Module : Data.GraphViz.Attributes
Description : Definition of the Graphviz attributes.
Copyright : (c) Matthew Sackman, Ivan Lazar Miljenovic
License : 3-Clause BSD-style
Maintainer : Ivan.Miljenovic@gmail.com
This module defines the various attributes that different parts of
a Graphviz graph can have. These attributes are based on the
documentation found at:
<http://graphviz.org/doc/info/attrs.html>
For more information on usage, etc. please see that document.
A summary of known current constraints\/limitations\/differences:
* There might still be a few cases where quotes are still not
escaped/parsed correctly; if you find such a situation, please
let me know; however, you should be able to use 'String' values
directly without having to worry about when quotes are required
or extra escaping of quote characters as 'PrintDot' and
'ParseDot' instances for 'String' should take care of that
for you.
* Note that for an edge, in /Dot/ parlance if the edge goes from
/A/ to /B/, then /A/ is the tail node and /B/ is the head node
(since /A/ is at the tail end of the arrow).
* ColorList and PointfList are defined as actual lists (but
'LayerList' is not). Note that for the Color 'Attribute' for
node values, only a single Color is valid; edges are allowed
multiple colors with one spline/arrow per color in the list (but
you must have at least one 'Color' in the list). This might be
changed in future.
* Style is implemented as a list of 'StyleItem' values; note that
empty lists are not allowed.
* A lot of values have a possible value of @none@. These now
have custom constructors. In fact, most constructors have been
expanded upon to give an idea of what they represent rather than
using generic terms.
* @PointF@ and 'Point' have been combined, and feature support for pure
'Int'-based co-ordinates as well as 'Double' ones (i.e. no floating
point-only points for Point). The optional '!' and third value
for Point are not available.
* 'Rect' uses two 'Point' values to denote the lower-left and
top-right corners.
* The two 'LabelLoc' attributes have been combined.
* The defined 'LayerSep' is not used to parse 'LayerRange' or
'LayerList'; the default (@[' ', ':', '\t']@) is instead used.
* @SplineType@ has been replaced with @['Spline']@.
* Only polygon-based 'Shape's are available.
* 'PortPos' only has the 'CompassPoint' option, not
@PortName[:CompassPoint]@ (since record shapes aren't allowed,
and parsing HTML-like labels could be problematic).
* Not every 'Attribute' is fully documented/described. However,
all those which have specific allowed values should be covered.
* Deprecated 'Overlap' algorithms are not defined.
* The global @Orientation@ attribute is not defined, as it is
difficult to distinguish from the node-based 'Orientation'
'Attribute'; also, its behaviour is duplicated by 'Rotate'.

These attributes have been implemented in a /permissive/ manner:
that is, rather than split them up based on which type of value
they are allowed, they have all been included in the one data type,
with functions to determine if they are indeed valid for what
they're being applied to.
To interpret the /Valid for/ listings:
[@G@] Valid for Graphs.
[@C@] Valid for Clusters.
[@S@] Valid for Sub-Graphs (and also Clusters).
[@N@] Valid for Nodes.
[@E@] Valid for Edges.
The /Default/ listings are those that the various Graphviz commands
use if that 'Attribute' isn't specified (in cases where this is
/none/, this is equivalent to a 'Nothing' value; that is, no value
is used). The /Parsing Default/ listings represent what value is
used (i.e. corresponds to 'True') when the 'Attribute' name is
listed on its own in /Dot/ source code.

Some 'Attribute's (mainly label-like ones) take a 'String' argument
that allows for extra escape codes. This library doesn't do any
extra checks or special parsing for these escape codes, but usage
of 'EscString' rather than 'String' indicates that the Graphviz
tools will recognise these extra escape codes for these
'Attribute's.
The extra escape codes include (note that these are all 'String's):
[@\\N@] Replace with the name of the node (for Node 'Attribute's).
[@\\G@] Replace with the name of the graph (for Node 'Attribute's)
or the name of the graph or cluster, whichever is
applicable (for Graph, Cluster and Edge 'Attribute's).
[@\\E@] Replace with the name of the edge, formed by the two
adjoining nodes and the edge type (for Edge 'Attribute's).
[@\\T@] Replace with the name of the tail node (for Edge
'Attribute's).
[@\\H@] Replace with the name of the head node (for Edge
'Attribute's).
[@\\L@] Replace with the object's label (for all 'Attribute's).
Also, if the 'Attribute' in question is 'Label', 'HeadLabel' or
'TailLabel', then @\\n@, @\\l@ and @\\r@ split the label into lines
centered, left-justified and right-justified respectively.
