Syntax:

string find substring

Parameters:

string: String - String to search in

substring: String - Substring to find

Syntax:

string find [substring, indexStart]

Parameters:

string: String - String to search in

substring: String - Substring to find

indexStart: Number - Zero based index which defines where find starts from

Return Value:

Number - Zero based position of the first sequence of characters that matches substring, -1 if not found

Examples

Example 1:

["Apples", "Oranges", "Pears"] find "Oranges"; // returns 1

Example 2:

[1, [2], [[3]]] find [[3]]; // returns 2 - does not work in OFP

Using nil on either side of find will make the whole statement return Nothing:

_array = [1,2,nil,4,5]; _result = _array find nil; hintSilent str (isNil "_result"); // true _result = nil find 1; hintSilent str (isNil "_result"); // true

find doesn't work with multidimensional arrays in OFP/CWA. It will always returns -1.

This command is unreliable/broken when it comes to some non-ASCII characters (as of Arma 3 1.58):

"abcßdef" find "c" // 2 "abcßdef" find "ß" // 3 "abcßdef" find "d" // 5

Not quite unreliable, just unexpected! Strings are tracked in terms of bytes rather than in actual character positions; all strings are stored in UTF-8 format. In other words, the eszett character is in Unicode, which takes up two bytes rather than one as it is within the 128-255 range of Unicode (similar results would be expected for the division symbol, the umlaut, accented e's, etc). Symbols that are particularly high in the Unicode range may take up three bytes, or even four for the truly exceptional characters, although Arma 3's default fonts are unlikely to render them. This definitely complicates any script which assumes any printable character is a single byte, however, and unfortunately I'm not skilled enough with internationalisation to recommend any robust fix.

If you want to return all occurences of a given string in a string use the following code. Thanks to sharp. for providing the code.

private _fnc_findStringsInString = { params ["_string", "_search"]; if (_string == "") exitWith {[]}; private _searchLength = count _search; private _return = []; private _i = 0; private _index = 0; while {_index = _string find _search; _index != -1} do { _string = _string select [_index + _searchLength]; _i = _i + _index + _searchLength; _return pushBack _i - _searchLength; }; _return }; ["Test,123,123,Test","Test"] call _fnc_findStringsInString; // returns [0,13]
