Excellent example of code generation from abstract syntax trees using Lex and Yacc

    http://www.epaperpress.com/lexandyacc/index.html


This is the most succinct example of code generation that I have ever
encountered. It includes an interpreter, a code generator, and
graphical output of the abstract syntax tree diagram. Because of this
one example I finally understand the best way to generate code.


I have struggled with obtaining this knowledge for twenty years
carefully studying the relevant chapters of the Dragon book. Now
finally with one succinct example, I got it. I want to make sure that
I share this information in a way that others can most easily reach
it.


I have recommended that this author's work be added to the Oreilly book, lex &
yacc, Second Edition By John Levine, Tony Mason, Doug Brown.
