- Synopsis:
- $leftw(<count> <word list>)
- $rightw(<count> <word list>)
-
- Technical:
- These functions are used to return a slice of the input list, from either
- the beginning or end of the list. It returns the indicated number of
- words from the beginning or the end of the list.
-
- Practical:
- This is mostly useful when you know you always want to get a certain
- number of starting or ending words in a list, regardless of what they
- are. They are analogous to $left() and $right(), except they operate on
- whole words instead of characters.
-
- Returns:
- list of words from beginning or end of word list
-
- Examples:
- $leftw(2 hello there how are you?) returns "hello there"
- $leftw(-1 hello there bob) returns nothing
- $leftw(7 hello there bob) returns "hello there bob"
- $rightw(2 hello there how are you?) returns "are you?"
