ghc-diagrams-builder

Hint-based build service for the diagrams graphics EDSL

'diagrams-builder' provides backend-agnostic tools for dynamically turning code into rendered diagrams, using the 'hint' wrapper to the GHC API. It supports conditional recompilation using hashing of diagrams source code, to avoid recompiling code that has not changed. It is useful for creating tools which compile diagrams code embedded in other documents. For example, it is used by the 'BlogLiterately-diagrams' package (a plugin for 'BlogLiterately') to compile diagrams embedded in Markdown-formatted blog posts. Executables specific to the cairo, SVG, postscript, and rasterific backends are included (more executables specific to other backends may be included in the future). All take an input file and an expression to render, and output an image file. If you want these executables you must explicitly enable the '-fcairo', '-fsvg', '-fpostscript', or '-frasterific' flags. A LaTeX package, 'diagrams-latex.sty', is also provided in the 'latex/' directory of the source distribution, which renders diagrams code found within 'diagram' environments. Note that 'diagrams-latex.sty' is licensed under the GPL.
