 103
 104 C4::Circulation - Koha circulation module
 105
 106 =head1 SYNOPSIS
 107
 108 use C4::Circulation;
 109
 110 =head1 DESCRIPTION
 111
 112 The functions in this module deal with circulation, issues, and
 113 returns, as well as general information about the library.
 114 Also deals with stocktaking.
 115
 116 =head1 FUNCTIONS
 117
 118 =head2 barcodedecode
 119
 120   $str = &barcodedecode($barcode, [$filter]);
 121
 122 Generic filter function for barcode string.
 123 Called on every circ if the System Pref itemBarcodeInputFilter is set.
 124 Will do some manipulation of the barcode for systems that deliver a barcode
 125 to circulation.pl that differs from the barcode stored for the item.
 126 For proper functioning of this filter, calling the function on the
 127 correct barcode string (items.barcode) should return an unaltered barcode.
 128
 129 The optional $filter argument is to allow for testing or explicit
 130 behavior that ignores the System Pref.  Valid values are the same as the
 131 System Pref options.

 156         # Why drop the nonzero digit after the T?
 157         # Why pass non-digits (or empty string) to "T%07d"?

 160 }
 161
 162 =head2 decode
 163
 164   $str = &decode($chunk);
 165
 166 Decodes a segment of a string emitted by a CueCat barcode scanner and
 167 returns it.
 168
 169 FIXME: Should be replaced with Barcode::Cuecat from CPAN
 170 or Javascript based decoding on the client side.

 204                                             $barcode, $ignore_reserves);
 205
 206 Transfers an item to a new branch. If the item is currently on loan, it is automatically returned before the actual transfer.
 207
 208 C<$newbranch> is the code for the branch to which the item should be transferred.
 209
 210 C<$barcode> is the barcode of the item to be transferred.
 211
 212 If C<$ignore_reserves> is true, C<&transferbook> ignores reserves.
 213 Otherwise, if an item is reserved, the transfer fails.
 214
 215 Returns three values:
 216
 217 =over
 218
 219 =item $dotransfer
 220
 221 is true if the transfer was successful.
 222
 223 =item $messages
 224
 225 is a reference-to-hash which may have any of the following keys:
 226
 227 =over
 228
 229 =item C<BadBarcode>
 230
 231 There is no item in the catalog with the given barcode. The value is C<$barcode>.
 232
 233 =item C<IsPermanent>
 234
 235 The item's home branch is permanent. This doesn't prevent the item from being transferred, though. The value is the code of the item's home branch.
 236
 237 =item C<DestinationEqualsHolding>
 238
 239 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.
 240
 241 =item C<WasReturned>
 242
 243 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.
 244
 245 =item C<ResFound>
 246
 247 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>.
 248
 249 =item C<WasTransferred>
 250
 251 The item was eligible to be transferred. Barring problems communicating with the database, the transfer should indeed have succeeded. The value should be ignored.

 870
 871 =over 4
 872
 873 =item C<$borrower> is a hash with borrower informations (from GetMemberDetails).
 874
 875 =item C<$barcode> is the barcode of the item being issued.
 876
 877 =item C<$datedue> is a C4::Dates object for the max date of return, i.e. the date due (optional).
 878 Calculated if empty.
 879
 880 =item C<$cancelreserve> is 1 to override and cancel any pending reserves for the item (optional).
 881
 882 =item C<$issuedate> is the date to issue the item in iso (YYYY-MM-DD) format (optional).
 883 Defaults to today.  Unlike C<$datedue>, NOT a C4::Dates object, unfortunately.
 884
 885 AddIssue does the following things :
 886
 887   - step 01: check that there is a borrowernumber & a barcode provided
 888   - check for RENEWAL (book issued & being issued to the same patron)
 889       - renewal YES = Calculate Charge & renew
 890       - renewal NO  =
 891           * BOOK ACTUALLY ISSUED ? do a return if book is actually issued (but to someone else)
 892           * RESERVE PLACED ?
 893               - fill reserve if reserve to this patron
 894               - cancel reserve or not, otherwise
 895           * TRANSFERT PENDING ?
 896               - complete the transfert
 897           * ISSUE THE BOOK

1209 branch, same category), then failing that, default_circ_rules
1210 (default branch, default category).
