I personally didn't write any of our C# code, but a couple of our issues with .NET: - my biggest issue with .NET is that to get line numbers in stack traces you have to generate a pdb file - this is ugly from a deployment perspective if you want line numbers in production code. That format is Microsoft specific (I think Mono uses a different format). Worse of all is that you actually have to generate the pdb file on the disk which just kills performance. It is a lot of work compared to the elegance of adding a line table attribute in Java bytecode. - jars are simple pkzip files and easy to generate, I can't say the same about generating a dll from scratch - the JVM provides more flexibility to dynamically load types because there is an extremely clear specification to describe the binary classfile. Writing a simple bytecode assembler is a day of work - you can generate classes easily in memory and load them as needed on a class granularity basis. .NET imposes more restrictions about how bits and pieces of an assembly are dynamically loaded. Right now we ended up just generating the whole assembly at once to avoid the headaches, but that is a real performance issue we still need to address. - as a compiler writer I find the lack of stack manipulation bytecodes for a stack based VM frustrating because you need to resort to synthetic local variables - personally I find Microsoft's online documentation exceedingly difficult to work with (but that is just a matter of taste) I just really like Java's simple and extremely well specified file formats. But in the end they are both really great VMs. How do you handle line numbers in Boo? Are we just missing something, or do you really have to generate a pdb file to disk? --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "JVM Languages" group.
