moritz two names I haven't heard in a while :-) 06:46
TimToady at the moment they're replacing some of the gas pipeline that they decided they didn't want to blow up, and a probably working around most of the bandwidth to the Google campus :)
a bit of the same pipeline that did blow up a while back up in San Bruno; it runs about 200 meters north of our house 06:47
moritz good they decided it shouldn't blow up again :-)
TimToady they said they were testing our pipeline, and they never said it failed the test, but I notice they're replacing the pipe :)
moritz I notice such things a lot 06:48
TimToady so anyway, if Google drops off the map suddenly, either we got nuked, or a backhoe tore up the fiber
moritz toothpaste has "clinically tested" on it, but they don't say if the tests passed 06:49
sorear or what they're testing for 06:50
TimToady most of the water supply to San Francisco flows a few hundred meters south of us as well

azawawi hi 06:54
what's a good namespace for Perl 6 modules for supporting native libs e.g. libreadline, ncurses, etc... 06:55
Woodi as we speec about CA - I think it is common knowledge moust western part of it will someday goes underwater (with help of earthquake)... many peoples live on that peninsula ? or maybe Google is located right there ? 06:59
morning :)
azawawi Woodi: good morning... 07:00
sorear Woodi: that's a common joke, but I think it's common knowledge that it has no basis in reality 07:01
Woodi azawawi: libreadline probably is "internal" for rakudo. ncurses need tests
sorear it's possible most CA residents are stupider than I give them credit for, though 07:02
Woodi sorear: but Discovery...
sorear isn't that the channel that has specials on bigfoot?
Woodi but I'm glad being stupid and outjoked on that subject
azawawi sorear: so how about Net::Curl? is a good name for a nativecall module?
sorear azawawi: sure 07:03
azawawi sorear: im just thinking about namespace and how to organize them better... e.g. Net:: vs WWW::
sorear WWW::Curl might be better, since it's a web/urls thing
copy whatever perl 5 does
there's certainly no reason to mark Native in the name 07:04
azawawi sorear: thanks... i chose net::curl for now... shorter :) 07:18

jnthn japhb: The issue with qq heredocs only happens (or at least is related to the case) where the last thing in the heredoc is some kind of interpolation
xenoterracide so if +- is not a real operator... why does that not throw an exception? 09:52

10:06 perigrin left 10:07 perigrin joined
xenoterracide why are there so many DBI like modules 10:12
sorear Because nobody thought the existing ones were good enough?
xenoterracide honestly thinks that DBI, Digest, HTTP, etc need to be core libs in perl 6 10:13
10:13 perigrin left
xenoterracide but since the language is being worked on 10:13
sorear DBI and HTTP are core libs in p5 :p 10:14
xenoterracide no they aren't? or was that intended to be ironic or something?
well I guess HTTP::Tiny finally made core 10:15
10:16 PacoAir joined
sorear huh, I thought DBI and LWP *were* core modules 10:17
xenoterracide no
sorear but Module::Corelist disagrees
xenoterracide ?
sorear otoh, Digest is core (since 5.7.3) 10:18
xenoterracide orelist DBI slave-iv
Data for 2012-11-10
DBI was not in CORE (or so I think)
sorear that's what I mean, corelist disagrees with my memory
xenoterracide oh
10:18 perigrin joined
xenoterracide no they are just the most common modules ever 10:18
and about every thing that ships perl ships those
which is why they /should/ be core 10:19
10:20 PacoAir left
sorear well, I absolutely agree that Rakudo Star and whatever the Niecza distribution winds up being called should come with DBI, Digest, etc 10:22
BinGOs and a pony 10:23
xenoterracide ponies++
sorear a lot of #perl6 people use "core module" to mean preloaded in the initial namespace, like "Duration" is
and if that was what you meant I would have opposed it :p
xenoterracide but I think Perl6 is a pony
sorear anyways, sleep&
xenoterracide nah
not what I meant

xenoterracide is there a prove command? 11:36
jnthn just uses the normal prove
GlitchMr xenoterracide: just use prove 11:38
xenoterracide how do you make it recognize perl6?
GlitchMr prove -e perl6
It's as simple as that
xenoterracide ah
11:38 spider-mario joined, spider-mario left
GlitchMr Also, a small warning. -l option won't work as it modifies PERLLIB variable (Perl 6 uses PERL6LIB), but it's simple fix 11:39
env PERL6LIB=lib prove -e perl6
(or perhaps prove modifies PERL5LIB, not sure, but does it really matter?) 11:40
xenoterracide suspects alias prove6="env PERL6LIB=lib prove -e perl6" might be a good route 11:42
tadzik I started work on perl6-prove some time ago 11:43
it worked last time I tried :)
github.com/tadzik/Test-Harness
GlitchMr xenoterracide: Most likely yes 11:45
I have prove6 script too
glitchmr@strawberry ~/util> cat prove6 11:46
#!/bin/sh
env PERL6LIB=lib prove -e perl6 -r t/
But well, alias will work too
xenoterracide tadzik: you might want to check it
.perl6/2012.10/bin/p6prove: line 1: use: command not found 11:47
tadzik uh
oh
it could use a shebang :)
I'll fix it after errands&, thanks :)
GlitchMr #!/usr/bin/env perl6
Generic Perl 6 shebang
tadzik yeah
GlitchMr github.com/github/linguist/pull/275 11:48
I wonder when they will add AWK to GitHub language list ;-)
xenoterracide use v6; is required if not using module/class right? 11:49
GlitchMr It's required if it doesn't have shebang or isn't module or class.
But I should check spec 11:50
11:50 spider-mario joined
xenoterracide although the #! would invoke the correct interpreter if you let the shell do its thing... it would still be broken if you told perl to run the file correctly... (I think not being all that familiar yet) 11:51
GlitchMr It looks like it has to start with 'class' or 'module' or 'grammar' or shebang contains perl6, rakudo or niecza. 11:52
xenoterracide ah
GlitchMr But current implementation aren't implementing it yet
Or it has to contain 'use v6'
Or simply 'v6' which means 'no strict'
xenoterracide tadzik: privatepaste.com/dc543f0dca possible other problems too :/ 11:55
tadzik: I should probably mention the test fails if I use the p5 prove
GlitchMr Looks like something is wrong with p6prove
For now, using prove included with Perl 5 is better option
xenoterracide yeah, just figured I'd mention it 11:56
now to figure out why my code is fail
GlitchMr github.com/tadzik/Test-Harness/issues/1 11:57

azawawi jnthn: i have been playing with NativeCall with libcurl... thanks for writing it... so far things are great

jnthn arnsholt++ did plenty of the writing too... :)
azawawi jnthn++ arnsholt++
12:35 Psyche^ joined, sorenso joined
jnthn azawawi: Currently there's no way to pass Buf, so the only reasonable option is to pass a CArray 12:35
12:36 Patterner left, Psyche^ is now known as Patterner
azawawi jnthn: so if we have something like fread: fread(void *ptr, size_t size, size_t nmemb, FILE *stream) 12:42
jnthn: we write it as fread(CArray[Str], int, int, OpaquePointer) , right?
star: use NativeCall;
p6eval star 2012.10: ( no output )
Woodi azawawi: fread(OpaquePointer, int, int, OpaquePointer) me thinks 12:44
jnthn azawawi: ah, you're trying to get the data read into the buffer? 12:45
azawawi Woodi: we need to read into a buffer to use it
Woodi I use CArray[OpaquePointer] for struct smth **s things
azawawi jnthn: yup
jnthn: that's a common thing to have in C :)
jnthn CArray[Str] won't do it because it'll expect it to work like char **strings
azawawi: Yes, that doesn't mean NativeCall supports it well yet :) 12:46
azawawi so what's the alternative or did i just hit a wall ? :)
jnthn Kinda. The current best workaround is to pass a CArray[int] sized to how much data you expect.
12:46 rindolf left 12:47 rindolf joined
azawawi and then convert the str from the CArray[int] 12:47
jnthn And that will get populated by the call.
Yeah
Buf can be useful there.
CArray -> Buf -> decode the Buf into a Str using its decode method 12:48
azawawi jnthn: thx...
i'll test it now
jnthn The upgrade path for these scenarios will probably be that you pass a Buf there, so once NativeCall supports that you can just get rid of the hack, and leave the decode to Str bit.

We received Content-Type: CArray+{IntTypedCArray}<1088505524> :) 12:51
moritz yes, CArrays don't have the nice stringifications etc. of Array
it's a very low-level type
azawawi C is low-level :)

jnthn: any rakudo LHFs waiting for me? :-)
jnthn moritz: Sink context? :)
moritz oh, and seems we have a few spectest failures
jnthn Yes, a load of tests have been added, and a couple of things are a little off... 12:53
I fixed some of it.
tadzik yeah, apparently Test::Harness can't Harness itself :)
moritz jnthn: I guess I could start again looking at sink context, aye; this time I'd start with a QAST dumper :-)
jnthn moritz: On sink context, it may actually be *much* more LHF-y
azawawi jnthn: one interesting thing that we dont check if the signature is CArray[Str] and you pass a CArray[int]... 12:54
jnthn Because QAST::Want supports 'v' properly, and actually traces it properly down into nested statement nodes.
azawawi: Yeah. I actually can fix that one relatively easily these days. At the time it was gonna be a real pain... 12:55

jnthn azawawi: The integer should be part of what was placed there 13:11
GlitchMr tadzik: github.com/tadzik/Test-Harness/pull/2 13:12
jnthn azawawi: Maybe I wasn't clear enough: you're getting the C code to put the thing into what you're looking at as a int[], so there's a little work to split it up into pieces.
azawawi jnthn: true but only ct[0] is filled... the rest is the same :) 13:14
jnthn oh! 13:16
< jnthn> Kinda. The current best workaround is to pass a CArray[int]
sized to how much data you expect.
The "sized to how much data you expect" is important :)
azawawi github.com/azawawi/perl6-net-curl/...getinfo.p6
jnthn Otherwise you're passing an array wiht pretty much no allocate storage off to C, and thus it will just scribble over whatever. 13:17
yes, like that
And only the first thing has any data? 13:18
azawawi output is paste.debian.net/210112/
let me show you the getinfo.c example
jnthn r: say 186842936.base(16) 13:19

yeah i know
line 39+ 13:20
jnthn oh
char *ct;
res = curl_easy_getinfo(curl, CURLINFO_CONTENT_TYPE, &ct);
That's one more level of indirection that I'd understood!
OK, then we have an easier problem...
moritz CArray[Str].new 13:21
jnthn Pass a CArray[str] sized to 1 element, and then read it.
I thought it was a case of a char *ct = malloc(buffer_size); and then passing ct straight off...
Sorry.

moritz just write a module that exports a function that returns the values you want

GlitchMr If I would make programming language, it intentionally wouldn't have eval()... 16:53

it's just a sort of cockpit recorder, really 16:59
using position in the input as a proxy for "recent"
and backtracking resets the recorder, much like landing an airplane does 17:00
GlitchMr: eval, goto, BEGIN and such are "features of last resort" 17:01
we call them "safety valves" sometimes 17:02
they're for doing things that the language designer didn't foresee sufficiently well to provide a sane way to do it
maybe the saying should be: Sane things should be easy, and insane things should be possible. 17:03
ponbiki lol
Woodi yes, me being lazy and wanting eval ended reinventing key = value config format :)
GlitchMr Let me guess, so insane things like adding goto to Python should be possible... and those were already done - entrian.com/goto/ 17:04
I don't like eval() because it breaks many optimizations
TimToady sure, and BEGIN breaks the document model, and goto has its own issues
huf *that* is your main problem with it, not that it's horribly brittle and uncontrollable?
moritz GlitchMr: do you also dislike dynamic typing? 17:05
huf (string eval, i mean)
GlitchMr Yes, but I dislike typing like in C more.
I actually like typing like in Haskell more.
Woodi huf: perl6 syntax is controllable and self-verifing in that case :)
huf Woodi: inside a string eval? 17:06
GlitchMr Also, I don't like eval() because it breaks barrier between functions and keywords
eval can access local variables in many languages
buubot_backup GlitchMr: ERROR: syntax error at (eval 20) line 1, near "can access "
Woodi I do not like eval becouse it needs full interpreter at runtime... 17:07
GlitchMr That too
huf not having compile time at runtime is like missing a leg or 3
imho
Woodi would be realy nice to 'compile out' things to just what was used by programmer
moritz that's still possible
you just have to start with detecting use of &eval 17:08

huf but i summoned chtulhu jnthn!
moritz also note that use and require are just like eval, except a bit different :-)
huf yeah :D
GlitchMr something := eval; something(blah);
And now everything can be eval()
And you could forget about most optimizations.
huf moritz: they have a few more walls
moritz huf: right
huf GlitchMr: what if it only does that if rand > 0.5? 17:10
GlitchMr Well, it isn't pure function ;-)
huf otherwise foo becomes eval and something is just a noop.
GlitchMr (but I guess it doesn't matter)
moritz GlitchMr: sure, if you do stuff that defies optimizations, optimizations won't happen
GlitchMr: that's true in every language
Woodi I talking about Parrot threads having something called 'interpreter'. for me program should *compile* to native code and execute that :) 17:11
GlitchMr >>> blah = eval
function eval() { [native code] }
>>> blah('2+2')

JavaScript
huf Woodi: what if it cant
GlitchMr Except, JavaScript "solves" that problem by inventing "global eval" in ES5
moritz Woodi: don't judge parrot interpreters by their names 17:12
huf Woodi: what if the path you want to go down is only known at runtime?
Woodi huf: if can't then ok. but why keep all machinery all the time ?
GlitchMr But that makes stupid things, like [eval][0](something) not doing what eval(something) does
huf so you can jump back to compile time whenever you need
Woodi yes, I am speculating by 'name'...
huf: moust of the time program do-ings are known me think. outlaw runtime eval :) 17:13
jnthn The REPL bug and the eval bug with natively typed lexicals are the same underlying issue.
GlitchMr I also dislike super() function in Python 3 for being too magical.
jnthn So fixing one will fix the other...
Woodi jnthn: pls hire someone :) or few someones :) 17:14

TimToady might be overbacktracking somewhere in there
though it has to do backtracking on a [] that might be a composer 17:30
that doesn't explain why the earlier one got the wrong dba
though I guess it's basically saying that [] isn't an infix operator 17:31
on the R[] one
jnthn *nod* 17:32
Will ponder it some.
Gonna be a bit tight for tuits in the next week or two, but I want to try and give Rakudo's error reporting a shove STDwards for the December release.
TimToady it's probably not committing to the [ because infixish has to be backtrackable to term:reduce 17:33
jnthn Hm, seems HIGHEXPECT gets diddled in the lookahead too 17:36
TimToady though we might be able to throw a suppose into term:reduce to catch any panic that infixish throws
jnthn Which makes sense, and makes me worry just a bit that this mechanism is very coupled to Cursor. 17:37
(Most user grammars won't have a HIGHEXPECT.)
TimToady yes, hard to know how to generalize the concept 17:41
I wonder how Haskell's parsec handles it... 17:42
well, likely it doesn't "diddle" things in the first place, since diddling is not allowed in Haskell :) 17:44
the fact that we're using dynamic vars to emulate what should probably be ast attributes is a design smell
but we're trying to avoid copying around gobs of data every time we clone an immutable cursor 17:45
doubtless it comes back to referential issues and cons lists... 17:46

phenny japhb: 11:28Z <jnthn> tell japhb Interpolation at end of heredoc and indentation interaction bug now fixed.

17:47 nebuchadnezzar left
jnthn Well, one thing Pm and I had discussed is that Cursor currently points to orig (the original string) and target (what we're actually scanning, which is forced to be fixed width), and that we could save a word and a copy per Cursor by pulling them out into a datastructure we keep around for the whole parse. 17:47
TimToady and it's probably way overkill to be using a hash for HIGHEXPECT, if it could be cheap cons lists hanging off the ast
jnthn We also noted that other things could maybe hang off that, but the contextual nature of HIGHEXPECT makes it feel like a not so ideal candidate at first blush... 17:48
The thing that's making me worry about this is that a bunch of things seem to hinge on it 17:49
TimToady we could make cursors even cheaper to copy if we kept attrs in a cons list instead of a hash, I suspect
there are never that many of them
jnthn For example, the two terms in a row reporting is:
if $x ~~ /infix|nofun/ and not $x ~~ /regex/ and not $x ~~ /infix_circumfix/ {
attrs as in, position, target, etc?
For us Cursor is an object and at least pos is natively typed. 17:50
TimToady pos is probably usefully native
jnthn Matches have to/from as native too, I think.
TimToady but I'm thinking more of the various annotations that you don't want to back into the type of cursor
*bake
jnthn Ah, OK 17:51
TimToady we have two fighting type systems in cursor
(at least)
the "current language" vs "the current parse results"
so it gets to be MIish if we start defining classes to hold results as natives 17:52
I suppose a single level of indirection to a result struct could separate the two clashing type systems 17:53
then the result struct could have C-ish classes for native results
so basically most of the ad hoc stuff that goes into a Cursor's attr hash could be shoved down a pointer indirection to cheapen at least some of the Cursor copying 17:55
and I'm just pointing out that the pointer or pointers could point to one or more cons lists, when there are just a few attributes to carry (such as the list of expectations we hit at this point) 17:56
and adding another expectation is cheap if you just link to the front of the cons lits
*list
17:56 nebuchadnezzar joined
jnthn Hm, interesting... 17:56
TimToady hashes are not cheap to copy in FPland, I think 17:57
to use cons lists like that, one must isolate the spots that can benefit from referential integrity
immutable list tails work, but mutable ones, not so much 17:58
otoh, it kinda depends on whether the scoping of the AST matches the dynamic scoping that HIGHEXPECT is traversing 17:59
things go inside out sometimes when you are backtracking into a rule 18:00
but usually I think dynamic vars are the wrong solution, at least when you have lazy lists that can escape the dynamic scope, and call back into matchers after you've left the dynamic scope that was in effect to establing the lazy list of cursors 18:02
*blish 18:03
weird typo
'course, cons lists aren't necessarily going to be cheap on a given VM 18:04
TimToady tries again feebly to backlog... 18:05
jnthn tries feebly to take all of this in and figure out what's needed :)
