# The dependencies of the daml workspace.
# This allows using the daml workspace externally
# from another bazel workspace.
#
# For example, another Bazel project can depend on
# targets in the daml repository by doing:
# ---
# local_repository(
#   name = "com_github_digital_asset_daml",
#   path = "/path/to/daml"
# )
# load("@com_github_digital_asset_daml//:deps.bzl", "daml_deps")
# daml_deps()
# ---
#
# A 3rd-party consumer would also need to register relevant
# toolchains and repositories in order to build targets.
# That is, copy some setup calls from WORKSPACE into the
# other WORKSPACE.
#
# Make sure to reference repository local files with the full
# prefix: @com_github_digital_asset_daml//..., as these won't
# be resolvable from external workspaces otherwise.
