Sv: Sv: Sv: Christmas wish: Literate Elisp

[arthur miller]

As info; my bytecomp patch has bug, don't use it

(just don't bytecompile) when you test, last version

won't produce .elc file. I don't have time to fix it today.

C patch works fine (with eval-buffer or eval-region ).

Here are all 4 files again with simple.patch for lisp/simple.el.

Hope it works for you.

Sorry, I should have written a longer message, with most, or all,
parts of it written in the first person...

In my experience hanging out at the #emacs channel at Freenode and
asking for help or hints on elisp is fun, and it's easy to test ideas
interactively with C-x C-e... asking for help on the C side of Emacs
is not so fun - patching the C source is considered arcane knowledge
(<- my impression!) and fewer people will be able to discuss that and
to help... also, I don't know how to recompile Emacs after a change in
a .c and restart it in less that 30 seconds (slow machine here - I use
an old ThinkPad with LibreBoot) - in fact I don't think I've ever
patched the C source before! Here's the script that I used to test
Arthur's patch:

Interesting 🙂. If you have red my previous mails to this list you

might have noticed that I am not an elisp guru. Stefan has 

outlined two possible ways how this could be implemented in 

Elisp, if you follow his advice I am sure you will have a working 

solution you can present to us. I don't care how many lines of code

it will take.
