Dpkg::Gettext - convenience wrapper around Locale::gettext
The Dpkg::Gettext module is a convenience wrapper over the Locale::gettext module, to guarantee we always have working gettext functions, and to add some commonly used aliases.
When set to 0, this environment variable will disable the National Language Support in all Dpkg modules.
Specifies the default text domain name to be used with the short function aliases. This is intended to be used by the Dpkg modules, so that they can produce localized messages even when the calling program has set the current domain with textdomain(). If you would like to use the aliases for your own modules, you might want to set this variable to undef, or to another domain, but then the Dpkg modules will not produce localized messages.
- $domain = textdomain($new_domain)
Compatibility textdomain() fallback when Locale::gettext is not available.
If $new_domain is not undef, it will set the current domain to $new_domain. Returns the current domain, after possibly changing it.
- $trans = ngettext($msgid, $msgid_plural, $n)
Compatibility ngettext() fallback when Locale::gettext is not available.
Returns $msgid if $n is 1 or $msgid_plural otherwise.
- $trans = g_($msgid)
Calls dgettext() on the $msgid and returns its translation for the current locale. If dgettext() is not available, simply returns $msgid.
- $trans = C_($msgctxt, $msgid)
Calls dgettext() on the $msgid and returns its translation for the specific $msgctxt supplied. If dgettext() is not available, simply returns $msgid.
- $trans = P_($msgid, $msgid_plural, $n)
Calls dngettext(), returning the correct translation for the plural form dependent on $n. If dngettext() is not available, returns $msgid if $n is 1 or $msgid_plural otherwise.
- $msgid = N_($msgid)
A pseudo function that servers as a marked for automated extraction of messages, but does not call gettext(). The run-time translation is done at a different place in the code.
New envvar: Add support for new DPKG_NLS environment variable.
New function: N_().
Now the short aliases (g_ and P_) will call domain aware functions with $DEFAULT_TEXT_DOMAIN.
New functions: g_(), C_().
Deprecated function: _g().
Mark the module as public.
