NAME

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

VERSION

version 0.106

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.

If given a "binmode" option, any read_file type functions will use that as an IO layer, otherwise, the default is utf8_strict.

  use Mixin::Linewise::Readers -readers => { binmode => "raw" };
  use Mixin::Linewise::Readers -readers => { binmode => "encoding(iso-8859-1)" };

read_file

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

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

An optional hash reference may be passed before $filename with options. The only valid option currently is binmode, which overrides any default set from use or the built-in utf8_strict.

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

read_string

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

If generated, the read_string creates a handle on the given string, and then calls read_handle on the opened handle. Because handles on strings must be octet-oriented, the string must contain octets. It will be opened in the default binmode established by importing. (See "EXPORTS", above.)

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