CodeGen

A model-view based code generator written in Java. It is completely object oriented to encourage reuse and increase testability. 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!

Download

To use CodeGen in your projects, add the following dependency to your pom.xml-file:

<dependency>
    <groupId>com.github.pyknic</groupId>
    <artifactId>codegen</artifactId>
    <version>2.4.5</version>
</dependency>

Example

System.out.println(new JavaGenerator().on(
    File.of("org/example/BasicExample.java")
        .add(Class.of("BasicExample")
            .add(GENERATED)
            .public_()
            .add(
                Field.of("BASIC_MESSAGE", String.class)
                .public_().final_().static_()
                .set(Value.ofText("Hello, world!"))
            )
            .add(
                Method.of("main", void.class)
                .set(Javadoc.of(
                    "This is a vary basic example of " +
                    "the capabilities of the Code Generator."
                ))
                .public_().static_()
                .add(Field.of("params", String[].class))
                .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.
