Original GitHub issue: https://github.com/devgianlu/go-librespot/issues/263

Description

Starting from version 0.5.1 (or later), the released binaries no longer contain the semantic version string. Instead, only the git commit hash is embedded.

Expected behavior

$ go-librespot
level=info msg="running go-librespot 0.5.3"

Actual behavior

$ go-librespot
level=info msg="running go-librespot ab178ffd"

Root cause

The Dockerfile.build ldflags changed between versions:

v0.5.0 (working):
-ldflags="-X github.com/devgianlu/go-librespot.commit=${COMMIT} -X github.com/devgianlu/go-librespot.version=${VERSION}"

v0.5.3 (current):
-ldflags "-s -w"

The -X flags that inject the version and commit variables are no longer present.

Impact

Users cannot easily determine which version is installed
The VersionNumberString() function in version.go falls back to commit hash instead of semantic version

Suggested fix

Restore the ldflags in Dockerfile.build:
-ldflags="-s -w -X github.com/devgianlu/go-librespot.commit=${COMMIT} -X github.com/devgianlu/go-librespot.version=${VERSION}"
