<taw>
hello
<taw>
if I have "type t={x:foo; y:bar}" and i want to make funcion that operates on t with patter mathes depending on field x
<taw>
let f = function VALUE_OF_X1 -> pat1 | VALUE_OF_X2 -> pat2 | etc. ;;
<taw>
think that function is of foo not t
<taw>
(well, it's right ;))
<taw>
how can i do such function ?
<taw>
aa
<taw>
it works
<taw>
no bother ;)
<taw>
bye

ok, I'm sure you guys get this question all the time, but what's the best OCaml book (I have haskell experience) for a english speaking OCaml newb? (I want a printed book, not online one)
<smkl>
there are no printed books for ocaml in english
<Dalroth>
that's what I thought
<Dalroth>
makes reading on the way to work difficult :)
<smkl>
there is a book for caml light, but i'm not sure if it's useful because you already know fp
<Dalroth>
yeah, I need the hard core upper level stuff, thebasic stuff is easy, that I could learn by sitting at the computer
<Dalroth>
it's just, I can't sit at teh computer and read for any length of time, I need to be sitting on the couch or outside or anything BUT at the computer :)
<Dalroth>
how are OCaml's XML libraries? I'm getting frustrated with XSL's limitations, so what I'm REALLY doing is looking for a good FP language to replace XSL with. Haskell's XML is funky and I don't feel like writing my own parser, and I've never been a big fan on Lisp notation but will probably suck it up and do it if I have to (anything has to be better than xsl)
<smkl>
pxp should be quite complete. i'm not sure if it's very easy to use
<Dalroth>
well, it's hard to be any worse than the DOM :)
<exarkun>
it's supposed to take an Int64 and make it into a Num
<exarkun>
A seemingly simple task :)
<Dybbuk>
Dude, I am really not sure that OCaml is the best language to be doing bit-wise operations in.
<Dybbuk>
Heh. :)
<Dybbuk>
I think Nums are 30 bits. Are you taking that into consideration?
<exarkun>
Heh, probably not :) I'm trying to implement a communication protocol, though, which means sending and receiving floats in ieee754 format, so...
<Dybbuk>
Wowsa.
<Dybbuk>
Hmmm.
<exarkun>
Oh, blah.. that might be it.. I thought it would use Big_int for some reason
<Dybbuk>
You might want to check out the Marshall module. It might give you some ideas.
<exarkun>
now that you've said that I have _no_ idea why i thought that though
<exarkun>
Eh, I checked out the marshal module, it looked pretty useless :) it looks like it does all the interesting stuff with external functions
<exarkun>
this is for interoperation with other languages too though. The protocol is set, I just need to implement it :)
<Dybbuk>
Ok, well, it might be that you have to use some C functions to put things together in the end.
<Dybbuk>
High level languages are supposed to abstract the hardware representation of values...you shouldn't have to worry about them.
<exarkun>
nod.. I'd like to avoid that, but I'll keep it in mind
* exarkun
nods.
<Dybbuk>
And then, you'll have your high-endian/low-endian problem there, too, I think.
<exarkun>
yea, I'll worry about that a little later :)
<Dybbuk>
Heheh. :)
<Dybbuk>
I think you might want to do a little digging into the Ocaml source if you want a better idea of how floats and ints are stored internally.
<Dybbuk>
Also, you might want to check out cryptgs. There's a bunch of funky Ocaml bit math going on in there.
<exarkun>
cool, I'll check that out
<Dybbuk>
I think that's what it's called...if you check the Caml Humps page you'll see it under cryptography.
<smkl>
nums use big ints when needed
<smkl>
current bug is let second = add_big_int big (power_big_int_positive_int b_mid (1 lsl 4))
<exarkun>
that doesn't shift b_mid back 4 bits?
<exarkun>
poh
