dduncan opinion question: what's a good name for a fundamental quasi-function that is used for arbitrary expression validation, where it returns its primary argument if its secondary argument is true, and it throws an exception if its secondary argument is false? This would be used in a pure functional context, throwing an exception aside 00:19
eg, say it was called 'gate', it could be invoked using gate( $x, $x != 0 ) 00:21
but I was looking for a name that wasn't a verb but a noun
alternates could be 'expected' or such 00:22
or nevermind, I"ll just pick something and maybe change it later

TimToady @tell pmurias those variables are an intrinsic part of any block's lexpad, so must be created as soon as the lexpad is created, but just after the signature has added its lexicals, in case the signature has already inserted one of those variables (typically $_) 16:01

17:37 rdice left
pmichaud I think that the block to a C<if> is an immediate block, so it doesn't localize $_ 17:42
17:42 justatheory left
pmurias pmichaud: only none immediate blocks do? 17:43
or doesn't -> {} do initialization to?
pmichaud I think -> {} gets a local $_
and takes no arguments 17:44
TimToady the block is really -> $_ = OUTER::<$_> {...}, and since if doesn't pass a param, it is bound to the outer $_
pmichaud ...bound or copied?
TimToady bound
or it doesn't work right
pmichaud right
so $_ = OUTER::<$_> also has an (implicit?) is rw
TimToady yes 17:45
parameters are for binding, so defaults are bound as well, despite the appearance of = 17:46
pmichaud right
except for something like is copy, I suspect
TimToady which is why we often call it pseudo-assignment
pmurias pugs: $_ = 8;my $code = -> {$_ = 5};$code.();say $_;
p6eval pugs: OUTPUT[5␤]
TimToady well, one of the reasons...
arguably wrong there, since -> implies a () sig 17:47
pmichaud pugs: $_ = 8;my $code = -> {$_ = 5};$code.(1);say $_; 17:48
p6eval pugs: OUTPUT[*** No compatible multi variant found: "$code"␤ at /tmp/jEdp1dyJUX line 1, column 31-40␤]
TimToady but pugs may be treating -> {...} as equivalent to {...}
pmichaud so, in the -> { ... } case, the $_ should not be bound to the outer $_
(which is as I remember it)
TimToady I would think not.
pmichaud okay, thanks. 17:49
pmurias TimToady: thanks for the clarification 17:50

TimToady: I've been thinking of Latin, Greek, German or something.
TimToady: and I need to keep up with my Written Arabic. 18:52
Written Arabic is beautiful but often counter-intuitive.
and no longer actively spoken.
My friend has a theory that in 50 years Hebrew will be the Lingua Franca of the middle east.
Not Arabic. 18:53
TimToady Japanese has the advantage of teaching you to think in reverse polish
rindolf TimToady: heh.
TimToady: I wonder if Aristotle' Prior Analytics is any less opaque in the original Greek.
Or his Metaphysics. 18:54
TimToady depends on whether you speak original Greek I imagine :)
rindolf TimToady: ancient Greek.
Greek evolved quite a bit.
TimToady that too

TimToady: I think Pugs was a mistake. 19:06
They spent too much effort on an implementation in a bad language.
TimToady you're entitled to your opinion, but every effort has taught us many things
rindolf TimToady: right.
TimToady and not just how not to do it 19:07
we have a test suite right now because of pugs
rindolf TimToady: ah.
Which Pugs fail some of the tests of it.
TimToady we now understand the synopses in much greater detail because of pugs
programming in Haskell forced us to answer some very important questions that would otherwise have never been asked 19:08
because Haskell don't stand for no nonsense... :)
rindolf I suppose 1 bird in the hand is better than 2 in the tree.
<TimToady> because Haskell don't stand for no nonsense... :) - pardon?
TimToady 1 bird in the hand *and* 2 in the tree beats the *or* version 19:09

TimToady so basically, thinking that pugs was a mistake is a mistake 19:11

Auzon What context does cmp use in this case? 20:03
20:03 dolmen joined
rindolf TimToady: do you have an RSS reader? 20:03
Maybe say is an operator.
Auzon: ^^^
pmichaud say is a function.
rindolf pmichaud: ah.
pmichaud: but in perl 5 all built-ins are operators.
Well, they have prototypes.
Auzon rindolf: In Perl 6, all operators are functions.
rindolf Auzon: ah, cool.
I figured so.
pmichaud (but not all functions are operators :-)
Auzon just with funny names like infix:<~>
rindolf Auzon: but they have precedence.
Auzon re precedence, yes, but so do functions. :) 20:04
rindolf Auzon: ah, nice. 20:06
Auzon: did you figure out how macros are going to change the grammar on the fly?
Would it be something like Scheme's hygienic macros?
The (define-syntax stuff?
Auzon rindolf: I haven't investigated it beyond a brief look at S02's quoting section
20:06 pmurias joined
Auzon rindolf: Have you seen my factorial operator example? 20:07
rindolf I have yet to read that featured LtU article about Scheme's macro systems.
But I want to.
vixey every macro system goes in define-syntax
rindolf Auzon: I cna understand CL's and Arc's (defmacro Or (mac but they kinda suck. 20:08
vixey there's some hygienic and some non-hygienic
defmacro is good in CL since you have multiple namespace, but that approach is not useful in scheme (with a single namespace)
(except in rare circumstances)
20:09 jhorwitz left
rindolf vixey: ah. :S 20:09
vixey: CL's namespaces kinda suck.
I prefer Perl's
vixey no they don't 20:10
rindolf Which are nested.
Well, they are flat.
vixey: BTW, I'm renaming Park to Spark and continuing to design it.
And I'll probably start working on a Parrot implemetnation.
Auzon apparently my factorial example no longer works in Pugs here. :-/
rindolf It will be a Random-Tweakers project. 20:11
20:11 rodi left
rindolf Auzon: bitrot! 20:11
Auzon Presumably so, since p6eval's environment was upgraded, and maybe Pugs was recompiled
rindolf Auzon: hmmm... 20:12
Auzon: isn't it pure-p6?
Auzon Pugs, no. Pugs is significantly Haskell
pmurias rindolf: what is Park/Spark?
Auzon anyway, here's my example: multi postfix:<!> (Int $a) {[*] 1 .. $a}; say 6!;
rindolf pmurias: www.shlomifish.org/open-source/proj...Park-Lisp/ 20:14
lambdabot Title: Documentation for the Park Lisp Dialect
rindolf pmurias: it's still incomplete.
And I haven't updated it.
Auzon: why does it have to be a multi-method?
Auzon It doesn't, but it allows another one to be declared for another signature 20:15
pmurias rindolf: if you like lisp/perl6 projects you might consider helping with a common lisp elf backend 20:16
rindolf pmurias: Common Lisp. 20:18
pmurias: thing is I think both CL and Scheme suck.
I like Lisp as a concept.
Arc is nice, but has too many implementation problems.
And missing features.
vixey Arc is not nice 20:19
rindolf I want to give a presentation to the Perl Mongers about "Foreign Languages: Lisp"
vixey: I like it.
Though I hate that "(not)" has become "(no)"
it's so non-English.
vixey it's just TCL with horrible syntax
rindolf vixey: but it's missing a lot of exciting features. 20:20
pugs_svnbot r21083 | pmurias++ | [pixie] support for keeping arbitrary stuff inside {*} blocks and storing in in an external (to STD) filenot yet used/properly tested but i'm comiting as i rm it once before ;)
rindolf Which PG deemed (sp?) as unnecessary.
Doesn't look like the 100-years language to me.
Which is why - Spark!
pbuetow hmm. 20:21
pmurias why not just write an s-expression p6 dialect?
rindolf pmurias: could be. 20:22
pmurias: it's another approach.
But some things make sense in Lisp and not in p6.
For example, Perl does not like to use + for string or list concat.
While Python does and it seems to be OK in Arc too. 20:23
And in CL you have (concatenate) (yuck!).
pbuetow (((hehe)))
pmurias + for strings sucks 20:24
Auzon seconded.
vixey rindolf: If you don't like CONCATENATE you can just rename it
rindolf vixey: yeah. 20:25
20:32 vixey left, vixey joined
rindolf vixey: but I'd rather not rename concatenate because then people won't understand my code. 20:35
vixey: as TimToady said people hate abstractions.
vixey yes they will rindolf
rindolf They want things to work out of the box. 20:36
vixey A program is many many totally newly defined procedures
just renaming one thing is nothing in the context if a big program
rindolf vixey: "let's spend 3 days creating a new language, and 1 day implementing the solution with it." 20:37
TimToady if it would take 10 days without the new language, it's worth it 20:39
rindolf TimToady: yeah.
TimToady: but this is the CL mentality.
vixey no it's not
rindolf Sometimes you can take 1 day to write an API.
vixey CL is too diverse you cannot generalize like that
rindolf vixey: I meant a common idiom there. 20:40
I think I'll /quit and do something productive.
Like work on Spark.

In the Internet banning, kicking, etc. someone is so effortless so people abuse it too much. 20:47
I hate it when people say "Spam" to something low-quality, or flamatory.
Or that they refer to banning someone as kicking.
pmurias kicking people in real life definitly requires more effort 20:48
rindolf www.google.com/search?hl=en&c2c...tnG=Search - WTF?
pmurias: well, kicking on IRC is not like kicking IRL. 20:49
pmichaud okay, I'm a little confused again. I'm trying to get rid of a rakudo cheat but I'm missing an important piece
rindolf You can tell this person to shut up.
TimToady isnt that what a /kick means? :)
pmichaud if we have "my @b = (4,5)" and "my $b = (4,5)", both @b and $b have type Array
but push @foo, @b and push @foo, $b have different results 20:50
TimToady yes, well $b is technically Scalar of Array, i suppose
pmichaud ok, so $b is Scalar of Array
TimToady Scalars stay scalar in list context 20:51

pmichaud that's what gets returned by the various comparison ops
Auzon Order::Increase, Order::Same, Order::Decrease numify to -1, 0, 1 in that order 21:25

pmichaud 'a' gt 'b' returns Order::Increase 21:25
dolmen ok
pmichaud sorry, 'a' cmp 'b' returns ...

yeah
pmichaud right, wrong op :-)
I may just cheat Order:: for now :-) 21:26
21:26 TJCRI left
pmichaud otherwise we fail the spectest_regressions ... 21:26
Auzon I don't know what they need to do other than numify properly 21:27
pmichaud I _really_ wish we had automatic email of changes to pugs svn repo. 21:28
dolmen they have to perl-ify properly too
pmichaud it would be much easier to keep track of changes
(to the spec tests) 21:29
otherwise I start getting spectest_regression failures and I have to go track it down.
dolmen I have created S02-builtin_data_types/range yesterday and it fails 21:32
pmichaud it may be fixed soon :-)
the one I'm having trouble with at the moment is S04-declarations/multiple.t 21:33
I'm getting a failure and I don't know if it's because the test changed or if it's something I did.
(but please don't take this as an indication that I don't want the test files to change.. I'll gladly hunt down changes if it means the test suite is improving, which it is) 21:34
(I just wish pugs svn was sending me email notifications about it :-)
dolmen how do you get verbose output of tests? 21:35
'make localtest' is too quiet
pmichaud there's not a really good way to do it. 21:36
dolmen It doesn't say which test failed
pmichaud normally I just run them directly
Auzon Same here 21:37
pmichaud (doesn't say which test failed) depends on what version of T::H you have.
(Test::Harness)
on my system it tells me which tests failed
Auzon If I'm testing fudge, I'll do something like: ../../parrot perl6.pbc `fudge blah blah`
pmichaud I typically do ./parrot perl6.pbc t/spec/S00-whatever/foo.t
or
./parrot perl6.pbc t/spec/S00-whatever/foo.rakudo 21:38
dolmen you mean 'parrot perl6.pbc t/spec/...
?
:)
pmichaud yes, but I'll choose the .t or .rakudo test as appropriate
(the .rakudo version of the is the fudged version) 21:39
*of the test is ....

Auzon was not aware that {my $x; my $x} was legal 21:52
21:53 alester left
TimToady yes, what you cannot do is { $x; my $x } since the first $x is bound to an outer $x 21:56
Auzon so sub foo ($x) {my $x} is invalid?
TimToady perhaps only because the signature's declaration of the lexical is readonly, which conflicts 21:57
note that the compiler is allowed to warn about {my $x; my $x} unless you say proto $x up front. 22:00
but it's just a warning, and both $x's are the same $x 22:01
so we don't have to figure out scopes of the form "here to the end of the block"
Auzon Yeah, makes sense 22:02
TimToady especially when looking up the dynamic stack
and since {$x; my $x} presumably captures a link from $x to $OUTER::$x on the first $x, we can note the collision 22:03
