# Welcome to the DAML repository!
|
|
|
|
This repository hosts all code for the [DAML smart contract language and SDK](https://daml.com/), originally created by
|
|
[Digital Asset](https://www.digitalasset.com). DAML is an open-source smart contract language for building future-proof distributed applications on a safe, privacy-aware runtime. The DAML SDK is a set of tools to help you develop applications based on DAML.
|
|
|
|
## Using DAML
|
|
|
|
To download DAML, follow [the installation instructions](https://docs.daml.com/getting-started/installation.html).
|
|
Once installed, to try it out, follow the [quickstart guide](https://docs.daml.com/getting-started/quickstart.html).
|
|
|
|
If you have questions about how to use DAML or how to build DAML-based solutions, please ask
|
|
them on [StackOverflow using the `daml` tag](https://stackoverflow.com/tags/daml).
|
|
|
|
## Contributing to DAML
|
|
|
|
We warmly welcome [contributions](./CONTRIBUTING.md). If you are looking for ideas on how to contribute, please browse our
|
|
[issues](https://github.com/digital-asset/daml/issues). To build and test DAML:
|
|
|
|
### 1. Clone this repository
|
|
|
|
```
|
|
git clone git@github.com:digital-asset/daml.git
|
|
cd daml
|
|
```
|
|
|
|
### 2. Set up the development dependencies
|
|
|
|
Our builds require various development dependencies (e.g. Java, Bazel, Python), provided by a tool called `dev-env`.
|
|
|
|
#### Linux and Mac
|
|
|
|
On Linux and Mac `dev-env` can be installed with:
|
|
|
|
1. Install Nix by running: `bash <(curl https://nixos.org/nix/install)`
|
|
2. Enter `dev-env` by running: `eval "$(dev-env/bin/dade assist)"`
|
|
|
|
If you don't want to enter `dev-env` manually each time using `eval "$(dev-env/bin/dade assist)"`,
|
|
you can also install [direnv](https://direnv.net). This repo already provides a `.envrc`
|
|
file, with an option to add more in a `.envrc.private` file.
|
|
|
|
#### Windows
|
|
|
|
On Windows you need to enable long file paths by running the following command in an admin powershell:
|
|
|
|
```
|
|
Set-ItemProperty -Path 'HKLM:\SYSTEM\CurrentControlSet\Control\FileSystem' -Name LongPathsEnabled -Type DWord -Value 1
|
|
```
|
|
|
|
Then start `dev-env` from PowerShell with:
|
|
|
|
```
|
|
.\dev-env\windows\bin\dadew.ps1 install
|
|
.\dev-env\windows\bin\dadew.ps1 sync
|
|
.\dev-env\windows\bin\dadew.ps1 enable
|
|
```
|
|
|
|
In all new PowerShell processes started, you need to repeat the `enable` step.
|
|
|
|
### 3. First build and test
|
|
|
|
We have a single script to build most targets and run the tests. On Linux and Mac run `./build.sh`. On Windows run `.\build.ps1`. Note that these scripts may take over an hour the first time.
|
|
|
|
To just build do `bazel build //...`, and to just test do `bazel test //...`. To read more about Bazel and how to use it, see [the Bazel site](https://bazel.build).
|
|
|
|
On Mac if building is causing trouble complaining about missing nix packages, you can try first running `nix-build -A tools -A cached nix` repeatedly until it completes without error.
|
|
|
|
### 4. Installing a local copy
|
|
|
|
On Linux and Mac run `daml-sdk-head` which installs a version of the SDK with version number `0.0.0`. Set the `version:` field in any DAML project to 0.0.0 and it will use the locally installed one.
|
|
|
|
On Windows:
|
|
|
|
```
|
|
bazel build //release:sdk-release-tarball
|
|
tar -vxf .\bazel-bin\release\sdk-release-tarball.tar.gz
|
|
cd sdk-*
|
|
daml\daml.exe install . --activate
|
|
```
|
|
|
|
That should tell you what to put in the path, something along the lines of `C:\Users\admin\AppData\Roaming\daml\bin`.
|
|
Note that the Windows build is not yet fully functional.
|
|
|
|
### Caching: build speed and disk space considerations
|
|
|
|
Bazel has a lot of nice properties, but they come at the cost of frequently rebuilding "the world".
|
|
To make that bearable, we make extensive use of caching. Most artifacts should be cached in our CDN,
|
|
which is configured in `.bazelrc` in this project.
|
|
|
|
However, even then, you may end up spending a lot of time (and bandwidth!) downloading artifacts from
|
|
the CDN. To alleviate that, by default, our build will create a subfolder `.bazel-cache` in this
|
|
project and keep an on-disk cache. **This can take about 10GB** at the time of writing.
|
|
|
|
To disable the disk cache, remove the following lines:
|
|
|
|
```
|
|
build:linux --disk_cache=.bazel-cache
|
|
build:darwin --disk_cache=.bazel-cache
|
|
```
|
|
|
|
from the `.bazelrc` file.
|
|
|
|
If you work with multiple copies of this repository, you can point all of them to the same disk cache
|
|
by overwriting these configs in either a `.bazelrc.local` file in each copy, or a `~/.bazelrc` file
|
|
in your home directory.
|
|
|
|
|
|
### Haskell profiling builds
|
|
|
|
To build Haskell executables with profiling enabled, pass `-c dbg` to
|
|
Bazel, e.g. `bazel build -c dbg damlc`. If you want to build the whole
|
|
SDK with profiling enabled use `daml-sdk-head --profiling`.
