More functions

[toncho11]

We need to either port some Lua libraries or implement some functions directly into the base.

Here is a initial list of functions that are good to have on ELKS:

• sleep()
• press_any_key()
• read key https://stackoverflow.com/questions/17958309/is-there-a-get-keyboard-input-function-in-lua-arrow-keys
• ctrl+c signal handling

[toncho11]

So the ctrl+c should be something like that:

local function main()
    while true do
        print("Running... Press Ctrl+C to stop.")
        os.execute("sleep 1")  -- Simulate work
    end
end

local success, err = pcall(main)

if not success then
    print("Interrupted! Exiting gracefully.")
end

@ghaerr What is the recommended way to perform millisecond sleep of 40 ms for example?
libc/system/usleep.c ? So it should be:

#include <unistd.h>
usleep(40000);

for example?

[ghaerr]

Yes, that's correct @toncho11.

How about wrapping some curses functions just like these ones:

[rafael2k]

I think we should move all these functions to loslib, as it is an os-dependent function in lua definition.

[toncho11]

Yes, that's correct @toncho11.

Thanks. I see you used also:

void GdDelay(unsigned long msecs)
{
    struct timeval timeval;

    timeval.tv_sec = msecs / 1000;
    timeval.tv_usec = (msecs % 1000) * 1000;
    select(0, NULL, NULL, NULL, &timeval);
}

@toncho11, I'm not sure about which recent changes in drawcube.lua did this, but it is running out-of-memory after running some time. I feel some kind of memory leak in the new version.
