=head1 NAME
Mixin::Linewise::Writers - get linewise writeers for strings and filenames
=head1 SYNOPSIS
package Your::Pkg;
use Mixin::Linewise::Writers -writers;
sub write_handle {
my ($self, $data, $handle) = @_;
$handle->print("datum: $_\n") for @$data;
}
Then:
use Your::Pkg;
Your::Pkg->write_file($data, $filename);
Your::Pkg->write_string($data, $string);
Your::Pkg->write_handle($data, $fh);
=head1 EXPORTS
C<write_file> and C<write_string> are exported by default. Either can be
requested individually, or renamed. They are generated by
L<Sub::Exporter|Sub::Exporter>, so consult its documentation for more
information.
Both can be generated with the option "method" which requests that a method
other than "write_handle" is called with the created IO::Handle.
=head2 write_file
Your::Pkg->write_file($data, $filename);
This method will try to open a new file with the given name. It will then call
C<write_handle> with that handle.
Any arguments after C<$filename> are passed along after to C<write_handle>.
=cut
sub _mk_write_file {
my ($self, $name, $arg) = @_;
my $method = defined $arg->{method} ? $arg->{method} : 'write_handle';
sub {
my ($invocant, $data, $filename) = splice @_, 0, 3;
# Check the file
Carp::croak "no filename specified" unless $filename;
Carp::croak "'$filename' is not a plain file" if -e $filename && ! -f _;
# Write out the file
my $handle = IO::File->new($filename, '>')
or Carp::croak "couldn't write to file '$filename': $!";
$invocant->write_handle($data, $handle, @_);
}
}
=head2 write_string
my $string = Your::Pkg->write_string($data);
C<write_string> will create a new IO::String handle, call C<write_handle> to
write to that handle, and return the resulting string.
Any arguments after C<$data> are passed along after to C<write_handle>.
=cut
sub _mk_write_string {
my ($self, $name, $arg) = @_;
my $method = defined $arg->{method} ? $arg->{method} : 'write_handle';
sub {
my ($invocant, $data) = splice @_, 0, 2;
my $string = '';
my $handle = IO::String->new($string);
$invocant->write_handle($data, $handle, @_);
return $string;
}
}
