Vscodium

For anyone that used Atom, check out

Fuck microsoft

I've been keeping a list of alternatives for a while now that I really like:

• Pulsar - An actively developed fork of Atom once Microsoft killed it off. Disclosure: I'm on the Pulsar team so I'm more than a little biased here but if you want to get involved we are always after people who want to contribute and we have a very friendly and active Discord server. First thing we did was re-implement the package backend and migrate it so we were able to keep the thousands and thousands of community packages for download.
• Lite-XL - A really lightweight and fast editor written in C and Lua that is very actively developed. I use this on some less powerful systems.
• Lapce - Another lightweight and very fast editor written in Rust and is in the middle of moving to their own UI framework. Not that extensible at the moment but supports LSP plugins.

Then for terminal based editors I really like Helix which is vim-like but uses a selection -> action model (like Kakoune). I really like it because it requires almost no configuration.

VSCodium. Basically ungoogled-chromium but VS Code and Microsoft.

Lunarvim

You could try VSCodium. VS code but less spyware-y

I wouldn't exchange my neovim config for anything. After getting used to how vim works and installing all the plugins I need, I feel like this is my favourite editor. It looks nice and I enjoy using keyboard shortcuts over using a mouse.

That said, the day I lose my neovim config is the day I die. If it disappears I'm doomed

Maybe codium will be what your looking for

People are writing different opinions, but you are right, best IDEs are comercial software.

I think it is just because it takes a lot of time and effort on boring stuff to make this tools smooth. Generally in open source we work on fun parts and leave those boring last 20% unfinished, which is ok with me.l

Lapce is an alternative that you can try, though it's self-described as "pre-alpha".

I have VSCodium installed via flatpak. Works perfectly.

Edit: has open-source extensions too.

Neovim + LunarVim is most of what I need for software engineering out of the box. It even has debugger support. Plus it's way faster than VSCode and terminal friendly.

Vscodium or Geany

My first comment would be that free software made by a corporation is still free software. Like Eclipse, which was originally made by IBM and is a huge ecosystem, especially for "java and friends." So, there is nothing wrong with VS Code(ium). It is a "proper" open source editor and a very good one (I don't use it though - I prefer EMACS).

As for community-base alternatives (which is probably what you mean), you could consider kdevelop or pulsar. There are other alternatives which are equally good and surely one of them will fit your purpose. You mentioned Kate and I can't find anything wrong with it, especially once you start installing the plugins that are relevant to what you do. Same with Gedit.

I heard good things about Geany.

If you like Kate you can try Kdevelop. It's the same editor base but a bit more IDE like

I use VSCode myself nowadays, but I have some colleagues who prefer Qt Creator for C++ development (our builds are based on CMake and GCC/CLang). It is open source and not tied to developing with the Qt framework.

I don't understand the meaning of "visual editor" in the context of "text editor". But i can tell you, that i am a happy user of Spacemacs, a distribution of GNU Emacs. Doom Emacs seems also to be pretty popular. One of my favorite emacs packages is the git client "magit": https://video.emacs.ch/w/kFF1N8kveg3eCx86tU6aMW

Visual Studio Code is kinda heavy, so why not Netbeans or Eclipse?

If you program in Python check out Spyder, some other languages also have specialized IDEs that can be really good.

i just use vim for everything except debugging, and vscode for debugging

I alternate between VCCodium and Kate, both are fine to me, but Kate feels snappier since I'm on KDE. It's also less of a resource drain.
