[OpenBIOS] Parsing empty \ comments

[Rolf Schroedter]

I noticed that kernel/bootstrap.c fails parsing empty \ comments, e.g.
from "bootstrap.fs":

\ Some comment<lf>
    <lf>
    : tuck  swap over ;

complaining about "tuck not defined". No problem if the 2nd line has a 
space:
    \ <lf>

One could say "That's FORTH", but IMHO this behavior is ugly because
the difference between both cases is not visible. In my case I had an 
editor
configured to truncate trailing spaces in a line ...

I suggest to resolve this problem by not eating <lf> when parsing
for white spaces(delim=0) in parse(f,line,delim ), something like:

static int parse(FILE * f, char *line, char delim)
{
    int cnt = 0, c;
    while (!feof(f)) {
    	c = getc(f);
    	if (delim && c == delim)
    		break;
    	if ((!delim) && (c == ' ' || c == '\n' || c == '\t')) {
> > > > > 	if (c == '\n') ungetc(c, f);

break;
    	}
    	line[cnt++] = c;
    }
    line[cnt] = 0;
    return cnt;
}

A similar change should probably be done at FORTH level in ": 
parse-word" and/or ": parse".
