[ string->getpropertyvalue ]

Method

This method returns the Unicode property value for the indicated character. Unicode properties are defined in the Unicode Character Database (UCD) and Unicode Technical Reports (UTR). For details about the properties see http://www.unicode.org/.

Lasso defines many values for these Unicode property names. All of these values have the UCHAR_ prefix.

Syntax

THE_STRING->getPropertyValue(CHAR_POSITION, PROPERTY_NAME)

Examples

Beginner

This example uses [string->getPropertyValue] for each character of the sample string to determine the character category ID.

Code

local(str = 'As someone once said, "星星之火可以燎原"')

with i in 1 to #str->size
select #str->getPropertyValue(#i, UCHAR_GENERAL_CATEGORY)

Result

1, 2, 12, 2, 2, 2, 2, 2, 2, 2, 12, 2, 2, 2, 2, 12, 2, 2, 2, 2, 23, 12, 23, 5, 5, 5, 5, 5, 5, 5, 5, 23
