I have a PHP website that use gettext.
It has multiple text domains for specific parts of the website, and a shared text domain which holds strings used in several parts. For this I use dgettext($domain, $string).
Everything works smoothly when I get the text from the message catalogs, but I have a problem when I extract the strings. I'll explain later. Here is a working example:
- Two text domains, 'a' and 'b'. A shared text domain 'share'.
- The original strings are in English and the final output will be in French.
Code:
File Description
------------------------------------------------------------------------------------------
test_a.php Uses 'a' and 'share' text domains
test_b.php Uses 'b' and 'share' text domains
locale/fr/LC_MESSAGES/a.mo Compiled message catalog for 'a' text domain in french
locale/fr/LC_MESSAGES/b.mo Compiled message catalog for 'b' text domain in french
locale/fr/LC_MESSAGES/share.mo Compiled message catalog for 'share' text domain in french
po/a-fr.po Message catalog for 'a' text domain in french
po/b-fr.po Message catalog for 'b' text domain in french
po/share-fr.po Message catalog for 'share' text domain in french
pot/a.po Message catalog template for 'a' text domain
pot/b.po Message catalog template for 'b' text domain
pot/share.po Message catalog template for 'share' text domain
test_a.php
PHP Code:
<html><head><title>Test A</title>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
</head><body>
<?php
bindtextdomain('share', "locale/");
bindtextdomain('a', "locale/");
textdomain('a');
setlocale(LC_ALL, "fr_CH.UTF-8");
echo gettext("You are on page test A")."<br/>\n";
echo dgettext('share', "This is a common text.")."<br/>\n";
?>
</body></html>
test_b.php
PHP Code:
<html><head><title>Test B</title>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
</head><body>
<?php
bindtextdomain('share', "locale/");
bindtextdomain('b', "locale/");
textdomain('b');
setlocale(LC_ALL, "fr_CH.UTF-8");
echo gettext("You are on page test B")."<br/>\n";
echo dgettext('share', "This is a common text.")."<br/>\n";
?>
</body></html>
po/a-fr.po
Code:
msgid ""
msgstr ""
"POT-Creation-Date: 2008-10-24 01:15+0200\n"
"MIME-Version: 1.0\n"
"Content-Type: text/plain; charset=UTF-8\n"
"Content-Transfer-Encoding: 8bit\n"
#: test_a.php:12
msgid "You are on page test A"
msgstr "Vous ętes sur la page A"
po/b-fr.po
Code:
msgid ""
msgstr ""
"POT-Creation-Date: 2008-10-24 01:15+0200\n"
"MIME-Version: 1.0\n"
"Content-Type: text/plain; charset=UTF-8\n"
"Content-Transfer-Encoding: 8bit\n"
#: test_b.php:12
msgid "You are on page test B"
msgstr "Vous ętes sur la page B"
po/share-fr.po
Code:
msgid ""
msgstr ""
"POT-Creation-Date: 2008-10-24 01:15+0200\n"
"MIME-Version: 1.0\n"
"Content-Type: text/plain; charset=UTF-8\n"
"Content-Transfer-Encoding: 8bit\n"
#: test_a.php:13
#: test_b.php:13
msgid "This is a common text."
msgstr "Ceci est un texte commun."
To compile the .po files into .mo
Code:
msgfmt --output-file="locale/fr/LC_MESSAGES/a.mo" "po/a-fr.po" && \
msgfmt --output-file="locale/fr/LC_MESSAGES/b.mo" "po/b-fr.po" && \
msgfmt --output-file="locale/fr/LC_MESSAGES/share.mo" "po/share-fr.po"
When browsing test_a.php
HTML Code:
Vous ętes sur la page A
Ceci est un texte commun.
When browsing test_b.php
HTML Code:
Vous ętes sur la page B
Ceci est un texte commun.
As I said, this works.
Now the problem:
When I use xgettext to extract the strings, they are all put in the same file, regardless of any dgettext calls. I run for text domain 'a':
Code:
xgettext --default-domain=a --output-dir=pot/ --from-code=utf-8 --language=PHP test_a.php
and the string from dgettext('share', "This is a common text.") is put in pot/a.po and not an other file (ie: pot/share.po). That's it:
pot/a.po
Code:
<snip>
#: test_a.php:12
msgid "You are on page test A"
msgstr ""
#: test_a.php:13
msgid "This is a common text."
msgstr ""
For the working example above, I had to edit the message collections manually to put the 'share' string in its specific file.
Is there a way to invoke xgettext and have the dgettext strings put in the right file(s) ?? I hope I have given enough information, but ask if you need more details. I've been working on this issue for days...
PHP + gettext + multiple text domains
