wrap

Description

Wraps text so that each line has a specified maximum number of characters.

History

ColdFusion MX 6.1: Added this function.

Syntax

Wrap(string, limit[, strip])

Attributes

Attribute	Description	Required	Default
limit	Positive integer maximum number of characters to allow on a line.
string	String or variable that contains one. The text to wrap.
strip	Boolean value specifying whether to remove all existing newline and carriage return characters in the input string with spaces before wrapping the text. The default value is False.

Returns

String containing the wrapped text.

Usage

Inserts line break at the location of the first white space character (such as a space, tab, or new line) before the specified limit on a line. If a line has no whitespace characters before the limit, inserts a line break at the limit. Uses the operating-system specific line break: newline for UNIX, carriage return and newline on Windows.
If you specify the strip parameter, all existing line breaks are removed, so any paragraph formatting is lost.
Use this function to limit the length of text lines, such as text to be included in a mail message. The cfmail and cfmailpart tag wraptext attributes use this function

Example

<h3>Wrap Example</h3> 
<cfset inputText="This is an example of a text message that we want to wrap. It is rather long and needs to be broken into shorter lines."> 
<cfoutput>#Wrap(inputText, 59)#</cfoutput>
