`An Introduction to Programming in Emacs Lisp’ (Elisp Intro), is an Elisp tutorial that comes with Emacs. Elisp, is short for Emacs Lisp, which is a dialect of the Lisp programming language. It is mainly used for writing extensions for the GNU Emacs editor and it can also be used as a scripting language in a way like Perl or Python.
After reaching a certain level in using Emacs, it is not enough to simply copy and paste others’ code for Emacs configuration, this is the main reason why I read Elisp Intro. I also wanted to gain some knowledge of a Lisp dialect that would be useful in (my) real world.
