Mixin::Linewise::Writers(3) User Contributed Perl Documentation Mixin::Linewise::Writers(3)

# [SYNOPSIS](#SYNOPSIS)

```
  package Your::Pkg;
  use Mixin::Linewise::Writers -writers;
  sub write_handle {
    my ($self, $data, $handle) = @_;
    $handle->print("datum: $_\n") for @$data;
  }
```

Then:

```
  use Your::Pkg;
  Your::Pkg->write_file($data, $filename);
  Your::Pkg->write_string($data, $string);
  Your::Pkg->write_handle($data, $fh);
```

# [EXPORTS](#EXPORTS)

"write\_file" and "write\_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 "write\_handle" is called with the created IO::Handle.

If given a "binmode" option, any "write\_file" type functions will use that as an IO layer, otherwise, the default is encoding(UTF-8).

```
  use Mixin::Linewise::Writers -writers => { binmode => "raw" };
  use Mixin::Linewise::Writers -writers => { binmode => "encoding(iso-8859-1)" };
```

## [write\_file](#write_file)

```
  Your::Pkg->write_file($data, $filename);
  Your::Pkg->write_file($data, $options, $filename);
```

This method will try to open a new file with the given name. It will then call "write\_handle" with that 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 encoding(UTF-8).

Any arguments after $filename are passed along after to "write\_handle".

## [write\_string](#write_string)

```
  my $string = Your::Pkg->write_string($data);
  my $string = Your::Pkg->write_string(\%option, $data);
```

"write\_string" will create a new handle on the given string, then call "write\_handle" to write to that handle, and return the resulting string. Because handles on strings must be octet-oriented, the string **will contain** **octets**. It will be opened in the default binmode established by importing. (See "EXPORTS", above, and the options, below.)

Any arguments after $data are passed along after to "write\_handle".

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