#!/usr/bin/env python3
# A documented one-shot, not part of the OCaml build (spec's "no hand-written
# JSON parser" rule is about colitur's OWN sexp format -- reading someone
# else's JSON needs a reader, same reasoning as tools/bootstrap_sanctoral.ml's
# own header comment on its INI reader). Task 16: extracts the missalemeum
# oracle fixture (test/fixtures/missalemeum-ef-2026-2027.txt) that
# test/test_oracle.ml compares colitur against -- there is no JSON library in
# this project's frozen deps, so the fixture is shaped here, once, outside
# the test, exactly as test/test_differential.ml's lectio fixture already is
# (see that file's own header comment).
#
# Usage:
# python3 tools/extract_missalemeum_oracle.py <snapshot-dir> <out-file>
#
# <snapshot-dir> is ~/git/projects/lectio/sources/ already unpacked (`tar xzf
# snapshot.tar.gz` in that directory -- lectio's own scripts/snapshot-
# sources.sh does this), so <snapshot-dir>/missalemeum/en/YYYY-MM-DD.json
# exists for every day.
#
# One line per day, pipe-separated:
# date|rank|colors|title|tempora|commemorations|displaced|n_masses
#
# - rank/colors/title/tempora/commemorations/displaced are info.rank,
# info.colors (sorted, concatenated, e.g. "pv"), info.title, info.tempora
# ("-" for JSON null), the ";"-joined titles of info.commemorations and
# info.displaced ("-" for an empty list), verbatim from the JSON's own
# English strings -- not translated or slugified, so the comparator (and a
# human auditor) can match colitur's own celebration names against them.
# - n_masses is len(the day's JSON array). Four days (Christmas, All Souls)
# carry more than one Mass; entry[0]'s info block is used throughout (rank/
# colors/tempora/commemorations/displaced are IDENTICAL across every Mass
# of the same day for all 730 days -- checked below, not assumed; see the
# task report for why entry[0] loses nothing).
# - Spaces in tempora are turned to "_" (matching the "no field has an
# internal space" convention test/fixtures/lectio-ef-2005-2050.txt already
# uses, so this fixture can be read the same simple way -- split on '|',
# not on whitespace, so title/commemoration/displaced text keeps its own
# spaces; only tempora, which nothing in this project parses further than
# pass-through display, is space-collapsed for a cheap column-count check).
