Example
| Description | Examples of possible ways to use string.sub. |
|---|---|
| Used on | |
| Code | teststring = "Hello, world!" // from character 8 to the end print(string.sub(teststring, 8)) // from character 2 to 5 (inclusive) print(string.sub(teststring, 2, 5)) // 6th character from the end, to the end print(string.sub(teststring, -6)) // 6th character from the end to the 5th character from the end print(string.sub(teststring, -6, -5)) // 6th character from the end to the 12th character from the start print(string.sub(teststring, -6, 12)) |
| Output | world! ello |
Additional Notes
- Strings start at 1, meaning string.sub("abc", 1, 1) will return "a", the first character of the string.
- Not supplying a value for 'End' will automatically assume the last position in the string!
