Support for serialising Haskell to and from Yaml.
C Haskell C++


Provides support for parsing and emitting Yaml documents.

This package includes the full libyaml C library version 0.1.7 by Kirill Simonov in the package so you don't need to worry about any non-Haskell dependencies.

The package is broken down into two primary modules. Data.Yaml provides a high-level interface based around the JSON datatypes provided by the aeson package. Text.Libyaml provides a lower-level, streaming interface. For most users, Data.Yaml is recommended.


Usage examples can be found in the Data.Yaml documentation or in the examples directory.

Additional modules

  • Data.Yaml.Include supports adding !include directives to your YAML files.
  • Data.Yaml.Builder and Data.Yaml.Parser allow more fine-grained control of parsing an rendering, as opposed to just using the aeson typeclass and datatype system for parsing and rendering.
  • Data.Yaml.Aeson is currently a re-export of Data.Yaml to explicitly choose to use the aeson-compatible API.
