Word-o-mat is an extension for RoboFont that generates words for use in type sketching, spacing, testing, specimen-building etc.: Looking for words that contain ‘q’ but not ‘u’? Or French words that use an ‘a’, a ‘g’, at least one ascender, and one diagonal, but only glyphs you’ve marked green? Or words in which to see a specific letter combination, like ‘fk’ or ‘Yc’? This is the sort of thing that word-o-mat can help you with. Its controls allow you to specify required letters or groups of letters that the words should contain; or for more fine-grained control, pattern-matching with regular expressions. The current version comes with built-in word lists for 17 languages plus the ability to use custom word lists.
