I am an engineering student, and deciding upon my final year project.
One of the many candidates is an online UML tool with code generation facilities. But I did not take compiler designing classes, so I am not much aware of the code generation techniques.
I want to know about the techniques that I should look to study in order to build something like this. If these techniques are as complicated as writing a compiler, then perhaps I will have to abandon this idea.
Compilation is really the opposite of the kind of code generation you are describing, so I don’t think you need to know how to write a compiler.
Code generation can be as simple as combining text strings or using templates, or as complex as using Reflection.Emit to create classes at runtime.
I would start with this Wikipedia article.
