v0.4.0 — the refactor

v0.4.0 — the refactor 🧹

go-disc-cuer is a CLI tool and reusable Go package to generate CUE files from audio CDs, with metadata enrichment from GNUDB and MusicBrainz.

This release delivers the internals cleanup promised in v0.3.0: a new injectable Generator API, a testable disc seam, full CI, and a proper release pipeline — with no change to the CLI surface.

✨ Highlights

• New Generator API — cue.New(cfg, ...Option).Generate(Options) replaces the old generate variants. Dependencies (drive, metadata source) are now injected per-Generator instead of through package-level vars, so the whole flow is testable without hardware or network.
• Disc access abstracted behind the utils.Disc interface, enabling end-to-end tests that drive Generate from a canned TOC (no drive required).
• Stampable version — config.AppVersion is now a var (default "dev") that builds can set via -ldflags -X; library consumers keep overriding it through NewConfig.

🐛 Fixes

• gnudb: rejoin TTITLE lines wrapped across multiple lines (#9).
• musicbrainz: guard convertReleaseToDiscInfo against empty data.
• log: trace request URLs and redact the email-bearing hello= param from GNUDB URLs before logging.

🏗️ Tooling

• Makefile (deps / build / dist / test / lint / …) with a git-stamped version.
• GitHub Actions: CI running build, go test -race and golangci-lint on every push and PR, plus a release workflow that publishes the linux/amd64 artifact on tag push.

🎛️ CLI flags (unchanged)

• --overwrite — regenerate the CUE file even if it already exists
• --musicbrainz <release_id> — force a specific MusicBrainz release for metadata
• --disc-id <disc_id> — supply a custom disc ID (requires --musicbrainz)
• --device <device> — override the disc drive (default /dev/sr0)

v0.3.0 — first stable release

v0.3.0 — first stable release 🎉

go-disc-cuer is a CLI tool and reusable Go package to generate CUE files from audio CDs, with metadata enrichment from GNUDB and MusicBrainz.

⚠️ Heads up: this is not my best code — the internals grew organically and a significant refactor is planned. The public surface (CLI flags, config.NewConfig / NewDefaultConfig) is usable today, but expect package-level churn in a future major version.

✨ Features

• Disc ID calculation via libdiscid (C binding, no shelling out) — produces both MusicBrainz and GNUDB-compatible disc IDs.
• Metadata enrichment from GNUDB and MusicBrainz, with concurrent release + cover fetch.
• Cover art download and cache with status check before overwrite.
• Force / fix mode: point the tool at a specific MusicBrainz release ID to correct or regenerate a broken CUE.
• Flexible configuration via viper — config file, environment variables (DISC_CUER_*), or CLI flags, in priority order.
• Reusable as a library: config.NewConfig(appName, appVersion, baseCacheFolder) and NewDefaultConfig() let other projects embed go-disc-cuer with their own app identity and cache layout.

🎛️ CLI flags

• --overwrite — regenerate the CUE file even if it already exists
• --musicbrainz <release_id> — force a specific MusicBrainz release for metadata
• --disc-id <disc_id> — supply a custom disc ID (requires --musicbrainz)
• --device <device> — override the disc drive (default /dev/sr0)

🏗️ Architecture

Split into focused packages: cue/, discinfo/, gnudb/, musicbrainz/, config/, utils/ — each one independently importable. Internals are due for a cleanup pass.
