> It seems that eglot expects the scala metals LSP server binary to be named `metals-emacs` instead of `metals`. The included patch fixes this behaviour. At least in the nix package manager the `metals` binary is simply call 'metals'. However if other package managers distribute an alias for the binary as 'metals-emacs' as well we could instead do something like:
> ```
> (scala-mode . ,(eglot-alternatives '("metals" "metals-emacs"))
> ```

Looking at this site:

  https://github.com/rossabaker/lsp-scala

I see this:

  (defcustom lsp-scala-server-command "metals-emacs"
    "The command to launch the Scala language server."
    :group 'lsp-scala
  :type 'file)

So maybe we do need to support both names.

João, WDYT?
