feat(sports): share the scroll-card geometry the scoreboards all duplicate - #514
Merged
Conversation
…icate The card helpers moved to src/common/sports_card.py, which shared the eight scoreboards' settings lookups. Their *geometry* stayed duplicated: nine methods deciding how wide the centre strip is, how much room each logo gets, and where an upcoming card's date and time land. Five were byte-identical in all eight plugins; the other four were identical in seven, each with a different single outlier. That shape is why this is a mixin and not free functions. Comparing executable ASTs against the eight plugins, 67 of the 70 method bodies are inherited unchanged and 3 become ordinary overrides -- baseball keeps its own _logo_slot_width and _draw_upcoming_game_status, hockey its own _upcoming_date_and_time. No per-sport branching goes inside the base. It deliberately has no __init__ and no state. The plugins' constructors differ six ways and none of it is worth unifying, so adoption is one line on the class statement plus deleting what now comes from here. Placed in src/common/ rather than src/base_classes/sports/ on purpose: importing that package pulls core.py -> DisplayManager -> rgbmatrix, and this is pure geometry that must not drag a hardware import into every plugin that uses it. It sits next to sports_card.py, which the same plugins already use. Only _SCORE_PROBE varies between plugins, so leagues that reach three digits a side override that one ClassVar; the four gap constants are identical everywhere. The tests drive the mixin through a host that provides exactly the surface the module docstring names and nothing else, so the mixin growing a new self.* dependency the plugins do not have fails the contract test rather than shipping.

Companion to the sports_card adoption in the previous commit, and the second half of the same idea. That one shared the settings lookups; this one shares the geometry those settings drive. Nine methods -- _score_reserve_width, _center_gap_width, _logo_slot_width, _logo_cache_key, _layout_offset, _upcoming_date_and_time, _draw_upcoming_center, _draw_upcoming_game_status and set_rankings_cache -- plus five class constants were being maintained in eight copies. They now come from src.common.sports_game_renderer.SportsGameRendererMixin (ChuckBuilds/LEDMatrix#514). Comparing executable ASTs before the change, 67 of the 70 bodies were already identical to the mixin's. The three that were not stay behind as ordinary overrides: baseball's _logo_slot_width and _draw_upcoming_game_status, and hockey's _upcoming_date_and_time. Of the constants only _SCORE_PROBE varies, so afl and basketball -- the two leagues that reach three digits a side -- keep theirs and the rest inherit. This rides in the same version bump as the sports_card adoption rather than taking a second one. Both need core 3.3.0, so splitting them would mean shipping every scoreboard twice for one floor. Also drops the datetime/timezone/ZoneInfo imports that the previous commit orphaned when the date and time formatting moved to sports_card. Hockey still parses timestamps in its override, so it keeps them. Nothing drawn changes: the bodies were moved rather than rewritten.
…nder A center_gap of inf passes `isinstance(x, (int, float)) and x >= 0` unharmed and then raises OverflowError out of int(). The surrounding guards caught only (TypeError, ValueError), so it escaped and took the whole card render with it. The same holds for center_gap_ratio, the two clamp bounds, and layout offsets, where "inf" arrives as a string and float() is happy to produce it. Four of the five paths crashed; only a NaN ratio happened to survive, by accident of min/max rather than by design. This is pre-existing behaviour -- the bodies moved here verbatim from the eight plugins and every one of them has it today. Fixing it in the mixin fixes it in all eight at once, which is the argument for the mixin. Guarded with math.isfinite() before any int()/round(), falling back to the same defaults the finite paths already use, plus OverflowError added to the except clauses as a backstop. Ordinary settings are untouched: all 192 scroll-card renders (8 plugins x 8 panel sizes x 3 game types) stay byte-identical to pristine main. Found by CodeRabbit on #514 and confirmed by running it before fixing.

Follow-on to #513. Independent of it — this branch is cut from
main, not stacked — but both belong in the same core release, since the eight scoreboards will adopt them together under oneledmatrix_min_versionfloor.What this adds
src/common/sports_game_renderer.py— a mixin carrying the nine scroll/Vegas card geometry methods that the eight sports scoreboards each keep their own copy of:_score_reserve_width,_center_gap_width,_logo_slot_width,_logo_cache_key,_layout_offset,_upcoming_date_and_time,_draw_upcoming_center,_draw_upcoming_game_status,set_rankings_cacheWhy a mixin
Comparing executable ASTs (docstrings, comments and annotations ignored) against all eight plugins:
The three are baseball's
_logo_slot_widthand_draw_upcoming_game_status, and hockey's_upcoming_date_and_time— each an ordinary override. Nothing per-sport goes inside the base.Of the five class constants, four (
CENTER_GAP_RATIO,CENTER_GAP_MIN_PX,CENTER_GAP_MAX_PX,_SCORE_LOGO_GUTTER_PX) are identical across all eight. Only_SCORE_PROBEvaries, so leagues that can reach three digits a side override that one ClassVar.Two deliberate choices
No
__init__, no state. The plugins' constructors differ six ways and none of that is worth unifying. Adoption is one line on the class statement plus deleting the methods that now come from here — which is what keeps it safe to roll out one plugin at a time.src/common/, notsrc/base_classes/sports/. Importing that package pullscore.py→DisplayManager→rgbmatrix. This is pure geometry and must not drag a hardware import into every plugin that uses it. It sits besidesports_card.py, which the same plugins already import.Tests
31 new tests. They drive the mixin through a host class that provides exactly the surface the module docstring names and nothing more — so if the mixin later grows a
self.*dependency the plugins do not actually have, the contract test fails instead of it shipping.No plugin changes here; adoption is a separate PR in
