perlnewbee hello :) 00:23
i want to write a parser for some markup language i defined, and i want to try grammars for this. But i dont want to install perl6 in my production env. Can i compile this later to an executable binary? 00:24
timotimo there's different ways to get a perl6 program deployed 00:33
one of which is docker, another is making an installer for windows that contains a custom-compiled rakudo in it
but creating a single executable file from a program isn't yet a thing we have, sadly
perlnewbee oh, ok. Thanks :) 00:34

MasterDuke hm, can't you use flatpack or appimage (i forget which one samcv got working) for that? 00:47
timotimo we do have an appimage of rakudo itself, i think maybe even rakudo star including dependencies? maybe you can use that for a full program 00:51

jmerelo Maybe the best take-home message is that 50% of the issues are solved in 1 day, but a quarter of them take more than 16 days to process 10:44
ufobat: bits in IEEE754 representation?
ufobat yes
jmerelo ufobat: maybe through a Buf? Let me see... 10:45
(meanwhile, posting it in StackOverflow will also get a number of high-quality responses... :-) )
ufobat with unpack() maybe, but that's experimental 10:46
jmerelo ufobat: right. And buf is only for strings, apparently...
pack seems to be only for integers... 10:47
ufobat: maybe stuff it into some Native data structure?
ufobat: right, that might be it... 10:48
ufobat how does this work?
jmerelo jmerelo: trying to find the way... 10:49
ufobat: right, something like this stackoverflow.com/questions/263102...ting-point
using the NativeCall API in Perl 6.
ufobat i was looking through lizmat modules.perl6.org/dist/P5pack:cpan:...P5pack.pm6 but apparently it doesn't implement 'f' and 'd'. or am i mistaken 10:54
because i thought perl5 unpack/pack would do this 10:55
lizmat ufobat: not, sure, it's been a while since I really looked at that 10:56
ufobat: I think we don't have an equivalent for f/d in Perl 6 ? 10:57
ufobat we do have num32 which chould be a IEEE float? 11:01
lizmat not sure... I believe you 11:03
11:03 markong joined
lizmat possibly my work on pack/unpack predates the availability of num32 11:04
ufobat i just know num32 from the NativeCall documentation
Voldenet I believe num32 is a float and Num is a double 11:07
I'm not sure though, but I'd just use Num for both of them 11:09
ufobat i'll ask stackoverflow :) 11:15
jmerelo ufobat: posted my (failing) solution to that problem in StackOverflow stackoverflow.com/questions/500859...sing-the-n 11:16

camelia 1.655684478407693e-09
jmerelo What I was trying to do is to just use memcpy through NativeCall to turn one into another.
Voldenet yeah, every operation gets turned into 64-bit one anyway
ufobat jmerelo, i think memcopy needs pointers? 11:17
Voldenet is rw, maybe 11:19

Kaiepi probably shouldn't try to code with little sleep but that's a way to get it 12:30
m: use NativeCall; my $ptr = nativecast(Pointer[num32], CArray[num32].new(1e0)); say $ptr.deref 12:32

Voldenet But in the end you still end up creating an array

lizmat cono: short answer is no: OOC, what are you trying to achieve? 12:33
cono wrote small recursive algorithm for tree traversing, and was thinking change it to loop or nextwith/samewith provides tail recursion. Will rewrite it to loop, not a big deal 13:08

jmerelo Can I run by you my understanding of what "Normal Form Grapheme" is to see if I got it right? 16:52
Basically, it's a, well, normalized form of implementing graphemes so that they can be easily compared to each other. 16:53
Since graphemes might include several codepoints, you could put those codepoints in principle in any possible order.
timotimo that's already in NFC 16:54
jmerelo OK, but although it's not too clear to me how to do it (I have found only references by presentations by jnthn), the clearest possible explanation I've read is this one: 16:55
NFG needs NFC, and NFC needs NFD
timotimo i don't think NFC needs NFD actually
jmerelo (from 6guts.wordpress.com/2015/04/12/thi...many-rts/)
timotimo or maybe it does 16:56
moritz NFC is a nice idea, but it only works for comparisons and constant-time string accesses if there is a pre-composed character in unicode
NFG lifts that limitation 16:57
jmerelo OK, then two questions.
1. Is NFG a Perl 6 thing?
moritz yes
jmerelo 2. what does it do exactly? I know it's not NFC, NFD or KFC
But it's not clear what it exactly *is* 16:58
timotimo it's a Little Unicode Consortium built into perl6 itself 16:59
incoming strings are eaten up and whenever there's a grapheme that isn't defined yet, the Little Unicode Consortium defines a codepoint for it
for example, someone posts a zalgo string which has LATIN A WITH FIFTY DOTS ABOVE AND THIRTY TILDES BELOW
then the Little Unicode Consortium goes to work:
"clearly there's a people out there who have this character in their native language 17:00
we should define a codepoint so we can properly handle texts in that language"
jmerelo timotimo so far, I *love* this description.
timotimo and the rest of it is just NFC 17:01
it has the benefit that there are no longer any multi-codepoint graphemes in existence anywhere
jmerelo That is why it's constant time, because you use a single codepoint for every new grapheme, instead of several codepoints
timotimo yes
plus the overhead of Little Unicode Consortium meetings
jmerelo The Little Unicode Consortion (let's calle it LUC, or Luke), is that part of the Precomp store, or is it a runtime-only thing? 17:02
timotimo runtime-only
it gets unceremoneously discarded at the end of the program 17:03
jmerelo Poor Luke. He was a good Luke.
17:03 zakharyas left
timotimo basically it's the Phoenix Little Unicode Consortium 17:03
or PLUC
jmerelo So we use the Phoenix Little Unicode Consortium to represent any new Texas-form operator that comes our way? 17:04
It's a Route 66 thing.
But I love the explanation, and I kinda understand it. Thanks! 17:05
timotimo cool
17:06 zakharyas joined
TEttinger how many codepoints are possible for the LUC to define? 17:11
timotimo 2^31 perhaps - 1
i mean 2^31 or 2^31 - 1
because we use negative codepoint numbers for LUC's own codepoints 17:12
chansen_ Is the 2^31-1 limitation perl VM or are these synthetic code points recycled? 17:17
timotimo we do not yet garbage-collect synthetic codepoints, but it is possible

you'll answer your question yourself then
comborico1611 tobs: Thanks for trying! 20:39
Zoffix comborico1611: /./ constructs a regex object. m/./ immediatelly executes that regex. In some contexts (such as smartmatching and bool), the plain /./ also executes the regex
executes it matching against $_
20:39 dct joined
comborico1611 Weird. I haven't read anything about that. Is m/./ advanced? 20:40
Zoffix "advanced"? What do you mean?
comborico1611 Rarely used.
Zoffix It's used when you want to perform the match right away
m: $_ = "meows"; my $match = /.+/; say $match # just a Regex object 20:41
camelia /.+/
comborico1611 Something is going over my head here.
Zoffix m: $_ = "meows"; my $match = m/.+/; say $match # just a Regex object
camelia ｢meows｣
Zoffix *second one should read # now a completed Match
comborico1611 I've read perl6intro.com's take on regex, and Think Perl 6. And both don't explain this. 20:42
Even Docs doesn't explain this.
Granted I didn't read all of regex on Docs, but I scanned it and nothign on this. 20:43
Zoffix It's kind of an irrelevant detail really
tobs m: "abc" ~~ /^a/ 20:45
camelia ( no output )
comborico1611 Zoffix: Someone called it the Regex Match Operator. Does that sound right?
Zoffix comborico1611: and yeah, I'd say it's "rarely used" as it's often uneeded. The only thing is if you want to stick some adverbs that go on the outside, you'd normally write them as `rx:g/./` (because `:g/./` is invalid). However, in many cases you're matching immediatelly anyway, so people tend to use the shorter `m:g/./` version
tobs usually write it like this. I guess the smartmatch operator takes care of applying it, even without m//
20:47 Kaiepi left, Kaiepi joined
Zoffix comborico1611: dunno, it's not an operator in a sense that you have some sort of &circumfix:<m/ /> and it's parsed in the same group as quoters, like qw// or qx// 20:48
comborico1611 Zoffix: I see. 20:49
Zoffix: Why does $_ = "meows"; my $match = /.+/; say match.WHAT output as (Match)? 20:51
Is match a type?
Zoffix comborico1611: rx/./ = "*r*ege*x*" => create a Regex object. As a shortcut, you can skip the "rx" part if you're not using any adverbs; m/./ = '*m*atch' => create and immediately match a Regex object against $_. 20:52
m: $_ = "meows"; my $match = /.+/; say $match.WHAT
camelia (Regex)
comborico1611 My REPL is output of (Match)
timotimo sounds like your rakudo is a month or two out of date 20:53
comborico1611 Err. m/./
timotimo no problem, though
Zoffix comborico1611: What did you type? gist.github.com/zoffixznet/d530022...9c819a61d9
comborico1611: well yeah, the m = *match* so it performs the match and gives you the resultant Match object
comborico1611 with m/./ it is (Match)
without is (Regex)
Zoffix That's right.

comborico1611 Zoffix: Do you mind if I use your examples in an Issue for Perl6 Docs? 20:56
Zoffix comborico1611: ^ and here, despite there not being an m//, a match is performed when the Regex object gets to `so` call, because Regex's .Bool method executes a match. So you could write stuff like ` if /foo/ { ... }` without being forced to use `m//`
comborico1611 Not a big deal if you mind.
Zoffix I don't care about the examples.

Zoffix As for how to remember all that. Dunno, just years of exposure to it.

notable6 lizmat, Noted!
sauvin I have this code: termbin.com/jal4 .. it barfs with "malformed UTF-8". Ran into this before reading from files, fixed it with putting a ":utf-c8" somewhere. Where in this example code would something similar be put?
timotimo the .Supply method call can be told to :bin so you get Buf instead of Str, then you can .decode that as "utf8-c8" if you want 22:28
docs.perl6.org/type/Proc::Async#method_Supply
it also takes :enc("blah") if you like
sauvin Trying that... 22:31
Nope.
Perl6 sure is craploads stickier about this than Perl5 was. 22:32
Very, very annoying.
timotimo where did you put it? :)

sauvin termbin.com/zm4l 22:33
Before you laugh and call me an idiot, no, I don't know perl6 very well yet. :D
timotimo oh that's fine
you would have wanted :enc("utf8-c8") instead, which is like enc => "utf8-c8" 22:34
what you pass instead is utf8-c8 => True
sauvin Probably know in a tiny handful of minutes if that worked or not. 22:35
That might have done it. Why does perl6 barf so easily on "bad" UTF-8 when nothing else I have does? 22:37
timotimo i'm not entirely sure what situations you are encountering tbh
maybe the other systems are just fine with the thought of serving you mojibake? 22:38
sauvin Raw output from my IRC client.
timotimo could very well be due to color codes?
sauvin Hrm... possibly. I'd have to look to see if I stripped those off.

sauvin No, I didn't. You're saying colours and probably things like bolds and underlines are screwing up the UTF8? 22:40
timotimo i haven't looked, but i can imagine it could be illegal utf8
sauvin The colours and suchlike aren't UTF-anything. theyr' 22:41
(grr)
timotimo hm, are they just \x03 followed by two numbers?
sauvin they're "control codes", characters I believe ASCII 0..31.
Something a lot like that. I'd have to dig that stuff up again to find out. 22:42

camelia a
timotimo hm, that seems just fine
sauvin As a matter of fact, last time I screwed around with perl6 and ran into this UTF8 thing, it was on raw IRC logs. 22:43
OK, so it ain't a perl6 thing. It's an IRC thing.
timotimo well, i mean, other irc users are fine sending you binary garbage
ilbelkyr might be non-UTF encodings as well, I suppose 22:44
timotimo sure, utf8 is just used by people who decided that everybody using the same encoding is a good idea, and utf8 is a good compromise 22:45
but the irc server is probably fine spreading any old binary garbage
ilbelkyr yeah, to the irc server it's all just a series of bytes
sauvin The server software itself might just be sending literally whatever binary comes its way.

timotimo with invalid utf8 you really can't win with a one-size-fits-all solution, unless you want to build some machine-learning solution that takes the whole context and tries to figure out what the most likely encoding or meaning is 22:52
22:52 kurahaupo__ is now known as kurahaupo
tobs sauvin: as a heuristic, how about splitting the log into lines and trying encodings until one doesn't fail? (There won't be a single line with different encodings, hopefully.) 22:55
sauvin Hopefully not, but this is IRC, an international thing, and folks from all over the world splutter all kinds of different things. 22:56
Trying to fix my logger atm.
Grr. Fix ain't working. I'll have to deal with it when my head is clearer. 23:02
Many thnaks, though. You told me where the problem is, what needs to be done about it, and that time spent learning perl6 isn't wasted. 23:03

sauvin Can't blame the hammer if the nails are made out of acrylic. 23:04
timotimo ouch :)
sauvin Oh, it'll be an easy fix. I've run into exactly this once before, many years ago. Wound up stripping off colours manually before I found a module for it. 23:06
Ain't working, for some reason, but the logger is in perl5 and so probably not on topic here.
timotimo well, perl6 fancies itself a glue language, so other languages aren't fully off-topic if you're interacting with a program in that language :) 23:09
23:09 rindolf joined
sauvin Perl5 fancies itself the same. Funny kind of glue, though: it does EVERYTHING. 23:09

comborico1611 How do I add say WHAT onto this: say my $st = (my $string = "banana").comb 23:26
Zoffix sauvin: FWIW, here's how IRC::Client module handles IRC content. Just `try`ies to decode it as utf8 first and then fallsback to latin. Seems to work OK: github.com/zoffixznet/perl6-IRC-Cl...#L206-L208 23:27
comborico1611: why do you need a `.WHAT`?
comborico1611 I'm wondering what comb returns
( a b c ) 23:28
Seq, right?
Zoffix comborico1611: you mean print the name of the objecT?
timotimo yes, it gives you a seq. if you assign seqs into @foo or such, it will be turned into an array
comborico1611 Zoffix: Yes.
I'm still pretty fuzzy on these objects. Match object and Seq object... are classes? 23:29
I mean objects of classes.
Zoffix comborico1611: then use `.^name`, not .WHAT. .WHAT returns the type object not a string. It's a fake method and so doesn't work in some contexts, and a gist of a typeobject prints just the shortname, not the fullname.
m: my $st = (my $string = "banana").comb; say $st.^name
camelia Resource temporarily unavailable
timotimo almost everything is an object, objects are instances of classes
Zoffix e: my $st = (my $string = "banana").comb; say $st.^name
evalable6 Seq
Zoffix comborico1611: and that's not a good way to store a Seq. You're shoving it into a container, so other operations on it would treat is as a single item rather than the contents of it 23:30
comborico1611 I thought Perl6 was really procedural that pretended to be OO.
Zoffix e: my $st = (my $string = "banana").comb; for $st { .say }
evalable6 (b a n a n a)
Zoffix You should bind instead
e: my $st := (my $string = "banana").comb; for $st { .say }
evalable6 b
a
n
a
n
a

Proactively remove temp files

While the module will remove them, if the script aborts for any reason, they stick around. This removes them as soon as possible instead.
Closes #1973		 23:31
Zoffix sauvin: "Why does perl6 barf so easily on "bad" UTF-8 when nothing else I have does?" Because we decode as UTF-8 by default, while other things give you bytes and require you to do the decoding yourself and many programmers aren't even aware their programs can't handle unicode properly because a few ASCII strings they tried in their program "work". If you do decode them, other things barf just the same 23:39
$ perl6 -e '$*OUT.write: Buf.new: 200' | perl -C -wlE 'say for <>'
utf8 "\xC8" does not map to Unicode at -e line 1, <> line 1.
Malformed UTF-8 character (unexpected end of string) in say at -e line 1, <> line 1.
comborico1611 Goodbye! 23:41
23:41 comborico1611 left
sauvin Makes sense. When I made that statement, I wasn't taking into account the only things I'd worked with was stuff containing IRC color codes, which probably aren't part of UTF-*anything*. 23:41
Zoffix Wonder what ruby does, 'cause based on the manpage, this should enable utf8 on stdin: perl6 -e '$*OUT.write: Buf.new: 200' | ruby -U -e 'puts $stdin.readline()' 23:45
Yet, it just prints an "unknown char and doesn't
throw
Zoffix smiles at comments on this answer "terse and readable": stackoverflow.com/a/21329178/2410502 23:47
Considering Perl 6's version is just `slurp "test.txt"` :)
timotimo easy to cherry-pick pieces where perl6 code is so much nicer ;) 23:48
but try this! $foo + $bar * $quux - $bleh ** $plop
you can hardly make that better in perl6 than it is in ruby! :P 23:49
checkmate butterflyists!

m/ / and / / examples added

Added examples to help illustrate difference between m/ / and / /. Zoffix provided the examples. I provided the learning. An example for rx/ / is needed. As a newbie, this info is very helpful and rare. It is not in Think Perl 6, ttbomk. And definitely not in Perl6Intro.com. Needed info or something better.

Formatting fixes

  - Use proper C<> blocks instead of quotes
  - Clarify output in examples to show object names		 23:51
Zoffix timotimo: what is it in ruby? 23:52
timotimo probably the same, really
Zoffix Ah :)

AlexDaniel being silly a little bit is fine 23:54
timotimo but if it's not screwed on right, wouldn't screwing it left unscrew it even further?

.oO( but the flat earth part was too much, IMO :) )
timotimo i'm not sure why i brought that up, yeah
