Canonical version information injection target for Go's -ldflags.
Use this snippet to inject Git-based version information into binaries:
COMMIT_ID = $(shell git describe --tags --always --dirty=-dev)
COMMIT_UNIX = $(shell git show -s --format=%ct HEAD)
BUILD_COUNT = $(shell git rev-list --count HEAD)
BUILD_UNIX = $(shell date +%s)
LDFLAGS = \
-X 'github.com/digineo/goldflags.commitID=$(COMMIT_ID)' \
-X 'github.com/digineo/goldflags.commitUnix=$(COMMIT_UNIX)' \
-X 'github.com/digineo/goldflags.buildCount=$(BUILD_COUNT)' \
-X 'github.com/digineo/goldflags.buildUnix=$(BUILD_UNIX)'
binary: main.go
go build -ldflags "$(LDFLAGS)"You can include the goldflags.mk to keep your Makefile tidy (cf.
_examples/Makefile).
