NAME

Gimp::Features - check for specific features to be present before registering the script.

SYNOPSIS

  use Gimp::Features;

or

  use Gimp::Features qw(feature1 feature2 ...);

DESCRIPTION

This module can be used to check for specific features to be present. This can be used to deny running the script when neccessary features are not present. While some features can be checked for at any time, the Gimp::Fu module offers a nicer way to check for them.

gtk

checks for the presence of the gtk interface module.

gtk-1.1, gtk-1.2

checks for the presence of gtk-1.1 (1.2) or higher.

perl-5.005

checks for perl version 5.005 or higher.

pdl

checks for the presence of a suitable version of PDL (>=1.9906).

gnome

checks for the presence of the Gnome-Perl module.

gtkxmhtl

checks for the presence of the Gtk::XmHTML module.

unix

checks wether the script runs on a unix-like operating system. At the moment, this is every system except windows, macos, os2 and vms.

The following features can only be checked after Gimp-main> has been called (usually found in the form exit main). See Gimp::Fu on how to check for these.

gimp-1.1, gimp-1.2

checks for the presense of gimp in at least version 1.1 (1.2).

FUNCTIONS

present(feature)

Checks for the presense of the single feature given as the argument. Returns true if the feature is present, false otherwise.

need(feature,[function-name])

Require a specific feature. If the required feature is not present the program will exit gracefully, logging an appropriate message. You can optionally supply a function name to further specify the place where this feature was missing.

This is the function used when importing symbols from the module.

missing(feature-description,[function-name])

Indicates that a generic feature (described by the first argument) is missing. A function name can further be specified. This function will log the given message and exit gracefully.

describe(feature)

Returns a string describing the given feature in more detail, or undef if there is no description for this feature.

list()

Returns a list of features that can be checked for. This list might not be complete.
