Trim bytes from left or right of string (String class)
[Introduced in Sirius Mods 7.9]
These methods remove a specified number of bytes from the left or right end of a string.
Syntax
%outString = string:TrimLeft( amount)
%outString = string:TrimRight( amount)
Syntax terms
| %outString | Is the string that results from removing amount bytes from the left or right of string. |
|---|---|
| string | The method string object from which bytes are removed. |
| amount | The number of bytes to remove from the left or right of string. |
Usage notes
- An amount of 0 results in the output string being set equal to the value of string.
- A negative amount or an amount greater than 231 results in request cancellation.
- An amount greater than or equal to the length of string results in the output string being set to a null string.
- TrimLeft accomplishes the same thing as SubString when used with just the starting position and without a length. While it might be a little bit more efficient than SubString, it's mainly available for completeness.
- TrimRight functionality can be achieved by using the Left and Length functions but it is considerably more efficient and convenient than doing so.
Examples
The following code:
begin %ls is longstring %ls = 'Life is good':trimRight(1) printText {~} = '{%ls}' %ls = 'Life is good':trimLeft(3) printtext {~} = '{%ls}' end
outputs:
%ls = 'Life is goo' %ls = 'e is good'
