Much less, actually:
(let ((spaces '(0))
(line-count 1))
(with-current-buffer "org.el.gz"
(goto-char (point-min))
(while (not (looking-at "\\'"))
(push
(- (line-end-position)
(save-excursion (back-to-indentation) (point)))
spaces)
(cl-incf line-count)
;; beginning of next line
(goto-char (1+ (line-end-position)))))
(message "On average %f chars per line excluding indentation (%d lines)"
(/ (apply #'+ spaces) (float line-count))
line-count))
=> "On average 34.588839 chars per line excluding indentation (21235 lines)"
So around a comfy 35 chars of code per line. Also:
(let ((spaces '(0))
(line-count 1))
(with-current-buffer "org.el.gz"
(goto-char (point-min))
(while (not (looking-at "\\'"))
(push
(- (line-end-position)
(line-beginning-position))
spaces)
(cl-incf line-count)
;; beginning of next line
(goto-char (1+ (line-end-position)))))
(message "On average %f chars per line (%d lines)"
(/ (apply #'+ spaces) (float line-count))
line-count))
=> "On average 37.766847 chars per line (21235 lines)"
Your average line is 38 chars long, indentation included.
If anybody wants to replicate this, this is from a build of Emacs from
"931b9f5953013c1e8844d0c723411b87ccfedb1a".
