brahmam is perl6 interpreted or compiled 05:23
shachaf Languages aren't interpreted or compiled. 05:24
brahmam what is the end output.. i mean executable code... 05:26
i am very very new to perl
shachaf The end output of what?
brahmam like.. in java... the class file
shachaf Languages can be either interpreted or compiled, depending on whether you use an interpreter or a compiler. Perl 6 has both, as far as I know. 05:27
sorear All known implementations of Perl 6 have both an interpreter and a compiler.
brahmam do perl5 has compiler too..
sorear Yes.
brahmam so what is the executable file of perl script file.. 05:28
doy basically all non-toy languages have a compiler of some sort
brahmam sorry... doy.. i didn't get you... what do you mean by non-toy languages... you mean which are not something fo experts.. 05:29

brahmam one of my collegue said compiler based langs perform better than interpreter based.. 05:33
doy that depends entirely on the compiler and interpreter involved
brahmam i am basically a oracle DBA, i want to design a tool, something like sql*plus, which can connect to any db ie. oracle,mysql, db2 or SQL Server with same syntax you are comfortable with.. 05:34
05:34 telex left
doy i suggest trying out the languages you're interested in and seeing if they are fast enough 05:34
brahmam its basically converting the string entered by the user... to the equivalent of the target database, something lik ORM tools do.. 05:35
doy perl 5 can do something like that via SQL::Abstract
i'm not sure if perl 6 has something similar 05:36
brahmam as i am new to perl.... is it worth giving a shot at ...i want to take expert's advise.. 05:37

masak mornin', #perl6 09:20
FROGGS_: theoretically, alternations of the LTM could be done in different threads. but something tells me there's not such a big speed gain to be had in that. 09:21
because each alternation is fairly short, and would probably be dwarfed by threading overhead.
FROGGS_: no, the real benefit is that conceptually, a DFA doesn't "go back" and try the next alternation from the last branch point. instead, the DFA tries all alternations conceptually "at once". by the end, all the non-matching alternations have been eliminated. 09:23

wow, reading brahmam's question in the backlog is interesting.
I could easily see myself asking such a question a couple of years back. 09:27
especially the "a colleague said a compiler is faster than an interpreter, is it true?" question.
but from my current vantage point, it just feels like brahmam is asking from within a great fog, and the answers barely reach back in to him. 09:28
lichtkind: in github.com/perl6/tablets/commit/696f770d96 , why do you call it a "string object" when "string" is adequate? we don't talk of "integer objects" or "boolean objects" either. 09:31

Example of something that is easy in AWK and Perl 6, but hard in Perl 5.
masak oh, it's awk. 09:57
I was wondering what weird dialect of Perl that was :)
GlitchMr I've choosed Perl just for syntax highlighting.
In Perl 5 it looks simple: join ',', map quotemeta, @words... except that actually doesn't work 09:59
oops
join '|', map quotemeta, @words
masak nowadays I'm always suspicious of the practice of building sublanguages using strings. 10:00
not only because of the general risk of injection attacks, but because of the crudeness of the approach.
GlitchMr This is what PHP people do, I know. Oh, and Perl 5 with its regexpes. 10:01
Also, oops, my approach is simply wrong. It assumes array isn't empty.
It should be fixed now 10:04
tadzik ah, the ol' "interpreted vs compiled" debate... 10:05
doog morning #perl6 10:06
GlitchMr But... only UNIX shell language is popular interpreted language.
Other languages are compiled.
Perhaps they aren't compiling programs to files, but they still compile programs. 10:07
sorear GlitchMr: unix shell is actually pretty compiled
GlitchMr Why program like this is valid then: 10:08
exit
ds'gew;tewv tv'ewrr.c24'r32$C"#@R?X"#@>""~``"3c;xe@"#:ex'@
sorear because compilation occurs one line at a time
s/line/top-level statement/
wrap that program in an if true; then ... fi and it won't compile.
GlitchMr Well, ok, that program had valid syntax 10:09
But perhaps something involving $) or something. 10:10
exit
$)
In if true; then ... fi it isn't valid anymore 10:11
masak tadzik: it's silly. "compilation" is just a kind of translation. computers do it all the time. "interpretation" is just a switch statement in a loop. computers do that all the time too. 10:17
which one is faster? the question almost isn't well-posed.
GlitchMr Is Brainfuck interpreted or not (answer: depends on implementation)? 10:18
masak yes, and that's what people answered brahmam in the backlog. 10:20
sorear as someone who has spent a non-neglible amount of time studying CPU design, let me say that *everything* is interpreted... 10:22
masak aye. 10:23
sorear besides, transistors are a physics-based system for interpreting Boolean algebra. and some people say even physics is an interpreter...
masak is struck by how the Church booleans look a bit like abstract transistors 10:25

jnthn morning o/ 10:33
sorear o/ jnthn 10:34
jnthn An interpreter is just something that processes instructions and takes actions based on them. If the input to the process is different from the thing that gets interpreted, then there's a compiler inbetween the two performing that translation.
masak jnthn! \o/
tadzik there's no one to convince anymore :)
jnthn Aye, just thought that was a nice way of putting it :)
masak aye. 10:35
lizmat which would make perl* a compiler? 10:38
jnthn lizmat: Sure, it doesn't work directly off the source code, but instead interprets a tree structure. 10:40
moritz well, perl 5 contains both a compiler and an interpreter
jnthn Right.
moritz as does Rakudo
lizmat indeed… so it's getting foggier and foggier, no?
who cares anyway… :-)
as sorear pointed out, it's all interpreted by the CPU anyway :-) 10:41
moritz right, it's all a continuum these days
jnthn I suspect people are more inclined to believe things are compilers when they feed source code in and get some other file containing some other form of the program out.

moritz I guess we will uncover several missing pieces 11:41
one I know about is

p6eval rakudo 53daef: OUTPUT«␤␤␤␤␤ok␤»
moritz r: my $x = 0; while $x++ < 5 { for 1 { .say } }; say 'ok'
p6eval rakudo 53daef: OUTPUT«1␤1␤1␤1␤1␤ok␤»
moritz that one only prints the last 1\n currently 11:42
I guess that needs modification to the codegen of loops
r: my $x = 0; while True { last if $x++ > 2; $x } 11:43
p6eval rakudo 53daef: ( no output )
moritz r: my $x = 0; say do while True { last if $x++ > 2; $x }
p6eval rakudo 53daef: OUTPUT«True␤»
moritz oh, the return value is the condition?
then I guess the block just needs to be sunk always
r: my $x = 0; say do while $x++ < 5 { 1 } 11:45
p6eval rakudo 53daef: OUTPUT«False␤»
dalek kudo/qast-sink-1: f122e60 | jnthn++ | src/Perl6/Actions.pm:
Sink 'handle'.
moritz 'handle' handles exceptions?
jnthn Yeah 11:47
That got us back a couple of tests
ah
I see why the keybag ones explode.
It does something like sub choose { ... for @blah -> $m { if ... { return $m } else { ... } } } 11:48
And now that for is not eagerly evaluated, the return can happen too late
moritz r: eager for ^5 { .say } 11:50

iteration. Each iteration's value is returned as a single "argument" 12:30
object. See L<S02> for a long definition of argument, but in short,
it's either an ordinary object or a parcel containing multiple values.
There's not a single spectest match for do while/do repeat/do until/do loop. 12:32
moritz hrmpf 12:33
I can see how that is consistent with for loops, but I don't know how useful it is 12:34
jnthn Either way, it doesn't change that the loop body should be in sink context.
moritz erm 12:35
jnthn er, wait
moritz if the values are collected, they aren't in sink context
jnthn Right
moritz unless the loop itself is in sink context

just discussing ovid's use of B::Deparse for his Perl 5 code deduplication module that he's working on

jnthn In Perl 6 we should probably be building such things at the AST level. 13:09
moritz: ooh, eek 13:10
moritz: When we sink "try", we sink the exception that gets caught in the catchless case, it seems

moritz only 14 test files failing in qast-sink-1, jnthn++ 16:02
Woodi is something like "partial evaluation" en.wikipedia.org/wiki/Partial_evaluation considered in Perl6 ? 16:13
moritz I guess I know the reason for most of the failures in the sink branch 16:18
nested loops aren't executed the way you'd expect them to
./perl6 -e 'for ^2 { .say; for <a b> { .say } }
0 1 a b a b

skids Woodi: I would suspect it is on many levels. It's a rather broad concept. 16:21
jnthn moritz: oooh. Hm. 16:22
16:22 MayDaniel left
jnthn That is a bit of an issue if you're evaluating the things for their side-effects... 16:22
Woodi I just wonder if binary for four operation calculator with console IO still contains hashes, evals, methods... 16:23

Woodi n: my $bar; say $bar 16:26
p6eval niecza v24-5-g599cbcb: OUTPUT«Any()␤»
Woodi shouldn't it say empty string ?
jnthn No 16:27
lizmat my understanding is that "our" is lexically scoped, even though it is referring to a package variable
our is that too perl5ish?
s/our/or/ 16:28
jnthn lizmat: our gives you a lexically scoped alias to a package-scoped variable.
our $bar # like my $bar := OUR::<$bar> 16:29
lizmat ah, so you're saying the our inside the sub is an alias to the same package var outside
and so that rakudo *is* wrong in this example... 16:30
ok, gotcha 16:32
jnthn lizmat: Um, I didn't say Rakudo was wrong. 16:33
They're both aliases to the same thing in the package.
Thus "alias" :)
Really it's just binding. 16:34
lizmat but the assignment in foo() should be visible outside, no?
jnthn Oh...I misread the output
Then I guess Rakudo gets it wrong
Which isn't so surprising since it doesn't even try to make our @foo and our %bar work... 16:35
lizmat ah, ok
jnthn One of those "nobody really seems to care about it so much as they care about other things so it never makes the top of the todo list" things :)

jnthn lue: No.
That's the point of them.
We use them to implement stuff like inheritance. 22:10
lue Didn't seem like it from my glance at them yesterday.
(your answer to my question, that is)
jnthn I'm a bit surprised that the attributes they have aren't just conveyed to the target class and the fixing up happens there
Oh, but maybe it's not set up that way... 22:11
lue (fwiw I had yet to apply the Children role to any classes. I wanted to see if what I did so far would compile.)
jnthn If you add something to the role implementation then really it just needs to play pass the parcel. 22:13
That is, it doesn't actually set any mappings up
It just passing them along to the class
That's done by the applier
It may not be too hard to figure out how to do that. 22:14
