string_array_subset

Synopsis

Provides prim[start:end] functionality for string arrays.

Inputs

Name Type Description
in string [] array of strings
start int start of string range
end int end of string range

Output Ports

Name Type Description
out string [] subset of array in

Description

The useful subset syntax [start:end] is only implimented for prims, in fact Express tells you that it's "not currently" implimented for strings. This module does exactly that.

Parameters

Inputs

in

An array of strings.

start

Using 0 indexing the start of the subset you want to extract.

end

Using 0 indexing the end of the subset you want to extract.

Outputs

out

The string array equivalent to in[start:end].

Example

The Macro returns a subset of the input array of strings:

Input: 

	in[6] = {"text0","text1","text2","text3","text4","text5"}
	start = 2
	end = 4

Output: 

	out[3] = {"text2","text3","text4"}
