Do you need to know Lisp to use Emacs?
No, it’s not strictly necessary. You will probably write elisp, but mostly just set variables and insert the necessary snippets for any mode or package you want to use ( setq , require etc). Most of that is done by copying and pasting, so no real knowledge of elisp is required.
How do I run a lisp in Emacs?
To load an Emacs Lisp file, type M-x load-file . This command reads a file name using the minibuffer, and executes the contents of that file as Emacs Lisp code. It is not necessary to visit the file first; this command reads the file directly from disk, not from an existing Emacs buffer.
What is require package Emacs?
If you load a library repeatedly, that file will be read and its code evaluated repeatedly (each and every time you load it). If you require a library repeatedly, it will load the library once (at most — and not at all if the library had already been loaded).
What is Emacs load path?
The value of variable ‘load-path’ is a list of directories to search, in order, for EmacsLisp libraries that you load. If you do not alter it (directly or indirectly), by default it contains the Lisp source directories for the Emacs distribution.
How do I run an Emacs file?
To execute a file of Emacs Lisp code, use M-x load-file . This command reads a file name using the minibuffer and then executes the contents of that file as Lisp code. It is not necessary to visit the file first; in any case, this command reads the file as found on disk, not text in an Emacs buffer.
How do I run a lisp?
Step 1: After logging into a CUIT machine, enter “lisp” after the $ shell prompt and then hit . Another way is to run lisp via emacs: Meta-x run-lisp (i.e. hit ‘esc’ followed by ‘x’, type “run-lisp” and you’ll be in lisp mode from which you can load files of lisp code…)
Should I use use package Emacs?
require is a core function in emacs. use-package does many things and features more than require. It can download a package if you don’t have it, can set keys and other customization for a package, etc. ‘
What is require package?
Require: Installing and Loading R Packages for Reproducible Workflows. As with other functions in a reproducible workflow, this package emphasizes functions that return the same result whether it is the first or subsequent times running the function.
Where does Emacs look for El files?
/usr/share/emacs
el is located at /usr/share/emacs/site-lisp/Macaulay2/M2-init. el, and emacs already knows to look in that directory for source files. The simplest way to teach emacs how to find M2-init.
Do you need a Common Lisp library for Emacs?
See Info node (cl). If you need only Common Lisp macros, that is, you do not need any Common Lisp functions at runtime, then you can just require library ` cl-lib.el ’ (or library ` cl.el ’) a compile time, like this:
What does it mean to require a file in Emacs?
Using ‘require’ adds a dependency: Not only must a file with the same name (plus “.el” or “.elc” extension) exist, but in that file, Emacs wants to see a statement such as this: Thus, in your package, you can ‘require’ several so-called features.
Where can I find the GNU Emacs Manual?

Is there CL lib.el in Emacs 24.3?
As noted above, GNU Emacs earlier than 24.3 and XEmacs don’t come with cl-lib.el. They instead have cl.el which provides the same functions, but is somewhat problematic as it defines them in the global namespace rather than prefixing with ‘cl-’. See Coding Conventions:
