DartLang.PubSpec

A library to serialize and deserialize Dart pubspec.yaml files.

Usage

var yaml = File.ReadAllText("pubspec.yaml");
var pubspec = PubSpecYamlSerializer.Deserialize(yaml);

Console.WriteLine($"Name: {pubspec.Name}");
Console.WriteLine($"Version: {pubspec.Version}");

You can also use the JSON serializer:

var json = File.ReadAllText("pubspec.json");
var pubspec = PubSpecJsonSerializer.Deserialize(json);

Custom Deserializer

YAML

You can also build your own deserializer using YamlDotNet directly:

var deserializer = new DeserializerBuilder()
    .IgnoreUnmatchedProperties()                                // pub.dev will ignore other properties
    .WithNamingConvention(UnderscoredNamingConvention.Instance) // dart uses underscores for properties
    .WithPubSpecConverters()                                    // converters for custom types
    .Build();

return deserializer.Deserialize<PubSpec>(reader);

JSON

In case you need to use custom JsonSerializerOptions, you can reuse the converters from DartLang.PubSpec.Serialization.Json:

var json = File.ReadAllText("pubspec.json");
var options = new JsonSerializerOptions
{
    PropertyNameCaseInsensitive = true,
    PropertyNamingPolicy = JsonNamingPolicy.CamelCase,
    Converters =
    {
        new SemVersionJsonConverter(),
        new SemVersionRangeJsonConverter(),
        new DependencyMapJsonConverter(),
        new PlatformsJsonConverter(),
    },
};

return JsonSerializer.Deserialize<PubSpec>(json, options);

Serialization

Serialization is currently not supported, but should not be hard to implement yourself.
