.SH SYNOPSIS
.IX Header "SYNOPSIS"
.Vb 2
\&  package Your::Pkg;
\&  use Mixin::Linewise::Writers \-writers;
\&
\&  sub write_handle {
\&    my ($self, $data, $handle) = @_;
\&
\&    $handle\->print("datum: $_\en") for @$data;

Then:
.PP
.Vb 1
\&  use Your::Pkg;
\&

\&
\&  Your::Pkg\->write_string($data, $string);
\&
\&  Your::Pkg\->write_handle($data, $fh);

.SH EXPORTS
.IX Header "EXPORTS"
\&\f(CW\*(C`write_file\*(C'\fR and \f(CW\*(C`write_string\*(C'\fR are exported by default.  Either can be
requested individually, or renamed.  They are generated by
Sub::Exporter, so consult its documentation for more
information.
.PP
Both can be generated with the option "method" which requests that a method
other than "write_handle" is called with the created IO::Handle.
.PP
If given a "binmode" option, any \f(CW\*(C`write_file\*(C'\fR type functions will use
that as an IO layer, otherwise, the default is \f(CWencoding(UTF\-8)\fR.
.PP
.Vb 2
\&  use Mixin::Linewise::Writers \-writers => { binmode => "raw" };
\&  use Mixin::Linewise::Writers \-writers => { binmode => "encoding(iso\-8859\-1)" };
.Ve
.SS write_file
.IX Subsection "write_file"
.Vb 2
\&  Your::Pkg\->write_file($data, $filename);
\&  Your::Pkg\->write_file($data, $options, $filename);
.Ve
.PP
This method will try to open a new file with the given name.  It will then call
\&\f(CW\*(C`write_handle\*(C'\fR with that handle.
.PP
An optional hash reference may be passed before \f(CW$filename\fR with options.
The only valid option currently is \f(CW\*(C`binmode\*(C'\fR, which overrides any
default set from \f(CW\*(C`use\*(C'\fR or the built\-in \f(CWencoding(UTF\-8)\fR.
.PP
Any arguments after \f(CW$filename\fR are passed along after to \f(CW\*(C`write_handle\*(C'\fR.
.SS write_string
.IX Subsection "write_string"
.Vb 2
\&  my $string = Your::Pkg\->write_string($data);
\&  my $string = Your::Pkg\->write_string(\e%option, $data);
.Ve
.PP
\&\f(CW\*(C`write_string\*(C'\fR will create a new handle on the given string, then call
\&\f(CW\*(C`write_handle\*(C'\fR to write to that handle, and return the resulting string.
Because handles on strings must be octet\-oriented, the string \fBwill contain
octets\fR.  It will be opened in the default binmode established by importing.
(See "EXPORTS", above, and the options, below.)
.PP
Any arguments after \f(CW$data\fR are passed along after to \f(CW\*(C`write_handle\*(C'\fR.
.PP
Like \f(CW\*(C`write_file\*(C'\fR, this method can take a leading hashref with one valid
argument: \f(CW\*(C`binmode\*(C'\fR.
