Description

Four different representations of Dot graphs are available, all of which are based loosely upon the specifications at: http://graphviz.org/doc/info/lang.html. The `DotRepr` class provides a common interface for them (the `PrintDotRepr`, `ParseDotRepr` and `PPDotRepr` classes are used until class aliases are implemented).

Every representation takes in a type parameter: this indicates the node type (e.g. `DotGraph Int` is a Dot graph with integer nodes). Sum types are allowed, though care must be taken when specifying their `ParseDot` instances if there is the possibility of overlapping definitions. The `GraphID` type is an existing sum type that allows textual and numeric values.

If you require using more than one Dot representation, you will most likely need to import at least one of them qualified, as they typically all use the same names.

As a comparison, all four representations provide how you would define the following Dot graph (or at least one isomorphic to it) (the original of which can be found at http://graphviz.org/content/cluster). Note that in all the examples, they are not necessarily done the best way (variables rather than repeated constants, etc.); they are just there to provide a comparison on the structure of each representation.

    digraph G {

      subgraph cluster_0 {
        style=filled;
        color=lightgrey;
        node [style=filled,color=white];
        a0 -> a1 -> a2 -> a3;
        label = "process #1";
      }

      subgraph cluster_1 {
        node [style=filled];
        b0 -> b1 -> b2 -> b3;
        label = "process #2";
        color=blue
      }
      start -> a0;
      start -> b0;
      a1 -> b3;
      b2 -> a3;
      a3 -> a0;
      a3 -> end;
      b3 -> end;

      start [shape=Mdiamond];
      end [shape=Msquare];
    }

Each representation is suited for different things:

Data.GraphViz.Types.Canonical
  is ideal for converting other graph-like data structures into Dot graphs (the Data.GraphViz module provides some functions for this). It is a structured representation of Dot code.
Data.GraphViz.Types.Generalised
  matches the actual structure of Dot code. As such, it is suited for parsing in existing Dot code.
Data.GraphViz.Types.Graph
  provides graph operations for manipulating Dot graphs; this is suited when you want to edit existing Dot code. It uses generalised Dot graphs for parsing and canonical Dot graphs for printing.
Data.GraphViz.Types.Monadic
  is a much easier representation to use when defining relatively static Dot graphs in Haskell code, and looks vaguely like actual Dot code if you squint a bit.

Please also read the limitations section at the end for advice on how to properly use these Dot representations.

# Documentation

class Ord n => DotRepr dg n where #

This class is used to provide a common interface to different ways of representing a graph in Dot form.

You will most probably not need to create your own instances of this class.

The type variable represents the current node type of the Dot graph, and the `Ord` restriction is there because in practice most implementations of some of these methods require it.

Minimal complete definition

fromCanonical, getID, setID, graphIsDirected, setIsDirected, graphIsStrict, setStrictness, mapDotGraph, graphStructureInformation, nodeInformation, edgeInformation, unAnonymise

Methods

fromCanonical :: DotGraph n -> dg n #

Convert from a graph in canonical form. This is especially useful when using the functions from Data.GraphViz.Algorithms.

See `FromGeneralisedDot` in Data.GraphViz.Types.Generalised for a semi-inverse of this function.

getID :: dg n -> Maybe GraphID #

Return the ID of the graph.

setID :: GraphID -> dg n -> dg n #

Set the ID of the graph.

graphIsDirected :: dg n -> Bool #

Is this graph directed?

setIsDirected :: Bool -> dg n -> dg n #

Set whether a graph is directed or not.

graphIsStrict :: dg n -> Bool #

Is this graph strict? Strict graphs disallow multiple edges.

setStrictness :: Bool -> dg n -> dg n #

A strict graph disallows multiple edges.

mapDotGraph :: DotRepr dg n' => (n -> n') -> dg n -> dg n' #

Change the node values. This function is assumed to be injective, otherwise the resulting graph will not be identical to the original (modulo labels).

graphStructureInformation :: dg n -> (GlobalAttributes, ClusterLookup) #

Return information on all the clusters contained within this `DotRepr`, as well as the top-level `GraphAttrs` for the overall graph.

nodeInformation :: Bool -> dg n -> NodeLookup n #

Return information on the `DotNode`s contained within this `DotRepr`. The `Bool` parameter indicates if applicable `NodeAttrs` should be included.

edgeInformation :: Bool -> dg n -> [DotEdge n] #

Return information on the `DotEdge`s contained within this `DotRepr`. The `Bool` parameter indicates if applicable `EdgeAttrs` should be included.

unAnonymise :: dg n -> dg n #

Give any anonymous sub-graphs or clusters a unique identifier (i.e. there will be no `Nothing` key in the `ClusterLookup` from `graphStructureInformation`).

class PrintDot a where #

A class used to correctly print parts of the Graphviz Dot language. Minimal implementation is `unqtDot`.

Minimal complete definition

unqtDot

Methods

unqtDot :: a -> DotCode #

The unquoted representation, for use when composing values to produce a larger printing value.

toDot :: a -> DotCode #

The actual quoted representation; this should be quoted if it contains characters not permitted a plain ID String, a number or it is not an HTML string. Defaults to `unqtDot`.

unqtListToDot :: [a] -> DotCode #

The correct way of representing a list of this value when printed; not all Dot values require this to be implemented. Defaults to Haskell-like list representation.

listToDot :: [a] -> DotCode #

The quoted form of `unqtListToDot`; defaults to wrapping double quotes around the result of `unqtListToDot` (since the default implementation has characters that must be quoted).

# Helper types for looking up information within a `DotRepr`.

type ClusterLookup = Map (Maybe GraphID) ([Path], GlobalAttributes) #

The available information for each cluster; the `[`Path`]` denotes all locations where that particular cluster is located (more than one location can indicate possible problems).

type NodeLookup n = Map n (Path, Attributes) #

The available information on each `DotNode` (both explicit and implicit).

type Path = Seq (Maybe GraphID) #

The path of clusters that must be traversed to reach this spot.

graphStructureInformationClean :: DotRepr dg n => dg n -> (GlobalAttributes, ClusterLookup) #

A variant of `graphStructureInformation` with default attributes removed and only attributes usable by graph/cluster kept (where applicable).

nodeInformationClean :: DotRepr dg n => Bool -> dg n -> NodeLookup n #

A variant of `nodeInformation` with default attributes removed and only attributes used by nodes kept.

edgeInformationClean :: DotRepr dg n => Bool -> dg n -> [DotEdge n] #

A variant of `edgeInformation` with default attributes removed and only attributes used by edges kept.

# Obtaining the `DotNode`s and `DotEdges`.

graphNodes :: DotRepr dg n => dg n -> [DotNode n] #

Returns all resultant `DotNode`s in the `DotRepr` (not including `NodeAttr`s).

graphEdges :: DotRepr dg n => dg n -> [DotEdge n] #

Returns all resultant `DotEdge`s in the `DotRepr` (not including `EdgeAttr`s).

# Printing and parsing a `DotRepr`.

printDotGraph :: PrintDotRepr dg n => dg n -> Text #

The actual Dot code for an instance of `DotRepr`. Note that it is expected that ``parseDotGraph` . `printDotGraph` == `id`` (this might not be true the other way around due to un-parseable components).

parseDotGraph :: ParseDotRepr dg n => Text -> dg n #

Parse a limited subset of the Dot language to form an instance of `DotRepr`. Each instance may have its own limitations on what may or may not be parseable Dot code.

Also removes any comments, etc. before parsing.

parseDotGraphLiberally :: ParseDotRepr dg n => Text -> dg n #

As with `parseDotGraph`, but if an `Attribute` cannot be parsed strictly according to the known rules, let it fall back to being parsed as an `UnknownAttribute`. This is especially useful for when using a version of Graphviz that is either newer (especially for the XDot attributes) or older (when some attributes have changed) but you'd still prefer it to parse rather than throwing an error.

# Limitations and documentation

Printing of Dot code is done as strictly as possible, whilst parsing is as permissive as possible. For example, if the types allow it then `"2"` will be parsed as an `Int` value. Note that quoting and escaping of textual values is done automagically.

A summary of known limitations/differences:

- When creating `GraphID` values for graphs and sub-graphs, you should ensure that none of them have the same printed value as one of the node identifiers values to avoid any possible problems.
- If you want any `GlobalAttributes` in a sub-graph and want them to only apply to that sub-graph, then you must ensure it does indeed have a valid `GraphID`.
- All sub-graphs which represent clusters should have unique identifiers (well, only if you want them to be generated sensibly).
- If eventually outputting to a format such as SVG, then you should make sure to specify an identifier for the overall graph, as that is used as the title of the resulting image.
- Whilst the graphs, etc. are polymorphic in their node type, you should ensure that you use a relatively simple node type (that is, it only covers a single line, etc.).
- Also, whilst Graphviz allows you to mix the types used for nodes, this library requires/assumes that they are all the same type (but you can use a sum-type).
- `DotEdge` defines an edge `(a, b)` (with an edge going from `a` to `b`); in Dot parlance the edge has a head at `a` and a tail at `b`. Care must be taken when using the related `Head*` and `Tail*` `Attribute`s. See the differences section in Data.GraphViz.Attributes for more information.
- It is common to see multiple edges defined on the one line in Dot (e.g. `n1 -> n2 -> n3` means to create a directed edge from `n1` to `n2` and from `n2` to `n3`). These types of edge definitions are parseable; however, they are converted to singleton edges.
- It is not yet possible to create or parse edges with subgraphs/clusters as one of the end points.
- The parser will strip out comments and pre-processor lines, join together multiline statements and concatenate split strings together. However, pre-processing within HTML-like labels is currently not supported.
- Graphviz allows a node to be "defined" twice (e.g. the actual node definition, and then in a subgraph with extra global attributes applied to it). This actually represents the same node, but when parsing they will be considered as separate `DotNode`s (such that `graphNodes` will return both "definitions"). `canonicalise` from Data.GraphViz.Algorithms can be used to fix this.
