new Lua features

["Carl Kopin" <ckopin@xxxxxxxxxxxxxxxxxxx>]

Robin,
Thanks for your fixes, I like your ideas, but I think, I am missing
something.
Here is what I found:

The exit_pre() and exit_post() - neither program actually stopped the
running, they passed through these commands and executed the following
scripts.

By the way, talking about the exit_xxx() futures; as for me, it is quite
obvious that exit_post() should exit and close the postprocessor, but
there may be instances that one would like to stop the postprocessor
without closing it in order to verify that a task did what was intended
and possibly take additional measurements manually, so adding something
like this exit_post(halt) or better one might be helpful. Keeping the
exit_post() as initially intended is still reasonable. You may also
consider to include similar idea to the preprocessor. I think, this
would stop running the script without possibility of restarting it, but
that's OK. 

Am I too picky on you?
Well, I really appreciate what you have done for us anyway :-)
Carl

If your feeling brave then give the 3.1 patch a try it has a way of
passing
variables to the post processor
(available from the femm files section)

the new version of run_post accepts variables as so

in the pre-processor script try

run_post("c:\\my-lua-script.lua","-lua-var=filename=myfilename","-lua-va
r=ms
g=hello-world")

then in the post processor

try
_ALERT(msg)
_ALERT(filename)

and you will see hello world for msg and myfilename for filename

You can use these variables any where you would normally use variables
in an
lua script !!

All variables are passed as strings so you will have to use internal
conversion routines to get numbers out

Hopefully this will make peoples lives a lot easier than using temp
files to
pass data around
(There is no way of passing data back the other way however without
using
temp files)
