felher How do i compile an run a perl6 program with nom? I tried "nom --target=pir main.pl > main.pir" and then "parrot main.pir", but i get "Missing or wrong version of dependency 'src/Perl6/World.pm". Maybe i have to set some include path? 11:53
Oh, i actually tried "~/sources/perl6/rakudo_nom/install/bin/parrot main.pir" 11:54
moritz felher: I think you can only precompile modules right now, not scripts 11:55
felher moritz: oh, okay. How do i do that? Also "nom --target=pir module.pm > module.pir"? And will they be used by nom automatically? 11:56
Hm... No, it doesn't seem to be that easy :) 12:01

gfldex Woodi: can you gist the code in question? 19:31
moritz Woodi: probably that the parent class isn't known as a type name 19:32
colomon moritz: spelling is due to my great-great-grandfather. or possibly I just have trouble reading his handwriting. ;)
moritz phenny: "lebenslust"? 19:33
phenny moritz: "lebenslust" (de to en, translate.google.com)
moritz erm
I'd translate it as "joy of living"
gfldex "love of life" according to dict.leo.org
Woodi gfldex: cannot gist probably, it appears on use Module; 19:34
gfldex or "lust for life" 19:35

19:38 wolfman2000 left
Woodi yes, libs are ok 19:38
hmm, $!priv is not accesible in subclass ?
moritz of course not 19:39
anybody can subclass your classes
giving them access to your privates just because they declare themselves your children wouldn't be good encapsulation
Woodi not sure 19:41
but if it is that way then ok
moritz it's OK not to be sure; I'm sure for you too :-)
Woodi I think it limits code reuse... childrens classes are not quite aliens for me 19:42
moritz well, you can still create public accessors
Woodi public fields are for code outside hierarchy... 19:43
just thinking...
moritz I don't see the point
everybody who uses your code must stick to its API 19:44
what's the point in having two public but different APIs, one for inheritance, one for usage?
Woodi for me subclassing is just like write all code in class from the start, parents are just to share parts for siblings 19:45
moritz what's the point in forcing somebody to subclass to just to give them access to certain features? 19:46
Woodi: but that is bad encapsulation
Woodi encapsulations is for thing out of hierarchy
moritz Woodi: encapsulation means respecting boundaries, not just acting as if stuff was copied & pasted
no
encapsulation is for your own sanity
there's no need to limit your sanity when talking about subclassing 19:47
Woodi I am just in case I need parent as 'code inlining' :) 19:48
just want add few methods nothing more
eg. making field with socket public break encapsulation. or makes better design maybe, do not know 19:51

colomon excuse me, checking out CDs for sale
adu do you mean 'is's? 22:30
colomon yes 22:37
personally, I don't know what HLL::Compiler does
if you can get it working without that stuff, then it's just a matter of figuring out how to make HLL::Compiler work. If you know what I mean.
22:39 sisar left
adu when I test without HLL::Compiler I usually test without the actions, and so my problem is that the grammar is all I know how to write 22:39
HLL::Compiler is not very well documented, so I don't know what it does either
but I do know that all you need to do is build a PAST in your Actions, and HLL::Compiler can convert that to PIR 22:40
colomon I think most of the people who know how to do that are asleep right now.
