IDE 2.0.0-rc2 Autoformat

Still doesn't work (doesn't do anything).

Which board do you have selected in the Arduino IDE's Board menu?

Please provide a sample of unformatted code that you would expect to exhibit a change after doing an Auto Format.

Arduino Uno.

After downloading 2.2.0-rc2, loaded a sketch and tried auto-format as it hadn't been functional in previous Beta releases. Simply backspaced an indent of a statement following a "while()", typed ctrl-T and nothing happened (repeatedly). After receiving your reply, tried it with another sketch and it worked albeit slowly (took several seconds to do it). Reloaded the original sketch and and it too worked (slowly) so I don't know what was going on.

Thanks, will let you know if it happens again...

The reason for the slowness is because the auto formatting is handled by Arduino Language Server. The language server reprocesses the sketch, including the Arduino core and any other libraries it uses after every change. The IDE shows an indicator of this on the status bar at the bottom left corner:

So the auto format is delayed when that processing is ongoing.

Happening again. This time error messages show up:

"Unable to watch for changes in this large workspace. Please follow the instructions link to resolve this issue".

The "Instructions" box links to a Visual Studio web page explaining the cause of the error.

The spurious "Unable to watch for changes in this large workspace" notifications are tracked here:

conclusion: resolved topic: code type: imperfection criticality: high

I occasionally get this warning from a new, bare minimum sketch: ``` Unable to… watch for file changes in this large workspace. Please follow the instructions link to resolve this issue. ``` ![Clipboard01](https://user-images.githubusercontent.com/8572152/109571950-4459ef00-7aa1-11eb-97eb-28377f2a1351.png) There doesn't seem to be any pattern to when I get it. I have a nearly empty sketchbook with only one library installed. The linked instructions are certainly nothing a beginner would enjoy being exposed to: https://code.visualstudio.com/docs/setup/linux#_visual-studio-code-is-unable-to-watch-for-file-changes-in-this-large-workspace-error-enospc It seems like this is a spurious warning and not a good user experience, especially for a beginner who won’t understand how to interpret it and may treat it as a “red herring” for completely unrelated problems they are having ([example](https://github.com/arduino/arduino-ide/issues/151)). ### Arduino IDE version #### Original report Unknown #### Last verified with ```text Version: 2.0.0-rc5-snapshot-b069f94 Date: 2022-04-05T09:31:01.231Z CLI Version: 0.21.0 [10107d24] ``` ### Operating system Windows ### Operating system version 10 ### Additional context [ originally reported by @per1234 ]

This is apparently a bug in the Eclipse Theia IDE framework used by the Arduino IDE 2.x

I don't know what the conditions are that cause this spurious "Unable to watch for changes in this large workspace" notification, so my ability to investigate the impacts is limited.

However, I did just happen to get one of these notifications. Auto Format continued to work as expected. So there is not a universal correlation between that notification and the auto format not working bug (arduino/arduino-ide#396, arduino/arduino-ide#337)
