Mixin::Linewise::Writers - get linewise writers for strings and filenames
version 0.108
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, $fh);
"write_file" and "write_string" are exported by default. Either can be requested individually, or renamed. They are generated by Sub::Exporter, so consult its documentation for more information.
Both can be generated with the option "method" which requests that a method other than "write_handle" is called with the created IO::Handle.
If given a "binmode" option, any "write_file" type functions will use that as an IO layer, otherwise, the default is "encoding(UTF-8)".
use Mixin::Linewise::Writers -writers => { binmode => "raw" };
use Mixin::Linewise::Writers -writers => { binmode => "encoding(iso-8859-1)" };
Your::Pkg->write_file($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".
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".
