Guidance on what version the language server should run about elixir-ls HOT 2 CLOSED

Thanks. I guess that I got confused about compatibility issues/the number of instances running because of the incompatible logging changes that happened in 1.10. I think #115 is much more relevant (if the solution manages to be transparent) so closing this.

from elixir-ls.

Currently for emacs with lsp-mode I'd expect one instance of ElixirLS to run for each project because in lsp-mode the ElixirLS definition is not defined with :multi-root t. Here's a similar example for go: emacs-lsp/lsp-mode#1275

You can verify how many servers are running with M-x lsp-describe-session

My hunch is that elixir-ls should be compiled with the lowest supported version and run with the highest supported version so that it understands everything that various projects throw at it, but I'm not sure. In any case, it smells to me that "what version to run this with" is a tad under-documented.

Currently how ElixirLS works is that it is compiled with the lowest supported version (currently 1.7.4 with erlang 20.3.8.23) and then it runs on the same version that the project is running (if running via asdf) or it runs based on whatever version of elixir is installed globally.

But I just started a discussion about changing the approach used to run ElixirLS #115
