- code cleanup
- the platform is now named 'sim'. You build it like this:
$ scons cpu=linux
The idea is to support more than one host OS by changing the "cpu" variable
above (for example cpu=osx, or cpu=win32). Also, a crude "host interface" was
defined in hostif.h. In theory, a host OS should only implement that interface
in order to run the eLua simulator. The implementation must reside in a file
called hostif_{os}.c (in this case hostif_linux.c). Too bad I don't have a MAC,
I would've loved to try this :)
REMEMBER: whem implementing a host interface, you CAN NOT rely on your regular
libc! You'll have to rewrite the syscalls (see host.c for an example on how to
do this in Linux).
- after you build it, don't start it directly, use the new "run_elua_sim.sh"
script to run it. It will set the terminal to raw mode, no echo, so it will
behave more like "traditional" eLua (even hangman.lua will run in this mode :) ).
Remember to run in on an ANSI capable terminal (although most of them support
ANSI emulation nowadays).
- you can exit from the simulator with "exit". You can't do this with CTRL+C if
you run it with "run_elua_sim.sh".
All in all, this looks pretty good and it's an excellent test platform. It will
do wonders when we integrate our own libc and we won't be able to figure out why
it doesn't work :)
