I was looking for an Emacs Lisp book that covers how to customize and extend the Emacs environment in Lisp, not just the language or the editor, and a new edition of this book crossed my feeds. I guess I have something to read over the winter holydays.

@amoroso what is the Emacs environment, beyond the editor and the language?
@amoroso
Writing gnu emacs extensions is an old O'Reilly book that is still perfectly applicable. I have the original in paperback. It had a giraffe on it. Still available for purchase and available for free numerous places in pdf. I even found it on GitHub in org format.
Here's the first hit in my search. A pdf.
@Zenie That's a good book too, back in the day I also had the original paperback.
@amoroso I'm not sure I have the book anymore. I lost most of my books.
@Zenie My copy is in the basement, in a box buried among other boxes and still unopened since I moved to a new house several years ago.
@amoroso
Mine is in a similar place, on another continent.
If it is still there. It was helpful back in 97.
New material is always nice.
I've read enough of Mickey Peterson's posts that I feel I should buy his book, Mastering Emacs.
After 30 years of emacs there is still a lot to learn.
I often do things the old way only to find that Elisp has new functions I could use instead. I'm happy to see the influences of other lisps appearing.
