== Description ==
I also wrote a string replace function - this one can be optimized considerably if you know what you are replacing as I originally wrote it to replace /s with \s and vice versa - that version is at the end

== Usage ==
Syntax is the same as the other replace function:
<highlight-nsis>
Push "String to do replacement in (haystack)"
Push "String to replace (needle)"
Push "Replacement"
Call StrRep
Pop "$R0" ;result
</highlight-nsis>

== The Functions ==
=== StrRep ===
<highlight-nsis>
Function StrRep
Exch $R4 ; $R4 = Replacement String
Exch
Exch $R3 ; $R3 = String to replace (needle)
Exch 2
Exch $R1 ; $R1 = String to do replacement in (haystack)
Push $R2 ; Replaced haystack
Push $R5 ; Len (needle)
Push $R6 ; len (haystack)
Push $R7 ; Scratch reg
StrCpy $R2 ""
StrLen $R5 $R3
StrLen $R6 $R1
loop:
StrCpy $R7 $R1 $R5
StrCmp $R7 $R3 found
StrCpy $R7 $R1 1 ; - optimization can be removed if U know len needle=1
StrCpy $R2 "$R2$R7"
StrCpy $R1 $R1 $R6 1
StrCmp $R1 "" done loop
found:
StrCpy $R2 "$R2$R4"
StrCpy $R1 $R1 $R6 $R5
StrCmp $R1 "" done loop
done:
StrCpy $R3 $R2
Pop $R7
Pop $R6
Pop $R5
Pop $R2
Pop $R1
Pop $R4
Exch $R3
FunctionEnd
</highlight-nsis>

=== StrSlash ===
Here is my Slash to Backslash converter. The version shown uses similar registers to the StrRep function above, which is why it they are not contiguous or in a particularly logical order. Call it with the haystack and the direction on the stack as shown in the comment above it
<highlight-nsis>
; Push $filenamestring (e.g. 'c:\this\and\that\filename.htm')
; Push "\"
; Call StrSlash
; Pop $R0
; ;Now $R0 contains 'c:/this/and/that/filename.htm'
Function StrSlash
Exch $R3 ; $R3 = needle ("\" or "/")
Exch
Exch $R1 ; $R1 = String to replacement in (haystack)
Push $R2 ; Replaced haystack
Push $R4 ; $R4 = not $R3 ("/" or "\")
Push $R6
Push $R7 ; Scratch reg
StrCpy $R2 ""
StrLen $R6 $R1
StrCpy $R4 "\"
StrCmp $R3 "/" loop
StrCpy $R4 "/"
loop:
StrCpy $R7 $R1 1
StrCpy $R1 $R1 $R6 1
StrCmp $R7 $R3 found
StrCpy $R2 "$R2$R7"
StrCmp $R1 "" done loop
found:
StrCpy $R2 "$R2$R4"
StrCmp $R1 "" done loop
done:
StrCpy $R3 $R2
Pop $R7
Pop $R6
Pop $R4
Pop $R2
Pop $R1
Exch $R3
FunctionEnd
</highlight-nsis>
