From acc561366f3fe6ec0377103f52ef0f7e923711c9 Mon Sep 17 00:00:00 2001 From: Rose Hogenson Date: Mon, 1 Aug 2022 19:35:19 -0700 Subject: Modify the project structure. Now the lib directory contains what will eventually end up on the user's /usr/lib/csc. When I write make install, it will copy all of the .csc files from lib into the destination lib directory. This means I can start working on the standard library in lib/scheme. --- csc/sort.csc | 28 ---------------------------- 1 file changed, 28 deletions(-) delete mode 100644 csc/sort.csc (limited to 'csc/sort.csc') diff --git a/csc/sort.csc b/csc/sort.csc deleted file mode 100644 index 6be1e16..0000000 --- a/csc/sort.csc +++ /dev/null @@ -1,28 +0,0 @@ -(define-library (csc sort) - (export sort) - (import (scheme base) - (only (csc list) - revappend - split-at)) - (begin - - - (define (sort-len cmp xs len) - (if (<= len 1) - xs - (let ((n/2 (truncate-quotient len 2))) - (let-values (((half-a half-b) (split-at n/2 xs))) - (let ((sorted-half-a (sort-len cmp half-a n/2)) - (sorted-half-b (sort-len cmp half-b (- len n/2)))) - (let loop ((a sorted-half-a) - (b sorted-half-b) - (acc '())) - (cond ((null? a) (revappend acc b)) - ((null? b) (revappend acc a)) - ((cmp (car b) (car a)) - (loop a (cdr b) (cons (car b) acc))) - (else (loop (cdr a) b (cons (car a) acc)))))))))) - - - (define (sort cmp xs) - (sort-len cmp xs (length xs))))) -- cgit v1.3.1
