The examples you provide with the source are excellent, and I really should have mentioned them in my post. They’re pretty much entirely how I learnt the syntax (and probably why I don’t know any more than is in them).

Error handling is my only real complaint with it, and even that isn’t such a problem once you figure out the generated code. I’m pretty adept at debugging the parsers now. Getting more helpful output would be good, it’d certainly ease the learning curve a bit. I attempted this myself while I was writing SharpDiff, but didn’t get very far. However, I might take another look next time I get some spare time.

Thanks again, I’ll probably take you up on that offer of help

I definitely need to improve the error handling. At the very least, report where the error is instead of the very unhelpful “something bad happened” default handler.

I must confess that I sometimes forget the commas too

I also must say that I’ve been making things up as I’ve gone along (especially with .net-ifying the syntax) and refactoring where I can. Note that you can say “LetterOrDigit+:name ‘.’ LetterOrDigit+:ext” and then you don’t have to use the .As’s. It’s a little bit terser until I can get smarter duck typing.

You’ve done a great job of explaining how things work. In the OMeta# release, you’ll see several toy projects that do something similar to your tests. For example, the “Calculator” example shows how to run automated tests as well as interactive console based sessions.

The Prolog one is my current favorite since it was the hardest to write.

Keep up the good work. Always feel free to contact me as you run into issues. And if you ever want to be a contributer to the project, OMeta# would be better for it

Cheers,

Jeff
