=== Input/Output ===
 
 
Many Haskell graphic libraries are tied to a specific rendering backend (Cairo, OpenGL, libGD etc) which makes collaboration and reuse of code and data structures very hard or impossible.
 
 
Also some dependencies are hard to fulfill. Cairo is very difficult to install on Mac OS 10.6. If you just need to generate PDF diagrams, you could choose the pure HPDF library where e.g. Hieroglyph can not be installed because of its Cairo dependence.

The diagrams framework provides an embedded domain-specific language (EDSL) for declarative drawing.

This is the diagrams wiki, for collecting tips and tricks, examples, information about related projects, and any other related information. If you are looking for more structured documentation (tutorial, user manual, API reference), see the diagrams web page. There are also bug trackers for different parts of the project.

  • 0.7 to 1.0 migration: Description of API changes that may affect diagrams 0.7 code, with explanations of how to migrate to 1.0
  • Developer wiki: notes on wanted features, style guidelines, best practices, etc.
