The GP’s response is very curmudgeonly and feels like the poster asked a question on Stack Overflow.

A mocking response also doesn’t count as a joke response. A joke response would be good-natured and not at the expense of the poster. I agree that it is more of a mocking. And mocking new users isn’t a helpful form of discourse - no matter how tired someone is of their style of questions.

I do appreciate that your response was much more earnest and trying to engage with the poster.

I think I have to disagree, if they want things that work and are full-featured out of the box - then the community packages like lsp-mode and Company and Swiper are much better alternatives 🤷🏼

Unfortunately, if you either don’t have the time or don’t want to spend the time configuring Emacs - the best I can recommend for you is to use a distribution. And I can see that you’re already using the most VSCode distribution, Doom. I like Doom because it sticks fairly closely to Emacs’ conventions (compared to Spacemacs), has a large user base, and enabling most features just involves uncommenting some lines. Doom also has a pretty good discord to join.

If you haven’t seen this tutorial series, it goes over some of the features in Doom in a short videos. It might be out of data on some parts - given that /u/zaiste started this series 5 years ago.

If you want to build your own configuration from scratch Then maybe check out System Crafters (note that’s like 12 hours of videos) on the idea https://www.youtube.com/watch?v=74zOY-vgkyw&list=PLEoMzSkcN8oPH1au7H6B7bBJ4ZO7BXjSZ

To answer your actual querstion:

1. Org-mode
2. Magit
3. Multiple-Cursors
4. LSP-Mode
5. Flycheck
6. Company
7. Ido/Swiper/Ivy
8. Projectile

none of these are language specific but they build up Emacs to have the modern features of an IDE that I care about. Connecting up the languages to work with these packages is left as an exercise for the reader. Though they can look at my garbage pile of a config if they’re really stuck.
