It would be really nice to have the pretty printer be good enough to use it as a code formatter, ala gofmt. It still has some issues (I've been working on it), but it is reasonably close to being usable in that way.

But, the commandline invocation is kind of unwieldy (and feels redundant). It seems like --pretty should just pretty print, and other stuff should be handled secondarily, ie with:

--pretty-expanded
--pretty-typed
--pretty-expanded-identified
--pretty-identified

Alternatively, perhaps it would make more sense to actually split it into a separate binary, called rustfmt (or, in longer-keyword land, rustformat).

Thoughts?

A seperate binary to format source code files would be cool.
The name rustformat sounds more rusty.

Is anyone working on this? I know about rustfmt, but it seems to be a dead project. Would it be reasonable to rewrite it after 1.0 release?

Yes, there is someone working on this: https://github.com/nrc/rustfmt/commits/master

@RomanTsegelskyi nrc/rustfmt is very usable and has lots to do, contributions very welcome: a list of good first issues to tackle

rustfmt is well on its way.
