Help with LSP-Mode for PHP with Intelephense

Help with LSP-Mode for PHP with Intelephense

[Cheshire Yang]

Hi all,

I need help setting up emacs as a PHP IDE. I'm using Emacs 27 on NixOS.

First, it should be noted that MELPA works for me _very_ inconsistently, though the configuration and everything looks fine. I was not able to connect to MELPA today, so I cloned lsp-mode repository from github into .emacs.d/ and loaded it in the init file. So now, I can open a PHP file and M-x lsp-mode with success. I also installed Intelephense on the operating system, through the OS package manager (nix), and confirmed that I can type `intelephense` into a terminal and the command is available.

When I run `M-x lsp` to start the server however, I get a strange error. This is the output with toggle debug on error:

Debugger entered--Lisp error: (void-function -andfn)
  (-andfn #'lsp--supports-buffer\? #'lsp--server-binary-present\?)
  (lsp--filter-clients (-andfn #'lsp--supports-buffer\? #'lsp--server-binary-present\?))
  (let (clients (matching-clients (lsp--filter-clients (-andfn #'lsp--supports-buffer\? #'lsp--server-binary-present\?)))) (cond (matching-clients (if (setq lsp--buffer-workspaces (or (and (not ...) (lsp--tr$
  (progn (let (clients (matching-clients (lsp--filter-clients (-andfn #'lsp--supports-buffer\? #'lsp--server-binary-present\?)))) (cond (matching-clients (if (setq lsp--buffer-workspaces (or (and ... ...) (l$
  (if (buffer-file-name) (progn (let (clients (matching-clients (lsp--filter-clients (-andfn #'lsp--supports-buffer\? #'lsp--server-binary-present\?)))) (cond (matching-clients (if (setq lsp--buffer-workspac$
  lsp(nil)
  funcall-interactively(lsp nil)
  call-interactively(lsp record nil)
  command-execute(lsp record)
  execute-extended-command(nil "lsp" "lsp")
  funcall-interactively(execute-extended-command nil "lsp" "lsp")
  call-interactively(execute-extended-command nil nil)
  command-execute(execute-extended-command)

I have no clue what any of that means. Any and all help would be greatly appreciated. Unfortunately, the official docs on lsp-mode and intelephense are not useful.

Thank you,

C. Yang

Emacs should already offer a PHP IDE, but other than that cool
combo :)

What exactly did you do, error message etc?

That means that some "-andfn" is missing. My hunch is that this is
part of "dash.el", a collection of functional-style bells-and-whistles.
Probably you need to install that (watch out: perhaps lsp-mode has
other dependencies you need to install).

Dash.el would be available through (m)elpa.

Cheers

Intelephense is a proprietary php language server.  There are free ones
like phpactor and serenata which I have yet to get to work with eglot.

Best,

Okay, what's a language server then?

OK so 0/3 PHP language servers are in the Debian repos what
I can see ...

I like the phpactor name!

Also I've never heard of eglot which also isn't in the repos ...
