It's beautiful. | |||

szabgab | oh I see | ||
ironcamel1 | i keep 2 clients running for error checking/debugging etc | ||
szabgab | I have enough errors in one client :-) | 05:17 | |
ironcamel1 | szabgab, one suggestion for your website is don't make users have to register to leave a comment. just my opinion. | 05:18 | |
szabgab | anyway we still have to see if the Perl 6 regexes are going to become ugly because of the extensive escaping or not | ||
ironcamel1 | well, of course they will be | ||
they will be full of backslashes everywhere | 05:19 | ||
szabgab | regarding the comment system, if that can be done with the disqus thhing then I can try to do that | ||
ironcamel1 | unless you can do something clever with the literal q{} strings in the regexes | ||

Matt-W | Morning | 07:07 | |
sjohnson | hello | ||
moritz_ | oh hai | 07:08 | |
sjohnson | does anyone here hate programming in Javascript, PHP, CSS, and HTML all in one? | 07:10 | |
Su-Shee | sjohnson: I don't besides PHP. | ||
moritz_ | sjohnson: yes ;-) | ||
Su-Shee | actually, I really like the combi js, css and html/xul :) | 07:11 | |
07:11
synthEEEE joined
|
|||
sjohnson | moritz_: me too | 07:11 | |
i think i'm gonna have to quit my job | |||
this is getting far too boring and painstaking | |||
Su-Shee | sjohnson: you forgot the additional window with the database/sql stuff. ;) | 07:12 | |
sjohnson | yes, i did forget that :) | 07:13 | |
i become very happy programming Perl scripts at work to do routine things | |||
i almost jump at the opportunity | 07:14 | ||
contrasted with the unbelievable pain of coding in PHP | |||
... PHP and friends, i mean | |||
Su-Shee | sjohnson: until today I managed to avoid to get any php job but the one I've tried once and hated. | ||
sjohnson | Su-Shee: this may seem like a no brainer, but you like Perl, right? | 07:15 | |
Su-Shee | sjohnson: totally. | ||
sjohnson | me too | 07:16 | |
Su-Shee | sjohnson: I had a perl crisis a few years ago and let myself be seduced by python and a little ruby, but went back. | 07:17 | |
sjohnson | please tell me how that went | ||
as i also had a crisis | |||
but came back once i found that Perl 6 does all that Perl 5 didn't do | |||
jeekobu | I'm in the middle of such a crisis I guess | 07:18 | |
For my research scripts anyway. Python has easy memoization and built-in big int support, P5 doesn't | |||
Su-Shee | well, from the outside it looked like perl wouldn't make it into more contemporary programming, so I checked other things out. then came a) perl6 and b) cool new shiny things in perl5 and I jumped back immediately. | ||
sjohnson | jeekobu: do you know if Perl 6 can handle it? | 07:19 | |
Su-Shee | jeekobu: check higher order perl, there's plenty about memoization. | ||
sjohnson | Su-Shee: i checked out ruby too | ||
i think David Flanagan's book is confusing as hell | |||
obviously will get 5 stars on amazon, but an example of the worst kind of technical manual i have ever read | |||
the Camel book is so much nicer | |||
and a hell of a lot funnier to read | |||
Su-Shee | sjohnson: it's mostly that I read many amazing details about perl 5 (like HOP) which convinced me even more. I got in touch with perl's sexiness again. | ||
07:20
donaldh left
|
|||
Su-Shee | sjohnson: and if you check out projects like moose for example - it's a-ma-zing how flexible perl is. | 07:20 | |
jeekobu | sjohnson: You mean the current implementations? I don't know | ||
07:20
donaldh joined
|
|||
jeekobu | sjohnson: Sort of why I drifted back to checking out P6; it's been a few years | 07:20 | |
Su-Shee | sjohnson: and there's nothing like CPAN. | ||
jeekobu | sjohnson: OTOH I'm vary wary of jumping on a still-rapidly-evolving platform. That's been a huge part of Python's problem. (And various other software platforms.) | 07:21 | |
sjohnson | righto | 07:22 | |
my biggest gripe in Perl 5 is no trim function | |||
Su-Shee | trim? | ||
07:22
synth left
|
|||
bionoid | sjohnson: for real? it's like a 0,2 liner | 07:22 | |
Su-Shee | *hihi* 0.2 liner :)) | 07:23 | |

dakkar joined
|
|||
sjohnson | yeah, having to reinvent the wheel for the 50 perl scripts i have that use it | 07:23 | |
gets annoying fast | |||
Matt-W | yeah that bugs me too | ||
It's so common it just feels like it should be a builtin | |||
sjohnson | Matt-W, i couldn't agree more | 07:24 | |
having to refine my own trim function every single time i write a script that uses it, or install String::Strip with CPAN... | |||
on every system I migrate to.. | 07:25 | ||
moritz_ | maybe you could sneak it into Scalar::Util, which is a core module? | ||
sjohnson | i would like to, but how sneaky would i have to be? | ||
i want to do whatever it takes to get it backported into Perl 5 | |||
i could live with a core module | 07:26 | ||
moritz_ | no idea really | ||
sjohnson | until Perl 6 comes out | ||
Su-Shee | (oooh, please let me get the job where the ceo says "oh, yes, let's have an eye on perl 6, we're commited to use perl the next decade..") | 07:27 | |
sjohnson | moritz_: maybe i could get in touch with the Core Module author? | ||
i convinced the ANSIColor author to inclide a stripColors function | 07:28 | ||
so maybe it might be all that is needed | |||
include* | |||
moritz_ | Su-Shee: when will that be decided? | ||
sjohnson: it's dual lived, so you'll find the author by a quick CPAN search | |||
Su-Shee | moritz_: they said, they'll contact me "end of the week - monday the latest.." | ||
moritz_ | Su-Shee: then I wish you the best of luck | 07:29 | |
sjohnson | moritz_: i am wondering if you think it might work, not so much who the author is | ||
if you have faith, then i will give it my best | |||
moritz_ | sjohnson: it's worth a try. | ||
I've never tried to get something into a core module (except documentation), so I really can't tell | |||
sjohnson | perhaps if i make a good case for it | ||
about how frustarting it is getting an @INC error | 07:30 | ||
on migrating systems | |||
when emergencies happen | |||
... based on a true story! | |||

pmurias | moritz_: re inclusion into Scalar::Util doesn't it contain magical functions? | 10:21 | |
moritz_ | pmurias: dunno, the name doesn't imply that | ||
pmurias | i just read through the function list and most of the functions seemed deeply tied into the perl5 language/implementation | 10:23 | |
moritz_ | C<Scalar::Util> contains a selection of subroutines that people have | 10:24 | |
expressed would be nice to have in the perl core, but the usage would | |||
not really be high enough to warrant the use of a keyword, and the size | |||
so small such that being individual extensions would be wasteful. | |||

literal | how big is the download? | ||
moritz_ | and has no internet connection, and only windows | ||
so I looked around what to download for her | |||
szabgab | so how are the test starting at line 55 in pugs/t/spec/S05-metasyntax/longest-alternative.t passing ? | 10:53 | |
moritz_ takes a look | 10:56 | ||

szabgab | how do you explain $/ is that a magic variable that is both a scalar and an array ? | 11:45 | |
why is the array part not called @/ ? | |||
moritz_ | it's an object. | ||
and @ really only implies the Positional role, % implies the Mapping role | 11:46 | ||
and $/ does both | |||
szabgab | oh so there is an @/ ? | 11:47 | |
moritz_ | no | ||
@($/) or $/.list | |||
lambdabot | Unknown command, try @list | ||
moritz_ | lambdabot: shut up | ||
szabgab | I think these roles and stuff are still way over my head | ||
pmurias | szabgab: $/ is not really magical | 11:50 | |
moritz_ | for a Perl 5 programmer it is ;-) | ||
pmurias | it just gets set after you do a match | ||
szabgab: when you keep an array in $foo "$foo = [1,2,3]" is $foo both a scalar and an array? | 11:52 | ||
szabgab | I think I have to go back to square one and try to understand why do we need to have arrays that have a $ as a sigil | ||
rakudo: my $x = (1, 2, 3); say $x.WHAT; say $x[0]; | 11:53 | ||
p6eval | rakudo 3d5f23: OUTPUT«Array()1» | ||
moritz_ | actually it should be a Capture | ||
pmurias | szabgab: they are array refs from perl5 | ||
szabgab | rakudo: my $x = [1, 2, 3]; say $x.WHAT; say $x[0]; | ||
moritz_ | but $x = [1, 2, 3]; would create an Array | ||
p6eval | rakudo 3d5f23: OUTPUT«Array()1» | ||
szabgab | pmurias, yes I think I understand that but why do we need them ? | 11:54 | |
pmurias | we don't | ||
szabgab | I thought the whole point was automatic reference/dereference | ||
and I was hoping to get a good explanation | 11:55 | ||
or that they will be removed :-) | 11:56 | ||
pmurias | arrays with the @ sigil could be removed without much harm | ||
moritz_ | .oO( then we'd get PHP ) |
11:57 | |
szabgab | I meant to remove arrays with $ | ||
moritz_ | and give up polymorphism? | ||
szabgab | I don't understand how are they consistent with the design | ||
moritz_ | I mean you couldn't create a variable that either holds a hash or an array | 11:58 | |
pmurias | szabgab: Arrays are objects, you can hold objects in scalars | ||
the meaning of a '@' is this container does the Positional role | |||
szabgab | which means ? | 11:59 | |
moritz_ | that you can call .[] on it | ||
szabgab | that you can say @x[3] ? | ||
moritz_ | right | 12:00 | |
%hash[3] will fail. | |||
pmurias | in $x = [1,2,3] $x is a Scalar which contains an Array, in @x = 1,2,3 @x is an Array | ||
szabgab | but you can do that on $x as well if it holds an array | ||
12:00

moritz_ | right, but only then | 12:00 | |

szabgab | so you mean @x can hold only arrays while $x can hold both scalars, arrays and hashes | 12:01 | |
pmurias | you need to use VAR($x) to get at the $x variable | ||
$x can hold anything | |||
szabgab | ok, what about $y ? | 12:02 | |
;-) | |||
pmurias | szabgab: do you see the difference between binding and assigment? | ||
szabgab | not really :-) | 12:05 | |
pmurias | it's obvious once you try to implement binding & assignment ;) | 12:06 | |
moritz_ | my ($x, $y); $x := $y; # now if you assign to $x, the value is also in $y, and vice versa | 12:07 | |
pmurias | binding is like *foo = *bar; assignment is like $foo = $bar; | 12:08 | |

TimToady | those were probably all $+sigspace at the time, which was (at the time) defined to imply one level of caller | 19:04 | |
it currently works because of the stupid translation that gimme5 does, and the resulting support from p5 semantics | |||
so yes, but when I fix that I'll also have to fix gimme5 :) | |||
pmichaud | in the final version, is it likely to become CALLER::<$*sigspace>, or will we have a notation that implies one level of caller? | ||
okay. | 19:05 | ||
I guess the notation that implies one level of caller is CALLER:: :-) | |||
TimToady | I think it's better if it starts looking in this space | ||
pmichaud | oh, I agree | ||
I'm looking to start refactoring PGE to be more STD-like and ran into that. | 19:06 | ||
TimToady | looks like there are a number of places that are wrong that way | ||
pmichaud | yes | ||
it's okay if they're wrong -- perhaps we just want to XXX them for now | 19:07 | ||
I don't mind if STD.pm is wrong in places, as long as we know where they are :-) | |||
migrating PGE to handle some of the new semantics is going to be interesting. I'm starting to think it's easier to start over than to migrate what I already have. | 19:08 | ||
(because then I don't have to deal with Parrot deprecation issues) | |||
I wonder how hard it would be to write the operator precedence parser in NQP | 19:09 | ||
TimToady | well, Cursor does most of the regex semantics, but not all | ||
pmichaud | right | ||
TimToady | doesn't try to do & or && yet | ||
pmichaud | that's one of the significant differences from what PGE does now | ||
so starting over seems easier | |||
TimToady | and it only fakes LTM with a trie | 19:10 | |
pmichaud | is the faking not likely to be good enough? | ||
TimToady | oh, it's good enough, unless you mean "fast enoguh" | ||
*enough | |||
pmichaud | got it. | ||
grammars are essentially subclasses of Cursor? | 19:11 | ||
TimToady | yes | ||
pmichaud | okay, good. | 19:12 | |
TimToady | the current cursor encapsulates the current Match state as well as the current language | 19:13 | |
in theory you could freeze a cursor to have everything you need to provide the setting for an eval | 19:14 | ||
pmichaud | okay. I like this design. | ||
TimToady | but currently the p5 implementation keeps a few things in localized globals just to keep things from getting too slow | ||
pmichaud | it fills in a lot of the "holes" that I've been struggling with for years. | ||
TimToady | and in theory each cursor is immutalbe, and you just continually derive new ones | 19:15 | |
but for ratchet code you can actually reuse them mostly | |||
pmichaud | I hadn't caught that aspect of it.... that's helpful to know. | 19:16 | |
19:16
unitxt joined
|
|||
TimToady | but immutable cursors plus lazy lists is a brain-dead easy way to do backtracking | 19:16 | |
the interesting thing is to see the translation that gimme5 does to STD.pm5 | |||
where it needs to do lazymap vs where it can just get away with conditionals | 19:17 | ||
pmichaud | PGE's model had been to compile regexes into explicit subroutines to do the matching.... is that consistent with STD/gimme5's approach? | ||
TimToady | they're always methods in STD | ||
pmichaud | where the methods are a compiled form of the regex? | ||
TimToady | always methods on the current cursor | ||
yes | 19:18 | ||
pmichaud | fantastic | ||
TimToady | again, you can see how they translate to p5 semantics in STD.pm5 | ||
pmichaud | for the past week or so I've been having trouble getting motivated to write Rakudo code... perhaps that's an indication I need to be doing regex stuff | ||
TimToady | and note that it's hardly using p5 regexen at all | ||
if viv were a bit further along, we could actually emit the rakudo code from it | 19:19 | ||
pmichaud | every time I sit down to make a change in Rakudo, I think "yeah, but I'm going to throw it out once we start doing std-like stuff" | ||
TimToady | but I haven't quite got it to the place where it can replace gimme5 | ||
pmichaud | on another topic, while you're here | ||
did you see the discussion yesterday regarding binding? | |||
TimToady | yes, not really sure what to think about it yet | ||
pmichaud | okay. | 19:20 | |
I'll just re-register the notion that := having semantics similar to signature bind feels more "correct" the more I think of it. | |||
that's the way I'm going to head for now, at any rate :-) | |||
in particular, it matches more closely with the idea that my @a := $v; requires that $v does positional | 19:21 | ||
TimToady | yes, proxies enforcing the additional constraints | ||
pmichaud | correct | ||
TimToady | and for unadorned @a you presumably don't need the proxy | ||
er | 19:22 | ||
unadorned $a | |||
since @a is adorned :) | |||
pmichaud | at any rate, that looks dead-simple to implement in rakudo, and resolves several of the binding issues I had asked about at NPW | ||
it also unifies our binding semantics some what, which I think will likely simplify a few other sections of code that are kinda weirdish. | |||
TimToady | so we can get pure ref aliasing still as long as you do it with 'my $a :=' | 19:23 | |
pmichaud | that works for me. | ||
anyway, we'll head that direction in Rakudo, and if things change later I don't think it'll be a killer for us. | |||
TimToady | still think we need a way of telling primitive binding to allow trailing stuff | 19:24 | |
so that for and map don't have to count args | |||
pmichaud | yes, we need that also somehow | ||
TimToady | maybe it's just an out parameter where it can put the remainder | ||
basically an implied capture parameter at the end | 19:25 | ||
(or parcel) | |||
pmichaud | okay, thanks for the quick tips -- they give me some solid directions to move in | 19:27 | |
