[Coke] ok. crontab problem with running pugs: i run it from the command line, it fails almost nothing. from cron, several hundred more. 00:13

bbkr good morning 07:17
how to write tests for LTA error messages like this one: github.com/perl6/roast/blob/094220...ray.t#L338 to avoid conflicts with other implementations?
moritz the first step is to determine what the proper error message would be 07:24
then define an exception class for it
07:24 brrt joined
moritz and then use throws_like from Test::Util 07:24
the current tests are certainly wrong
my class X::Index is Exception { has $.aggregate; has $.index; method message() { "Cannot index {$.aggregate.^name} with $.index" } } 07:26
or so 07:27
bbkr every error should throw some kind of exception? 07:28
07:29 prettyrobots left
moritz some should fail(), some should throw exceptions 07:29
I'm not quite sure when to do what, but it's usually OK to start with die()
and yes, all errors (except internal errors) should end up being of a proper exception class 07:30
07:30 prettyrobots joined
bbkr this example above throws X:AdHoc - is is something temporary (that should not be put in test)? 07:30
moritz X::AdHoc is what you get when the throwing location doesn't pass an Exception to &die 07:31
so, not something you should test for in this context
(and the error message is certainly wrong)
probaly needs an if nqp::isnanorinf($index) { ... } check at some point 07:32
bbkr I'm restoring ticket and removing this test then. Sorry about trouble niecza guys. 07:34
moritz (allowing proper tests for such conditions is the reason I did the whole typed exception stunt. It's still hairy) 07:35

hoelzro does NativeCall only use *.bundle on OS X?
bbkr moritz: exception thing makes perfect sense in multi-implementation-world 07:40
geekosaur why would it use it elsewhere? os x and nextstep are the only oses that use *.bundle
bbkr hoelzro: yes, there is issue filled about it - github.com/jnthn/zavolaj/issues/7 07:41
hoelzro geekosaur: what I mean is will it also use *.dylib
bbkr: thanks
masak goede morgen, #perl6 07:42
bbkr hoelzro: if you want to use dylib you have to hardcode like here: github.com/bbkr/GeoIPerl6/blob/mas...eoIP.pm#L7
hoelzro unfortunately, it's DBIish that's doing the native stuff, not me =( 07:44
bbkr moritz: how about Failures - will they be also replaced by exceptions so I should avoid writing tests like: github.com/perl6/roast/commit/c1c8...8d0e6fd94b ? 07:45
07:45 fhelmberger joined
moritz bbkr: not replaced 07:47
bbkr: but you can write something like
throws_ok 'use fatal; "foo".substr(4)', X::Str::Substr::EOS; or so 07:48
or you can get at the failure's exception with .exception 07:49
bbkr Test::Util is not included in Rakudo yet? 07:50
tadzik r: use Test; "foo".substr(4); say "alive"; { use fatal; throws_ok { "foo".substr(4) }, X::Str::Substr::EOS; }; say "alive2"

hoelzro well, I'm passing %params to new of a class

moritz I guess it should work, but we'd have to ask jnthn++

hoelzro moritz: btw, which synopsis covers :=?
moritz but if you then use %.h inside the class, it might call the .hash method
so it's safer to use a scalar attribute

hoelzro =(
jnthn Doing Associatve doesn't imply anything about flattening in hash context. It just means you support at_key. 10:04

hoelzro so my %hash = Class.new coerces the RHS to a Hash?
10:06 Guest6173 joined
jnthn No 10:06
It doesn't coerce it anywhere
Storing into a hash first puts the list of things being assigned into flattening, eager context. 10:07
It then goes through them. If it sees anything that is ~~ EnumMap, it flattens that in. If it sees a Pair or Enum object, it will use it as a key/value pair. For anything else, it expects there to be a key followed by a value. 10:08

daniel-s_ :) hi p6eval
so, I have never been that interested in how compilers work, but I have recently had a little project in which I need to read a particular file format 12:26
I tried the first time, basically it's really long and has a whole bunch of really complicated loops and regular expressions
...then I read a book on compiler design :) 12:27
moritz :-)
daniel-s_ when you have created tokens and you're parsing the tokens, what goes on the non-leaf nodes?
that's where I'm stuck, I'm trying to write a recursive loop that creates the syntax tree. From there I'm pretty much set 12:28
tadzik are you reading "Let's Build a Compiler", by any chance?
daniel-s_ should I be creating a new token that I call something like, "expression token"
moritz daniel-s_: with "token", do you mean the piece of text just read, or a piece of the AST? 12:29
daniel-s_ Fundamentals of Compilers, an introduction to computer language translation
Karen A. Lemone 1992 0-8493-7341-7
Before I started reading I thought it was going to be a horrible scary book (I never did computer science) 12:30
but it's actually really simple and easy :)
12:30 zhutingting left
moritz maybe I should read it too :-) 12:30
daniel-s_: there are different approaches, so without a bit more context it's hard to answer the question 12:31
the first is the classical compilation in phases
first you tokenize the whole file
daniel-s_ I started this morning, I thought I would read it through (it's only 150 pages) then write my interpreter, but I keep getting impatient and will read a chapter, implemented, get stuck, then read the next chapter and get unstuck
moritz then you create a parse tree from the token
and then the AST from the parse tree 12:32
daniel-s_ that's where I'm stuck (parse tree from tokens)
12:32 rafl left
moritz and then the IR or assembler or from the AST 12:32
daniel-s_: there are basically two approaches, recursive descending parsing
daniel-s_: or using a tool like bison/yacc 12:33
recursive descending is probably easier to understand
there, you start with a top rule
like 'program'
12:34 rafl joined
moritz and if a program is just a list of expressions, you just call 'expression' until all of the tokens are consumed 12:34
and collect the return values from all 'expression' calls in an array, and return it
cpansearch.perl.org/src/MORITZ/Math.../Parser.pm is a recursive descending parser for mathematic expression 12:36
cpansearch.perl.org/src/MORITZ/Math...r/Lexer.pm for the tokenizer 12:37

masak I won't have time to ram D2 into the July release, I'm afraid. but I'll probably get started on it before Thursday.
moritz so, we downgrade it to 4.4.0 ?
pmichaud yes, back it down to 4.4.0
unless there's something in 4.6.0 that we think we need
moritz fwiw after 4.6.0 there'll be the io_cleanup merge (I hope), to which I plan to upgrade nearly immediately
pmichaud I'll try to get the release guide updated with this; but if not -- masak++ you know what to do :)
will the io_cleanup merge involve patches to rakudo/nqp ? 14:29
moritz yes
pmichaud okay, so we'd have to bump then.

sirrobert that clarified it. Thanks all. I'll put a up a blog post about it in a min. 16:13
thou tadzik: do you have an example of any module that includes C code as part of it (to be used via NativeCall)? or an idea of how you think such a thing would be structured and built, or what tools need to be developed to make that happen? I just started playing w/ a simple Term::Curses module, and need some helper functions to work around macros in the curses API.... I have it working, but just with is native('term-curses.dyl 16:17
ib') and manual build of the lib.
maybe it's premature to worry about packaging on that kind of thing 16:18
arnsholt AFAIK we don't have any modules that have C code in them as well 16:21
How complicated are the macros you're replacing?
You might be able to replicate them with pure Perl code
16:25 prettyrobots joined
thou arnsholt: the problem i have is that the curses api does stuff like: getyx(WINDOW *, int y, int x). this is a macro that uses the opaque WINDOW * object to get out the values, and stores them into y and x (notice those are not pointers -- the macro assigns directly) 16:26
so void term_curses_getyx(WINDOW *win, struct Point *p) { getyx(win, p->y, p->x); } 16:27
16:28 MayDaniel_ joined
thou i'm using a class Perl is repr('CStruct') to get the values back out 16:28
i can't avoid the macro, afaik, the curses api doesn't provide a non-macro way to (portably) extract those values
16:30 mucker joined
geekosaur it doesn't. it's a mess 16:30
16:32 PacoAir left
thou this is kind of getting off-topic, but, "Also, ncurses meets the XSI requirement that every macro entry point have a corresponding function which may be linked (and will be prototype-checked) if the macro definition is disabled with #undef. " 16:32
but i couldn't seem to get that to work (i tried stuff like sub getyx(OpaquePointer, int is rw, int is rw) (to try to say "I'm passing a pointer-to-int"), but it (not surprisingly, to me at least) segfaults 16:34
[Coke] needs to add the timings to the test runs. I'd be interested to see how long pugs takes to pass its 40 16:35
% of rakudo's tests.
s/see/track/ 16:36
arnsholt thou: Oh! I see. Yeah, I've no good ideas then 16:47
But if the signature is void getyx(WINDOW *, int *, int*) it might be better to make it sub getyx(OpaquePointer, CArray, CArray) and use one-element arrays 16:48
I'm not at all certain that int is rw is supposed to work 16:49
Speaking of #undef and such, seeing how you're using (under the hood, that is) dlopen and friends to get at the symbols, the function equivalents should be directly available without any further hackery 16:50
Also, given that curses is vaguely objecty, you might want to look at the CPointer REPR 16:52
thou arnsholt: yes, i was considering using CPointer. it turns out the doc i was reading is wrong, not *all* of the macros have function implementations. from curses.h: /* These pseudo functions are always implemented as macros: */ #define getyx(win,x,y) 16:54
there *is* a non-portable function available in ncurses, so i could just cheat and use that. thanks for the tip about single-element CArray, that makes sense
16:55 zhutingting left
PerlJam seems like zavolaj should provide handy aliases for the one-element CArray of int and str 16:55

bbkr I'll reverse test logic and fudge it for Rakudo and Niecza
sorear good point, I wasn't even looking at the test itself :D
moritz: saying that Rakudo has the nicer error message implies that Niecza has an error message at all, which I would dispute :D
moritz sorear: it prints something in the case of an error, so I'd call it an "error message" :-) 20:23
bbkr also RT should be reopened here, am I right?
moritz yes

rurban: can you paste the output from running ./perl6 -Ilib t/spec/S32-io/IO-Socket-INET.t please?
erm, better to nopaste :-)
rurban cygwin has only some filespec tests and dash-e.t failing
sure. just redoing it
[Coke] masak: pugs spectesting back up and running. Now we just need someone to write some haskell. ;) 20:26

[Coke] your mention of grant reminds me to poke pmichaud for a grant report. 20:29
masak I was just bitten by a logical bug -- sprintf not matching the number of args to the number of directives.
20:29 bruges_ left
masak feels like the compiler is doing less than it can there. 20:29
partly because sprintf encodes a sublanguage as a dead string. 20:30
like Perl 5 does with regexes.
[Coke] "we completely rewrite regular expressions, but leave sprintf as is?"
masak :)
flussence is there any prior art we can steal? :) 20:31
masak there are several forces in play here. one the one hand, sprintf suffers from its first argument being a dead string.
20:31 bruges joined
flussence (preferably prior art that can be used in double-quoted strings without causing insanity) 20:32
masak on the other hand, it's a very convenient and useful encoding of formats, and the mixing of constant string values and directives is *deliberate* and actually the very reason we use sprintf.
but to me it looks like a slang now that I think about it.
not a string.
well, hm. 20:33
in Druid I actually built strings and passed them to sprintf. I couldn't do that (as easily) with a slang. maybe.
dalek ast: 506d0a5 | (Pawel Pabian)++ | S12-class/attributes.t:
initialization of class attribute using .= should work

IRC discussion in RT #74850
masak but most of the time I just have a constant string.
[Coke] I don't know what you mean by dead string. 20:34
seems like writing a grammar for the sprintf format would be an obvious implementation. 20:35
rurban nopaste.snit.ch/148450 cygwin fails
[Coke] (except that passing what we have to sprintf() is obviouser)
moritz rurban: which rakudo branch are you on? 20:36
rurban moritz: nom
flussence
.oO( U+1F4A1! )
jnthn moritz: When was .encoding added?
[Coke] hurls www.tcl.tk/man/tcl8.6/TclCmd/format.htm for a slightly-different-from-ANSI version of sprintf.
rurban $ g br -r origin/HEAD -> origin/nom 20:37
jnthn moritz: could the earlier drop to an earlier Parrot version have caused it?
rurban parrot did not merge the io_cleanup1 branch yet
jnthn Aye, but the .encoding method could still have been a recent addition. 20:38
masak [Coke]: dead string as opposed to a sublanguage, which is syntax-checked with the rest of the program. even Perl 5 regexes are syntax-checked. not so sprintf format strings. 20:39
diakopter you might use a new quote mechanism 20:40
rurban PERL6LIB=lib:. ./perl6 t/spec/S06-routine-modifiers/lvalue-subroutines.rakudo runs only 8 tests, not 14
moritz d0dc2d33d0a5eabc1a781b52c253d1f1d85d0a61 in branch parrot-iocleanup1 20:42
+ $PIO.encoding(nqp::unbox_s(PARROT_ENCODING(self.encoding)));
looks like it might have caused that issue
rurban And one more issue: "SEGV in Parrot_CallContext_get_pmc_keyed_int" (61 lines) at nopaste.snit.ch/148452 20:43
moritz but, I have no idea if/how that commit made it into rurban++'s nom branch
20:43 tyatpi left
moritz rurban: what does 'git describe nom' say on your rakudo repo? 20:43
rurban Ooh. I see the problem. my fault. sorry 20:44
g diff origin/nom.. has this line added. $PIO.encoding(nqp::unbox_s(PARROT_ENCODING(self.encoding)));
moritz rurban: I'm relieved that I didn't mess up nom then :-) 20:45
rurban I'll redo all the rakudo tests now. I'm relieved also. Sigh
moritz it won't have any effect on non-socket tests
[Coke] masak: if I am bored I'll write up a grammar that matches the tcl one I sent. 20:46
moritz wow, that segfault is what, 4 nested runloops deep?
masak r: my %h = foo => 1, bar => 2; .say for (%h ==> map { .value })

p6eval rakudo 1fe39c: OUTPUT«Cannot call 'map'; none of these signatures match:␤:(&code, *@values)␤␤ in block <anon> at /tmp/B0n2MdXjsl:1␤␤»

p6eval rakudo 1fe39c: OUTPUT«===SORRY!===␤CHECK FAILED:␤Undefined routine '&key' called (line 1)␤»
masak oh!
rurban I count even 5
masak r: say key (foo => 1)
p6eval rakudo 1fe39c: OUTPUT«===SORRY!===␤CHECK FAILED:␤Undefined routine '&key' called (line 1)␤»
masak that explains it.
why is 'keys' a builtin sub but not 'key'?
flussence just throwing some ideas around: gist.github.com/3124942 20:48
moritz masak: because p5 has hashes, but no pairs

masak I've often felt that we builtinize too few of them. never felt that we builtinize too many. 20:50
20:50 MayDaniel left
moritz feels the exact other way round 20:51
masak it's a good thing we're both on the project, then. :)
moritz too few masaks and too many moritzes
or so :-)
sorear the problem with methods is that it's very difficult for the optimizer to statically prove that they haven't been overridden
20:51 not_gerd left
masak aye. 20:52
sorear "I guuess that makes me masak"
moritz well
masak I'm not favoring one over the other.
I'm saying we're not being very consistent about which methods we builtinize.
moritz in rakudo, we usually re-dispatch the sub form to the method form
so we don't get any speed benefit from the sub form
rurban with pair you mean something like a cons cell?
moritz rurban: yes
r: say (a => 1).WHAT 20:53
p6eval rakudo 1fe39c: OUTPUT«Pair()␤»
sorear but perl 6 does _not_ use cons lists
moritz ... except when you do :-)
masak unless you build them from Pairs.
rurban I see. Maybe I can add that to the coretypes of hash with fixed-size 1. github.com/rurban/coretypes 20:54
sorear moritz: there are complicated issues with this in niecza, mostly reducing to "what dynamic scopes is &take allowed to cross?"

thou i have what seems like a bug to me, but maybe i'm not understanding scope / closure right: friendpaste.com/53MKnWboUIKj7JwCqIQ5FW 21:50
i'd expect the $!repr attribute to be available in the anonymous sub that's assigned to the FETCH param in Proxy.new 21:51
jnthn thou: Which if you'd written an anonymous sub there would be fine. :)
thou but i have to alias it, or else i get an error. in this simplified test, i get an error "Native call expected object with CPointer representation, but got something else", which is a pretty nice error
jnthn thou: But it's an anonymous method.
So it gets its own self. 21:52
thou oh, right
hmmm, why *would* i want an anonymous method?
thou checks if sub works OK
jnthn It'll work, but you probably need to take a $cont arg extra or some such
thou copied from sorear++ and from S06 without understanding 21:53
i got a segfault w/ my more complex (Term::Curses) code instead of that nice error message
sorear I suspect that Proxy.new takes methods because someone wasn't thinking quite straight when they wrote that part of S06
jnthn sorear: That is also rather possible :)
thou i see on google old (2005-era) code using -> $val { pointy block }, which is prettier imo 21:55
i wonder if it would be possible to simplify all this with something like: has $.foo :STORE({ store-func }) sugary adverbial goodness 21:59
or is that just another layer of indirection that'd be confusing
sorear I like is STORE 22:00
maybe would be better to do 'is trigger'
projects I'd like to do someday, partial list: go through the lists of Moose core and MooseX features and port as many as possible to Perl 6 22:01
'trigger' is the Moose core adverb that does what you want
thou ah, good point, i guess Moose has gotten some real-world feedback on this
mauke heh. stealing perl6 ideas back from perl5?
sorear mauke: it's more like stealing from perl6, since Moose was started by Pugs hackers 22:02
I consider everyone who works on Moose today part of the perl6 community 22:03
s/<( perl6/broader/
masak hm. not sure about that.
well, they're part of the Perl community that likes to think of Perl 6 as something serious. 22:04
