blogmore.el v2.7 There's no question that the experiment that is BlogMore has resulted in me blogging more. Although my previous setup wasn't exactly all friction, there's something about "owning" most of the tools and really knowing how they work, and being able to quickly modify them so they work "just so", that makes me more inclined to quickly write something up.

So I needed to make a second release of blogmore.el in one day: https://blog.davep.org/2026/04/04/blogmore-el-v2-7.html

SO!

I can fix my code so that the arguments to FEXPRs are not evaluated, by deferring the call to EVLIS into APPLY; but this is not what the code given on pages 70-71 does, and so my code will then not directly follow the specification in the #Lisp 1.5 Programmer's Manual;

OR,

OK, Beowulf bug. Both EVAL and APPLY in Beowulf are straight transcriptions of the mexprs on pages 70 and 71 of the #Lisp 1.5 Porgammer's Manual.

CONC is the only FEXPR I have implemented so far (and one of only FEXPRs in the manual).

The unit test for CONC fails, because EVLIS is called on […]

What Gödel discovered. ~ Stepan Parunashvili. stopa.io/post/269 #Logic #Math #Lisp #Programming

A Lisp trace of the evaluation of the function RANGE, in Beowulf. Beowulf is a recreation of Lisp 1.5, and therefore has all its prompts and error messages written in Old English. The evaluation trace naturally forms the symbol Lambda.

I've been hacking on Beowulf again, today; and I'm reminded how enchanted I am with the Beowulf logo, which sort-of designed itself.

I take no credit for it, really.

nukneval.el v1.3 Back when I first really got into writing Emacs Lisp code, one of the first things I got very used to and really fell in love with was being able to eval-last-sexp (C-x C-e) the code I was writing, either to test it right there in the buffer, or to cause it to be bound so I could use it elsewhere. It was so different from any other mode of working I'd used before and it was really addictive as a way of hacking on code.

binclock.el v1.12 Some time in the late 1990s, after I'd been using GNU Emacs for a few years[^1], I grabbed a copy of Writing GNU Emacs Extensions. While I'd obviously created and added to and tinkered with my ~/.emacs some, I'd never written any non-trivial code. I feel it was around 1998 or 1999 that I really started to get into trying to write actual extensions, thanks to that book.

OK, so as I've decided my new #Lisp prototype should use read-tables and read-macros to read anything, I need to implement `eval` before I can implement `read`!

Still, progress is being made.

obfusurl.el v2.2 This bit of Emacs Lisp absolutely comes from a more innocent time on the Internet. Looking at it, it seems I wrote the first version, at least as a proper package, back in 2001. It's very possible that I carried a non-package version of it around as part of dp-lib.el[^1] for some time before, so it might date from the late 1990s. While we weren't absolutely innocent back then, the idea of a slightly-risky-looking URL wasn't quite so bad as it is now.
