(elixir) interpolation, sigils and / functions

Update 11/2019: As far as I know #2257 leaves only item 3 open.

• 1) Interpolation: It cannot deal properly with interpolation.
• 2) Sigils : It cannot deal with these ~S sigil. ~s is fine though.
• 3) Function with a slash ( “Kernel./” ): this one takes /: as the beggining of a regular expression (Closed via #2406)

We are adding hightlightjs to https://github.com/elixir-lang/ex_doc/ and when I ran it against the test file for pygments. In addition to #707, I have run into three new issues:

1. Interpolation: It cannot deal properly with interpolation.

Every single line bellow, has an issues, it takes it as a comment whatever comes after the #

~R'this + i\s "a" regex too'
~w(hello #{ ["has" <> "123", '\c\d', "\123 interpol" | []] } world)s
~W(hello #{no "123" \c\d \123 interpol} world)s
~s{Escapes terminators \{ and \}, but no {balancing} # outside of sigil here }
~S"No escapes \s\t\n and no #{interpolation}"

1. Sigils : It cannot deal with these ~S sigil. ~s is fine though.

defmodule Long.Module.Name do
  @doc ~S'''
  No #{interpolation} of any kind.
  \000 \x{ff}

  \n #{\x{ff}}
  '''
  def func(a, b \\ []), do: :ok

  @doc ~S"""
  No #{interpolation} of any kind.
  \000 \x{ff}

  \n #{\x{ff}}
  """
  def func(a, b \\ []), do: :ok
end

1. Function with a slash ( “Kernel./” ): this one takes /: as the beggining of a regular expression

import Kernel, except: [spawn: 1, +: 2, /: 2, Unless: 2]

@eksperimental Sounds like you’re busy - and I haven’t gotten around to this either. I’m just going to run with this as it. It passes all the original examples provided. If there are additional edge cases we can just let people file them as they see them.

Thanks for the offer to help though!

Cool. Thank you!
