180 SL::MoreCommon.pm - helper functions
184 this is a collection of helper functions used in kivitendo.
185 Most of them are either obvious or too obscure to care about unless you really have to.
186 The exceptions are documented here.
196 A lot of the old sql-ledger routines are strictly procedural. They search for params in the $form object, do stuff with it, and return a status code.
198 Once in a while you'll want something from such a function without altering $form. Yeah, you could rewrite the routine from scratch... not. Just save you form, execute the routine, grab your results, and restore the previous form while you curse at the original design.
200 =item cross BLOCK ARRAY ARRAY
202 Evaluates BLOCK for each combination of elements in ARRAY1 and ARRAY2
203 and returns a new list consisting of BLOCK's return values.
204 The two elements are set to $a and $b.
205 Note that those two are aliases to the original value so changing them
206 will modify the input arrays.
208 # append each to each
211 @x = cross { "$a$b" } @a, @b;
212 # returns a1, a2, a3, b1, b2, b3, c1, c2, c3
214 As cross expects an array but returns a list it is not directly chainable
215 at the moment. This will be corrected in the future.
217 =item ary_to_hash INDEX_KEY, VALUE_KEY, ARRAY
219 Returns a hash with the content of ARRAY based on the values of
220 INDEX_KEY and VALUE_KEY.
222 If INDEX_KEY is undefined then the elements of ARRAY are the keys and
223 '1' is the value for each of them.
225 If INDEX_KEY is defined then each element of ARRAY is checked whether
226 or not it is a hash. If it is then its element at the position
227 INDEX_KEY will be the resulting hash element's key. Otherwise the
228 element is assumed to be a blessed reference, and its INDEX_KEY
229 function will be called.
231 The values of the resulting hash follow a similar pattern. If
232 VALUE_KEY is undefined then the current element itself is the new hash
233 element's value. If the current element is a hash then its element at
234 the position VALUE_KEY will be the resulting hash element's
235 key. Otherwise the element is assumed to be a blessed reference, and
236 its VALUE_KEY function will be called.
