You will probably want to read the language-agnostic README here:

• dhall-lang README

This repository focuses on the Haskell bindings to Dhall and contains the following packages:

• dhall -
• dhall-bash -
• dhall-json -
• dhall-text -

Navigate to each package's directory for their respective READMEs

You can download pre-built binaries for Windows and Linux on the release page:

• dhall-haskell - Releases

For OS X, use brew to install the desired package. For example:

$ brew install dhall-json

You can build all of the packages by running:

$ cabal new-build all

And each of them with cabal new-build <package-name>, for example:

$ cabal new-build dhall

... or you can run cabal new-build within each package directory.

You can build all of the packages by running:

$ nix-build

... or you can run nix-build within each package's respective directory to build just that one package.

You can install all of the packages by running:

$ nix-env --install --file default.nix

... or you can run the same command within each package's respective directory to install just that one package.

You can develop any package by navigating to that package's directory and running:

$ nix-shell
[nix-shell]$ cabal configure
[nix-shell]$ cabal build
[nix-shell]$ cabal test

... or you can add nix: True to your ~/.cabal/config file and then you can run the same cabal commands without an explicit nix-shell:

$ cabal configure
$ cabal build
$ cabal test

You can build all of the packages with

$ stack build

And each of them with stack build <package-name>, for example:

$ stack build dhall-json

Building the website from source is currently only supported for Nix on Linux.

You can build the static assets by running:

$ nix-build --attr try-dhall

... then open ./result/index.html in your browser.

You can also download an archive containing the pre-built website from CI using this link:

• try-dhall.tar.bz2
