[X-Istence]

The entire OS is written in a language called C+ (now renamed to Holy C), it is an very interesting language in that it is just in time compiled. It's a mix between old school C and C++, taking some good/bad from both.

The language is fully documented too, see http://www.templeos.org/Wb/Doc/HolyC.html.

The entire OS runs in a single memory space, so processes communicating with each other is as simple as writing to that processes memory space and telling to go execute.

All of the .z files you find in the source tree directories are a gzip like algorithm that on the fly in the OS automatically unzips them, and then compiles the code contained within.

The interesting thing is that while the programs are generally just in time compiled, the main startup programs can't be, however you can easily change the OS and re-run the compiler, overwrite the already started OS and continue on. The compiler CAN write binaries but it is not recommended by the author.

And I may have spent entirely too much time in this ;-).

The author may be a schizophrenic, what he has built is kinda neat.
