Possibility to restrict "Show method parameter names" to primitives

I’d like to have a possiblity to restrict “Show method parameter names” in a way that the names are only displayed on primitives (boolean,int,long…) and strings.

I think mostly by passing complex objects one can derive their meaning from the type. Assume the following editor-view:

File dir = new File(pathname: "/tmp/test/");
doSomething(directory: dir, create: true);

The “directory:” parameter-name does not provide any useful additional information but uses a lot of space. With the suggested feature enabled it would look like:

File dir = new File(pathname: "/tmp/test/");
doSomething(dir, create: true);

@nuessgens @vogella please reinstall JDT CodeMining, now you have a new preference Show parameter only for literal which is enabled by default. Here a little demo:

I have enabled by default, because I agree with @gayanper comment https://github.com/angelozerr/jdt-codemining/issues/53#issuecomment-402507576

Thanks for your feedback @nuessgens
