This one gets me every now and then. Something I am not seeing but for the life of me...
Yes, match() works.
Any thoughts would be appreciated.
include std/console.e sequence haystack = "just in time" object needle = "in" printf (1,"location = %d\n",eu:find(needle,haystack)) any_key("<cr>")
Returns a zero, meaning not found.
From the documentation:
8.15.2.1 find
<built-in> function find(object needle, sequence haystack, integer start)
Find the first occurrence of a "needle" as an element of a "haystack", starting from position "start"..
Parameters:
needle : an object whose presence is being queried
haystack : a sequence, which is being looked up for needle
start : an integer, the position at which to start searching. Defaults to 1.
Returns:
An integer, 0 if needle is not on haystack, else the smallest index of an element of haystack that equals needle.
