Its taken an enormous effort, but we are finally close to having the same code base compile on Windows, OSX and Linux.

The core HL7 code was not difficult but in the end we have implemented at lot of the threading and synchronisation calls that are in windows, but not in *nix. It have also meant implementing many complex routines in pure pascal. This has included a HTTP server, RSA/IDEA encryption and JSON and XML parsers! It has also driven us to the Web 2.0 world, which has been a pleasant drive!

Credit must be given to the amazing ability of Peter Tattam, who has been slaving away at this task on and off for the last few months on and off. His ability to work with low level code is second to none.

So where are we up to – we have a native pascal version of Capricorn, running and working well on OSX with the same source code base as the windows version. At this stage its not using any special libraries and is a single executable. We have dissected out or implemented all the windows specific code and are close to doing some beta testing. The scary bit is that in its current form its 300K lines of object pascal code… Luckily its mostly code that has been under extensive use in the Windows world for quite a while.

So here is a very raw low res sneak peak of Capricorn running as a Native OSX appication. It really isn’t much to look at as this is pure messaging infrastructure, but its important vital infrastructure if we are going to move into a world of real time standards based HL7 messaging!
