Error in post-command-hook (file-error "Doing vfork" "Not a directory")

[yudi-matsuzake]

I've been trying and I could not configure and use eglot-ltex. I open any file that is assigned to text-mode and nothing happens. Similar error messages keep being logged in *Messages* for different files. Please, let me know if I am missing something.

My Emacs version is 29.2 and Output of ltex-ls --version:

{
  "ltex-ls": "16.0.0",
  "java": "21.0.2"
}

The error logged to *Messages* is

Error in post-command-hook (#[0 "\303\301!\205�\0r\301q\210\304\305\300\242\306#\210

Minimal init.el file

;; straight package bootstrap
(defvar bootstrap-version)
(let ((bootstrap-file
       (expand-file-name
        "straight/repos/straight.el/bootstrap.el"
        user-emacs-directory))
      (bootstrap-version 6))

  (unless (file-exists-p bootstrap-file)
    (with-current-buffer
        (url-retrieve-synchronously
         "https://raw.githubusercontent.com/radian-software/straight.el/develop/install.el"
         'silent 'inhibit-cookies)
      (goto-char (point-max))
      (eval-print-last-sexp)))
  (load bootstrap-file nil 'nomessage))

(use-package eglot)

(use-package eglot-ltex
  :straight (eglot-ltex
    :type git
    :host github
    :repo "emacs-languagetool/eglot-ltex")
  :hook (text-mode . (lambda ()
     (require 'eglot-ltex)
     (eglot-ensure)))
  :init
    (setq eglot-languagetool-server-path "/usr/bin/ltex-ls"))

Command that I used to run the minimal configuration:

emacs -Q --init-directory=/tmp/emacs --eval '(load-file "init.el")'

I hope this is sufficient to reproduce this error. Otherwise, let me know.

Your settings looks correct. Maybe try https://github.com/emacs-languagetool/lsp-ltex?tab=readme-ov-file#-quickstart section. 🤔

[yudi-matsuzake]

Using lsp-mode and lsp-ltex works with my installation of ltex! But I am still struggling to make the eglot-ltex to work :(

[yudi-matsuzake]

I am with a working setup now. Firstly, in my init.el the variable that is assigned is eglot-languagetool-server-path which is the wrong variable name. After changing this, a similar error persists. Then I downgrade the ltex to the version 15.0.2. Now everything works as expected.

Is this package expected to work with ltexversion 16.0.1?

Thank you for your attention!

[jcs090218]

Is this package expected to work with ltexversion 16.0.1?

It should... I will need to investigate this. May be some setup has changed overtime.

Just for the clarification, does 16.0.1 works on lsp-ltex? Or both eglot and lsp-mode clients aren't working? 🤔

[yudi-matsuzake]

Oh! I think I misspelled the version, the version that I tried is 16.0.0.

For clarity, in my setup the 16.0.0 version works with lsp-mode/lsp-ltex and not with eglot/eglot-ltex.

This is the minimal init.el that I tried lsp-mode/lsp-ltex and works as expected:

;; straight package bootstrap
(defvar bootstrap-version)
(let ((bootstrap-file
       (expand-file-name
        "straight/repos/straight.el/bootstrap.el"
        user-emacs-directory))
      (bootstrap-version 6))

  (unless (file-exists-p bootstrap-file)
    (with-current-buffer
        (url-retrieve-synchronously
         "https://raw.githubusercontent.com/radian-software/straight.el/develop/install.el"
         'silent 'inhibit-cookies)
      (goto-char (point-max))
      (eval-print-last-sexp)))
  (load bootstrap-file nil 'nomessage))

(use-package lsp-mode
  :straight t)

(use-package lsp-ltex
  :straight t
  :hook
    (text-mode . (lambda ()
      (require 'lsp-ltex)
      (lsp)))
  :init
    (setq lsp-ltex-version "16.0.0"))

This is the minimal init.el that I tried eglot/eglot-ltex using the same .dir-locals.el of the README.md:

(defvar bootstrap-version)
(let ((bootstrap-file
       (expand-file-name
        "straight/repos/straight.el/bootstrap.el"
        user-emacs-directory))
      (bootstrap-version 6))

  (unless (file-exists-p bootstrap-file)
    (with-current-buffer
        (url-retrieve-synchronously
         "https://raw.githubusercontent.com/radian-software/straight.el/develop/install.el"
         'silent 'inhibit-cookies)
      (goto-char (point-max))
      (eval-print-last-sexp)))
  (load bootstrap-file nil 'nomessage))

(use-package eglot)

(use-package eglot-ltex
  :straight (eglot-ltex
    :type git
    :host github
    :repo "emacs-languagetool/eglot-ltex")
  :hook (text-mode . (lambda ()
     (require 'eglot-ltex)
     (eglot-ensure)))
  :init
    (setq eglot-ltex-server-path "/usr/share/ltex-ls/"))

When I open a text-mode file in the eglot-ltex setup this is logged to the *Messages* buffer:

Loading init.el (source)...done

Finally, in the *EGLOT (....)* buffer:
