Copy and pasted from the Emacs FAQ, http://www.gnu.org/software/emacs/windows/: Where do I put my init file? On Windows, the .emacs file may be called _emacs for backward compatibility with DOS and FAT filesystems where filenames could not start with a dot. Some users prefer to continue using such a name, because Windows Explorer cannot create a file … Read more
M-x read-only-mode in very old versions of Emacs, the command was: M-x toggle-read-only On my Windows box, that amounts to Alt-x to bring up the meta prompt and typing “read-only-mode” to call the correct elisp function. If you are using the default keyboard bindings, C-x C-q (which you read aloud as “Control-X Control-Q”) will have … Read more
Here’s a thought: The macro binds a flet function (rails-project:root) one time to the value that (rails-project:root) has just before the body executes. (That’s how it claims a performance increase: Apparently the outer (rails-project:root) is expensive, so calling once and caching the value seems like a good idea.) Unfortunately, if there is code inside the … Read more
; list the packages you want (setq package-list ‘(package1 package2)) ; list the repositories containing them (setq package-archives ‘((“elpa” . “http://tromey.com/elpa/”) (“gnu” . “http://elpa.gnu.org/packages/”) (“marmalade” . “http://marmalade-repo.org/packages/”))) ; activate all the packages (in particular autoloads) (package-initialize) ; fetch the list of packages available (unless package-archive-contents (package-refresh-contents)) ; install the missing packages (dolist (package package-list) (unless … Read more
js-indent-level can be used in the default javascript-mode, which is included by default starting in emacs 23.2. (setq js-indent-level 2) should do what you’re looking for. If you’re using an older version of emacs, you may be in java-mode. I think this mode responds to c-basic-offset, however I may be wrong.
C-a # Go to beginning of line C-k # Kill line from current point There is also C-S-backspace # Ctrl-Shift-Backspace which invokes M-x kill-whole-line. If you’d like to set a different global key binding, you’d put this in ~/.emacs: (global-set-key “\C-cd” ‘kill-whole-line) # Sets `C-c d` to `M-x kill-whole-line` If you want to delete a … Read more
Folding is generally unnecessary with emacs, as it has tools that explicitly implement the actions people do manually when folding code. Most people have good success with simple incremental searches. See “foo” mentioned somewhere? Type C-sfoo, find the definition, press enter, read it, and then press C-x C-x to go back to where you were. … Read more
If you are programming Python using Emacs, then you should probably be using python-mode. With python-mode, after marking the block of code, C-c > or C-c C-l shifts the region 4 spaces to the right C-c < or C-c C-r shifts the region 4 spaces to the left If you need to shift code by … Read more
Emacs takes many launch options. The one that you are looking for is emacs -nw. This will open Emacs inside the terminal disregarding the DISPLAY environment variable even if it is set. The long form of this flag is emacs –no-window-system. More information about Emacs launch options can be found in the manual.
to create the directory dir/to/create, type: M-x make-directory RET dir/to/create RET to create directories dir/parent1/node and dir/parent2/node, type: M-! mkdir -p dir/parent{1,2}/node RET It assumes that Emacs’s inferior shell is bash/zsh or other compatible shell. or in a Dired mode + It doesn’t create nonexistent parent directories.
