Subject: insert-string-centered / column before $ appears?
Date: Wed, 04 Mar 2020 00:21:16 +0100 [thread overview]
Message-ID: <87eeu96n4j.fsf@ebih.ebihd> (raw)
(defun insert-string-centered (string &optional far-right)
(interactive
`(,(read-from-minibuffer "string: ")
,(string-to-number
(read-from-minibuffer "far-right column [default 69]: ") )))
(let*((max (if (< 0 far-right) far-right 69))
(str-len (length string))
(padding (+ (/ (- max str-len) 2)
(if (= 0 (mod str-len 2)) 1 0)))
(padding-str (make-string padding ?\ )))
(insert padding-str string) ))
One (?) issue: 69 which is hardcoded above is the column that
appears right before the $ char appears in Emacs.
I take it this is stored somewhere?
