Ask HN: What is your .emacs file like?

What are some good ways to get work done using Emacs? Ideally I would like to minimize the code I actually write as much as possible. How do you make emacs automate your work?

Don't know where I found this, but I like this little gem:

  (add-hook 'after-save-hook
    'executable-make-buffer-file-executable-if-script-p)

It automatically makes files executable that look like they are scripts. (Start with #!/some/interpreter)

I used to have yasnippet with some custom snippets, but then I kept using the custom o ones less and less to the point my last install uses the stock yasnippet package from the distro. I intend to rethink my custom, snippets and redeploy the more interesting ones.

That and loading extras and binding keys in a comfortable way.

That's a really good idea.

Now that you said that, I think I'll build some templates for commonly added files (like importing Django or GAE modules when the file is called "models.py").

Here is mine. Not too much in it. The main thing was get rid of all those annoying *~ files

(setq-default truncate-lines t) (setq truncate-partial-width-windows nil) ;; for vertically-split windows (setq inhibit-startup-message t) (setq make-backup-files nil) ; Don't want any backup files (setq auto-save-list-file-name nil) ; Don't want any .saves files (setq-default transient-mark-mode t)

Not really a tip for your dotfile, but learn about all of Emacs's autocompletion variations. There are something like five of them, ranging from basic M-/ to CEDET's context-and-semantics-sensitive code completion tool.

Nothing really special: adds a bunch of modes that I use, tweaks clipboard behaviour & appearance, displays column data & full pathname, plus opens & renames a bunch of terminals.

Oh yeah, there's a VB.NET mode in there too. That was fun.

What I really love about emacs is that it is so easy to move keys around and to assign function to keys. For example, I find this really useful on my MacBook Air keyboard:

  ;; Map option-up/down do page-up/down
  (global-set-key (kbd "ESC ") 'scroll-down)
  (global-set-key (kbd "ESC ") 'scroll-up)

Now option up/down do paging. Win.

(Probably already default in Aquamacs, but I prefer to use the 'real' Emacs.app)
