“ Emacs is the extensible, customizable, self-documenting real-time display editor.”– Emacs Manual
In simple words, emacs is an editor, like vi or nano. You may not be familiar with these editors as they are mainly found on the Unix/Unix-like systems.
Emacs is an advanced editor because of its ability to perform complex operations related to OS, by controlling subprocesses, indenting programs automatically, showing multiple files at once and of course, it can be used as a text editor as well :).
It is also a self-documenting means any time special command for help can be used for finding out what the particular command does. Emacs can be easily altered to behave in a certain preference and is highly customizable.
Emacs can go beyond simple customization and can create entirely new commands. These new commands are simple to program and can be written in LISP.
I downloaded for MAC OS X as I am using Mac from http://emacsformacosx.com/. I had been suggested by many sites and also from the people on IRC #emacs channel, while you are learning to use emacs, do not start with a customized emacs. I believe it could be mainly because a lot of customizations are already done for you, hence limiting your learning curve. Well, downloading and installing with OS X is pretty simple and straight, I got “Emacs Version 24.3 Universal Binary Released 2013-03-11”. Double click on the installer and voila the installation is completed on the fly.
GNU Emacs development is hosted on savannah.gnu.org.
Working with emacs
Starting the editor: once downloaded and installed. From the Launchpad -> emacs, clicking on which took me to the editor in its full glory, with a nice welcome message with a link to the manual and the beginner emacs tutorials to get a start working with emacs and to quickly get help in emacs “C-h (Hold down Ctrl and Press h)
Few things to note and which are global to emacs.
- Control Key in emacs is denoted as ‘C’.
- Alt or Esc Key in emacs is denoted as’ or referred in the document as meta key.
- The shift key will be denoted as ‘S’.
The first command to know is how to exit from emacs to normal prompt.
Use C-x C-c to quit emacs,
If you have written something in the editor use C-x C-s(save file) C-x C-c(Quit Emacs).
You can also use the X(cross icon on the right-hand side) in the window manager to just come out of emacs.
Most movements in emacs can be controlled using the arrow keys but there are still debates and emacsgurus do not advise to use arrows keys still say it is not advisable and the use of key sequences controlled by Ctrl and Meta keys are advisable. below table helps in understanding the movements with these keys.</tr> </tr> </tbody> </table> These are some of the common keys for moving around while in emacs. It seems its really hard for getting used to it, but as I am working with emacs for some time, I started to feel it is most obvious to be like that. I think most of the time as a beginner we could get along with using the arrow keys and we should highly discourage it and use the emacs specific keybindings to move around within emacs. Apart from bringing the emacs on and starting it up, the very important thing we should remember is how to close it. During my initial days as emacs user, I was not aware of quitting emacs, and have of the time ended in killing emacs from the process tree, now I feel so stupid. C-g and C-x C-c are the commands, which can help you all the time, while we are learning. I have heard more advanced user of emacs seldom close their emacs sessions and I may try to forget using C-x C-C again. It may take some time till I get there and stop closing my emacs and I am sure it would be more than 30 days.
