NAME
Lexical::select - provides a lexically scoped currently selected
filehandle
VERSION
version 0.10
SYNOPSIS
use Lexical::select;
open my $fh, '>', 'fubar' or die "Oh noes!\n";
{
my $lxs = lselect $fh;
print "Something wicked goes to \$fh \n";
}
print "Back on STDOUT\n";
DESCRIPTION
Changing the currently selected filehandle with "select" and changing it
back to the previously selected filehandle can be slightly tedious.
Wouldn't it be great to have something handle this boilerplate,
especially in lexical scopes.
This is where Lexical::select comes in.
Lexical::select provides the "lselect" function. As demonstrated in the
"SYNOPSIS", "lselect" will change the currently selected filehandle to
the filehandle of your choice for the duration of the enclosing lexical
scope.
It should be noted that the duration of the selected filehandle is
limited to the lexical scope, not the effects of the selected
filehandle.
FUNCTIONS
Functions exported by default.
"lselect"
Takes one parameter, a "filehandle" that will become the currently
selected filehandle for the duration of the enclosing scope.
Returns an object, which provides the "restore" method.
You can then either "restore" the currently selected filehandle back
manually or let the object fall out of scope, which automagically
restores.
METHODS
"restore"
Explicitly restores the currently selected filehandle back to the
original filehandle. This is called automagically when the object is
"DESTROY"ed, for instance when the object goes out of scope.
