Hi,

I am trying to generate files using EGL/EGX.
I'd like the datetime to be included in the file names every time I run the transformation.
I used the following codes, but it didn't work.
Could anyone help me fix this?

pre{
 var javaDate = new Native("java.util.Date");
 var javaDateString = new String;
 javaDateString= javaDate.toString();
}
rule AC2Diagram {
  template : "GSN_AC_R1.egl"
  target : "GSN_AC_R1_"+javaDateString+".dot"
}

Thanks
Fang

Hi Fang,

Could you please explain what you mean by "it didn't work"? Are you getting a runtime exception, is the date just not in the format you'd like, something else?

Best,
Dimitris

Hi Dimitris,

I just found out that I got an exception because the format is illegal as shown in the image attached.

How could I change the format to remove all the spaces, etc.?

Thanks
Fang

Hi Fang,

The following should do the trick.

new Native("java.text.SimpleDateFormat")("dd-MM-yyyy").
  format(new Native("java.util.Date")).println();

Best,
Dimitris
