Partial failure to handle Elixir 1.15-dev. Omens of incompatibility! #478

I can recreate it with asdf on If you launch Elixir 14: iex(8)> :prettypr.text('hi')
{:text, [2, 104, 105]}Elixir main-otp25: iex(2)> :prettypr.text('hi')
** (UndefinedFunctionError) function :prettypr.text/1 is undefined (module :prettypr is not available)
:prettypr.text(~c"hi") |

It's a bit peculiar, as in |
|
FWIW, I'm trying to manually build up some PLTs and run dialyzer afterwards in this set up. |

@cognivore We needed to add some dependencies to extra_applications. can you try with dialyxir |
|
Will do!

@jeremyjh you fixed it so quickly! It's so much appreciated. It indeed works with the latest commit in upstream! Thank you! P.S. I've confirmed that this works on real projects too. I think this can be closed. |
Elixir versions >= 1.15 seem to be unable to find the :prettypr module,
causing errors like the following:

nixfrom this commit.Current behavior
Dialyzer works but it displays a huge wall of errors while building PLTs / being ran the first time.
They are of three problems types:
prettyptrnot foundEnum.reduce/3is not a function andString.t/0is not a type (it means that Elixir wasn't dialyzed?!)As you see even the first time in this particular project, dialyzer run happens, later on it's business as usual:
In another project, however, it won't run at all:
Expected behavior
It's expected that dialyxir either crashes catastrofically on both projects, signaling incompatibility with 1.15-dev, or works correctly, returning the results.
