[rules-dev] Long DSL lines

Currently each entry must be a single line of text. This results in long lines, especially on the RHS. I have experimentally inserted a transformation of the DSL text (in DSLTokenizedMappingFile) which converts '\'+EOL on the fly to a space. (The passed-in reader is read into a buffer, '\'+EOL is translated to space, and EOLs are inserted later to readjust the line number.) In a text editor, I can now write, e.g., then][][Bb]ook the customer for the flight=\ $f.setAvailable( $f.getAvailable() - 1 );\ update( $f ); \ Booking booking = new Booking(); \ booking.setCustomer( $r.getCustomer() ); \ booking.setFlight( $f ); \ insert( booking ); Of course, the DSL editor will not preserve this, but future development might provide more convenient editing there, too. Any objections? -W
