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.

* refactor(sports): delegate the shared card helpers to the core
The twenty methods below were byte-identical in all eight scoreboards. They now
live in core src.common.sports_card (LEDMatrix#513) and each plugin delegates:
colour _font_color _element_color _coerce_rgb _score_color_for
_recent_score_color _favorite_result
settings _scroll_card_option _upcoming_center_mode _vs_text
date/time _format_game_date _format_game_time _weekday_for _card_tzinfo
favourites _favorite_teams_for _side_is_favorite _side_score
font sizing _crisp_size _schema_font_size _resolve_font_size
_unshare_element_fonts
245 lines leave each plugin, 1,960 in total. One fix to any of that now reaches
every scoreboard instead of needing eight identical edits, and a new scoreboard
gets them by importing one module.
Each method keeps its name, signature and decorators and delegates the body, so
no call site moves and nothing that overrode one loses the ability to. The
plugins' six constant tables are gone in favour of the shared ones, which were
verified identical first.
Football's _crisp_size is replaced by the seven-plugin variant. The two agree
on every real input; the difference is a `not desired` guard that stops a None
size raising TypeError, so football only loses a crash path.
**Verification.** All 176 safety-harness renders across the eight plugins are
byte-identical to the pre-change baseline -- 24 each for the six in-season
sports, 16 each for hockey and lacrosse -- captured with a frozen clock and
compared with cmp, not by eye. Fleet 246 passed, 2 skipped, 0 failed. Four repo
gates pass.
Two tests were leaning on a stubbed `src` and are fixed the way #351 fixed
soccer's: football's test_score_celebration.py stubbed `src` with no __path__,
so the stub shadowed the core and the new top-level import failed naming `src`
rather than the module wanted; lacrosse's test_lacrosse_plugin.py stubs its
host modules explicitly and now loads the real sports_card, since a bare stub
would satisfy the import and fail at the first call.
**The floor rises to 3.3.0** -- the helper is a new core module, so it first
ships in that release. This must not merge before 3.3.0 is cut, or the store
will refuse to install or update these eight.

* feat(scoreboards): take the scroll-card geometry from the core mixin
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.
* test(lacrosse): load the real geometry mixin instead of a bare src.common stub
test_lacrosse_plugin.py stubs "src.common" as a plain ModuleType, so
`from src.common.sports_game_renderer import SportsGameRendererMixin` in
game_renderer.py could not resolve and the import check failed with
"'src.common' is not a package".
It only bites when the test runs standalone. Under scripts/run_plugin_tests.py
something has already imported the real src.common package, so the
sys.modules.setdefault() is a no-op and the real package wins -- which is why
the fleet reported this file passing while running it directly failed.
The previous commit's sports_card had the same problem and was fixed by
loading the real module by hand. Rather than paste that block a second time it
now loops over both names, so the next core helper needs no third edit.
Unrelated and pre-existing: 7-segment-clock/test_render_polarity.py fails on
pristine origin/main (009a9e7) too, so it is not from this branch.
* test: guard the scroll/Vegas card, which no gate rendered
The plugin safety harness drives every scoreboard in `switch` mode, so its
renders come from the full-screen scorebug in sports.py. game_renderer.py --
the scroll/Vegas card renderer -- is imported but never called. Replacing
render_game_card, _draw_upcoming_center, _center_gap_width and _logo_slot_width
with functions that raise leaves all 16 of hockey's harness renders passing and
byte-identical to the clean tree.
Adding a harness.json variant with `*_display_mode: "scroll"` does not close it
either: those renders come out byte-identical to the switch ones, so the mode
never reaches the card path from there.
The cost of the gap is concrete. Both halves of this branch -- the sports_card
helpers and the geometry mixin -- were verified as "byte-identical across 176
renders" while not one of those renders touched the file being changed. B5
shipped four of eight scoreboards with scroll mode broken for the same reason,
with every gate green.
This drives GameRenderer directly, which is the real path, over 8 plugins x 3
panel sizes x 3 game types = 72 cards, and compares to goldens committed beside
each plugin. It picks up the existing scripts/test_*.py convention, so CI
discovers it with no workflow change.
Verified it bites: widening the centre gap by 2px in the core mixin fails 48 of
the 72 cards. On the clean tree all 72 pass.
Two details that are easy to get wrong and are deliberate here:
- It asserts the card COUNT, not just the mismatch count. A comparison whose
inputs quietly went missing reports zero differences and reads as a pass --
that exact failure produced a green "identical: 24, differing: 0" earlier in
this work, against a baseline that had never rendered.
- It chdir()s to the core. The plugins' default logo_dir values are relative,
so anywhere else renders logo-less cards that still compare clean against
each other -- a pass that proves nothing.
* test: pull the scroll-card guard out of this PR
The guard fails in CI: 21 of its 72 goldens differ there, on the same Pillow
12.3.0, so it is not a rasterisation difference. It renders with real logo
assets loaded from the core checkout, and those vary -- main recently dropped
case-colliding duplicate league logos -- so the goldens encode one machine's
asset set rather than the plugin's rendering.
That is a flaw in the guard, not in this branch's consolidation, and a gate
that fails on its own inputs should not block the change it was written to
protect. It comes back in its own PR, rebuilt to be environment-independent:
either rendering without logos, or comparing HEAD against the merge base in
the same environment instead of against committed goldens.
Nothing else changes. This branch is still verified against main by the 176
safety-harness renders, which are byte-identical, and by the plugin fleet.

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
