Emacs back references in replace-regex.

From http://www.gnu.org/software/emacs/manual/html_node/emacs/Regexp-Replace.html

In replace-regexp, the newstring need not be constant: it can refer to all or part of what is matched by the regexp. ‘\&’ in newstring stands for the entire match being replaced. ‘\d’ in newstring, where d is a digit, stands for whatever matched the dth parenthesized grouping in regexp. (This is called a “back reference.”) ‘\#’ refers to the count of replacements already made in this command, as a decimal number. In the first replacement, ‘\#’ stands for ‘0’; in the second, for ‘1’; and so on. For example,

M-x replace-regexp <RET> c[ad]+r <RET> \&-safe <RET>

replaces (for example) ‘cadr’ with ‘cadr-safe’ and ‘cddr’ with ‘cddr-safe’.

Finally figured out how to stop this message from popping up after every key stroke if I've launched emacs from a terminal.

Modify the entry in /usr/share/themes/Ambiance/gtk-2.0/gtkrc from GtkRange::trough-under-steppers = 0 to GtkRange::trough-under-steppers = 1. Change Ambiance to whatever theme you are using.

Running functions on marked files in dired mode for emacs.

Source

If you have some function, say some custom refactoring operation, you can call it from a dired buffer, and have it run on each marked file, using the code below.

Go into a dired buffer, mark some files, and then do M-x and run your command. In this case it would be test-for-each-dired-marked-file

;;; iterating over files in dired

;;; usage example - for-each-dired-marked-file returns a filename and path
;;; for each marked file, so this is what a function using it looks like
(defun view-stuff(filename)
"opens up the file and gets the length of it, then messages the result"
(let (fpath fname mybuffer len)
  (setq fpath filename)
  (setq fname (file-name-nondirectory fpath))
  (setq mybuffer (find-file fpath))
  (setq len (buffer-size))
  (kill-buffer mybuffer)
  (message "Buffer length %d %s" len (buffer-file-name mybuffer))))

; Usage example
(defun test-for-each-dired-marked-file()
(interactive)
(for-each-dired-marked-file 'view-stuff))

(defun for-each-dired-marked-file(fn)
"Do stuff for each marked file, only works in dired window"
(interactive)
(if (eq major-mode 'dired-mode)
   (let ((filenames (dired-get-marked-files)))
     (mapcar fn filenames))
 (error (format "Not a Dired buffer \(%s\)" major-mode))))

A co-worker wrote a nice little lisp snippet for emacs to indent the entire buffer. I should modify it to indent a marked region, if there isn't code to do this already.

(defun indent-whole-buffer ()
"Indent the entire buffer"
(interactive)
(indent-region 0 (buffer-size)))

Convert DOS files to unix in emacs.

Essentially, C-x RET f undecided-unix

Emacs Dired mode quick reference.

Some particular highlights are:

• To enter Dired mode simply do C-x C-f and select a directory
• To open a file or directory, move the cursor to the name of the file you want to edit and hit enter (or e)
  
• Create a directory - +
• Copy a file - S[hift]-c
• Move/rename a file - S-r
• Delete a file by pressing `d` to mark it for deletion, then press `x` to process all marked files. Press `u` to deselect a file marked for deletion.
• Press `~` to mark all backup files in the current directory for deletion (again, use `x` to actually remove them).
• Refresh the Dired screen with `g`
• Diff two files with `=`
• Mark a file with `m` and then perform a shell command on said marked files with `!`. You can also just run a command with `!`. For example, download a zip file with `!wget www.com/somezipfile.zip` and then with that zipfile under the cursor, run `!unzip`
  
• And the coolest bit, you can use regex to rename groups of files in a directory with %r. If you have Main.as and Main.2.as and you want to rename them to main.as and main.2.as, you can do `Main\(.+\).as` to `main\1.as`
