strloc in reverse
the StrLoc macro in StrFunc can search backwards, but how can it find the last occurence?

I'm trying to find the last backslash on this path
c:\profiles\nikos

${StrLoc} $0 $PROFILE "\" "<"
$0 == 14!! (first backslash)

thanks

actually, StrLoc can't search backwards... the > vs < is just the direction counter. You'll want to use StrStrAdv or so...


${StrStrAdv} $0 $1 "\" "<" "<" 0 0 1
StrLen $0 $0

Or write your own function.. would be smaller :)
( might be something up in the wiki already anyway )

Or there's all types of word find functions includes as part of the WordFunc.nsh header.

See Appendix E of the NSIS help.
