This tutorial is focused on Learning Emacs Lisp. I did my best to cram as much of the language into this video. While this should be more than enough to get started a few topics are still missing which I will be covering in a future video.
Let me know what you think and if there is anything specific you would like to learn about.

I really love it, I am reading "eintr" too.

well done man! 👍 One great feature I missed in this video was ‘add-advice’

@GavinFreeborn 3 месяца назад

Oh ya advice would have been worth covering. I'll add a mention of it in a future video.

@seventhtenth 3 месяца назад

thank you, I guess I will learn right now

ero-mode ... highly recommend. Evaluations show up right next to the evaluated form, rather than in the mini-buffer. yw! ^_^

@GavinFreeborn 2 месяца назад

Thanks for recommending it. Sounds like it would be good to have for some of these demos.

I used emacs for a very long time, and eLisp has a special place in my heart; however, at most places I've worked they've used vi. At least it was better than nano. The problem was always that it was a very minimal vi, not vim, so...yeah, that. The real power of using emacs comes in learning and using eLisp to extend it to do whatever you need. Same with vi? Well, not really. With vim? Yes. When you trick it out, it's usable, too. The editor wars ended over a generation ago, but it doesn't hurt to know how to drive a manual transmission as well as an automatic. To which am I referring? That's up to you to choose. 😊 Great video!!

the editor wars still exist in my heart

A lot of the "new" emacs lisp stuff was new to me! thanks for sharing your setup and knowledge! Very beautiful setup! I'm curious to check out your dot files more and see what else I can learn :)

@RubenCiencia 3 месяца назад

Great video. Thanks for this, it really help me.

@EdouardTavinor 2 месяца назад

thanks for the cool video :) i've been getting into emacs buffer programming recently, and i've started to feel more at home doing it. one thing i find overwhelming about emacs (and about common lisp) is the wealth of functions and macros. i imagine you could learn one new macro or function a day for many years :)

@maxreuv 3 месяца назад

Excellent refresher on EmacsLisp, thank you!

@GavinFreeborn 3 месяца назад

Glad it was helpful!

@zacharylarson1245 2 месяца назад

You can also set `(setq use-package-always-ensure t)` so that you don't have to put `:ensure t` in your `use-package` forms

Great video! And 10x10 is definitely 1000 😉 22:52

@bullpup1337 3 месяца назад

1000% correct can confirm

Thanks Gavin! Good explanations, appreciate the way you marked off sections so I could jump around. As a suggestion, would like more on Emacs Lisp that has to do with how it integrates with the Emacs environment. You touched on that this time with a) user functions that make use of the help system, b) hooks and c) modes. So thanks for that. My own top-of-mind thing is trying to add completion to a extant package that does not have this feature. But I bump into my own deficiency in this "integration" area frequently, so something more general welcome as well. But again, thanks for all you do!

Nice info, but why is the computer screen so spastic? jumpy cursor, jumpy highlighting and flickering blocks.

@GavinFreeborn 3 месяца назад

I think part of it comes down to the rendering frame rate missing some of my cursor movement and the rest comes from the excessive amount of cuts needed to trim this down to 30 minutes. Most of it is from the rendering unfortunately. I should really find the time to figure this out once and for all.
