Card Building Contracts - Pluggable Placement Strategies
|
|
|
|
A "contract" defines the rules for how plays are placed on a card:
|
|
- Which rows to prefer for different play types
|
|
- Priority ordering of plays
|
|
- Secondary play pairing rules
|
|
- Split vs whole number preferences
|
|
- etc.
|
|
|
|
This enables different card "personalities" while using the same fitting engine.

To integrate contracts with CardBuilder, modify the builder to accept a contract:
|
|
|
|
class CardBuilder:
|
|
def __init__(self, contract: CardContract = None):
|
|
self.contract = contract or StandardContract()
|
|
self.max_splits = self.contract.max_splits_per_column()
|
|
|
|
def _get_available_rows(self, column, category: PlayCategory) -> List[int]:
|
|
# Instead of returning rows in default order,
|
|
# use the contract's preference for this category
|
|
preferred_order = self.contract.get_row_preference(category)
|
|
return [r for r in preferred_order if column.rows[r].is_empty]
|
|
|

def build_batting_card(self, ...):
|

# Use contract's priority order
|
|
for category in self.contract.get_play_priority():
|
|
plays = self._get_plays_for_category(category, chances)
|
|
for play, raw_chance in plays:
|
|
# Use contract's row preference when placing
|
|
available = self._get_available_rows(column, category)
|
|
...
|
|
|
|
This makes the fitting algorithm contract-aware without changing its core logic.
