Welcome to the CodeGen wiki!

CodeGen is a framework for generating code stubs from a model structure. If you have a lot of code that depends on the structure of a database, a file system or any other source of information, generate the code instead! It is completely object oriented to encourage reuse and increase testability.

Automated tasks

Consumers can be called on a model tree to perform automated tasks. This can be useful when automating documentation, making all parameters final, all member variables private, etc.

Different views

Models doesn't contain any logic more than is required to set it up. If you want to visualize the model, create a view! The same model can be used by different views to display the data in different ways. Maybe you want to generate xml-files as well as java-code from the same source?

Example

System.out.println(new JavaGenerator().on(
    File.of("org/example/BasicExample.java")
        .add(Class.of("BasicExample")
            .add(Default.GENERATED)
            .public_()
            .add(
                Field.of("BASIC_MESSAGE", Default.STRING)
                .public_().final_().static_()
                .setValue(new TextValue("Hello, world!"))
            )
            .add(
                Method.of("main", Default.VOID)
                .setJavadoc(Javadoc.of(
                    "This is a vary basic example of ",
                    "the capabilities of the Code Generator."
                ))
                .public_().static_()
                .add(Field.of("params", Default.STRING.setArrayDimension(1)))
                .add(
                    "System.out.println(BASIC_MESSAGE);"
                )
            )
        ).call(new AutoJavadoc())
    ).get()
);

Result

/**
 * Write some documentation here.
 */
package org.example;

public class BasicExample {
    public final static String BASIC_MESSAGE = "Hello, world!";
    
    /**
     * This is a vary basic example of 
     * the capabilities of the Code Generator.
     */
    public static void main(String[] params) {
        System.out.println(BASIC_MESSAGE);
    }
}

Languages

Currently only the java language is supported, but the language-dependent code is contained in a single package so that more languages can be supported in the future. Most of the java package can probably be reused if the language in question is similair in syntax.
