Re: Transposing Regular Expression

[LanX]

Hi

I'm a newbie in elisp, but this works for me:

--------- tested in M-x ielm
ELISP> (defun pl-tr (STRING FROM TO)
         "perlish transpose"
         (replace-regexp-in-string
          (concat "\[" FROM "\]")
          (lambda (s)
            (string (elt TO (search s FROM))))
          STRING)
         )
pl-tr
ELISP> (pl-tr "fedcba" "bcd" "BCD")
"feDCBa"

HTH
