Mixin::Linewise::Writers

NAME

Mixin::Linewise::Writers − get linewise writers for strings and filenames

VERSION

version 0.108

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

"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

  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

  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".
