Ops, you are right. That example was because of the "sane indentation" plugin, that I installed in the hope to get better indentation. Below is an example where plain Atom, without plugins, doesn't get indentation right (notice how it pushes "onEmailChange" under "login"):

  const login = (email, password, remember) => a.chain(
    submitting(true),
    a.ajax({
      request: {
        url: '/api/sessions',
        method: 'POST',
        data: { email, password },
      },
      callback: (status, data) => (
        a.chain(submitting(false),
        a.setToken(data.token, remember),
        a.setUserId(data.userId),
        a.setAuth)),
      })
    )

    const onEmailChange = (push, value) => {
      push(emailChange(value))
    }

This is something you're copying and pasting in or you're simply writing it out? Also am I missing something or are you missing some syntax (callback has no starting brace)? Also if `const onEmailChange` shouldn't be pushed out then don't you need to end your const login sooner? I don't see where it's ended here.

Granted maybe this is just some truncated example? I hadn't run into weird spacing like this yet so maybe open a bug with something small with reproduction steps?

It is something I am writing, then selecting-all and applying auto-indentation.

`onEmailChange` doesn't even have an open or close curly bracket, it is the indentation format that is confusing us. Below is the same code indented by VS.

  const login = (email, password, remember) => a.chain(
    submitting(true),
    a.ajax({
      request: {
        url: '/api/sessions',
        method: 'POST',
        data: { email, password },
      },
      callback: (status, data) => (
        a.chain(submitting(false),
          a.setToken(data.token, remember),
          a.setUserId(data.userId),
          a.setAuth)),
    })
  )

  const onEmailChange = (push, value) => {
    push(emailChange(value))
  }

`const onEmailChange` shouldn't be under `login`. If you count the brackets you will see that `login` ends before `onEmailChange` starts. But for some reason Atom doesn't understand that.

Maybe my syntax is different than most, but I see problems like this all the time with Atom. The exact same files indent fine in VS.

Regarding filing a bug, I thought about it, but then I didn't think anybody would care about this.

Hmm interesting. I tried typing out similar syntax but it seems to be indenting correctly. Then again I don't use much ES6 if at all. So not sure. I'm sure they would care though :)
