* THIS PHLOG AS SUCH :actually_the_phlog:
** SLIME LISP CLOS
is an ANSI standard extending the lisp standard to present and accept
interactions by means other than simply a character stream.

The open source child of clim is named McCLIM and it's over here:
[[https://codeberg.org/McCLIM]]

OR SO I PLANNED but instead this is a sm0l introduction to programming
in lisp at all and with an orgmode slime session, and clos
particularly.

*** Start slime
#+name: slime
#+begin_src elisp
(slime)
#+end_src
*** Writing a package without clim
Actually, I'm not sure how to start slime without opening a window
that needs to be closed (C-x 5 0).

I believe slime includes loading the inferior lisp's asdf
implementation so we don't have to (require :asdf).

Here I'm learning myself, and I know that I want clim to make the
interface, rather than trying to fiddle it myself.

So I'm thinking something like a list of counts and names that
I can #'pairlis together. Something like this
#+name: pairlis
#+begin_src lisp
(defvar *counts* '(0 0 0))
(defvar *names* '(a b c))
#+end_src
sorry about the vulgar style. I often like to just setq like this when
I'm just noodling. Then maybe we would like to #'incf a count based on
a name.
#+name:incf-by-name
#+HEADER: :noweb yes :results none
#+begin_src lisp
<<pairlis()>>
(Defun incf-by-name (name)
(let ((idx (search `(,name) *names*)))
(when idx (incf (car (nthcdr idx *counts*))))))
#+end_src
I tried to use noweb to inline having called whatever pairlis() was
for the side effect. #'defvar means multiple calls to that don't reset
their value. Now maybe a function for using that that takes an arg
#+name: %increase-name
#+HEADER: :var count-name=()
#+begin_src lisp
(incf-by-name count-name)
#+end_src

this should just work right? call_%increase-name(count-name='a) {{{results(=3=)}}}

#+CALL: %increase-name(count-name='a)

#+RESULTS:
: 2

#+CALL: %increase-name(count-name='b)

#+RESULTS:
: 1

there isn't really a cute way to turn that special scope stuff into a
class, so I'm just quickly rewriting it.
**** name-count class
#+name: defining-name-count-class
#+begin_src lisp
(defclass named-counts ()
((count-names :initarg :count-names :Type 'list :accessor count-names)
(counts-of :initarg :initial-counts-of :Type 'list :Accessor counts-of)))
(defmethod increase-name ((name symbol) (obj named-counts))
(let ((idx (search `(,name) (count-names obj))))
(when idx (incf (car (nthcdr idx (counts-of obj)))))))

;;Oh let's just make a special one (like how *application-frame* will be special)
(defvar *named-counter*
(make-instance 'named-counts
:count-names '(a b c)
:initial-counts-of '(-3 -2 -1)))
#+end_src

#+RESULTS: defining-name-count-class
: #<NAMED-COUNTS {1003904183}>

and the actual
#+name: increase-name
#+header: :var count-name=()
#+begin_src lisp
(increase-name count-name *named-counter*)
#+end_src
with the example named-counter. #+call_increase-name(count-name='c) {{{results(=2=)}}}

#+CALL: increase-name(count-name='b)

#+RESULTS:
: -1

We did some programming. I am thinking of using something like this with derangements later.

Let's see about graphicalising this.

*** require mcclim
OKAY I forgot that McCLIM also uses swank so we need to start slime using McCLIM's swank.

I feel like this phost went on a bit, so let's leave slime clim to the next one.
