StringUpTo (StringTokenizer function)
String from start to current position (StringTokenizer class)
[Introduced in Sirius Mods 7.8]
This method returns a substring of the tokenizing string, starting at the current position and ending just before the occurrence of its argument string. And it advances the tokenizer position past the next occurrence of its argument string.
Syntax
%string = stringTokenizer:StringUpTo( string)
Syntax terms
| %string | A string variable to contain the returned substring. |
|---|---|
| stringTokenizer | A StringTokenizer object expression. |
| string | The string within stringTokenizer up to which the tokenizer scans to determine the substring to return to %string.
If string is not found, StringUpTo returns the rest of the string being tokenized. |
Usage notes
- StringUpTo moves the tokenizing position to the end of the target string.
- Because a failure to match the target string returns the rest of the tokenizer string, StringUpTo leaves no easy way to determine if you get a result string because you got a match or because you went to the end of the string. A good technique then may be to follow a StringUpTo call with a NextPosition call to check your result.
