Write an Authoritative Source of Version Information Script

The version information for a build should be generate in just one place. A shell script is probably the most versatile. Write a script that generate the version label at stdout and name it ${PROJECT_DIR}/scripts/get-version.sh.

Pass the Version Information as a Linker Argument

version = $(shell $(CURDIR)/scripts/get-version.sh)

...

build: ...
	@go build -ldflags="-X 'example.com/myapp/internal/version.Version=$(version)'" ...

The go build command passes dynamically-generated version information to the linker. For more details, see:

go build -ldflags
