If you (require ‘cl) then you can use the Common Lisp function reduce. Pass the keyword argument :from-end t for foldr. ELISP> (reduce #’list ‘(1 2 3 4)) (((1 2) 3) 4) ELISP> (reduce #’list ‘(1 2 3 4) :from-end t) (1 (2 (3 4)))
Seems you are using an old emacs/vc/vc-hg version. Simply upgrading is probably the easiest solution. I had a similar problem, which I could solve bit by bit by improving small settings and even made a patch. It never really solved all. Until I upgrade to a recent emacs (and support file); I use the Aquamacs … Read more
To track the problem down, you can try this: (setq max-specpdl-size 5) ; default is 1000, reduce the backtrace level (setq debug-on-error t) ; now you should get a backtrace C-h a ; in speedbar You should get a backtrace upon the error, and at that point, you can track down the offending routine. I’d … Read more
From Joe Grossberg’s blog (no longer available): But if you’re using GNU Emacs 21.2 (the latest version, which includes this as part of the standard distro), you can just put the following lines into your .emacs file ;; recentf stuff (require ‘recentf) (recentf-mode 1) (setq recentf-max-menu-items 25) (global-set-key “\C-x\ \C-r” ‘recentf-open-files) Then, when you launch … Read more
Activate org-indent-mode. One way is to add a hook (add-hook ‘org-mode-hook (lambda () (org-indent-mode t)) t) but the easier way is to customize org-startup-indented to be non-nil. Note that even when org-indent-mode is non-nil, headlines still don’t enjoy auto-fill treatment. It’s only the body of an entry that will be both filled and indented left-justified … Read more
The problem here is that Emacs believes any modifier key (control, shift, meta etc) can be applied to any regular key. This is true when Emacs is talking directly to the OS, but not when it’s running inside a traditional (pseudo-)terminal, which is what you’ve got when you’re using emacs inside ssh. In that case, … Read more
Emacs 24 has built-in theming, which doesn’t use statements like (require ‘color-theme). As Drew points out in the comments, there are differences between color themes and custom themes, and the new direction is towards the latter. Try M-x customize-themes to take a look. From .emacs, you can do things like (load-theme ‘wombat t). But… It … Read more
On http://orgmode.org/manual/Special-symbols.html I found the solution to the double spacing problem: Org e.g.\nbsp{}example LaTeX e.g.~example
Just to clarify (it is in the quoted docs that Charlie cites) (interactive) is not just for key-bound functions, but for any function. Without (interactive), it can only be called programmatically, not from M-x (or via key-binding). EDIT: Note that just adding “(interactive)” to a function won’t necessarily make it work that way, either — … Read more
If you take a look at the documentation for add-hook (or C-h f add-hook RET), you’ll see that one possible solution is to make the hook local to the major modes you want. This is slightly more involved than vderyagin’s answer, and looks like this: (add-hook ‘org-mode-hook (lambda () (add-hook ‘after-save-hook ‘a-test-save-hook nil ‘make-it-local))) The … Read more
