IO::Tokenized::Scalar - Extension of IO::Scalar allowing tokenized input
my $fh = IO::Tokenized::Scalar->new(); $fh->setparser([num => qr/\d+/], [ident => qr/[a-z_][a-z0-9_]], [op => qr![+*/-]!,\&opname]); $fh->open('tokenfile') || die "Can't open 'tokenfile': $1"; while ($t = $fh->gettoken()) { ... do something smart... } $fh->close();
This is a modified version of IO::Tokenized::File; it has just every occurrence of IO::File replaced by IO::Scalar. The original package is copyright Leo Cacciari; modification by Roel van der Steen <roel-perl@st2x.net>.
IO::Tokenized::Scalar adds the methods provided by IO::Tokenized to IO::Scalar objects. See IO::Tokenized for details about how the tokens are specified and returned.
IO::Tokenized::Scalar inherits both from IO::tokenized and IO::Scalar, so that methods from both classes are available to IO::Tokenized::Scalar objects.
IO::Tokenized::Scalar redefines the following methods:
new([$filename[,@tokens]])
The new method is redefined so as to call both IO::Scalar::new (passing to $filename if it is defined) and IO::Tokenized::new (passing to it the @tokens parameter).
new
IO::Scalar::new
$filename
IO::Tokenized::new
@tokens
open($filename)
The open method from IO::Scalar is redefined so that only opening for input is allowed: requestes for other kind of opening are silently converted to opening for input (this is a bug).
open
IO::Tokenized and IO::Scalar.
