JSON to ABAP data structure program

April 2nd, 2012

On my current project, I had to write some ABAP code to convert a (deep) ABAP structure to JSON. I have seen at least two projects out there that do the same thing, but nothing that converts JSON to ABAP. So I set out to produce an ABAP program to do this.

Unicode in ABAP

February 3rd, 2012

Having worked with ABAP most of my career, I have not had to care a lot (if ever) about Unicode, maybe due to the fact that I work in a country where all SAP systems only use English (with very, very rare exceptions).

Javascript-style object-value assignment in Ruby

January 23rd, 2012

While I was working in Javascript extensively for a project, one of the things I really liked about it was how you could use the dot notation to access members of an object, just as you would call methods. After that, I would often find myself in an IRB shell, absent-mindedly trying to do the same thing with a Ruby Hash, only to be thrown a NoMethodError.

Nice web server script to serve any directory using WEBrick

June 22nd, 2011

At present, I am doing some web development in the form of a rich Javascript client. Now I have a need to serve up pages locally, but I don’t want to run a heavy web server just for that. So I wrote a little Ruby script to allow me to start a WEBrick server in any directory on the fly, which is great for testing content locally.

Here is a post that I wrote in October 2009. I think the reason why I never published it was because I wanted to first investigate what other (standard) possibilities there were  for providing this functionality, and I was afraid I would be embarrassed by some naive statements made in here. Anyway, for what it’s worth, here it is. (I don’t know what happened to Illustration 1. If I find it, I will try and put it back).
