Here’s some PeopleCode I wrote that will add a carriage return and line feed to the end of a String if it is not empty:
|
1 2 3 4 5 6 7 8 9 |
Function addEnter(&str As string) Returns string /* Adds a carriage return and line feed to the String if it is not empty */ If None(&str) Then Return &str; Else Return &str | Char(13) | Char(10)); End-If; End-Function; |
or as a method:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 |
method addEnter(&str As string) Returns string; method addEnter /+ &str as String +/ /+ Returns String +/ /* Adds a carriage return and line feed to the String if it is not empty */ If None(&str) Then Return &str; Else Return (&str | Char(13) | Char(10)); End-If; end-method; |
Note: This assumes that you want Windows line endings. Typically unix line endings just have a single line feed (Char(10) with no carriage return.
