Outline view contents disappear after adding code to sketch

[Ferreira31]

Describe the problem

I'm using the "Outline" view. The functions of the sketch are shown in the view when it is first opened, but when I edit the sketch the program outline disappears and is replaced with the message:

No outline information available.

To reproduce

The fault seems to be reproduced consistently by this procedure:

1. Select File > New from the Arduino IDE menus.
2. Press Ctrl+Shift+P to open the command palette
3. Select "Toggle Outline View".
4. Place the cursor at line 3
   You should now see the correct outline of the program.
5. Press Enter three times.
   The "OUTLINE" panel now shows "No outline information available".

Expected behavior

Program outline is updated in the "Outline" view as the sketch code is edited.

Arduino IDE version

2.0.0-beta.12-snapshot.4d8a7b8

Operating system

Windows

Operating system version

10

Additional context

The fault also occurs under conditions than the ones described in the reproduction instructions above.

---

I also encounter spurious results where outline components are missing or duplicated.

Output of Google Translate:

In Outline I've seen that appears the Loop function and void function, but now this bug, when I start, it is there, when I write anything goes away, I don't know how far this idea of putting the function tree goes, but already implemented, it would be nice if really were all functions, voids / if / while and etc, the functions that close code, and come description after it depending on the comment that is in the code.
And that it is possible to minimize the trees by functions and etc.
Besides that it is possible to minimize them in code, for example, I don't want to see the setup function now, minimize it, and that's it.

So for example, in the tree, this code below would look like this:

void setup
void test (Description 1)
------- if (If test)
void test2 (Description 2)
------- if (test2)
void loop

Right, is this

I am able to reproduce this issue simply by adding three line breaks to a sketch. For example:

1. Select File > New from the Arduino IDE menus.
2. Press Ctrl+Shift+P to open the command palette
3. Select "Toggle Outline View".
4. Place the cursor at line 3
   You should now see the correct outline of the program.
5. Press Enter three times.
   The "OUTLINE" panel now shows "No outline information available".

I have encountered it under other conditions as well, but this was a minimal demonstration that seems to work consistently.

I also see some spurious results where outline components are missing or duplicated.

The bug was reported 2 years ago, will this be fixed anytime? Or is this intended?

Still present in 2.00 beta.

At the moment it became worse: now the outline information is gone totally on 2.1.0, see issue #2087
