NAME

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

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".

NAME

       Sub::Exporter::ForMethods - helper routines for using Sub::Exporter to build methods

VERSION

       version 0.091970

SYNOPSIS

       In an exporting library:

	 package Method::Builder;

	 use Sub::Exporter::ForMethods qw(method_installer);

	 use Sub::Exporter -setup => {
	   exports   => [ method => '_method_generator' ],
	   installer => method_installer,
	 };

	 sub _method_generator {
	   my ($self, $name, $arg, $col) = @_;
	   return sub { ... };
	 };

       In an importing library:

	 package Vehicle::Autobot;
	 use Method::Builder method => { -as => 'transform' };

DESCRIPTION

       The synopsis section, above, looks almost indistinguishable from any other use of Sub::Exporter, apart from the use of "method_installer".
       It is nearly indistinguishable in behavior, too.  The only change is that subroutines exported from Method::Builder into named slots in
       Vehicle::Autobot will be wrapped in a subroutine called "Vehicle::Autobot::transform".  This will insert a named frame into stack traces to
       aid in debugging.

       More importantly (for the author, anyway), they will not be removed by namespace::autoclean.  This makes the following code work:

	 package MyLibrary;

	 use Math::Trig qw(tan);	 # uses Exporter.pm
	 use String::Truncate qw(trunc); # uses Sub::Exporter's defaults

	 use Sub::Exporter::ForMethods qw(method_installer);
	 use Mixin::Linewise { installer => method_installer }, qw(read_file);

	 use namespace::autoclean;

	 ...

	 1;

       After MyLibrary is compiled, "namespace::autoclean" will remove "tan" and "trunc" as foreign contaminants, but will leave "read_file" in
       place.  It will also remove "method_installer", an added win.

EXPORTS

       Sub::Exporter::ForMethods offers only one routine for export, and it may also be called by its full package name:

   method_installer
       This routine returns an installer suitable for use as the "installer" argument to Sub::Exporter.  It updates the "@to_export" argument to
       wrap all code that will be installed by name in a named subroutine, then passes control to the default Sub::Exporter installer.
