Learn basic concepts, key features, and capabilities of YAML.

In this course, you will run through a comprehensive overview of the YAML data serialization language and its syntax. You will also cover the basic concepts behind this language, understand its main features, and the capabilities of YAML. 

You will kick things off by understanding what exactly YAML is. You will then move on to more concrete topics like syntax, data types, and more complex data types such as sequences, mappings, and pairs.

By the end of this course, you will have a great new skill that is transferable and highly applicable.

Introduction to YAML

You would need a YAML Parser library to validate the structural correctness and extract information from text input. 

Emitter is a code generator that can convert the native data type of a language into YAML format. 

## Libraries for parsing and emitting YAML data

Below is a list of parsers and emitter libraries for YAML in various programming languages. 

| **Language** |  **Library**| **Description** | 
|---|---|:---| 
|  C| LibYAML |  A C library for parsing and emitting YAML|
| Python | PyYAML| YAML parser and emitter for Python | 
| Ruby | ruby/yaml| Provides a `Ruby` interface for data serialization in YAML format |
| Go | go-yaml| Enables Go programs to comfortably encode and decode YAML values.
| PHP | symfony/yaml| It parses YAML strings to convert them to PHP arrays.| 
| .NET | YamlDotNet | .NET library for YAML | 
| JavaScript | js-yaml | YAML parser for JavaScript |
| Java | SnakeYAML Engine|  A YAML 1.2 processor for the Java Virtual Machine version 8 and higher. There is a YAML 1.1 parser and emitter for Java
| Perl | YAML::PP| A Perl based modular YAML processor.|

## Links to useful YAML tools

Below are some useful tools you may find handy for creating or editing a `YAML` data file while using any of the above applications.

- [YAML Lint](http://www.yamllint.com/) - Validate and verify your documents by pasting your `YAML` on this page.
- [YAML Validator](https://codebeautify.org/yaml-validator) - Similar to the `YAML` lint tool, you can copy, paste, and validate your `YAML` data online with this URL.
- [YAML Beautifier](https://codebeautify.org/yaml-beautifier) - Online tool to convert unformatted or ugly `YAML` data into a well-formatted one for saving and sharing with others.
- [YAML Converter](https://codebeautify.org/yaml-to-json-xml-csv) - Convert your `YAML` data into `JSON`, `XML`, or `CSV` (comma separated values) format online. 
- [Online YAML Parser](http://yaml-online-parser.appspot.com/) - Just write some 'YAML' and it outputs corresponding `JSON` format in real time.
- [YAML to PDF Table Converter](https://www.beautifyconverter.com/yaml-to-pdf-converter.php) - Online tool to convert `YAML` to
`PDF table`.

You'll find the above list useful if you are looking to evaluate various programming languages for their `YAML` support for the purpose of building an application where consuming and exchanging data is done using `YAML` format.
