## print command
print-command:
	$Q@printf "GOARCH=$(ARCH) CGO_ENABLED=1 go build -ldflags='-X "main.Version=$(VERSION)" -X "main.BuildTime=$(DATE)"' -o bin/chl-byp-srv ./server"

## Build executable
build:
	$Q# ARCH is set from `package`.
	$Q# Alternatively, run `make ARCH=<amd64|arm64> build` to override here.
	$QGOARCH=$(ARCH) CGO_ENABLED=1 go build \
		-ldflags='-X "main.Version=$(VERSION)" -X "main.BuildTime=$(DATE)"' \
		-o bin/chl-byp-srv \
		./server

## Run tests
test: build
	PATH="${PATH}:${PWD}/bin" && GOCACHE=off && go test -v -race ./...

## Generate cover report
cover:
	$Qmkdir -p .cover
	$Qrm -f .cover/*.out .cover/all.merged .cover/all.html
	$Qfor pkg in $$(go list ./...); do \
		go test -coverprofile=.cover/`echo $$pkg|tr "/" "_"`.out $$pkg; \
	done
	$Qecho 'mode: set' > .cover/all.merged
	$Qgrep -h -v "mode: set" .cover/*.out >> .cover/all.merged
ifndef CI
	$Qgo tool cover -html .cover/all.merged
else
	$Qgo tool cover -html .cover/all.merged -o .cover/all.html
endif

## Clean build files
clean:
	$Qrm -rf bin
