- Synopsis:
- $left(<count> <text>)
- $right(<count> <text>)
-
- Technical:
- These functions return a slice of the given length from the input
- string, either from the left side or the right side of the string. The
- functions do no padding, so it is more accurate to say that they will
- return no more than the given number of characters, not necessarily
- exactly the given amount.
-
- Practical:
- The most common use for these functions is fetching a certain number of
- characters from an arbitrary string, where the length is known, but the
- contents are inconsequential.
-
- Returns:
- substring no longer than specified length
-
- Examples:
- $left(5 biklmnopstv) returns "biklm"
- $left(15 biklmnopstv) returns "biklmnopstv"
- $left(-2 biklmnopstv) returns nothing
- $right(5 biklmnopstv) returns "opstv"
