Create makefile

[diogomonica]

We should create a Makefile that allows someone to clone the repo and at least do # make binaries and # make test.

Something like:

# Root directory of the project (absolute path).
ROOTDIR=$(dir $(abspath $(lastword $(MAKEFILE_LIST))))

# Base path used to install.
DESTDIR=/usr/local

# Used to populate version variable in main package.
VERSION=$(shell git describe --match 'v[0-9]*' --dirty='.m' --always)

# Project packages.
PACKAGES=$(shell go list ./... | grep -v /vendor/)

# Project binaries.
COMMANDS=actuary
BINARIES=$(addprefix bin/,$(COMMANDS))

GO_LDFLAGS=-ldflags "-X `go list ./version`.Version=$(VERSION)"

.PHONY: clean all fmt vet build binaries test setup coverage ci check help
.DEFAULT: default

all: check build binaries test ## run fmt, vet, lint, build the binaries and run the tests

# This only needs to be generated by hand when cutting full releases.
version/version.go:
    ./version/version.sh > $@

setup: ## install dependencies
    @go get -u github.com/golang/lint/golint

# Depends on binaries because vet will silently fail if it can't load compiled
# imports
vet: binaries
    @test -z "$$(go vet ${PACKAGES} 2>&1 | grep -v 'constant [0-9]* not a string in call to Errorf' | grep -v 'timestamp_test.go' | grep -v 'exit status 1' | tee /dev/stderr)"

lint: ## run go lint
    @test -z "$$(golint ./... | grep -v vendor/ | tee /dev/stderr)"

build: ## build the go packages
    @go build -i -tags "${DOCKER_BUILDTAGS}" -v ${GO_LDFLAGS} ${GO_GCFLAGS} ${PACKAGES}

test: ## run test
    @go test -parallel 8 -race -tags "${DOCKER_BUILDTAGS}" ${PACKAGES}

FORCE:

# Build a binary from a cmd.
bin/%: cmd/% FORCE
    @go build -i -tags "${DOCKER_BUILDTAGS}" -o $@ ${GO_LDFLAGS}  ${GO_GCFLAGS} ./$<

binaries: $(BINARIES) ## build binaries

clean: ## clean up binaries
    @rm -f $(BINARIES)

install: $(BINARIES) ## install binaries
    @mkdir -p $(DESTDIR)/bin
    @install $(BINARIES) $(DESTDIR)/bin

uninstall:
    @rm -f $(addprefix $(DESTDIR)/bin/,$(notdir $(BINARIES)))

I think I can do this, any objections in having a go (no pun intended)?

Sure! My relationship with Makefiles is practically non-existent
