5. Linux port.
I don't pay as much attention to Linux version of this software, however
I try my best to make the program work correctly on Linux and behave in the
same manner on both Windows and Linux platforms.
The most challenging part surprisingly was implementation of the character
I/O emulation on Linux. Easy on Windows with its conio.h header and kbhit()
and getch() functions that provide non-blocking keyboard input, Linux part
required some research and implementing some known programming tricks to get
this to work. I got it working but then lost touch with Linux version for
a while. After I added graphics device and SDL2 library, I worked on Linux
port to have these features working on Linux platform as well. To my surprise
I discovered then that my implementation of character I/O (the non-blocking
character input) stopped working. After many failed attempts and research
I decided to rewrite the Linux character I/O part using ncurses library.
This works although has its own problems. E.g.: ncurses getch() returns NL
character (0x0A) when ENTER is pressed, while Windows conio equivalent returns
CR (0x0D) and this is the code that 6502 programs, like Tiny Basic or EhBasic
expect. Backspace also wasn't working. I enabled function keys during ncurses
initialization and intercept backspace code for later conversion. This
solved it, but there may be more issues discovered later which I didn't fully
test.
unsigned char MemMapDev::ReadCharKb(bool nonblock)
{
[...]
#if defined(LINUX)
if (c == 3) { // capture CTRL-C in CONIO mode
mpConsoleIO->CloseCursesScr();
kill(getpid(),SIGINT);
} else if (c == 0x0A) {
c = 0x0D; // without this conversion EhBasic won't work
} else if (c == KEY_BACKSPACE) {
c = 8; // raw/cbreak modes do not pass the backspace
}
#endif
[...]
Another issue was that when 6502 code sends CR/LF sequence, the CR code
moves the cursor to the beginning of the line before applying NL (new line)
and clears the characters on its path! Therefore I'd have the text removed
from the screen (although my internal display device emulation in Display
class has its own buffer and all characters were there, it was only a visual
side effect). Therefore I have to convert CR/LF sequences to LF/CR.
Also because of the way I output characters to nsurses screen, control
characters don't work and must be intercepted and properly converted to
appropriate action. Example - the bell (audible) code 7:
void MemMapDev::PutCharIO(char c)
{
mCharIOBufOut[mOutBufDataEnd] = c;
mOutBufDataEnd++;
if (mOutBufDataEnd >= CHARIO_BUF_SIZE) mOutBufDataEnd = 0;
if (mCharIOActive) {
#if defined(LINUX)
// because ncurses will remove characters if sequence is
// CR,NL, I convert CR,NL to NL,CR (NL=0x0A, CR=0x0D)
static char prevc = 0;
if (c == 7) mpConsoleIO->Beep();
else
if (c == 0x0D && prevc != 0x0A) { prevc = c; c = 0x0A; }
else if (c == 0x0A && prevc == 0x0D) {
prevc = c; c = 0x0D;
mpConsoleIO->PrintChar(prevc);
mpConsoleIO->PrintChar(c);
}
else { prevc = c; mpConsoleIO->PrintChar(c); }
#else
mpConsoleIO->PrintChar(c);
#endif
CharIOFlush();
}
}
