efmt

Erlang code formatter.

NOTICE This crate is still in the development phase. So the formatting style can be radically changed in the future.

Examples

$ echo 'foo() -> bar.' | efmt
foo() ->
    bar.

$ echo 'foo(x) -> y; foo(A) -> [{A, A}, A].' | efmt --max-columns 10
foo(x) ->
    y;
foo(A) ->
    [{A,
      A},
     A].

Limitations

TODO (e.g., broken forms in an unreachable -if. branch, parse-transform)
