Category:LSL String

A string is text data. The length of a string is only limited by available script memory. String values are enclosed in double quotes when defined in LSL text. Any character may be used in a string though some will need to be escaped.

Strings can be concatenated using the + operator.

**Escape codes**
Substring	Replaced with
\t	four spaces
\n	new line
\"	double quote
\\	backslash

String examples:

"Hello Avatar!"
"Yes"
"No"
"It's 10 o'clock."
"I am 21 years old!"
"Help " + "me"
EOF
//The following two strings have the same value.
"I scream,\nyou scream,\nwe all scream,\nfor ice-cream!"
"I scream,
you scream,
we all scream,
for ice-cream!"

Note: escape codes (listed above) are translated when the script is compiled, and not while it's running. The result: only strings that are inside your script when it is compiled will get, say, \n turned into a "new line" character. Text you read in from a notecard, chat, http, etc, will not be checked for escape codes -- that same \n typed in a notecard doesn't automatically turn into a "new line" character in any case. You'll have to do that yourself, if you really really need it for some reason.

Variable: string name;

string name;

Declares a variable of type string named name, with the value ""

• variable

name

–

variable name

Variable: string name = value;

string name = value;

Declares a variable of type string named name, with the value value.

• variable	name	–	variable name
• expression	value	–	string expression or constant

Typecast: (string)value

(string)value

Converts value to a value of type string.

• expression

value

–

expression or constant

Operators

See Operators for more information.

Combine: value1 + value2

(value1 == value2)

Combines two strings into a single string without modifying the inputs. Appends value2 to value1 and returns the resulting string.

• expression	value1	–	string expression or constant
• expression	value2	–	string expression or constant

Comparison: value1 == value2

(value1 == value2)

Compares two strings, returns one if same length and same characters, else returns zero. This operator works exactly like !strcmp(value1, value2) in C, thus technically differs from the counterintuitive behavior of the == operator in C and in Java.

• expression	value1	–	string expression or constant
• expression	value2	–	string expression or constant

Comparison: value1 != value2

(value1 == value2)

Compares two strings, returns zero if same length and same characters, otherwise non-zero. This operator works exactly like strcmp(value1, value2) in C, thus technically differs from the counterintuitive behavior of the != operator in C and in Java.

• expression	value1	–	string expression or constant
• expression	value2	–	string expression or constant

Examples

integer int = 48934;
string str = (string)int;
string str_2;
str_2 = str;
