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

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

console $ 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, UTF-8 files only)
