R0b0t1 If I were to compare perl5 and perl6 to say, python2 and python3, how wrong would I be? 07:02
07:02 virtualsue joined 07:03 dmol joined
xiaomiao R0b0t1: green 07:04
brrt it would be wrong in the sense that python3 is supposed to be python2 cleaned
and perl6 maybe was supposed to be that once, but its now a thing of its own
R0b0t1 What do yo- oh right.
brrt iirc perl6 is meant to be the language that programmers will use a hundred years from now
R0b0t1 brrt: I see. So what did it implement that isn't merely "cleaning?" 07:05
07:05 sftp left
R0b0t1 My, what lofty goals. 07:05
brrt ok, to compare, python 3 cleaned: metaclasses and unicode
iirc
perl6 changed syntax, object system, meta-object system, string encoding, i.e. the whole works 07:06
i think the right way to compare perl5 and perl6 is perhaps middle english and modern english?
most of the same structures are superficially there, but most of what you'd count as 'fundamental' has changed 07:07
07:07 woolfy1 left, lizmat left
R0b0t1 Well some of those things sound like internals... that'd be more like changing the alphabet perhaps? 07:08

08:07 ChoHag joined
ChoHag I have the code at gist.github.com/anonymous/1fab6c3c028192d89b31 to define a trait on an attribute. It uses apply_handles to create a wrapper around the attribute's accessor. 08:08
Line 22 fails with Cannot modify an immutable Any (or Str etc., if x is defined at foo.new time) 08:09
Ven actually remembers that "but" is immutable and "does" is mutable because "shorter is better". eh ...
ChoHag Ah but works. 08:10
I remember skimming over the explanation of the difference.
Ven `but` gives back a copy. `does` modifies it in place, destructively

ChoHag What does -> do? 17:07
And (where) is it documented?
TimToady lambda
17:07 SamuraiJack joined
timotimo "->" <signature> <block> 17:08
ChoHag How does that compare to sub <signature> <block>?
timotimo you mean "sub <name> <signature> <block>"?
ChoHag Ah right.
TimToady S06:Point_blocks
timotimo m: sub ($a, $b) { say $a }
camelia ( no output )
timotimo ah, that does work 17:09
TimToady S06:Pointy_blocks
ChoHag But:
m: sub ($a, $b) { say $a }.(1,2)
camelia rakudo-moar a7b4cb: OUTPUT«1␤»
TimToady it's much like an anonymous sub, but return won't work
because Blocks are transparent to return 17:10
timotimo ah, right
that's a good point
17:10 uniejo joined
ChoHag Right, so they're (-> and sub) essentially the same without the layer of scope which would catch the return? 17:11
17:11 uniejo left
TimToady that's the main difference you'll ee 17:11
*see
technically, blocks are immutable, and routines aren't
so you can .wrap a routine, but you can't .wrap a block
17:12 Alina-malina left
TimToady of course, if you have a container, you can make it look mutable, as we do with string vars. 17:12
17:12 Alina-malina joined 17:13 pecastro left, jnap left
ChoHag How can I .wrap a routine without affecting the mutability of the result of callsame/callwith? 17:14
17:16 uniejo joined
ChoHag I have $pkg.HOW.find_method($pkg, $accessor).wrap($routine) which I want to call the original accessor and fiddle with the result (and, if I can, the value going in). 17:16
17:16 Alina-malina left
TimToady generally you need to work with | and \ to keep things in terms of Captures and Parcels 17:17
don't use sigils for the intermediates
ChoHag Actually right now there isn't an intermediate.
17:17 Alina-malina joined
TimToady and the wrapper might need to be declared 'is rw' as well 17:17
I doubt wrapping copies that for you. 17:18
ChoHag essentially: find_method(...).wrap({say "in accessor"; callsame})
How do I do that? I have the wrapper in a variable but it wasn't just "$r is rw" :(
TimToady sub (|) is rw { say "in accessor"; nextsame }
if that's all you want to do 17:19
you don't have to return to here with callsame unless you want to postprocess the args
s/args/returns/
ChoHag What does that mean "return to here"? 17:20
timotimo "callsame" acts like a call
"nextsame" acts like a goto
ChoHag Ah. 17:21
Right. Hence the s/// which I ignored.

smls rant of the day: Why does the syntax for inline comments have to be so strange? 17:51
17:51 SamuraiJack__ joined 17:52 uniejo joined
smls Removing the backtick would be an improvement: #( bla bla ) 17:53
Wouldn't that work?
TimToady used to be, but it's problematic if you take a block and put # in front of each line
you don't want end-of-line comments accidentally turning into nested 17:54
FROGGS_ I somehow like #* ... *#
but I do not write comments anyway :P 17:55
I mean, it is source code after all :o)
17:55 SamuraiJack_ left
smls TimToady: Maybe it could be restricted to one type of brackets then? 17:57
So no curly braces (which would probably cause the most trouble) 17:58
TimToady other DSLs could have different issues
and we're optimizing for extensibility 17:59
and comments ought to stand out visually
smls Personally, I tend to always edit code in an editor with syntax highlighting, and for commenting whole lines/blocks I use an editor shortcur which does the right thing
TimToady you can make a slang with your own commenting scheme :) 18:00
vendethiel how do slangs interact with macros ?
18:00 SamuraiJack joined
masak very well ;) 18:00
TimToady a macro is basically a mini-slang 18:01
vendethiel masak: BZZT! wrong answer
masak macros are just routines.
18:02 itz joined
TimToady macros are like an elephant 18:02
masak if you can call them from your slang, you can interact with it.

vendethiel everytime I see nested stuff in perl 5, I go like "how do you remember that?". But I probably do the same all the time 18:08
18:08 kaleem left
masak "nested stuff"? 18:09
18:10 uniejo joined
FROGGS_ interpolated stuff in quotes or regexes I guess 18:10
vendethiel masak: $a[0]->[0] or $a->[0][0] or $a[0][0] ?
FROGGS_ ahh 18:11
18:12 rurban joined 18:14 btyler joined
masak oh, that. 18:14
yeah. I can do it... but I prrefer not to :)
smls 1) sticking two postcircumfixes together is syntactic sugar for an arrow between them (so if you see [0][0], imaging [0]->[0]) 18:15
2) arrows dereference
^^ really all you need to remember
vendethiel "dereference" ?
Well, I'll learn about it with the book woolfy++ gave me at some point. 18:16
FROGGS_ yes, the array derefs
vendethiel I just don't really, uh, carry it out a lot; because it's heavy.
FROGGS_ $a[0] in P5 is about a variable @a
smls take a reference (which is a scalar value), and return the value that it points at (which can be any kind of scalr/array/hash/object)
vendethiel FROGGS_: that I know :)
FROGGS_ $a->[0] is about a variable $a that is an array reference

smls TimToady: You know what would be cool? Allow matching a grammar/regex against a *list* of strings, and have a syntax for "match a string boundary here" anchors inside the grammar 18:30
18:31 matija left 18:32 Sqirrel joined
masak don't the ^ and $ anchors already match a "string boundary"? 18:32
18:33 rurban joined
masak seems to me the only missing piece is the ability to keep matching after that. 18:33
smls In Perl, I sometimes concatenate multiple strings with null-bytes, and then use a regex on the combined string (to leverage the power of the backtracking engine to solve my multi-string comparison/matching/selection problems for me) 18:34
vendethiel uh.
smls but that feels dirty, is not always safe, and will probably not work in P6 (where strings are more hihg-level)
The second solution at rosettacode.org/wiki/Find_common_di..._path#Perl (which I added today) is one example 18:36
another use-case would the the parsing of command-line arguments which I talked about a while ago
(since those already come in partially pre-tokenized)

PerlJam smls: what do you mean by "transparently"? 19:35
(because I'm pretty sure they're going to need to see each other to make that work :)
smls so you can refer to <foo> as if you had defined «token foo { ... }» in the same grammar 19:36

emilper I am attempting to use libgsl (GNU GSL) with NativeCall, but libgsl it misses a function from libcblas, and libgsl is not linked with libcblas at all supposedly so executables using libgsl could link with alternatives ... what options do I have ?

PerlJam I'm not sure when it actually does the dlopen() 20:15

Since it will loadlib on the first call
PerlJam gotcha

vendethiel I'd do my test locally but I'm on 2014.03. Guess I'll whisper camelia 20:48
TimToady .[] is a no-op
whereas .[*] is a slice 20:49
vendethiel and, yeah, seems like [1, 2, 3] interpolates quite seamlessly in a string. Not sure WDYM lizmat?
timotimo i thought .[] is like .list?
TimToady and a normal slice returns everything *except* the array
well, yes, it's like .list

I mean, if you do start { loop { } } a bunch of times, for example, you exhaust the thread pool 20:56

vendethiel yeah, alright; but what about arrays ?
smls Consistency, i guess. And [] is easier to type for interpolation. 20:58
vendethiel i still mean [*], not []
I get that [] is useful for interpolation -- it indeed is :)
