On this page discussing font lock mode , an example is provided which highlights a custom pattern: (add-hook 'c-mode-hook (lambda () (font-lock-add-keywords nil '(("\\<\\(FIXME\\):" 1 font-lock-warning-face t))))) Is there a way to provide a custom color instead of font-lock-warning-face and without defining a new custom face. I want to be able to write something like: (font-lock-add-keywords nil '(("\\<\\(FIXME\\):" 1 "Blue" t))) or an RGB color definition: (font-lock-add-keywords nil '(("\\<\\(FIXME\\):" 1 "#F0F0F0" t))) Using the double quotes doesn't work. Do you know what will make it

I am manually constructing path strings in Elisp by concatenating partial paths and directory names. Unfortunately sometimes the paths end with slash, sometimes not. Therefore, I need to insert slash before concatenating a directory name when necessary but not otherwise. What's a good way to do this? (file-name-as-directory dir) will return directory path dir with a trailing slash, adding one if necessary, and not otherwise. If you had your sequence of partial paths in a list, you could do something like: (let ((directory-list '("/foo" "bar/" "p/q/" "x/y")) (file-name "some_file.el")) (concat

I have been a programmer for a decade now, but I believe this is the first time I've ever asked a question on a forum. I just can't figure this out and can't find the answer already online. I am trying to turn on CUA mode so that emacs is more bearable for a windows user (normal copy paste functions). I am running Windows 7 and installed emacs through the Lisp In A Box package. I understand that I need to add a line to my .emacs file or init.el file. I'm not sure which, but I can't find either in my Lip In A Box install directory. The emacs package install also did not come with any tutorials

When reading either of these questions or the EmacsWiki article about mapping Caps Lock to Control in emacs in Windows, the best answers seem to involve the registry. My question is what a user can do when they can't modify the registry of the machine because they don't have admin rights. Is there a way to do the mapping from within emacs? This article comes oh-so-close, even saying, "As people have mentioned, you can of course map Caps-Lock to other keys instead, for example the Control key." But I can't figure out how to represent the control key (using various references that look pretty

how would I figure this out? I added delete-trailing-whitespace to the before-save-hook in my c-mode-common-hook , but it looks like delete-trailing-whitespace is getting called for every file, not just buffers using c-mode and derivatives. Can I make the before-save-hook buffer local? Emerick Rogul Add it to write-contents-functions instead: (add-hook 'c-mode-common-hook (lambda() (add-hook 'write-contents-functions (lambda() (save-excursion (delete-trailing-whitespace))) nil t))) As the Emacs Lisp Reference Manual explains: This works just like write-file-functions, but it is intended for

Is it possible to let Emacs have the cursor be moved off-screen, like most GUI text editors work? This is one of the biggest things that bothers me when I use Emacs over any GUI editor. When I scroll down, the cursor is "pushed forward" by the top of the buffer. I had previously thought that this was completely impossible, because this is hard-wired into the architecture of Emacs, but then I saw multiple-cursors , which does exactly this for the secondary cursors (assuming you prevent the scrolling functions from acting on the secondary cursors). Is it maybe possible to use multiple-cursors to
