Indentation breaks on first line of file

[purcell]

Given

|
module Foo where
...

where | denotes point, indentation raises an error:

Debugger entered: ((cl-assertion-failed (<= start end) nil))
  cl--assertion-failed((<= start end))
  elm-indent-in-comment(2 1)
  elm-indent-indentation-info()
  elm-indent-cycle()
  indent-for-tab-command(nil)
  funcall-interactively(indent-for-tab-command nil)
  #<subr call-interactively>(indent-for-tab-command nil nil)
  ad-Advice-call-interactively(#<subr call-interactively> indent-for-tab-command nil nil)
  apply(ad-Advice-call-interactively #<subr call-interactively> (indent-for-tab-command nil nil))
  call-interactively(indent-for-tab-command nil nil)
  command-execute(indent-for-tab-command)

This appears to be because - in elm-indent-indentation-info, elm-indent-start-of-def returns a position greater than (point). Not obvious to me what the most correct fix for this would be, sorry.

I am not able to replicate this issue.

I have a module

|
module Card exposing(..)

import Html exposing (Html, Attribute, text, div, input, span)
...

for me, with my cursor at the m in module, I don't get an error.

changing the new elm exposing(..) syntax to where also doesn't raise an error.

Are you still experiencing this issue?

Thanks for the comment! That's not quite the case I described, though: cursor should be on the empty leading line. And then, yes, the error is still present for me.

[HParker]

Ah, thanks! I thought that was meant as a downward arrow. I see it as well now.

Yay, great. Thanks.
