Please do not send PRs for those, as it will take a while until we can effectively accept them.

If you want to, you may want to check out the new possible return values from edlin_expand:expand/1,2 introduced in https://github.com/erlang/otp/pull/5924.

https://github.com/erlang/otp/blob/master/lib/stdlib/src/edlin_expand.erl#L41-L47

It allows the expand function to return structured data so that you can group completions. In Erlang we use it to make completions like this:

1> h<TAB>
bifs
halt(    hd(
commands
h(          hcb(        help(       history(    ht(

How about :erlang.nodes/2 added in https://github.com/erlang/otp/pull/6007 and released in OTP 25.1?

epinault commented 12 months ago

hello, I am finding an issue that maybe is something not yet implemented but in OTP 26 the follow code breaks

Mix.Task.get("phx.new").

I had a mix task that tries to detect if phoenix is installed by detecting the mix task above. All worked till OTP 26. but in OTP 26 it cannot find the code being loaded somehow. Any idea ? We are seeing that a lot with atom (to_existiing_atom failing in our code base and having to force loading the module before so the atom are available)

Hi @epinault, please use the ElixirForum or do a complete bug report, I don't want to sidetrack the existing issues.

epinault commented 12 months ago

done https://github.com/elixir-lang/elixir/issues/13116 (so if people find this they know where I moved the issue to)

michallepicki commented 1 month ago

👋🏻 Hello! I see one point that requires Erlang 26 is ticked off. Does this mean Elixir 1.18 will require 26, and the remaining points can be worked on now, or was werl just deprecated for long enough?

josevalim commented 1 month ago

The rich shell will require 26 on Windows in the new version because maintaining both, and 27, was not possible.
