In my current project I'm using deferred binding to generate code. The code
generation is heavily based on writer.write(String), writer.indent() and
writer.outdent():
writer.write("%s = new %s<%s>();", var1, collectionImplementation, paramType
);
writer.write("for (Element %s : %s) {", elementVariable, elementsVariable);
writer.indent();
writer.write("if (%s != null) {", valueVariable);
writer.indent();
writer.write("%s.add(%s);", valueVariable, valueVariable);
writer.outdent();
writer.write("}");
writer.outdent();
writer.write("}");
The whole process became very complex and error-prone. I'm thinking about to
use velocity templates. Has anyone already used velocity templates for
code generation? Is this a good idea? What do you think?
