Three new hardware-free modules holding code the scoreboard plugins carry
as identical copies (executable AST, docstrings stripped, checked across
every carrying plugin at ledmatrix-plugins 30455671). The bodies are the
plugins'; the changes are type annotations for the mypy ratchet, the
colour helpers losing their leading underscore as public free functions,
and two comments that described the plugins' files.
- src/common/sports_celebration.py: SportsCelebrationMixin, the score/win
takeover drawn by afl, football, hockey, nrl and soccer
(_draw_celebration_layout and the palette, backdrop, scenery, confetti,
crest and _fit_font steps, with their class constants), plus the colour
helpers (logo_palette, lift_color, cap_luminance, mix_color, ...). Only
the drawing: _start_celebration, _check_for_goal/_check_for_score,
_check_for_win and display() differ between the plugins and stay there.
- src/common/sports_fetch.py: SportsFetchMixin, the four SportsCore methods
identical in all nine scoreboards: _fetch_season_directly,
_background_fetches_espn_ranges, _needs_previous_day and
_wants_live_odds, with _LOOKBACK_CUTOFF_HOUR and _LIVE_ODDS_LOOKAHEAD.
_get_timezone, _extract_game_details and _fetch_data are as identical
and stay behind, for the reasons sports_shared gives (a per-plugin
import; the abstract contract); so does SportsUpcoming.__init__, since
no src/common mixin has a constructor.
- src/common/sports_card_wrappers.py: SportsCardWrappersMixin, the
seventeen sports_card delegations the eight game renderers carry (15 in
all eight, 2 in all but football, whose own versions override them).
_schema_font_size/_resolve_font_size look identical but read each
plugin's own _SCHEMA_PATH, so they stay.
Each mixin has no __init__ and creates no attributes (the host contract is
declared as annotations only), defines no name the mixins beside it
define, and documents the attributes it reads; a host-contract test
parses each and fails on an undocumented read. A method kept on a
plugin's class wins over the mixin's.
Tests: behaviour ported from the plugins' celebration, odds, lookback and
date-range tests against stub hosts carrying exactly the contract, with
crests drawn by the test (test_sports_celebration.py, test_sports_fetch.py,
test_sports_card_wrappers.py), and test_sports_stage3_parity.py, which with
LEDMATRIX_PLUGINS set compares every body with every plugin copy that is
left (58 pass against the plugins today; a copy that is gone counts as
adopted). All three modules are on the mypy ratchet, in
src/common/README.md, the CHANGELOG's Unreleased section and
SPORTS_UNIFICATION's module table. Nothing in core uses them yet.
Full suite: the same 67 failing test ids as main (Windows-only), 77 more
passing.
