Compile error on Elixir 1.11 & Elixir 1.12

[kipcole9]

Summary

With ex_doc 0.25.5 and earmark 1.4.16, the following errors occur:

1. On Elixir 1.11 earmark does not compile
2. On Elixir 1.12 earmark produces compiler warnings however neither remediation (1) or (3) appear to work. I have not yet added :eex as a dependency since that is built into Elixir and shouldn't be required?

These errors do not appear with earmark 1.4.14.

Configuration

mix.lock for ex_cldr_dates_times is as follows. The same issues appear in at least ex_cldr_dates_times and ex_cldr_calendars. Both of these have earmark 1.4.16 in the lockfile. ex_cldr has earmark 1.4.14 in its lock file and compilation produces no errors.

Compile warning

I have tried adding :eex to :extra_applications and even adding it to :xref but these have no effect.

Compiling 13 files (.ex)
warning: EEx.eval_file/1 defined in application :eex is used by the current application but the current application does not depend on :eex. To fix this, you must do one of:

  1. If :eex is part of Erlang/Elixir, you must include it under :extra_applications inside "def application" in your mix.exs

  2. If :eex is a dependency, make sure it is listed under "def deps" in your mix.exs

  3. In case you don't want to add a requirement to :eex, you may optionally skip this warning by adding [xref: [exclude: [EEx]]] to your "def project" in mix.exs

Thank you for reporting this

I'll take care of it ASAP

[RobertDober]

BTW the eex warning is fixed

[RobertDober]

fixed in #427
