Parsing $INSTDIR

Hi,
I'm a newbie, and I started to use NSIS just few days ago.
I read some of these posts of the forum and some of the tutorial on the nsis website, but I didn't find the answer to my question.
I would like to add to my nsi a code to set a variable the parsed value of an existing variable.
For example: I need to parse $INSTDIR value. If e.g. $INSTDIR="C:\Program Files\MyApplication", I would like to create my new variable set to "C:/Program Files/MyApplication", changing backslashes ("\") with normal slashes ("/").
I would like to know what functions do this (with the syntax), or see examples given.
Any help is strongly appreciated.
Thank you very much.

Use the "StrFunc" header file. It provides many string manipulation macros!

!include "StrFunc.nsh"

${StrRep}



Section

  ${StrRep} $0 "$INSTDIR" "\" "/"

  MessageBox MB_OK 'Result: "$0"'

SectionEnd

See "Docs\StrFunc\StrFunc.txt" for more info 😉

Ops I forgot to update the post. I found WordReplace at /Docs/AppendixE.html#E.3 and seems to work fine.
Anyway tnx LoRd_MuldeR 🙂
