type Matrix = Rectangle Flavor Text (Maybe Text) Source #
A build matrix is represented by a rectangle, where properties that we
iterate over correspond to columns (first Text), and desired combinations
of values of those properties (second Text) correspond to rows. Each row is
then marked with the collection of options that this combination of choices
produces (the Flavor).

preferMatrix :: [Prefer] -> Matrix Source #
packageVersionMatrix :: PackageName -> [Version] -> Matrix Source #
data MatrixExpr Source #
An unevaluated build matrix expression. Matrices can contain exponentially many rows in the worst case, so it makes sense to delay converting into an evaluated representation.
Constructors
Evaluating the build matrix expression may require access to the source package DB, but if it doesn't, we'd like to avoid loading it.
