$truncate

Usage: $truncate(text,length)

Category: text

Implemented: Picard 0.12

Description:

Truncate text to length. If length is less than 0, then the value used is the number of characters in text plus length (e.g.: $truncate(abcd,-1) is the same as $truncate(abcd,3)). If length is missing or a negative number greater than the number of characters in text, the function will return an empty string.

Example:

The following statements will return the values indicated:

$truncate(Once upon a time,)     ==>  ""
$truncate(Once upon a time,0)    ==>  ""
$truncate(Once upon a time,3)    ==>  "Onc"
$truncate(Once upon a time,-3)   ==>  "Once upon a t"
$truncate(Once upon a time,-30)  ==>  ""
