# agda2hs

Agda2hs is a tool for producing verified and readable Haskell code by extracting

it from a (lightly annotated) Agda program. The goal of this project is *not* to

translate arbitrary Agda code to Haskell. Rather it is to carve out a common

sublanguage between Agda and Haskell, with a straightforward translation from

the Agda side to the Haskell side. This lets you write your program in the Agda

fragment, using full Agda to prove properties about it, and then translate it to

nice looking readable Haskell code that you can show your Haskell colleagues

without shame.

## Documentation

Documentation can be viewed at https://agda.github.io/agda2hs. You can also find

examples in the `test` directory of this repository, in particular the file

[Test.agda](https://github.com/agda/agda2hs/blob/master/test/Test.agda). The

documentation is a work in progress, so if you have been using agda2hs and want

to contribute in some way, adding documentation or examples would be very

welcome.

agda2hs was introduced in the Haskell Symposium '22 paper [Reasonable Agda is

Correct Haskell: Writing Verified Haskell using

agda2hs](https://jesper.sikanda.be/files/reasonable-agda-is-correct-haskell.pdf).

## Future work

Currently agda2hs is under active development, please take a look at

the [issue tracker](https://github.com/agda/agda2hs/issues). If you

have a suggestion for a new feature that is not yet on the issue

tracker, you are welcome to create a new issue or a PR. Feature

requests should be of the form "Add support for Haskell feature X",

*not* "Add support for Agda feature Y" (see "Objective" above). If you

want to compile arbitrary Agda code to Haskell, you are advised to use

Agda's built-in GHC backend instead.
