Replace " with \" in a string

[svucic]

Hi everyone,

as the title says i'm trying to replace the quotes in a path with \".

Example:

"C:\\Users\\Something\\Desktop\\Something"

to

\"C:\\Users\\Something\\Desktop\\Something\"

What is it? Content of an (M)TEXT entity?

Spoiler

; if so, then getting string of a content
(cdr (assoc 1 (entget (car (entsel)))))

receive
"\"C:\\\\Users\\\\Something\\\\Desktop\\\\Something\""

Or a value of a STRING variable?

It's a value of a STRING variable.

Try this...

(strcat "\"" "C:\\Users\\Something\\Desktop\\Something" "\"")

or if you have a variable called filepath, then

(strcat "\"" filepath "\"")

which gives you

"\"C:\\Users\\Something\\Desktop\\Something\""

Outer quotation marks are a part of a string definition, can't omit those.

Wel, I'm using (setq DirPath (acet-ui-pickdir)) to get the path to a folder which I'm passing to an external program. 

And the path that i'm passing to the program should be like this:

\"C:\\Users\\Srdjan\\Documents\\test.csv\"

Example of executing external program:

(dos_execute "program -input:\"C:\\Users\\Something\\Desktop\\Something\" -output:\"C:\\Users\\Something\\Desktop\\Something\" -definition:\"C:\\Users\\Something\\Desktop\\Something\"" 0)

Try something like this...

(setq filepath "C:\\Users\\Something\\Desktop\\Something")
(setq filepathquited (strcat "\"" filepath "\""))

(setq depars (strcat "program"
                     " -input:" filepathquited
                     " -output:" filepathquited
                     " -definition:" filepathquited))

(dos_execute depars 0)

Or, it may be more obvious without variables...

(dos_execute (strcat "program"
                     " -input:" "\"" filepath "\""
                     " -output:" "\"" filepath "\""
                     " -definition:" "\"" filepath "\"")
  0)

Works. Thank you BeeKeeCZ 🙂
