java-template

A simple and more readable tool generate Java Source code

Usage

1. #insert. String can be inserted in this

#insert imports_line;

2. #comment. Comment will be ignroed all together.

#comment this is just comment. 
#comment this lines will not be available in our resulted source code

3. ##VARIABLE##. All variables in the current template file will be replaced, except repeat block. Every variable name starts with ## and ends with ##

#comment example
String fileName = "##FILE_NAME##";

4. #import. Can be imported multiple time. After improting variables can be updated.

#comment example
#import resource_path

5. import_once. Can bee imported only once. Variables can be updated after improting.

#comment example
#import_once resource_path

6. Code block that can be injected more than once. Code block start with #start followed by a name. Block will be end with #end followed by the exact same name. Can be loaded only once.

#comment example
int i;
#start file_process_block
  i = ##VALUE_TO_SET##;
  fileOpen(##FILE_NAME##, ##VALUE_TO_SET##);
#end file_process_block

Example

1. template file

// main.template
package ##package_name##;
#import_once imports

public class ##class_name## {
    public static void main(String []args) {
        List<String> strs = new ArrayList<String>();
        #start value_set
        strs.add("##string##");
        #end value_set
        for(String s: strs) {
            System.out.print(s);
        }
        System.out.println("##final_message##");
    }
}

2. imports.template

import java.util.List;
import java.util.ArrayList;

3. Processing the block

import org.junit.jupiter.api.Test;

public class SimpleExampleTest {
    @Test
    public void execute() {
        TemplateProcessor tp = new TemplateProcessor(this.getClass(), "main");
        tp.setValue("package_name", "hello.world");
        tp.setValue("class_name", "HelloWorld");
        tp.setValue("final_message", "");
        tp.addImportBlock("imports");
        tp.addRepeatBlock("value_set", "n1").setValue("string", "Hello");
        tp.addRepeatBlock("value_set", "n2").setValue("string", " World");
        System.out.println(tp.toString());
    }
}

4. Generated Code

package hello.world;

// Importing imports
import java.util.List;
import java.util.ArrayList;

public class HelloWorld {
    public static void main(String []args) {
        List<String> strs = new ArrayList<String>();
        // Repeat block: value_set starts
        strs.add("Hello");
        strs.add(" World");
        // Repeat block: value_set ends
        for(String s: strs) {
            System.out.print(s);
        }
        System.out.println("");
    }
}
