27 The gettext module permits access from perl to the gettext() family of
28 functions for retrieving message strings from databases constructed to
29 internationalize software.
30 $d = Locale::gettext->domain(DOMAIN)
32 $d = Locale::gettext->domain_raw(DOMAIN)
33 Creates a new object for retrieving strings in the domain DOMAIN and
34 returns it. "domain" requests that strings be returned as Perl
35 strings (possibly with wide characters) if possible while
36 "domain_raw" requests that octet strings directly from functions like
37 "dgettext()".
38 $d->get(MSGID)
40 Calls "dgettext()" to return the translated string for the given
41 MSGID.
42 $d->cget(MSGID, CATEGORY)
44 Calls "dcgettext()" to return the translated string for the given
45 MSGID in the given CATEGORY.
46 $d->nget(MSGID, MSGID_PLURAL, N)
48 Calls "dngettext()" to return the translated string for the given
49 MSGID or MSGID_PLURAL depending on N.
50 $d->ncget(MSGID, MSGID_PLURAL, N, CATEGORY)
52 Calls "dngettext()" to return the translated string for the given
53 MSGID or MSGID_PLURAL depending on N in the given CATEGORY.
54 $d->dir([NEWDIR])
56 If NEWDIR is given, calls "bindtextdomain" to set the name of the
57 directory where messages for the domain represented by $d are found.
58 Returns the (possibly changed) current directory name.
59 $d->codeset([NEWCODE])
61 For instances created with "Locale::gettext->domain_raw", manuiplates
62 the character set of the returned strings. If NEWCODE is given,
63 calls "bind_textdomain_codeset" to set the character encoding in
64 which messages for the domain represented by $d are returned. Returns
65 the (possibly changed) current encoding name.
66 gettext(), dgettext(), and dcgettext() attempt to retrieve a string
68 matching their "msgid" parameter within the context of the current
69 locale. dcgettext() takes the message's category and the text domain as
70 parameters while dgettext() defaults to the LC_MESSAGES category and
71 gettext() defaults to LC_MESSAGES and uses the current text domain. If
72 the string is not found in the database, then "msgid" is returned.
73 ngettext(), dngettext(), and dcngettext() function similarily but
75 implement differentiation of messages between singular and plural. See
76 the documentation for the corresponding C functions for details.
77 textdomain() sets the current text domain and returns the previously
79 active domain.
80 bindtextdomain(domain, dirname) instructs the retrieval functions to
82 look for the databases belonging to domain "domain" in the directory
83 "dirname"
84 bind_textdomain_codeset(domain, codeset) instructs the retrieval
86 functions to translate the returned messages to the character encoding
87 given by codeset if the encoding of the message catalog is known.
88
90 Not all platforms provide all of the functions. Functions that are not
91 available in the underlying C library will not be available in Perl
92 either.
93 Perl programs should use the object interface. In addition to being
95 able to return native Perl wide character strings,
96 "bind_textdomain_codeset" will be emulated if the C library does not
97 provide it.
