Should the formatter also add missing braces

[aozarov]

To correct any violation of https://google.github.io/styleguide/javaguide.html#s4.1.1-braces-always-used

Currently it looks like a code that is formatted like

if (condition)
  do_something

would be formatted (after running the tool) as:

if (condition) do_someting

where as I would expect it to be formatted as:

if (condition) {
  do_something
}

Yes, adding braces is a request we're considering (there are some concerns unique to making non-whitespace changes that we'd have to sort through).

In the meantime, the current behavior is acceptable, because (a) it's exactly what users following AOSP style want, and (b) for Google Style the code was already incorrect anyway, and maybe the odd change will prompt a human to make the right fix.

Any update on this? I keep having to resolve flame wars between those who want what the Google style guide says vs. what the tools actually enforce.

Will this be fixed anytime soon?

This feature would be really helpful. We have some legacy code where we have a lot of if conditions without braces. This makes it so error prone for a change. Just reformatting that code would improve readability and make it a bit friendly for changes.

Pasting comment from similar issue:

So far, GJF has been focused on being a formatter, which is a somewhat narrower purpose than "style correcter". It does nothing but insert and remove whitespace characters, and sometimes reorder things. The more general tool would be useful, but I don't think we plan for this to become that. If cushon replies, take his word over mine. :-)

(EDIT: I was reminded that it does have a few other non-whitespace changes it's willing to make, so I made this point a little too strongly.)
