191 SL::MoreCommon.pm - helper functions
195 this is a collection of helper functions used in kivitendo.
196 Most of them are either obvious or too obscure to care about unless you really have to.
197 The exceptions are documented here.
207 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.
209 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.
211 =item cross BLOCK ARRAY ARRAY
213 Evaluates BLOCK for each combination of elements in ARRAY1 and ARRAY2
214 and returns a new list consisting of BLOCK's return values.
215 The two elements are set to $a and $b.
216 Note that those two are aliases to the original value so changing them
217 will modify the input arrays.
219 # append each to each
222 @x = cross { "$a$b" } @a, @b;
223 # returns a1, a2, a3, b1, b2, b3, c1, c2, c3
225 As cross expects an array but returns a list it is not directly chainable
226 at the moment. This will be corrected in the future.
228 =item ary_to_hash INDEX_KEY, VALUE_KEY, ARRAY
230 Returns a hash with the content of ARRAY based on the values of
231 INDEX_KEY and VALUE_KEY.
233 If INDEX_KEY is undefined then the elements of ARRAY are the keys and
234 '1' is the value for each of them.
236 If INDEX_KEY is defined then each element of ARRAY is checked whether
237 or not it is a hash. If it is then its element at the position
238 INDEX_KEY will be the resulting hash element's key. Otherwise the
239 element is assumed to be a blessed reference, and its INDEX_KEY
240 function will be called.
242 The values of the resulting hash follow a similar pattern. If
243 VALUE_KEY is undefined then the current element itself is the new hash
244 element's value. If the current element is a hash then its element at
245 the position VALUE_KEY will be the resulting hash element's
246 key. Otherwise the element is assumed to be a blessed reference, and
247 its VALUE_KEY function will be called.
