;; that's for initial installation
;; (load "~/Downloads/quicklisp.lisp")

;; that prints into repl -
;; (quicklisp-quickstart:help) and (quicklisp-quickstart:install) are paths forward
;; would I maybe want to install it with nix?
;;
;; I could try
;; I guess it works, there's binary and /lib in ~/.nix-profille
;; /home/efim/.nix-profile/lib/common-lisp/quicklisp/setup.lisp

;; so, "loading after installation" from https://www.quicklisp.org/beta/#loading
;; is what I'd want

;; (load "~/.nix-profile/lib/common-lisp/quicklisp/setup.lisp")
;; error! "Can't create directory", welp
;; then how would I load it?
;; do I need to modify sbcl startup?
;; sbcl is also installed with nix, so it could probably integrate loading of quicklisp?

;;; welp, I've asked a question on discourse
;; maybe somebody will help, and then I'd document this
;; https://discourse.nixos.org/t/how-to-use-quicklisp-with-sbcl/20539

;; I'll proceed with manual installation
;; https://www.quicklisp.org/beta/#loading

;; well, that seems to work. with manual step of adding to ~/.sblcrc
;; now restarting sly I have quicklisp
;; I guess that's ok

;;; Now, how to use it?
;; one commad is already present in installation guide
(ql:system-apropos "vecto")
(ql:system-apropos "matrix")
(ql:system-apropos "cells")

;; and there's
#'ql:quickload

;; and counterpart
#'ql:uninstall

;; this is of course absolutely not pure or nixy
;; ok, now, I just go about reading on the packages themselves, and there's not much on the quicklisp?
;; maybe

;;; could look into "awesome-cl" list
;; maybe I'd find something to play with
;; https://github.com/CodyReichert/awesome-cl

;;; ?? what is "in-package"?
(ql:quickload "fset")

(in-package fset-user)
(isetq s (map ('a 2) :default 1))


(in-package cl-user)
(isetq s (map ('a 2) :default 1))       ; error, yay

;; promising things to look at are
