Set by TimToady on 25 January 2008.
pmichaud and earlier today I couldn't find any examples of .join on a list. 00:00
TimToady pugs: say list('foo').join('')
exp_evalbot OUTPUT[␤]
pmichaud (in the synopses)
TimToady pugs: say list('foo',).join('')
exp_evalbot OUTPUT[␤]
TimToady pugs: say ('foo','bar').join('')
Auzon pmichaud: S29 does define join on in the List section, down a few pages.
exp_evalbot OUTPUT[foobar␤]
TimToady definitely something bogus going on there... 00:01
Auzon pugs: say ('foo').join(',');
exp_evalbot OUTPUT[,␤]
Auzon pugs: say ('foo',).join(',');
exp_evalbot OUTPUT[foo␤]
bacek_ pugs: say sort
pmichaud Auzon: what line number?
exp_evalbot OUTPUT[*** No compatible multi variant found: "&sort"␤ at /tmp/jEeIhA8Dm9 line 1, column 5 - line 2, column 1␤]
Auzon pmichaud: Not sure, since I don't know where S29 actually lives as a POD 00:02
pmichaud the only 'join' I could find as a method is
our Str multi method join ( $separator: @values )
bacek_ pmichaud: 'sort' shouldnt work without arguments :)
pmichaud and if $separator is the invocant, I'm pretty sure it's not a List.
Auzon pmichaud: That's in the List section. So you're right. :)
Err, rather, that's the one I was referring to 00:03
But I didn't look at the type.
pmichaud I didn't look at the section. :-)
TimToady pugs: class Object is also { method join ($x) { (self,).join($x) } }; say 'foo'.join(',')
exp_evalbot OUTPUT[*** ␤ Circular class inheritance detected for class 'Object'␤ at /tmp/o3eBxcnZxM line 1, column 23␤]

exp_evalbot OUTPUT[*** ␤ Circular class inheritance detected for class 'Object'␤ at /tmp/aOYFbjBNRc line 1, column 23␤]
TimToady pugs: class Any is also { method join ($x) { [self].join($x) } }; say 'foo'.join(',') 00:04
yipee!!
Auzon Where is S29.pod live as a POD? I don't see it in the Pugs repo or the other syn one I checked out 00:05
pmichaud it's not S29.pod
docs/Perl6/Spec/Functions.pod in the pugs repo
TimToady it's Functions.pd
*pod
Auzon Alright.
TimToady pugs: say 42 00:06
pmichaud TimToady: I think you infinite looped pugs.
Auzon sheesh, you broke it
TimToady maybe I took NL off the power grid by redefining Any...
pmichaud I think that [self].join($x) might look self-referential. 00:07
er, recursive, even.
TimToady should just end up calling Array.join
Auzon pugs: say 42
TimToady I think I took down the power grid...
Auzon I'm logged into the server, so nothing too bad happened... ;) 00:08
TimToady probably running on an emergency generator :)
Auzon evalbot hung, I think. 00:09

stevan_ TimToady: re: parameterized roles 01:14
we have faked them a little before
MooseX::Storage does it with the Storage function which takes some args and returns a list of roles 01:15
so you can do
with Storage(io => 'AtomicFile', format => 'JSON');
that uses the MooseX::Storage::Format::JSON and MooseX::Storage::IO::AtomicFile, etcetc
there is no hooks available yet for the role application process though, so its limited in what it can do 01:16
people have asked for hooks, but no one has a real use case yet so I am currently punting 01:17
so if you have a more specific use case then i am all ears :)
I think really I need to define the limits of parameterized roles then I can work out how it could be implemented 01:18
full generics would be ... tricky
but something close to that could be doable I think 01:19

pmichaud Auzon: so, are the tests following what S29 says, or do we need to update S29 to match the tests, or ... ? 02:27
Auzon The best thing would be to clarify the behavior of "foo".join, as well as the type given in the code example 02:29
TimToady++ agreed that "foo".join(':') shouldn't be any different from join(':', "foo"), and ("foo").join(':') shouldn't be different than ("foo",).join(':') 02:30
pmichaud what about 'foo'.join(@array) ?
TimToady probably fails from too many arguments 02:31
pmichaud okay. So S29 is probably wrong there.
our Str multi method join ( $separator: @values ) should be our Str multi method join ( @values : $separator = ' ' ) 02:32
are we still doing the "liberal edit" policy to S29? 02:33
TimToady yes
pmichaud does anyone review the edits? more to the point, is there a way to get svn diffs via email the way that parrot's svn does?
TimToady what is this "email" thing of which you speak? :) 02:35
pmichaud it's a very handy mechanism for reviewing svn diffs. Almost as good as Atom or RSS feeds :-)
Okay, I'll start taking liberties with S29 then :-) 02:36

pmichaud so, we're doing map/join/grep/etc. on non-list values?
TimToady some of them seem to coerce to list/array, and some don't 02:39
pmichaud which do, which don't? ;-)
TimToady what I was saying earlier is that we should be more consistent
and make Object do the "default" coercion
pmichaud I'd agree with that. Feels slippery-slope-ish though.
TimToady much like default + coerces
pmichaud for example, 'foo'.sort ? 02:40
TimToady as long as the defaults are out in Object or Any or some such, any subclass can override
so just as the default is infix:<+> (Any $x, Any $y) { Num($x) + Num($y) } or some such 02:42
Auzon Can we easily coerce from a Str or Num to a List?
TimToady likewise method join etc in Object can just coerce to list/array or whatever, depending on what people will expect
@("foo") 02:43
lambdabot Unknown command, try @list
pmichaud okay. it sounds a little like "arbitrary list", though.
i.e., join coerces, but some other method might not
TimToady it really depends on whether the language as a whole is "claiming" the name for a consistent meaning 02:45
just as it has claimed + for numeric additoin
join should combine pieces, and any individual piece should consider itself a degenerate case
sorting one element is not very interesting either :) 02:46
pmichaud how about .kv, .keys, .values, .pairs?
TimToady $x means 0 => $x as a key/value pair, maybe 02:48
Auzon or $x => 1?
or $x => undef
TimToady assuming $x-as-a-list means [$x] or some such
Auzon: your view would be more useful for hash coercions, where sets are considered keys of hashes 02:49
Auzon hm, but if we do that, then odd-element lists to a hash would be legal. Right? 02:50
TimToady only if we automatically coerce each element in the list, which I don't think we are 02:51

Auzon :-/ It's hard to tell where to say that "this is a one element list" and "this is a scalar" 02:54
e.g. $x versus ($x) versus ($x,)
TimToady only the last is a list by nature 02:55
pmichaud $x and ($x) are the same.
Auzon It also seems like the function calls are more forgiving of this distinction than the OO versus 02:56

Minthe So until today I was searching how to fix Invalid grammatical category: "Bool"

Minthe Today I found this site: www.nntp.perl.org/group/perl.perl6....g1876.html
lambdabot Title: building pugs under Fedora 9 doesn't work - nntp.perl.org, tinyurl.com/5oj5mp
Minthe I'm using Debian ghc 6.8.2-5
But I think the issue is the same... 08:40
moritz_ yes
Minthe So could you tell me what is the latest working revision?
moritz_ around r18093, with ghc 6.6.1
moritz.faui2k3.org/debian/pugs/ # debian packages
lambdabot Title: Index of /debian/pugs
moritz_ not very good, but they work for me 08:41
ruoso pmichaud, for 'foo'.join(';') to work, join must be: our Str multi sub join ($string, @elements) is export {...}
because join won't be found in Str, then it will fallback to sub-dispatch
Minthe I successfully compiled cpan stable, but it is too old.
08:41 pmurias joined
ruoso pmichaud, I don't think Str will ever be the invocant of "join", unless of course we add the method 'join' on Str instead of Array 08:43
which might make sense, but it probably doesn't... falling back to sub-dispatch solves the problem just fine... 08:44
Minthe Excuse me, but why moritz.faui2k3.org/debian/pugs/r19915/ is 6.2.12? CPAN stable version shows 6.2.13... 08:45
lambdabot Title: Index of /debian/pugs/r19915
moritz_ Minthe: probably because I used the wrong version string
Minthe: it was one of the first debian packages I built, and I'm not very good at it ;) 08:46
Minthe So if I install pugs_6.2.12-2_i386.deb, pugs -v will show 6.2.13?

ruoso pmurias, so Foo::bar() would involve finding the class, asking which package it is in, and then looking up for the sub bar? 10:10

pmurias ruoso: the namespace entry can have the package also 10:19
ruoso pmurias, but do you agree on the sub/method thing I said? 10:24
that there can be subs and methods with the same name
and subs are registered in the package
therefore it will only be invoked as it fallsback to sub-dispatch 10:25
and what about submethods? do they live in the package? or in the class?
the specs seem to imply that they are just subroutines that might have an invocant.... 10:26
but what happens when someons calls a submethod without an invocant? 10:28
if they live in the class that wouldn't be possible...
but it would require yet another storage facility in the protoobject 10:29
pmurias ruoso: submethods are non-inheritable methods 10:50
so they should be stored in the metaobject 10:51
not much should live in the protoobject 10:54
ruoso pmurias, that actually depends on the implementation.. but you think it should not live in the package... 10:55
pmurias it is? 10:57
what do you mean by it
?
ruoso pmurias, in SMOP, for instance, the HOW won't have a storage itself... 10:58
the storage will be in the protoobjects...
because it's a prototype-based OO
not Class-based OO
(for the default implementaitons, I must say) 10:59
but the definition of it is in the package or not is more important...
because it then would moving the submethods out of the class/prototypes
and registering then as subroutines in the packages 11:00
that's a more important distinction
pmurias is metadata a pointer?
ruoso in SMOP p6opaque?

ruoso I was thinking about the 'foo'.join(', ') thing 12:52
if we solve it by adding an additional signature to 'our multi join' 12:53
we will have to do it to almost every method in array
and that doesn't seem very nice... 12:54

pmichaud ruoso: that was my concern as well (and the focus of my comments with TimToady) 12:55
ruoso 'foo'.join(',') is the simplification of what ('foo').join(',') means
pmichaud er, ['foo'].join(',') 12:56
moritz_ ruoso: 'foo' and ('foo') are the same thing
pmichaud since ('foo') is still a Str
ruoso but (1,2,3).join(',') is valid
right?
pmichaud yes, because (1,2,3) is a List
pmurias so 'foo.join(',') is 'foo'?
12:57 renormalist joined
pmurias so 'foo'.join(',') is 'foo'? 12:57
ruoso so it's expected that (1).join(',') works
pmichaud pmurias: according to yesterday's discussion, 'foo'.join(',') is indeed 'foo'
i.e., 'foo' is treated as a 1-element list
same as 'foo'.elems returns 1
ruoso yes... 12:58
moritz_ should that work with any $foo, or only with strings?
ruoso and if to do that we start adding signature variations on the array and hash methods
it will be a ugly hack..
moritz_, any foo
moritz_ urgh, that's really ugly
probably DWIM, but still ugly 12:59

ruoso kp6++ that was really funny

ruoso maybe there could be an additional fall-back on the method invocation 13:02
which would be to create a single-element list and call the method there 13:03
moritz_ which then again has a fallback to sub call
ruoso yes 13:04
it sounds fat
but prettier than dozens signature variations
moritz_ I think we should avoid allowing "foo".join('bla'), and just be consistent about what returns a list 13:05
ruoso the problem is that ($foo) is not a list initializer
($foo,) is
moritz_ that'w hat @(foo) and [$foo] and ($foo,) are there for 13:06

Juerd As long as it's not pythonesque "separator".join(list), anything works for me :)

pmichaud seems to me that (1,2,3).WHAT and (1,'asfsd').WHAT return the protoobject for List
13:45 hcchien left
ruoso pmichaud, but (1,2,3) can be optimized for a compact storage, whereas (1,'absf') can't 13:45
when it's optimized, does it still returns the same WHAT?
pmichaud depends on whether that optimization is to be user-space visible or not. 13:46
ruoso heh.. that's my question, actually ;)
pmichaud I would probably say "not"
moritz_ I don't think it's allowed to be user visible
ruoso that will make many things much harde 13:47
or not... 13:48
but if it's hidden, how can it be introspected (at some level it needs to be)
WHAT is supposed to be the entry point for that introspection... 13:49
pmichaud actually, HOW is for introspection. 13:50
ruoso of the metaclass
not the prototype
they are different thigns
pmichaud what kind of introspection are you referring to? 13:51
13:51 ispy_ left
ruoso I want the find what the object really is 13:52
pmichaud I think that's HOW.
ruoso for class-based OO 13:54
not for prototype-based OO
pmurias can't prototype oo have unique per object HOW's?
ruoso that's the actual difference between them 13:55
the HOW on a prototype OO will be probably be something like Class::C3
while the prototypes are the things holding the actual definitions 13:56
pmichaud ...the things holding the actual definitions?
PerlJam ruoso: btw, congrats on the grant
ruoso PerlJam, thanks ;)
pmichaud, yeah... the method object will be stored in the Foo prototype 13:57
not in the metaclass
pmurias ruoso: i'm not sure you use the definition correctly 13:58
cj ruoso: are you yas' grantee this year? 13:59
pmurias en.wikipedia.org/wiki/Prototype_bas...rogramming
ruoso cj, yas?
pmichaud from S12:
MyClass.methods() # call MyClass's .methods method (error?) 14:00
MyClass.HOW.methods() # get the method list of MyClass
ruoso "Which of these items are actually part of the .HOW object and which are delegated back to the package and prototype objects is up to the MOP."
pmichaud note that the list of methods is part of the metaclass, not the protoobject
pmurias pmichaud: metaobject not metaclass
pmichaud from S12: 14:01
Every class has a HOW function/method that lets you get at the class's metaobject, which lets you get at all the metadata properties for the class (or other metaobject protocol) implementing the objects of the class:
MyClass.methods() # call MyClass's .methods method (error?) MyClass.HOW.methods() # get the method list of MyClass
note "or other metaobject protocol"
ruoso but .HOW does not stablish identity 14:02
while .WHAT seems to serve for this sole purpose
pmichaud .WHICH is identity
ruoso pmichaud, of the object, not of what it is 14:03
pmichaud well, I can see things going either way. I'll leave the rest up to the language designers. :-) 14:05

ruoso where did pmurias go? :) 14:06
@tell pmurias why do you think I'm not using the idea of prototype oo correctly? By reviewing some texts about it, I can fit with pretty much confidence with prototype oo by delegation (which is actually a key to get the repr thing working) 14:12
lambdabot Consider it noted.
ruoso although It explicitly forbids a defined object to have extra definitions just to avoid that someone accidentally turn Undef into defined 14:13
but that is basically the only reason
hmm... maybe I could make that forbiden just one-way 14:37
which would be to define a object that have definitions
14:37 pmurias joined
ruoso but still allows adding definitions to a defined object 14:37
pmurias ruoso: re where i was, i was rebuilding the kernel 14:38
lambdabot pmurias: You have 1 new message. '/msg lambdabot @messages' to read it.
ruoso ah... you're not nija enough to replace the kernel without rebooting... ;) ;)
s/nija/ninja/ 14:39
heh
pmurias re why are you using the definition incorrectly: prototype oo is commonly a language feature not a way of implemenation 14:43
you don't have classes in prototype oo, and as such the protobject dosn't make sense at all 14:44
ruoso uh? 14:47
you lost me.... the protoobject doesn't make sense in prototype oo?
pmurias yes 14:48
ruoso why so? as I said, I'm implementing delegation...
pmurias the protoobject is a undefined object used to call methods from the class it belongs to, right? 14:49
ruoso the protoobject is the undefined version of this object
you can do a lot of things with it, including cloning 14:50
[particle]1 (01:50:08) moritz_: and rakudo parses 'our' as a sub - ouch
no, that's a parrot error
moritz_ ok
pmurias ruoso: protoobjects make sense in prototype oo as a way of briding between class-base oo and prototype oo
ruoso pmurias, they make sense when you work with delegation... 14:51
14:51 [particle]1 is now known as [particle]
ruoso we only made a restriction to avoid a user from defining undef... 14:52
but otherwise, you would be able to say Object.BUILD
and Object would be defined
pmurias but with prototype oo i could build my object like my $object = $foo.clone();$object.HOW().methods.push(...) 14:54
ruoso and you will be able to do that with SMOP 14:55
we had set a restriction on that only to avoid defining undef...
but I think I'll limit that restriction to defining objects with definitions
and not the other way around
or maybe even removing that restriction entirely 14:56
pmurias &
ruoso and let the user shoot a bazooca in his feet by doing Object.BUILD 14:57

TimToady subscripts are allowed to assume at compile time that they will be bound to a slice context
so the optimizer can work with it
diakopter reads about semilist in STD 17:18
TimToady otherwise all you can do with a semilist is turn it into List of Capture and defer the decision whether to flatten or not
ruoso TimToady, but is the (1,2,3 ; 4,5,6) format valid?
TimToady depending on binding

TimToady not necessarily
b_jonas hmm
TimToady again, it depends on the binding
diakopter eek
ruoso that seems very hard to implement ;)
TimToady you did read the synopses, didn't you? :) 17:21
pmichaud a((1,2,3),(4,5,6)) will act as (1,2,3,4,5,6) if bound to a slurpy array
diakopter adds a few more passes to the ROADMAP
TimToady but if the sig is ($,$) you get two lists
pmichaud you also get two lists with (@,@)
TimToady indeed
b_jonas S03: The context determines how the expressions terminated by semicolon are interpreted. At statement level they are statements. Within a bracketing construct they are interpreted as lists of Captures, which in slice context will be treated as the multiple dimensions of a multidimensional slice. (Other contexts may have other interpretations or disallow semicolons entirely.)
diakopter ah ok; that answers my original question. 17:22
b_jonas lists of Captures? wierd
I like the parenthetical remark
ruoso pugs: multi sub a (@a) { 1}; multi sub a (@a, @b) { 2}; say a((1,2,3),(4,5,6))
exp_evalbot OUTPUT[2␤]
b_jonas basically I think semicolons should be "usually" an error inside parenthesis so you can easily catch unpaired open parenthesis in expressions 17:23
TimToady it would be a good place for a "suppose" point, if the parse does fail later
in which case it will still tell you exactly what went wrong, most likely 17:24
diakopter pugs: multi sub a (@a) { 1}; multi sub a (@a, @b) { 2}; say a((('flatten','me',3),(4,5,6)))
exp_evalbot OUTPUT[1␤]
diakopter nifty. 17:25
TimToady but as you see with (say 3; say 4), it has the use of terminating the first say's argument list and then continuing the outer list
b_jonas TimToady: yeah, especially if it also watches indentation for suppose points
hmm

b_jonas where is that (say 3; say 4) defined in the synopsis?
what I quoted is I think all it says about the semicolon 17:26
pmichaud b_jonas: S04: Note though that the first expression within parens or brackets is parsed as a statement, so you can say:
@x = 41, (42 if $answer), 43;
lambdabot Maybe you meant: . ? @ v
pmichaud and that is equivalent to:
@x = 41, ($answer ?? 42 !! ()), 43
lambdabot Maybe you meant: . ? @ v
b_jonas oh no
that's exactly what makes error catching hard
TimToady so you suppose 17:27
diakopter suppose harder
pmichaud also: A do is assumed immediately after any opening bracket,
...
b_jonas (though it's even worse in ruby where newlines are converted to an implicit semicolon in lots of places)
diakopter {bareblock}\n <- statement 17:28
?
b_jonas brace is ok
let me check
S04 says: In Perl 6, the bare block is not a do-once. Instead do {...} is the do-once loop (which is another reason you can't put a statement modifier on it; use repeat for a test-at-the-end loop). 17:29

b_jonas hmm
diakopter the block was declared only?
pmichaud that's not a bare block.
a bare block is a block that occurs at statement level. 17:31
b_jonas so a brace can be a do-once, a subroutine, or a hash?
pmichaud inside of parens, it's a closure.
b_jonas fun
diakopter oh...
pmichaud I should say.... inside of an argument list, it's a closure
[particle] braces are always a closure
b_jonas I don't get it then 17:32
so a bare block is never a do-once, right?
pmichaud { my $a = 3; say $a; } # bare block, executes immediately
TimToady it works as in Perl 5, except for the fact that it's not a loop
ruoso a bare block is a block in void context? 17:33
b_jonas ah yeah
found it
Although a bare block occuring as a single statement is no longer a do-once loop, it still executes immediately as in Perl 5, as if it were immediately dereferenced with a .() postfix, so within such a block CALLER:: refers to the scope surrounding the block.
in S04
pmichaud b_jonas: correct.
b_jonas hmm
ruoso so a block in void context is executed immediatly...
TimToady it's not the void context
ruoso it's syntatic only? 17:34
TimToady it's being part of <statelist> rather than <semilist>
pmichaud it's the bare block as a single statement
b_jonas pmichaud: but wouldn't that conflict with the above thing you said that "the first expression within parens or brackets is parsed as a statement"
?
17:34 hcchien_ is now known as hcchien
TimToady that's a semilist 17:34
pmichaud say({ ... }) isn't inside "parens".
here the parens are part of the argument list.
b_jonas oh, so "inside parens" doesn't apply to argument lists
I see
that's just like ruby
17:34 dalek left
b_jonas (probably stolen from there as well) 17:35
TimToady nope
I've never actually looked at how ruby parses
pmichaud and the "inside parens" doesn't say anything about when the block is executed -- just how it's parsed.
17:35 dalek joined
b_jonas but then 17:35
what does "or brackets" mean in that?
what kind of brackets?
pmichaud [{ ... }] 17:36
b_jonas but meaning what?
array constructor?
pmichaud sure.
TimToady it's a semilist, not a statelist
b_jonas that doesn't seem to make sense to me
why array constructor in particular?
how's that different from any ordinary function call arglist or circumfix operator? 17:37
bare parens special, I get that
but array constructor?
TimToady bare [...] is always an array composer
pmichaud example: @x = 41, [42 if $answer], 43; 17:38
b_jonas strange
TimToady that's either 41, [42], 43 or 41, [], 43
b_jonas I don't get what that's good for 17:39
TimToady modifiers inside brackets are good for various forms of list comprehensions
ruoso but the difference from p5 here is in accepting "if" there, not the array construct itself, right? 17:40
17:40 sscaffidi joined
b_jonas list comprehensions... hmm... maybe 17:40

ruoso buubot, eval: $a = "0 but true"; [do { 3 unless $a }] 17:42
buubot ruoso: ["0 but true"]
diakopter I'm getting the feeling the type checker will need to employ brute force. 17:43
ruoso TimToady, but is a(5 if $foo) valid also? or is that specific for the array constructor?
pmichaud the thing in the parens is a semilist
so yes. 17:44
ruoso ah... ok... for one second I understood it was something specific...
TimToady there are very few specifics in Perl 6 :)
pmichaud in STD.pm: token postcircumfix:sym<( )> ( --> Methodcall) { '(' <semilist> ')' {*} }
diakopter that's like God saying the Bible has very few specifics. 17:45
ruoso hehe
[particle] it's <semispecific>
TimToady it's just that everyone ignores the specifics that *are* there... :) 17:46
ruoso diakopter, it's not that it is specific... it's you that didn't reach the nirvana to get the abstraction yet ;)
diakopter exactly. my Bible-parser isn't yet single-pass.
ruoso TimToady, while you're around... 17:47
does submethods belong to the package or to the class?
diakopter tuit alert
ruoso that meaning... is it possible to invoke a submethod as a subroutine, passing the invocant explicitly (or not)? 17:49
pugs_svnbot r20666 | moritz++ | [spec] unfudged one passing test in exp.t
ruoso and if so, what happens when no invocant is given?
TimToady it's possible to invoke *any* method as a subroutine, if you turn it into a Code ref first
that's how dispatchers work
ruoso no... I mean directly by name 17:50
TimToady the magic of submethods is in the dispatcher
ruoso from that I would presume it belongs to the class, and that it would be part of the dispatch before falling back to sub dispatch
TimToady offhand, I don't think so
and I'm not sure we even need fallback from single dispatch to multiple dispatch, now that we have "is export" 17:51
(thought that's kind of intended for the opposite case...) 17:52
ruoso I didn't ever thought on having it separated... heh... I always thought it would behave as multi always, it would only stop looking it it knew that there were no variants
TimToady foo($x) is always a request for multiple dispatch, and $x.foo() is always a request for single dispatch 17:53
and cases like close($fh) vs $fh.close are now handled by "is export" 17:54
17:54 orafu left
b_jonas oh, so the one-argument named function exception is now gone? 17:54
lemme check
TimToady long time now 17:55
b_jonas ok, it would be difficult to check anyway for I've no idea which S to look
TimToady that's one of those durn specifics we got rid of
b_jonas 6 or 12 or 13
moritz_ b_jonas: exactly, one of these ;)
diakopter moritz_: how about making evalbot commands (and responses?) appear as C<> on the irc log :D 17:56
or just bold or something
moritz_ diakopter: do you mean enclosed in C<...>? or type writer?
it's all monospace at them moment 17:57
diakopter I don't know. just something to distinguish it as computer-readable as well as human-readable.
moritz_ diakopter: it's computer readable in the sense that everything from exp_evalbot is output from an eval command 17:58
are you planning anything special with the stuff?
TimToady afk & # シャワー
diakopter no, I just think it would be nice to be able to look at the irclog as a REPL log 17:59
moritz_ diakopter: maybe it's easier if I make evalbot log its in- and output somewhere?
17:59 renormalist left

diakopter I'm sure Auzon would love that... a hundred new test cases a day to sort into t/spec/
"hmm, what's this supposed to test?" 18:02
moritz_ but you can't automate it, and formatting is crappy
Auzon It'd be neat to harness evalbot that way. But it'd be hard to get useful stuff from just trying to get a syntax working 18:03

TimToady pmichaud: I think we probably need both names so that xyz() works as a function call, though I can think of ways to fudge it in the compiler. but if it's going to hide sub xyz anyway, why not clobber the name? 18:41
but I don't feel very strongly about it one way or the other 18:42
PerlJam what happens when xyz is a multi?
diakopter TimToady: the above trace output is with stmt merged into expr 18:43
TimToady I think multiness is orthogonal to how it's parsed
the only real difference is how you parse xyz 1,2 18:44
on the other hand, I think I see what you're asking 18:45
are prefix:<xyz> and sub xyz multis intermixed?
pmichaud partially.
I'm thinking of prefix:<abs> and $foo.abs
but yes, the question of multis is also there. 18:46
PerlJam In my head prefix: subs and "regular" subs live in different places because their long names are different.
Kind of like $foo and @foo (because the sigil is part of the long name) 18:47

pmichaud fser: it's not (yet?) part of the spec, but some implementations are providing one.

fser wow I guess I'm not aware enough about perl 6, you're speaking about multiple implementations .. 18:50

pmichaud Auzon: S29 doesn't have an 'atan' ? 21:07
Auzon "where func is one of: sin, cos, tan, asin, acos, atan, sec, cosec, cotan, asec, acosec, acotan, sinh, cosh, tanh, asinh, acosh, atanh, sech, cosech, cotanh, asech, acosech, acotanh."
moritz_ Auzon: don't rely on evalbot's UTF8 handling, it's mostly b0rked
rakudo_svn r28118 | jonathan++ | [rakudo] Make us able to use role names as type constraints again. We may have to revisit whether we want to register a Role proto at some point in the future; this gets things fixed for now.
pmichaud Auzon: I don't see that statement in S29
is it somewhere else? 21:08
Auzon acks
371:sin, cos, tan, asin, acos, atan, sec, cosec, cotan, asec, acosec,
in Pugs/blib/lib/Perl6/Spec/Functions.pod
pmichaud okay, got it. Thanks. 21:09
Don't know why my search didn't uncover it before.
Auzon No problem.
It appears that the test mistakenly puts atan instead of atan2 in some cases
I assume that we're keeping atan2 instead of having a 2-arg form of atan to handle the atan2 functionality, right? 21:14
moritz_ Functions.pod 21:17
393:=item atan2
pmichaud I can't tell for sure what's intend. I'm guessing that the "where func is one of: ..., atan, ..." might have intended to use atan2 instead
moritz_ ack (or grep) is your friend ;)
pmichaud since atan2 isn't in that list.
moritz_ pmichaud: it's an extra item in S29
pmichaud oh, okay. 21:18
so we have both atan and atan2
atan takes one argument like sin, cos, tan, asin, etc.
21:18 cjfields joined
moritz_ I think I asked that once already 21:18
atan2 has a default value for its second argument 21:19
so atan($x) isn't always the same as atan2($x)
Auzon Oh. OK
I missed that :)
moritz_ Auzon: that was more than a year ago
21:19 TJCRI left
Auzon I meant that difference in the spec 21:19
moritz_ (I don't know if my memory is correct, though) 21:20
pmichaud but is there a 2-argument form of C<atan> as in atan(1, 1) ?
(where the 2nd argument isn't supposed to be $base)
21:21 japhb joined
Auzon Not that I can see, pmichaud 21:21

moritz_ < TimToady> atan2 is still atan2 21:23
pmichaud excellent.
Auzon I'll fix up those tests and add some more for the one-arg version of atan2(). 21:24

moritz_ Auzon: I think calling is_approx like this: is_approx(($first, $second), $msg) is illegal 22:02
Auzon: many of the test still use that
Auzon looks at Test.pm 22:03
22:03 cjfields left
moritz_ because ($first, $second) is actually a list, that tries to bind to a single item in the signature 22:03
sub is_approx(Num $got, Num $expected, Str $desc?, :$todo, :$depends) returns Bool is export { 22:04

pmichaud I blame moritz_ . :-)
moritz_ pmichaud: moritz, not moritz_ ;-)
pmichaud I just tab-completed your nick. :-) 22:09
besides, I'll credit "moritz" and blame "moritz_" and you'll be much better off.
moritz_ lol
pmichaud when I was actively teaching courses, at the end of the semester we had "faculty evaluations" by the students. (more) 22:10
These were always done on scantron forms, where the student would bubble in things on a 1-5 scale. (more)
rakudo_svn r28124 | particle++ | [rakudo] improve eval_lives_ok and eval_dies_ok, courtesy of Ronald Schmidt <ronaldxs@software-path.com> 22:11
pmichaud I would always tell the studens to use ink for bad review and pencil for good ones, because I knew that our scantron reader didn't process ink properly, and they just discarded any evaluations that the scanner couldn't read.
22:11 jferrero left
moritz_ hehe, nice hack ;) 22:11
pugs_svnbot r20676 | moritz++ | [spec] S29-num/log.t fixed some ivalid calls to is_approx. 22:12
pmichaud (but then I would tell the students why ink and pencil made a difference, which pretty much invalidated it.)
besides, I never got bad reviews. (Although this past year may have changed that.) 22:13

moritz_ sorry, didn't mean to get in your way
Auzon No, it's OK, I was away
moritz_ is pi() exported by default? 22:25
trig.t tests for it without importing it first
22:26 cjfields joined
[particle] iirc yes 22:26
s29 i think?
22:26 cjfields left
moritz_ Num provides a number of constants in addition to the basic mathematical functions. To get these constants, you must request them: 22:26
use Num :constants;
or use the full name, e.g. Num::pi. 22:27
[particle] ok, that has changed
22:27 cjfields joined
moritz_ just found it 22:27
b_jonas what?
moritz_ goes to bed, too tired for useful hacking
b_jonas is there even an S that specifies _that_?
b_jonas checks out S29

b_jonas ah, it's S29 indeed 22:28
Auzon see you, moritz_. I won't be around much if at all tomorrow
