Atom was kinda revolutionary in its plugin support and everything IIRC.
Well, now that Atom has been replaced by VSCode, which is also an electron app, the original Atom devs, or at least some of them, are creating Zed. Zed's written in Rust and uses a lot less memory.
Of course it's not yet as mature and they're trying to earn money by integrating AI and selling that as a service. BUT the AI is voluntary and even if you do want to use it, you don't have to pay to use their AI (which comes with a free tier if you DO want to use it), you can literally run your own model in ollama.
It's not perfect, but I love how little RAM it uses compared to VSCode and (shudders) the Jetbrains suite (which I normally love, but hate the RAM and CPU usage, it can drive my computer pretty slow)
still have the patch they sent for people who published packages. I made a theme no one but me used but still! Pre microsoft github was cool
Got that patch still in it’s brown envelope somewhere in a drawer, for doing a syntax highlighting plugin.
They were indeed cool
It has become my favorite editor, even though I don't need or want the AI stuff. They do something that I do quite appreciate, that I wish other apps (looking at you, Firefox) would do:
In the AI section of the settings, the first thing is a toggle that turns off all AI features.
It shouldn't have AI features by default though. Just make that functionality a plugin that can be downloaded separately.
But companies like to make money default though.
They also developed their own Rust UI library and open-sourced it.
Didn't Sublime Text come before Atom?
it did, but this is about electron, which isn't relevant to sublime. sublime's plugins mechanism is a little different from atom, which is much more like emacs
Yes, but the plugin ecosystem really was pioneered by sublime and then ported over everywhere. A big reason atom was so successful is the plugin and themes were compatible.
I thought sublime text used textmate plug-ins at first?
Well maybe it did but I wasn't aware!

Historically I'd say Emacs plugin system predates atom and sublime, and was certainly as impressive in its flexibility.
That explains alot. I have both PyCharm and RustRover open as I ~~steal~~ convert stuff from a project I found. Anywho I was typing in discord and I was typing faster than it rendered and I thought that was strange
I've had PyCharm max out 3 or 4 CPU cores out of the 6 I have :/ I do have several million lines of code indexed by it though
