* Start working on getting rid of unreleased.rst Document new process in CONTRIBUTING.md, .github/pull_request_template.md and unreleased.rst (for good measure) Report the previous changelog additions here so that they're not lost in the mist of times. CHANGELOG_BEGIN - [DAML Stdlib] Added the ``NumericScale`` typeclass, which improves the type inference for Numeric literals, and helps catch the creation of out-of-bound Numerics earlier in the compilation process. - [DAML Triggers] ``emitCommands`` now accepts an additional argument that allows you to mark contracts as pending. Those contracts will be automatically filtered from the result of ``getContracts`` until we receive the corresponding completion/transaction. - [Navigator] Fixed a bug where Navigator becomes unresponsive if the ledger does not contain any DAML packages. - [Ledger-API] Add field ``gen_map`` in Protobuf definition for ledger api values. This field is used to support generic maps, an new feature currently in development. See issue https://github.com/digital-asset/daml/pull/3356 for more details about generic maps. The Ledger API will send no messages where this field is set, when using a stable version of DAML-LF. However the addition of this field may cause pattern-matching exhaustive warnings in the code of ledger API clients. Those warnings can be safely ignored until GenMap is made stable in an upcoming version of DAML-LF. - [JSON API - Experimental] CLI configuration to enable serving static content as part of the JSON API daemon: ``--static-content "directory=/full/path,prefix=static"`` This configuration is NOT recommended for production deployment. See issue #2782. - [Extractor] The app can now work against a Ledger API server that requires client authentication. See `issue #3157 <https://github.com/digital-asset/daml/issues/3157>`__. - [DAML Script] This release contains a first version of an experimental DAML script feature that provides a scenario-like API that is run against an actual ledger. - [DAML Compiler] The default DAML-LF version is now 1.7. You can still produce DAML-LF 1.6 by passing ``--target=1.6`` to ``daml build``. - [JSON API - Experimental] The database schema has changed; if using ``--query-store-jdbc-config``, you must rebuild the database by adding ``,createSchema=true``. See `issue #3461 <https://github.com/digital-asset/daml/pull/3461>`_. - [JSON API - Experimental] Terminate process immediately after creating schema. See issue #3386. - [DAML Stdlib] ``fromAnyChoice`` and ``fromAnyContractKey`` now take the template type into account. CHANGELOG_END * Document new release process to gather changelog additions * Change the release script to ignore unreleased.rst * Remove spurious unreleased.rst lines * Transition to use tags * Document new way to get changelog additions with tags * Update release/RELEASE.md Co-Authored-By: Gary Verhaegen <gary.verhaegen@digitalasset.com> * Address https://github.com/digital-asset/daml/pull/3547#discussion_r348438786 * Document correction process * Add copyright header to unreleased.sh * Update CONTRIBUTING.md Co-Authored-By: Gary Verhaegen <gary.verhaegen@digitalasset.com> * Modify CONTRIBUTING.md after @garyverhaegen-da's proposal * Make unreleased.sh run per commit and treat tags as case-insensitive * Fix documentation for replacements |

Welcome to the DAML repository!
This repository hosts all code for the DAML smart contract language and SDK, originally created by Digital Asset. 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. Once installed, to try it out, follow the quickstart guide.
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.
Contributing to DAML
We warmly welcome contributions. If you are looking for ideas on how to contribute, please browse our 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:
- Install Nix by running:
bash <(curl https://nixos.org/nix/install) - Enter
dev-envby 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. 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.
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.
