Why does byte-compiling the the following produce a warning? (defmacro foomacro (shiftcode) `(defun foo (&optional arg) (interactive ,(concat shiftcode "p")) (message "arg is %i" arg)) `(defun bar (&optional arg) (interactive ,(concat shiftcode "Nenter a number: ")) (message "arg is %i" arg))) ;; provide backward compatibility for Emacs 22 (if (fboundp 'handle-shift-selection) (foomacro "^") (foomacro "")) This is the warning I get: $ emacs -Q --batch --eval '(byte-compile-file "foo.el")' In foomacro: foo.el:1:21:Warning: value returned from (concat shiftcode "p") is unused If I get rid of bar

On upgrading from Emacs 23 to Emacs 24, filename completion suddenly became case sensitive in shell-mode . I had customized Emacs 23 to be case insensitive in this case but I forget the exact customizations now. Going over my .emacs file, I see that read-file-name-completion-ignore-case is set to non-nil. However, that seems to have no effect in Emacs 24's shell-mode . So it turns out that shell-mode in Emacs 24 uses pcomplete by default . pcomplete was always the default for eshell but Emacs 24 has made it so for shell too. pcomplete-ignore-case controls case sensitivity for pcomplete . I got

I'm having a hard time understanding exactly how macro expansion works. What is the difference in how the elisp interpreter handles these two snippets of code? (defmacro foo (arg) (message "arg is: %s" arg)) (foo "bar") and: (defmacro foo (arg) `(message "arg is: %s" ,arg)) (foo "bar") You example may be confusing because message both displays a message and returns it. strings (like "bar") are self-evaluating. Instructive Example (defconst zzz 123) (defmacro zzz1 (arg) `(insert (format "arg is: %s" ,arg))) (defmacro zzz2 (arg) (insert (format "arg is: %s" arg))) Evaluate the code above using C

I often work with differents active buffer on emacs like : source files SQL buffer shell buffer I try to get speedbar always display buffer mode but I can't find any option that can load this display when emacs is started (default is file mode), and keep it during all session. I also tried ecb history window that can display opened/recently closed edit buffers but there's no way to make it display specials buffers like SQL or shell. How can I customize emacs to get this behavior? I know this question is really old, but I'm going to answer it for anyone searching out there. I did this with a

I use Emacs only for \LaTeX and python programming. Is there a way to automatically turn on flyspell-mode when I work on a .tex file, and turn on flyspell-prog-mode when I work on a .py file? How can I do this in my .emacs file? Add those functions to hooks of python-mode and latex-mode (require 'python) ;; If you use tex-mode (require 'tex-mode)` (add-hook 'latex-mode-hook 'flyspell-mode) ;; If you use AUCTeX (load "auctex.el" nil t t)` (add-hook 'LaTeX-mode-hook 'flyspell-mode) (add-hook 'python-mode-hook 'flyspell-prog-mode) Something like this should work. (setq auto-mode-alist (cons '("\\

I'm using web-mode in Emacs to get syntax highlighting and indentation for PHP and HTML. If I have this code in a .php file <p> Lorem ipsum dolor sit amet, consectetur adipiscing elit. </p> And then put the cursor on the middle line and press tab then nothing happens. I want it to look like this: <p> Lorem ipsum dolor sit amet, consectetur adipiscing elit. </p> If I put the text in a tag on a single line and try to indent, it works. This: <p> <a>Lorem ipsum dolor sit amet, consectetur adipiscing elit.</a> </p> turns into this, which it should <p> <a>Lorem ipsum dolor sit amet, consectetur
