Not starting on OTP26

[lukaszsamson]

There are several issues that make ElixirLS fail on OTP26. Some of them are already addressed on https://github.com/elixir-lsp/elixir-ls/tree/otp26 but some will need to wait for fixes upstream

• dialyzer changed some internal APIs we depend on
• changes in stdio interception
• calling self now crashes io
• OTP26 has critical bugs in stdio, e.g. [OTP 26] Unexpected conversion when transferring data over stdout erlang/otp#7132 Erlang/OTP 26 stdin fails on file:read/file:read_line erlang/otp#7230
• stdio hangs on Windows Erlang/OTP 26 write to stdout hangs in latin1 encoding on Windows erlang/otp#7459

Hi, I just wanted to add that it does not work with the released version of Erlang 26.0.
I am running elixir-ls in LunarVim and get this in the LspLog

Even with the OTP26 branch with master merged in things are working much, much better ;)

It crashes on first utf character in client request

I see one crash, and then it seems to work fine after that.. (where previously it would just crash repeatedly.)
I merged master into a local copy of this branch and recompiled. I'm using Elixir 1.15 and OTP 26.0.1

Not saying it's fixed. But it's actually usable right now for me...
