Hi,

I edit pages of a wiki (FOSWiki), which, when opened in Emacs via the
Firefox extension "Edit with Emacs", end up in buffers with names like
the following:

wiki.zedat.fu-berlin.de/bin/edit/SCS/ScsProtokoll20230816?t=1692000848;nowysiwyg=1

I would like to associate these with a specific mode and therefore have

(add-to-list 'auto-mode-alist '("wiki\\.zedat\\.fu-berlin\\.de/bin/edit/SCS/.*" . erin-mode))

in my setup. However, the mode is not selected. What is wrong with my
regexp?

Cheers,

Loris

Your regexp is probably off. auto-mode-alist is a regexp for the type of
file. that would be everything after the `.'

i just downloaded the extension and it works great. Try and run M-x
server-start first.

from my emacs file:

;; .emacs.el

;; start emacs server mode
(server-start)

;; append paths to auto-mode-alist
;; check for duplicates with rassoc
(unless (rassoc 'html-mode auto-mode-alist)
(setq auto-mode-alist
(append auto-mode-alist
'(("\\.txt\\'" . rst-mode)
("\\.html?\\'" . html-mode)
("\\.rest\\'" . rst-mode)
("\\.md\\'" . rst-mode)
("^README.*" . rst-mode)
("\\.\$pp\\|dpr\\|dpk\\|inc\$\\'" . pascal-mode)
("\\.fpc\\'" . makefile-gmake-mode)
("\\.cl\\'" . lisp-mode )
("\\.asd\\'" . lisp-mode)))))

;; hook function to modify html-mode
(defun si::html-mode-hook ()
"Function to run when new HTML buffer is created."
(setq sgml-basic-offset 2)
(message "Editing a HTML file: %s" (buffer-file-name (current-buffer))))

(add-hook 'html-mode-hook 'si::html-mode-hook)

< in my setup. However, the mode is not selected. What is wrong with my
< regexp?

the regexp should be looking for *.html$ that means ending with .html.

hope this helps
