## Basic targets.
##
##   This Makefile wraps basic build and test targets for ease-of-use. Bazel
##   is run inside a canonical Docker container in order to simplify up-front
##   requirements.
##
##   There are common arguments that may be passed to targets. These are:
##     OPTIONS - Build or test options.
##     TARGETS - The bazel targets.
##     ARGS    - Arguments for run or sudo.
##
##   Additionally, the copy target expects a DESTINATION to be provided.
##
##   For example, to build runsc using this Makefile, you can run:
##     make build OPTIONS="" TARGETS="//runsc"'
##
help: ## Shows all targets and help from the Makefile (this message).

				printf "%s\n", $$2; \

build: ## Builds the given $(TARGETS) with the given $(OPTIONS). E.g. make build TARGETS=runsc
	@$(call build,$(OPTIONS) $(TARGETS))
.PHONY: build

test: ## Tests the given $(TARGETS) with the given $(OPTIONS). E.g. make test TARGETS=pkg/buffer:buffer_test
	@$(call test,$(OPTIONS) $(TARGETS))
.PHONY: test

copy: ## Copies the given $(TARGETS) to the given $(DESTINATION). E.g. make copy TARGETS=runsc DESTINATION=/tmp
	@$(call copy,$(TARGETS),$(DESTINATION))
.PHONY: copy

run: ## Runs the given $(TARGETS), built with $(OPTIONS), using $(ARGS). E.g. make run TARGETS=runsc ARGS=-version
	@$(call run,$(TARGETS),$(ARGS))
.PHONY: run

sudo: ## Runs the given $(TARGETS) as per run, but using "sudo -E". E.g. make sudo TARGETS=test/root:root_test ARGS=-test.v
	@$(call sudo,$(TARGETS),$(ARGS))

##
## Development helpers and tooling.
##
##   These targets faciliate local development by automatically
##   installing and configuring a runtime. Several variables may
##   be used here to tweak the installation:
##     RUNTIME         - The name of the installed runtime (default: $BRANCH_NAME).
##     RUNTIME_DIR     - Where the runtime will be installed (default: temporary directory with the $RUNTIME).
##     RUNTIME_BIN     - The runtime binary (default: $RUNTIME_DIR/runsc).
##     RUNTIME_LOG_DIR - The logs directory (default: $RUNTIME_DIR/logs).
##     RUNTIME_LOGS    - The log pattern (default: $RUNTIME_LOG_DIR/runsc.log.%TEST%.%TIMESTAMP%.%COMMAND%).
##     RUNTIME_ARGS    - Arguments passed to the runtime when installed.
##     STAGED_BINARIES - A tarball of staged binaries. If this is set, then binaries
##                       will be installed from this staged bundle instead of built.
##     DOCKER_RELOAD_COMMAND - The command to run to reload Docker. (default: sudo systemctl reload docker).
