When Emacs needs your input, it asks in a special one-line area at the bottom of the currently active frame called the mini-buffer. Buffers are where you interact with Emacs. Buffers can contain the contents of files, the output of commands, the lists of menu options, or other items. Within each window, the contents displayed are called a buffer. Emacs frames initially contain a single window, but you can open multiple windows in each frame, either manually or by running special commands. The panes within each Emacs frame are referred to as windows. You can open as many Emacs frames as you wish, on as many monitors as you wish, and Emacs will track them all. The window you see when you start Emacs is referred to as a frame.

Since these terms have different meanings now, it’s a good idea to review them, as you’ll be reading about them as the tutorial progresses: Note: In this tutorial, Emacs keystrokes are shown as Ctrl + X Ctrl + S.Įmacs uses some terminology that can be traced back to its text-based UNIX roots. You’ll be greeted with the following passage: You can access it by positioning the cursor over the words Emacs Tutorial on the Emacs start screen and pressing Enter, or by typing Ctrl + H T at any time thereafter. The easiest way to learn which keys do what in Emacs is to follow the built-in tutorial.

If you try to paste code into Emacs, for instance, then you may find the standard Ctrl + V keystroke doesn’t work. There are some odd key mappings in Emacs, however.

Emacs responds as expected to the arrow keys, as well as the Enter, Backspace, Del, Home, End, and Tab keys.

Emacs highlights the opening bracket or parenthesis whenever you type a closing bracket or parenthesis.

Emacs changes the indentation to appropriate locations when you hit Tab on an indented line.

Emacs indents lines following for and if statements automatically.

Emacs highlights variables and constants differently from Python keywords.

You may recognize this code as the Sieve of Eratosthenes, which finds all primes below a given maximum.

#AQUAMACS SAMPLE CODE INSTALL#

Install Emacs on your selected platform.

In this tutorial, you’ll learn about using Emacs for Python development, including how to: To this day, GNU Emacs and the XEmacs variant are available on every major platform, and GNU Emacs continues to be a combatant in the Editor Wars. It was adopted into the GNU project by Richard Stallman in the early 1980s, and GNU Emacs has been continuously maintained and developed ever since. One of the most feature-rich editors available is Emacs.Įmacs started in the mid-1970s as a set of macro extensions for a different code editor. Then, you can try to find editors that have those features. To choose the right code editor, you have to start by knowing which features are important to you. Many developers explore numerous editors as they grow and learn. Finding the right code editor for Python development can be tricky.
