YAML Schema examples in YAML::PP and other Perl ModulesYAML Test Suite Test Cases
| Schema examples
| Schema comparison
The Perl Module YAML::PP implements YAML 1.2.
You can choose between several Schemas.
The following table shows which strings result in which native data, depending
on the Schema (or other YAML module) you use.
For each of the Schemas and modules, the first column is the type,
and the second shows how the data is encoded into YAML again.
Note that the YAML 1.2 JSON Schema is not exactly like the official schema,
as all strings would have to be quoted.

This module uses Dist::Zilla for creating releases, but you should
be able to develop and test it without Dist::Zilla.
## Commits
I try to follow these guidelines:
* Git commits
* Short commit message headline (if possible, up to 60 characters)
* Blank line before message body
* Message should be like: "Add foo ...", "Fix ..."
* If you need to do formatting changes like indentation, put them
into their own commit
* Git workflow
* Rebase every branch before merging it with --no-ff. Rebasing your
pull request to current master helps me merging it.
* No merging master into branches - try to rebase always
* User branches might be heavily rebased/reordered/squashed because
I like a clean history
## Code
* No Tabs please
* No trailing whitespace please
* 4 spaces indentation
* Look at existing code for formatting ;-)
## Testing
prove -lr t
To include the tests from the yaml-test-suite, checkout the test-suite
branch like this:
git branch test-suite --track origin/test-suite
git worktree add test-suite test-suite
There is also a Makefile.dev and a utility script dev.sh
source dev.sh
dmake testp # parallel testing
You can check test coverage with
make -f Makefile.dev cover
# or
dmake cover
## Contact
Email: tinita at cpan.org
IRC: tinita on freenode and irc.perl.org
Chances are good that contacting me on IRC is the fastest way.

YAML::PP::Schema::Tie::IxHash - (Deprecated) Schema for serializing ordered hashes
=head1 SYNOPSIS
use YAML::PP;
use Tie::IxHash;
my $yp = YAML::PP->new( schema => [qw/ + Tie::IxHash /] );
tie(my %ordered, 'Tie::IxHash');
%ordered = (
U => 2,
B => 52,
);
my $yaml = $yp->dump_string(\%ordered);
# Output:
---
U: 2
B: 52
=head1 DESCRIPTION
This is deprecated. See the new option C in L.
This schema allows you to dump ordered hashes which are tied to
L.
This code is pretty new and experimental.
It is not yet implemented for loading yet, so for now you have to tie
the hashes yourself.
Examples:

YAML::PP::Schema::Include - Include YAML files
=head1 SYNOPSIS
# /path/to/file.yaml
# ---
# included: !include include/file2.yaml
# /path/to/include/file2.yaml
# ---
# a: b
my $include = YAML::PP::Schema::Include->new;
my $yp = YAML::PP->new( schema => ['+', $include] );
# we need the original YAML::PP object for getting the current filename
# and for loading another file
$include->yp($yp);
my ($data) = $yp->load_file("/path/to/file.yaml");
# The result will be:
$data = {
included => { a => 'b' }
};
Allow absolute filenames and upwards C<'..'>:
my $include = YAML::PP::Schema::Include->new(
allow_absolute => 1, # default: 0
);
Specify paths to search for includes:
my @include_paths = ("/path/to/include/yaml/1", "/path/to/include/yaml/2");
my $include = YAML::PP::Schema::Include->new(
paths => \@include_paths,
);
my $yp = YAML::PP->new( schema => ['+', $include] );
$include->yp($yp);
# /path/to/include/yaml/1/file1.yaml
# ---
# a: b

- included: !include file1.yaml
EOM
my ($data) = $yp->load_string($yaml);
=head1 DESCRIPTION
This plugin allows you to split a large YAML file into smaller ones.
You can then include these files with the C tag.
It will search for the specified filename relative to the currently processed
filename.
You can also specify the paths where to search for files to include. It iterates
through the paths and returns the first filename that exists.
By default, only relative paths are allowed. Any C<../> in the path will be
removed. You can change that behaviour by setting the option C
to true.
If the included file contains more than one document, only the first one
will be included.
I will probably add a possibility to return all documents as an arrayref.
The included YAML file will be loaded by creating a new L object
with the schema from the existing object. This way you can recursively include
files.
You can even reuse the same include via an alias:
---
invoice:
shipping address: &address !include address.yaml
billing address: *address
Circular includes will be detected, and will be fatal.
It's possible to specify what to do with the included file:
my $include = YAML::PP::Schema::Include->new(
loader => sub {
my ($yp, $filename);
if ($filename =~ m/\.txt$/) {
# open file and just return text
}
else {
# default behaviour
return $yp->load_file($filename);
}
},
);
For example, RAML defines an C tag which depends on the file
content. If it contains a special RAML directive, it will be loaded as
YAML, otherwise the content of the file will be included as a string.
So with this plugin you are able to read RAML specifications.

=head1 DESCRIPTION
See L for the specification.
Quote:
"Specify one or more mappings to be merged with the current one.
The C<< << >> merge key is used to indicate that all the keys of one or more
specified maps should be inserted into the current map. If the value associated
with the key is a single mapping node, each of its key/value pairs is inserted
into the current mapping, unless the key already exists in it. If the value
associated with the merge key is a sequence, then this sequence is expected to
contain mapping nodes and each of these nodes is merged in turn according to its
order in the sequence. Keys in mapping nodes earlier in the sequence override
keys specified in later mapping nodes."
The implementation of this in a generic way is not trivial, because we also
have to handle duplicate keys, and YAML::PP allows you to write your own
handler for processing mappings.
So the inner API of that is not stable at this point.
Note that if you enable this schema, a plain scalar `<<` will be seen as
special anywhere in your document, so if you want a literal `<<`, you have
to put it in quotes.
Note that the performed merge is not a "deep merge". Only top-level keys are
merged.

=head1 NAME
YAML::PP::Schema::Perl - Schema for serializing perl objects and special types
=head1 SYNOPSIS
use YAML::PP;
# This can be dangerous when loading untrusted YAML!
my $yp = YAML::PP->new( schema => [qw/ + Perl /] );
# or
my $yp = YAML::PP->new( schema => [qw/ Core Perl /] );
my $yaml = $yp->dump_string(sub { return 23 });
# loading code references
# This is very dangerous when loading untrusted YAML!!
my $yp = YAML::PP->new( schema => [qw/ + Perl +loadcode /] );
my $code = $yp->load_string(<<'EOM');
--- !perl/code |
{
use 5.010;
my ($name) = @_;
say "Hello $name!";
}
EOM
$code->("Ingy");
=head1 DESCRIPTION
This schema allows you to load and dump perl objects and special types.
Please note that loading objects of arbitrary classes can be dangerous
in Perl. You have to load the modules yourself, but if an exploitable module
is loaded and an object is created, its C method will be called
when the object falls out of scope. L is an example that can
be exploitable and might remove arbitrary files.
Dumping code references is on by default, but not loading (because that is
easily exploitable since it's using string C).
=head2 Tag Styles
You can define the style of tags you want to support:
my $yp_perl_two_one = YAML::PP->new(
schema => [qw/ + Perl tags=!!perl+!perl /],
);
=over
=item C (default)
Only C tags are supported.
=item C
Only C tags are supported.
=item C
Both C and C are supported when loading. When dumping,
C is used.
=item C
Both C and C are supported when loading. When dumping,
C is used.
=back
L.pm, L and L are using C when dumping.
L.pm and L are supporting both C and
C when loading. L currently only supports the latter.
=head2 Allow only certain classes
Since v0.017
Blessing arbitrary objects can be dangerous. Maybe you want to allow blessing
only specific classes and ignore others. For this you have to instantiate
a Perl Schema object first and use the C option.
Currently it only allows a list of strings:
my $perl = YAML::PP::Schema::Perl->new(
classes => ['Foo', 'Bar'],
);
my $yp = YAML::PP::Perl->new(
schema => [qw/ + /, $perl],
);
Allowed classes will be loaded and dumped as usual. The others will be ignored.
If you want to allow no objects at all, pass an empty array ref.

YAML:

=over
=item new
my $perl = YAML::PP::Schema::Perl->new(
tags => "!perl",
classes => ['MyClass'],
loadcode => 1,
dumpcode => 1,
);
The constructor recognizes the following options:
=over
=item tags
Default: 'C'
See L<"Tag Styles">
=item classes
Default: C
Since: v0.017
Accepts an array ref of class names
=item loadcode
Default: 0
=item dumpcode
Default: 1
my $yp = YAML::PP->new( schema => [qw/ + Perl -dumpcode /] );
=back
=item register
A class method called by L
=item construct_ref, represent_ref
Perl variables of the type C are represented in yaml like this:
--- !perl/ref
=:
a: 1
C returns the perl data:
my $data = YAML::PP::Schema::Perl->construct_ref([ '=', { some => 'data' } );
my $data = \{ a => 1 };
C turns a C variable into a YAML mapping:
my $data = YAML::PP::Schema::Perl->represent_ref(\{ a => 1 });
my $data = { '=' => { a => 1 } };
=item construct_scalar, represent_scalar
Perl variables of the type C are represented in yaml like this:
--- !perl/scalar
=: string
C returns the perl data:
my $data = YAML::PP::Schema::Perl->construct_ref([ '=', 'string' );
my $data = \'string';
C turns a C variable into a YAML mapping:
my $data = YAML::PP::Schema::Perl->represent_scalar(\'string');
my $data = { '=' => 'string' };
=item construct_regex, represent_regex
C returns a C object from the YAML string:
my $qr = YAML::PP::Schema::Perl->construct_regex('foo.*');
C returns a string representing the regex object:
my $string = YAML::PP::Schema::Perl->represent_regex(qr{...});
=item evaluate_code, represent_code
C returns a code reference from a string. The string must
start with a C<{> and end with a C<}>.
my $code = YAML::PP::Schema::Perl->evaluate_code('{ return 23 }');
C returns a string representation of the code reference
with the help of B::Deparse:
my $string = YAML::PP::Schema::Perl->represent_code(sub { return 23 });
=item construct_glob, represent_glob
C returns a glob from a hash.
my $glob = YAML::PP::Schema::Perl->construct_glob($hash);
C returns a hash representation of the glob.
my $hash = YAML::PP::Schema::Perl->represent_glob($glob);
=item object
Does the same as C:
my $object = YAML::PP::Schema::Perl->object($data, $class);

=head1 NAME
YAML::PP::Schema::JSON - YAML 1.2 JSON Schema
=head1 SYNOPSIS
my $yp = YAML::PP->new( schema => ['JSON'] );
my $yp = YAML::PP->new( schema => [qw/ JSON empty=str /] );
my $yp = YAML::PP->new( schema => [qw/ JSON empty=null /] );
=head1 DESCRIPTION
With this schema, the resolution of plain values will work like in JSON.
Everything that matches a special value will be loaded as such, other plain
scalars will be loaded as strings.
Note that this is different from the official YAML 1.2 JSON Schema, where all
strings have to be quoted.
Here you can see all Schemas and examples implemented by YAML::PP:
L
Official Schema: L
=head1 CONFIGURATION
The official YAML 1.2 JSON Schema wants all strings to be quoted.
YAML::PP currently does not require that (it might do this optionally in
the future).
That means, there are no empty nodes allowed in the official schema. Example:
---
key:
The default behaviour of YAML::PP::Schema::JSON is to return an empty string,
so it would be equivalent to:
---
key: ''
You can configure it to resolve this as C:
my $yp = YAML::PP->new( schema => [qw/ JSON empty=null /] );
This way it is equivalent to:
---
key: null
The default is:
my $yp = YAML::PP->new( schema => [qw/ JSON empty=str /] );
=head1 METHODS

=head1 NAME
YAML::PP::Constructor - Constructing data structure from parsing events
=head1 METHODS
=over
=item new
The Constructor constructor
my $constructor = YAML::PP::Constructor->new(
schema => $schema,
cyclic_refs => $cyclic_refs,
);
=item init
Resets any data being used during construction.
$constructor->init;
=item document_start_event, document_end_event, mapping_start_event, mapping_end_event, sequence_start_event, sequence_end_event, scalar_event, alias_event, stream_start_event, stream_end_event
These methods are called from L:
$constructor->document_start_event($event);
=item anchors, set_anchors
Helper for storing anchors during construction
=item docs, set_docs
Helper for storing resulting documents during construction
=item stack, set_stack
Helper for storing data during construction
=item cyclic_refs, set_cyclic_refs
Option for controlling the behaviour when finding circular references
=item schema, set_schema
Holds a L object
=item stringify_complex
When constructing a hash and getting a non-scalar key, this method is
used to stringify the key.
It uses a terse Data::Dumper output. Other modules, like L, use
the default stringification, C for example.

=head1 NAME
YAML::PP::Emitter - Emitting events
=head1 SYNOPSIS
my $emitter = YAML::PP::Emitter->new(
indent => 4,
);
$emitter->init;
$emitter->stream_start_event;
$emitter->document_start_event({ implicit => 1 });
$emitter->sequence_start_event;
$emitter->scalar_event({ value => $input, style => $style });
$emitter->sequence_end_event;
$emitter->document_end_event({ implicit => 1 });
$emitter->stream_end_event;
my $yaml = $emitter->writer->output;
$emitter->finish;
=head1 DESCRIPTION
The emitter emits events to YAML. It provides methods for each event
type. The arguments are mostly the same as the events from L.
=head1 METHODS
=over
=item new
my $emitter = YAML::PP::Emitter->new(
indent => 4,
);
Constructor. Currently takes these options:
=over
=item indent
=item writer
=back
=item stream_start_event, stream_end_event, document_start_event, document_end_event, sequence_start_event, sequence_end_event, mapping_start_event, mapping_end_event, scalar_event, alias_event
=item indent, set_indent
Getter/setter for number of indentation spaces.
TODO: Currently sequences are always zero-indented.
=item writer, set_writer
Getter/setter for the writer object. By default L.
You can pass your own writer if you want to output the resulting YAML yourself.
=item init
Initialize
=item finish
=back

YAML::PP::Perl - Convenience module for loading and dumping Perl objects
=head1 SYNOPSIS
use YAML::PP::Perl;
my @docs = YAML::PP::Perl->new->load_string($yaml);
my @docs = YAML::PP::Perl::Load($yaml);
# same as
use YAML::PP;
my $yp = YAML::PP->new( schema => [qw/ Core Perl /] );
my @docs = $yp->load_string($yaml);
=head1 DESCRIPTION
This is just for convenience. It will create a YAML::PP object using the
default schema (C) and the L schema.
See L for documentation.
=head1 METHODS
=over
=item Load, Dump, LoadFile, DumpFile
These work like the functions in L, just adding the C schema.
=item new
Constructor, works like in L, just adds the C schema to the
list of arguments.

Some utility scripts, mostly useful for debugging:
# Load YAML into a data structure and dump with Data::Dumper

# Load and Dump
yamlpp-load-dump < file.yaml
# Print the events from the parser in yaml-test-suite format
yamlpp-events < file.yaml
# Parse and emit events directly without loading
yamlpp-parse-emit < file.yaml
# Create ANSI colored YAML. Can also be useful for invalid YAML, showing

yamlpp-highlight < file.yaml
=head1 DESCRIPTION
YAML::PP is a modular YAML processor.
It aims to support C and C. See L.
Some (rare) syntax elements are not yet supported and documented below.
YAML is a serialization language. The YAML input is called "YAML Stream".
A stream consists of one or more "Documents", separated by a line with a
document start marker C<--->. A document optionally ends with the document
end marker C<...>.
This allows one to process continuous streams additionally to a fixed input
file or string.
The YAML::PP frontend will currently load all documents, and return only
the first if called with scalar context.
The YAML backend is implemented in a modular way that allows one to add
custom handling of YAML tags, perl objects and data types. The inner API
is not yet stable. Suggestions welcome.
You can check out all current parse and load results from the
yaml-test-suite here:

=head1 METHODS
=head2 new
my $ypp = YAML::PP->new;
# use YAML 1.2 Failsafe Schema
my $ypp = YAML::PP->new( schema => ['Failsafe'] );
# use YAML 1.2 JSON Schema
my $ypp = YAML::PP->new( schema => ['JSON'] );
# use YAML 1.2 Core Schema
my $ypp = YAML::PP->new( schema => ['Core'] );
# Die when detecting cyclic references
my $ypp = YAML::PP->new( cyclic_refs => 'fatal' );
my $ypp = YAML::PP->new(
boolean => 'perl',
schema => ['Core'],
cyclic_refs => 'fatal',
indent => 4,
header => 1,
footer => 0,
version_directive => 0,
require_footer => 0,
max_depth => 512,
);
Options:
=over
=item boolean
Values: C (currently default), C, C, C
This option is for loading and dumping.
In case of perl 5.36 and later, builtin booleans should work out of the box
(since YAML::PP >= 0.38.0).
print YAML::PP->new->dump_string([ builtin::true, !1 ]);
# ---
# - true
# - false
For earlier perl versions, you can use "pseudo" booleans like documented
in the following examples.
# load/dump booleans via boolean.pm
my $ypp = YAML::PP->new( boolean => 'boolean' );
# load/dump booleans via JSON::PP::true/false
my $ypp = YAML::PP->new( boolean => 'JSON::PP' );
You can also specify more than one class, comma separated.
This is important for dumping.
boolean => 'JSON::PP,boolean'
Booleans will be loaded as JSON::PP::Booleans, but when dumping, also
'boolean' objects will be recognized
boolean => 'JSON::PP,*'
Booleans will be loaded as JSON::PP::Booleans, but when dumping, all
currently supported boolean classes will be recognized
boolean => '*'
Booleans will be loaded as perl booleans, but when dumping, all
currently supported boolean classes will be recognized
boolean => ''
Booleans will be loaded as perl booleans, but when dumping, nothing
will be recognized as booleans.
This option is for backwards compatibility for perl versions < 5.36,
if you rely on [!!1, !1] being dumped as [1, ''].
The option C was introduced when experimental boolean
support was added to perl 5.36. Since it will not be experimental anymore
in perl 5.40 \o/ the option is deprecated and the same as C.
=item schema
Default: C<['Core']>
This option is for loading and dumping.
Array reference. Here you can define what schema to use.
Supported standard Schemas are: C, C, C, C.
To get an overview how the different Schemas behave, see
L
Additionally you can add further schemas, for example C.
=item cyclic_refs
Default: C (since 0.037)
Before the default was C, but this can lead to memory leaks
when loading on untrusted data, so it was changed to C by default.
This option is for loading only.
Defines what to do when a cyclic reference is detected when loading.
# fatal - die
# warn - Just warn about them and replace with undef
# ignore - replace with undef
# allow - Default
=item duplicate_keys
Default: 0
Since version 0.027
This option is for loading.
The YAML Spec says duplicate mapping keys should be forbidden.
When set to true, duplicate keys in mappings are allowed (and will overwrite
the previous key).
When set to false, duplicate keys will result in an error when loading.
This is especially useful when you have a longer mapping and don't see
the duplicate key in your editor:
---
a: 1
b: 2
# .............
a: 23 # error
=item indent
Default: 2
This option is for dumping.
Use that many spaces for indenting
=item width
Since version 0.025
Default: 80
This option is for dumping.
Maximum columns when dumping.
This is only respected when dumping flow collections right now.
in the future it will be used also for wrapping long strings.
=item header
Default: 1
This option is for dumping.
Print document header C<--->
=item footer
Default: 0
Since version v0.39
This option is for dumping.
Print document footer C<...>
=item require_footer
Default: 0
Will require a C<...> at the end of each document.
This can be useful in a context where you want to make sure you received
the complete content, for example over network.
# Good
---
a: 1
...
---
a: 2
...
# Bad
---
a: 1
---
a: 2
=item max_depth
Since version v0.40
default: 512
Loading deeply nested, but still small YAML documents, like
[[[[[[[[[[...]]]]]]]]]]
can be significantly slower than a "normal" document with the same size.
By default the depth is limited to 512, which should be more than enough
for 99% of the use cases.
=item yaml_version
Since version 0.020
This option is for loading and dumping.
Default: C<1.2>
Note that in this case, a directive C<%YAML 1.1> will basically be ignored
and everything loaded with the C<1.2 Core> Schema.
If you want to support both YAML 1.1 and 1.2, you have to specify that, and the
schema (C or C) will be chosen automatically.
my $yp = YAML::PP->new(
yaml_version => ['1.2', '1.1'],
);
This is the same as
my $yp = YAML::PP->new(
schema => ['+'],
yaml_version => ['1.2', '1.1'],
);
because the C<+> stands for the default schema per version.
When loading, and there is no C<%YAML> directive, C<1.2> will be considered
as default, and the C schema will be used.
If there is a C<%YAML 1.1> directive, the C schema will be used.
Of course, you can also make C<1.1> the default:
my $yp = YAML::PP->new(
yaml_version => ['1.1', '1.2'],
);
You can also specify C<1.1> only:
my $yp = YAML::PP->new(
yaml_version => ['1.1'],
);
In this case also documents with C<%YAML 1.2> will be loaded with the C
schema.
=item version_directive
Since version 0.020
This option is for dumping.
Default: 0
Print Version Directive C<%YAML 1.2> (or C<%YAML 1.1>) on top of each YAML
document. It will use the first version specified in the C option.
=item preserve
Since version 0.021
Default: false
This option is for loading and dumping.
Preserving scalar styles is still experimental.
use YAML::PP::Common qw/ :PRESERVE /;
# Preserve the order of hash keys
my $yp = YAML::PP->new( preserve => PRESERVE_ORDER );
# Preserve the quoting style of scalars
my $yp = YAML::PP->new( preserve => PRESERVE_SCALAR_STYLE );
# Preserve block/flow style (since 0.024)
my $yp = YAML::PP->new( preserve => PRESERVE_FLOW_STYLE );
# Preserve alias names (since 0.027)
my $yp = YAML::PP->new( preserve => PRESERVE_ALIAS );
# Combine, e.g. preserve order and scalar style
my $yp = YAML::PP->new( preserve => PRESERVE_ORDER | PRESERVE_SCALAR_STYLE );
Do NOT rely on the internal implementation of it.
If you load the following input:
---
z: 1
a: 2
---
- plain
- 'single'
- "double"
- |
literal
- >
folded
---
block mapping: &alias
flow sequence: [a, b]
same mapping: *alias
flow mapping: {a: b}
with this code:
my $yp = YAML::PP->new(
preserve => PRESERVE_ORDER | PRESERVE_SCALAR_STYLE
| PRESERVE_FLOW_STYLE | PRESERVE_ALIAS
);
my ($hash, $styles, $flow) = $yp->load_file($file);
$yp->dump_file($hash, $styles, $flow);
Then dumping it will return the same output.
Note that YAML allows repeated definition of anchors. They cannot be preserved
with YAML::PP right now. Example:
---
- &seq [a]
- *seq
- &seq [b]
- *seq
Because the data could be shuffled before dumping again, the anchor definition
could be broken. In this case repeated anchor names will be discarded when
loading and dumped with numeric anchors like usual.
Implementation:
When loading, hashes will be tied to an internal class
(C) that keeps the key order.
Scalars will be returned as objects of an internal class
(C) with overloading. If you assign to such
a scalar, the object will be replaced by a simple scalar.
# assignment, style gets lost
$styles->[1] .= ' append';
You can also pass C<1> as a value. In this case all preserving options will be
enabled, also if there are new options added in the future.
There are also methods to create preserved nodes from scratch. See the
C L<"METHODS"> below.

=head2 load_string
my $doc = $ypp->load_string("foo: bar");
my @docs = $ypp->load_string("foo: bar\n---\n- a");
Input should be Unicode characters.
So if you read from a file, you should decode it, for example with
C.
Note that in scalar context, C and C return the first
document (like L), while L and L return the
last.
=head2 load_file
my $doc = $ypp->load_file("file.yaml");
my @docs = $ypp->load_file("file.yaml");
Strings will be loaded as unicode characters.
=head2 dump_string
my $yaml = $ypp->dump_string($doc);
my $yaml = $ypp->dump_string($doc1, $doc2);
my $yaml = $ypp->dump_string(@docs);
Input strings should be Unicode characters.
Output will return Unicode characters.
So if you want to write that to a file (or pass to YAML::XS, for example),
you typically encode it via C.
=head2 dump_file
$ypp->dump_file("file.yaml", $doc);
$ypp->dump_file("file.yaml", $doc1, $doc2);
$ypp->dump_file("file.yaml", @docs);
Input data should be Unicode characters.
=head2 dump
This will dump to a predefined writer. By default it will just use the
L and output a string.
my $writer = MyWriter->new(\my $output);
my $yp = YAML::PP->new(
writer => $writer,
);
$yp->dump($data);
=head2 preserved_scalar
Since version 0.024
Experimental. Please report bugs or let me know this is useful and works.
You can define a certain scalar style when dumping data.
Figuring out the best style is a hard task and practically impossible to get
it right for all cases. It's also a matter of taste.
use YAML::PP::Common qw/ PRESERVE_SCALAR_STYLE YAML_LITERAL_SCALAR_STYLE /;
my $yp = YAML::PP->new(
preserve => PRESERVE_SCALAR_STYLE,
);
# a single linebreak would normally be dumped with double quotes: "\n"
my $scalar = $yp->preserved_scalar("\n", style => YAML_LITERAL_SCALAR_STYLE );
my $data = { literal => $scalar };
my $dump = $yp->dump_string($data);
# output
---
literal: |+
...
=head2 preserved_mapping, preserved_sequence
Since version 0.024
Experimental. Please report bugs or let me know this is useful and works.
With this you can define which nodes are dumped with the more compact flow
style instead of block style.
If you add C to the C option, it will also keep the
order of the keys in a hash.
use YAML::PP::Common qw/
PRESERVE_ORDER PRESERVE_FLOW_STYLE
YAML_FLOW_MAPPING_STYLE YAML_FLOW_SEQUENCE_STYLE
/;
my $yp = YAML::PP->new(
preserve => PRESERVE_FLOW_STYLE | PRESERVE_ORDER
);
my $hash = $yp->preserved_mapping({}, style => YAML_FLOW_MAPPING_STYLE);
# Add values after initialization to preserve order
%$hash = (z => 1, a => 2, y => 3, b => 4);
my $array = $yp->preserved_sequence([23, 24], style => YAML_FLOW_SEQUENCE_STYLE);
my $data = $yp->preserved_mapping({});
%$data = ( map => $hash, seq => $array );
my $dump = $yp->dump_string($data);
# output
---
map: {z: 1, a: 2, y: 3, b: 4}
seq: [23, 24]
=head2 loader
Returns or sets the loader object, by default L
=head2 dumper
Returns or sets the dumper object, by default L
=head2 schema
Returns or sets the schema object
=head2 default_schema

=head1 FUNCTIONS
The functions C, C, C and C are provided
as a drop-in replacement for other existing YAML processors.
No function is exported by default.
Note that in scalar context, C and C return the first
document (like L), while L and L return the
last.

=item Load
use YAML::PP qw/ Load /;

=item L
One of the three YAML 1.2 official schemas.
=item L
One of the three YAML 1.2 official schemas. Default

Serializing Perl objects and types
=item L
Serializing binary data
=item L
YAML 1.1 merge keys for mappings
=item L
Experimental.
It was accidentally added in 0.38.1, and unknown tags forbidden.
This was reverted in 0.39.0
By default they will result in an error.
=item L
Include other YAML files via C tags
=item L
Deprecated. See option C
=back
To make the parsing process faster, you can plugin the libyaml parser
with L.
=head1 IMPLEMENTATION
The process of loading and dumping is split into the following steps:
Load:
YAML Stream Tokens Event List Data Structure
---------> ---------> --------->
lex parse construct
Dump:
Data Structure Event List YAML Stream
---------> --------->
represent emit
You can dump basic perl types like hashes, arrays, scalars (strings, numbers).
For dumping blessed objects and things like coderefs have a look at
L/L.
=over
=item L
The Lexer is reading the YAML stream into tokens. This makes it possible
to generate syntax highlighted YAML output.
Note that the API to retrieve the tokens will change.
=item L
The Parser retrieves the tokens from the Lexer. The main YAML content is then
parsed with the Grammar.
=item L
=item L
The Constructor creates a data structure from the Parser events.
=item L
The Loader combines the constructor and parser.
=item L
The Dumper will delegate to the Representer
=item L
The Representer will create Emitter events from the given data structure.
=item L
The Emitter creates a YAML stream.

=head2 YAML::PP::Parser
Still TODO:
=over 4
=item Implicit collection keys
---
[ a, b, c ]: value
=item Implicit mapping in flow style sequences
This is supported since 0.029 (except some not relevant cases):
---
[ a, b, c: d ]
# equals
[ a, b, { c: d } ]
=item Plain mapping keys ending with colons
---
key ends with two colons::: value
This was implemented in 0.037.
=item Supported Characters
If you have valid YAML that's not parsed, or the other way round, please
create an issue.
=item Line and Column Numbers
You will see line and column numbers in the error message. The column numbers
might still be wrong in some cases.
=item Error Messages
The error messages need to be improved.
=item Unicode Surrogate Pairs
Currently loaded as single characters without validating
=item Possibly more
=back
=head2 YAML::PP::Constructor
The Constructor now supports all three YAML 1.2 Schemas, Failsafe, JSON and
Core. Additionally you can choose the schema for YAML 1.1 as C.
Too see what strings are resolved as booleans, numbers, null etc. look at
L.
You can choose the Schema like this:
my $ypp = YAML::PP->new(schema => ['JSON']); # default is 'Core'
The Tags C and C are still ignored for now.
It supports:
=over 4
=item Handling of Anchors/Aliases
Like in modules like L, the Constructor will use references for mappings and
sequences, but obviously not for scalars.
L uses real aliases, which allows also aliasing scalars. I might add
an option for that since aliasing is now available in pure perl.
=item Boolean Handling
You can choose between C<'perl'> (1/'', currently default), C<'JSON::PP'> and
C<'boolean'>.pm for handling boolean types. That allows you to dump the data
structure with one of the JSON modules without losing information about
booleans.
=item Numbers
Numbers are created as real numbers instead of strings, so that they are
dumped correctly by modules like L or L, for example.
=item Complex Keys
Mapping Keys in YAML can be more than just scalars. Of course, you can't load
that into a native perl structure. The Constructor will stringify those keys
with L instead of just returning something like
C.
Example:
use YAML::PP;
use JSON::PP;
my $ypp = YAML::PP->new;
my $coder = JSON::PP->new->ascii->pretty->allow_nonref->canonical;
my $yaml = <<'EOM';
complex:
?
?
a: 1
c: 2
: 23
: 42
EOM
my $data = $yppl->load_string($yaml);
say $coder->encode($data);
__END__
{
"complex" : {
"{'{a => 1,c => 2}' => 23}" : 42
}
}

TODO:

=item Parse Tree
I would like to generate a complete parse tree, that allows you to manipulate
the data structure and also dump it, including all whitespaces and comments.
The spec says that this is throwaway content, but I read that many people
wish to be able to keep the comments.
=back
=head2 YAML::PP::Dumper, YAML::PP::Emitter
The Dumper should be able to dump strings correctly, adding quotes
whenever a plain scalar would look like a special string, like C,
or when it contains or starts with characters that are not allowed.
Most strings will be dumped as plain scalars without quotes. If they
contain special characters or have a special meaning, they will be dumped
with single quotes. If they contain control characters, including <"\n">,
they will be dumped with double quotes.
It will recognize JSON::PP::Boolean and boolean.pm objects and dump them
correctly.
Numbers which also have a C flag will be recognized as numbers and not
as strings:
my $int = 23;
say "int: $int"; # $int will now also have a PV flag
That means that if you accidentally use a string in numeric context, it will
also be recognized as a number:
my $string = "23";
my $something = $string + 0;
print $yp->dump_string($string);
# will be emitted as an integer without quotes!
The layout is like libyaml output:
key:
- a
- b
- c
---
- key1: 1
key2: 2
key3: 3
---
- - a1
- a2
- - b1
- b2
=head1 FAQ - Frequently Asked Questions
=over
=item Are C<<<> merge keys supported?
Yes, this can be enabled optionally, see L
=item Is there a linter / formatter for YAML
There is the widely used L<"yamllint"|https://yamllint.readthedocs.io/>, based on
python's PyYAML. It is very configurable and will report errors or warnings.
It cannot format.
Now there is also L, which will format the given file according
to your configuration. So far only a few configuration options exist, but
they can already be quite helpful.
=back
=head1 Which YAML module should I use?
There are many YAML modules on CPAN. For historical reasons some of them
aren't handling YAML correctly.
Most of them are not compatible with the YAML spec and with each other, meaning
they can interpret the same YAML differently.
The behaviours we are discussing here can be divided into parsing issues
(syntax) and loading/constructing issues (for example type resolving which
decides what is a number, boolean or null).
See also L (parsing) and
L (loading).
=over
=item L<"YAML.pm"|YAML>
It was written even before the YAML 1.0 spec was finished and by that enabled
perl users to process YAML very early. It might work for you if you have simple
data, but it's missing quite some features and can also produce YAML that
doesn't roundtrip. Nowadays it might be a good idea to switch.
=item L
A libyaml binding that is robust and widely used. However, there are two
things to consider.
1. (syntax) libyaml diverged from the spec in several aspects. They are rare though.
2. The type resolving does not adhere to YAML 1.1 or YAML 1.2, meaning it is
incompatible with other YAML libraries in perl or other languages.
=item L
It implements both a tiny subset of YAML, but also a superset. Meaning
it will happily accept some YAML documents that are not officially valid.
Type resolving is also not implemented according to the spec.
