 137 =head1 NAME
 138
 139 C4::Circulation - Koha circulation module
 140
 141 =head1 SYNOPSIS
 142
 143 use C4::Circulation;
 144
 145 =head1 DESCRIPTION
 146
 147 The functions in this module deal with circulation, issues, and
 148 returns, as well as general information about the library.
 149 Also deals with inventory.
 150
 151 =head1 FUNCTIONS
 152
 153 =head2 barcodedecode
 154
 155   $str = &barcodedecode($barcode, [$filter]);
 156
 157 Generic filter function for barcode string.
 158 Called on every circ if the System Pref itemBarcodeInputFilter is set.
 159 Will do some manipulation of the barcode for systems that deliver a barcode
 160 to circulation.pl that differs from the barcode stored for the item.
 161 For proper functioning of this filter, calling the function on the
 162 correct barcode string (items.barcode) should return an unaltered barcode.
 163
 164 The optional $filter argument is to allow for testing or explicit
 165 behavior that ignores the System Pref.  Valid values are the same as the
 166 System Pref options.

 262
 263 Transfers an item to a new branch. If the item is currently on loan, it is automatically returned before the actual transfer.
 264
 265 C<$fbr> is the code for the branch initiating the transfer.
 266 C<$tbr> is the code for the branch to which the item should be transferred.
 267
 268 C<$barcode> is the barcode of the item to be transferred.
 269
 270 If C<$ignore_reserves> is true, C<&transferbook> ignores reserves.
 271 Otherwise, if an item is reserved, the transfer fails.
 272
 273 C<$trigger> is the enum value for what triggered the transfer.
 274
 275 Returns three values:
 276
 277 =over
 278
 279 =item $dotransfer
 280
 281 is true if the transfer was successful.
 282
 283 =item $messages
 284
 285 is a reference-to-hash which may have any of the following keys:
 286
 287 =over
 288
 289 =item C<BadBarcode>
 290
 291 There is no item in the catalog with the given barcode. The value is C<$barcode>.
 292
 293 =item C<DestinationEqualsHolding>
 294
 295 The item is already at the branch to which it is being transferred. The transfer is nonetheless considered to have failed. The value should be ignored.
 296
 297 =item C<WasReturned>
 298
 299 The item was on loan, and C<&transferbook> automatically returned it before transferring it. The value is the borrower number of the patron who had the item.
 300
 301 =item C<ResFound>
 302
 303 The item was reserved. The value is a reference-to-hash whose keys are fields from the reserves table of the Koha database, and C<biblioitemnumber>. It also has the key C<ResFound>, whose value is either C<Waiting> or C<Reserved>.
 304
 305 =item C<WasTransferred>
 306
 307 The item was eligible to be transferred. Barring problems communicating with the database, the transfer should indeed have succeeded. The value should be ignored.

1831 C<$messages> is a reference-to-hash giving feedback on the operation.
1832 The keys of the hash are:

1834 =over 4
1835
1836 =item C<BadBarcode>
1837
1838 No item with this barcode exists. The value is C<$barcode>.
1839
1840 =item C<NotIssued>
1841
1842 The book is not currently on loan. The value is C<$barcode>.
1843
1844 =item C<withdrawn>
1845
1846 This book has been withdrawn/cancelled. The value should be ignored.
1847
1848 =item C<Wrongbranch>
1849
1850 This book has was returned to the wrong branch.  The value is a hashref
1851 so that C<$messages->{Wrongbranch}->{Wrongbranch}> and C<$messages->{Wrongbranch}->{Rightbranch}>
1852 contain the branchcode of the incorrect and correct return library, respectively.
1853
1854 =item C<ResFound>
1855
1856 The item was reserved. The value is a reference-to-hash whose keys are
1857 fields from the reserves table of the Koha database, and
1858 C<biblioitemnumber>. It also has the key C<ResFound>, whose value is
1859 either C<Waiting>, C<Reserved>, or 0.
1860
1861 =item C<WasReturned>
1862
1863 Value 1 if return is successful.
1864
1865 =item C<NeedsTransfer>
1866
1867 If AutomaticItemReturn is disabled, return branch is given as value of NeedsTransfer.
1868
1869 =back
1870
1871 C<$iteminformation> is a reference-to-hash, giving information about the
1872 returned item from the issues table.
1873
1874 C<$borrower> is a reference-to-hash, giving information about the

2659 the limit on the number of times that the loan can be renewed
2660 (as controlled by the item type) to be ignored. Overriding also allows
2661 to renew sooner than "No renewal before" and to manually renew loans
2662 that are automatically renewed.

2665 item must currently be on loan to the specified borrower; renewals
2666 must be allowed for the item's type; and the borrower must not have
2667 already renewed the loan. $error will contain the reason the renewal can not proceed

2884 Renews a loan.
2885
2886 C<$borrowernumber> is the borrower number of the patron who currently
2887 has the item.
2888
2889 C<$itemnumber> is the number of the item to renew.
2890
2891 C<$branch> is the library where the renewal took place (if any).
2892            The library that controls the circ policies for the renewal is retrieved from the issues record.
2893
2894 C<$datedue> can be a DateTime object used to set the due date.
2895
2896 C<$lastreneweddate> is an optional ISO-formatted date used to set issues.lastreneweddate.  If
2897 this parameter is not supplied, lastreneweddate is set to the current date.
2898
2899 C<$skipfinecalc> is an optional boolean. There may be circumstances where, even if the
2900 CalculateFinesOnReturn syspref is enabled, we don't want to calculate fines upon renew,
2901 for example, when we're renewing as a result of a fine being paid (see RenewAccruingItemWhenPaid
2902 syspref)
2903
2904 If C<$datedue> is the empty string, C<&AddRenewal> will calculate the due date automatically
2905 from the book's item type.
