My Emacs configuration https://git.cjennings.net/dotemacs/atom?h=load-graph-classify-end 2026-05-15T07:09:23+00:00 2026-05-15T07:09:23+00:00 Craig Jennings c@cjennings.net 2026-05-15T07:09:23+00:00 urn:sha1:d9fa8f4db2b9e6d7f610094950b460cdee146e47 The spec lays out the EMMS-removal design: package-owned track and playlist structs, a narrow backend protocol with mpv as the v1 backend, state-change hooks replacing EMMS player hooks, an overlay-based selected-track marker, a fake-backend test architecture, a quantified performance budget, a 22-step parity walk, and the migration plan. The review tracks implementation readiness: which migration-plan step is safe to start, which decisions still block the rest, and the exact spec edits required. Two decisions landed this session and are now baked into the spec: - Platform support: Linux and macOS get full features; Windows runs in degraded mode (play/stop/next/previous only) because Emacs cannot natively connect to mpv's Windows named-pipe IPC. Anyone who wants full Windows parity can wire mpvc.exe shellout or a w32-* named-pipe client as a follow-up. - File-extension scope: cj/music-file-extensions stays as-is. webm and ape files in ~/music are intentionally skipped. Socket path now references temporary-file-directory instead of a hardcoded /tmp/ prefix so the spec stays consistent with the Windows section.
