I’ve really become enamored with the idea of literate programming but figured that the best way to re-introduce it to others is the same way Knuth did… with examples.
What does it look like to work this way?
Here are a few screenshots of my Emacs environment showing some of these examples.
Source code with embedded hyperlinks
Auto hiding can show just the headers
Describe diagrams with the source code
Now on to the examples. Keep in mind that each example below has an original “ORG” file as well as derivative files:
Many people have talked about the Coin Change Kata, as a way to practice our coding craft. I thought it would be fun to try it in a literate way, and this is the results. I suggest viewing the tangled web page first.
Why yes, you can keep your tests next to your code and tangle it out to separate file(s).
Emacs Init File
Being a rabid Emacs user, my
.emacs file grows regularly, and
sometimes I forget how some of the code I’ve added works… or even why
I added it in the first place. LP and Org (with its abilities to have
clickable hyperlinks) seem a natural fit.
