Someone please correct me if I’m wrong but I believe the use case here is that your language server, if using the same version of Elixir going forward, is running and compiles your application then it would serve that purpose for you.
Whether the LSPs do that yet with 1.18, I’m not sure but I believe that is the idea going forward
But yes, if you were editing without an LSP running, and no new request came in, then it would not be recompiled. You’d need some other OS process to watch and manually recompile on save.
The LSP approach is likely your best option though, since presumably you’d be in your editor anyway
haven’t really thought about restarting iex since recompile returns :noop
