YAML format backend for Qwiratry, powered by L<YAMLish> C<0.1.3+>
(required for RakuAST compatibility).


Defines C<Qwiratry::Format::YAML::Parse> and
C<Qwiratry::Format::YAML::Render> implementations loaded through
L<Qwiratry::Format.make>.


The parser lowers YAML mappings to hashes, sequences to arrays, scalars to
C<Str>/C<Int>/C<Num>/C<Bool>, and null forms (such as C<~>) to undefined
values. Invalid YAML fails hard (throws) so callers and the format
conformance kit can treat parse errors uniformly.


The renderer emits YAML documents via L<YAMLish>'s C<save-yaml>. Mapping keys
are sorted by default (C<:sorted-keys>, mapped to YAMLish's C<:sorted>) for
deterministic output.


use YAMLish;
use Qwiratry::Format::Base;

class Qwiratry::Format::YAML::Parse is Qwiratry::Format::Base::Parse {

	

Parse YAML text into ordinary Raku data structures using L<YAMLish>.


	method parse(Str $input-string --> Mu) {
		my $parsed = load-yaml($input-string);
		$parsed ~~ Failure
			?? die($parsed.exception)
			!! $parsed
	}
}

class Qwiratry::Format::YAML::Render is Qwiratry::Format::Base::Render {

	

C<render(Mu $data, Associative :%options)>


Render ordinary Raku data structures to YAML text using L<YAMLish>.


C<%options<sorted-keys>> defaults to true and is passed through as
	YAMLish's C<:sorted> flag.


	method render(Mu $data, *%options --> Str) {
		my $sorted-keys = %options<sorted-keys> // True;
		save-yaml($data, :sorted($sorted-keys))
	}
}
