Arg. Is this allowed? I guess it should be; the original parser was
implemented using Pascal...
Yes, ugly getting it is, hmmm? :-,
if( $linein =~ m/
^
\s*1
# indicates a subpart
\s+([0-9]+)
# color
(?:\s+[+-]?[0-9]+(?:\.[0-9]+)?(?:E[+-]?[0-9+])?){3}
# coordinates
(?:\s+[+-]?[0-9]+(?:\.[0-9]+)?(?:E[+-]?[0-9+])?){9}
# 3 x 3 matrix
\s+(\S+)
# part name
\s*$
/xi ) {
# $1 = color
# $2 = part
}
