I'm just starting to play around with emacs lisp. A quick question. How
can I manipulate variables in elisp? For instance, I want to take a
string and add a backslash(escape) to all whitespace. Like in a path like
"c:/Documents and settings/" I want to change it to
"c:/Documents\ and\ Settings/".
Something similar to this in perl: $var =~ s/( )/\\$1/g;
Thanks,
Matt

\ are unfine in Emacs lisp but here we go
(defvar *str* "c:\\Dokumente und Einstellungen\\")
(replace-in-string *str* (regexp-quote "\\") "/" )
"c:/Dokumente und Einstellungen/"
If I would not use regexp-quote I would have to write
"\\\\" the so calles scatterd tootpick syndrome ;-)
If you would just have nearly everything else it would be easier

Friedrich

'replace-in-string' doesn't seem to be defined 21.2.1...
However, 'dired-replace-in-string' is if you (require 'dired)
