By contrast, our General Public +License is intended to guarantee your freedom to share and change free +software--to make sure the software is free for all its users. The +General Public License applies to the Free Software Foundation's +software and to any other program whose authors commit to using it. +You can use it for your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Specifically, the General Public License is designed to make +sure that you have the freedom to give away or sell copies of free +software, that you receive source code or can get it if you want it, +that you can change the software or use pieces of it in new free +programs; and that you know you can do these things. + + To protect your rights, we need to make restrictions that forbid +anyone to deny you these rights or to ask you to surrender the rights. +These restrictions translate to certain responsibilities for you if you +distribute copies of the software, or if you modify it. + + For example, if you distribute copies of a such a program, whether +gratis or for a fee, you must give the recipients all the rights that +you have. You must make sure that they, too, receive or can get the +source code. And you must tell them their rights. + + We protect your rights with two steps: (1) copyright the software, and +(2) offer you this license which gives you legal permission to copy, +distribute and/or modify the software. + + Also, for each author's protection and ours, we want to make certain +that everyone understands that there is no warranty for this free +software. If the software is modified by someone else and passed on, we +want its recipients to know that what they have is not the original, so +that any problems introduced by others will not reflect on the original +authors' reputations. + + The precise terms and conditions for copying, distribution and +modification follow. + + GNU GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License Agreement applies to any program or other work which +contains a notice placed by the copyright holder saying it may be +distributed under the terms of this General Public License. The +"Program", below, refers to any such program or work, and a "work based +on the Program" means either the Program or any work containing the +Program or a portion of it, either verbatim or with modifications. Each +licensee is addressed as "you". + + 1. You may copy and distribute verbatim copies of the Program's source +code as you receive it, in any medium, provided that you conspicuously and +appropriately publish on each copy an appropriate copyright notice and +disclaimer of warranty; keep intact all the notices that refer to this +General Public License and to the absence of any warranty; and give any +other recipients of the Program a copy of this General Public License +along with the Program. You may charge a fee for the physical act of +transferring a copy. + + 2. You may modify your copy or copies of the Program or any portion of +it, and copy and distribute such modifications under the terms of Paragraph +1 above, provided that you also do the following: + + a) cause the modified files to carry prominent notices stating that + you changed the files and the date of any change; and + + b) cause the whole of any work that you distribute or publish, that + in whole or in part contains the Program or any part thereof, either + with or without modifications, to be licensed at no charge to all + third parties under the terms of this General Public License (except + that you may choose to grant warranty protection to some or all + third parties, at your option). + + c) If the modified program normally reads commands interactively when + run, you must cause it, when started running for such interactive use + in the simplest and most usual way, to print or display an + announcement including an appropriate copyright notice and a notice + that there is no warranty (or else, saying that you provide a + warranty) and that users may redistribute the program under these + conditions, and telling the user how to view a copy of this General + Public License. + + d) You may charge a fee for the physical act of transferring a + copy, and you may at your option offer warranty protection in + exchange for a fee. + +Mere aggregation of another independent work with the Program (or its +derivative) on a volume of a storage or distribution medium does not bring +the other work under the scope of these terms. + + 3. You may copy and distribute the Program (or a portion or derivative of +it, under Paragraph 2) in object code or executable form under the terms of +Paragraphs 1 and 2 above provided that you also do one of the following: + + a) accompany it with the complete corresponding machine-readable + source code, which must be distributed under the terms of + Paragraphs 1 and 2 above; or, + + b) accompany it with a written offer, valid for at least three + years, to give any third party free (except for a nominal charge + for the cost of distribution) a complete machine-readable copy of the + corresponding source code, to be distributed under the terms of + Paragraphs 1 and 2 above; or, + + c) accompany it with the information you received as to where the + corresponding source code may be obtained. (This alternative is + allowed only for noncommercial distribution and only if you + received the program in object code or executable form alone.) + +Source code for a work means the preferred form of the work for making +modifications to it. For an executable file, complete source code means +all the source code for all modules it contains; but, as a special +exception, it need not include source code for modules which are standard +libraries that accompany the operating system on which the executable +file runs, or for standard header files or definitions files that +accompany that operating system. + + 4. You may not copy, modify, sublicense, distribute or transfer the +Program except as expressly provided under this General Public License. +Any attempt otherwise to copy, modify, sublicense, distribute or transfer +the Program is void, and will automatically terminate your rights to use +the Program under this License. However, parties who have received +copies, or rights to use copies, from you under this General Public +License will not have their licenses terminated so long as such parties +remain in full compliance. + + 5. By copying, distributing or modifying the Program (or any work based +on the Program) you indicate your acceptance of this license to do so, +and all its terms and conditions. + + 6. Each time you redistribute the Program (or any work based on the +Program), the recipient automatically receives a license from the original +licensor to copy, distribute or modify the Program subject to these +terms and conditions. You may not impose any further restrictions on the +recipients' exercise of the rights granted herein. + + 7. The Free Software Foundation may publish revised and/or new versions +of the General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + +Each version is given a distinguishing version number. If the Program +specifies a version number of the license which applies to it and "any +later version", you have the option of following the terms and conditions +either of that version or of any later version published by the Free +Software Foundation. If the Program does not specify a version number of +the license, you may choose any version ever published by the Free Software +Foundation. + + 8. If you wish to incorporate parts of the Program into other free +programs whose distribution conditions are different, write to the author +to ask for permission. For software which is copyrighted by the Free +Software Foundation, write to the Free Software Foundation; we sometimes +make exceptions for this. Our decision will be guided by the two goals +of preserving the free status of all derivatives of our free software and +of promoting the sharing and reuse of software generally. + + NO WARRANTY + + 9. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY +FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN +OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES +PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED +OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF +MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS +TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE +PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, +REPAIR OR CORRECTION. + + 10. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR +REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, +INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING +OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED +TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY +YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER +PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE +POSSIBILITY OF SUCH DAMAGES. + + END OF TERMS AND CONDITIONS + + Appendix: How to Apply These Terms to Your New Programs + + If you develop a new program, and you want it to be of the greatest +possible use to humanity, the best way to achieve this is to make it +free software which everyone can redistribute and change under these +terms. + + To do so, attach the following notices to the program. It is safest to +attach them to the start of each source file to most effectively convey +the exclusion of warranty; and each file should have at least the +"copyright" line and a pointer to where the full notice is found. + + <one line to give the program's name and a brief idea of what it does.> + Copyright (C) 19yy <name of author> + + This program is free software; you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation; either version 1, or (at your option) + any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the + GNU General Public License for more details. + + You should have received a copy of the GNU General Public License + along with this program; if not, write to the Free Software + Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston MA 02110-1301 USA + + +Also add information on how to contact you by electronic and paper mail. + +If the program is interactive, make it output a short notice like this +when it starts in an interactive mode: + + Gnomovision version 69, Copyright (C) 19xx name of author + Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. + This is free software, and you are welcome to redistribute it + under certain conditions; type `show c' for details. + +The hypothetical commands `show w' and `show c' should show the +appropriate parts of the General Public License.

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. + +WHY YAML IS COOL + + 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. + + 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? + + 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. + + 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 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. + + 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. + + 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. + +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: Dump and 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. + + 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. + + YAML::Tiny + + The point of YAML::Tiny is to strip YAML down to the 90% that people + use most and offer that in a small, fast, stable, pure Perl form. + YAML::Tiny will simply die when it is asked to do something it can't. + + YAML::Syck + + 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 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. + + In the future, there will likely be even more YAML modules. Remember, + people other than Ingy are allowed to write YAML modules! + +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. + + 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 (); + + 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 structures and + dumps them into a serialized form. It returns a string containing the + YAML stream. The structures can be references or plain scalars. + + 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. + + 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'; + + 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. + + DumpFile(filepath, list) + + Writes the YAML stream to a file instead of just returning a string. + + LoadFile(filepath) + + Reads the YAML stream from a file instead of a string. + + 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. + + 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. + +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: + + DumperClass + + You can override which module/class YAML uses for Dumping data. + + LoaderClass + + You can override which module/class YAML uses for Loading data. + + 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. + + 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. + + 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. + + 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. + + UseVersion + + Default is 0. (false) + + Tells YAML.pm whether to include the YAML version on the + separator/header. + + --- %YAML:1.0 + + 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. + + 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. + + 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'. + + 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 + 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. + + 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. + + 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. + + 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. + + 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. + + QuoteNumericStrings + + Default is 0. (false) + + Adds detection mechanisms to encode strings that resemble numbers + with mandatory quoting. + + This ensures leading that things like leading/trailing zeros and + other formatting are preserved. + +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. + + 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 + + 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 + + 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 + + node + + A YAML node is the representation of a particular data structure. + 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.) + + 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 + + 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) + + 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 + + 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 + + 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. + + plain scalar + + A plain scalar 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 + + 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"' + + 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" + + 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. + + 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.

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 + +=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 L<YAML::Dumper> and +L<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::Tiny + +The point of YAML::Tiny is to strip YAML down to the 90% that people use most +and offer that in a small, fast, stable, pure Perl form. YAML::Tiny 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 + +=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 structures 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 + +=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 C<yaml_dump()> +function. A C<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 + +=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. B<If> your data is recursive, this option +B<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. + +=item QuoteNumericStrings + +Default is 0. (false) + +Adds detection mechanisms to encode strings that resemble numbers with +mandatory quoting. + +This ensures leading that things like leading/trailing zeros and other +formatting are preserved. + +=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 + +=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 structure. 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 scalar 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. + + - | + QTY DESC PRICE TOTAL + --- ---- ----- ----- + 1 Foo Fighters $19.95 $19.95 + 2 Bar Belles $29.95 $59.90 + +=item parser + +A YAML processor has four stages: parse, load, dump, emit. + +A parser parses a YAML stream.

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. + +=head1 AUTHOR + +Ingy döt Net <ingy@cpan.org> + +=head1 COPYRIGHT + +Copyright 2001-2014.
