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
See Also:
afterw (6); beforew (6)
