Re: [Freevo-users] Freevo for people with non english speaking background ?

[David Sagnol]

Ok,

Find attached a simple program reading french or english strings
depending of the value of LANGUE variable.
The xml file discribing all the strings in Freevo could be like this:

<?xml version="1.0" encoding="ISO-8859-1"?>
<freevo>
  <string name="tvguide">
    <locale lang="en">TV Guide</locale>
    <locale lang="fr">Programme Télé</locale>
  </string>
  <string name="recordprog">
    <locale lang="en">Recorded Program</locale>
    <locale lang="fr">Programme Enregistré</locale>
  </string>
<freevo>

Using the attached class, the line 148 in tv.py
items = [ menu.MenuItem('TV Guide', action=self.start_tvguide),
would be replace by:
items = [ menu.MenuItem(xmlparse.strings['tvguide'],
action=self.start_tvguide),

xmlparse being an instance of the class ParseString. I do not check the
python gettext module but my experience with C gettext version and all
.po files is that it sounds more complicate than the proposed solution.
But I may wrong...

As usual, comments are welcomed.
