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".
