Synopsis

type DotStatement = String type DotAttributes = String type NodeName = String type GraphName = String mkNode :: DotAttributes -> NodeName -> DotStatement mkEdge :: DotAttributes -> (NodeName, NodeName) -> DotStatement mkEdgeBack :: DotAttributes -> (NodeName, NodeName) -> DotStatement quote :: String -> String printRel :: (Show a, Ord a, Show b, Ord b) => GraphName -> Rel a b -> String

Representation

type DotStatement = String

The type of dot statements.

type DotAttributes = String

A list of dot attributes is represented by a string.

type NodeName = String

type GraphName = String

Printing

mkNode :: DotAttributes -> NodeName -> DotStatement

Create a node statement

mkEdge :: DotAttributes -> (NodeName, NodeName) -> DotStatement

Create an edge statement

mkEdgeBack :: DotAttributes -> (NodeName, NodeName) -> DotStatement

Create an edge statement with inverted direction

Auxilliaries

quote :: String -> String

Put quotes around a string.

printRel :: (Show a, Ord a, Show b, Ord b) => GraphName -> Rel a b -> String

Create content for dot file representing the given relation.
