Mixin::Linewise::Writers - get linewise writers for strings and filenames
version 0.111
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, $fh);
This module should work on any version of perl still receiving updates from the Perl 5 Porters. This means it should work on any version of perl released in the last two to three years. (That is, if the most recently released version is v5.40, then this module should work on both v5.40 and v5.38.)
Although it may work on older versions of perl, no guarantee is made that the minimum required version will not be increased. The version may be increased for any reason, and there is no promise that patches will be accepted to lower the minimum required perl.
write_file and write_string are exported by default. Either can be requested individually, or renamed. They are generated by Sub::Exporter, so consult its documentation for more information.
write_file
write_string
Both can be generated with the option "method" which requests that a method other than "write_handle" is called with the created IO::Handle.
If given a "binmode" option, any write_file type functions will use that as an IO layer, otherwise, the default is encoding(UTF-8).
encoding(UTF-8)
use Mixin::Linewise::Writers -writers => { binmode => "raw" }; use Mixin::Linewise::Writers -writers => { binmode => "encoding(iso-8859-1)" };
Your::Pkg->write_file($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.
write_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).
$filename
binmode
use
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.
$data
Like write_file, this method can take a leading hashref with one valid argument: binmode.
