1 Potential projects

Looking for something to work on? Try one of these!

  • Figure out an infrastructure for including animations in the gallery and/or user manual
  • Improvements to paths: lengthening/shortening, arrowheads, etc.
  • Controlled creation of splines using an API like the one in MetaPost.

2 Backends

2.1 Cairo

Officially supported backend using cairo.

  • github repo
  • Status: active development
  • Participants: Brent Yorgey, Ryan Yates

2.2 Native SVG

A Haskell-native backend generating SVG. The intention is for this to eventually replace cairo as the "out-of-the-box" diagrams backend.

  • hackage
  • github repo
  • Status: active development
  • Participants: Deepak Jois, Ryan Yates, Felipe Lessa, Brent Yorgey

2.3 Native Postscript

Very similar to the Cairo backend but only outputting EPS.

  • github repo
  • Status: active development
  • Participants: Ryan Yates

2.4 HTML5 canvas

2.5 LaTeX/TikZ

  • original darcs repo by Scott Walck
  • updated version by Malte Harder on github
  • Status: active development
  • Participants: Scott Walck, Malte Harder

2.6 POV-Ray

A POV-Ray backend for 3D diagrams.

  • github repo
  • Status: proof of concept only, needs someone to take it over!

2.7 Wanted backends

  • OpenGL

3 Related packages and tools

3.1 command-line/interactive

See also an earlier project in a similar direction:

3.2 Build service

diagrams-builder is a library providing the ability to dynamically interpret diagrams code snippets, including utilities for creating temporary files etc. as needed. Useful for making preprocessing tools for embedding diagrams code in other document formats (e.g. LaTeX).

3.3 Fonts

The SVGFonts package implements Haskell-native font support (for fonts in the SVG-font format) that can be plugged into diagrams.

4 Other projects

4.1 gtk-toy

Michael Sloan's gtk-toy project is a framework for creating interactive gtk/cairo applications. gtk-toy-diagrams provides tools for using diagrams in conjunction with gtk-toy.

4.2 LaTeXgrapher

LaTeXGrapher is a project by Ryan Yates providing a domain-specific language for producing mathematical graphs, backed by the diagrams-postscript backend.

Deepak Jois is working on a logo interpreter written in Haskell, using diagrams as a backend.
