Language.Dot.Parser
Description
Parsing function and abstract syntax tree for the DOT language.
The parser is implemented using happy, and so is fairly fast.
Synopsis
- parse :: [Char] -> Either String (Bool, GraphType, Maybe Name, [Statement])
- data GraphType
- data Name
- data Statement
- = EdgeStatement [Subgraph] [(Name, Name)]
- | NodeStatement Name (Maybe Port) [(Name, Name)]
- | SubgraphStatement Subgraph
- | AttributeStatement (Name, Name)
- | EdgeAttribute [(Name, Name)]
- | NodeAttribute [(Name, Name)]
- | GraphAttribute [(Name, Name)]
- data Subgraph
- data Port = Port (Maybe Name) (Maybe Compass)
- data Compass
