Documentation
A generic grid, with the given shape and contents.
type ShadedGrid = SGrid Bool Source
type CharClueGrid = SGrid (Maybe Char) Source
(!) :: (GridShape s, Ord (Cell s)) => Grid s a -> Cell s -> a Source
Lookup a grid value at a given cell. Unsafe.
fromListList :: [[a]] -> Grid Square a Source
Initialize a square grid from a list of lists. The grid might be incomplete if some rows are shorter.
clues :: GridShape s => Grid s (Maybe a) -> [(Cell s, a)] Source
For a grid with value type Maybe a, return an association
list of cells and Just values.
borders :: Eq a => Grid Square a -> [Edge] Source
The inner edges of a grid that separate unequal cells.
data OutsideClues a Source
Clues along the outside of a square grid.
Instances
| Show a => Show (OutsideClues a) |
outsideclues :: OutsideClues (Maybe a) -> [((Int, Int), a)] Source
Convert outside clues to association list mapping coordinate to value.
