<li>Emacs began at the Artificial Intelligence Laboratory at MIT. Beginning in 1972,
|
||
staff hacker CarlMikkelsen added display-editing capability to TECO, the text editor
|
||
on the AI Lab’s IncompatibleTimeSharingSystem (ITS) “Display-editing” meant that the
|
||
screen display was updated as the user entered new commands; compare the behavior of
|
||
"ed". In 1974, Richard Stallman added macro features to the TECO editor.</li>
|
||
<li>In 1976, Stallman wrote the first Emacs (“Editor MACroS”), which organized these
|
||
macros into a single command set and added facilities for SelfDocumentation and to be
|
||
extensible. TecoEmacs soon became the standard editor on ITS.</li>

<h3 id="org82bb85b"><span class="section-number-3">2.3</span> What is ELisp?</h3>

<div class="outline-text-3" id="text-2-3">
|
||
<p>
|
||
Elisp is a dialect of Lisp specifically written for Emacs. It makes it super
|
||
easy to configure Emacs if you know just a little bit of Lisp. Lovers of Erik's
|
||
scheme talk will feel right at home with ELisp! (everything is defined in terms
|
||
of elisp functions, even moving the cursor and entering text)
|
||
</p>
|
||
|
||
<p>
|
||
In fact, let's take a look at an example.
|
||
Here I will split this window into three sections:
|
||
</p>
|
||
<div class="org-src-container">
|
||
<pre class="src src-emacs-lisp">(split-window-right)
|
||
(split-window-below)
|
||
</pre>
|
||
</div>
|
||
|
||
<p>
|
||
To cycle through these windows, I press "C-x C-o".
|
||
As you can see, I cycle through in the order they were created.
|
||
</p>
|
||
|
||
<ul class="org-ul">
|
||
<li>However, what if I wanted to go back a window?
|
||
<ul class="org-ul">
|
||
<li><p>
|
||
Emacs doesn't provide a keybinding for this by default, so let's make
|
||
it in Elisp ourselves!
|
||
</p>
|
||
<div class="org-src-container">
|
||
<pre class="src src-emacs-lisp">(defun go-back-window ()
|
||
(interactive)
|
||
(other-window -1))
|
||
</pre>
|
||
</div></li>
|
||
<li><p>
|
||

|
||
</p>
|
||
<div class="org-src-container">
|

<pre class="src src-emacs-lisp">(global-set-key (kbd "C-c u") 'go-back-window)

Open Office formats, really anything you're creative enough to figure

out.

Dive right into emacs by installing it with whatever package manager you use.
|
||
Read the guide that is accessible on the default emacs start page! It will
|
||
teach you the basics. From there, just scrounge around the internet for
|
||
resources. There are plenty.
|
||
If you need a recommendation, you can start <a href="https://www.emacswiki.org/emacs/EmacsNewbie">at the emacs wiki.</a>

Let's take a look at the "evil-mode" package. This is pretty much vim

emulation within emacs. It is the best vim emulator ever; whatever vim

can do, Evil Mode can do it too.
