New page

<pre>
Match( <string>, <pattern>, <offset> )
</pre>

=== Description ===

Search for the first match of pattern in a string if found return the captures from the pattern.

=== Parameters ===

==== string ====

The string to evaluate.

==== pattern ====

Go read the Patterns section on the [[Core Function Find|Find( )]] function to learn how to create and use patterns then come back here to put it to use on this function.

==== offset ====

Optional; Specifies where to start the search; its default value is 0 and can be negative.

=== Return Value ===

=== Remarks ===

This function is pretty much the same a the LUA String.Match() however this one returns start position starting at 0 (LUA's starts at 1) and lowers the end position by 1, Also the Offset begins at 0 here where as in LUA it begins at 1.

This is because in Sputnik chars in a string start at 0 not 1.

=== Example ===
