something. Maybe it needs its own blast/blorst/whatever we're calling them these days. 19:12
oh, phaser
that's what I meant
19:13 slavik left
PerlJam Or even if the machinery that allows the same-named-method to be called should be exposed to the programmer so that they can do things like choose another-named-method or set of methods to be called. 19:14

eric256 is there anyway to fudge just a single test file? 19:59
PerlJam run fudge on just that file?
TimToady phone 20:00
eric256 i dunno how to do that though
ash_ eric256: look in t/spectest.data
thats how it knows which files to run
if you want to add/remove a file from the fudge 20:01
eric256 no i just want to fudge one...the fudging on this test file doesn't appear to be working right, so i need to keep rebuilding it
20:01 justatheory left
ash_ fudge 1 test? 20:02
eric256 one file
20:03 PZt left
ash_ i think i am not understanding what your asking 20:04
eric256 i have a test file with fudge commands in it, they arn't all working, so i need to fudge the file and look at the output, rinse and repeat until the out put is correct 20:05
PerlJam eric256: have you read t/spec/README ? 20:06
ash_ is it a file you wrote? the fudge command checks all the files listed in t/spectest.data and fudges the files listed in there 20:07
20:07 Lorn joined
ash_ after its fudged there will be a t/spec/S##/filename.rakudo instead of .t 20:07
colomon___ eric256: make t/spec/S##/filename.t will make the .rakudo file and then run it. 20:08
eric256 right, and thats working, but its slow, i just wanted to fix this one, and i can't even seem to find fudge, and its an exeisting spec
colomon___: in this case its not makeing the .rakudo file....thats kinda my problem.....mmm no errors either
colomon___ eric256: ooo, tricky. 20:09
PerlJam eric256: t/spec/fudge
eric256 oh duh found fudge...thanks perljam... didn't expect progams in there cause i'm stupid

every new thing I learn about grammars makes me want to go \o/
cognominal TimToady, btw, actions object should be probably stackable: Grammar.parse($str, :actions( <A1 A2>.>>.new ) 20:50
PerlJam cognominal: What does that mean?
20:52 KyleHa joined
cognominal that would mean that one should call a method of A1 then a method of A2 when an action method is to be called 20:52
s/one/the implementation/
PerlJam cognominal: so when a regex foo in the grammar matches, the foo method of A1 should be called and then the foo method of A2? 20:53
cognominal: if so, why?
cognominal because A2 foo may need info generated by A1 foo. 20:55
TimToady if you need such semantics, just create an actions modules that delegates appropriately
*module 20:56
20:56 jackyf joined
cognominal yes, I could do that too. 20:56
TimToady you certainly shouldn't be relying on hyperops, whose order is officially undefined
(though in this case the order is preserved by the time it gets into :actions()) 20:57
*postserved might be more accurate... 20:58
20:58 jackyf left
TimToady *curcumserved maybe... 20:58
s/u/i/ #gah
cognominal :) 20:59
20:59 bbkr joined, pjcj left
TimToady anyway, if it's a common operation to combine A1 and A2 in a standard way, there should probably be a named combinator to generate a delegational class around them 21:00
cognominal I note that when I learn something I am incapable to relate it to something I already know when it would be most useful.
TimToady not just relying on the list to apply an implicit combinator 21:01
cognominal grammar being classes, what I ask obviously fall in the realm of classes.
*falls
TimToady though in this case the action class isn't a grammar 21:02
cognominal I should learn japanese instead being tripped with these stupid flexionnal languages.
yes, but my mind was focused about grammars :)
TimToady those Indo-Europeans have a lot to answer for... 21:03
cognominal btw you should call given wa instead :)
frettled We should have a "freeze" function in Perl 6. It will "freeze" the specification and functionality for the programmer using it. :D 21:05
mberends frettled: the Linux command for that is 'ifconfig eth0 down' 21:06
TimToady cognominal: it was considered :)
cognominal I have a nice app called "human japanese" on my iPhone. It tought me a thing or two. 21:07

cognominal In France, they want to pass a law to prohibit phones in school. It makes sense because kids play with them instead of listening to the teacher, but app phones are the best pedagical tools I have ever seen and it can only get better. 21:11
frettled cognominal: I see that it's English-based; how is the pronunciation presented?
21:12 colomon___ left, uniejo left, colomon_ joined
cognominal it is english based, you click in a sentence to hear it. It is very progressive. It starts with hiragana. 21:14
frettled I was thinking about the romanization, which might lead to interesting pronunciation misconceptions. 21:15
cognominal frettled, there is light version of it if you want to try it before buying. 21:16
The author says he works on a more advanced version which will certainly be reday by the time I finish the present one. 21:17
ash_ it would be kinda cool if more schools did something different like having app's to teach
frettled cognominal: Yep, I started downloading it, but it seems to take a while, even over wifi. :)
ash_ in one of my software engineering electives next semester we are making andriod phone apps, so maybe i can try doing something like that
it can teach perl 6 :-D
frettled \o/ 21:18
ash_ hmmm wonder if i could get parrot running on the andriod...
cognominal I think pupil would be more mature if they could learn by themselves using such device and the teacher would have more time to interact with pupils.
xalbo The problem is that if the pupils are not more mature, they'll learn even less. 21:20
cognominal I don't expect much from educational institutions, I was taught using a sliding rule at a time when cheap calculators were already available.
ash_ my grandfather has a sliding rule still, he's an architect, i worked for him a few summers ago taking his hand drawings and putting them in CAD 21:21
frettled cognominal: I think I may like that app already. Thanks again. 21:24
ash_ hmm, i can use arm-eabi-gcc to cross compile from x86 to arm, wonder if that works with parrot, i'll go ask 21:25
bbkr hi. i'm in parrot_install/lib/1.9.0-devel/library (december release or rakudo) and when i do perl6 -e 'use MIME::Base64; say MIME::Base64::encode_base64("test");' i get invoke() not implemented in class 'Undef' error. should .pbc code be included/called in some special way? 21:26
diakopter I didn't know "use " was working in rakudo? /me must be behind 21:28
mberends bbkr: the 'use' command is not implemented for .pbc files yet, afaik.
cognominal frettled, you are free to /msg me the name of your favorite apps. It is difficult to find one's way in the app store when rating are done by semi-illiterate kids.
mberends 'use' does work with .pm files and .pir files that are compiled from .pm files 21:29
bbkr it loads module without error. problem is on method call.
21:30 SmokeMachine left
bbkr ok, i'll write my own pure p6 Base64 or i'll wait till it will be working. thanks. 21:30

thx TimToady
TimToady eric256: S02:1872 specs that it should return Str, actually 23:51
the error is slightly misleading, insofar as Nil is really the empty parcel, not the empty list 23:52
eric256 thats what i said... lol
well not based on a spec, just judgment hehe
TimToady Nil and () only turn into the empty list in list context
eric256 and the file that i just spent ours fixing, i rm'ed by accident 23:53
