YAML parser and emitter for the D programming language

branch: master
README.rst

D:YAML 0.4

Introduction

D:YAML is an open source YAML parser and emitter library for the D programming language. It is (almost) compliant to the YAML 1.1 specification. D:YAML is based on PyYAML created by Kirill Simonov. It has no external dependencies, it only needs a D compiler and Phobos (standard library). It is written in D2 and there are no plans for D1 support.

D:YAML is designed to be easy to use while supporting the full feature set of YAML. To start using it in your project, see the Getting Started tutorial.

D:YAML is still a work in progress. Its API is not stable and there might be compatibility breaking changes. For instance, currently some D:YAML API functions depend on the std.stream module in Phobos. This module is expected to be rewritten in future and D:YAML will change accordingly.

Features

  • Easy to use, high level API and detailed debugging messages.
  • Detailed API documentation and tutorials.
  • Code examples.
  • No external dependencies.
  • Supports all YAML 1.1 constructs. All examples from the YAML 1.1 specification are parsed correctly.
  • Reads from and writes to YAML files as well as memory or user defined streams.
  • UTF-8, UTF-16 and UTF-32 encodings are supported, both big and little endian (plain ASCII also works as it is a subset of UTF-8).
  • Support for both block (Python-like, based on indentation) and flow (JSON-like, based on bracing) constructs.
  • Support for YAML anchors and aliases.
  • Support for default values in mappings.
  • Support for custom tags (data types), and implicit tag resolution for custom scalar tags.
  • All tags (data types) described at http://yaml.org/type/ are supported, with the exception of tag:yaml.org,2002:yaml, which is used to represent YAML code in YAML.
  • Remembers YAML style information between loading and dumping if possible.
  • There is no support for recursive data structures. There are no plans to implement this at the moment.
