Hi,
next helpless question: what Scheme type is the "location" argument used
for Scheme functions?
(write)ing location gives
Hi, its:
ly:input-location?
HTH
Unfortunately not (TH).
This is what redirects me to
Input *
unsmob_input (SCM s)
{
if (SCM_IMP (s))
return 0;
if (SCM_CAR (s) == (SCM)input_tag) // ugh.
return (Input *) SCM_CDR (s);
else
return 0;
}
And that's where I get stuck. This function looks like it somehow munges
a Scheme pair or list, so I tried to access it through
(car location)
but that didn't work. Which isn't surprising because the original
(write) would have printed something like (location "...") if it were a
list, isn't it?
