=head1 NAME
Mixin::Linewise::Readers - get linewise readers for strings and filenames
=head1 SYNOPSIS
package Your::Pkg;
use Mixin::Linewise::Readers -readers;
sub read_handle {
my ($self, $handle) = @_;
LINE: while (my $line = $handle->getline) {
next LINE if $line =~ /^#/;
print "non-comment: $line";
}
}
Then:
use Your::Pkg;
Your::Pkg->read_file($filename);
Your::Pkg->read_string($string);
Your::Pkg->read_handle($fh);
=head1 EXPORTS
C<read_file> and C<read_string> are exported by default. Either can be
requested individually, or renamed. They are generated by
L<Sub::Exporter|Sub::Exporter>, so consult its documentation for more
information.
Both can be generated with the option "method" which requests that a method
other than "read_handle" is called with the created IO::Handle.
=head2 read_file
Your::Pkg->read_file($filename);
If generated, the C<read_file> export attempts to open the named file for
reading, and then calls C<read_handle> on the opened handle.
Any arguments after C<$filename> are passed along after to C<read_handle>.
=cut
sub _mk_read_file {
my ($self, $name, $arg) = @_;
my $method = defined $arg->{method} ? $arg->{method} : 'read_handle';
sub {
my ($invocant, $filename) = splice @_, 0, 2;
# Check the file
Carp::croak "no filename specified" unless $filename;
Carp::croak "file '$filename' does not exist" unless -e $filename;
Carp::croak "'$filename' is not a plain file" unless -f _;
my $handle = IO::File->new($filename, '<')
or Carp::croak "couldn't read file '$filename': $!";
$invocant->$method($handle, @_);
}
}
=head2 read_string
Your::Pkg->read_string($string);
If generated, the C<read_string> creates an IO::String handle from the given
string, and then calls C<read_handle> on the opened handle.
Any arguments after C<$string> are passed along after to C<read_handle>.
=cut
sub _mk_read_string {
my ($self, $name, $arg) = @_;
my $method = defined $arg->{method} ? $arg->{method} : 'read_handle';
sub {
my ($invocant, $string) = splice @_, 0, 2;
Carp::croak "no string provided" unless defined $string;
my $handle = IO::String->new(\$string);
$invocant->$method($handle, @_);
}
}
