BenGoldberg Hmm, it occurs to me that on the JVM, we *could* pretend to handle SIGINT, via Runtime.getRuntime().addShutdownHook ... 00:54
If you're using bash or a similar shell, then $? will contain the exit/signal status of the last process you ran. 01:02
ShimmerFairy Ah, $? had 130 in it :) 01:05
BenGoldberg: so my guess is that $? (or equivalent) is how camelia produced the (signal INT) message.

AlexDaniel one is a single char, another one has a combining thingy 05:05
my understanding is that .codes should actually say 2
because if not, then what's the point of codes?
.oO( what's the point of a code point )
 05:06
ShimmerFairy AlexDaniel: NFG strings compose to NFC first, in order to minimize the number of 'fake' codepoints that have to be generated. 05:12
AlexDaniel ShimmerFairy: ok, then when “codes” and “chars” will have different output? 05:13
besides obvious cases 05:14
ShimmerFairy AlexDaniel: for Str, it's whenever there's a synthetic grapheme in it.

TimToady dunno why that doesn't count as 1 char...may be a bug
ShimmerFairy TimToady: there's a bug on the devanagari grapheme used at the top of S15, because moar's "grapheme" criteria doesn't work for all graphemes. 05:18
(It checks CCC instead of using the regex for "extended grapheme cluster" specified in UAX#29(?), IIRC) 05:19

TimToady but, yeah
I bet all the surrounding marks are 0
ShimmerFairy wonders how the NYI :uni adverb for strings and/or regexes would ensure that it doesn't mess with the source input's original format, and also supposes that the I in IO should use Uni instead of Str by default, or at least allow it as an option.
TimToady m: say uniprop(0x20dc,'ccc') 05:22
camelia rakudo-moar e7ec20: OUTPUT«230␤»
TimToady yeah, since ccc is about stacking order, and enclosing marks don't have a stacking order... 05:23
ShimmerFairy say "$_.ord.base(16) - $_.uniprop("ccc")" given "\c[COMBINING ENCLOSING SCREEN]"
m: say "$_.ord.base(16) - $_.uniprop("ccc")" given "\c[COMBINING ENCLOSING SCREEN]"

timotimo mhhh, macros to do color things 07:54
Ven has never heard FROGGS++ croak... but he did talk with him 'bout macros and slangs :-)
timotimo ... damn, CRLF as a single grapheme?
that's just weird
i can deal with stuff outside of the ASCII range being unicodey, but ... that? 07:55
masak timotimo: think of it as a ligature :P 07:57
nine masak: Good morning! Before I forget again: I still think LINQ is a job for visitor macros and not for a slang, because LINQ does not introduce any new syntax. It's changing the semantics of existing syntax. And that's something visitor macros are good at.
masak nine: there are two parts of LINQ, as far as I understand.
nine: one part is just ordinary method calls.
nine: the other part is syntactic sugar.
I may be wrong.
nine: anyway, I agree with your general sentiment. if syntax is not changed, then visitor macros can do a good job. 07:58
a lot of the "good job" hinges on the as-yet unspecified Qtree APIs being good. 07:59
nine In a hypothetical Perl 6 LINQ, you'll be able to say my $results = from $table select .foo where .foo > .bar; # from may be a function, select and where could be infix operators and .foo and .bar are just plain mehod calls. Only that the expression is not actually evaluated but changed by the visitor macro to pass a useful data structure to the where operator 08:01
Same for the .foo in the select list
masak that's not valid Perl 6 by any stretch.
there's a TTIAR between $table and select 08:02
nine even if select is infix:<select>?
masak hm.
I stand corrected -- that would work :)
nine \o/
timotimo but how do we get the right $_ in there? 08:04
masak macros.
Ven macros
timotimo oh, i thought we were saying we don't need macros
carry on, then
masak visitor macros are a kind of "we don't need macros" macros :P
nine timotimo: no, we don't need a slang for that. Visitor macros would make implementing this trivial :) 08:05
Ven has been carrying that poor "on" around for a lot, in this functional age
timotimo neato
masak Ven: then you must be really relieved to see visitor macros.
Ven masak: I can implement "on" without visitor macros :P! just look at prelude..
masak Ven: I'm not sure I understand what you mean by `on`, then. 08:06
the only thing I'm not quite clear on is how best to install visitor macros in the parser.
Ven masak: hackage.haskell.org/packages/archiv....html#v:on :P
masak ooh 08:07
timotimo curry on
masak yeah, that reads very well
Ven: I'm curious -- what determines the order in which abc are allocated in the type expression `(b -> b -> c) -> (a -> b) -> a -> a -> c` ? 08:08
Ven allocated? 08:09
masak assigned?
Ven assigned, inferred?
masak I would have expected to see `(a -> a -> b) -> (c -> a) -> (c -> c -> b)`
basically abc picked in order of appearance, left-to-right
Ven ahhh, okay. in a very theoritical way 08:10
masak not that it matters at all -- it was just surprising to me to see b and c first
Ven (sorry, I'm writing gnuasm, so "allocated" has some meaning..)
timotimo i think it's just because the focus of the operator lies on the transformation function 08:11
and if you write it like that, the transformator function has the nice property of being a -> b
masak ah, good point 08:12

ShimmerFairy lizmat: I don't quite follow?
09:21 mprelude joined
lizmat I have this idea of having some type of quoting language that would allow *bytes* to become synthetic graphemes 09:21
and thus allow the regex engine to be used to match binary structures
ShimmerFairy lizmat: hmm... I think a variation of the regex engine that works on Blobs would be better suited, ultimately, but an interesting idea nonetheless. 09:22
lizmat and have some sort of unpack be able to generate the right synthetics out of a binary blob
ShimmerFairy I was writing up my thoughts on the subject, but I don't think I've shared it. I'll take a look. 09:23
brrt curious but sceptical
lizmat in that way, I envision being able to match mixed text and binary structures
brrt what whould you want to do with matching binary structures?
hmm, i already know of a purpose perhaps
lizmat :-)
brrt o5m files (binary xml)
maybe it's a good idea 09:24
lizmat it would certainly reduce the maintenance overhead (only 1 regex engine to support)
brrt current development culture is very much built on the notion that we have to completely parse-and-extract binary files 09:25
for many things that is way too much overhead
lizmat and afaics, it would not require any extra work on the regex engine, as it would just be another synthetic unicode
brrt well, one thing i wonder about is that our current regex engine is not really fast 09:26
lizmat wouldn't / shouldn't the jit take care of a lot of that ? 09:27
09:27 vvz joined
brrt yes and no. 09:27
it is my opinion that rakudo frames are Too Damn Large and Too Damn Nested

ShimmerFairy Ven: aside from the unclear binary - size(8) syntax to specify length, it does look nice (looking at just the first link so far). I think the syntax I've come up with in my gist is kinda similar to it, at least :) 09:42

Ven ShimmerFairy: yeah, it is a bit weird, but has the nice side effect to be extensible/dynamic
lizmat eiro: I don't recall such an (up-to-date) beast to exist at the moment
we've recently had quite a shuffle of classes with the GLR and followup refactors such as the GMR 09:43
pmurias FROGGS: I might be able to reproduce the segfaults with doing make clean; make x100 times haven't cecked yet
ShimmerFairy Ven: I think something that doesn't use subtraction in a _length_ specifier would be far better, in that one case :)
timotimo brrt: i absolutely agree that our frames have to shrink a bit 09:44
yoleaux 09:06Z <lizmat> timotimo: 1. I don't expect push-exactly to be called much, 2 if it is called, it is most likely *not* yet exhausted, so adding extra code for it seems like a waste to me
timotimo brrt: do you have a clue or multiple clues what in particular could be attacked in that area?
brrt well, maybe it's a good post-6.christmas project
no, i have no idea 09:45
timotimo do you think the amount of registers we have is too overheady?
brrt my suspicion is that there are many others who have a better idea
actually, no, i don't think so. i've never run out of GPR registers yet in the JIT
what i do think is that the new jit will need a powerful way to analyse what must go into vm virtual registers and what only has a temporary meaning 09:46

lizmat FROGGS eiro : that's what I meant with up-to-date: EnumMap is dead :-(
ShimmerFairy Ven: correct me if I'm wrong, but the big problem I see in the syntax for Elixir is that there's no room for alternations or anything; a parser for z-machine files, for example, would benefit greatly from being able to use multis for different header versions. 09:49
FROGGS lizmat: well, it is less then a month old... so it can be updated quickly I guess
Ven ShimmerFairy: that's right. you have to do it in several "times". extract it once, "switch" (case) on it, and each case can do its thing differently

timotimo but the ~ operator will call .Str on it, which will give you that warning, because it indicates you've likely got a logic error somewhere
as in: expected a defined string in a string concatenation, but got an undefined string instead
Skarsnik that pretty weird. it does not evaluate the concatenation first? 14:50
timotimo it does
the concatenation is what calls .Str

timotimo did you know you can click on the line numbers and the url will change to include that line number?
it's the zip metaoperator
that line is responsible for adding an empty array as the value for all of names' entries as the keys 15:03
that sentence didn't grammar :?
here's an example:
m: say <foo bar baz> Z=> 1, 2, 3
camelia rakudo-moar e3717e: OUTPUT«(foo => 1 bar => 2 baz => 3)␤»

camelia rakudo-moar e3717e: OUTPUT«{:bar(2), :baz(3), :foo(1)}␤»
timotimo the thing is: Z will stop at the shorter of the two sequences on both sides 15:04
that's why it says [] xx * on the RHS
that's an infinite stream of new arrays
so that the right hand side is never responsible for stopping the sequence
does thath elp?
Woodi hi #perl6 :)
timotimo greetings woodi
Skarsnik ..should the Pg module convert the str to Str? since str are just native type? 15:07
Woodi for me LINQ is a bit baroque and unnecesary mental context switch. an realy how it works ? it already have some ActivRecord fetched from database and just doing .grep( $_ < $a ) or it translates into db engine calls and then fetches things ?
timotimo AFAIK it can also generate db engine calls
Skarsnik: good question; as i said, i didn't our hashes can just hold str objects :) 15:08

Skarsnik how to cast str to Str? 15:25
gfldex there are no spec tests that i could find

i'm not sure how to even pass around a str without it becoming a Str automatically 15:26
Skarsnik let's see
gfldex i believe to remember jnthn write something about unicode Str and str. You may want to ask him. 15:27
timotimo also, are you on latest rakudo?
this is less about unicode and more about boxing
str and Str behave the same way with regards to NFG and unicode and such

PerlJam Skarsnik: you might want to use a post-GLR version of rakudo
gfldex i rakudobugged both shaped hash cases as #126251 15:34
Skarsnik ah yes. %hash{$key} = $value; still give me str in my version 15:35
timotimo if that's the case ... case closed :)
no need to try to debug a multiple months out of date rakudo 15:36
Skarsnik still I would have want the real type of the field x) 15:37
timotimo that's the next step :)

masak who here on channel should I talk to about the implementation of S04's "blocks are conceptually cloned into closures as soon as the lexical scope containing them is entered" ? 19:40
diakopter me me me me
masak \o/
I'm at the point where I need to add something like that to 007, and I'm curious about prior art, war stories, classical no-nos, that kind of thing.
dha Not me. :-) 19:41
masak my first thought is something like this: keep a hash around that maps from containing blocks to lists of (directly) contained blocks. whenever we enter a block, check the hash table, traverse the list, and update all the kids' OUTER. 19:43
oh, and "block" really means "block or routine".
oh, and this needs to work even if a block was added through a synthetic Qtree :) (but that's just a technicality)
I guess in 007 I wouldn't really need the hash table, since the program literally is its AST. but (a) that may change, and (b) the hash is still less work than traversing 19:45
AlexDaniel So I've been thinking about qqx// and stuff, and even though I was bringing this issue up a couple of times I couldn't come up with a nice solution. For those who don't know, the problem is that getting the output of some program is too hard, huffmanly you'll just use qqx// and there you go. What newbies might not understand is that it passes the whole thing to shell, which most of the time is not what you want (and if you want it then 19:47
it's ok to write it out explicitly). So my proposed solution: create two new subs – “runout” and “shellout”. Similarly to “run” and “shell”, but return the str instead (program output). Huffmanly it is correct, since “run” should be preferred over “shell”. If you wish, it is still possible to shell out your security. Upgrading to “run” from “runout” is somewhat straightforward too, if needed (although it wi
you need such extra functionality then it's probably ok). What happens with qqx// then? Just burn it with fire. Comments?
masak AlexDaniel: if you don't feel all that strongly about your own solution, it sounds like a thing that should be explored in module space... :) 19:48
AlexDaniel: "runout" and "shellout" are short, but not very descriptive. even knowing the background, I feel a note of confusion looking at those names. 19:49
AlexDaniel masak: pass_string_to_shell_insecure – I'm ok with this name too 19:50
masak ;) 19:51
AlexDaniel masak: You want me to write a module that will disable qqx//? Can't we just fix that right in the language? :)
19:51 pyrimidine joined
masak AlexDaniel: what I'm saying is "I couldn't come up with a nice solution" doesn't sound like we've arrived at the big wow that makes everything simpler. 19:52
AlexDaniel: I agree with you in principle that qqx// is very convenient, and that that's unfortunate given how injectable it is.
AlexDaniel masak: it solves the problem though
it is very convenient only because it is so short to type it, I think 19:53
masak I don't usually take this side in debates, but... sometimes Perl is just about getting the job done. and you have to trust that people know about security risks.
AlexDaniel nooooo
masak that's how I feel about qqx// -- I'd be sad to see it go.
19:54 pyrimidi_ left
AlexDaniel masak: trusting people to know about security risks… what a wishful thinking! I think we both know about the amount of shell injections out there, it could be great if perl6 could help people just a little bit in that sense 19:54
masak oh, sure. 19:55
I'm not saying we ought to be insecure for the sake of it.
but I *am* saying that we're in a different ballpark here than, say, two-arg open()
where "hey, I could be calling out to the shell" isn't exactly written on the tin 19:56
AlexDaniel and what I've meant by saying that it was hard to come up with a solution is that qqx// is too damn short! There's no way to fix that without removing it… sadly!
masak yes. you're proposing to remove a convenience, for security reasons. 19:57
AlexDaniel convenince? I'm not sure if typing shellout() is much harder than qqx//, except for the quoting stuff
masak listen to yourself :) 19:58
if I didn't want interpolation, I'd use qx//
AlexDaniel masak: like shellout("unsecure $stuff"), what's so hard about it? 20:00
masak: or what would be the use case when that's not enough?
however, most of the time the answer is “you don't want interpolation if you're passing random stuff to shell” 20:01
and if you want it, then be explicit by using a longer sub name. Perfect 20:02
also, there is a word “shell” in “shellout”, which makes it very clear what's going to happen with your string. Just a little reminder, I like it 20:03
masak: but I'd really like to hear a counterexample where just a regular sub “shellout” will not be enough to get your job done (which is now handled by qqx//), when you really need it. 20:05

AlexDaniel hm, other opinions? I'm really touched by the fact that qqx// is there yet there is no safer way to do that with relatively short code, that's disappointing…
just like in perl5 there was “system” that couldn't get the output, so you go dancing around it either with using a module, writing to file or trying to use backticks and sanitizing your input… “run” in perl6 is definitely a strong step forward, yet it's still not good enough to just get the output. 20:14

AlexDaniel yeah, 100% correct huffman coding
And hey, wanna see a live example for this problem? 20:17

lizmat I'd rather hear jnthn's opinion about using 2 hashes for typed hashes, instead of the one like in Bags 20:18

AlexDaniel I've changed rosettacode.org/wiki/Get_system_com...put#Perl_6 to mention run and stuff 21:14
it is probably required to mention that “run“ should be preferred in doc.perl6.org/language/quoting#Shel...ting%3A_qx 21:16
although it mentions it, it doesn't say which one you should choose (and for newbies a sane recommendation is important).

dha So. I want to make a general proposal about function documentation. What would be the best way to go about that in a way that it could be agreed to be implemented? Is that even possible? 21:20
21:20 rindolf joined
dha Or should I just start submitting endless pull requests? :-) 21:21
lizmat dha: you mean you don't have a commit bit yet ?
dha I do, but this would be extensive, and I don't want to just do it without at least a little consensus. 21:24
Basically, as it stands the documentation has the signatures of the functions, but that is probably less useful than the usage statements such as the ones that are in the perl 5 docs. 21:26
I want to propose adding such usage statements. 21:27
e.g. something like gist.github.com/dha/ea03e5c840f7131248de and gist.github.com/dha/e69e8daa6c6519c71060
I'd also like a bit of feedback on format before committing. 21:28
pink_mist thinks that looks great
dha Thanks. 21:29
PerlJam dha++ I second that assessment 21:34
lizmat looks good to me dha++
El_Che a silly question. Once you use sub MAIN in a small script (e.g. for cli params), all the logic must be called from there (as in Java) because the rest of the "naked" script will be called before MAIN? 21:37
PerlJam El_Che: I'm not sure I understand the question. 21:38
timotimo what have i been missing? 21:39
21:39 dha left 21:40 dha joined
PerlJam El_Che: perhaps I do after a little more thought ... MAIN is executed last in the sequence of things (modulo any phasers) 21:40
El_Che: you're not required to call all logic from MAIN, but it's a good spot 21:41
El_Che PerlJam: in most examples laying around it's kind of presented as a magic Getopt replacement.
PerlJam: my point being is that when you use it, you get a typical main block like in Java. 21:42
colomon Any “top level” code before the MAIN will get executed before MAIN is called.
El_Che PerlJam: you can not say something like "i'll handle the parameters from there and the rest everywhere" 21:43
colomon so (for instance) you can play with @*ARGS before MAIN is called
El_Che thx, that's what my play code does,but it's good to get confirmation
Skarsnik Oh run replace the p5 system call? 21:44
El_Che was trying to migrate some p5 to P6 to see how far I got. I was at the command line parameters phase :)
dha So, I got disconnected. People are actually on board with my idea?
PerlJam dha: at least 3 of us.
dha Yay. Ok, maybe I will just start doing things. Thanks. 21:46
jdv79 dha's idea++ 21:47
Skarsnik dha, yes, the Usage statement are generaly more meaninful that just the signature
jdv79 usnt that like alot of man pages?
*isnt
21:47 pyrimidine joined
PerlJam very similar, but better :) 21:48
dha jdv79 - probably, yes.
to be honest, I'm tempted to make separate docs for implementers and users. But that's probably overkill. 21:49
:-)
21:50 pyrimidi_ left
PerlJam way overkill since we switch hats all the time. 21:50
dha Yeah. So gonna keep the signatures. Just add usage. :-) 21:51
PerlJam yay!
dha How do you like the "Defined as:" and "Usage:" headings? Put that everywhere, or just assume people will figure it out? 21:54
PerlJam I lean towards explicit contextual clues rather than implicit, so I'd put them in. Dunno what anyone else thinks. 21:56
dha So noted. I guess my only remaining question, which may not be immediately answerable, is how this will render in the html pages. 21:57
pink_mist if it doesn't render well, someone will /make it/ render well :P

ShimmerFairy dha: if you're working on stringy documentation in particular, you might be interested in the potential rewrite of S32::Str[ingy] I shared a little while ago.

dha Yeah. I appreciate the heads up. Thanks. 23:05
ShimmerFairy dha: I just figured I'd point it out as a source of information (like the $limit parameter on split, for example). Just a heads up that it's not exactly what's currently spec, but for the most part it's just more explanation. 23:06
dha Cool. I'll be wary of introducing anything not yet in. :-) 23:08
