This last part is so that all functions in the grammar will return a list of words. That way, we can freely apply append to any category. ( defun one-of (set) "Pick one element of set, and make a list of it." ( list (random-elt set))) ( defun random-elt (choices) "Choose an element from a list at random."

Chapter 2 introduces Common Lisp through the creation of a series of ways of doing generation of language sentences in English, based on simple grammars. It’s an interesting chapter to start with since the code is simple and makes it easy to compare the Ruby and Common Lisp versions. 2010-03-26 · LISP has been accepted as a working group of the IETF where Dino participates intimately authoring 7 Internet Drafts.

The mappend! procedure appends the given mutable lists by mutating the tail of each to refer to the next, using set-mcdr!.Empty lists are dropped; in particular, the result of calling mappend! with one or more empty lists is the same as the result of the call with the empty lists removed from the set of arguments. Note that this version of mappend doesn’t work exactly the same as Common Lisp mappend, since it doesn’t allow a lambda. Getting back to the generate method.
