[Acceleo] file-exists/ generate once [message #1095762]

Hi.

Im am facing a problem. I tried to search the forums and via google but I did not get any information on it.

I have a file I want to only generate if it does not exist. If the user decides to manipulate it the changes should be kept. On normal files and codes I would simply use [protected.... but there is no way to do this on the mentioned file. It is an xml and as soon as I embedd the xml in a user code with "<!-- [protected..." the editor silently removes the comment and acceleo recreates the whole file.

To solve the issue I wrote a query and a java service (fileExists(String) : Boolean).

All I want to know is: How to I get the target generation folder within the java service? The code is running at eclipse main folder. The current working dir is not set to the generation root.

Or is there any other way to solve this request?

Greetings

If you use an UI launcher plugin, the target folder is easily accessible. I had a similar problem a couple of day ago, I needed to change the target folder path wrt a persistent property value (refer to my old post http://www.eclipse.org/forums/index.php/t/512935/).

Concerning XML and protected block, I don't have any solution.

thanks. It is fine to me for generating the problematic xml file only once. However: For normal xml files you could simply use the protected code and embedd it into xml comments. Wink

Hmmm. It would be finde for me if this only works as eclipse plugin and not standalone. For testing the generator run it is not important if it overwrites the file.

Thanks for your hint.
