[Demexp-dev] Re: Issue to use ocaml-gettext with lablgtk

Hello Sylvain,

I'm making progress, but more issues appear. :-)

done.

Ok, using GettextStub.Native the translation works!

Here is my definition of my program's Gettext module:

module Gettext = Gettext.Program
    (struct
      let textdomain   = "demexp"
      let codeset      = Some "UTF-8"
      let dir          = None
      let dependencies = Gettext.init
    end)
    (GettextStub.Native)

The .glade translation works when calling my program with:
 $ echo $LANG
 fr_FR.UTF-8

 $ ./gtk2-clnt/demexp-gtk2-client --gettext-dir build/share/locale/po/ 

A question: why do I need to give the final po/ directory? I though that
I should give "build/share/locale/", as the default for gettext-dir is
["/usr/share/locale"; "/usr/local/share/locale"].



But now working translation raises another issue: call to printf are
modified!!

For example, if at the end of a module I put:
  let _ = Printf.printf "1.0 = %3.3f\n" 1.0

I get as result when launching above program:
  1.0 = 1,000

It is obvious that the locale is taken into account for printing the
string. But this seems quite strange to me, as I do not use an _s
function in this call to printf.

This behaviour is a issue to me because:

 - I want to control when a sentence is interpreted as translatable or
   not;

 - I'm having autotest where I check hard-coded results for certain
   function calls. This behaviour breaks them.

Ok, it seems that call to "f_" and the like are working with
GettextStub.Native, so I don't need to use simultaneously
GettextStub.Native and GettextCamomile.Map.

Is it an issue to use GettextStub.Native?


Best wishes,
