How to find specific line number
Hi folks,

I couldn't find a function to search a text file with search string and return the matching line number(s) for further inline search/replace.
All current one's seems to need the line number as parameter.

Thanks in advance

OutFile "Output.exe"

!include "TextFunc.nsh"
!insertmacro LineFind
!insertmacro TrimNewLines

!include "WordFunc.nsh"
!insertmacro WordFind

Section
        StrCpy $R0 "SearchString"

        ${LineFind} "C:\input.txt" "C:\output.txt" "1:-1" "LineFindCallback"

        IfErrors 0 +2
        MessageBox MB_OK "Error"

        MessageBox MB_OKCANCEL '$$R9  "Line"=[$R9]$\n$$R8     "#" =[$R8]' IDOK +2
        StrCpy $0 StopLineFind

        end:

        Push $0
FunctionEnd
