Re: More formulotic thought

[Glen Stampoultzis]

Funny you should mention this. I'm working on a little open source project at the moment that is using antlr. Works great and is well documented. I didn't find coming up with a grammer hard at all. This is a big boys parser though. There is a learning curve involved. I'm using it in a simpler mode just to build an AST. When you get to tree walkers I start getting a little more confused.

One really cool thing I like about it is that the code is generates is actually pretty easy to read. Quite close to what you might write if you were going it by hand.

Hi All especially Avik,

Have you seen this: (http://www.jguru.com/faq/view.jsp?EID=78)? At one time we
were thinking about doing the formula parser with a tool like this, but never did because
they all had crummy licenses which required the user to do things that we thought they ought not
have to do. This sucker is in the public domain under a "do whatever the hell you want" license.

Downside: Debugability will be lower, writing the grammer will be a bitch
Upside: We might actually finish formulas this year ;-)

Take a read of that.. I'm not exactly sure that it can or can't go the other direction (Binary->Text)
