If you haven't yet I'd recommend going through the tutorial and looking at the elisp manual. Both are accessible if you press `C-h i` (there's a lot of other goodies in the list of manuals you get there, the calc one is great).

Except on Debian and Debian-derived systems. Apparently there's an issue with license compatibility, on those you may need to install this package: emacs-common-non-dfsg. But on pretty much every other system with a standard emacs install, yes, `C-h i` is all you need to get to the documentation.

Ill definitely give that a go. I feel like I NEED to learn Lisp. My college data structures prof had his own book where all the java examples had a lisp counterpart. He wouldn’t allow us to use normal Java data structures for assignments rather a lisp data structure called “cons”. Not sure how different elisp and lisp is but syntax wise they look identical to me.

  If you know some Common Lisp, Emacs Lisp isn't hard to learn (and they're even closer than when I learned elisp 15-20 years ago). Some minor gotchas with literal syntax (literal arrays/vectors and chars are represented differently in each) and some differences in their standard libraries. A more major gotcha is elisp's dynamic scope, which comes up if you're used to lexical scope. https://www.gnu.org/software/emacs/manual/html_node/elisp/Dynamic-Binding.html https://www.gnu.org/software/emacs/manual/html_node/elisp/Dy... In practice, I've never been bitten by this except when I tried to do some fancier functional programming things in elisp that I normally would use another language for. And you can specify that you want lexical scope: https://www.gnu.org/software/emacs/manual/html_node/elisp/Lexical-Binding.html https://www.gnu.org/software/emacs/manual/html_node/elisp/Le... The whole section those two come from: https://www.gnu.org/software/emacs/manual/html_node/elisp/Variable-Scoping.html https://www.gnu.org/software/emacs/manual/html_node/elisp/Va...

    Very cool. Thanks for the info. https://www.cs.utexas.edu/users/novak/cs31436.html https://www.cs.utexas.edu/users/novak/cs31436.html this is the book i mentioned earlier if you’re interested. e.g. of building a linked list I might go through some of it purely in lisp for the heck of it.
