could you send me the template ?

@fxbois Hi. I'm using web-mode df57cd0beea9c6bdc64259bd11bde0c076a64cc9 (from MELPA) but work fine.

However, I confirmed that I get the same error occur that @uskebasi reported after update to 9586a44b05d8bfdef2371461d896db01737dfee1 (latest master commit) from MELPA.

I think it's better to revert the master branch to df57cd0beea9c6bdc64259bd11bde0c076a64cc9, what do you think?

(Thanks: @uskebasi 👍)

Could you tell me how to trigger the bug ?

[debiru]

I am currently installing Emacs (GNU Emacs 27.1) on Ubuntu 22.04. I too have encountered this problem.

Could you tell me how to trigger the bug ?

$ cat ~/.emacs.d/init.el
(require 'package)
(add-to-list 'package-archives '("melpa" . "https://melpa.org/packages/") t)
(package-initialize)

(setq package-list '(web-mode))

(unless package-archive-contents
  (package-refresh-contents))

(dolist (package package-list)
  (unless (package-installed-p package)
    (package-install package)))

(require 'web-mode)
(add-to-list 'auto-mode-alist '("\\.html\\'" . web-mode))

The trigger is to open any html file after install web-mode (20231223.1924) by melpa package. Then can't open the file and Emacs says Args out of range: "", 0 in footer field.

I investigated this in the environment at hand, but on Ubuntu 20.04 (GNU Emacs 26.3) and macOS X (GNU Emacs 28.1), I was able to open the file in web-mode without error after following the same procedure. Perhaps the reproducibility may vary depending on the OS.

@debiru Good job, Thanks! 👍

@fxbois I also wrote a minimal configuration init.el:

;;; init.el --- "GNU Emacs" main config file to composition for debug -*- lexical-binding: t; -*-

;;; Commentary:

;; This GNU Emacs config file is minimum composition for debug.

;;; Code:

(setq debug-on-error t)

(require 'package)
(add-to-list 'package-archives '("MELPA" . "https://melpa.org/packages/"))
(package-initialize)
(package-refresh-contents)

;; `web-mode'
(package-install 'web-mode)
(add-to-list 'auto-mode-alist '("\\.html\\'" . web-mode))

;; Local Variables:
;; coding: utf-8-unix
;; mode: Emacs-Lisp
;; no-byte-compile: t
;; End:

;;; init.el ends here

The startup command is:

emacs -nw --init-directory=~/.emacs.d.minimum

Below is my GNU Emacs environment (Please let me know if you would like additional information):

• GNU Emacs 29.1 (Stable)
• macOS 13.6.3 (Ventura)
• Bash 5.2.21

Below is a test HTML file:

<!doctype html>
<html lang="en">
  <head>
    <meta charset="UTF-8" />
    <title>Test</title>
  </head>
  <body>
    <h1>Hello, World!</h1>
    <p>Paragraph</p>
  </body>
</html>

Finally, here is the stack trace when opening the HTML file mentioned above:

I would be happy if you could use it as a reference 🙏

[debiru]

Note: Workaround for those encountering the same problem.

Use stable.melpa.org instead of melpa.org.

(setq package-archives '(("melpa-stable" . "https://stable.melpa.org/packages/")))
(package-initialize)

1. delete current package. M-x package-delete web-mode
2. install as stable package. M-x package-install web-mode

You can install web-mode-17.3.13 instead of web-mode-20231223.1924.

[fxbois]

thank you @takueof , I'll work on this today

[fxbois]

should be fixed with last commit ... sorry to have disturbed your studious Christmas Holidays !

[takueof]

@fxbois I'm installed web-mode 20231225.1458 via MELPA, and verified that the problem was fixed! Thank you for your quick fix even during the holiday season 🙏

Happy holidays (and hacking)! 🎄
