Glib::Utils(3)

NAME
Glib::Utils - Miscellaneous utility functions

SYNOPSIS
  use Glib;
  Glib::set_application_name (Glib::get_real_name."'s Cool Program");

  print "app name is ".Glib::get_application_name()."\n";

DESCRIPTION
Here are some useful miscellaneous utilities. GLib is a portability library, providing portable utility functions for C programs. As such, most of these functions seem to violate the Glib binding principle of not duplicating functionality that Perl already provides, but there's a distinction for each one, i swear. The functions for dealing with user information are provided on all GLib-supported platforms, not just where POSIX (which provides similar information) is available, and even work on platforms where %ENV may not include the expected information. Also, the "application name" referred to by (set|get)_application_name is a human readable name, distinct from the actual program name provided by Perl's own $0.

METHODS

  string = Glib::get_application_name
Get the human-readable application name set by "set_application_name".

Since: glib 2.2

  Glib::set_application_name ($application_name)

•   $application_name (string)

Set the human-readable application name.

Since: glib 2.2

  string = Glib::get_home_dir
Find the current user's home directory, by system-dependent/appropriate means.

  list = Glib::get_language_names
Computes a list of applicable locale names, which can be used to e.g. construct locale-dependent filenames or search paths. The returned list is sorted from most desirable to least desirable and always contains the default locale "C".

Since: glib 2.6

  string = Glib::get_prgname

  Glib::set_prgname ($prgname)

•   $prgname (string)

  string = Glib::get_real_name
Get the current user's real name.

  string = Glib::strerror ($err)

•   $err (integer)

Return a string describing the given errno value, like "No such file or directory" for ENOENT. This is translated into the user's preferred language and is a utf8 wide-char string (unlike a $! string (perlvar) or POSIX::strerror (POSIX) which are locale codeset bytes).

  string = Glib::strsignal ($signum)

•   $signum (integer)

Return a string describing the given signal number, like "Segmentation violation" for SIGSEGV. This is translated into the user's preferred language and is a utf8 wide-char string.

  list = Glib::get_system_config_dirs
Returns an ordered list of base directories in which to access system-wide configuration information.

Since: glib 2.6

  list = Glib::get_system_data_dirs
Returns an ordered list of base directories in which to access system-wide application data.

Since: glib 2.6

  string = Glib::get_tmp_dir
Get the temp dir as appropriate for the current system. See the GLib docs for info on how it works.

  string = Glib::get_user_cache_dir
Gets the base directory in which to store non-essential, cached data specific to particular user.

Since: glib 2.6

  string = Glib::get_user_config_dir
Gets the base directory in which to store user-specific application configuration information such as user preferences and settings.

Since: glib 2.6

  string = Glib::get_user_data_dir
Get the base directory for application data such as icons that is customized for a particular user.

Since: glib 2.6

  string = Glib::get_user_name
Get the current user's name by whatever system-dependent means necessary.

  string = Glib::get_user_special_dir ($directory)

•   $directory (Glib::UserDirectory)

Returns the full path of a special directory using its logical id.

Since: glib 2.14
