I'm new to this list so wasn't aware that you'd done all that work
with Lua. Interesting - keep meaning to find the time to have a play
with it. By the way when we ported Java to OS390 we took the decision
to compile in ascii but that's partly because so much internal JVM
code is messing with ascii strings (e.g. from the bytecode).
System.out is then a special case because it has to convert to ebcdic.
The whole ascii/ebcdic thing is such a pain though when it comes to
porting open source stuff :(
I stumbled across Lua when I was porting another FOSS product, Redis,
the NoSQL database which uses it as an embedded scripting engine. When I
took a closer look I realised
I had struck gold. It was so fast my colleagues thought I was tricking
them and running a compiled language. It's taken me about a year to port
a substantial runtime and now
I wouldn't even consider C/C++ or Java unless there was a very
compelling reason to do so. I can do just about everything Java can do
with a fraction of the code and performance
is closer than you would think. Lua spends most of it's time in fast C
code. In some cases only 10% overhead for the Lua interpreter.
If you're interested in my port drop me a line. It's more of a fork
really, there was no point trying to convince maintainers to accept MVS
patches.
Cheers,
Dave
