--console-only launches mmbasic_ansi with a console only terminal, no graphics.  Any graphics programs will just appear to hang at the console until the program exits. The editor works just fine, and the environment responds to terminal resizes.

I think I addressed the control-Z issue, let me know.

Just re-download it.


libc problems fixed, it now runs happily under linux mint 19.3 and using the --console-only parameter produces usable output.

but while ctrl-Z is fixed, both ctrl-C and ctrl-D are not handled and terminate mmbasic. the problems with ctrl-C and -D, as well as the original with ctrl-Z can all be fixed by placing the terminal in RAW mode. the following pascal (FPC) code does this, taken from a serial-over-TCP/IP VT102 emulation hack i wrote a few years back:

program talkto;

uses sysutils, termIO, BaseUnix;

var tios, SAVEDtios:termios;

begin
  TCGetAttr(0, tios);
  SAVEDtios:=tios;
  CFMakeRaw(tios);
  TCSetAttr(0, TCSANOW, tios);                 // place console in RAW mode

  repeat                                       // main loop, use break to exit  
  until false;

  TCSetAttr(0, TCSANOW, SAVEDtios)             // restore console state
end.


hopefully converting this into C should be simple!


btw, option list seems to not work. i tested by setting and resetting option colourcode on/off where option list produced no output no matter what the setting was.

if desired, you could make options persistent by saving them in a .ini file of the same name and location as the mmbasic binary. this .ini file could then also hold settings such as --console-only. but this is all just a suggestion!


cheers,

Thanks for the feedback. These should now be fixed.
