i haven't tried it so far 01:59
jackson I'm extremely new to perl6
01:59 jackson is now known as Guest77700
Guest77700 could anyone help me with grammars? 01:59
timotimo you've come to the right place
adu timotimo: on the contrary, I've been taking 3mg of Melatonin for 10 years now, I'm kind of addicted
timotimo oh
i suppose the body gets used to the stuff being supplied externally?
Guest77700 I take up to 8mg of melatonin every night lmao
adu timotimo: I'm not sure if I know if my brain can produce Melatonin on its own anymore... 02:00
timotimo i suppose i'll not try it, then :)
anyway, i'm off 02:01
see ya!
adu timotimo: good night
TEttinger melatonin was interesting for me
I slept super deeply, but I woke up feeling unrested because my dreams were so intense and lifelike
it was like i had just spent 8 hours dodging north korean spies and ghostbusting giant mi-go, which was my dream last night 02:02
Guest77700 So I have a file full of lines that are formatted like so: '<number>:<time>:<ipsrc>-><ipdst>:<protocol>:<size>:<srcport>:<dstport>', and example of a line being '1:0.000000:192.168.1.104->216.18.166.136:TCP:74:49859:80' 02:03
How would I write a grammar to parse each line and pull out values I need?
I've written something I thought would work, but it didn't end up working 02:04
hoelzro MasterDuke: there *is*, but it's kind of tricky
yoleaux 01:04Z <MasterDuke> hoelzro: with vim-perl syntax highlighting, is there a way to highlight strings delimited by curly quotes (e.g., <“ ” ‘ ’>)?
hoelzro since we can't rely on Unicode properties, we basically need a syntax rule for every possible pair - and there are a *lot* of them 02:05
gfldex m: dd '1:0.000000:192.168.1.104->216.18.166.136:TCP:74:49859:80'.split('<-')>>.split(':')

gfldex Guest77700: ^^^ a grammar is overkill (and slow) for your usecase
m: dd '1:0.000000:192.168.1.104->216.18.166.136:TCP:74:49859:80'.split('->')>>.split(':') 02:06
camelia rakudo-moar 6183a5: OUTPUT«(("1", "0.000000", "192.168.1.104"), ("216.18.166.136", "TCP", "74", "49859", "80"))␤»
MasterDuke hoelzro: i'm guessing it's not turned on by default?
hoelzro MasterDuke: what isn't turned on?
MasterDuke the highlighting for unicode quotes
hoelzro well, it's not present 02:07
we only accept some of the more common pairings
like "...", q{...}, etc
MasterDuke i see you saw my github issue. is that likely to get implemented? or should i try to just add it to my local perl6.vim? 02:09
hoelzro MasterDuke: if I can figure out a good way to implement all quotes, I will happily do it 02:10
but it's tricky, because the more rules we add to perl6.vim, the slower it gets
MasterDuke i have noticed it's not the fastest syntax highlighting 02:11
hoelzro yeah =/

AlexDaniel hoelzro: “a *lot* of them” – well, just 11, that's not too much. Although I probably need to dig into the grammar to see if I missed some 04:04
hoelzro: that being said, supporting just ｢｣ ‘’ and “” is probably a good start :) 04:05
llfourn benjikins: you can make an immutable hash with Map.new 04:11
AlexDaniel Yeah, that's it. (if anybody is interested: github.com/rakudo/rakudo/blob/nom/...nqp#L3541)

cbk Anybody know if mod_perl works with the current Perl6? 04:23
llfourn cbk: it won't 04:27
cbk llfourn, so is there any way i can just write a simple Perl6 cgi script? 04:28
llfourn well you can use one of the p6 HTTP servers 04:29
but I don't think there is any rakudo integration with anything that would make it like cgi 04:30
github.com/ufobat/Bailador # I think ppl use this
cbk OK I'll look. really just wanted to have a simple cgi script though. 04:31
llfourn, Thanks. 04:33
llfourn cbk: it looks like some people have attempted to do some cgi like things: modules.perl6.org/#q=cgi&sort-c...sort-dir=d
YMMV
though tbh for me developing with app servers is simpler than cgi 04:35
04:37 Cabanossi left
cbk llfourn, I already have Apache running, I just want a Form that will pass data to an Perl6 cgi script. super simple nothing more then that. 04:37
hoelzro AlexDaniel: did you look at src/HLL/Grammar.nqp as well?
my last count was 196 pairs
(by this I mean Unicode bracketing characters, any of which may be used as a string delimiter with q and friends) 04:38
llfourn cbk: unfortunetly I don't think we have apache integration :( 04:39

cbk llfourn, Yes I saw that, and tried those but they do not work 04:39
Hope it gets added to the TODO list.

gfldex cbk: implementing CGI by hand isn't that hard. 04:40
benjikins Does anyone know how it would be possible to convert parsed data from a pcap file (individual packets) to something like .flow files (netflow)
llfourn knows nothing about implementing cgi 04:41
cbk gfldex, I think I'm having problems with Apache and not really Perl6.
gfldex cbk: cgi should not be activated by default, IIRC all you need to do is to set the cgi dir 04:42
llfourn but woulnd't you need to make mod_rakudo or something for apache? 04:44
cbk gfldex, That was done, Perl 5 cgi scripts work just fine. As soon as I change a working perl5 script to use perl6 it stops working, and I get an internal error.
llfourn cbk: right because it's using mod_perl which embeds a p5 interpreter inside apache 04:45
gfldex cbk: may be a missing PATH or some other ENV vars
llfourn (as far as my understanding goes?)
gfldex the error log should tell you more 04:46
cbk I have #!/home/user/.rakudobrew/bin/perl6 as the shebang line
gfldex, You maybe right, I think my install of perl6 is messed up. only setup for my user account. 04:47
gfldex cbk: the user apache is running with may not have access to those files (if it does, shame on you :) 04:48
cbk gfldex, I have not changed any of the default file permissions for apache nor Perl6. So I don't expect that It would have access in that way. (hope not) 04:53

currently is export trait works like a charm for exporting from one module into the useing module but I'm wondering how to export up another level 05:03
for example if I export subroutine foo from module A and then import it into module B how do I export A::foo to any module which use module B 05:04

moritz the search isn't a fulltext search 12:26
it only makes sub/method/operator defintions available, and things specificially marked with X<...>, iirc 12:27
tbrowder BTW, it would very cool to have the build log dir either: split to show latest and all others in a subdir or a listing in reverse time order (latest first), or, better, both. 12:28

nine Speaking of custom ops: what do you guys think of using a custom op to communicate to Inline::Perl5 that it should call a Perl 5 method/function in scalar context?
unmatched} All I'm reminded of is the startup penalty with custom ops. 12:58
perlpilot nine: $= $p5-obj.method; # :-) 13:01
13:02 mcmillhj joined
[Coke] nine: like prefix:<scalar> ? 13:04
nine [Coke]: that would certainly be the most intuitive. I'm not sure however if that would even be possible as surely the op's arguments are evaluated first and this op would need to change the way the argument's evaluated 13:05
masak unmatched}: yes, I had the thought about `default` not being needed when I wrote it. still, it adds some clarity, IMHO. 13:08

pmurias nine: what happens to named arguments passed to a Perl 5 sub/method? 13:11
13:11 lvr left 13:13 sufrostico joined
nine pmurias: ok the issue is definitely not worth creating a slang. 13:14
pmurias: named arguments are turned into key/value pairs
lizmat masak unmatched} sometimes I wish we had a "ternary" syntax for handling -1,0,1 13:15
pmurias nine: so p5sub(:abc(123)) is turned into p5sub('abc', 123)? 13:16
lizmat cause the "beats" is a lot like "cmp"
DrForr Balanced ternary is a common numbering system.
unmatched} nods
nine pmurias: yes
DrForr :3b(+0-)
pmurias nine: scalar($obj).foo(123, ...) would be possible 13:18
nine So far I've found 3 different ways to implement scalar/list context for method/function calls: 1. have a custom call operator for scalar calls (maybe -> for old times sake? ;), 2. encode the context into the method name: $foo.do_something-s(...), 3. use a sentinel value as first argument: $foo.do_something(P5Scalar)
13:20 adu left
pmurias nine: options ones seems really ugly 13:21
* option one
psch do the insane, almost-timetravel one! clone the p5 interpreter in memory, call both contexts, and then create a Perl 6 object wrapper that returns the needed one and deletes the wrong clone
unmatched} option three as well
13:22 ufobat left
masak lizmat: that should be possible with `is parsed` macros 13:22
lizmat: I just sketched up this one for 007: github.com/masak/007/issues/163
pmurias nine: method chaining also would be possible: $obj.scalar.foo(123, ...) 13:23
nine I've thought the method name one is the perfect solution because in Perl 5 function names cannot contain hyphens anyway. But then github.com/niner/Inline-Perl5/issues/67 came along and I found out that it's actually possible to call a function with a hyphen in its name in Perl 5 13:25
masak nine: betting against Perl 5 being able to do a thing (somehow, no matter how unsavorily) is a dangerous game :P 13:26

moritz hello jkramer
jkramer How do I start the perl6 shell with 2016.07.1? I upgraded recently and when I start perl6 without any arguments now I don't get the prompt anymore. 13:29
unmatched} jkramer: that still should be the way. What OS?
jkramer FreeBSD 13:30
nine mst: looks like something very much worth investigating!
mst nine: and the :: in perl5 makes for dispatch via that package
jkramer Both the 2016.04 and 2016.07 were built from rakudo star, if that changes anything. But with 04 I got the REPL shell
mst nine: see also p3rl.org/curry
nine mst: I wonder if the same trick works in Perl 6 13:31
unmatched} tbrowder: I recall in the past the indexer having issues with tags inside of it, so X<B<foo>> would have to be written as X<B<foo>|foo>
tbrowder: and another one is issues with X<> not working when used in =head.... not sure if the same is the case for =item 13:32
jkramer Actually when I start perl6 without arguments there's a moar process that used 200M (growing) and 50% CPU while doing nothing (visibly)
unmatched} jkramer: what happens? Does it just exit or is there output?
or does it hang 13:33

n0tjack I'm trying to fiddle Zoffix's neat rock-paper-scissors script by substituting cutesy emojis where he has words, but p6 doesn't seem to like them. 16:00

Is there any way to get p6 to accept those emojis as enums and function names?
jast moritz: the only meaning of 'stepback' that I've seen so far relates to furniture 16:01
moritz n0tjack: only characters that are identifiers can serve as enum values or constants 16:02
jast: ok, then I might have picked up some unidiomatic English there
n0tjack I can't hack my way around with something like "\xFFFF" or whatever the unicode code points are?
jast the phrase 'step back' is more common

16:37 pierre_ joined
unmatched} Considering there are developers in the channel who wrote that code, sure someone knows :) What's the actual question? 16:38
timotimo easy to find out
just check out the moarvm source and look into src/6model/reprs/, where you'll find the VMArray.h and VMArray.c files
lambd0x memory management performed by rakudo for array type
timotimo: that helps :) 16:39
16:41 labster joined 16:43 pierre_ left
jnthn Also src/core/Array.pm and src/core/List.pm (Array inherits a bunch from List) are relevant 16:43
lambd0x thanks. Want to know because I plan to use this language in a algorithm complexity course in my university.. 16:44
timotimo it's good to point out that our VMArray uses "realloc", which apparently has some implementations that have their own heuristics when it comes to growing memory regions 16:45
i.e. they sometimes grow more than requested and will then do future growth requests without doing copies 16:46
i forgot who told us about that
ilmari glibc has malloc_usable_size() which tells you how much was actually allocated 16:47
timotimo oh that's helpful
hoelzro TIL 16:48
ilmari++
I only knew about mallinfo
ilmari OSX has malloc_size() and malloc_good_size()
lambd0x hm... but its use of realloc is subjected to internal fragmentation?

ilmari hoelzro: is that for when you decide memory management is hard and go shopping?

dj_goku so if I wanted to hack on the perl6 REPL this is what I want right: rakudo/src/core/REPL.pm 21:33
hoelzro dj_goku: yup 21:34
dj_goku hoelzro: sweet. I have a few functions I want to add. Not sure how easy it'll be. 21:35
hoelzro dj_goku: what kind of functions? 21:36
dj_goku ls/pwd(this would probably just call another function)
nothing really special
make chdir
hoelzro hmm
dj_goku most REPLs have that and is really helpful. 21:37
21:37 FROGGS left
hoelzro would ls call run 'ls', or would it list the symbols in the current scope? 21:37
dj_goku run ls
hoelzro is it too much to do run 'ls' or do dir '.'? 21:38
I dunno - I (personally) tend not to like it when REPLs contaminate their environments with functions that are shell-like 21:39
it would be nice, imo, if we allowed an RC file of sorts for the REPL, so users could stick whatever functions/etc they want in there
dj_goku ahh I live there, maybe that isn't the best way to figure things out.
hoelzro: so in python I use ipython and it is great. I just started checking out the elixir REPL. THey both have LS, but ipython has a lot of shell-like. Where elixir only has ls/pwd 21:41
arnsholt The neat thing would be to have a module where you can sort of 'use Shell::Commands qw/ls rm/' and it generates ls(*@args) and rm(*@args) for you, that call the right programs with the args
hoelzro see, I don't mind if someone wants to build a fancier REPL ala iPython 21:42
I just don't know if that kind of functionality belongs in Rakudo itself
dj_goku ahh. well I have no idea of hacking a new REPL so I just wanted it in the rakudo repl. :D
arnsholt There's always the Perl 6 ipython kernel 21:43
I'd be happy to hand out commitbits =)
dj_goku arnsholt: I think I remember being told about that. so Perl6 <==> ipython kernel? 21:44
