Re: Lua need 1M memory?

["glenn-edgar@..." <glenn-edgar@...>]

I have used lua in various embedded environments, including embedded linux,
windriver, and ucos.  The environment is C.  The rom space averages around
100K and I use a standalone heap for lua.  The size of the stand alone heap
I have used is around 100K.  Useful work can be done with this size of
heap.  May have to manually envoke garbage collector in applications.

Still in many embedded enviroments a 100K of RAM is not available due to
power and cost reasons. I am working on constructs where useful stuff could
be done with a 32K or 16K heap.

Bottom line Lua can run in a very small environment.
