- Synopsis:
- $fromw(<word> <list of words>)
- $tow(<word> <list of words>)
-
- Technical:
- These two functions are used to filter a range of words from the given
- input string. The $fromw() function starts at the first occurrence of the
- specified word, and returns it and all that follow it. The $tow()
- function is the opposite, returning all words up to and including the
- search word.
-
- Practical:
- The mnemonic for these functions are "from word" and "to word". The
- most important distinction is that they include the search word in the
- return string, where functions like $afterw() and $beforew() do not.
-
- Returns:
- list of words
-
- Examples:
- $tow(two one two three) returns "one two"
- $tow(four one two three) returns nothing, "four" not in list
- $fromw(two one two three) returns "two three"
- $fromw(four one two three) returns nothing, "four" not in list
