Formatting comments [message #1700394]

I was wondering if there is a way to read the document line by line and replace the lines with comments to give them proper indentation.
Is this possible? :
-Read document line by line
-Replace selected parts

Using the old formatting API.

I think you can achieve that by adding your own replacer (extending CommentReplacer maybe ?) to that Comment Region.
But you are not using Formatter2 right ?

I am not using formatter2. I am experiencing some problems with it as it doesn't automatically onewhitespace format my document which is something I need. And for example I want to insert a new line after each ';' I don't know how to do that globally without modifying each element's format function. My dsl is big.

"I am experiencing some problems with it as it doesn't automatically onewhitespace format my document which is something I need"

I am pretty sure it is possible to achieve that !
Like getting rid of the dispatch method strategy and instead you go through the AST and call the same formatting method on each EObject.
I did something like that for a graph view of a DSL document:

val ti = EcoreUtil.getAllProperContents(resource, false)

protected void doFormat(final Iterator<EObject> ti) {
		while (ti.hasNext()) {
			       EObject eobject = ti.next();
				//TODO: oneSpaceFormat(eobject,document);
				TreeIterator<EObject> subti = eobject.eAllContents();
				EList<EObject> subli = eobject.eCrossReferences();

				if (subti.hasNext()) {
					doFormat(subti);
				}
				if (subli.size() > 0) {
					doFormat(subli.iterator());
				}
		}
	}

I just cleaned and reused code, but I guess it could work like that ?

oneSpaceFormat(eobject,document); Would format each type of eobject specifically?

No, it would be one method for all.
Its implementation would be very simple, just something like that as a start:

eobject.append[oneSpace]

Sorry I just realized the doFormat code is useless in that case because you can just use the format(EObject eobject, Document doc) method
from the abstractformatter and do your oneSpace formatting. So, very simple.
Stupid from me, sorry again !
