I've tried and got bogged down. Porting to a DLL-based Win32 library was
relatively simple -- a matter of exporting the right functions and
variables. Moving it to Windows CE is non-trivial, however, for the
1) File operations all use UNIX-style high-level file I/O (fopen, etc.).
These functions aren't supported in the CRT supplied by Microsoft for CE.
Just cutting out these functions isn't a useful way to handle things
because error reporting is done using fprintf -- another unsupported
function in Windows CE.
2) The native string type of Lua seems to be "array of bytes". The native
string type in Windows CE is Unicode. This could present some problems
down the line.
I got about half-way through resolving problem 1 before I had to return to
stuff that pays my paycheque. I'll get back to working on it probably
sometime in January.
For the 3.2 release of Lua, I'd make these recommendations to the
1) Move as much of the I/O into contextual wrapper functions ("report
error" or "write to file") as possible (and maybe even more than what is
possible:-). I believe this is already being worked on.
2) Provide compiler switches to allow for wide-character compilation. It's
necessary if Lua is to be internationalized anyway.
I have volunteered in the past in this very forum to work with the
implementors on making Lua Win32-friendly, but have received no reply.
