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

VERSION
       version 0.111

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);

PERL VERSION
       This module should work on any version of perl still receiving updates from the Perl 5
       Porters.  This means it should work on any version of perl released in the last two to
       three years.  (That is, if the most recently released version is v5.40, then this module
       should work on both v5.40 and v5.38.)

       Although it may work on older versions of perl, no guarantee is made that the minimum
       required version will not be increased.  The version may be increased for any reason, and
       there is no promise that patches will be accepted to lower the minimum required perl.

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);
         Your::Pkg->read_string(\%option, $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".

       Like "read_file", this method can take a leading hashref with one valid argument:
       "binmode".
