#+TITLE: The =CL-GAP-BUFFER= Library #+AUTHOR: Robert Smith #+EMAIL: quad@symbo1ics.com * Summary A small library for efficient-local-insertion strings represented as gap buffers. It operates efficiently for cursor-based editing. * Usage The principle use follows. Mutable operations' output is elided. Create a gap buffer. : > (defparameter buf (make-gap-buffer)) Add some data to it. : > (gap-buffer-insert-string buf "hello") : > (gap-buffer-string buf) : "hello" : > (gap-buffer-insert-char buf #\a) : > (gap-buffer-string buf) : "helloa" Move about in the gap buffer. : > (gap-buffer-move-left buf) : > (gap-buffer-move-left buf) : > (gap-buffer-insert-char buf #\y) : > (gap-buffer-string buf) : "hellyoa" Remove characters. : > (gap-buffer-move-right buf) : > (gap-buffer-backspace buf) : > (gap-buffer-string buf) : "hellya" : > (gap-buffer-insert-char buf #\e) : > (gap-buffer-string buf) : "hellyea" : > (gap-buffer-delete buf) : > (gap-buffer-string buf) : "hellye" : > (gap-buffer-insert-char buf #\s) : > (gap-buffer-string buf) : "hellyes" * Dependencies None. * License See the file ~LICENSE~. ---------- ### End of file
