fhir_yaml 0.9.0

Dart package to format JSON data to YAML. Supports formatting conventions of pubspec files.

toYaml

This is just my personal branch of the json2yaml package by Alexei Sintotski. However, in order to be able to include it in some of my other packages, it needs to be published. I have added some additional formatting because some of the json that I needed to transform included complicated html/xml tags, plus I wanted to try and remove any extra lines that weren't necessary.

json2yaml()

json2yaml is the function to format JSON data to YAML.

  const developerData = {
    'name': "Martin D'vloper",
    'job': 'Developer',
    'skill': 'Elite',
    'employed': true,
    'foods': ['Apple', 'Orange', 'Strawberry', 'Mango'],
    'languages': {
      'perl': 'Elite',
      'python': 'Elite',
      'pascal': 'Lame',
    },
    'education': '4 GCSEs\n3 A-Levels\nBSc in the Internet of Things'
  };

  print(json2yaml(developerData));

This function is implemented in a very basic and perhaps naive way, please let me know if it does not work for you.

Usage

To use fhir_yaml, add the following dependency to pubspec.yaml:

dependencies:
  fhir_yaml: ^0.2.1

Advanced usage: YAML formatting styles

json2yaml supports the optional argument to customize YAML formatting for various use cases. At the moment, it supports the three following formatting styles:

• YamlStyle.generic (default) -- Default formatting style applicable in most cases
• YamlStyle.pubspecYaml -- YAML formatting style following pubspec.yaml formatting conventions
• YamlStyle.pubspecLock -- YAML formatting style following pubspec.lock formatting conventions

YAML style is supplied as an optional argument to json2yaml():

/// Yaml formatting control options
enum YamlStyle {
  generic,
  pubspecYaml,
  pubspecLock,
}

/// Converts JSON to YAML representation
String json2yaml(
  Map<String, dynamic> json, {
  YamlStyle yamlStyle = YamlStyle.generic,
});
