NAME
IO::Tokenized::File - Extension of IO::File allowing tokenized input
SYNOPSIS
my
$fh
= IO::Tokenized::File->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...
}
$fh
->
close
();
DESCRIPTION
IO::Tokenized::File adds the methods provided by IO::Tokenized to IO::File objects. See IO::Tokenized for details about how the tokens are specified and returned.
METHODS
IO::Tokenized::File inherits both from IO::tokenized and IO::File, so that methods from both classes are available to IO::Tokenized::File objects.
IO::Tokenized::File redefines the following methods:
new([$filename[,@tokens]])
The
new
method is redefined so as to call bothIO::File::new
(passing to$filename
if it is defined) andIO::Tokenized::new
(passing to it the@tokens
parameter).open($filename)
The
open
method from IO::File is redefined so that only opening for input is allowed: requestes for other kind of opening are silently converted to oepning for input (this is a bug).
