I am happy to share with fellow Orgers my recent book — Ending Malnutrition: from commitment to action — published by the Food and Agriculture Organisation of the United Nations, Rome and Tulika Books, New Delhi (http://www.fao.org/3/a-i4921e.pdf), The book was written and produced entirely in Org.

This would not have been possible without the terrific support provided by this community. Over the last few months, I have come to this mailing list with several queries about how to do something or the other, and people have very patiently provided solutions and suggestions.

I would like to thank everyone for their patience and their support.

From acknowledgements of the book:

In addition, for all the statistical work and writing, the authors relied on R (www.r-project.org), org (www.orgmode.org), and LaTeX. All three are open source projects, freely made available by very vibrant communities of developers. During the course of the work, we often drew on support from these communities.

The author just released the source code for the book!

org-scraps are interesting because I have only used Org-Mode’s tangling functionality for my Emacs initialization file. They show off a lot of the literate stuff with concise examples. Things make a lot more sense how.

Continue reading “Notes On org-scraps”

• catch the file name during export
  • Code block specific header arguments are evaluated before execution of the source block. The arguments seem to be symbols, strings, or Emacs-Lisp SEXPs.
  • Here is an example of an inline source block that gets the name of this file and returns it: "/Users/gcr/tmp/scratch.org"
  • Using Emacs-Lisp in header arguments introduces great flexibility.
• export of inline code blocks which are silent
  • Configure a document so that results are included in the document if it is being exported. This is a dynamic decision. It probably relies on org-export-current-backend now. Another example of Elisp configuring a header arg.
• mentions of file names in file contents
  • Literate example using table defintions, sh, find, and dot.
  • An example that demonstrates a lot with a little.
• inline code block
  • Develop a philosophy of what to evaluate and when.
  • They are as easy as 6 .
• recutils
  • Great example of using output to a file and a file as input via header args.
  • Demonstrate usage of Recutils.
• SQL — example reading org-mode table into sql
  • Show how Org-Mode Table data is converted to SQL data.
  • This is the essence of how data is brokered in the “BabelVM”.

• About
  • org-scraps is a collection of Org-Mode demonstrations published by Eric Schulte. All of my experience with Org-Mode Literate Programming is working on my Emacs configuration for Literate Programming. Wanting to address my limited experience I am working through each example in org-scraps. Org-Scraps is weaved to HTML files published here.
• Approach
  • Evaluate each example.
  • Verify identical result.
  • Update notes on approach.
  • After every reconfiguration re-evaluate DONE examples to verify identical result.
  • Scraps are under-documented. Important ideas are explored often without explicit mention. Sometimes it is obvious; other times not.
• simple short R block
  • “value table org replace” is probably the best :results configuration for source blocks. Replace table with scalar for in-line source blocks.
• two blocks and a table
  • Programmatically create tables with org-sbe and #+TBLFM.
• a table with tags
  • Special blocks like TBLNAME are taggable, for example with :noexport:.
• shell script output not in table
  • Evaluating a sh SB generates a table with the captured output from echo, with 1 row for each call.
  • Scalar output demands replaceable formatting.
• space around exported code blocks
  • org-babel-remove-result works no matter where the RESULT block is located. It doesn’t have to immediately follow the Source-Block.
• scheme sessions
  • ob-scheme allows two sessions with the same name when they were started with different interpreters.
