Yaml

Welcome to the BoxLang YAML Module

This module provides a YAML parser and emitter for BoxLang. It is based on the SnakeYAML library and provides a simple way to parse and emit YAML content in BoxLang.

# For Operating Systems using our Quick Installer.
install-bx-module bx-yaml

# Using CommandBox to install for web servers.
box install boxlang-yaml

Usage

This module registers the following BIFS:

• yamlSerialize( content, [filepath], [charset=utf8] ):yaml : Serialize a BoxLang variable into a YAML string. You can also serialize to a file if you provide a file path.

• yamlDeserialize( content ):any : Deserialize a YAML string into a BoxLang variable.

• yamlDeserializeFile( filepath, [charset=utf8] ):any : Deserialize a YAML file into a BoxLang variable.

Here is a simple example:

// Serialize a BoxLang structure into a YAML string
yaml = yamlSerialize( { name="Luis", age=21, city="Orlando" } );
// Serialize a more complex structure
yaml = yamlSerialize( { name="Luis", age=21, city="Orlando", address={ street="1234", city="Orlando", state="FL" } } );

// Deserialize a YAML string into a BoxLang structure
data = yamlDeserialize( yaml );

// Deserialize a YAML file into a BoxLang structure
data = yamlDeserializeFile( "data.yml" );

BoxLang Class Serialization

BoxLang classes will be serialized as a structure according to its properties. However it must adhere to the following rules:

• The class must have a serializable = true annotation. or none at all, that is the default.

• The property must have a serializable = true annotation or none at all, that is the default.

• The property must NOT exist in the yamlExclude list in the class or the parent class.

• The property must NOT have a yamlExclude annotation.

BoxLang Class Custom Serialization

If you are serializing BoxLang classes, you can implement the toYAML() method in your classes to provide a custom serialization. Here is an example:

class {

	function init( required name="", required age=0, required city="" ){
		variables.name = arguments.name;
		variables.age = arguments.age;
		variables.city = arguments.city;
		return this;
	}

	function toYAML(){
		return { name=variables.name, city=variables.city } );
	}

}
