How to apply conditional outlining

I want to apply outlining for multiline comments - but ONLY if they do in fact span multiple lines.

I am using a dynamic language with code behind.
It works great if I open a file that already contains a multi-line comment, or paste a complete comment into the text.

However if I type a comment in normal fashion it does not display the outline unless I go back and change something on the line where the comment starts. [causing it to reparse that line]

I understand why that happens - I only set the start of an outline block if there is a matching 'end' AND it is on a different line.
Obviously that is not true when the start of the comment is typed.

I thought I could fix that by calling PerformAutomaticOutlining() for the TextRange of the '/*' [start comment] when the '*/' triggers the end outlining. However if I do that unconditionally it goes into a loop [expected].

I tried to call it conditionally based on SelectedView.DisplayLines(lineIdx).OutliningState but it seems that the Outlining State is always None.

Is this a bug, or do dynamic languages not set OutliningState?

Is there any other way to make this work?

Hi Mike,

To properly support this, you might not be able to use that basic DynamicOutliningSyntaxLanguage outlining functionality and might have to switch to the lower-level CollapsibleNodeOutliningParser as described in the "Automatic Outlining" topic.  Check that info out.

I would expect any kind of outlining to update the display line's outlining state since I think that is what it uses to render the box and line glyphs in the renderer.
