This package is a repository for user contributions to the
diagrams project: generation
of specialized diagrams, fun or instructive examples, half-baked
ideas, stuff which is not sufficiently polished or general to go in
the diagrams-lib package
but is nonetheless worth sharing. Any code is welcome, as long as it
conforms to a few simple standards:
Code must be released under a BSD3 license (see the LICENSE).
You must list yourself as the maintainer.
Try to keep external dependencies to a minimum; the goal is for
diagrams-contrib to be easily installable by as many people as
possible. New dependencies will be considered on a case-by-case
basis. Dependencies involving the FFI will most likely be
rejected. If you have some cool code using diagrams which
requires big external dependencies, you should release it as a
separate package rather than including it in diagrams-contrib.
There should at minimum be a Haddock comment on the module itself,
explaining the purpose, giving some examples of use, etc. You may
also want to use
diagrams-haddock
to include some example images in the Haddock documentation; see the
diagrams-haddock documentation
and take a look at other modules in the package for examples.
It must compile with no warnings under -Wall. This may seem a bit
draconian, but you’ll get over it. If it makes you feel any
better, you are welcome to turn off specific warnings for your
module with an {-# OPTIONS_GHC -fno-warn-blah #-} pragma.
Generalized Diagrams.TwoD.IteratedSubset and added more examples.
New module Diagrams.TwoD.Layout.Grid.
API changes
Diagrams.Lens has had a lot of its lenses removed because
they’re either invalid lenses or are now in diagrams-lib.

New features
New module Diagrams.TwoD.Sunburst, for drawing sunburst
charts.
New module Diagrams.TwoD.Path.Metafont, for specifying
trails/paths using an API inspired by Metafont. Like
cubicSpline but gives you control over things like the
tension/curvature or the tangent at a given point.
New module Diagrams.TwoD.Path.Calligraphic for making simple
“calligraphic” strokes.
New module Diagrams.Lens with lenses for working with
diagrams.
Bug fixes
Diagrams.TwoD.Factorization.primeLayout has been rewritten to
avoid iterated transformations, giving a significant performance
boost.
0.7: 9 August 2013
New features
New module Diagrams.Color.HSV with an hsvBlend function for
blending colors in HSV space.
Diagrams logo code is now in Diagrams.Example.Logo.
New symmetric layout algorithm for binary trees in
Diagrams.TwoD.Layout.Tree.
Bug fixes
Fix a bug in Diagrams.TwoD.Path.Turtle which sometimes caused
it to output a doubled path (#13).
0.6.1 (23 March 2013)
New features
New Diagrams.TwoD.Path.IteratedSubset module, for constructing
paths using an “iterated subset” algorithm (repeatedly replacing
segments with a given path).
New Diagrams.TwoD.Layout.CirclePacking module for
circle-packing layout
Diagrams.TwoD.Path.Turtle: generalize runTurtle function,
and add new functions drawTurtle and sketchTurtle.
drawTurtle results in a diagram (like the old runTurtle),
and sketchTurtle yields a path (ignoring pen style commands).
Documentation
Added lots of example images using diagrams-haddock
0.6.0.4 (19 March 2013)
bump upper bound to allow QuickCheck-2.6
0.6.0.3: 27 January 2013

Update dependencies of tests
0.6: 11 December 2012
New features
New pure implementation of Turtle library, in Turtle.Internals
Diagrams.TwoD.Layout.Tree:
New renderTree' function which gives
the edge-drawing function access to the values stored at the
nodes instead of just the node positions.
The type of renderTree is generalized to work with any
QDiagram b R2 m.
Bug fixes
Tiling generation code in Diagrams.TwoD.Tilings wasn’t actually
checking whether vertexes had been already visited.
