[Xpand] Dynamic position of generated text [message #843658]

Hi all,

Please take a look at my problem. Let's consider that we have 3 very simple templates in Xpand: class, variable and method.

«DEFINE class FOR X»
public class MyClass {
	«EXPAND variableDec»
	«EXPAND method»
}
«ENDDEFINE»

«DEFINE variable FOR X»
	int a = 0;
	int b = 0;
	int c = 0;
«ENDDEFINE»

«DEFINE method FOR X»
	public static String methodA() {
		«EXPAND variable»
	}
«ENDDEFINE»

The output shall be:

public class MyClass {
	int a = 0;
	int b = 0;
	int c = 0;
	
	public static String methodA() {
	int a = 0;
	int b = 0;
	int c = 0;
	}
}

So I wonder that do we have any way to make the text generated right at the place where EXPAND statement is placed. Specifically, if we update the template variable as:

«DEFINE variable FOR X»
int a = 0;
int b = 0;
int c = 0;
«ENDDEFINE»

And the calling of variable template in other templates:

«DEFINE class FOR X»
public class MyClass {
	«EXPAND variableDec»
	«EXPAND method»
}
«ENDDEFINE»

«DEFINE method FOR X»
public static String methodA() {
	«EXPAND variable»
}
«ENDDEFINE»

Then the expected text is generated as:

public class MyClass {
	int a = 0;
	int b = 0;
	int c = 0;
	
	public static String methodA() {
		int a = 0;
		int b = 0;
		int c = 0;
	}
}

Hope that everyone could understand my situation. Thanks for any help!

Hi Christian,

Of course it is always working. The point here is that I have a "common" template just like the above sample:

«DEFINE variable FOR X»
	int a = 0;
	int b = 0;
	int c = 0;
«ENDDEFINE»

This template shall be called from the others such as:

«DEFINE class FOR X»
public class MyClass {
	«EXPAND variable»	
}
«ENDDEFINE»

--> The output here is OK:

public class MyClass {
	int a = 0;
	int b = 0;
	int c = 0;	
}

However, due to this template is common, so there is another usecase like this:

«DEFINE class FOR X»
public class MyClass {
	
	public static String methodA() {
		«EXPAND variable»
	}
}
«ENDDEFINE»

The code is actually generated as:

public class MyClass {
	
	public static String methodA() {
	int a = 0;
	int b = 0;
	int c = 0;
	}
}

But expected as:

public class MyClass {
	int a = 0;
	int b = 0;
	int c = 0;
	
	public static String methodA() {
		int a = 0;
		int b = 0;
		int c = 0;
	}
}

How do you think?

Still confusing what you mean. Are you talking about the indention?

Yes, that is it. About the indention.
How to dynamically change it?

I already got a beautifer (to remove some empty lines, replace some characters...), but could you please be more precise on this usecase?
