07:13 <yttrium> Trying to setup ocaml. I was installing findlib, and get this: http://pastebin.org/3922

09:58 <yziquel> hi. imagine i have "class name = object val x = 1 method y = 2 end". How can I hide x and y from appearing in the .mli file?

10:10 <wysek> what do you mean? it's you who edit .mli file

10:28 <yziquel> wysek: yes. I'm editing the .mli file. I want to have in the .ml file "class virtual name = object val virtual u : int end;;" and "class name_0 = object inherit name val u = 1 end;;". In the .mli file, I want "class virtual name : object end" and "class name_0 : name".

10:29 <yziquel> wysek: but i get a "class declarations do not match" between .ml and .mli files. "The virtual instance variable u cannot be hidden."

10:39 <flx_> I've never used virtual values :-o

10:41 <flx_> yziquel, maybe the problem is that 'val virtual u' isn't the same as 'val u'

10:41 <flx_> oh, right

10:42 <flx_> never mind, the problem might be exactly what it says

10:42 <flx_> yziquel, do you need to expose 'name' at all?

10:42 <flx_> class type name : object end class name_0 : name in the .mli

10:42 <kaustuv> yziquel: have you tried the suggestion in http://caml.inria.fr/pub/docs/manual-ocaml/manual005.html#toc24 ?

10:43 <flx_> class virtual name_virt = object val virtual u : int end class type name : object end class name_0 = object inherit name_virt val u = 1 end ?

10:49 <yttrium> er, once more: trying to setup ocaml, I was installing findlib, and get this: http://pastebin.org/3922

11:14 <yziquel> yttrium: how did you generate the findlib.cma file?

11:18 <yziquel> flx_: http://ocaml.pastebin.com/m5f993b1f I'm trying to create a swig module. As C++ objects may have different constructors, I'm trying to wrap the object in a virtual class, and create the constructors through a standard class. As you can see in the pastebin, there's a fields, underlying_cpp_object, that I wish to hide in the .mli file. In the .mli file, I need a class for each constructor, that must inherit from a virtual class

11:19 <yziquel> flx_: so I need a type class, and a type abreviation for the OCaml object.

11:19 <yziquel> flx_: that's why I feel I need to expose 'name' or 'tokenizer' in the .mli.

11:21 <yziquel> flx_: i like the example you proposed, but I also need a type abreviation of the same name as the class type.

11:21 <yziquel> kaustuv: reading your link.

11:22 <yziquel> kaustuv: thanks. type classes define type abreviations. I think that is what i need.

11:44 <yttrium> er hello again

11:44 <yttrium> i just did ./configure and make for findlib

11:45 <yttrium> yziquel:

11:46 <yziquel> yttrium: not familiar with compiling findlib by hand. If you can use the packaging system of your distribution, please do.

11:47 <yziquel> yttrium: i'll try compiling findlib manually.

11:48 <yziquel> yttrium: using version 1.2.4?

11:48 <yttrium> yes

11:50 <yziquel> yttrium: using godi is also a nice alternative to using distribution-specific packages.

11:51 <yziquel> yttrium: works fine on my end. what system are you on?

11:51 <yttrium> OS X

11:55 <yziquel> i have to go. on os x, I believe you'd have better luck using GODI.

11:55 <yttrium> I will try godi.

13:50 <palomer> peace

13:54 <jimmyb21871> Hi palomer

13:54 <jimmyb21871> Didn't get a chance to install yet

13:54 <jimmyb21871> Sorry about that... some stuff came up at work yesterday after you left

14:52 <palomer> try it out!

14:52 <palomer> !!

22:21 <raboof> i'd like to create a small script that downloads 2 RSS feeds, processes and orders their items a bit, and formats the result as HTML.

22:21 <raboof> thought it'd be interesting to try doing it in ocaml - i've done a bit of ML and Clean in the past

22:22 <raboof> for getting the data, http://projects.camlcity.org/projects/dl/ocamlnet-2.2.9/doc/html-main/Http_client.Convenience.html seemed like a good fit

22:23 <raboof> i installed netclient (from the debian package), and tried to run '/usr/share/doc/libocamlnet-ocaml-doc/examples/netclient/simple/http_get.ml'

22:25 <raboof> this starts with '#require "netclient";;', but when i type that on the 'ocaml' prompt i get "Unknown directive `require'."

22:25 <raboof> what does that mean?

22:26 <raboof> aaah, '#use "topfind";;' ;)
