augustus hello, anybody hanging out here? 09:11
felher Who wrote the 'project euler' blogpost?
o/ augustus
diakopter augustus: what's up 09:12
augustus well i just got the latest from git, it's been about a year since I did 09:13
wanted to check and see how some things were working, particularly phasers
it seems like some things work better, but it's hard to tell since the old version doesn't run anymore I guess
09:15 marloshouse joined
sorear hey augustus 09:16
augustus yes sorear?
felher augustus: I can not comment on old versions not running anymore. But since you noted that you are interested in phasers -- there will be a perl6 advent calendar post on the fifteenth which is named 'Phasers set to stun: some neat use case'. You might want to read that :) 09:17
augustus I will certainly, it is an important topic to me ;) Mostly I wanted to find out if there was more current documentation on them
they seem to work about 50% or so? 09:18
but it is hard to tell what is intended vs what is not working yet
diakopter augustus: I'm curious, why phasers 09:19
09:19 am0c left
tadzik augustus: how about perl6.org/compilers/features? 09:19
sorear o/ tadzik 09:20
tadzik bah. I found a screenshot from a project I once started, but I can't find the code anywhere :(
sorear: o/
augustus diakopter: features that promote correctness appeal to me, and phasers promote correctness ;)
tadzik: I mean in the itty little details; phasers are *there* but don't always work as intended (?) 09:21
tadzik if they don't, it's a bug to be filed :) Any particular example>?
FROGGS IMO jnthn was working on phasers within the last two months and fixed stuff 09:22
tadzik that's more of a fact than an opinion :)
augustus well for one, UNDO never triggers and KEEP doesn't trigger except when loop naturally loops. hard to tell when they are supposed to trigger
FROGGS augustus: see this for example: github.com/rakudo/rakudo/blob/nom/.../ChangeLog 09:24
augustus FROGGS: thank you, I had looked at the latest changelog but should review further back 09:25
FROGGS augustus: here are the spectests for phasers: github.com/perl6/roast/tree/master/S04-phasers 09:26
so you can see what is working 09:27
augustus FROGGS: Thank you, I will look through those to see how they are supposed to work 09:30
FROGGS ya, but I dont see UNDO or KEEP there...
maybe NYI
09:31 am0c joined
augustus they have keep/undo, but only with respect to functions, not loops 09:31
and I'm guessing that the return value evaluating to True in a boolean context is what determines which gets run? 09:32
although my expectation on KEEP/UNDO has to do with exceptions being thrown or not 09:33
09:33 fhelmberger joined
sorear loops are a kind of function. 09:34
niecza has KEEP and UNDO but not fail. I don't like fail.
09:35 wamba joined
augustus sorear: what I meant was that the test code provided does not included a loop, and I have been unabel to trigger an UNDO within a loop. 09:36

augustus jnthn: ok, that is good to know.
jnthn: I take it Mu is undefined? 09:43
jnthn augustus: Well, undefined values in Perl 6 are represented by type objects, so you can have typed undefined values. But Mu is the most general kind of undefined, yes. 09:44
sorear Mu is undefined
Any is undefined
5 is not undefined
jnthn But Int is 09:45

sorear augustus' question is quite cromulent if you interpret "undefined" as an adjective :p

jnthn um, that's certainly wrong. 09:48
sorear augustus: I did not realize that was a rakudo-specific question
augustus sorry, I have rakudo, but my question relates to how thigns are supposed to be
i don't know for some if it's intended or not
jnthn augustus: Niecza gets this one right, Rakudo has it wrong in this particular case.
augustus ok I see 09:49
sorear jnthn: I think next is specced to take a return value in at least one case (not the obvious one)
jnthn r: loop { LEAVE { say "undo called" }; next }
p6eval rakudo e2f2dc: OUTPUT«(timeout)»
jnthn At least it's consistently wrong...
sorear jnthn: so I would conjecture that plain next uses Nil, which is undefined
jnthn sorear: OK, makes sense. 09:50
sorear learned a new name recently: penumbral argument
augustus Another quick question: if a block exits by an exception being thrown, that will be undefined and trigger UNDO? I get an error about &throw being an undefined function so I don't know how to throw an exception
sorear augustus: exceptions are thrown by "die", and that absolutely calls UNDO 09:51
augustus when I tried die, the program just ended
is "throw" no longer being used then?
sorear did you have a CATCH in scope?
augustus no
sorear throw was never used in Perl 09:52
augustus hmm I googled and found some perl6 thing using throw lol
sorear I think you may need CATCH or try to get a stack unwind
r: LEAVE say "bye"; die "cow" 09:53
p6eval rakudo e2f2dc: OUTPUT«bye␤»
sorear r: UNDO say "bye"; die "cow"
p6eval rakudo e2f2dc: OUTPUT«bye␤»
sorear maybe some p6eval weirdness
augustus ok with a CATCH, die does what I'd expect, thank you. 09:55
can you explain how CONTROL works? It triggers for me on next/last, but I when I say $_ it doesn't tell me what triggered it 09:56
jnthn guesses he should take care of $dayjob tasks before looking into the next/last...

Niecza does.
10:07 am0c left
augustus what else generates control exceptions? I wouldn't think next/last were so common. And is there some element of that output which I can use to distinguish between next/last? 10:07
or rather I guess, since you suspect they might be cheating a little, do you know if it's intended that $_ can be examined to make this distinction? 10:09

sorear augustus: at one point in the past you could inspect $_ in CONTROL in Niecza, but that feature seems broken 10:18
augustus ok, thanks for all your help.
sorear augustus: it was never very useful, the value in $_ was just a small integer code like 3 for last :D
augustus: I think eventually there should be spec for this
augustus well if it was well defined
jnthn Maybe they should be typed exceptions...
augustus yes so long as it's specced and you can count on it
jnthn X::Control::Next etc.
Guess moritz++ may have a take on this. :) 10:19
augustus i would vote for that
if I had a vote lol ;)
if they were typed, then would CONTROL just be an alias for CATCH then?
sorear flussence: private attributes cannot be assigned in constructors or inspected using .perl, because it makes Damian sad
jnthn augustus: No 10:20
flussence sorear: oh, thanks
10:20 bloonix joined
augustus jnthn: because control exceptions aren't like other exceptions I take it? 10:20
sorear flussence: if people keep coming in here with that question I'll revert the spec change
p6l thinks purity of the "private attribute" concept trumps usability 10:21
I acquiesced then, but my regret only grows 10:22
flussence it's definitely not following POLS. I think I just wasted 2 hours looking for a bug that wasn't there...
augustus sorear: when you are posting ouput from niecza is that from an online evaluator, or are you copy and pasting from your local machine? 10:24
jnthn augustus: Something like that.
augustus jnthn: ok some exceptions are more equal than others lol :) 10:25
sorear augustus: look carefully, the replies are not coming from sorear...
jnthn sorear: Not being able to refactor your privates safe in the knowledge you aren't breaking API is also a usability issue. 10:26
augustus yes, I saw that, which is what made me suspect an online evaluator, but I wasn't sure
ohh is that what the n: does? run in niecza?
and r: rakudo I'm guessing lol 10:27
flussence jnthn: would be helpful if it at least threw a warning there to say that code's wrong...

masak submits rakudobug
I'm sure I could sit down one evening with the phasers, go through S04 carefully, and shake out two or three bugs ;) 10:44
sorear: I'm fine with reverting the pure privateness of private attributes, but I think it should be accompanied by a proper discussion, just like last time. 10:48
jnthn for one is not fine with it. 10:49
augustus masak: not sure if this is strictly related to phasers or if it's a bug, we were also discussing how/whether next/last could trigger UNDO (for example saying next Mu;) and how you could tell which CONTROL exception triggered from within a CONTROL phaser
masak sorear: keep in mind that even *without* .perl and constructor arguments, Perl 6 leans heavily to protecting the private attributes. you can't even reach them in a derived class or 'augment' re-declaration. 10:50
augustus: yeah, it's possible that that needs clarification, actually.
augustus personally, I would want a way to do next/last with a rollback, but would expect the default to KEEP. it seems the rakudo bug is skipping the entire LEAVE sequence if that helps 10:52
jnthn LEAVE and KEEP vs UNDO are handled it the same place, so if it's skipping one of them it'll be skipping the lot.
masak leaving a block should always trigger LEAVE, and exactly one of KEEP/UNDO. 10:53
jnthn Right.
augustus ok
masak (that's not to say that an individual block can't have several phasers of these types, of course) 10:54
augustus right; begin-type phasers go in order of declaration, end-type in reverse order right? 10:55
masak right. 10:56
10:56 grondilu joined
augustus and they're some kind of attribute that you can manipulate at run time right? 10:56
grondilu I got a "No object at index 164" when trying to (re)bootstrap panda 10:57
masak grondilu: that's a serialization error. could be due to version skew. 10:58
...somewhere.
jnthn Probably stale .pir files somewhere
grondilu oh I know
I remember panda asking me to manually compile something last time
jnthn I thought I'd nailed the various pre-comp bugs and could start on some automated handling of that but I seem to recall hearing there still is at least one... 10:59
tadzik panda asking to manually compile stuff?
oh my. It became self-conscious

well, removing the pir or recompiling it didn't solve the problem anywya 11:01

augustus masak: It is possible to do policy injection by dynamically adding/removing phasers?
tadzik =cut is a legal Pod Block name
masak rindolf: yeah, it looks it. it's insufficiently translated.
jnthn tadzik: ah, yes :)
tadzik so you can =cut, or =begin cut, or =para cut
but we should probably warn if someone does that
like, when would you mean that? Probably never
masak tadzik: we should probably error if someone does that.
tadzik maybe even error, yes
masak tadzik: '=cut' is all-lowercase, so it's reserved, no?
then we can error.
tadzik true 11:08
rindolf Confused again. 11:09
What kind of an error message is "confused"?
masak a bad one. 11:11
we do our best to replace it with better ones when we can.
STD is still state-of-the-art on this.
jnthn rindolf: It means "There's a syntax error that the parser can't classify any better for you"
masak Niecza does better than Rakudo, but Rakudo is getting there.
rindolf jnthn: well, it points to line #1.
masak rindolf: generally, if you know Perl 6 syntax, you won't get many "Confused" error messages. 11:12
jnthn rindolf: Yeah, 'cus Rakudo doesn't implement the highwater algorithm yet.
rindolf masak: don't look at me - I'm just a code monkey.
11:12 anuby left
jnthn At least once we have that we'll be able to give a much better idea of exactly where things came unstuck... 11:13
rindolf I take orders, and perform them in the worst possible way.
paste.debian.net/214497/ - well this is what I have right now - should I use STD on it?
masak rindolf: not passing judgment. just letting you know that "Confused" isn't all that common once you know the syntax. 11:15
rindolf masak: OK.
masak rindolf: we should still fix those errors to be better for new users, of course. 11:16
rindolf masak: yes, indeed.
masak: also the line number.
jnthn If I can catch enough of a break from $dayjob stuffs, I should get at lesat the position bit of the highwater stuff in for December Rakudo release, which should mean we get much better position info in cases like this one. 11:17

12:03 yves_ left
moritz right 12:04
moritz wants 'is rw' renamed to 'is assignable'
jnthn yes, first arg is the declarand 12:05
masak moritz! \o/ 12:06
augustus lets see, now to assign a trait to an anymous block, do I have to use a different syntax for the block? It won't take {...} is trait
masak moritz: 'assignable' doesn't seem Huffmanly right.
moritz masak: but 'rw' and 'ro' carry conotations that confuse the user 12:08
jnthn We could always abbreviate assignable to...er, let's not :P 12:09
FROGGS hehe
augustus 'rw' and 'ro' just seem archaic, not wrong, but weird when the rest of perl 6 is so umm... modern?
masak moritz: I think the whole concept of readonlyness is still unresolved in Perl 6. especially between container objects and their contents. 12:11
augustus S06 specifically says you can't put traits on "Pointy Blocks." how do I assign traits to blocks? 12:13
jnthn You can add them to both using the "also" syntax 12:15
r: sub trait_mod:<is>(Block $r, :$lol!) { $r does role { method lol() { 42 } } }; my $x = -> { also is lol; }; say $x.lol
p6eval rakudo e2f2dc: OUTPUT«42␤»
jnthn r: sub trait_mod:<is>(Block $r, :$lol!) { $r does role { method lol() { 42 } } }; my $x = { also is lol; }; say $x.lol # I think this works too
p6eval rakudo e2f2dc: OUTPUT«42␤»
augustus ah, inside the block 12:16
jnthn yes, preceded by an "also"
btw you can do this generally
class Foo { also is BaseFoo; } # can write the inheritance stuff like this
augustus I take it a Routine IsA Block? 12:17
jnthn Yes
augustus ok. On a conceptual level, would you consider it better to assign phasers traits or roles to denote what policy they are implementing? 12:18
I understand the trait in turn assigns a role
moritz it totally depends on what you do 12:21
some traits simply change existing attributes
others (like "is export") only change external information
12:21 yves_ joined
augustus yes, sorry, not all traits would assign roles, but in order to retain information all the way to runtime, you have to assign a role yes? 12:22
12:22 bowtie joined
augustus *well, add new information and have to stick around. I understand you could change existing attributes without assigning a new role 12:23
jnthn augustus: If you want the information to be attached to the object, and the object doesn't already have a way to model the information, yes, you'd want to mix in a role.
moritz if you want to attach extra information to an object which you don't control, yes, you'd mix in a role 12:24
jnthn++ was faster :-)
jnthn :)
augustus let me be more specific. Lets say I want to scan existing phasers of a block, and see if any of them implmenet Policy X (potentially version Y from Vendor V etc etc). If so, remove them, and add my own implmentation of Policy X. This Policy meta-data, would you figure you assign it with a trait, or just adding roles directly? 12:27
This seems like a gut-feel question, not a right or wrong kind of question ;) 12:28
jnthn throws in a cautionary remark about &foo.phasers being somewhat experimental and not actually in the spec yet :) 12:29
12:29 benabik left
jnthn But yeah, you would probably find traits the most convenient way to attach the info. 12:29
NEXT { also is SomePolicy; blah... } 12:30
augustus ok, this is the vibe I was getting. Thanks for the feedback. 12:31
oh, and I think that this kind of policy injection is a significant use case, so I would encourage &foo.phasers to be formalized so module writers can depend on it :) 12:36
jnthn augustus: Well, as with all meta-programming stuff, it's trying to stike a difficult balance between giving implementations the flexibility they need to evolve and providing a common API for fiddling. 12:37
dalek rlito: f15277a | (Flavio S. Glock)++ | README-perlito5-js:
Perlito5 - js - docs: add another link
 12:40
augustus yes, you don't want to be exposing the wrong details through introspection, and I can't say as I have any particular insight as to how to balance it. But I do know some things are meaningful on a conceptual/semantic level, and you can lock in a model for that 12:42
even when implementation details later change; and of course then sometimes you have to do an incompatible v2 if your model missed something 12:43
rindolf OK, my code runs faster with Niecza.

moritz hoelzro: 'use v6;' is a sure indicator that it's Perl 6
PerlJam hoelzro: files named *.p6 or *.pm6 are likely perl 6. files that contain "use v6" or "module Foo" are likely perl 6.
hoelzro moritz: is 'use v6' pretty reliable?
moritz hoelzro: I've never seen a Perl 5 file 'use v6;' 15:27
alester But within how many lines of the first?
jnthn [Coke]: hm, I thought perl5_0.t was still epic fail...if it is workier now, it can be fudged :)
moritz so in that direction is it rather reliable
15:27 dakkar left
alester How many lines do we have to read before we hit the "use v6" 15:27
hoelzro moritz: I'm more concerned about Perl 6 files that don't include use v6
alester Also, do modules need the "use v6;"?
PerlJam hoelzro: I'd start by looking at S01:103
moritz alester: no; it's just good practise 15:28
alester hoelzro: My concern about the use v6 is that it would be first instance of us checking beyond the first line of the file for determining file-type 15:30
hoelzro fair enough 15:31
I just want --perl6 to work =(
I was thinking of adding a new ack filter for it, and not putting the perl6 rule in the defaults 15:32
15:33 imarcusthis left
masak hoelzro: there are a bunch of other heuristics you could apply to a source file to detect if it's Perl 6. 15:34
hoelzro: I bet something fairly accurate could be built just by detecting certain source substrings.
hoelzro I don't think coming up with a fairly accurate detector would be terrible, but I know that alester is concerned about looking past the extension/first line 15:35
15:35 rjt_pl left
masak oh, ok. 15:36
not_gerd .p6/.pl6/.pm6, shebang (Rakudo, Niecza, Pugs?) and use v6 in first lines sound resonable to me
masak well, if those are the limitations, then you will have to live with not detecting all Perl 6 files, I guess.
PerlJam How many lines to read into the file could be parameterized though. Let the user choose how much to read.
15:37 rjt_pl joined
hoelzro my current rules in my own ackrc check the shebang and .p[lm]?6$ 15:37
GlitchMr hoelzro: I usually use ack with perl6 with --perl
phenny GlitchMr: 09:39Z <jnthn> tell GlitchMr looks like somebody already fixed my category error
hoelzro but a lot of Perl 6 out there uses .pl/.pm =(
GlitchMr It doesn't work with .p6, but that's rare
15:38 asdf__ joined, dakkar joined
GlitchMr Also, Perl 5 programs will be valid Perl 6 programs when Perl 6 implementations will support Perl 5. 15:39
hoelzro I thought that was no longer a goal? 15:40
masak it's not a particularly easy goal, if that's what you mean :)
GlitchMr It isn't easy
But I think that Perlito already does that
15:41 hash_table joined
GlitchMr And AFAIK niecza also has experimental Perl 5 support 15:41
hoelzro very cool 15:42
not_gerd hoelzro: I'd just add a rule to detect .pl/.pm as perl6 if it starts with use v6 (or six-y shebang) and call it quits
GlitchMr Specification mentions either rakudo/niecza or pugs in shebang
hoelzro not_gerd: that would be good, but how far do we look for use v6?
PerlJam hoelzro: 10 lines
:-)
GlitchMr It isn't easy 15:43
alester hoelzro and I are discussing getting out a beta of ack 2.0
and he foolishly said "I was thinking we could get a beta out by Christmas"
to which I could only respond... 15:44
GlitchMr Which Christmas?
not_gerd hoelzro: just beyond the shebang (assuming p5/p6 ever get to interoperate) and tell your users to not do stupid things
GlitchMr lol 15:45
alester If there's one good thing about having been in development for 11 years now is that we get a good running joke out of it.
not_gerd: The problem with "stupid things" is that there is no definition of what "smart things" is at this point.
hoelzro 11 = 5 + 6!
coincidence?!
;)
alester There is no definition that "This is how you make a Perl 6 file be a Perl 6 file"
GlitchMr hoelzro: that calculation isn't valid
To begin with, 6! is 720.
hoelzro heh 15:46
15:46 imarcusthis joined
flussence it's valid in base-724 15:46
hoelzro 11 is 5 + 6.
true
GlitchMr The problem is that better than grep (usually called ack) is very popular. Surely some of users would want to do "stupid things". 15:47
alester What is stupid? 15:48
What are you calling stupid?
GlitchMr alester: I was referencing what not_gerd has said
not_gerd alester: not starting a .pl/.pm file containing perl6 with use v6
alester Yes, but what exactly is a "stupid thing"
Why is that stupid?
Is it a requirement?
15:49 cognominal left
not_gerd because for historical reasons, .pl files are invoked with perl, and that will fail unpredictably if use v6 isn't used 15:49
GlitchMr By the way, I don't think ack is better than grep. To begin with, the regexpes in ack aren't guaranteed to fast. In grep, they are guaranteed to be O(NM)
alester GlitchMr: Excellent. Then don't use it. 15:50
PerlJam heh
15:50 am0c joined
not_gerd just brainstorming, though - what about having --perl, --perl5 and --perl6 options, with the caveat that the --perl5 can have false positives and the latter false negatives? 15:50
GlitchMr But that regex performance issue affects most of programming languages with few exceptions that aren't popular anyway. 15:51
not_gerd (anyway, once we can freely intermix p5 and p6, the point becomes moot)
hoelzro well, it's not called "faster than grep"
not_gerd can dream of the future
alester Also, the "betterthangrep" in the domain name doesn't specify what "better" means
and it also doesn't refer to ack.
See also: betterthangrep.com/more-tools/ 15:52
flussence better = uses a sane regex syntax? :)
alester which are also better than grep, for some values of "better" and for some set of users.
hoelzro inouropinionanimprovementupongrep.com
alester GlitchMr: If you're hoping to engage in some sort of debate about the appropriateness of ack as your tool of choice, you're going to be disappointed.
GlitchMr Just wondering, is git grep better than grep?
alester I can't tell you without you defining what "better" means. 15:53
GlitchMr I usually use 'git grep' for searching. 15:54
not_gerd or, to make it more symmetric: --perl for both p5/p6, --perl5 and --perl6 for files that can be positively recognized as one or the other
hoelzro I get that a lot these days. 15:55
alester GlitchMr: Excellent.
hoelzro not_gerd: that's an interesting take on it; I hadn't considered that before
alester I'll also suggest that it's possible to have two different tools to choose from.
GlitchMr I like 'git grep' because 1) It works like grep 2) It ignores backup files 3) It ignores binary data 15:56
alester not_gerd, hoelzro: I'm just wary about --perl6 not being adequately reliable.
15:56 cognominal joined
GlitchMr I propose instead to not add --perl6 and adding *.p6 files detection to --perl 15:56
not_gerd alester: that was (part of) my reasoning behind having --perl catch both perl5 and perl6 15:57
masak not everyone names their Perl 6 source files *.p6
not_gerd also, what should happen with files that intermix { use v5;} and { use v6; } blocks? 15:58
alester masak: Exactly. And there is no standard yet.
masak likely never will be.
alester Perl 6 is still in footpath territory, and we're talking about paving sidewalks.
masak not everyone uses *.pl for their Perl 5 code.
GlitchMr std: use v5; print/regexp/; 15:59
p6eval std a8bc48f: OUTPUT«===SORRY!===␤Bogus term at /tmp/d866jMaCoj line 1:␤------> use v5; print/regexp/⏏;␤ expecting any of:␤ prefix or term␤ whitespace␤Parse failed␤FAILED 00:01 52m␤»
masak I've heard people insist that the .pl ending is for Prolog code.
hoelzro uses .pro
alester And maybe for them it is.
GlitchMr Actually, it is
masak personally, I tend not to use a file ending at all.
kresike bye folks
16:00 kresike left
masak I don't see why I should. from the outside, it's an executable file which happens to be a script. 16:00
GlitchMr Only .pm is magical for Perl 5.
alester GlitchMr: Except when it's Perl.
GlitchMr There is NOTHING special for .pl files
alester There is no one canonical answer.
masak indeed. 16:01
hoelzro I don't care what extension (if any) people use for Perl 6 scripts 16:05
that's up to personal taste
I would just like ack to detect them properly =) 16:06
and maybe that's not a reasonable goal at the moment
16:06 FROGGS left
alester hoelzro: That's my feeling, too. That was my understanding a year or two ago, and it still is based on today's discussion. 16:06
masak well, detecting .p6 seems like a safe bet. it's just that it's not going to capture everything.
GlitchMr Actually, it won't catch most scripts... but it will catch my December wiki 16:07
masak if you only detect on file endings, you'll never catch my files without file endings. if you detect on shebang lines, too, you're better of, since I tend to put them in.
16:07 FROGGS joined
GlitchMr The problem with .p6 is that it's practically used only for executables 16:08
Usually most of logic is in .pm files
hoelzro masak: I currently check for .p6/.pm6 and the shebang line
GlitchMr And NOBODY uses .pm6
hoelzro really?
I do...=(
jnthn STD.pm6 does :P
GlitchMr Well, ok 16:09
masak I tend to use .pm
jnthn Rakudo happily recognizes it.
masak I think .pm6 is a bit silly.
GlitchMr Official grammar does use it, but does anything else do
hoelzro and that's the issue
not that people use .pm for Perl 6
but that my technique currently doesn't register those files as Perl 6 code
masak generally, I try to avoid marking things as explicitly Perl 6. I know Perl 6 is a separate language from Perl 5, but I'm still not willing to mark everything up like that. 16:10
FROGGS masak: as long as you dont upload Perl 6 stuff to PAUSE ;o) 16:11
masak it's been done. not by me, though.
GlitchMr Actually, I think that some time ago somebody did upload Perl 6 stuff to PAUSE 16:12
masak I know both moritz and szabgab tried it.
GlitchMr But that was long time ago
masak with fairly disappointing results. documentation doesn't render right, for example.
16:12 Rix left
TimToady thinks of that as new wine in old wineskins 16:12
FROGGS ya, of course
masak I think there were other infrastructural problems.
GlitchMr But this is confusing, as PAUSE is intended to be used only with Perl 5 modules
not_gerd alester, hoelzro: see gist.github.com/4216992
GlitchMr For example, CPAN Testers could totally get confused when seeing Perl 6 module 16:13
masak GlitchMr: and yet we dearly want a CPAN eventually.
FROGGS masak: the indexer reads the module's version too, this doesnt work either
IMO CPAN is one of the greatest thing, we need that 16:14
things*
GlitchMr Isn't ecosystem CPAN already
FROGGS well, when talking about CPAN I really mean PAUSE+cpan client (panda) and search.perl.org (modules.perl.org) 16:15
we still need a few improvements 16:16
(and dists)
GlitchMr Something like CPAN or NPM registry?
FROGGS and a testers matrix
alester hoelzro: Do you have a ticket on this issue? I think that not_gerd's gist would be a good start of one as far as ideas.
rurban How do you guys get the nice formatting in wordpress blog posts? Pasting from MS Word?
FROGGS GlitchMr: NPM?
hoelzro alester: good idea! I do!
16:16 cognominal left
GlitchMr FROGGS: npmjs.org/ 16:16
alester But really, just bringing up CPAN points to the issues that are much bigger than ack. 16:17
How does PAUSE handle Perl 6 files?
GlitchMr It doesn't.
We are using perl6 ecosystem for now.
But this isn't even close to CPAN
not_gerd rurban: I used markdown to write the article and just copied the generated HTML to WP
jnthn just wrote the post straight in the WP editor 16:18
GlitchMr By ecosystem, I mean github.com/perl6/ecosystem/blob/ma.../META.list
rurban hmn, jonathans posts are specially nice
FROGGS alester: the main problem is that you can make a distribution (a bundle with a specific version) yet, so even having an upload portal wont help that much
cnt*
cant*

FROGGS a bit outdated
flussence that guy needs a slap for domain-squatting. 16:28
masak it's no fun to have a page that was last updated in 2010 make statements about the usability of Perl 6.
flussence: what, why? he is developing a project called cpan6.
pmurias it seems tempting to reuse cpan testers by making perl6 modules put on cpanm use Rakudo::Star to run their tests ;)
16:29 Celelibi left
flussence masak: yeah, the site *says* it's under development. Doesn't mean it is though. 16:29
BinGOs cpanm != CPAN
alester posts an orange diamond "Under Construction" animated GIF
masak flussence: that's not what I meant. I meant it's an appropriate domain name for a project with that name.
flussence: it hardly qualifies as "domain squatting" in any reasonable sense of the word. 16:30
rurban MarkOv would certainly be happy to use rakudostar to run the tests
Someone just should kick his lazy ass, esp. if he/she is in the neitherlands.
BinGOs pmurias: and ironically cpanm is the one CPAN client that doesn't send CPAN tester reports.
16:31 cognominal joined, Celelibi joined
flussence it just seems wrong (and rude) to grab a site like that to ride on the perl 6 name, while contributing nothing in the other direction. 16:32
alester flussence: Or maybe someone nicely ask him about it.
The guy who registered rakudo.org was pretty cool about letting the project use it. 16:33
rurban Wellm his plan was to create a pause6 and cpan6, but then he went the xml way...
cpan6.org/papers/cpan6-impl.pdf
timotimo hah, "the neitherlands"

rurban converting all that mess to YAML and then it could be doable.
not_gerd that's where you get when you take a wrong turn on your way to neverland
flussence YAML? Why not $three-million-formats.pick()?
timotimo is the logo from the left composed of bits of the ubuntu logo? >_>
moritz I think everything on cpan6.org is older than Ubuntu :-) 16:35
rurban I'm sure he would love to get cpan6 functional 16:36
GlitchMr For me Perl 6 should support multiple module versions
masak I dislike when people talk about "slapping" or "kicking" someone who went as far as writing a specification and a web page for their project. feels a bit lacking in appreciation.
GlitchMr Just like Node.js already allows.
rurban masak: yes, sorry. I regret it

I just think that his design as it stands is pretty far away from what Perl 6 needs. 16:38
rurban we have github nowadays, we just need an index
flussence masak: you're right. I shouldn't care. There's people paying for the site's development, they can care instead :)

not_gerd bye, #perl6
16:39 not_gerd left
TimToady rurban: yes, though github is just one way to turn an identity into a module; the important thing is to be sure that we know how to specify identity 16:40
FROGGS GlitchMr: what exactly do you mean by "multiple module versions"? 16:41
GlitchMr For example, module A requires module B version 0.1.*. Module C requires module B version 0.2.*.
timotimo "use ACME::Cat(v0.1)"
masak timotimo: there's no need to invent syntax for this. it's all in S11. 16:42

timotimo great
FROGGS timotimo: perlcabal.org/syn/S11.html#Versioning # this tab is open on my laptop for a week now 16:43

FROGGS TimToady: what is 570 ? 16:45
TimToady line number
in the pod file
FROGGS ohh, must open with another editor to see that ;o)
TimToady the irclog will make that into a link
moritz FROGGS: check the public IRC logs; there S11:570 is a link to a specific line
FROGGS moritz: thanks
masak always nice to see new people discover the goodness of the IRC logs :) 16:47
moritz++
FROGGS ya, the irclog is pretty handy
okay, so it should work to have multiple versions... but since we dont have versions implemented it should be NYI 16:48
TimToady s/versions/identities/ is how I think of it 16:49
FROGGS ya, could be two different auth's too 16:50
TimToady a version is just an arbitrary sequential tag for (part of) an identity, while an auth is an unordered one of those
git has pretty much demonstrated you don't need versions to track identities
but for official modules, it's the identity and the readonly-ness that are important 16:51
since if a module is not readonly, it's merely a container identity, which doesn't tell you much about what the module really does
note that the filename-via-INC is container identity, hence not suitable for official modules 16:53
fine for prototyping and such, of course
but that's why S11 distinguishes official modules from unofficial 16:54
and I don't think the unofficial/official boundary should be seen at the CPANish boundary
a site should have a way to make their own modules official 16:55
just as you can gave a git repo of your own, where everything is tracked by identity
s/be seen at/be seen as existing only at/ 16:56
FROGGS I think I get what you mean
TimToady it's basically what rurban++ was getting at; the git model of identity is close to what we need for our module libraries 16:57
and name/version/auth is just a mapping to that identity 16:58
16:59 cognominal left
FROGGS I dont know what you mean by "git model of identity" 16:59
TimToady the name of anything in git is just its crypto-checksum
which stands in for the actual identity of the file, which is the actual entire file 17:02
just as value types in p6 have a .WHICH that is the value itself
the identity of any value is simply the value itself (by which I mean the abstract value that includes its type, not just the bits in memory) 17:04
rurban Go's goinstall has also a nice hackish way of installing things. First it looks for a core module of that name, and then it looks at github.
FROGGS I was thinking that we make a checksum when installing a dist to local disk to have something unique, but what you said sound like we should maybe do that when bundling dists or when uploading it to a 6PAN
TimToady modules are just immutable value types
rurban Now go has this dashboard as index: godashboard.appspot.com/ where you can submit your package 17:05
FROGGS he, most things start with "go" 17:06
17:06 hoelzro|away is now known as hoelzro
TimToady FROGGS: yes, a module must have a unique global identity from the time of submission, not just locally 17:06
17:07 fhelmberger left, cognominal joined
FROGGS will there be several 6PANs? or just one to trust? 17:07
TimToady the advantage of this view is that once you know the identity of what you want to download, IT DOESN'T MATTER where it comes from 17:08
tadzik trust pandas
(hello perl6)
FROGGS hi tadzik
TimToady so no CPANish bottlenecks
FROGGS ya
FROGGS will read something about signatures then
TimToady because it's easy to replicate a readonly data 17:09
*database
rurban golang.org/doc/articles/go_command.html
TimToady the CPAN bottleneck is actually in the assignment of identity, I suppose, since it can replicate once things are uploaded 17:10
the git approach provides a global way to calculate identity without going through a PAUSE
so it scales better
17:11 SamuraiJack joined
TimToady in a sense, github is making the same "mistake" as PAUSE, in giving you a single point of failure/constriction 17:11
FROGGS so you say I type: panda install [email@hidden.address] and there is no need for the author to package it?
TimToady well, depends on what you mean by "package" 17:13
FROGGS basically incrementing the version, and make a zipball 17:14
TimToady to the extent that a module knows its own dependencies, it can "self-package"
zipball is not an identity, it's just a collection that is convenient for transporting a bunch of objects in parallel; dependency calculation is separate from this, to my mind 17:15
17:15 birdwindupbird left
TimToady if it happens that the zipball contains the dependencies, it simplifies things, fo course 17:15
FROGGS I'm not talking about dependencies, I'm talking about making a cut and ship this thingy (the zipball) as a working piece 17:16
TimToady it won't work if you don't talk about dependencies :)
17:17 pmurias left
TimToady it's the dependencies that make it into a working piece 17:17
FROGGS well, its pandas job to get the dependencies too
my job when making a package is just to declare the deps, not to include them 17:18

TimToady I guess I'm saying it doesn't matter much where packaging is done, on the one end or the other, as long as the user ends up with the right deps 17:20
17:21 SAAMW1P joined
TimToady packaging is a convenience for transport, mostly, and it's the contents of the package that provide its identity 17:21
a bundle of value types is still kind of a value type
masak oh, most definitely. 17:22
TimToady RPMs kind of mix up those two levels, from the standpoint of how I look at it
17:23 FROGGS_ joined
TimToady sort of the same problem as makefile dependencies that are not emergent from the properties of the files themselves 17:23
17:24 FROGGS left
TimToady it's installing a higher-level dependency to stand in for a bunch of low-level dependencies, which has both advantages and disadvantages 17:25

lue I've come to the conclusion now that the best way to separate the src/core is to give rakudo the gift of gcc's -c flag (at least the "oh don't worry, those stubbed classes, they're defined in another file" part) 22:39

bbkr_ looks like bug to me
sorear if only it were that simple 22:42
lue The idea is to to run each file in src/core through perl6 in a way that it won't complain about as-of-yet undefined classes etc. (hence me thinking of gcc -c and multi-file C/++ projects). Then concatenate the compiled files and do the normal PIR->PBC step. 22:44
I have no idea how difficult it would be to add this, but I like this idea better than trying to rearrange the code in src/core

masak Araq: nope. but welcome! :) 22:49
sorear masak: you don't remember Araq?
lue I figured. That was how I initially thought out the process, but had trouble believing "just concatenating" would work.
sorear I do
masak sorear: the name sounds vaguely familiar, yes...
masak hits the backlog
oh, yeah. 22:50
Araq: yes, I do know who you are :)
Araq yay ... alright ... so are strings still mutable in perl 6? 22:51
sorear no.
Araq pity ... but understandable
lue (Frankly, I'm not very sure that src/core *could be* rearranged into compilable smaller bits, which is why I right now prefer what I've proposed.) 22:52
masak Araq: it doesn't really limit what you can do with them.
sorear lue: I have a new computer and it builds the niecza setting in 18 seconds 22:53
Araq well how do you explain to an outsider that the "king of strings" language called perl changed its string semantics? ;-)
sorear I would say it didn't. 22:54
Strings in perl have never been mutable, from my point of view... ;D
but we did change a lot of stuff with Str 22:55
for instance, Str always contains Unicode codepoints now, *never* octets
masak Araq: let's put it like this: what is it that you think you can no longer do now that strings are immutable?
lue should try niecza really soon. He already has mono on his computer. 22:57
Araq masak: can I do s[i] = 'A' ? sorry if the syntax is wrong, I hardly ever used perl ;-) 22:58
doy Araq: you couldn't do that in perl 5 either
masak Araq: Perl doesn't tend to view strings as arrays. 22:59
sorear what *is* different is that current perl 6 implementations use garbage collection, so they can't optimize the case of substr($x,0,1,'A'); when $x points to a Str with one reference
Perl 5 could do that in a zero-copy way if SvREFCNT($x) == 1 23:00
masak strings are item values. if you want them as a sequence of chars, you have to do .comb
sorear I mean the underlying PV refcnt
