Lubba Encoder

Encodes Lubba workouts from/to yaml, uint8 array and base64 hash.

Can be used to create workouts that the Lubba app can import.

Workout notes

Workouts can include an optional notes string. JSON, YAML, and share hashes preserve its Unicode text, newlines, and empty strings. Null or missing notes are omitted.

Encoding version 1 stores notes as an optional trailing variable-length string after the workout parts. Workouts without notes keep exactly the same bytes and hashes. Updated decoders read old links; older decoders still read the workout but ignore the notes trailer. Older decoders do not recognize the new workoutNotes layout value (ID 72), so update consumers before sharing layouts that use it.

Map layouts

Version 1.1.19 adds the map layout value (ID 74). JSON, YAML and share hashes preserve it in full-screen, split-grid and nested workout parts. Existing IDs, including workoutNotes (72) and the ve target (73), are unchanged, so existing links keep the same encoding. Update all consumers before sharing map layouts: older decoders do not recognize ID 74. Map tiles and offline map packages are transferred separately and are not included in workout share codes.
