Description

The generalised Dot representation most closely matches the implementation of actual Dot code, as it places no restrictions on ordering of elements, etc. As such it should be able to parse any existing Dot code (taking into account the parsing limitations/assumptions).

The sample graph could be implemented (this is actually a prettied version of parsing in the Dot code) as:

DotGraph { strictGraph = False
         , directedGraph = True
         , graphID = Just (Str "G")
         , graphStatements = Seq.fromList [ SG $ DotSG { isCluster = True
                                                       , subGraphID = Just (Int 0)
                                                       , subGraphStmts = Seq.fromList [ GA $ GraphAttrs [style filled]
                                                                                      , GA $ GraphAttrs [color LightGray]
                                                                                      , GA $ NodeAttrs [style filled, color White]
                                                                                      , DE $ DotEdge "a0" "a1" []
                                                                                      , DE $ DotEdge "a1" "a2" []
                                                                                      , DE $ DotEdge "a2" "a3" []

                                          , SG $ DotSG { isCluster = True
                                                       , subGraphID = Just (Int 1)
                                                       , subGraphStmts = fromList [ GA $ NodeAttrs [style filled]

class DotRepr dg n => FromGeneralisedDot dg n where Source #

This class is useful for being able to parse in a dot graph as a generalised one, and then convert it to your preferred representation.

This can be seen as a semi-inverse of fromCanonical.

Methods

fromGeneralised :: DotGraph n -> dg n Source #

Sub-components of a DotGraph.

Re-exported from Data.GraphViz.Types.

data GraphID Source #

A polymorphic type that covers all possible ID values allowed by Dot syntax. Note that whilst the ParseDot and PrintDot instances for String will properly take care of the special cases for numbers, they are treated differently here.

Constructors

Str Text 
Num Number 

data GlobalAttributes Source #

Represents a list of top-level list of Attributes for the entire graph/sub-graph. Note that GraphAttrs also applies to DotSubGraphs.

Note that Dot allows a single Attribute to be listed on a line; if this is the case then when parsing, the type of Attribute it is determined and that type of GlobalAttribute is created.
