kothog TimToady: oh? 00:28
TimToady hit "Download" on perl6.org and you should get to the rakudo page
kothog i see it.
thank you!
neat.. seemingly not much to it! i infer some effort is going elsewhere. Parrot? 00:32

cognominal I want initial feedback on a potential new feature, conditional dereference for Perl 6 before/if I flesh it, write tests case, and send it to p6.language : gist.github.com/191045 13:00
diakopter pmurias: did perl-v8 work for you yet? moritz and I had trouble on 64-bit 13:03
ruoso cognominal, I didn't quite get the feature... care to ellaborate a bit more?
moritz_ cognominal: I like the part about %thing?<foo>.other.methods aborting if %thing<foo> doesn't exist - not sure about how useful the rest is 13:04
if it doesn't exist, chances are that .other.methods throw an exception anyway
cognominal ok, so it is not utter rubish :) 13:05
ruoso although the exception will be ".other not implemented in Object"
moritz_ ruoso: right 13:06
ruoso but I'd rather have the "?" in the other side
%thing<foo>?.other
which also relates well with
%thing<foo>.?other
cognominal ok 13:08
ruoso "?." would fail if the left side is undefined
although ".?" means "don't fail if the method doesn't exist"
moritz_ which kinda makes sense 13:09
the ? points to where things might not exist
ruoso so it probably makes sense to have it "!." instead
%thing<foo>!.other.?method
where we still could leave "?." to "silently stop if the left side is undefined 13:10
13:10 PZt joined 13:12 frederico left
cognominal you meant in absence of dereferenced value, postfix ? means silent abortion and postfix ! means an exception? 13:14
ruoso yes
cognominal I like that
ruoso it's not really postfix:<!> or <?>
but it's a new "?." and "!." operator
about ??
you don't need it 13:15
because you can use the dot between them
%foo!.<bar>!.<baz>!.<bla>
%foo.<bar>.<baz>.<bla> is the same as %foo<bar><baz><bla>
13:16 frederico joined
cognominal For the ?= , it makes sense to keep it prefix 13:17
ruoso do you have an example for ?=?
er.. "?=" ?
If I get it right, the = metaop will work with ?. just as it works for . 13:18
cognominal problem of suffix ! is that it can be confused with a factorial
ruoso $a ?.= foo
cognominal, it's not suffix
and it's not just "!" 13:19
it's infix:<?.> and infix:<!.>
std: sub infix:<?.> {...}; sub infix:<!.> {...}; my $a; $a?.foo; $a!.bar;

TimToady, is it possible to implement (without changing STD) an operator at the level of the dotty, that won't try to evaluate the left side before invoking it? as the above $a!.foo idea... 13:26
hmm... dotty has its own multi token 13:27

13:50 SmokeMachine joined
ruoso cognominal, it's simply a different dotty op that returns a failure or that actively raises an excception when the left side is undefined 13:51
diakopter vijs: say 3333 + 2222 * 2
p6eval vijs 28360: OUTPUT«7777␤␤ time in interpreter: 0.032286 s␤»
ruoso it's a kind of conditional method dispatch
diakopter boggles
cognominal yes
ruoso cognominal, it's not specific to .<foo> or .[bar] 13:52
it applies to any value
$a!.foo
raises an exception if $a is undefined
pmichaud is it just changing the dispatch depending on the defined-ness of the invocant?
ruoso yes, "!." raises an exception if the invocant is undefined
pmichaud why does this need a special operator? 13:53
ruoso convenience?
pmichaud seems like we should make the convenience more generic then, and not tied to dotty
ruoso not really suggesting it to be actually core, but it certainly need to be possible to be implemente
TimToady how does it differ from '.'?
pmichaud right, that's what I'm curious about.
ruoso $a.?foo tries to dispatch a method foo 13:54
but $a might be defined or undefined
$a?.foo will fail if $a is defined but doesn't implement foo
TimToady how does it differ from $a.foo
ruoso $a?.foo won't try to dispatch foo if $a is undefined 13:55
TimToady also, you may not add a dotty beginning with something other than dot
13:55 zamolxes left
cognominal I was thinking it in the contex of .[] and .{} with special action when the value does not exist. 13:55
pmichaud this already exists: $a.?foo # doesn't dispatch foo if $a is undefined
13:55 abra left
cognominal Apparently you are thinking it in a larger context where my propostion may not make any sense. 13:55
ruoso pmichaud, er... it doesn't fail if $a doesn't have method foo
pmichaud which it probably doesn't, if it's undefined :) 13:56
ruoso but if $a is undefined it will still try to invoke foo
pmichaud, wrong...
TimToady note that dotty has to be unambiguous as both postfix and as a term
ruoso Object.?new
this will successfully invoke method "new" on Object
pmichaud because method new is defined as method new(Object:B $x: ... ) 13:57
ruoso hm?
pmichaud .new is allowed to be invoked on undefined objects 13:58
ruoso rakudo: class Foo { method bar { say "Hello" } }; Foo.bar
p6eval rakudo e52ed3: OUTPUT«Hello␤»
ruoso rakudo: class Foo { method bar { say "Hello" } }; Foo.?bar
pmichaud Rakudo isn't a valid implementation.
p6eval rakudo e52ed3: OUTPUT«Hello␤»
ruoso pmichaud, but rakudo is right in that point
pmichaud Rakudo doesn't constrain its invocants at the moment.
ruoso but the constraint is in the other direction
pmichaud is it? What's the default :D/:U/:B flag for methods?
TimToady S12 currently has :A instead of :B 13:59
pmichaud okay, :A then
but what's the default for methods that don't explicitly declare the invocant?
ruoso 'd guess :A 14:00
pmichaud anyway, "defined or fail" should probably be written as ($a // !!!)
14:00 viklund joined
ruoso "A bare Int may default differently in different circumstances. In a variable declaration, :A is assumed, whereas in a formal parameter that is not an invocant, :D is assumed." 14:01
TimToady I'd think :D would be a saner default most of the time, though it may depend on method/submethod
ruoso I think :A is a good default because it lefts :U and :D to when you need different implementations 14:03
pmichaud I think :D is the saner default
ruoso so you can still call 1.new
TimToady I think :D is a good default if you refer to any attributes in the body
pmichaud when I write a method, I don't generally expect that method to be valid on the (undefined) type object
TimToady but it's too early in the morning for me to decide anything :) 14:04
pmichaud for example, Rat.sin doesn't seem to make sense as :A
moritz_ pmichaud: only because it accessess attributes
TimToady anyway, if you guys want to define anything on the calling end, it should be a postfix, not a dotty
pmichaud agreed. the basic form would seem to be ($a // !!!)
so perhaps something like postfix:</!>
TimToady and *certainly* not an infix 14:05
or postfix:<?>
ruoso can a postfix interrupt a statement?
TimToady probably with a lookahead <!before '?'>
ruoso $a?.b.c.d
pmichaud ruoso: sure, that just parses as ($a?).b.c.d
TimToady define what you mean by "interrupt a statement" 14:06
moritz_ pmurias, ruoso: re-running the build script magically solved my problems with mildew
ruoso avoid invoking .b.c.d
pmichaud instead of "avoid invoking", how about "makes .b.c.d harmless"? 14:07
ruoso hmm... that solves it as well
14:07 ecooper joined
moritz_ maybe that problem (having an invocant chain where one might fail) should be solved with feeds instead 14:07
TimToady similar to how subscripts propagate failure
moritz_ gives TimToady cognitive dissonance 14:08
pmichaud in particular, with postfix:<?> one could write $a?.b?.c?.d 14:09
which handles the case of a method returning a failure object as well 14:10
TimToady but Failure will have very few methods defined on it anyway, and we should just make sure the original Failure doesn't get lost in the new dispatch 14:11
we need that for cascaded subscript sanity in any case
14:12 ejs1 left
TimToady (which is a really good argument for *not* accessing stacked exceptions via .[] 14:12
14:12 ejs1 joined 14:14 Util joined
TimToady since @a[$b][$c][$d] doesn't want to mess up the failure if @a[$b] doesn't exist by calling [$c] or [$d] 14:14
also probably a good argument for limiting the namespace of methods available on Failures 14:15
maybe make them all .Xfoo or some such
pmichaud TimToady: ooc, do you see Failure as more of a mixin role or as the type for most failure objects? 14:16
moritz_ is Failure ~~ Any?
pmichaud s/type/base type/
moritz_ if yes, it has loads of methods 14:17
TimToady I suppose we could put Failure outside of Any alongside junctions 14:19
pmichaud if we do that, it can't be passed to functions easily
TimToady not sure what the mixin model buys us either
pmichaud (unless they declare arguments as Object)
moritz_ unless undefined values are special-cased in type checks
pmichaud oh, correct, they are.
except that above we just said that :D is assumed on non-invocant formal parameters :) 14:20
moritz_ in Eiffel there's a curious class for undef that notionally inherits from all existing classes
TimToady a bottom class
moritz_ right 14:21
TimToady called _|_ in Haskell, I believe
pmichaud TimToady: (mixing class) I'm thinking of the case where we might want a Failure object that returns a value other than 0/""/false
*mixin
14:23 zaphar_ps joined
pmichaud I'm completely fine if we don't have such things... I was just curious if we did :) 14:23
TimToady it seems like the choice is between sending an unexpected Failure down into a non-suspecting routine, vs dispatching to the wrong routine or no routine at all
the latter seems slightly saner
especially if we can usually get it to dispatch to no routine at all
pmichaud agree
well, if arguments tend to default to :D then that would likely be the case 14:24
TimToady it would be corny if a Failure to produce a typeobject ended up invoking 'new' correctly anyway...

KyleHa Maybe that means that when you try to make an instance of it, all you get is a Failure. 14:28
TimToady not sure what the use case is for that, vs accidentally calling methods
KyleHa :D
ruoso I guess the idea of $a?.foo would be in the line of magically adding a CONTROL block surrounding that statement... 14:29
TimToady don't go there :) 14:30

pmichaud if we're modifying a "statement", that sounds like a contextualizer of some sort 14:30
still, I agree with "don't go there" :)
ruoso will there be dragons?
TimToady there will be multiplied entities 14:31
maybe we should put Failure outside of Any for a while and see how it works out 14:32
ruoso ouch
pmichaud okay, I can certainly try it in Rakudo and see what happens. 14:33
[particle] Failure is not an option?
pmichaud is Failure really a "non-instantiable role" as S02 says, or ... ?
TimToady that might be a useless generalization
not sure
pmichaud okay
Rakudo currently has it as a standard type
(not a role) 14:34
TimToady so it wouldn't be hard to move outside of Any
pmichaud but our Failure handling is a bit "whatever worked at the time" as opposed to being cleanly designed

TimToady one could, I supposed, claim there's a tree of Failure types shadowing all the Any types... 14:37
would need a use case for that approach too 14:38
pmichaud well, since any container is effectively able to hold an (undefined) Failure, I'm not sure we need it.
I suspect S04:1059 may be a fossil too (the part about "container whose type allow the Failure role to be mixed in") 14:39
TimToady iirc, we did that by morphing a Failure into a typeobject with the Failure mixin, or something like that
so it still officially passes the type test of the container 14:40

TimToady well, 1 ... *, 10 ... *+10, 100 ... *+100, 1000 seems more readable to me
14:48 rfordinal joined
TimToady ... stands for (potentially) multiple omitted commas 14:48
pmichaud okay, so my question remains then -- do we constrain the closures to immediately following infix:<...>, or can they occur anywhere in the series? 14:49
TimToady and I kind feel like I don't want ... to have to look at every value in the right list
I think if they're elsewhere in the list nobody will invoke them for you
pmichaud would it need to? I'd think it'd still be lazy 14:50

OYSTR1 especially gonorrhea
TimToady hopefully fatally attractive
OYSTR1 ooh... boiled bunnies. 17:09

TimToady congratulations, you just passed the diakopter test 17:09
OYSTR1 really? 17:10
diakopter lol
OYSTR1 that's so cool because .. um. wait. why is that cool?
TimToady it means you might like butterflies 17:11
OYSTR1 the test that I was to pass the diakopter test is a very good test to pass.
why do you think I might like butterflies?
diakopter hrm
TimToady because you passed the test
OYSTR1 why did I pass the test?
TimToady why do you ask me why did you pass the test? 17:12
OYSTR1 did you like for me to pass the test?
diakopter wget scripts.irssi.org/scripts/ban.pl
oops, ww
TimToady yes, but only if you also like butterflies 17:13
OYSTR1 what do you mean by oops?
TimToady I know what I mean when I say oops... 17:14
OYSTR1 I don't like butterflies.
moritz_ then #perl6 is not the channel for you, I fear
TimToady well, you don't *actually* have to like them
you only have to know how to be nice to them
see perl6.org
OYSTR1 I think I must like parrots. 17:15
TimToady you can say that again...awwwk
OYSTR1 I like awk. it is better than perl
TimToady now yer just bein' mean 17:16
OYSTR1 that's what she sed
TimToady you should go over to the #awk6 channel
OYSTR1 why do they need to have a channel for awk? 17:17
diakopter I don't know, why?
why do they need to have a channel for awk who?
TimToady Radio!
OYSTR1 auks are members of the puffin family. 17:18
TimToady you shouldn't believe everything you read
OYSTR1 pearls are just oyster vomit.
except oysters can't vomit. 17:19
TimToady life is complicated
diakopter I thought they were oyster kidneystones
OYSTR1 so is perl.
at least I don't have to eval awk
I wonder if auks eat oysters. 17:20
diakopter looks around for the real p6eval
TimToady are you evaling Perl 6?
OYSTR1 hot::sauce++
TimToady preferably about 500,000 scovilles
OYSTR1 wimp
habaneros and scotch bonnets, pleasse. 17:21
TimToady those are less than 500k
generally
17:21 soybean joined
OYSTR1 fair enough. 17:22
if it doesn't hurt coming out, it's not worth the hurt going in.
TimToady I am an expert on a lot of things, but not on Perl 6
to be an expert, you have to know where to go for the answers. 17:23
OYSTR1 wow. I know how to google. I must be an expert on everything.
moritz_ so who designs the designers?
OYSTR1 God is in the gasps. 17:24

syntheticore_ hello everybody 17:43
17:45 dbrock` joined
syntheticore_ i have a question regarding the spec of the Set class in S32 17:45
it says: "A Set responds to hash operators as if it were a Hash of True."
on the other hand it was said that Sets should compare their elements using === 17:46
Hashes seem to use == for membership-testting 17:47
so whats the right thing to do?
TimToady actually, they use eq by default 17:48
(Hashes)
moritz_ and eq and === are the same on Strings
TimToady but my %set{Any} should be using ===
syntheticore_ ok, thanks for clearing that up 17:49
TimToady so mutable objects stand as their own values, basically using their address as their identity
syntheticore_ the spec also says that pick() should pick keys with higher values more often. 17:51
Does this really mean the "values" of the actual keys?
TimToady when used on Bags
no, the count of the how many copies there are in the bag of that item 17:52
which is the hash value, not hte key
you ++ the value when you add a member to the KeyBag, and -- it when you take it out
it self-deletes when the value goes to 0 17:53
syntheticore_ I was wondering, because the spec gives basically the same definition for pick() for both Bags and Sets
TimToady yes, but a set elements value is always 1
diakopter vijs: my $a=sub{$a()};$a()
TimToady *element's
p6eval vijs 28359: ( no output ) 17:54
TimToady so all the members of a set have equal probability
diakopter rakudo: my $a=sub{$a()};$a()

flavioglock diakopter: hi!
perlcabal.org/~fglock/perlito.html
press "Execute" there
moritz_ flavioglock++ 20:30
flavioglock does it work?
20:31 ecooper left
Tene it works for me. 20:31
flavioglock yay!
diakopter looks good in Google Chrome, though I can't clear the Output box 20:32
moritz_ flavioglock: it seems that \n is ignored in the output
and it doesn't seem to handle errors very gracefully
flavioglock no, it doesn't handle errors at all
diakopter flavioglock: disregard our gripes :D that's great
flavioglock cool - I'll try to blog something 20:33
moritz_ flavioglock: and please tell us the URL 20:34
diakopter flavioglock: if you want bigints see how I'm doing them in my little STD->JS interpreter vijs
20:35 ruoso left 20:36 dakkar left
flavioglock diakopter: for now I just want it to be fast, in order to bootstrap in js; I'll add features later 20:36
diakopter oh
in case you're curious too, vijs uses perl (5) linked to Google's MIT-licensed JS engine "V8" 20:37
flavioglock nice - I'm using v8 at the command line too
diakopter: this compiler can also execute in perl5 and in SBCL Lisp 20:39
it could generate perl5 from the browser :)
diakopter neat... 20:40
IE can use Perl5 as a <script> engine with an IScript addin; I don't know about the other browsers 20:41
OR 20:44
you can swap out IE entirely, within IE: :) blog.chromium.org/2009/09/introduci...frame.html
20:44 kyle__ left
diakopter flavioglock: I'm very curious what v8 bug it's working around? 20:49
20:52 jauaor left
flavioglock blog: use.perl.org/~fglock/journal/39664 20:53
it seems v8 doesn't compile a 'method' until it compiles the function you are inside, 20:54
adding the reference seems to fix it
[particle] diakopter: point of note, www.vijs.ca/ is the website for my favorite indian food on earth
20:55 payload joined
diakopter ah, trick the JIT 20:56
flavioglock diakopter: I didn't investigate much, because it worked :)
diakopter [particle]: well, it needs a different name
my js interpreter, I mean
er, Perl6 interpreter, I mean. 20:57

moritz_ can anybody please check if the latest rakudo runs t/spec/S32-num/rat.t fine? 20:58
on my local machine it dies at the end with "Could not find non-existent sub done_testing"
20:59 pmurias joined
pmurias flavioglock: hi 20:59
phenny pmurias: 19:38Z <diakopter> tell pmurias sure, if you want... there will likely be additions/fixes to viv that need migrated over though
pmurias flavioglock: is mp6 bootstraped in js?
flavioglock pmurias: I didn't try yet, but it should work 21:00
I'll test tomorrow, I need to sleep
pmurias so how does perlito work?
flavioglock I used the perl5 compiler, with the js emitter
21:00 molaf left
flavioglock the js compiler should compile itself, but I didn't try yet 21:01
pmurias what's your plan for mp6? 21:02
21:02 icwiener left 21:03 dbrock` joined
flavioglock I have a precedence parser I need to merge in, and a few more backends I'd like to test 21:03
maybe merge some features back from kp6, later 21:04
21:06 lmc joined

p6eval rakudo 0eaf62: OUTPUT«abc␤»
flavioglock I worked a bit on Clojure and I also tried desugaring to execute on Rakudo 21:24
21:25 alester left
flavioglock rpython also looks interesting 21:25
diakopter how about C#/DLR :) 21:26
moritz_ rakudo: say 1/2 eqv 1/2 21:27
p6eval rakudo 0eaf62: OUTPUT«infix:<eqv> is only implemented for certain special cases yet␤in sub infix:eqv (src/gen_setting.pm:2073)␤called from Main (/tmp/KzOtmXVNGs:2)␤»
flavioglock C# would be nice to have, but I don't have an application for it - so I'm not much motivated 21:28
it has a low fun-factor 21:29
diakopter C# has perhaps a too-high fun-factor for me. 21:30
flavioglock I experimented with modifying the v8 grammar to accept mp6
this has a high fun-factor, but it would be impossible to maintain across v8 releases
too high? 21:31
diakopter yeah, as in, I can't afford it. :) 21:34
moritz_ should 2, 4 ... *+2, 7 end in 6 or in 8? 21:35
pmichaud should be 2, 4, 6, 7
moritz_ pmichaud: thanks
flavioglock pmichaud: hi! 21:37
pmichaud hello, fglock. nice work on perlito
flavioglock thanks :)
moritz_ and 1, 3 ... +2, -2 would be infinite, right?
pmichaud do you mean *+2 ? 21:38
or +2
moritz_ *+2
pmichaud I would take it to be 1, 3, -2
flavioglock zzz &
21:38 flavioglock left
pmichaud oh, wait 21:38
hmmm
moritz_ oh, uhm.
pmichaud yes: 1, 3, 5, 7, 9, ... 21:39
(infinite)
21:42 PZt joined 21:43 PZt left
moritz_ currently trying to test and implement it... 21:46
the previous signature was (@lhs, Code $generator) 21:47
now I added (@lhs, Code $generator, $limit?)
$ ./perl6 -e '1, 2 ... *+2, 8' 21:48
No applicable candidates found to dispatch to for 'infix:...'
dalek kudo: c584dc6 | moritz++ | src/setting/Operators.pm:
remove some duplicate code in infix:<...>
kudo: 0220cc2 | moritz++ | src/setting/Operators.pm:
implement infix:<eqv>(Rat, Rat)
moritz_ so, it builds a list of the RHS too, I assume
so this is going to be ugly 21:49
pugs_svn r28373 | moritz++ | [t/spec] initial tests for series operator with limit 21:50
TimToady I find the 2,4,6,7 semantics to be surprising
I was thinking of the number as a pure limit, thrown away 21:51
moritz_ bs in, bs out ;-)
the other logical thing to do would be to return 2, 4, 6, 8 21:52
TimToady I think it's 2,4,6
moritz_ ie take the first produced value for which the comparison has changed
then our simple scheme won't work 21:53
ie the "compare $first with $last, and keep going until $latest cmp $last is different"
21:54 tak11 joined
moritz_ we'd have to special-case inclusion of $latest if $latest cmp $last == 0 21:55
fine by me if specced
TimToady note the sample code in the spec essentially does that
moritz_ but means that 1, 1 ... $complicated_closure, 1 might not be consistent
moritz_ looks at the spec again 21:58
TimToady it always quits on $new === $old as well as on equality
moritz_ what are !after and !before?
TimToady *inequality with endpoint
!after is before or eqv
in most number systems :) 21:59
moritz_ so it's $new cmp $old <= 0?
TimToady depends on the direction
we could, I suppose write 1,2 ... $closure => $limit, 10, 11 etc. 22:01
the pair kinda looks like "going to the limit"
moritz_ S03 has the example 'z' ... 'a' # z y x ... a 22:02
which multi should handle that? 22:03
TimToady ... is always two lists
moritz_ ok
TimToady or more, since it's list associative
22:04 M_o_C left
TimToady so more like X or Z 22:04
22:04 kothog left
moritz_ so it doesn't really do "intelligent" multi dispatch, it just unpacks its arugment and tries to be smart with it 22:04
TimToady yes
but maybe we should have a way of combining the closure and the limit into a single argument, such as with pair notation 22:05
moritz_ it would emphasize that the end point is not always part of the result list
TimToady so it's clear the $limit isn't part of the next sequence unless the generator generates it
but I was mostly assuming that people wouldn't write limits that don't match exactly, in which case maybe the comma reads better 22:07
22:08 KyleHa1 left
TimToady or we find some way of hacking: 1,2,3 ... *+1 <= 10, etc. 22:08
moritz_ 1,2,3 ... *+1 also * <= 10 22:09
22:09 omega left
TimToady glares suspiciously at a round hole and a square peg 22:09
moritz_ well... not really
pugs_svn r28374 | moritz++ | [t/spec] more series tests straight from the spec. 22:10
r28374 |
r28374 | Also correct one test as clarified by TimToady++ on IRC
22:10 omega joined
moritz_ it's still not quite clear to me how dispatch to ... works 22:12
it has to receive a raw capture and unpack that
TimToady or parcel
moritz_ but if it does, how can it know which parts are left of the first ..., and which parts are right of it? 22:13
japhb I need a linguist's brain: What is the term for a type of test that is exploratory? The little scripts you write when you just want to see if something is feasible, and generally how you would do it, before you even start on the real prototype? 'Proof of concept' close, but I think of that as something used to prove some entire project is doable. I'm talking about some little piece of it. Like "How do I do async DNS lookups on this pl
atform" when you're really writing a client app for some protocol. So far we in #parrot have come up with 'throwaway', 'scribble', and 'doodle'. Anything better?
TimToady one capture for each arg
moritz_ or is that handled by multidimensionality, which rakudo doesn't handle yet?
ok
TimToady $cap ... $cap ... $cap
well, a slurpy of captures, maybe we could force that for now 22:14
moritz_ so nothing I can implement in Rakudo today. Sigh
TimToady how does it do Z?
rakudo: say 1,2,3 Z 4,5,6
p6eval rakudo 0eaf62: OUTPUT«sh: ../p/bin/perl6: No such file or directory␤»
moritz_ probably wrong :)
rakudo: say 1 22:15
p6eval rakudo 0eaf62: OUTPUT«sh: ../p/bin/perl6: No such file or directory␤»
TimToady ... is the same precedence as Z
japhb Any ideas? TimToady, anything?
TimToady sec, brain still on ...
22:15 iblechbot left
japhb ah 22:15
TimToady probes 22:16
japhb oooh
I like that one. 22:17
TimToady depends on whether you're the prober or the probee
japhb heh
And your particular predilections as well, I'd assume ...
Anyway, I think that one will do nicely. Thanks, TimToady++ 22:18
moritz_ oh, it seems that infix:<Z> works pretty well in Rakudo, but it's a functionality not available from Perl6, only from PIR
and I'm not going to write the series operator in PIR. That's way too painful :)
rakudo: say 3 22:19
p6eval rakudo 0eaf62: OUTPUT«3␤»
TimToady I guess rakudo needs parcels...
moritz_ aye 22:20
TimToady or at least some way of turning an argument list into a scalar iterator 22:21
sjohnson trusty $i variable
TimToady rakudo: say i
p6eval rakudo 0eaf62: OUTPUT«Could not find non-existent sub i␤»
moritz_ well, I hope that jnthn++'s grant proposal is going to be accepted
TimToady rakudo: constant i = 1i; say i

ruoso boa noite 22:36
jrtayloriv Are each of the alternatives in this rule tested as if they have written before them? --> pastebin.ca/raw/1575841 ... that is, does :sigspace replacing whitespace with '<.ws>' immediately after the '|'? 22:40
s/they have/they have <.ws>/ 22:41
So, for example, if I didn't want to allow a <list> with whitespace before it to match, would I have to do '|<list>' instead of '| <list>'? 22:42
TimToady that looks like it should be a token to me 22:44
and let the rule that calls it eat the spaces
22:47 crythias joined
crythias perl6: say 3 22:47
p6eval elf 28374, pugs, rakudo 0eaf62: OUTPUT«3␤»
jrtayloriv TimToady, OK. So you are saying that if I wrote 's_expr' as a token which was called from 'rule TOP', then all of the whitespace that came before the <s_expr> would be eaten by TOP, so I wouldn't have to worry about them, correct?
22:49 pmurias left, crythias left 23:00 rhr joined, SmokeMachine left 23:03 jauaor joined 23:05 rhr_ left, frederico left
TimToady jrtayloriv: right, basically things tend to naturally fall into patterns that want to match ws and those that don't 23:12
though often a "token" will call a subrule that matches whitespace internally 23:13
so parentheses will typically be a token, but call a subrule that matches whitespace around a subexpression.
though of course Lisp has its own rules 23:14
