## install: install app, runs 'go install' internally
install:
	curl $(APISECRETS) --create-dirs -o $(BBDIR)/private.json
	curl $(APICERT) --create-dirs -o $(BBDIR)/butlerBurtonCert.pfx
	go install $(LDFLAGS)
	cp butler-burton.1.gz $(MANPATH)/man1

## update: updates the installed app to a new version. Basically the same as install without downloading the cert-files
update:
	go install $(LDFLAGS)
	cp butler-burton.1.gz $(MANPATH)/man1

## build: build binary, runs 'go build' internally
build:
	go build $(LDFLAGS) -o $(PROJECTNAME)

## generate and gzip manppage from markdown, uses pandoc
manpage:
	pandoc butlerburton.md -s -t man -o butler-burton.1
	gzip butler-burton.1

## build and interact with docker dev environment
dev:
	docker build -t "bb" .
	docker run -it "bb" sh
