- You probably think YAML stands for "Yet Another Markup Language". It
- ain't! YAML is really a data serialization language. But if you want
- to think of it as a markup, that's OK with me. A lot of people try
- to use XML as a serialization format.
-
- "YAML" is catchy and fun to say. Try it. "YAML, YAML, YAML!!!"

-
- # Dump the Perl data structures back into YAML.
- print Dump($string, $arrayref, $hashref);

-
-=head1 DESCRIPTION
-
-The YAML.pm module implements a YAML Loader and Dumper based on the YAML
-1.0 specification. L<http://www.yaml.org/spec/>
-
-YAML is a generic data serialization language that is optimized for
-human readability. It can be used to express the data structures of most
-modern programming languages. (Including Perl!!!)
-
-For information on the YAML syntax, please refer to the YAML
-specification.
-
-=head1 WHY YAML IS COOL
-
-=over 4
-
-=item YAML is readable for people.
-
-It makes clear sense out of complex data structures. You should find
-that YAML is an exceptional data dumping tool. Structure is shown
-through indentation, YAML supports recursive data, and hash keys are
-sorted by default. In addition, YAML supports several styles of scalar
-formatting for different types of data.
-
-=item YAML is editable.
-
-YAML was designed from the ground up to be an excellent syntax for
-configuration files. Almost all programs need configuration files, so
-why invent a new syntax for each one? And why subject users to the
-complexities of XML or native Perl code?
-
-=item YAML is multilingual.
-
-Yes, YAML supports Unicode. But I'm actually referring to programming
-languages. YAML was designed to meet the serialization needs of Perl,
-Python, Ruby, Tcl, PHP, Javascript and Java. It was also designed to be
-interoperable between those languages. That means YAML serializations
-produced by Perl can be processed by Python.
-
-=item YAML is taint safe.
-
-Using modules like Data::Dumper for serialization is fine as long as you
-can be sure that nobody can tamper with your data files or
-transmissions. That's because you need to use Perl's C<eval()> built-in
-to deserialize the data. Somebody could add a snippet of Perl to erase
-your files.
-
-YAML's parser does not need to eval anything.
-
-=item YAML is full featured.
-
-YAML can accurately serialize all of the common Perl data structures and
-deserialize them again without losing data relationships. Although it is
-not 100% perfect (no serializer is or can be perfect), it fares as well
-as the popular current modules: Data::Dumper, Storable, XML::Dumper and
-Data::Denter.
-
-YAML.pm also has the ability to handle code (subroutine) references and
-typeglobs. (Still experimental) These features are not found in Perl's
-other serialization modules.
-
-=item YAML is extensible.
-
-The YAML language has been designed to be flexible enough to solve it's
-own problems. The markup itself has 3 basic construct which resemble
-Perl's hash, array and scalar. By default, these map to their Perl
-equivalents. But each YAML node also supports a tagging mechanism (type
-system) which can cause that node to be interpreted in a completely
-different manner. That's how YAML can support object serialization and
-oddball structures like Perl's typeglob.
-
-=back
-
-=head1 YAML IMPLEMENTATIONS IN PERL
-
-This module, YAML.pm, is really just the interface module for YAML
-modules written in Perl. The basic interface for YAML consists of two
-functions: C<Dump> and C<Load>. The real work is done by the modules
-YAML::Dumper and YAML::Loader.
-
-Different YAML module distributions can be created by subclassing
-YAML.pm and YAML::Loader and YAML::Dumper. For example, YAML-Simple
-consists of YAML::Simple YAML::Dumper::Simple and YAML::Loader::Simple.
-
-Why would there be more than one implementation of YAML? Well, despite
-YAML's offering of being a simple data format, YAML is actually very
-deep and complex. Implementing the entirety of the YAML specification is
-a daunting task.
-
-For this reason I am currently working on 3 different YAML implementations.
-
-=over
-
-=item YAML
-
-The main YAML distribution will keeping evolving to support the entire
-YAML specification in pure Perl. This may not be the fastest or most
-stable module though. Currently, YAML.pm has lots of known bugs. It is
-mostly a great tool for dumping Perl data structures to a readable form.
-
-=item YAML::Lite
-
-The point of YAML::Lite is to strip YAML down to the 90% that people
-use most and offer that in a small, fast, stable, pure Perl form.
-YAML::Lite will simply die when it is asked to do something it can't.
-
-=item YAML::Syck
-
-C<libsyck> is the C based YAML processing library used by the Ruby
-programming language (and also Python, PHP and Pugs). YAML::Syck is the
-Perl binding to C<libsyck>. It should be very fast, but may have
-problems of its own. It will also require C compilation.
-
-NOTE: Audrey Tang has actually completed this module and it works great
- and is 10 times faster than YAML.pm.
-
-=back
-
-In the future, there will likely be even more YAML modules. Remember,
-people other than Ingy are allowed to write YAML modules!
-
-=head1 FUNCTIONAL USAGE
-
-YAML is completely OO under the hood. Still it exports a few useful top
-level functions so that it is dead simple to use. These functions just
-do the OO stuff for you. If you want direct access to the OO API see the
-documentation for YAML::Dumper and YAML::Loader.
-
-=head2 Exported Functions
-
-The following functions are exported by YAML.pm by default. The reason
-they are exported is so that YAML works much like Data::Dumper. If you
-don't want functions to be imported, just use YAML with an empty
-import list:
-
- use YAML ();
-
-=over 4
-
-=item Dump(list-of-Perl-data-structures)
-
-Turn Perl data into YAML. This function works very much like
-Data::Dumper::Dumper(). It takes a list of Perl data strucures and
-dumps them into a serialized form. It returns a string containing the
-YAML stream. The structures can be references or plain scalars.
-
-=item Load(string-containing-a-YAML-stream)
-
-Turn YAML into Perl data. This is the opposite of Dump. Just like
-Storable's thaw() function or the eval() function in relation to
-Data::Dumper. It parses a string containing a valid YAML stream into a
-list of Perl data structures.
-
-=back
-
-=head2 Exportable Functions
-
-These functions are not exported by default but you can request them in
-an import list like this:
-
- use YAML qw'freeze thaw Bless';
-
-=over 4
-
-=item freeze() and thaw()
-
-Aliases to Dump() and Load() for Storable fans. This will also allow
-YAML.pm to be plugged directly into modules like POE.pm, that use the
-freeze/thaw API for internal serialization.
-
-=item DumpFile(filepath, list)
-
-Writes the YAML stream to a file instead of just returning a string.
-
-=item LoadFile(filepath)
-
-Reads the YAML stream from a file instead of a string.
-
-=item Bless(perl-node, [yaml-node | class-name])
-
-Associate a normal Perl node, with a yaml node. A yaml node is an object
-tied to the YAML::Node class. The second argument is either a yaml node
-that you've already created or a class (package) name that supports a
-yaml_dump() function. A yaml_dump() function should take a perl node and
-return a yaml node. If no second argument is provided, Bless will create
-a yaml node. This node is not returned, but can be retrieved with the
-Blessed() function.
-
-Here's an example of how to use Bless. Say you have a hash containing
-three keys, but you only want to dump two of them. Furthermore the keys
-must be dumped in a certain order. Here's how you do that:
-
- use YAML qw(Dump Bless);
- $hash = {apple => 'good', banana => 'bad', cauliflower => 'ugly'};
- print Dump $hash;
- Bless($hash)->keys(['banana', 'apple']);
- print Dump $hash;
-
-produces:
-
- ---
- apple: good
- banana: bad
- cauliflower: ugly
- ---
- banana: bad
- apple: good
-
-Bless returns the tied part of a yaml-node, so that you can call the
-YAML::Node methods. This is the same thing that YAML::Node::ynode()
-returns. So another way to do the above example is:
-
- use YAML qw(Dump Bless);
- use YAML::Node;
- $hash = {apple => 'good', banana => 'bad', cauliflower => 'ugly'};
- print Dump $hash;
- Bless($hash);
- $ynode = ynode(Blessed($hash));
- $ynode->keys(['banana', 'apple']);
- print Dump $hash;
-
-Note that Blessing a Perl data structure does not change it anyway. The
-extra information is stored separately and looked up by the Blessed
-node's memory address.
-
-=item Blessed(perl-node)
-
-Returns the yaml node that a particular perl node is associated with
-(see above). Returns undef if the node is not (YAML) Blessed.
-
-=back
-
-=head1 GLOBAL OPTIONS
-
-YAML options are set using a group of global variables in the YAML
-namespace. This is similar to how Data::Dumper works.
-
-For example, to change the indentation width, do something like:
-
- local $YAML::Indent = 3;
-
-The current options are:
-
-=over 4
-
-=item DumperClass
-
-You can override which module/class YAML uses for Dumping data.
-
-=item LoaderClass
-
-You can override which module/class YAML uses for Loading data.
-
-=item Indent
-
-This is the number of space characters to use for each indentation level
-when doing a Dump(). The default is 2.
-
-By the way, YAML can use any number of characters for indentation at any
-level. So if you are editing YAML by hand feel free to do it anyway that
-looks pleasing to you; just be consistent for a given level.
-
-=item SortKeys
-
-Default is 1. (true)
-
-Tells YAML.pm whether or not to sort hash keys when storing a document.
-
-YAML::Node objects can have their own sort order, which is usually what
-you want. To override the YAML::Node order and sort the keys anyway, set
-SortKeys to 2.
-
-=item Stringify
-
-Default is 0. (false)
-
-Objects with string overloading should honor the overloading and dump the
-stringification of themselves, rather than the actual object's guts.
-
-=item UseHeader
-
-Default is 1. (true)
-
-This tells YAML.pm whether to use a separator string for a Dump
-operation. This only applies to the first document in a stream.
-Subsequent documents must have a YAML header by definition.
-
-=item UseVersion
-
-Default is 0. (false)
-
-Tells YAML.pm whether to include the YAML version on the
-separator/header.
-
- --- %YAML:1.0
-
-=item AnchorPrefix
-
-Default is ''.
-
-Anchor names are normally numeric. YAML.pm simply starts with '1' and
-increases by one for each new anchor. This option allows you to specify a
-string to be prepended to each anchor number.
-
-=item UseCode
-
-Setting the UseCode option is a shortcut to set both the DumpCode and
-LoadCode options at once. Setting UseCode to '1' tells YAML.pm to dump
-Perl code references as Perl (using B::Deparse) and to load them back
-into memory using eval(). The reason this has to be an option is that
-using eval() to parse untrusted code is, well, untrustworthy.
-
-=item DumpCode
-
-Determines if and how YAML.pm should serialize Perl code references. By
-default YAML.pm will dump code references as dummy placeholders (much
-like Data::Dumper). If DumpCode is set to '1' or 'deparse', code
-references will be dumped as actual Perl code.
-
-DumpCode can also be set to a subroutine reference so that you can
-write your own serializing routine. YAML.pm passes you the code ref. You
-pass back the serialization (as a string) and a format indicator. The
-format indicator is a simple string like: 'deparse' or 'bytecode'.
-
-=item LoadCode
-
-LoadCode is the opposite of DumpCode. It tells YAML if and how to
-deserialize code references. When set to '1' or 'deparse' it will use
-C<eval()>. Since this is potentially risky, only use this option if you
-know where your YAML has been.
-
-LoadCode can also be set to a subroutine reference so that you can write
-your own deserializing routine. YAML.pm passes the serialization (as a
-string) and a format indicator. You pass back the code reference.
-
-=item UseBlock
-
-YAML.pm uses heuristics to guess which scalar style is best for a given
-node. Sometimes you'll want all multiline scalars to use the 'block'
-style. If so, set this option to 1.
-
-NOTE: YAML's block style is akin to Perl's here-document.
-
-=item UseFold
-
-If you want to force YAML to use the 'folded' style for all multiline
-scalars, then set $UseFold to 1.
-
-NOTE: YAML's folded style is akin to the way HTML folds text,
- except smarter.
-
-=item UseAliases
-
-YAML has an alias mechanism such that any given structure in memory gets
-serialized once. Any other references to that structure are serialized
-only as alias markers. This is how YAML can serialize duplicate and
-recursive structures.
-
-Sometimes, when you KNOW that your data is nonrecursive in nature, you
-may want to serialize such that every node is expressed in full. (ie as
-a copy of the original). Setting $YAML::UseAliases to 0 will allow you
-to do this. This also may result in faster processing because the lookup
-overhead is by bypassed.
-
-THIS OPTION CAN BE DANGEROUS. *If* your data is recursive, this option
-*will* cause Dump() to run in an endless loop, chewing up your computers
-memory. You have been warned.
-
-=item CompressSeries
-
-Default is 1.
-
-Compresses the formatting of arrays of hashes:
-
- -
- foo: bar
- -
- bar: foo
-
-becomes:
-
- - foo: bar
- - bar: foo
-
-Since this output is usually more desirable, this option is turned on by
-default.
-
-=back
-
-=head1 YAML TERMINOLOGY
-
-YAML is a full featured data serialization language, and thus has its
-own terminology.
-
-It is important to remember that although YAML is heavily influenced by
-Perl and Python, it is a language in its own right, not merely just a
-representation of Perl structures.
-
-YAML has three constructs that are conspicuously similar to Perl's hash,
-array, and scalar. They are called mapping, sequence, and string
-respectively. By default, they do what you would expect. But each
-instance may have an explicit or implicit tag (type) that makes it
-behave differently. In this manner, YAML can be extended to represent
-Perl's Glob or Python's tuple, or Ruby's Bigint.
-
-=over 4
-
-=item stream
-
-A YAML stream is the full sequence of unicode characters that a YAML
-parser would read or a YAML emitter would write. A stream may contain
-one or more YAML documents separated by YAML headers.
-
- ---
- a: mapping
- foo: bar
- ---
- - a
- - sequence
-
-=item document
-
-A YAML document is an independent data structure representation within a
-stream. It is a top level node. Each document in a YAML stream must
-begin with a YAML header line. Actually the header is optional on the
-first document.
-
- ---
- This: top level mapping
- is:
- - a
- - YAML
- - document
-
-=item header
-
-A YAML header is a line that begins a YAML document. It consists of
-three dashes, possibly followed by more info. Another purpose of the
-header line is that it serves as a place to put top level tag and anchor
-information.
-
- --- !recursive-sequence &001
- - * 001
- - * 001
-
-=item node
-
-A YAML node is the representation of a particular data stucture. Nodes
-may contain other nodes. (In Perl terms, nodes are like scalars.
-Strings, arrayrefs and hashrefs. But this refers to the serialized
-format, not the in-memory structure.)
-
-=item tag
-
-This is similar to a type. It indicates how a particular YAML node
-serialization should be transferred into or out of memory. For instance
-a Foo::Bar object would use the tag 'perl/Foo::Bar':
-
- - !perl/Foo::Bar
- foo: 42
- bar: stool
-
-=item collection
-
-A collection is the generic term for a YAML data grouping. YAML has two
-types of collections: mappings and sequences. (Similar to hashes and arrays)
-
-=item mapping
-
-A mapping is a YAML collection defined by unordered key/value pairs with
-unique keys. By default YAML mappings are loaded into Perl hashes.
-
- a mapping:
- foo: bar
- two: times two is 4
-
-=item sequence
-
-A sequence is a YAML collection defined by an ordered list of elements. By
-default YAML sequences are loaded into Perl arrays.
-
- a sequence:
- - one bourbon
- - one scotch
- - one beer
-
-=item scalar
-
-A scalar is a YAML node that is a single value. By default YAML scalars
-are loaded into Perl scalars.
-
- a scalar key: a scalar value
-
-YAML has many styles for representing scalars. This is important because
-varying data will have varying formatting requirements to retain the
-optimum human readability.
-
-=item plain scalar
-
-A plain sclar is unquoted. All plain scalars are automatic candidates
-for "implicit tagging". This means that their tag may be determined
-automatically by examination. The typical uses for this are plain alpha
-strings, integers, real numbers, dates, times and currency.
-
- - a plain string
- - -42
- - 3.1415
- - 12:34
- - 123 this is an error
-
-=item single quoted scalar
-
-This is similar to Perl's use of single quotes. It means no escaping
-except for single quotes which are escaped by using two adjacent
-single quotes.
-
- - 'When I say ''\n'' I mean "backslash en"'
-
-=item double quoted scalar
-
-This is similar to Perl's use of double quotes. Character escaping can
-be used.
-
- - "This scalar\nhas two lines, and a bell -->\a"
-
-=item folded scalar
-
-This is a multiline scalar which begins on the next line. It is
-indicated by a single right angle bracket. It is unescaped like the
-single quoted scalar. Line folding is also performed.
-
- - >
- This is a multiline scalar which begins on
- the next line. It is indicated by a single
- carat. It is unescaped like the single
- quoted scalar. Line folding is also
- performed.
-
-=item block scalar
-
-This final multiline form is akin to Perl's here-document except that
-(as in all YAML data) scope is indicated by indentation. Therefore, no
-ending marker is required. The data is verbatim. No line folding.

-
-=item parser
-
-A YAML processor has four stages: parse, load, dump, emit.
-
-A parser parses a YAML stream. YAML.pm's Load() function contains a
-parser.
-
-=item loader
-
-The other half of the Load() function is a loader. This takes the
-information from the parser and loads it into a Perl data structure.
-
-=item dumper
-
-The Dump() function consists of a dumper and an emitter. The dumper
-walks through each Perl data structure and gives info to the emitter.
-
-=item emitter
-
-The emitter takes info from the dumper and turns it into a YAML stream.
-
-NOTE:
-In YAML.pm the parser/loader and the dumper/emitter code are currently
-very closely tied together. In the future they may be broken into
-separate stages.
-
-=back
-
-For more information please refer to the immensely helpful YAML
-specification available at L<http://www.yaml.org/spec/>.
-
-=head1 ysh - The YAML Shell
-
-The YAML distribution ships with a script called 'ysh', the YAML shell.
-ysh provides a simple, interactive way to play with YAML. If you type in
-Perl code, it displays the result in YAML. If you type in YAML it turns
-it into Perl code.
-
-To run ysh, (assuming you installed it along with YAML.pm) simply type:
-
- ysh [options]
-
-Please read the C<ysh> documentation for the full details. There are
-lots of options.
-
-=head1 BUGS & DEFICIENCIES
-
-If you find a bug in YAML, please try to recreate it in the YAML Shell
-with logging turned on ('ysh -L'). When you have successfully reproduced
-the bug, please mail the LOG file to the author (ingy@cpan.org).
-
-WARNING: This is still *ALPHA* code. Well, most of this code has been
-around for years...
-
-BIGGER WARNING: YAML.pm has been slow in the making, but I am committed
-to having top notch YAML tools in the Perl world. The YAML team is close
-to finalizing the YAML 1.1 spec. This version of YAML.pm is based off of
-a very old pre 1.0 spec. In actuality there isn't a ton of difference,
-and this YAML.pm is still fairly useful. Things will get much better in
-the future.

-
-YAML::Node - A generic data node that encapsulates YAML information
-
-=head1 SYNOPSIS
-
- use YAML;
- use YAML::Node;
-
- my $ynode = YAML::Node->new({}, 'ingerson.com/fruit');
- %$ynode = qw(orange orange apple red grape green);
- print Dump $ynode;
-
-yields:
-
- --- !ingerson.com/fruit
- orange: orange
- apple: red
- grape: green
-
-=head1 DESCRIPTION
-
-A generic node in YAML is similar to a plain hash, array, or scalar node
-in Perl except that it must also keep track of its type. The type is a
-URI called the YAML type tag.
-
-YAML::Node is a class for generating and manipulating these containers.
-A YAML node (or ynode) is a tied hash, array or scalar. In most ways it
-behaves just like the plain thing. But you can assign and retrieve and
-YAML type tag URI to it. For the hash flavor, you can also assign the
-order that the keys will be retrieved in. By default a ynode will offer
-its keys in the same order that they were assigned.
-
-YAML::Node has a class method call new() that will return a ynode. You
-pass it a regular node and an optional type tag. After that you can
-use it like a normal Perl node, but when you YAML::Dump it, the magical
-properties will be honored.
-
-This is how you can control the sort order of hash keys during a YAML
-serialization. By default, YAML sorts keys alphabetically. But notice
-in the above example that the keys were Dumped in the same order they
-were assigned.
-
-YAML::Node exports a function called ynode(). This function returns the tied object so that you can call special methods on it like ->keys().
-
-keys() works like this:
-
- use YAML;
- use YAML::Node;
-
- %$node = qw(orange orange apple red grape green);
- $ynode = YAML::Node->new($node);
- ynode($ynode)->keys(['grape', 'apple']);
- print Dump $ynode;
-
-produces:
-
- ---
- grape: green
- apple: red
-
-It tells the ynode which keys and what order to use.
-
-ynodes will play a very important role in how programs use YAML. They
-are the foundation of how a Perl class can marshall the Loading and
-Dumping of its objects.
-
-The upcoming versions of YAML.pm will have much more information on this.
