NAME

Mixin::Linewise::Readers - get linewise readers for strings and filenames

VERSION

version 0.004

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);

EXPORTS

"read_file" and "read_string" are exported by default. Either can be requested individually, or renamed. They are generated by 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.

read_file

  Your::Pkg->read_file($filename);

If generated, the "read_file" export attempts to open the named file for reading, and then calls "read_handle" on the opened handle.

Any arguments after $filename are passed along after to "read_handle".

read_string

  Your::Pkg->read_string($string);

If generated, the "read_string" creates an IO::String handle from the given string, and then calls "read_handle" on the opened handle.

Any arguments after $string are passed along after to "read_handle".
