Dovetail

Dovetail is a general-purpose PureScript interpreter written in Haskell.

It has excellent support for interop with Haskell code via PureScript's foreign function interface, along with a high-level Haskell API for integrating such code.

As such, it is possible to write low-level or domain-specific code in Haskell, and then to write the "glue code" in PureScript. In this way, Dovetail is a tool for reusing the frontend of the PureScript compiler (its syntax and type checker) to build domain specific languages in Haskell.

Getting Started

To understand the library and how to use it, it is recommended that you read through the Haddock documentation, alongside the provided examples:

• Hackage documentation
  • dovetail on Hackage
  • dovetail-aeson on Hackage
  • Haddocks on GitHub Pages
• Examples:
  • JSON query language
  • Fake data generator

You can build the code and examples in this repository using stack build, and run the test suite with stack test.
