Linux

Idk if it counts as less popular, but I always thought Sublime got too much flak. The popups are annoying, but other than that it's a great editor imo. It doesn't have the bells and whistles of something like VSCode or a full IDE, but that's also why I like it, it's much more snappy and lightweight. And you can still get things like LSP working so for me at least it gives me everything I look for in an editor. I even decided to pay for a license a few years back, considering I make my salary with this thing the cost is negligible.

I've been using Lapce for a bit and it's pretty cool, like VSCode but written in Rust. It's actually so much faster, like you press a key and there's instantly autocomplete suggestions and error warnings, so it feels a lot more responsive than VSCode. It also opens faster. There's still a couple weird things and missing functionality though because it's early in development so I'll probably go back to VSCode for now.

I use Pulsar for working on my many JavaScript projects. It's a FOSS, community-maintained replacement for the canceled Atom text editor.

I'll give you six that I haven't seen mentioned yet:

• sim and vis, both of which focus on combining vim motions with structural regular expressions as used in...

• sam and acme from Plan 9, both of which are included in Plan 9 from User Space (aka plan9port). sam also has a modified/expanded version in the form of deadpixi/sam, while acme has spin-offs like a port to Go and a standalone version.

• mg, one of the three default text editors included with OpenBSD (the others being vi and ed).

• sandy, the abandoned suckless text editor. It uses dmenu and is fun to mess with for shits and giggles.

Emacs. Everything.

Helix

I'd describe it as "NeoVim for people who don't want to spend time configuring it". It has syntax highlighting (for pretty much any language you can think of) and LSP support out of the box. And the config file is just a TOML file. Here's my current config for example:

theme = "monokai_pro_spectrum"

[editor]
line-number = "relative"
middle-click-paste = false

[editor.statusline]
mode.normal = "NORMAL"
mode.insert = "INSERT"
mode.select = "SELECT"

That's it. No need to deal with Lua or VimScript

Also using commands after typing the : is easier than in NeoVim since Helix will show you a list of available commands and a description of the closest match (or the one you choose from the list with the tab key). It looks like this:

I use Helix for quickly editing files and coding
