An easy Makefile for rebar3

Here's an easy makefile for rebar3. All it does is download rebar3 into your project's './rebar3' if you don't have it already on your path. make all just tells rebar to do everything. So even people with no exposure to rebar3 can build your project.

The End.

Makefile

REBAR3_URL=https://s3.amazonaws.com/rebar3/rebar3

# If there is a rebar in the current directory, use it
ifeq ($(wildcard rebar3),rebar3)
REBAR3 = $(CURDIR)/rebar3
endif

# Fallback to rebar on PATH
REBAR3 ?= $(shell test -e `which rebar3` 2>/dev/null && which rebar3 || echo "./rebar3")

# And finally, prep to download rebar if all else fails
ifeq ($(REBAR3),)
REBAR3 = $(CURDIR)/rebar3
endif

all: $(REBAR3)
	@$(REBAR3) do clean, compile, eunit, ct, dialyzer

rel: all
	@$(REBAR3) release

$(REBAR3):
	curl -Lo rebar3 $(REBAR3_URL) || wget $(REBAR3_URL)
	chmod a+x rebar3

👍 Might be cool to do that curl/wget atomically, curl -Lo (or -LO) will definitely write a partial file if the transfer gets truncated, not sure how wget behaves.

Here's how you'd fix it for solaris (just replace rebar3 for rebar)
