Emacs Lisp expression for matching beginning of filename in `auto-mode-alist`


Emacs Lisp expression for matching beginning of filename in `auto-mode-alist`

hope this fix your issue The regex specified as part of auto-mode-alist matches against the full pathname, so both of your regular expressions will never match against anything.
You probably want to use something like
code :
(add-to-list 'auto-mode-alist '("Makefile.*\\'" . makefile-mode))
(add-to-list 'auto-mode-alist '("/Makefile.*\\'" . makefile-mode))

I wish this helpful for you This is probably silly but I don't have enough Elisp knowledge to understand what is going on with respect to quoting and evaluation. , Try this:
code :
(setq my-frame-width 100)
(setq my-frame-height 50)
(add-to-list 'default-frame-alist `(width . ,my-frame-width))
(add-to-list 'default-frame-alist `(height . ,my-frame-height))

it fixes the issue Not a direct answer, but company works fine out of the box in emacs-lisp-mode, so you might want to try that one.

Hope this helps There are essentially two questions here. One is how to remove the element from the list. The other is how to automatically open *.m files in octave-mode. You shouldn't need to remove the element to override it. The provided form
code :
(add-to-list 'auto-mode-alist ("\\.m$" . octave-mode))
(add-to-list 'auto-mode-alist '("\\.m$" . octave-mode))
(add-to-list 'auto-mode-alist '("\\.m\\'" . octave-mode))
(setq auto-mode-alist (delete '("\\.m\\'" . objc-mode) auto-mode-alist))
(require 'cl-lib)
(cl-remove "\\.m\\'" auto-mode-alist :test 'equal :key 'car)

Hope this helps Remember that arguments to macros are un-evaluated, which means that when you pass my-vars-alist as an argument, it is passed verbatim as the symbol my-vars-alist.
Therefore during the macro expansion, vars-alist evaluates to the symbol my-vars-alist rather than the list ((var1 . "var1") (var2 . "var2")).
code :
,@(mapcar (lambda (cell) (list (car cell) (cdr cell)))
          (eval vars-alist))
