EMMS Smart Watch Feature Requirements

GOAL

Enable EMMS in Emacs to:

• Remember the last playback position (per media file)
• Resume from last position automatically
• Visually annotate media browser/dired/ibuffer with progress
• Indicate completed (fully watched) files

TASKS

TODO Persistent Storage for Play States

• Store last played position, duration per file
• Use a sexp file, e.g., an alist
• Ensure efficient lookup/update

TODO Hook Integration in EMMS

• On playback stop/change, save position and duration
• On playback start, check and resume from last position if available

TODO Visual Annotation in Media Browser

• For each video file, display watch percentage visually
• Color or icon for completed files (e.g., 95%+ watched)
• Integrate with dired/ibuffer/EMMS browser

TODO Mark Files as Completed

• If user finishes a file (end reached or high %), update state
• Option to manually mark as complete

TODO User Configuration

• Set threshold for “completed” (e.g., 95% watched)
• Customize appearance

TODO Testing & Edge Cases

• File renamed/moved
• Partial plays
• Support for non-video formats

TODO Documentation

• Usage instructions
• How to clear/reset a file’s watch history

NOTES

• Use EMMS hooks for integration
• Make all user-facing features easily customizable
• Consider extensibility for other media types
