Feature Request: cmd line

[polluks]

How about officially supporting ProDOS 2.5 command line parameters in cc65?

I have some command line parsing code which works in sortdir.c. It is conditionally compiled out at the moment because it is only useful for programs which are small enough to load from BASIC.SYSTEM (ie: fit from 0x2000 to 0x9600 if it is a SYSTEM file). However you can swipe the code if you like, or we can re-do it in ASM if that is better for cc65.

#define MAXNUMARGS 10

int argc;
char *argv[MAXNUMARGS];

void parseargs() {
    char *p;
    char i = 0, s = 0, prev = ' ';
    argc = 1;
    for (p = (char*)0x200; p <= (char*)0x27f; ++p) {
        *p &= 0x7f;
        if ((*p == 0) || (*p == 0x0d)) {
            argv[argc - 1] = buf + s;
            break;
        }
        if (*p == ' ') {
            if (prev != ' ') {
                buf[i++] = '\0';
                argv[argc - 1] = buf + s;
                s = i;
                ++argc;
            }
        } else {
            buf[i++] = *p;
        }
        prev = *p;
    }
}

#endif

@bobbimanners Thanks, I think we have to wait for the release of 2.5.
