CPAN::Meta::YAML(3pm)

CPAN::Meta::YAML 💅

Okay bestie, this is the CPAN::Meta::YAML(3pm) page from the Perl Programmers Reference Guide — and it's lowkey a very focused little module. We're talking read/write a subset of YAML specifically for CPAN Meta files, no cap. The version is 0.020, and it's giving very purpose-built energy. Not me being obsessed with a module this focused. Slay.

✨ NAME ✨

CPAN::Meta::YAML — Read and write a subset of YAML for CPAN Meta files.

🎀 VERSION 🎀

version 0.020

🦋 SYNOPSIS 🦋

Here's the group-chat demo, exactly as the page lays it out:

use CPAN::Meta::YAML;

# reading a META file
open $fh, "<:utf8", "META.yml";
$yaml_text = do { local $/; <$fh> };
$yaml = CPAN::Meta::YAML->read_string($yaml_text)
  or die CPAN::Meta::YAML->errstr;

# finding the metadata
$meta = $yaml->[0];

# writing a META file
$yaml_text = $yaml->write_string
  or die CPAN::Meta::YAML->errstr;
open $fh, ">:utf8", "META.yml";
print $fh $yaml_text;

🌸 DESCRIPTION 🌸

Okay so this module implements a subset of the YAML specification for use in reading and writing CPAN metadata files like META.yml and MYMETA.yml. It should not be used for any other general YAML parsing or generation task. Periodt. The way that it stays in its lane is the whole point — it's main character energy, but only for CPAN Meta files. It ate and left no crumbs. Vibe check: specialist, not a multitasker.

NOTE: META.yml (and MYMETA.yml) files should be UTF-8 encoded. Users are responsible for proper encoding and decoding. In particular, the read and write methods do not support UTF-8 and should not be used. This is important, bestie — those methods literally do not support UTF-8 and should not be used.

💜 SUPPORT 💜

This module is currently derived from YAML::Tiny by Adam Kennedy. If there are bugs in how it parses a particular META.yml file, ngl, please file a bug report in the YAML::Tiny bugtracker: <https://github.com/Perl-Toolchain-Gang/YAML-Tiny/issues>.
