=head1 NAME
C4::Koha - Perl Module containing convenience functions for Koha scripts
=head1 SYNOPSIS
use C4::Koha;
=head1 DESCRIPTION
Koha.pm provides many functions for Koha scripts.
=head1 FUNCTIONS
=cut
=head2 slashifyDate
$slash_date = &slashifyDate($dash_date);
Takes a string of the form "DD-MM-YYYY" (or anything separated by
dashes), converts it to the form "YYYY/MM/DD", and returns the result.
=cut
sub slashifyDate {
# accepts a date of the form xx-xx-xx[xx] and returns it in the
# form xx/xx/xx[xx]
my @dateOut = split( '-', shift );
return ("$dateOut[2]/$dateOut[1]/$dateOut[0]");
}
# FIXME.. this should be moved to a MARC-specific module
sub subfield_is_koha_internal_p {
my ($subfield) = @_;
# We could match on 'lib' and 'tab' (and 'mandatory', & more to come!)
# But real MARC subfields are always single-character
# so it really is safer just to check the length
return length $subfield != 1;
}
=head2 GetSupportName
$itemtypename = &GetSupportName($codestring);
Returns a string with the name of the itemtype.
=cut
sub GetSupportName{

return $$data{'lib'};
}
}
=head2 GetSupportList
$itemtypes = &GetSupportList();
Returns an array ref containing informations about Support (since itemtype is rather a circulation code when item-level-itypes is used).
build a HTML select with the following code :
=head3 in PERL SCRIPT

}
}
=head2 GetItemTypes
$itemtypes = &GetItemTypes( style => $style );
Returns information about existing itemtypes.

Find all of the image files in a directory in the filesystem
parameters: a directory name
returns: a list of images in that directory.
Notes: this does not traverse into subdirectories. See
_getSubdirectoryNames for help with that.
Images are assumed to be files with .gif or .png file extensions.
The image names returned do not have the directory name on them.

parameters: a directory name

returns: a listref of hashrefs. Each hash represents another collection of images.
{ imagesetname => 'npl', # the name of the image set (npl is the original one)
images => listref of image hashrefs
}
each image is represented by a hashref like this:

StaffImageUrl => '/intranet-tmpl/prog/img/itemtypeimg/npl/image.gif',
OpacImageURL => '/opac-tmpl/prog/itemtypeimg/npl/image.gif'

Note: I'd like to remove this somehow.
