Alexandria is a project and a library. As a project Alexandria’s goal is to reduce duplication of effort and improve portability of Common Lisp code according to its own idiosyncratic and rather conservative aesthetic. As a library Alexandria is one of the means by which the project strives for its goals.

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.

result-list---a list. 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." (I noticed because it complicated the definition of "mappend" in an earlier post.) Common Lisp APPEND takes 0 or more (&rest). Emacs Lisp append takes 0 or more (&rest). To demonstrate the higher-order-function style of programming, we will define a new function called mappend. It takes two arguments, a function and a list.

It takes two arguments, a function and a list. mappend maps the function over each element of the list and appends together all the results. Function: pipe-mappend-filtering FN PIPE &optional FILTER-PRED. Map fn over pipe, delaying all but the first fn call, appending results while filtering.

The code for this chapter is located in the file simple.lisp, but note that the file does not include the mappend function from section 1.7. The mappend!

result---an object.This will be a list unless the last list was not a list and all preceding lists were null.

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.

The primitive function ``cons'' allows you to add a member to the front of a list. Here are two examples: 5.4 Building Cons Cells and Lists. Many functions build lists, as lists reside at the very heart of Lisp.
