D:YAML is a YAML parser library for D. It is mostly compliant with the YAML 1.1 spec, although there are some unsupported features (e.g. recursive data structures). Currently there is only a parser, not an emitter. The API is not yet stable, there will be breaking changes. (e.g. part of the API depends on std.stream and will probably be changed when std.stream is rewritten.) Docs can be found in doc/html in the package. There are some (very) basic tutorials/examples and an API doc. Much of D:YAML code has been ported to D from PyYAML. D:YAML is written in D2. There is no D1 or Tango support, and none is planned.

Interesting, I've been looking for a D YAML library for a while. How is the performance, have you made any benchmarks? -- /Jacob Carlborg

Not yet. I intend to implement an emitter first and then start benchmarking/profiling/optimizing. However, as much of the code is directly translated from PyYAML (Python code, not the libYAML C extension), I imagine it will be somewhat faster than that.

Does the parser/lexer take advantage of D's slices to make it faster? -- /Jacob Carlborg

In some places, yes, in some places, no. I didn't concentrate on preventing new strings from being allocated, but a lot of string data should pass through the code unchanged, with just slices changing. Phobos functions should help with that (E.g: afaik when you split() a string, you just get slices to the same string data?). Still, the parser, scanner (and composer) are precisely the parts of code that were ported from PyYAML, and the code is mostly similar to PyYAML.

Ok, I see. It should be possible to create a parser that doesn't allocate memory, only uses slicing. A great example of that is the XML module in Tango. -- /Jacob Carlborg

Cool, I've been interested in YAML, but there wasn't a D library for it.

Very nice! Gotta have a look on this one.
