How would you replace "/" with "\"?

Hi,

How would you replace "/" with "\"? using vl-string-translate.

(vl-string-translate "/" "\" "/zzz")
to return "\zzz"?

Hi,

In LISP, backslalsh is the escape character so you have to double it (have a look at this topic).

(vl-string-translate "/" "\\" "/zzz")

Eventually, I`d like to reach the tab syntax "\t" and run it through lisp. SO I will need the backslash to be one character.

You cannot use a single backslash, it have to associated with another character as control character ("\n", "\t") or as escape character ("\\", "\"").

It woulb be easier to help you if you provided a relevant example of what you want to achieve.

I`d like to create a piece of Mtext which includes a tab. 

(setq str (vl-string-translate "/" "\" "1./tzzz"))

(setpropertyvalue (entlast) "Contents" str "")

Should result: 1. tab zzz

You can use:

(setq str (vl-string-subst "/t" "\t" "1./tzzz"))

But you should simply do:

(setq str "1.\tzzz")

Thank you Gilles!

I did a minor revision. (setq str (vl-string-translate "/" "\t" str)). It had an extra t there. Now it`s working like a charm! 🙂

Keep in mind you have to consider "\n", "\t", "\\", "\"" as single characters.
