Hey Perl fans,
What's your favorite regular expression for a subpart line (or any other
line, for that matter) in an LDraw DAT file?
Here's my entry; $linein is a single line from the DAT file, may or may not
be padded with whitespace at the beginning or the end:
if( $linein =~ m/
^
\s*1 # indicates a subpart
\s+([0-9]+) # color
(?:\s+[0-9]+){3} # coordinates
(?:\s+[0-9]+){9} # 3 x 3 transform matrix
\s+(\S+) # part name
\s*$
/x ) {
# $1 = color
# $2 = subpart name
# etc...
}
Cheers,
- jsproat

| (...) Whoops! I need to account for floating point values within the matrix. m/ ^ \s*1 # indicates a subpart \s+([0-9]+) # color (?:\s+[+-]?[0-9]+(?:...-9]+)?){3} # coordinates (?:\s+[+-]?[0-9]+(?:...-9]+)?){9} # 3 x 3 transform matrix \s+(\S+) # (...)
