  84
  85 C4::Koha - Perl Module containing convenience functions for Koha scripts
  86
  87 =head1 SYNOPSIS
  88
  89 use C4::Koha;
  90
  91 =head1 DESCRIPTION
  92
  93 Koha.pm provides many functions for Koha scripts.
  94
  95 =head1 FUNCTIONS
  96
  97 =cut
  98
  99 =head2 slashifyDate
 100
 101   $slash_date = &slashifyDate($dash_date);
 102
 103 Takes a string of the form "DD-MM-YYYY" (or anything separated by
 104 dashes), converts it to the form "YYYY/MM/DD", and returns the result.
 105
 106 =cut
 107
 108 sub slashifyDate {
 109

 111     # form xx/xx/xx[xx]

 116 # FIXME.. this should be moved to a MARC-specific module

 119
 120     # We could match on 'lib' and 'tab' (and 'mandatory', & more to come!)
 121     # But real MARC subfields are always single-character
 122     # so it really is safer just to check the length
 123
 124     return length $subfield != 1;
 125 }
 126
 127 =head2 GetSupportName
 128
 129   $itemtypename = &GetSupportName($codestring);
 130
 131 Returns a string with the name of the itemtype.

 162 =head2 GetSupportList
 163
 164   $itemtypes = &GetSupportList();
 165
 166 Returns an array ref containing informations about Support (since itemtype is rather a circulation code when item-level-itypes is used).
 167
 168 build a HTML select with the following code :

 207 =head2 GetItemTypes
 208
 209   $itemtypes = &GetItemTypes( style => $style );
 210
 211 Returns information about existing itemtypes.
 212
 213 Params:
 214     style: either 'array' or 'hash', defaults to 'hash'.
 215            'array' returns an arrayref,

1421 'random'    Select a random quote
1422 noop        When no option is passed in, this sub will return the quote timestamped for the current day
