org-mode babel support #12

Closed michelk closed 11 years ago

michelk commented 11 years ago

I'm wondering, if someone has thought about creating an org-mode babel plugin; which could let you specify drawings inline org-documents.

In reports, I use org-mode and R a lot to plot stuff.

That would be extremely cool! I haven't heard anyone talk about doing this before. Do you know what is required to create a babel plugin? The diagrams-builder package (http://github.com/diagrams/diagrams-builder) is intended to make it easy to create this sort of thing.

I'm sorry, I don't have any experience in babal-plugin development; so far, I'm just a heavy user, and wanted to suggest support for diagrams.

Starting-points could be:

In ob-julia.el Gadfly (and hence Compose -- which is actually inspired by your diagrams-package) - plotting is not supported.

Maybe we can workout a solution for graphics - engines.

I took a look at the Babel framework, and I think diagrams-builder-cairo already does everything necessary. Babel takes the .org file, extracts the text of the source block, runs a function named like "org-babel-execute:diagrams" (yes, that's dynamically assembled by string concatenation) and inserts the result back into the file. So what's needed is a definition of org-babel-execute:diagrams, in lisp, that calls diagrams-builder-cairo, and returns the filepath with the image.

There should also be several related functions for handling HTML export, LaTeX export, etc, by picking the right image format.

Cool!

Re: the instructions in the README, note that cabal install diagrams-builder doesn't actually get you any of the executables such as diagrams-builder-cairo; you have to cabal install -fcairo diagrams-builder (and/or -fsvg, -fps).

Fantastic, works like a charm.

Maybe the README needs a hint how to export the whole document to pdf. I guess you have to specify :file circle.eps, then the executable shoud be dispatched to diagrams-builder-ps.

Thanks a lot
