One use +;; is to build a radix tree of list of string, e.g. from a filesystem +;; hierarchy. + +;; There are many different options for how to represent radix trees +;; in Elisp. Here I chose a very simple one. A radix-tree can be either: +;; - a node, of the form ((PREFIX . PTREE) . RTREE) where PREFIX is a string +;; meaning that everything that starts with PREFIX is in PTREE, +;; and everything else in RTREE. It also has the property that +;; everything that starts with the first letter of PREFIX but not with +;; that whole PREFIX is not in RTREE (i.e. is not in the tree at all). +;; - anything else is taken as the value to associate with the empty string. +;; So every node is basically an (improper) alist where each mapping applies +;; to a different leading letter. +;; +;; The main downside of this representation is that the lookup operation +;; is slower because each level of the tree is an alist rather than some kind +;; of array, so every level's lookup is O(N) rather than O(1). We could easily +;; solve this by using char-tables instead of alists, but that would make every +;; level take up a lot more memory, and it would make the resulting +;; data structure harder to read (by a human) when printed out. + +;;; Code: +(defvar radix-tree-compare-function 'compare-strings) +(defvar radix-tree-type 'string) + +(defun radix-tree--insert (tree key val i) + (pcase tree + (`((,prefix . ,ptree) . ,rtree) + (let* ((ni (+ i (length prefix))) + (cmp (funcall radix-tree-compare-function prefix nil nil key i ni))) + (if (eq t cmp) + (let ((nptree (radix-tree--insert ptree key val ni))) + `((,prefix . ,nptree) . ,rtree)) + (let ((n (if (< cmp 0) (- -1 cmp) (- cmp 1)))) + (if (zerop n) + (let ((nrtree (radix-tree--insert rtree key val i))) + `((,prefix . ,ptree) . ,nrtree)) + (let* ((nprefix (substring prefix 0 n)) + (kprefix (substring key (+ i n))) + (pprefix (substring prefix n)) + (ktree (if (equal kprefix "") val + `((,kprefix . ,val))))) + `((,nprefix + .
