idomatic batch processing of text in emacs?
- by Stephen
In python, you might do something like
fout = open('out','w')
fin = open('in')
for line in fin:
fout.write(process(line)+"\n")
fin.close()
fout.close()
(I think it would be similar in many other languages as well).
In emacs lisp, would you do something like
(find-file 'out')
(setq fout (current-buffer)
(find-file 'in')
(setq fin (current-buffer)
(while moreLines
(setq begin (point))
(move-end-of-line 1)
(setq line (buffer-substring-no-properties begin (point))
;; maybe
(print (process line) fout)
;; or
(save-excursion
(set-buffer fout)
(insert (process line)))
(setq moreLines (= 0 (forward-line 1))))
(kill-buffer fin)
(kill-buffer fout)
which I got inspiration (and code) from here. Or should I try something entirely different? And how to remove the "" from the print statement? Thanks!
