Emacs lisp manual

The Emacs Lisp Reference Manual (also known as the elisp or lispref) manual, is documentation about the language used to extend Emacs, EmacsLisp. GnuEmacs has an EmacsManual, an EmacsLispIntro, and an EmacsLispReference. Starting with Emacs 22, all three manuals are included.  · An Introduction to Programming in Emacs Lisp. This manual is available in the following formats: HTML - with one web page per node. HTML - entirely on one web page. Info document. PostScript file. PDF file. Texinfo source. You can also purchase a printed copy from the FSF store. Most of the GNU Emacs integrated environment is written in the programming language called Emacs Lisp. The code written in this programming language is the software—the sets of instructions—that tell the computer what to do when you give.

Emacs Lisp provides the traditional four arithmetic operations: addition, subtraction, multiplication, and division. Remainder and modulus functions supplement the division functions. The functions to add or subtract 1 are provided because they are traditional in Lisp and commonly used. Loading a file of Lisp code means bringing its contents into the Lisp environment in the form of Lisp objects. Emacs finds and opens the file, reads the text, evaluates each form, and then closes the file. The load functions evaluate all the expressions in a file just as the eval-current-buffer function evaluates all the expressions in a buffer. The difference is that the load functions read and evaluate the text in the file as found on disk, not the text in an Emacs buffer.
