LispUsers is a collection of user contributed software that has been shipping with Interlisp and later Medley since the 1970s. To load a LispUsers program evaluate (IL:FILESLOAD file) where `file` is the program name without extension. Most come with .pdf or .TEDIT documentation that explains how to run the program.

Published in 1987, "Xerox LOOPS, A Friendly Primer" is a concise tutorial to the LOOPS (Lisp Object-Oriented Programming System) object extension of Interlisp. Some chapters of this copy are in the wrong order but all the content is there.

You can use the Interlisp function SHOWGRAPH to display a graph of an S-exp laid out by LAYOUTSEXPR, as in this example of the syntax tree of a setence. More details in the documentation of the grapher library module of Medley:

Screenshot of a portion of the black and white desktop of a 1980s graphical workstation environment. The desktop has a gray background pattern and a window with a white background and a title bar with white text on a black background. The window is a Lisp REPL where the following expression is evaluated:

(SHOWGRAPH (LAYOUTSEXPR '(S (NP (DET The) (NOUN program (VP (VERB displays) (NP (DET a) (NOUN tree)))))) '(VERTICAL) NIL '(HELVETICA 12 BRR)))

Beneath the REPL window is a graphical window that displays the syntax tree represented by the expression.

My quick notes on the downloadable interview discussion with @vnikolov and @kentpitman About Vassil's assertables classed toggleable assertion macro design.

Provokes lots of fascinating historical notes from Kent about what the ANSI CL and earlier standardisations were doing and had in mind.

On May 28, 2025 Eleanor Young will give the talk "The Medley Interlisp Project: Reviving a Historical Software System" at the 2025 IEEE Canadian Conference on Electrical and Computer Engineering and Industry Summit (CCECE). She will discuss what other historical software recovery groups can learn from the Medley Interlisp Project.

#softwareEngineering #programming #commonLisp #assertions #algebra - tight, efficient #lazyEvaluation vector multiplication with #series .
https://screwlisp.small-web.org/programming/cl-series-vector-mult-assert-lisp-interactivity/

I use assert in lisp, which automatically generates an interactive in-context failure resolution which I utilize in the article, where the lazy cotruncation series feature was not wanted. Shows off a #lisp useage: classic.

@vnikolov what do you think of this example of assert viz your assertables?
+ @kentpitman

An emacs slime lisp repl from the article:
CL-USER> (funcall * '(1 2) '((3) (4)))
11
CL-USER> (funcall ** '(1 2) '((3) (4) (5)))
The old value of A is (1 2).
Do you want to supply a new value? (y or n) n
The old value of B is ((3) (4) (5)).
Do you want to supply a new value? (y or n) y
Type a form to be evaluated:
'((3) (4))

In which I look at modern and to some extent historical static program analysis popularly used with common lisp #programming.

I accidentally make the really good point that even if #sbcl is not your deployment target, you can still use its static type checking, for which I work an example.

#lazyEvaluation and formal theorems are also included.

Kinda rushed, but I show the kitten server operator and kitten visitors interacting in real time (the kitten visitor by hitting a kitten page, the kitten server operator by reading and setting kittendb values in the kitten shell).

What do you think @mdhughes @aral

Obviously the kitten host will be robotic, but I thought this is a useful half-interaction to see.

The Structure of a Programming
Language
Revolution
's
reference to Teitelman's thesis on advice in the 60s, while already tired from writing my other article today.

An Xemacs window showing, in the top frame:
```

I imagine someone younger than me who never as a young child witnessed
an adult unironically using word perfect- well, I don't need to
imagine them. Go to a university- they never experienced life before
Microsoft 365 Office and Google Cloud Documents. I am very impressed
with everyone even later than me who is pulling themselves up by their
own bootstraps into old computing, and/or my dear lisp.

Alright, I really was out of steam.

Oh, the article I was referencing before was titled:

The Structure of a Programming
```

And in the bottom frame a bunch of warnings about keymaps.
