We have had the capability to process JSON in ABAP for some time now (refer to this blog post for an introduction). The problem is that it does not satisfy all the use cases without some effort and, therefore, there is still some scope for writing a custom JSON parser in ABAP. I recently wrote one again.
After having played around with Elasticsearch for indexing PI payloads and indexing ABAP source code, and especially after seeing the new (and now just-released) Kibana 4, it occurred to me that Elasticsearch would actually be great for business intelligence reporting.
While learning about the power of dialects in Rebol, I decided to write a little Logo interpreter to put what I learned to use.
At our client we recently went live with a solution that incorporates SAP PI. At the time we did not have TREX set up to be able to perform searches on messages. (And at the time of writing we still don’t, but we should have it soon). So as a stopgap measure, I developed a solution that uses Elasticsearch to index payloads and allows you to search them.
Rebol is a great language that all developers could benefit from. It is a real pity that it is not more widely known.
I am busy doing a little proof-of-concept solution to produce a mobile app using a BSP application as a container. In concept, this sounds easy, but there are always snags that slow down the development process, particularly trying to test AJAX calls to a remote server from a locally hosted app.
A while back I had the opportunity to investigate SAPUI5 as an option for user interfaces on our current project. Here is a quick little getting started guide that I wrote back then, partly for my own benefit in case I ever need to get started on it again.
Sometimes source code modules get very big. You can argue that this should never be the case, if you modularize your code properly, but the fact is that they do. And when they do, they sometimes become difficult to read.
One of the hurdles I face in learning a new language, as you probably do too, is that I am always looking at it from the point of view of my current context, more specifically the current set of languages, and in particular, my favorite language, which is Ruby. I end up comparing everything I look at to Ruby’s ease of expression, the way I can quickly do real practical stuff, and the amount of libraries already out there.
In my last post I briefly introduced you to the search front-end that I developed to go along with my ABAP source code indexing solution. Well, it turns out there was a severe bug in the search program which would prevent you from using the program with multiple cores (collections). So before I start the discussion, perhaps you want to grab the latest source code from the GitHub repo.
