adding new markers to edit session

[alon]

hello,
im trying to hook up a few markers in real-time to show users
position on the current edit session.
basic collaboration showing where the users are currently marked in
the text.

I managed to get the cursor position, line and char but i cant seem to
add custom markers to annotations to the code myself.

Can someone provide me with some info about it?

this is what i did so far

editorsession.setAnnotations([{
row: editorcursor.row,
column: editorcursor.column,
text: "Strange error",
type: "info"
}]);

var markerId = editorsession.renderer.addMarker(new Range(1, 10, 1,
15),
"warning", "text");
editorsession.addMarker(range, "ace_bracketx");

nothing shows up.

This should work. The same way I do the jslint annotations.

The second argument is the CSS class used for the marker. You need to
define the styles yourself. This is e.g. how the selection is styled:

.ace_marker-layer .ace_selection {
position: absolute;
z-index: 4;
background: rgb(181, 213, 255);\
}

in your case the CSS selector would be ".ace_marker-layer warning".

Instead of the CSS class you can also pass a function which generates
the marker's markup as second argument. This way you can have the
marker anyway you like. In this case you will have to read
lib/ace/layer/marker.js to understand how it works.

Best,
