The question why this doesn't work can be simplified to the question why
bool matches =
parse ("1.0,2.0,3.0,4.0\n5.0,6.0,7.0,8.0",
real_p >> *(',' >> real_p)
, space_p).full;
will result in matches being "false".
I think the reason is that the skip parser "space_p" will eat the "\n" between "4.0" and "5.0", but it will not insert a ','. A potential solution might be to make ',' optional by writing !',':
bool matches =
parse ("1.0,2.0,3.0,4.0\n5.0,6.0,7.0,8.0",
real_p >> *(!',' >> real_p)
, space_p).full;
will probably result in matches being "true".
