Mixin::...Readers(3)

okay bestie, welcome to Mixin::...Readers(3) from the User Contributed Perl Documentation corner of the universe 💖 this is the page for getting linewise readers for strings and filenames, and yes it's giving useful.

✨ NAME ✨

Mixin::Linewise::Readers — get linewise readers for strings and filenames 🎀

🦋 VERSION 🦋

version 0.111 ✨

💅 SYNOPSIS 💅

okay so first you set up your package like this:

package Your::Pkg;
use Mixin::Linewise::Readers -readers;

sub read_handle {
  my ($self, $handle) = @_;

  LINE: while (my $line = $handle->getline) {
    next LINE if $line =~ /^#/;

    print "non-comment: $line";
  }
}

Then:

use Your::Pkg;

Your::Pkg->read_file($filename);

Your::Pkg->read_string($string);

Your::Pkg->read_handle($fh);

🌸 PERL VERSION 🌸

This module should work on any version of perl still receiving updates from the Perl 5 Porters. That means it should work on any version of perl released in the last two to three years. So if the most recently released version is v5.40, then this module should work on both v5.40 and v5.38 💖

It may work on older versions of perl, but 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. periodt.

🧚 EXPORTS 🧚

read_file and read_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 read_handle is called with the created IO::Handle.

If given a binmode option, any read_file type functions will use that as an IO layer, otherwise, the default is utf8_strict.

use Mixin::Linewise::Readers -readers => { binmode => "raw" };
use Mixin::Linewise::Readers -readers => { binmode => "encoding(iso-8859-1)" };

🍓 read_file 🍓

Your::Pkg->read_file($filename);
Your::Pkg->read_file(\%options, $filename);

If generated, the read_file export attempts to open the named file for reading, and then calls read_handle on the opened 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 utf8_strict.

Any arguments after $filename are passed along after to read_handle.

🎀 read_string 🎀

Your::Pkg->read_string($string);
Your::Pkg->read_string(\%option, $string);

If generated, the read_string creates a handle on the given string, and then calls read_handle on the opened handle. Because handles on strings must be octet-oriented, the string must contain octets. It will be opened in the default binmode established by importing. (See EXPORTS, above.) 🫶

Any arguments after $string are passed along after to read_handle.

Like read_file, this method can take a leading hashref with one valid argument: binmode.
