Pre-built binaries
You can download pre-built binaries for Windows, OS X and Linux on the release page:
You can also install binaries for OS X using brew
, like this:
$ brew install dhall-json
You can also install pre-built Linux binaries for master
using Nix using
Nix's channel mechanism by following the instructions at this link:
To install the Nix build products without a channel, configure your machine to
use cache.dhall-lang.org
, as described in the nix section and then
visit one of the following links:
- https://hydra.dhall-lang.org/job/dhall-haskell/master/linux-dhall/latest
- https://hydra.dhall-lang.org/job/dhall-haskell/master/linux-dhall-bash/latest
- https://hydra.dhall-lang.org/job/dhall-haskell/master/linux-dhall-json/latest
- https://hydra.dhall-lang.org/job/dhall-haskell/master/linux-dhall-yaml/latest
- https://hydra.dhall-lang.org/job/dhall-haskell/master/linux-dhall-nix/latest
- https://hydra.dhall-lang.org/job/dhall-haskell/master/linux-dhall-lsp-server/latest
- https://hydra.dhall-lang.org/job/dhall-haskell/master/linux-dhall-docs/latest
- https://hydra.dhall-lang.org/job/dhall-haskell/master/linux-dhall-toml/latest
- https://hydra.dhall-lang.org/job/dhall-haskell/master/linux-dhall-csv/latest
You can then click the "Help" button in the bottom right corner, which will
show you a nix-env
command that you can run to install the prebuilt
executable.
If you have the jq
command-line tool installed then you can do this in one
command by running:
$ nix-env -i "$(curl -L https://hydra.dhall-lang.org/job/dhall-haskell/master/linux-dhall/latest/api/get-info | jq -r .outPath)"
These instructions also work for any pull request, too, by replacing master
with the pull request number for any of the above URLs.
Pre-built containers
Prebuilt containers for the latest release available from Docker Hub:
... but if you want to obtain containers for bleeding-edge builds, you can download image archives for each package using the following URLs:
- https://hydra.dhall-lang.org/job/dhall-haskell/master/image-dhall/latest/download/1/docker-image-dhall.tar.gz
- https://hydra.dhall-lang.org/job/dhall-haskell/master/image-dhall-bash/latest/download/1/docker-image-dhall-bash.tar.gz
- https://hydra.dhall-lang.org/job/dhall-haskell/master/image-dhall-json/latest/download/1/docker-image-dhall-json.tar.gz
- https://hydra.dhall-lang.org/job/dhall-haskell/master/image-dhall-yaml/latest/download/1/docker-image-dhall-yaml.tar.gz
- https://hydra.dhall-lang.org/job/dhall-haskell/master/image-dhall-lsp-server/latest/download/1/docker-image-dhall-lsp-server.tar.gz
- https://hydra.dhall-lang.org/job/dhall-haskell/master/image-dhall-nix/latest/download/1/docker-image-dhall-nix.tar.gz
- https://hydra.dhall-lang.org/job/dhall-haskell/master/image-dhall-docs/latest/download/1/docker-image-dhall-docs.tar.gz
- https://hydra.dhall-lang.org/job/dhall-haskell/master/image-dhall-toml/latest/download/1/docker-image-dhall-toml.tar.gz
- https://hydra.dhall-lang.org/job/dhall-haskell/master/image-dhall-csv/latest/download/1/docker-image-dhall-csv.tar.gz
You can then load and run one of these archives like so:
$ NAME="dhall"
$ curl --location --remote-name "https://hydra.dhall-lang.org/job/dhall-haskell/master/image-${NAME}/latest/download/1/docker-image-${NAME}.tar.gz"
$ docker load < "docker-image-${NAME}.tar.gz"
...
Loaded image: dhall:vx95jiijmp2i07f5ynl8h6sllf34jggz
$ docker run --interactive --rm dhall:vx95jiijmp2i07f5ynl8h6sllf34jggz dhall <<< '2 + 2'

These instructions also work for any pull request, too, by replacing master
with the pull request number for any of the above URLs.
Building from source
For all of the following instructions, make sure to first check out the
dhall-lang
submodule:
$ git submodule init
$ git submodule update
cabal
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.
nix
You will probably want to use the shared caches hosted at cache.dhall-lang.org
and dhall.cachix.org
when doing Nix development. This is not required, but
this will save you a lot of time so that you don't have to build as many
dependencies from scratch the first time.
If your operating system is NixOS then you can add the cache using these NixOS configuration options to access dhall packages from your declarative configuration file:
nix = {
binaryCaches = [
"https://cache.nixos.org"
"https://cache.dhall-lang.org"
"https://dhall.cachix.org"
];
binaryCachePublicKeys = [
"cache.dhall-lang.org:I9/H18WHd60olG5GsIjolp7CtepSgJmM2CsO813VTmM="
"dhall.cachix.org-1:8laGciue2JBwD49ICFtg+cIF8ddDaW7OFBjDb/dHEAo="
];
};
If you are not using NixOS, then instead modify your /etc/nix/nix.conf
file
by adding the following options.
Using Nix 2.0 or later:
trusted-public-keys = cache.nixos.org-1:6NCHdD59X431o0gWypbMrAURkbJ16ZPMQFGspcDShjY= cache.dhall-lang.org:I9/H18WHd60olG5GsIjolp7CtepSgJmM2CsO813VTmM= dhall.cachix.org-1:8laGciue2JBwD49ICFtg+cIF8ddDaW7OFBjDb/dHEAo=
substituters = https://cache.nixos.org https://cache.dhall-lang.org https://dhall.cachix.org
Using earlier Nix versions (i.e. Nix 1.*
):
binary-cache-public-keys = cache.nixos.org-1:6NCHdD59X431o0gWypbMrAURkbJ16ZPMQFGspcDShjY= cache.dhall-lang.org:I9/H18WHd60olG5GsIjolp7CtepSgJmM2CsO813VTmM= dhall.cachix.org-1:8laGciue2JBwD49ICFtg+cIF8ddDaW7OFBjDb/dHEAo=
binary-caches = https://cache.nixos.org https://cache.dhall-lang.org https://dhall.cachix.org
Since many tests require HTTP access, you should also add this setting to
your /etc/nix/nix.conf
:
sandbox = false
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.
If you prefer installing the binaries locally in a nix shell environment
instead, just run nix-shell
in the top-level directory. This option provides
additional flexibility with respect to overriding some of the default parameters
(e.g. the compiler version), which makes it particularly useful for developers.
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
stack
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
Profiling
Say you want to profile the dhall-to-json
executable.
Build the containing package with profiling options:
$ stack build --profile --library-profiling dhall-json
Run the executable on your input. For example:
$ stack exec --profile --rts-options -p -- dhall-to-json <<< 'True && False'
This generates a dhall-to-json.prof
file in your current directory.
Build the website
If you don't need to change the GHCJS code, then switch to the dhall-lang
repository and follow these instructions instead:
If you do need to test changes to the GHCJS code (i.e. the
[./dhall-try
](./dhall-try) subdirectory) then stay within this repository, but
edit the dhall/dhall-lang
submodule to make the following change:
diff --git a/release.nix b/release.nix
--- a/dhall/dhall-lang/release.nix
+++ b/dhall/dhall-lang/release.nix
let
json = builtins.fromJSON (builtins.readFile ./nixops/dhall-haskell.json);
- dhall-haskell =
- pkgs.fetchFromGitHub {
- owner = "dhall-lang";
-
- repo = "dhall-haskell";
-
- inherit (json) rev sha256 fetchSubmodules;
- };
+ dhall-haskell = ../..;
in
import "${dhall-haskell}/default.nix";
... and then build the website by running:
$ nix build --file dhall/dhall-lang/release.nix website
... which will incorporate any GHCJS-related changes you make
