A function can be created to get a file string:
(defun get-file-string (fileName)
(let ( fileString )
(setq fileString
(with-temp-buffer
(insert-file-contents fileName)
(buffer-string)))))
allowing:
(setq findreplace_01_A
(get-file-string "findreplace_01_A.txt"))
and a loop can be used with the function:
(progn
(defvar findReplacePairsList nil
"A list of replacement pairs. Each element is a vector of 2 elements.
Each element is a string, from a file content.")
(let (
( fileNames (vector "findreplace_01_A.txt"
"findreplace_01_B.txt"
"findreplace_02_A.txt"
"findreplace_02_B.txt"
"findreplace_03_A.txt"
"findreplace_03_B.txt"))
(fileStrings (make-vector 6
""))
(i 0 ) )
(while (< i 6)
(aset fileStrings i
(get-file-string (elt fileNames i)))
(setq i (1+ i) ) )
(setq findReplacePairsList (list
(vector (elt fileStrings 0)
(elt fileStrings 1))
(vector (elt fileStrings 2)
(elt fileStrings 3))
(vector (elt fileStrings 4)
(elt fileStrings 5))
))))
