Auto format configuration doesn't match classic Arduino IDE

[ubidefeo]

Describe the bug
The auto format configuration used by the Java IDE represents a de facto Arduino code style that has been established and consistent for years.
The configuration is defined here:
https://github.com/arduino/Arduino/blob/1.8.13/build/shared/lib/formatter.conf
The documentation is here:
http://astyle.sourceforge.net/astyle.html
I personally find it disturbing when running an auto format on a sketch based on an official sketch or documentation snippet results in formatting changes to the existing code and I'm sure this could cause confusion for beginners. My experience indicates that changing the formatting of the official sketches and documentation snippets may be extremely difficult politically.
So I think it's very important to have continuity in the formatting configuration between the two IDE. If we do make changes to the official code style, the change should be based on a conscious decision, rather than just an arbitrary change.
This is the sort of thing that becomes more problematic to change as time goes on.

+1 this. It's the feature I use most when teaching. Until it's available I can't use the 2.0 IDE in class.

@tigoe
there's a patch in the works.
should be in the next beta which is not far from completion :)

Update, still does not appear to work in beta 6.

hi @tigoe

we're back on this issue, which board have you selected?
we know that because it requires some pre-compilation it can be slower on mbed based boards,
but it is working if you have a board selected

Weird, why does autoformat depend on the board type? I've been using the nano 33iot, the mkr 1010, the Uno, and the nano 33ble with the new ide. Autoformat not working on any of them.

Update, using 2.0.0-beta.11:

Auto format still not working.

test:

• make new sketch
• write blink code, without tabbing any lines
• press cmd-T
• Nothing happens

Update, using 2.0.0-beta.12:

Auto format still not working.

test:

• cmd-N
• write blink code, without tabbing any lines
• press cmd-T
• Nothing happens

re: other issues which mention this, auto-format should follow the standards set by the Java IDE, IMO, for things like braces, etc.
