String

Atap Fiberglass & Tangki Fiberglass
A string is a sequence of characters limited in length only by available memory. Strings are enclosed in quotation marks ("). LSL uses UTF-8 for its encoding standard for strings.

Example:
Strings can be concatenated using the plus sign (+) operator.

The hack to increase max stored list size works for strings as well:


Example:
(In this example, the text "(string)PI_BY_TWO" converts the float constant PI_BY_TWO to a string. This process is called typecasting.)

Escape Characters

In LSL, strings can contain some backslash (\) escape characters:

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

These are just a subset of the backslash escape characters found in any other language. If a backslash is used in a string, and it is not paired up with one of the above characters and it will be treated as "\\". These escape characters only work in compiled scripts. In other words, a listener cannot be used to find the "new line" escape sequence and then treat it as the compiler would. However, a predefined string containing "\n" can be substituted for an input escape character sequence.

Functions
These functions are only a few of the many that use strings, but they're the ones that manipulate strings.

Function Name	Purpose
llDeleteSubString	Removes a slice of a string
llDumpList2String	Turns a list into a string
llParseString2List llParseStringKeepNulls	Turns a string into a list
llGetSubString	Extracts a part of a string
llInsertString	Inserts a string into a string
llToLower	Converts a string to lowercase
llToUpper	Converts a string to UPPERCASE
llStringLength	Gets the length of a string
llStringTrim	Trims leading and/or trailing spaces from a string
llSubStringIndex	Finds the position of a string in another string
llEscapeURL	Returns the string that is the URL-escaped version of url (replacing spaces with %20, etc)
llUnescapeURL	Returns the string that is the URL unescaped version of url, replacing "%20" with spaces, etc.

LSL doesn't appear to have any direct way to compare two strings for alphabetical order; here's a hack.
