Overview

Git-Based DAR Dependencies for dpm (Dev Fund Proposal #105) adds support for resolving Daml dependencies from Git-hosted prebuilt DAR files (.dar) in the dpm CLI.

Demo of Git DAR dependencies in dpm

The main idea behind the feature is that dpm can take a DAR file from Git the same way it already takes one from OCI. Adding a Git-based DAR file to daml.yaml makes dpm fetch it and pin it so later builds use the cached file.

Content

Declaring Git dependencies: how to write the git: lines, use repository aliases and GitHub release assets, and verify pins.
Technical design: how fetch and pin work, and why resolve never uses the network.
Testing with a demo project: a demo you can build and run against real Git DAR dependencies.

Deliverables

This page compiles technical documentation and design for the functionality. Because the functionality is a natural addition to dpm and its existing documentation, the delivery expands the current solution and documentation:

PR to dpm: feature development, technical documentation, and tests for each new functionality added.
PR to Canton Foundation Docs: public-facing documentation for dpm users.

Milestone 1 and evidence comments were posted in issue #666 from canton-dev-fund.
