 134 =head1 NAME
 135
 136 C4::Circulation - Koha circulation module
 137
 138 =head1 SYNOPSIS
 139
 140 use C4::Circulation;
 141
 142 =head1 DESCRIPTION
 143
 144 The functions in this module deal with circulation, issues, and
 145 returns, as well as general information about the library.
 146 Also deals with inventory.
 147
 148 =head1 FUNCTIONS
 149
 150 =head2 barcodedecode
 151
 152   $str = &barcodedecode($barcode, [$filter]);
 153
 154 Generic filter function for barcode string.
 155 Called on every circ if the System Pref itemBarcodeInputFilter is set.
 156 Will do some manipulation of the barcode for systems that deliver a barcode
 157 to circulation.pl that differs from the barcode stored for the item.
 158 For proper functioning of this filter, calling the function on the
 159 correct barcode string (items.barcode) should return an unaltered barcode.
 160
 161 The optional $filter argument is to allow for testing or explicit
 162 behavior that ignores the System Pref.  Valid values are the same as the
 163 System Pref options.

 254
 255 Transfers an item to a new branch. If the item is currently on loan, it is automatically returned before the actual transfer.
 256
 257 C<$newbranch> is the code for the branch to which the item should be transferred.
 258
 259 C<$barcode> is the barcode of the item to be transferred.
 260
 261 If C<$ignore_reserves> is true, C<&transferbook> ignores reserves.
 262 Otherwise, if an item is reserved, the transfer fails.
 263
 264 Returns three values:
 265
 266 =over
 267
 268 =item $dotransfer
 269
 270 is true if the transfer was successful.
 271
 272 =item $messages
 273
 274 is a reference-to-hash which may have any of the following keys:
 275
 276 =over
 277
 278 =item C<BadBarcode>
 279
 280 There is no item in the catalog with the given barcode. The value is C<$barcode>.
 281
 282 =item C<DestinationEqualsHolding>
 283
 284 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.
 285
 286 =item C<WasReturned>
 287
 288 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.
 289
 290 =item C<ResFound>
 291
 292 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>.
 293
 294 =item C<WasTransferred>
 295
 296 The item was eligible to be transferred. Barring problems communicating with the database, the transfer should indeed have succeeded. The value should be ignored.

1226
1227 Issue a book. Does no check, they are done in CanBookBeIssued. If we reach this sub, it means the user confirmed if needed.
1228
1229 =over 4
1230
1231 =item C<$borrower> is a hash with borrower informations (from Koha::Patron->unblessed).
1232
1233 =item C<$barcode> is the barcode of the item being issued.
1234
1235 =item C<$datedue> is a DateTime object for the max date of return, i.e. the date due (optional).
1236 Calculated if empty.
1237
1238 =item C<$cancelreserve> is 1 to override and cancel any pending reserves for the item (optional).
1239
1240 =item C<$issuedate> is the date to issue the item in iso (YYYY-MM-DD) format (optional).
1241 Defaults to today.  Unlike C<$datedue>, NOT a DateTime object, unfortunately.
1242
1243 AddIssue does the following things :
1244
1245   - step 01: check that there is a borrowernumber & a barcode provided
1246   - check for RENEWAL (book issued & being issued to the same patron)
1247       - renewal YES = Calculate Charge & renew
1248       - renewal NO  =
1249           * BOOK ACTUALLY ISSUED ? do a return if book is actually issued (but to someone else)
1250           * RESERVE PLACED ?
1251               - fill reserve if reserve to this patron
1252               - cancel reserve or not, otherwise
1253           * TRANSFERT PENDING ?
1254               - complete the transfert
1255           * ISSUE THE BOOK
