4===================

6ZOO-Kernel support translating internal messages it emits but it can
7also translate both the metadata informations stored in the ZCFG file
8and the messages emitted by the ZOO-Service itself. This document show
9how to create the files required to handle such a translation process
10for the ZOO-Services.

13ZCFG translation
14--------------------------
15
16First of all, use the following commands from your Services Provider
17directory in order to extract all the messages to translate from the
18ZCFG files :
19
20  ::
21 
22      #!/bin/bash
23      mkdir -p locale/{po,.cache}
24      for j in cgi-env/*zcfg ;
25        do
26          for i in Title Abstract;
27           do
28            grep $i $j | sed "s:$i = :_ss(\":g;s:$:\"):g" ;
29           done;
30       done > locale/.cache/my_service_string_to_translate.c
31   
32
33Then generate the ``messages.po`` file based on the Services Provider
34source code (located in ``service.c`` in this example) using the
35following command:
36
37  ::
38 
39      #!/bin/bash
40      xgettext service.c locale/.cache/my_service_string_to_translate.c -o message.po -p locale/po/ -k_ss
41
42Once ``messages.po`` is created, use the following command to create
43the ``.po`` file for the targeted language to translate into. We will
44use the French language here as an example:
45
46  ::
47 
48      #!/bin/bash
49      cd locale/po/
50      msginit -i messages.po -o zoo_fr_FR.po -l fr
51
52Edit the ``zoo_fr_FR.po`` file with your favorite text editor or using
53one of the following tools:
54
55 * `poedit <http://www.poedit.net/>`__
56 * `virtaal <http://translate.sourceforge.net/wiki/virtaal/index>`__
57 * `transifex <https://www.transifex.net/>`__
58 
59Once the ``zoo_fr_FR.po`` file is completed, you can generate and
60install the corresponding ``.mo`` file using the following command:
61
62  ::
63 
64      #!/bin/bash
65      msgfmt locale/po/zoo_fr_FR.po -o /usr/share/locale/fr/LC_MESSAGES/zoo-services.mo
66
67
68In order to test the Services Provider ZCFG and internal messages
69translation, please add the language argument to you request. As an
70example, such a request:
71
72http://youserver/cgi-bin/zoo_loader.cgi?request=GetCapabilities&service=WPS
73
74would become the following:
75
76http://youserver/cgi-bin/zoo_loader.cgi?request=GetCapabilities&service=WPS&language=fr-FR
77
78The following command may also be useful in order to pull all the translations already available for a specific language.
79
80  ::
81 
82      #!sh
83      msgcat -o compilation.po $(find ../../ -name fr_FR.utf8.po)
84      msgfmt compilation.po -o /usr/share/locale/fr/LC_MESSAGES/zoo-services.mo
