Version: 2.0.

New page

== Description ==

'''Requires:''' [[LogicLib]].

'''Version:''' 2.0.

This function outputs the relative index position from the start or end of a string, where a substring is located.

== How To Use ==

=== Syntax ===

<highlight-nsis>
${StrLoc} "ResultVar" "String" "SubString" "StartPoint(>|<)"
</highlight-nsis>
or
<highlight-nsis>
Push "StartPoint(>|<)"
Push "SubString"
Push "String"
Call StrLoc
Pop "ResultVar"
</highlight-nsis>

=== Parameters ===

; ResultVar
: Buffer (variable) where the relative position index of "SubString" inside "String" is returned, according to "StartPoint". This value is always smaller or equal than "String" length. If "SubString" is not found, an empty value is returned.

; String
: String where to search for "SubString".

; SubString
: String to search in "String".

; StartPoint(>|<)
: Start position where the search begins and the counter starts. '''>''' = "String"'s start, '''<''' = "String"'s end. Default is '''>'''.

=== Example ===

<highlight-nsis>
${StrLoc} $0 "This is just an example" "just" "<"
;$0 = "11"
