[EGL] Append output to existing file [message #1272615]

Hi,
I would like to run the same M2T transformation several times, with different inputs, and append the output to the same file.
Here is an example snippet from an EGL file:

	var f = new Native("org.eclipse.epsilon.egl.formatter.language.JavaFormatter");
	TemplateFactory.setDefaultFormatter(f);
	for(binding in Binding.all) {
		var template:Template = TemplateFactory.load("binding.egl");
		template.populate("binding",binding);
		template.generate("generated/out.txt");
	}

The out.txt file will be overwritten each time, is there an option to only append to file?

I considered using

template.process()

to get a string of the generated content and append to it, but could not find a way to write it to a file.

thanks for your help,
Esteban

Hi Esteban,

Instead of template.generate() you should be able to invoke template.append().

Cheers,

Hi,
using this code:

[%
	var f = new Native("org.eclipse.epsilon.egl.formatter.language.JavaFormatter");
	TemplateFactory.setDefaultFormatter(f);
	var template:Template = TemplateFactory.load("binding.egl");
	for(binding in Binding.all) {
		template.populate("binding",binding);
		template.append("generated/out.txt");
	}

%]

I get this error:

Method 'append' not found for: org.eclipse.epsilon.egl.EglFileGeneratingTemplate

I checked the javadoc here: http://download.eclipse.org/epsilon/javadoc/ and could not find this method.
I have everything from the interim update site (http://download.eclipse.org/epsilon/interim/) installed.

Cheers,
Esteban

Hi Esteban,

You're right - this hasn't made it to the interim update site yet. I plan to release a new interim version over the weekend but please let me know if this is a blocker and I'll try to do this sooner.

Cheers,
Dimitris
