13:45 <xtrm> hello world

16:41 <TimFreeman> Does lablgtk support writing new widgets in OCAML?

17:25 <smkl> TimFreeman: see examples/tictactoe.cmo

17:26 <TimFreeman> I see. Thanks.

17:27 <smkl> i don't know why it would be useful, though

17:35 <TimFreeman> The widget I want to make is like the text widget, except you can highlight any set of characters on the screen.

20:35 <jankr_> Hi... is there any shorter way to do this? : (let f x = x + x in f)

20:36 <exarkun> is that a list comprehension?

20:36 <exarkun> oh wait nvm, parse error in my head

20:40 <smkl> (fun x -> x + x)

20:40 <jankr_> nice! thanks!

20:41 <jankr_> another question... is it possible to assign a function to an object val with access to internal vals?

20:42 <smkl> only if the val is mutable .. then it can be assigned in the initializer section

20:43 <jankr_> like object val mutable f = fun x -> x + x val mutable a = 0 method setf f1 = f <- f1 end; let x = new ... ; x#setf (fun z -> z + a) ;;

20:43 <jankr_> not during runtime?

20:43 <smkl> you can also define the "internal" values in the section before "object"

20:45 <jankr_> ok, but no way of doing what I wrote above?

20:45 <smkl> no

20:47 <smkl> that is completely impossible because the internal values are not parts of the types of the objects

20:47 <jankr_> ok... no way of making values public?

20:48 <jankr_> anyway, I can live with that :)

20:48 <smkl> nope. best approximation is to use ref as a value and make a method returing that ref

20:48 <smkl> returning

20:48 <jankr_> yet another question, to make this a high traffic evening... how does ocaml perform compared to a.e. java and c for large applications with a great deal of IO?

20:49 <jankr_> I ask because I'm sort of planning to implement an O'Caml application server... :)

20:52 <smkl> hard to say. i guess an important thing is to avoid GC when there is a lot of data that is handled by IO

20:52 <exarkun> avoid unecessary string copying :)
