In Groovy 1.7.3 the
tr() method is added to the
String class. With this method we can do translations in String values. We define a source set of characters that need to be replaced by a replacement set of characters. We can also use a regular expression style (remember it is not a real regular expression) to define a range of characters.
If the replacement set is smaller than the source set, than the last character of the replacement set is used for the remaining source set characters.
// Source set and replacement set are equal size. assert 'I 10v3 9r00vy' == 'I love Groovy'.tr('loeG', '1039') // Regular expression style range assert 'mrHAKI' == 'mrhaki'.tr('a-k', 'A-K') // Replacement set is smaller than source set. assert 'Gr8888' == 'Groovy'.tr('ovy', '8')
