- Synopsis:
- $afterw(<word> <text>)
- $beforew(<word> <text>)
-
- Technical:
- These functions return their input string, minus all words up to the
- given word ($beforew()) or following the given word ($afterw()). They
- are analogous to $after() and $before(), operating on whole words
- instead of characters. They search only for the first occurrence of the
- given word.
-
- Practical:
- These return the part of the input text that is before or after the
- first instance of the given word. This is probably most useful for
- internal parsing inside scripts; a variable might hold certain
- parameters, of which only certain ones might be useful at a particular
- time. If the given word does not appear in the input text, nothing
- is returned.
-
- Returns:
- afterw: input list after first instance of given word
- beforew: input list before first instance of given word
-
- Examples:
- $afterw(foobar one two foobar my shoe) returns "my shoe"
- $afterw(booya one two foobar my shoe) returns "" (empty string)
- $beforew(foobar one two foobar my shoe) returns "one two"
- $beforew(booya one two foobar my shoe) returns "" (empty string)
