Bases: object

Two-column PDF setlist renderer for a single gig.

The rendered document contains:

  • A header with gig name, date, timestamp and singer colour legend.

  • One column per two sets laid out side by side.

  • Per-song start times derived from the pre-computed schedule.

  • Live-mode annotations: [NEU] prefix for inserted songs, strikethrough for skipped songs, and [o] / [+] / [++] feedback markers.

  • Page numbers (Seite X/Y) in the bottom-right corner.

Parameter:

  • gig (Gig) – The gig to render.

  • schedule (dict[int, list[datetime]]) – Pre-computed start times per set position, as returned by calc_schedule().

  • singer_colors (dict[str, str]) – Mapping of first-name → hex colour string used to colour-code lead-singer names.
