## Lint, build
all: pretty build

## Build
build: clean
	@GOOS=$(target_os) GOARCH=$(target_arch) go build -mod vendor -o ./bin/$(pkg)-$(target_os)

linux:
	@GOOS=linux GOARCH=$(target_arch) go build -mod vendor -o ./bin/$(pkg)-linux

windows:
	@GOOS=windows GOARCH=$(target_arch) go build -mod vendor -o ./bin/$(pkg)-windows.exe

## Clean binaries
clean:
	@rm -rf ./bin

## Lint
lint:
	@go fmt ./...
	@golangci-lint run

## Some tests depend on built binary, make sure you've built it beforehand.
test:
	@go test -v -mod vendor -race ./... 

coverage:
	@go test -mod vendor -coverprofile=coverage.out ./...
