Bug with "Peek Declaration" and "Peek Definition" also with "Go To ..."

[sstaub]

Describe the bug
There is a bug with "Peek Declaration" and "Peek Definition"
"Peek Declaration" does nothing!
"Peek Definition" shoes the declaration of functions instead of their definition
The same happens with "Go To...

To Reproduce
Steps to reproduce the behavior:

1. Open Blink example
2. right click on digitalWrite and select "Peek Declaration" -> noting happens
3. right click on digitalWrite and select "Peek declaration" -> it shows the declaration in common.h

Expected behavior
It should work like in VSC, in this example

• "Peek Declaration" should show the declaration of the function in common.h
• "Peek Definition" should show the definition of the function in wiring_digital.c

Screenshots

• Peek Definition in Arduino IDE

• Peek Definition in VSC

Desktop (please complete the following information):

• macOS Catalina
• Version 0.0.1

"Peek Declaration" does nothing!

This non-functional feature has been removed.

right click on digitalWrite and select "Peek declaration" -> it shows the declaration in common.h

This issue is board-specific. For example, I am able to reproduce it with the "Arduino MKRZERO" board, but not with "Arduino Uno".

Note that the megaavr architecture is not supported at all now (#31), so you will no longer get the described results with the "Arduino Nano Every" board selected.

As I mentioned above, the non-functional "Peek Declaration" feature was removed (#1394). We are tracking the need to implement this feature at arduino/arduino-language-server#156.

This leaves one other bug report that was mashed into this issue:

"Peek Definition" shoes the declaration of functions instead of their definition
The same happens with "Go To...

We are now tracking that in the higher quality issue arduino/arduino-language-server#167 so I will close this one as a duplicate.
