|

This package provides a set of useful predicates to manipulate
|
||||
sequences of characters codes, usually first read in as a line. It is
|
||||
avalailable by loading the library @code{library(lineutils)}.
|
||||

||||

@var{RestOfLine} has the line to the right.

|

@cnindex scan_natural/3
|

Scan the list of codes @var{Line} for a natural number @var{Nat}, zero
|
||||
or a positive integer, and unify @var{RestOfLine} with the remainder
|
||||
of the line.

positive, zero, or negative integer, and unify @var{RestOfLine} with

the remainder of the line.

|

Unify @var{Words} with a set of strings obtained from @var{Line} by
|

using the character codes in @var{Separators} as separators. As an
|
||||
example, consider:
|
||||
@example
|
||||
?- split("Hello * I am free"," *",S).
|
||||
|

S = ["Hello","I","am","free"] ?
