Hello Andrew, 

try this (header omitted, output at the end): 

--------------------------------------------------------------------- 
%tokens% 

colon = ':' 
equals = '=' 
lbracket = '[' 
rbracket = ']' 

string_literal = <<"[^"]*">> 
integer_literal = <<[0-9]+>> 
real_literal = <<-?[0-9]+\.[0-9]+>> 
identifier = <<[A-Z][A-Z0-9_]*>> 

whitespace = <<[ \t]+>> %ignore% 
newline = <<[\n\r]+>> 


%productions% 

start = line+ ; 
line = contents? newline ; 
contents = key '=' values? | values ; 
key = identifier ( ':' identifier )? ( '[' integer_literal ']' )? ; 
values = value+ ; 
value = string_literal | integer_literal | real_literal | identifier ;
--------------------------------------------------------------------- 

Feel free to come back with questions! 
Regards 
Oliver
