Description

Provides functions to aid application developers making their software localizable. It extends the basic internationalization support provided by GLib 2.4 (and newer).

Functions

xfce_textdomain ()

void
xfce_textdomain (const gchar *package,
                 const gchar *localedir,
                 const gchar *encoding);

Sets up the translations for package .

Parameters

package	the package name.
localedir	the `package` s locale directory.
encoding	the encoding to use the `package` s translations or `NULL` to use "UTF-8".

xfce_get_file_localized ()

gchar *
xfce_get_file_localized (const gchar *filename);

Checks if theres a version of filename which is localized to the current locale. This is done by appending the full locale name to filename , separated by a '.'. If theres no file of that name, it retries using the full locale name without the encoding (if any), then without the qualifier (if any) and at last the base locale is tried. If all of those fails, a copy of filename is returned.

Parameters

filename

name of a file to look for a localized version.

Returns

path of the localized file or copy of filename if no such file exists. Returned string should be freed using g_free().

xfce_get_file_localized_r ()

gchar *
xfce_get_file_localized_r (gchar *buffer,
                           gsize length,
                           const gchar *filename);

Similar in functionality to xfce_get_file_localized(), but stores the result in buffer instead of allocating a new buffer.

Parameters

buffer	destination buffer to store the localized filename to.
length	size of `buffer` in bytes.
filename	name of a file to look for a localized version.

Returns

pointer to buffer or NULL on error.

xfce_get_dir_localized ()

gchar *
xfce_get_dir_localized (const gchar *directory);

Similar to xfce_get_file_localized(), but works on directory instead of a file.

Parameters

Returns

path of the localized directory name or copy of directory if no such directory exists. Returned string should be freed using g_free().

xfce_get_dir_localized_r ()

gchar *
xfce_get_dir_localized_r (gchar *buffer,
                          gsize length,
                          const gchar *directory);

Similar to xfce_get_file_localized_r, but works on directory instead of regular file.

Parameters

buffer	destination buffer to store the localized filename to.
length	size of `buffer` in bytes.
directory	name of directory to check for localized variant of.

Returns

pointer to buffer or NULL on error.

xfce_get_path_localized ()

gchar *
xfce_get_path_localized (gchar *dst,
                         gsize size,
                         const gchar *paths,
                         const gchar *filename,
                         GFileTest test);

paths is a ':'-separated list of pathnames, with:

%F: the filename
%L: the language string, as returned by setlocale(LC_MESSAGES, NULL)
%l: the language component of the language string
%N: application name

Example paths: /usr/local/lib/%L/%F:/usr/local/share/%N/%l/%F

Parameters

dst	destination buffer.
size	size of `dst` in bytes.
paths	the path
filename	the filename
test	test

xfce_locale_match ()

guint
xfce_locale_match (const gchar *locale1,
                   const gchar *locale2);

The locale is of the general form LANG_COUNTRY.ENCODING @ MODIFIER, where each of COUNTRY, ENCODING and MODIFIER can be absent.

The match is done by actually removing the rightmost element one by one. This is not entirely according to the freedesktop.org specification, but much easier. Will probably be fixed in the future.

Parameters

locale1	the current locale value as returned by setlocale(LC_MESSAGES,`NULL`).
locale2	the locale value to match against.

Returns

an integer value indicating the level of matching, where the constant XFCE_LOCALE_FULL_MATCH indicates a full match and XFCE_LOCALE_NO_MATCH means no match. Every other value indicates a partial match, the higher the value, the better the match. You should not rely on any specific value besides the constants XFCE_LOCALE_FULL_MATCH and XFCE_LOCALE_NO_MATCH, since the range of returned values may change in the future.

Since: 4.2

Types and Values

XFCE_LOCALE_FULL_MATCH

#define XFCE_LOCALE_FULL_MATCH 50

XFCE_LOCALE_NO_MATCH

#define XFCE_LOCALE_NO_MATCH 0
