i don't understand why redefinition oh methods in ocaml differs from the way java does
<CybeRDukE>
/oh/of/
<Demitar>
OCaml doesn't define classes by name.
<Demitar>
Nor does is support function overloading.
<Demitar>
A side-effect of the former is that downcasting isn't possible (well you can do it using a few tricks).
<CybeRDukE>
did you have a look at the example at the link? so in ocaml there would be only one eq-method when B is a subtype of A?
<CybeRDukE>
the only redefinition in this example is the to_string(int) method, right? and that's not different from the ocaml way, isn't it?
<CybeRDukE>
i have the same parameters an define a new body.
<Demitar>
It's not different.
<CybeRDukE>
good
<CybeRDukE>
i still do not really understand the redefiniton-difference. but overloading is clear now. thx
<karryall>
ocaml doesn't have overloading
<karryall>
so it's difficult to compare
<CybeRDukE>
yes, that's what i understodd *g*
<karryall>
but in this kind of situation B isn't a subtype of A

<Demitar>
eternite_0, that expessions should have type unit.
<CybeRDukE>
lol
<eternite_0>
But it work in the interactive interpreter
<Riastradh>
Demitar, no, not necessarily; the double semicolons indicate that he's typing it at a REPL prompt, where the type isn't necessarily unit.
<Demitar>
eternite_0, well, that makes it all the more useful, right? :)
<phubuh>
double semicolons work just as well in source files as in REPL input
<Riastradh>
phubuh, yes, but only dorki use them in source files.
<phubuh>
well, yeah
<eternite_0>
Riastradh, sorry, but what is it a "dorki" ?

eternite, 'dorki' is the plural of 'dorkus.'
<eternite>
thx
<mellum>
What's a dorkus?
<Riastradh>
It's like a dork, only with an 'us' at the end.
<Riastradh>
And thus it's a lot worse.
<mellum>
Wow, and then in plural! That's bad!
<Maddas>
haha
<phubuh>
hmm, I'm thinking about making a simple referentially transparent language that compiles to compile-time C++
<Maddas>
Heh

phubuh is being evil again.

<Maddas>
phubuh: What is your motivation?
<phubuh>
boredom
<Maddas>
haha
<Maddas>
phubuh: interesting hobbies you have :-)
<phubuh>

<phubuh>
I have to implement a Huffman decoder and file transfer for scout, but that's tedious
<Maddas>
scout?
<phubuh>
the Direct Connect client I showed you a while back
<phubuh>
(after a complete rewrite, though)
<Maddas>
Hah :)
<Maddas>
Why the rewrite?
<Maddas>
(boredom? :))
<phubuh>
pretty much :-)
<Maddas>
Heh.
<phubuh>
it was pretty poorly designed before
<phubuh>
strange dichotomies, the parser was the ugliest hack I've ever seen, etc
<Maddas>
phubuh: you should write a O'Caml -> C(++) thingy
<phubuh>
haha
<Maddas>
no really!
<phubuh>
hmm, I wonder how the code is represented in ocamlc before code generation
<Maddas>
O'Caml...
<Maddas>
:-)
<phubuh>
well, yeah :-)
<Maddas>
oh, you mean _how_. ASCII?
<Maddas>
I'm getting silly, I'll leave while I still can, talk to you later!
<phubuh>
ok, bye!

hi

proud to present a new ocaml addict

<-
<Defcon7>
:)
<phubuh>
whee!
<Defcon7>
i am really new to ocaml and functional programming, can i ask here my questions about that ?
<eternite>
You can applie "<-" only on string , array and mutable value.
<phubuh>
Defcon7: of course!
<eternite>
So what do you want to know about "<-"
<phubuh>
haha, I think he was pointing to himself :-)
<eternite>
:)
<Defcon7>
haha :)
<Defcon7>
the second is right
<Defcon7>
actually iam perplessed about ocamlopt...i compiled a small program that increments a variable from 0 to 100 with ocamlc, but when i try with ocamlopt i get a lot of assembler error messages, im just doing ocamlopt prog.ml -o prog
<phubuh>
are you on Windows?
<Defcon7>
linux debian 2.4.22 with grsec and i was compiling as root
<phubuh>
oh, that's strange
<phubuh>
could you put the actual errors some where?
<Defcon7>
since ocamlc worked i dont have thinked to that
<Defcon7>
let try :)
<Defcon7>
hehe it worked
<Defcon7>
thanks :)

im trying to use Unix.read on a stream, the string where to place what it reads should be declared in any way first ? because the compiler says "outbuffer" which obviously is the string i wish to use...
<Defcon7>
op
<Defcon7>
s
<Defcon7>
"Unbound value outbuffer"
<Defcon7>
"outbuffer"
<Defcon7>
:)
<phubuh>
yeah, you have to create it first
<phubuh>
say, let foo = String.create 1024 in Unix.read fd foo 1024 0
<Defcon7>
oh hehe
<Defcon7>
thanks :)
<Defcon7>
what about length = all, 0 is right ?
<phubuh>
I don't remember how to use Unix.read, I just made something up
<phubuh>
but the let ... in part is correct :-)
<Defcon7>
:)
<Defcon7>
ok
<Defcon7>
thanks
<Defcon7>
again about Unix.read, what i should use as length to mean "everything" ?
<phubuh>
you could use Unix.stat to find out how long it is, and use that value
<Defcon7>
tnx :)
<phubuh>
if you're just reading regular files, though, it's easier and more portable to use the Pervasives.{open_in, input, in_channel_length, close_in}
<Defcon7>
oh hehe i supposed there are something other than Unix.
<Defcon7>
tnx again :)
