Daenyth` using pugs, how would I make say append \r\n rather than \n? 08:30
lambdabot Daenyth`: You have 1 new message. '/msg lambdabot @messages' to read it.
08:33 Blwood joined 08:36 SS left 08:38 flokuehn joined
Daenyth` Is there any clean way to do that or would I just say "foo\r"? 08:38
08:40 rfordinal_ is now known as rfordinal
szbalint according to the spec there isn't a specific variable you can set to do it, but I guess there are different, other ways to accomplish it 08:40
Daenyth` alright
thanks
still a step up from print "foo\r\n" :P
rhr it should probably be set per-filehandle (certainly not a global var like p5). sockets should probably use \r\n by default... 08:42
Daenyth` that would be a smart way to do it
rhr something like $fh.newline("\r\n") 08:43
Gothmog_ Hm, and \r\n might not be correct, you have to use \015\012 to be sure. 08:44

Daenyth` Did "use warnings;" change? I don't seem to have warnings.pm 09:13
with pugs
or am I missing something 09:14
Blwood I am very new to perl6 but I think there's no warnings module 09:15
Daenyth` hm
alright
On some of the docs it says I can "use Perl5:foo', but when I try it fails saying it can't find the module in @*INC.. What's the best way to handle that? I didn't see any of the scripts listed modifying @*INC 09:21
Tene pugs -I/path/to/libs
is one way
Daenyth` alright, lemme try that...
pasteling "Daenyth" at 24.91.13.73 pasted "It still says that it can't find it; "use Perl5:IO::Socket"" (11 lines, 742B) at sial.org/pbot/26686 09:24
Daenyth` ohh 09:25
hmm
I think I may know why..
yup 09:26
nevermind, ignore that paste
Blwood what was the problem ?
Daenyth` there's no Socket.pm; you have to specify IO::Socket::INET
at least with my install
Blwood oh right :) 09:27
Gothmog_ And what is /usr/lib/perl5/current/i686-linux-thread-multi/IO/Socket.pm, then? :P
Blwood by the way if you want to work with sockets perl6 has some built-in functions
Daenyth` hmm 09:28
I'll look into those too then
Gothmog_: err.. >.>
Blwood you have some examples in pugs/examples/network/
Daenyth` except now it's using perl5's strict.pm
hmm
fun stuff
Gothmog_ Pugs does not parse and run Perl5 by itself, but uses perl5... 09:29
Blwood another think but not sure I think than perl6 uses strict pragma
Gothmog_ afaik
strict is on by default in Perl6. 09:30
Blwood :)
Gothmog_ Except in the command line, that is.
Daenyth` yes
Blwood Gothmog_, any idea about my Class { } problem :o ?
Daenyth` wow, the built in socket functions look nice :3 09:31
Blwood: thanks
Blwood have a look at perlcabal.org/syn/S16.html and the examples in the directory :)
lambdabot Title: S16
Daenyth` Is it ok to have a method connect in my class? 09:32
Blwood I think no
Gothmog_ Why not?
Blwood cause there's already a connect() function
Daenyth` Gothmog_: because there is a connect() builtin
Gothmog_ So, don't define a sub, but a method. 09:33
So you call $yourobject.connect()
Daenyth` oh ok
that's what I intended to do in the first place
lol
Gothmog_ And it is not ambigous.
+u
Daenyth` I think I'll just name it newconn() for better human-readability
09:34 bsb joined
Gothmog_ I would prefer connect. 09:34
Daenyth` Do I need to "connect() or die", or will the exception system handle that for me, assuming I don't provide any CATCH blocks? 09:37
Gothmog_ Blwood: What's the problem? self.drink() should work fine, afaik.
Blwood when I try self.drink in my class I have a bif error " *** Undeclared variable: ("$__SELF__",MkPad (p ..." :( 09:38
big* 09:39
Gothmog_ Daenyth`: If an exception is thrown and you don't catch it, I suppose that your program will die. But that may depend on the type of exception... read the synopsis, I don't know exactly.
Daenyth` alright
I'm also using fatal;, so that will probably force it

Daenyth` Is it breaking because of the way I'm setting $.socket? 09:49
09:51 ruoso joined, cognominal_ left
Gothmog_ I'm not sure about that, but you're using hashes the wrong way. It's %hash<foo>, not %hash{foo}. 09:51
gtg 09:52
Daenyth` ah
Gothmog_ Bye!
Daenyth` that could be it
thanks for the help
Gothmog_ np
Blwood both are correct I think
< > is just a qw like 09:53
Daenyth` hmm
nope, same error
hrm
Blwood try True instead of true ?
Daenyth` ahh 09:54
that made the error go away
now to the next one :)
09:54 chris2 joined
Blwood btw why quote $.socket = connect( "$.server", $.port ); ? :o 09:55
connect($.server, $.port) works fine
Daenyth` err
don't I want a filehandle for it?
Blwood yeah but you don't have to quote $.server 09:56
Daenyth` or something
I'm not sure
oh
habit
passing a string as a parameter I always quote it
09:57 dwave joined
Daenyth` it also occurs to me that the $bot.readline wouldn't work, because $bot itself isn't a filehandle 09:57
What's the right way to refer to $.socket? 09:58
Blwood $bot is an object not a filehandle
Daenyth` yes 09:59
but $bot's $.socket is 10:00
What's the right way to refer to it
Blwood while my $line = readline($.socket)
Daenyth` how would that work with multiple instances of the class? 10:01
that while loop will eventually be put inside the class {}, but for right now I just want to try and get what I have working
well, connected at any rate 10:02
lol
Blwood Well I am not sure, but when you do $bot.readline it is supposed that readline is a method of your object. Maybe you can write a method that return de filehandle and then readline it : / ?
the*
Daenyth` yeah.. 10:03
I'm sure there's another way to do it... oh well. My first implementation doesn't have to be stylistically perfect :P
Blwood yeah I think there's another way to do it too :(. 10:04
I have also some problems with class in perl6 (self.method ...) so I am not the best person that can help you :s. 10:05
Daenyth` method readline ($sock = $.socket) {
return readline( $sock );
}
that should do it
Blwood yeah
but why not :
method readline {
return readline( $.socket );
}
Daenyth` in case I want to specify a filehandle other than $.socket 10:06
Blwood ah okay
Daenyth` eventually it will have more than one
I'm trying to plan for it now
;)
print $sock "$message\d015\d012"; keeps making it barf 10:10
I can't figure out why

Daenyth` I'm sure it's something silly again 10:16
Blwood yeah connect() is a built-in function.
rename it and it'll work 10:17
Daenyth` you think..?
I'll try it
wolverian huh. it should work anyway.
Daenyth` hmm
I changed the name and now I get a differant error\
Gothmog_ Missing invocant is a useful error message, isn't it? 10:18
Daenyth` *** getHostByName: does not exist (no such host entry)
wolverian but, yes, it's apparently resolving connect() to the method, which is wrong
Daenyth` maybe If I did &Main::connect?
or somesuch
wolverian or something like that, yeah
Daenyth` is that the correct syntax?
wolverian it's a pugsbug, feel free to add a test for it
Daenyth` I don't know how 10:19
wolverian do you have commitbit?
Daenyth` no
I'm new to perl6
I also wouldn't know how to write a test for it 10:20

Blwood Daenyth`, so you resolved the problem ? 10:41
Daenyth` nope 10:42
that was differant code, from examples/
I'm trying to figure out where my glitch is
Blwood mm 10:43
when you dump $.server you can see that it's empty
try my $bot = Crapbot.new( nick => Crapbot, server=>%botconfig<server> ... 10:44
Daenyth` I was about to say, yeah
Blwood it should work now
Daenyth` but it should be setting it by default if I don't specify...
unless I misunderstand?
Blwood mm 10:46
you have to declare your hash in the class maybe ?
Daenyth` ok, well now it "runs"
hmm
could be scope..
I wish we had warnings.pm :/
Blwood yeah 10:47
I think if you declare your hash in the class it should work
Daenyth` well..
hmm
yeah
I'll fiddle with it I suppose 10:48
well, here's one wierd thing
oh..
hmm
hang on
10:48 agentzh_ joined
Daenyth` yeah, that's it 10:49
10:49 agentzh_ left
Daenyth` ok 10:51
it's not setting them even with the hash inside
I think it's another bug maybe
hmm
inside the class it just doesn't see any of those 10:52
Blwood :s
Daenyth` as far as I can tell anyway 10:53
well, for now I can specify things...
Blwood yeah I see that too
weird
Daenyth` has $.umodes is rw = %botconfig{'umodes'}; is the right syntax? 10:54
I mean.. should be
wolverian %botconfig<umodes> would work too, but yes, I think that should work. 10:56
Gothmog_ I don't think that {'umodes'} is a valid hash subscript, but <umodes> is.
Blwood yeah %botconfig{'umodes'} is ok, but <umodes> is better
how the eval bot work :s ? 10:57
works*
Daenyth` pretty simple really
Blwood ?eval
Daenyth` oh, you mean how do you use it
lol
Blwood yeah I know now :p

pugsbot_r17185 OUTPUT[barā¤] Bool::True
moritz_ now I try irc.perl.org 15:35
same error 15:36
TimToady @tell Daenyth` the problem is that the assignment to the hash happens after the class is parsed and so when the class is being parsed %hash<foo> isn't found. Changing "my" to "constant" fixes it because it makes the initialization of the hash happen at compile time. 15:37
lambdabot Consider it noted.
Linux\2 hi 15:38
moritz_ hi Linux\2 15:39
TimToady @tell Daenyth` but arguably it's a bug because the pseudoassignment to the has is supposed to capture a closure. that's not really pugs's fault though, because the spec used to be wrong there.
lambdabot Consider it noted.

TimToady something's screwy with the class scope, I guess 16:06

diakopter ?eval my $count; class foo { $count = 1; method s { $count = 5 and "hu$count".say }; say "hi"~self.s ; say "ho$count"; }

I have a problem
and cannot find a answer 16:40
16:40 Aankhen`` joined
bloonix I read different /proc files to collect statistics and I can read all files except some of /proc/sys/fs/... 16:40
pasteling "bloonix" at 87.78.223.119 pasted "system("cat /proc/sys/fs/file-" (12 lines, 186B) at sial.org/pbot/26700 16:41
moritz_ what's the semantics of file-nr? 16:44
btw the p6ish way to read files is 'for =$fh -> $line { say $line }'
bloonix while my $line = $fh.readline works as well. is that bad? 16:45
moritz_ readline autochomps, so the loop will exit at empty lines 16:46
moritz_ once fell into that trap
bloonix moritz_: the same result with your example
moritz_ pugs -e 'my $f="/proc/sys/fs/file-nr"; for =$f -> $a { say $a }'
2249 0 50119
bloonix it read just the first number
moritz_ funny
bloonix but I need all 3 columns 16:47
if I read /proc/uptime, /proc/stat or other files I have no problem
moritz_ if I just iterate over the file name, I get the desired result 16:48
opening it as a file doesn't work :(
bloonix moritz_: how do you do it? 16:49
moritz_ 18:46 < moritz_> pugs -e 'my $f="/proc/sys/fs/file-nr"; for =$f -> $a { say $a }'

[particle] hrmm, would `cat` be something like =(@?ARGS>>.glob).say ? 16:53
bloonix I just use cat to show how file-nr looks 16:54
[particle] yes, i'm thinking about a platform-independent cat written in perl 6. it's not directly related to your question.
spinclad well, it's the shell doing the globbing
[particle] NOT ALL SHELLS GLOB :P
moritz_ [particle]: all good shells do ;) 16:55
spinclad true. does your cat do the globbing then?
[particle] yes, but we have perl because not all shells are good.
moritz_ [particle]: but on unix it's wrong to do "manual" globbing
[particle] why is it wrong? will it double-glob?
moritz_ at least if you have files containt *, ? etc.
[particle] ick.
okay, so a unix way to do cat would be =(@?ARGS).say ?? 16:56
spinclad think so
[particle] er, make that >>.
moritz_ or just .say for =<>; 16:57
[particle] how might you conditionally call a method?
moritz_ [particle]: with 'if'?
[particle] oh, nicer. i wonder if the fish will glob for you on windows
moritz_ we should assume that, yes ;) 16:58
s/assume/spec/ ;-)
[particle] the equivalent doesn't on perl 5
moritz_ hrm
[particle] i mean, you still need to test the os
moritz_ I don't do any coding under windows... do you usually filter @ARGV through glob? 17:00
[particle] it's like if (@ARGV) { @what = ($^O eq 'MSWin32') ? <@ARGV> : @ARGV; ... }
is there a noop method i can call? 17:01
spinclad i might consult POSIX on what a shell should do, and follow that, and infuriate users of toy OS's like $MS 17:02

TimToady do you mean "var" literally as an identifier?

diakopter [particle]: depends if you're using the comb to untangle or delouse....? 17:37

I dont understand it
my $file = '/foo/bar'; for =$file ... works, but why? 19:30
19:31 stevan_ left
PerlJam bloonix: because that's what unary = is defined to do ? :) 19:31
bloonix read from a handle? 19:32
TimToady = iterates an iterator. the iterator for Str treats it as a filename, I think
bloonix but $file isnt a handle
19:32 daxim joined
PerlJam bloonix: I think you're getting hung up on one particular world view. 19:33
bloonix: think MMD.
bloonix MMD? :)
moritz_ multi method dispatch 19:34
TimToady prefix:<=>($io) doesn't have to call the same function as prefix:<=>($string)
PerlJam heh ... it would be "interesting" to type variables based on their name. 19:35
hungarian notation in the flesh!
bloonix the thing is that Im not able to readline from /proc/sys/fs/file-nr - as example - but Im not able to execute die() if "for =$file" doesnt works
I would like to work with "open() or ..." 19:36
moritz_ PerlJam: we do it all the time... if the name starts with a '@', it's an array ;)
bloonix is that a current bug?
19:36 weinig left
PerlJam moritz_: heh. 19:36
TimToady open or should work fine, as long as you use the p6 syntax and not the p5 syntax 19:37
PerlJam moritz_: yeah, I was thinking more fortranish though.
TimToady open in p6 returns the handle rather than taking it as the first arg
(doesn't have all the options of p5's open yet, either)
bloonix TimToady: but Im not able to read the file from the handle with "for =fh" because I get only the first sign
PerlJam my $io_thingy === my IO $thingy # would be "interesting" :)
TimToady =$fh 19:38
there are no bareword handles anymore

TimToady: doesn't work for me as well
bloonix it reads only "6"
moritz_ it prints only the first char that head -n1 /proc/sys/fs/file-nr prints 19:40
bloonix some files works, some not 19:41
Daenyth` What is the correct way to refer to a class variable? If class foo { has $.bar; }, how would I refer to it?
lambdabot Daenyth`: You have 2 new messages. '/msg lambdabot @messages' to read them.
Daenyth` TimToady: thanks for clearing up my bug
moritz_ Daenyth`: I think it's foo.bar 19:42
Daenyth` I didn't know about the constant keyword :)
TimToady bloonix: looks like a bug

TimToady well, at least this works: pugs -e 'say "/proc/sys/fs/file-nr".slurp' 19:43

TimToady ?eval class foo { has $.bar = 'baz'; } my $quoz = foo.new; say $quoz.bar 19:45
pugsbot_r17185 OUTPUT[bazā¤] Bool::True
Daenyth` oh
haha
TimToady Daenyth`: I wouldn't call that a class variable. "has" declares instance attributes
moritz_ Daenyth`: if you want a _class_ variable, it's class foo { my $bar }
Daenyth` I'm not very good at OO.. I'm just starting to play with it now 19:46
Can you point me at something that would help clarify the difference?
moritz_ Daenyth`: read "Objekt Orient Software Construction" by Bertrand Meyer ;)
TimToady in general, I'd avoid class variables for now; you usually don't want them 19:47
Daenyth` so use has for now?
TimToady use objects as objects, not classes
Daenyth` I don't follow
TimToady a class describes a set of objects, not an object 19:48
Daenyth` I'm pretty sure that's what I want
TimToady without a new, there is no object
and, in fact, in Perl 6 there's no type "Class" per se
Daenyth` Oh by the way, last night I found what looks like a bug. I have no clue how to write a test for it though 19:49
if you define a class method with the same name as a builtin method, it won't work 19:50
Tene Daenyth`: explain more.
Daenyth` hang on and I'll pastebin my code
actually
you know what
TimToady I thought I sent messages about that through lambdabot...
Daenyth` let me try one thing, I may be wrong.. I had a bug that I didn't know about before when I got that error
TimToady: not that one 19:51
and thank you for the help on that
TimToady what, *another* bug!!!?!??!
how can that be? :)
Daenyth` hmm strange
TimToady btw, easiest way to learn to write tests is to look at some that are already like the one you want
Daenyth` I tried using the constant thing you told me about, and it said undeclared variable 19:52
so it's still trying to figure out the class before the %botconfig
TimToady what version of pugs are you using?
Daenyth` sec
6.2.13
TimToady which revision (the rXXXXX number)?
Daenyth` where do I find that
pugs --version doesn't say 19:53
TimToady then it's probably about 9 months out of date
Daenyth` aha
I think I might have done it through cpan.. not sure
lemme check 19:54
TimToady recommend you use the latest and greatest by checking out directly from svn.pugscode.org/pugs
Daenyth` I'll uninstall this version
TimToady we were going to turn a 6.28 release several months ago but audreyt got very sick and is still recovering 19:55
and you'll want a commit bit eventually
Daenyth` how would I remove something installed via cpan 19:56
TimToady you're the daenyth of that name at gmail?
Daenyth` yes
The one and only :P
Where have you seen me before?
TimToady google 19:57
Daenyth` ?

mostly^
TimToady I'd mention you live in MA, but you'll think I'm a stalker...
Daenyth` It's information I've made no effort to hide
if it wasn't linked to my name you'd see it in my hostmask 19:59
TimToady do you prefer Daenyth or daenyth for your project handle?
Daenyth` Daenyth I suppose
I'm dissapointed about the uniqueness of my name though.. someone took it and used it on WoW 20:00
I suppose I can take that as flattery, but what's worse is someone also used my name in some slash-fic :/
that one is.. not cool

TimToady where are you finding a cvs version of pugs?
pugs is natively svn
DarkWolf84 i mean svn
Daenyth` TimToady: if I installed pugs with cpan Perl6::pugs, how would I remove it? 20:14
TimToady we tend not to install currently
what kind of OS are you on?
Daenyth` archlinux
20:14 rgs left
DarkWolf84 i'm on gentoo linux 20:14
20:14 rgs joined
TimToady I just make a symlink of pugs from /usr/bin into my build directory instead of installing 20:15
otherwise you're always running the wrong pugs...
Daenyth` mmm
20:16 REPLeffect joined
TimToady if you have the source directory, a "make uninstall" might work 20:16
Daenyth` alright..
lemme see if I do
where would cpan put that? I haven't had to remove anything from it before
TimToady otherwise go out and remove the bin/pugs lib/Pugs-6.2.13 (or rename) 20:17
probably in /usr/local
Daenyth` ok
TimToady but maybe in /usr
the locate or slocate might find them
20:18 Blwood joined
Daenyth` /root/.cpan it seems 20:18
alright
TimToady some CPAN packages are notably unsuccessful in uninstalling themselves...
don't know about this one 20:19
Daenyth` this one is also :|
so remove /usr/bin/pugs and /usr/lib/pugs-etc?
TimToady or Pugs-etc
Daenyth` yeah 20:20
TimToady then just compile a new one and run it from your build directory (or symlink it, as I said)
20:20 broquaint left, broquaint joined
Daenyth` yeah 20:21
alright
so remove /usr/lib/perl6?
DarkWolf84 no evalbot :( 20:22
Blwood Is it possible to declare a method protected/public/private ?
TimToady don't know about that; mine only contains metamorph.pl
there is no protected 20:23
20:23 ruoso left
TimToady the syntax for private methods hides them from the outside world completely, so they're completely independent of public methods 20:23
bcmb Daenyth`: you can safely remove /usr/lib/perl6 20:24
Blwood and we declare them like this : method somethin is private ?
Daenyth` yeah
installing svn
be there soon
Blwood Daenyth`, do you use debian ? 20:25
there are unofficial pugs .deb files
20:25 Casan_ left
TimToady Blwood: you can, but since it's called with $obj!foo you can just declare it as method !foo 20:26
Daenyth` arch
doesn't really help me much :P
[particle] my method i_am_a_private_method ()
TimToady not sure whether pugs implements private methods yet 20:27
since they're really just subs in disguise
Daenyth` there's no warnings.pm or anything like that, right?
TimToady warnings are supposed to be on by default
Daenyth` hmm 20:28
TimToady but pugs doesn't do everything p5 does in that regard yet
Daenyth` wierd
yeah
TimToady and warnings, unlike in p5, are really just resumable exceptions, so to suppress them in a dynamic scope you just use an exception handler
we don't have a framework for lexical warnings yet 20:29
but presumably it'll resemble p5
s
p5's
Daenyth` ugh
my ghc version is .1 version short
sigh
took forever to compile

Daenyth` It feels a lot cleaner than perl5
TimToady me too, but I'm known to be prejudiced in the matter
Daenyth` or maybe it's just the fact that I have barely any code and my coding style has improved...
DarkWolf84 for me too it's much easier
Blwood mm don't know if it's much easier
much easier becomes python :( 20:44
DarkWolf84 for classes it's easier

bloonix how can I test if a routine exists in another namespace? I search the equivalent for UNIVERSAL::can($package, $sub); 23:09
dduncan one moment ...
TimToady Daenyth`: you need .print: rather than just .print (or use parens around the arg)
Daenyth` aha, thanks
hmm 23:10
dduncan bloonix, look up .meta in Synopsis 12
or ... 23:11
TimToady the metaclass would be .HOW these days
Daenyth` TimToady: by the way, making my %hash constant didn't work. I'll just pass it as parameters to new() for now I suppose 23:12
TimToady but if it's in a package you can just use defined &FOO::bar
23:12 nperez left
TimToady you don't want "my constant", but just "constant" 23:12
Daenyth` ok, alright.. 23:13
let me try that then
TimToady constant isn't a type, it's a scope (compiler scope)
dduncan bloonix, I was going to look up how I was doing that already, but now I'm not sure that I try that anymore
Daenyth` Is there any comprehensive guide for perl5 users switching to 6? Similar to perl5's "pitfalls for perl4 users", etc
dduncan but probably .HOW is the way to go, whenever that works
not sure implemented yet 23:14
TimToady depends on MO upgrade
dduncan yes
bloonix dduncan: I hope so. until it works I use a workaround
TimToady Daenyth`: nothing comprehensive, probably several out-of-date starts
by one reckoning, the synopses are precisely that comprehensive guide 23:15
Daenyth` it's just a little difficult having it spread all over
?eval constant $foo = 'foo'; constant %bar = ( bar => "$foo" ); say %bar<bar>; 23:16
pugsbot_r17185 OUTPUT[ā¤] Bool::True 23:17
Daenyth` hrm
strange, on mine it barfs...
rhizo for %h.kv -> $k, $v { # hm, wonder why not %h.each ?
it's more in English, and goes well with .keys and .values 23:18
TimToady it's hard to have something comprehensive that is not also big
Daenyth`: that's a known bug with constant 23:19
Daenyth` alright
I'll just hardcode the string for now I suppose
TimToady in fact, I wrote the test in the test suite for that bug. :)
Daenyth` Is there any guide on how to write tests? 23:20
for a socket filehandle, I would want to declare my $sock is IO = connect(foor, bar)? 23:23
23:23 vel left
TimToady see pod in pugs/blib6/lib/Test.pm 23:23
Daenyth` thank you
TimToady probably don't want "is IO" there 23:25
"is" on a variable declaration is like a P5 tie
Daenyth` ok
TimToady if you just want to say what $sock holds, say "my IO $sock"
Daenyth` so rather I would do: has $.socket; $.socket is IO = connect()?
TimToady you don't want that "is IO" either. "has IO $.socket;" 23:26
Daenyth` ah, ok
TimToady "is" is really only for declarations of container types and ISA relationships 23:27
(pugs mostly ignores the type declarations at this point) 23:28
Daenyth` for an array that will contain only strings, would I do has Str @array;?
TimToady yes, it's the type of each element
Daenyth` alright
:)
dduncan fyi, my first cut at a complete, and successfully compiling, but otherwise untested, Perl 6 grammar can be seen at utsl.gen.nz/gitweb/?p=Language-Muld...rammar.pod 23:31
lambdabot tinyurl.com/33hvb5
23:32 lumi joined
Daenyth` TimToady: if you define a method with the same name as a builtin, it breaks 23:34
TimToady dduncan: your use of parentheses around literals seems odd
Daenyth` is that a known bug?
dduncan the parenthesis indicate a capture, afaik 23:35
TimToady paste?
Daenyth` sec
dduncan TimToady, am I not supposed to indicate captures in a grammar?
eg, what the resulting tree has in it? 23:36
diakopter Daenyth`: 'make soon' produces a ./pugs that's more than sufficiently fast... and finishes building far earlier.
TimToady I guess it's okay.
dduncan or if you mean my having some nested parens in one place, that may be due to my being unsure how many are needed
Daenyth` diakopter: what's the cost of doing that?
TimToady just most grammars end up returning typed objects so you don't need string discriminators in $0, is all... 23:37
Daenyth`: runs a little slower. I always just do the normal make myself because my machine's not too slow 23:38
pasteling "Daenyth" at 24.91.13.73 pasted "Cannot name a class method the same as a builtin" (97 lines, 2K) at sial.org/pbot/26718
dduncan with my grammar, I'm assuming that all returned object payloads will be Str, which I further process to derive an actual type
Daenyth` TimToady: that code has a lot of junk in it irrelevant to the problem
dduncan is that abnormal?
Daenyth` I can produce a cleaner example if you'd like
TimToady that's very odd 23:44
try it with "method connect () {" instead? 23:45
Daenyth` k
dduncan also keep in mind that, while I used a Perl 6 grammar there, that file is more meant to be representative ... it could very well be a grammar for Muldis D under Perl 6, but I may have to define the grammar in some other way for Muldis D hosted over Parrot, or Perl 5, or whatever ... 23:46
Daenyth` *** No compatible multi variant found: "&connect" 23:47
dduncan also, the grammar is kept simple on purpose, expecting some post-processing of the parse tree, partly so it is easy to write a parser without using any non-core modules
Daenyth` maybe declare it as multi method connect () {
?
TimToady no, yours is an ordinary method
dduncan eg, I'd want to be able to parse that Muldis D under Perl 5 using just Perl 5 regexes 23:48
TimToady it's complaining about not finding the builtins because the types don't match
Daenyth` types of what?
dduncan hence, eg, escaped quotes in strings are spelled \q rather than \', so any literal ' actually are string delimiters
anyway, what I showed you should be going on CPAN later today 23:49
TimToady type of args to the builtin connect 23:50
Daenyth` hmm
TimToady so something about server,port isn't matching up
Daenyth` is connect expecting connect( string, int )?
TimToady should be 23:51
Limbic_Region I saw a Haskell book in Borders the other day - it was on sale for $55
Limbic_Region did not buy it
Daenyth` heh
Limbic_Region besides the price, it focused on hugs not ghc
not that there should be a huge difference 23:52
TimToady print out the values of $.server and $.port before? 23:53
Daenyth` they were correct
I cut them out of the paste but I did $bot.dump right before $bot.connect
I renamed the function for now 23:54
TimToady well, try renaming your method and see if it's interfering somehow, I guess
Daenyth` it works when I rename it 23:55
on to the next bug...
99 bugs in the code, 99 bugs in the code, fix one bug, compile it again, 100 bugs in the code....
TimToady okay, something's screwed up in the MMD dispatcher then
connect() should not be calling .connect() 23:56
Daenyth` I now get *** Undeclared variable: ("$__SELF__", 15~ lines of barf) at crapbot.p6 line 61, column 32-40
line 61 is method readln
$bot.newconn; works, it's when I call $bot.readln that it dies 23:57
diakopter yes, the MMD has been broken for (50..300).any revisions
