Linux

This is a very cool list, I will try some. The feature I am looking for is not included in the overview so I'll have to just try. Unless someone can suggest which app has this feature: I want to be able to click/double click a quote to select the text between the quotes. This to easily replace text between quotes. On MacOS I used to use BBEdit which has this feature. But now I'm on linux so looking for a replacement. (I do know the ci' vi-command but am looking for a GUI editor). I use Fedora KDE Plasma

Apologies for not being clear, and thank you for probing me to answer the right questions:

• I'm not married to Markdown or any other markup language, but it is true that Markdown makes up my primary use case.
• Though, with emacs installed, I've also dabbled into org-mode. And while I've been liking it so far, I understand that it's mostly an emacs thing.
• I suppose my current needs would mostly be fulfilled with Markdown + LaTeX.

Here’s Eclipse, for example.

Thank you for mentioning Eclipse! Will look into it!

This has a "text folding" and "code folding" column.

Wow, that's pretty neat! Very much appreciated!

thanks! looking into JED now

Thank you for mentioning Kate! The GNOME-fanboy inside of me would probs like to resist it, but sometimes KDE's offering is strictly better^[I absolutely adore Okular.] at least IMO*. I'll look into it and see if it satisfies my needs.

It’s a GUI and not a TUI though. Not sure if that was a requirement as well

That wasn't a requirement. Regardless, thank you for the heads up!

If they ever roll out plugins, or whatever. There's a lot of functionality piled up behind that.

Edit: I was wrong. It's going to be in core. It's just been "in progress" for two years because (a) there have been prerequisite blockers slowly getting implemented, (b) it's hard, in part because of other Helix features like multiple cursors, and (c) the guy implementing it (and who can implement it is, in his words, limited to a couple of people with deep Helix knowledge) hasn't had time.

Hopefully it will receive it soon*; my Helix-installation has been collecting dust ever since the folding-workflow has been growing on me.

Scite can do it.

Noted. Thank you!

Notepad++ probably too but I don’t know if it’s available on Linux.

FWIW, someone else pointed out the existence of Notepad Next. Which IIUC is pretty much an open-source and cross-platform reimplementation.

I just remember it being the text editor to use on Windows.

Frankly, I never used it when I was using Windows 😅. I suppose I was (somehow) conditioned at the time to use whatever M$ Office offered instead 😜.

Notepadqq is available on Linux and is a pretty good replacement

It can indeed, but Notepad++ is explicitly Windows only.

There are some clones for Unixlike platforms, and I guess you could run the genuine article in Wine if you really felt like it. But don't go looking for an official Linux build, because there isn't one.

Thank you for mentioning Sublime Text! It seems to be a very competent text editor. However, unfortunately, I don't like how it is not open source.

I think my needs for a text editor for making notes and/or writing texts are mostly fulfilled between Emacs and Kate. At least..., for my untrained eyes. Do you think Sublime Text offers merit beyond (either of) these to be considered instead?

Thank you so much! The instructions will be very helpful whenever I test out Zed later today or early tomorrow.

Sorry for the late response.

I've tested most of what has been suggested and I can attest that Kate is indeed very good. Thanks for mentioning your endorsement as well!

However, while I really like Geany aesthetically, I wasn't able to fold Markdown headings with it. Uhmm..., would you happen to know if this is actually featured?

Yeah it seems folding with markdown isn't as ubiquitous as I'd like. I've tested a couple text editors since yesterday and only Kate (and (by extension) KDevelop) did a decent job at supporting folding with markdown.

JetBrains IDEs

I have used them in the past. They're definitely pretty cool and do their job well. Unfortunately, unless I'm wrong, most of their offerings^[Don't quote me on this, but I believe their open source options are limited to the community editions of IntelliJ IDEA and PyCharm. Which isn't too bad as both of them should support a plethora of languages (including Markdown).] are not open source. I believe this also applies to Fleet.

My apologies for not making it clear in the post, but I do prefer open source whenever I can afford it.

Finally, there's a lot not to like about electron, but I feel like JetBrains' use of JVMs isn't a lot better.

Regardless, I will note it down as I intend to test them all out anyways :P .

Please feel free to correct me if I'm wrong in any of the above. Thank you!

Sorry, I don't understand. It seems others have already recommended text editors that probably fit the bill.

Perhaps my post was unclear or causing confusion? If so, please allow me to correct myself.
