Reading and Writing Buffers in Practice - Learning Emacs Lisp #5

[@highamnj]

Thanks for the section markers in the video - very useful!

[@SystemCrafters]

Thanks! With a video this long, it's a necessity :)

[@auroradraco9974]

Yes, finally the next episode of learning Elisp. I have been waiting for this, its a very interesting concept and I have learned many things already. Cant wait to watch this

[@SystemCrafters]

Let me know your thoughts after watching it! I'm trying a slightly different approach this time to see if it helps demonstrate better the usage of what we cover.

[@auroradraco9974]

@@SystemCrafters Yeah, I like this approach. I didn't mind the previous one though either. Both get the message delivered properly imo

[@VipinBalakrishnan]

Always learning. Thanks for the amazing content.

[@neilmoon4478]

I fucking love you and this series thank you so much

[@lassekliemann6251]

Could you do a video one day on theory and best practices for writing own minor modes? The biggest challenge I am facing is to properly restore the previous state when the minor is disabled some time after being enabled. Thanks!

[@Ggldoork]

Great as usual!

[@inversebrah]

great stuff ✌️

[@anoopanthony]

I'm lucky to have a couple of videos with no dislikes!

Great presentations, thanks a lot for them. This one is particularly interesting if you are interested in writing you own packages.
One question: what is the package you are using to display the commands in the modeline as you type?

[@SystemCrafters]

Thanks Pedro! That is the Keycast package, you can see my config for it at the end of the code block in this section of my dotfiles: github.com/daviwil/dotfiles/blob/master/Emacs.org#streaming

[@cateru8053]

is there a way to add arrgument completion in typescript lsp mode??
and thanks alot

[@AndersJackson]

Great presentation, like always.
1) What happen if there are two spaces after :tangel? Maybe search forward to beginning of next word?
2) What if something else is added to end of .ignore file? Maybe add and end tag, not just start tag?

[@abarocio80]

For number 1, you could replace «(search-forward ":tangle " nil t)» with «(search-forward-regexp ":tangle +" nil t)».

[@abarocio80]

For number 2, you could paste the following in your scratch buffer and execute it. It searches for a start-marker and saves the point, then does the same for an end-marker, and also saves the point, then using those two points, deletes the region between those points and writes back something else.
;; START-MARKER
Here we could put many, many things
;; Even comments
;; END-MARKER
(save-excursion
(beginning-of-buffer)
(search-forward-regexp "^;; START-MARKER" nil t)
(beginning-of-line)
(let ((start-point (point)))
(search-forward-regexp "^;; END-MARKER" nil t)
(end-of-line)
(let ((end-point (point)))
(delete-region start-point end-point)))
(insert ";; START-MARKER
")
(insert "
;; This was fun!

")
(insert ";; END-MARKER
")
)
Have fun!

👍👍

[@MarcoPrevedello92]

Just my 2 cents: what about "dotctor.el"?

[@SystemCrafters]

Not bad! Though I think I would say it wrong every single time :)

[@abarocio80]

RUclips keeps deleting my comments! I didn't do it!!!

[@SystemCrafters]

Argh, I wonder if it considered the code Snippets spam? Sorry about that!

[@abarocio80]

@@SystemCrafters Yea, may be. Thanks, any way!
