이것은 Xtext를 사용하여 DSL을 구현하기 위해 작성한 문법입니다.Xtext와 Xtend를 사용하여 코드를 생성하는 방법은 무엇입니까?

프로그래밍 언어 "Processing"및 현재 Xtext를 사용하여 언어에 대한 코드 제안을 작성하는 중입니다.
void setup(){
size(200,200);
}
void draw(){
ellipse(50,50,80,80);
}
는 지금은 아래에 언급 한 바와 같이 내 "test.pde"파일에 따라 "SRC 세대/test.java"파일을 생성 할 그것은 사전 컴파일러 코드 역할을합니다.
import processing.core.*;
public class Test extends PApplet {
public void setup(){
size(200,200);
}
public void draw(){
ellipse(50,50,80,80);
}
static public void main(String args[]) {
PApplet.main(new String[] { "--bgcolor=#ECE9D8", "a" });
}
}
누군가 나를 도와 주실 수 있습니까?
미리 감사드립니다.
어떤 Xtext 프레임 워크를 사용하고 있습니까? 1.x 또는 2.x? – Timotei
xtext 2.x입니다. – har
