02:43 <orbitz> what is the difference bewtween ocamlc.opt and ocamlopt? ocamlc.opt produces .cmo's just like ocamlc fo rme. but ocamlopt produces .cmx files

03:23 <det> .opt versions of the binaries are themselves nativecode, while .opt-less are bytecode programs

03:24 <orbitz> ohh

03:24 <orbitz> just to speed up compialation?

09:09 <munga_> anybody used the lib bz2 ? I don't undestand the signature of the read function that is : read : in_channel -> string -> int -> int -> int . The doc says that the result of the read from the inchannel will be strored in the string ... but in ocaml strings are immutable ! Am i missing something ?

09:11 <gildor> munga_: we are not yet friday, you cannot launch a troll about immutable strings in OCaml

13:44 <kaustuv> Is there something like ocaml-pcre that works on int8_unsigned bigarrays instead of strings?

13:54 <flux> I highly doubt that..

13:55 <thelema> I don't see why (other than null bytes, maybe) ocaml-pcre can't be adapted to work with bigarrays

13:56 <thelema> just a trivial addition to the interface code

14:00 <kaustuv> I think it's not difficult too, but it's below my threshold of caring enough to do the work myself...

14:08 ikaros has quit [Quit: Leave the magic to Houdini]

14:12 <thelema> derdon: trivial in the sense that someone who knew the ocaml-pcre codebase could do it easily.

14:12 <thelema> that said... I might as well get to know that codebase...

14:19 <thelema> wow, pcre-ocaml goes up in version a lot - I'm surprised it's at 6.10 now

14:23 <Camarade_Tux> maybe it somehow follows pcre itself? it's at 7.7 now but _maybe_ 7.x was mostly compatible with 6.x

14:25 <thelema> ah, he's using semver (maybe informally). great

19:31 <companion_cube> hi, i've got a small problem with batteries on debian : according to the doc, ocamlfind batteries/ocamlbuild should work, but it doesn't since /usr/lib/ocaml/batteries does only contains libs

19:35 derdon has quit [Ping timeout: 258 seconds]

19:44 <alpounet> does aaa-batteries/ocamlbuild work ?

19:44 <alpounet> or batteries-aaa/ocamlbuild

20:08 <thelema> companion_cube: batteries doesn't contain that ocamlbuild script anymore.

20:14 <thelema> companion_cube: the correct way to ocamlbuild is to use a proper myocamlbuild.ml that supports findlib packages.

20:24 <companion_cube> alpounet: there is no such package

20:25 <companion_cube> thelema: do i have to write a myocamlbuild.ml script, or ocamlbuild options and _tags files can be sufficient ?
