It seemed like we got a lot of "This is<br />really good stuff", but I was looking for a little more of "show me<br />what you have done or are doing". But hey, I did learn about using let<br />for defining functions in ghci. That was good news. I had been always<br />loading functions from files.<br /><br />I took a class on Programming Language Principles at Sac State where we<br />used SML to define the grammar, do static analysis, dynamic analysis,<br />and finally evaluate the program. The starting point for this was that we<br />manually derived the program in Bauchus Naur Form. SML is a functional<br />programming language and in the end, we could see the power of SML. Yet,<br />I have been eager to continue doing work in this area.<br /><br />Here are few tools/resources I am excited abo
ut and
I would like to<br />share.<br /><br />1. Most languages are constructed using a Context Free Grammar (CFG)<br /> and ANTLR works has a graphical interface for laying out your rules. <br /> It will construct the lexer and parser code too,<br /> but beyond that, I don't think Java is the right tool. <br /> <a href="http://www.antlr.org/download/antlrworks-1.4.2.jar">http://www.antlr.org/download/antlrworks-1.4.2.jar</a><br /> <a href="http://www.antlr.org">http://www.antlr.org</a>/ <br /><br />2. I got a hold of Dan Friedman's book <br /> "Essentials of Programming Languages". It uses Scheme and one<br /> can use Dr. Racket (<a href="http://racket-lang.org">http://racket-lang.org</a>/) that has a<br /> EOPL (abbreviation for the book) mode.<br /><br />3. I found that my thinking recursively could be improved, so I also<br /> got Dan Friedman's book titled "The Little Schemer". It has<br /> a lot of practical examples that I think really help look <br /> a
t
things recursively, as seems to be essential in writing<br /> a language.<br /><br />Hopefully someday, I will have a language of my own. ;-)<br /><br />brian<br />-- <br />Brian Lavender<br /><a href="http://www.brie.com/brian">http://www.brie.com/brian</a>/<br /><br />"There are two ways of constructing a software design.
