vscode can only be customized by an extension. There's a bunch of one off plugins you have to install to get little bits of functionality that you can get by pasting 15 lines of elisp from the emacs wiki. If no one has built that extension yet, you have to learn to build one yourself. You could always create private "personal" extension and keep it local, but that workflow is tedious. I'm not saying vscode is less ex…

I'd argue this is a feature more than a bug. I haven't done much with VSC, but I have done a lot with both atom and emacs (via spacemacs). How do you find out even the name of what you are looking for to find it on the wiki? Is that snippet of elisp tested (or even testable?) What does it do exactly? Is it a passive effect, or something you have to execute a command to run?

In atom, you can find packages on the website or in the dedicated search in the editor. Popular packages get featured, so you can hear about things you wouldn't even know to ask for. Instead of static code, you get free updates whenever they're available. The code in most packages is tested. All the information on how it works is in the Readme.

Emacs is awesome, and currently more customizable than anything else. Tramp and Magit and Evil are best in class. But it's super difficult for a newbie to get started, and the windows compatibility is only so-so.

If you really want to just use code snippets to customize atom, you can! They have an init file for code changes, and a css file for style changes. There's even a website where you can find some of these little scripts: https://www.atom-tweaks.com/

Acme does this, and I love it, but most people's response to seeing Acme is "what the hell? No syntax highlighting? No autocomplete?" You can also easily create a second "view" into a file with the Zerox command, which is a nice way to look at two parts of a file at once.

It's the best thing I've found for managing large numbers of buffers at once, though, and with things like acmego (go fmt + add missing imports on save) and Go guru integration (jump straight to function definition) it suits my needs pretty well.

The undo system is confusing if you are accustomed to undo/redo in practically every other piece of software, but it does make sense (in its own kind of way). See the documentation for the undo commmand[1]. Emacs undo is powerful albeit with more cognitive load to use. I have occasionally had to take over the controls for new emacs users while pair programming because the undo, while logical and consistent, doesn’t w…

Anyone that wants to use emacs seriously has to learn a about the kill ring. Something like Helm kill ring is great. It lets you go way back in time and re-pasted killed things.

The problem with this is I'm a web dev and I can't really do all my work in emacs. For backend people you can live entirely in emacs. Once you hit the frontend you have to start interacting with a browser. That's why I always get a clipboard manager and have my editor kill (cut) to the clipboard. Then I can hit C-V and get a popup menu (similar to helm kill ring, navigable both with mouse and keyboard) with the last 100 or so things I've cut/copied.

Same. I used to swear by Intellij but they just kept on changing things, and even breaking things on me the odd time. This latest emacs upgrade has been seamless and hasn't required any cognitive overhead to transition. That said, I'll always be back to IntelliJ for heavy edits. There's nothing better for Java. I find for less structured languages the less-structured approach engendered by emacs is an advantage.

emacs has a couple of packages working to implement the editor side of the language server protocol, so it's probably not long until it's at rough feature parity for structured editing of languages with rich semantics.

If you're using a ceremonious language like Java, the automation in a modern editor could be useful. I think that's what Gosling was getting at.

Java by many definitions is a bit like assembly language of our current times.

You will end up stitching highly verbose pieces of code. Which is why Java IDEs have specific features to emit get/set functions etc.

Plus you will have to access a method hiding 5 class layers below. You will need IDEs designed to do this sort of work really well.

Emacs and Vi have been designed to largely play with Text, plus I think with Java's verbosity you are just better off with a specialized IDE.

I see this occasionally. Why can't you edit locally?

Sometimes it’s policy (no source code on laptops), but mostly it’s because my line of work uses the verilog language and the tool suites require “very stable” (read: archaic) versions of Linux.

do you know about TRAMP? https://www.emacswiki.org/emacs/TrampMode

For some perspective: BBEdit - launched in 1992 (26 years ago), still around. Notepad++ - launched in 2003 (15 years ago), still around. Textmate - launched in 2004 (14 years ago), still around. Sublime - launched in 2008 (10 years ago), still around. Almost all the mainstream editors since 1995 at least are around. They have been marginalized, but they're generally around. Especially cross platform editors and even…

To see why this isn't necessarily the case, add to your list all the text editors launched between 1992 and 2008 that are no longer around ("being around" defined as being able to install and run on whatever OS you're using on your main computer with no special effort).

VS Code and Atom are practically guaranteed to run until the end of time at this point. The sole benefit of web apps is that they're more likely to remain functional than native ones.

Can you use ssh/scp? Emacs is able to use that to edit files remotely. I often use it when I work with small Arm Linux boards.

Emacs has this too. You can look at a buffer from different windows, or clone-indirect-buffer in order to edit multiple parts of it simultaneously.
