Char search in Emacs as in Vim

In VIM there is a command for char search: f. After first use it can be repeated with ;. I like to navigate in line with it. You see that you need to go to bracket in a middle of a line - you press f( and one-two ; and you are there. There's no such command in Emacs, so I had to write my own. I've managed even to implement repetition with ;.

(setq last-search-forward-char nil)

(defun search-forward-char-continue ()
(interactive)
(if (and last-search-forward-char (or (eq (symbol-function last-command) (symbol-function 'search-forward-char))
(eq last-command this-command)))
(search-forward-char last-search-forward-char)
(progn
(insert ";")
(setq last-search-forward-char nil))))

(global-set-key (kbd "M-s") 'search-forward-char)
(global-set-key (kbd ";") 'search-forward-char-continue)

Key word here is last-command. Using the same principle other commands also can be assigned to same key.

Twitter API, OAuth and decorators

In my current project I had a task to use twitter API. Twitter uses OAuth for authentication, which is pretty dreary. To avoid fiddling with it all the time, I've moved authentication to decorator. If key is available - nothing happens, just view is launched as usual. It's convenient that there's no need for additional twitter settings in user profile. Code is in article.

Supplementing settings in settings_local

For local project settings, I use old trick with settings_local file:try:from settings_local import \*except ImportError:passSo in settings_local.py we can override variables from settings.py.
