A string is a variable type that contains text. Possible length and characters depend on the game and its version.

ⓘ
The encoding should be mostly transparent. The input files can be encoded both in UTF-16 or UTF-8, the toString and toArray functions always convert from/to UTF-16 representation.


Properties

OFP ArmA Arma 2 Arma 2:OA TKOH Arma 3 (before v1.56) Arma 3 (since v1.56)
Max length 2056 No set limit 9,999,999 to 10,000,000
(same as Array length)
Encoding ASCII Unicode

{text} Checked Unchecked


Commands and Functions


Single quote limitation

Other than double quotes ("text"), single quotes ('text') do not seem to support tabs:

_string = " "; copyToClipboard _string; diag_log format ["%1 %2 %3 x%4x", toArray _string, toArray copyFromClipboard, toArray (_string select [0]), _string]; /* return is good: "[9,10,9] [9,10,9] [9,10,9] x x" */

_string = ' '; copyToClipboard _string; diag_log format ["%1 %2 %3 x%4x", toArray _string, toArray copyFromClipboard, toArray (_string select [0]), _string]; /* return: "[9,10] [9,10] [9,10] x x" - second tab vanished */

Examples

Quotes in Quotes

private _string = "my string ""with"" quotes"; private _string = 'my string "with" quotes'; private _string = 'my string with quotes';

String Formats

// Operation Flashpoint _string = "Hello there" // works _string = 'Hello there' // does NOT work _string = {Hello there} // works

// since Armed Assault _string = "Hello there" // works _string = 'Hello there' // works _string = {Hello there} // does NOT work

Operators

private _finalString = "Hello" + " " + "there"; // outputs "Hello there" - the + sign concatenates strings

The only basic operator to be used on strings is "plus". You can use "plus" to concatenate two strings.

Conversion

private _value = 42; // this is a Number hint _value; // error - hint takes a String, not a Number hint format ["%1", _value]; // ok hint str _value; // ok - since Armed Assault
