which is exactly what i want in a text editor. If i need the IDE features, i'd switch over to vscode, or use intellij. For quick text editing work, like changing a config file or something, this is perfect.

I don't enjoy vscode (any more) and don't enjoy IntelliJ, so I'd hope to be able to use this for IDE things.

I'd like to see an alternative to LSP created for editors like this, now that Visual Studio Code has shown not to be open. I think it could be built upon Jupyter Kernels, which really pioneered the client server architecture of LSP.

My ideal IDE would be something I would also want to use for one-off editing of config files. I did this with TextMate back in the day.

Your conflating LSP and VSCode. LSP is a completely open spec for things like autocomplete, syntax highlighting, symbol searching and so on. Any editor can use any LSP server and jetbrains is using it for new languages in their editors and fleet

VSCode is also completely open source. The only thing not "open" about it is the keys they use to make the final distributable. Even the VSCodium docs say as much. They literally just build the final distribution but with slightly different keys to point to their open source extension distribution website instead of the Microsoft one

On a surface level, this is true. Vast majority of the code that makes VS Code is MIT licensed.

But the configuration of what marketplace is used and what extensions have access to the privileged "proposed API" makes huge difference in what Microsoft/GitHub can provide as user experience and what other developers can do.

See this great post for detailed explanation how Microsoft created a closed ecosystem around VS Code https://news.ycombinator.com/item?id=32657709

I understand the difference in UX but I'm really not concerned with that. The code itself is all open source for the VSCode client and will probably remain that way. Extensions like Pylance are replaceable and the Python extension can already just use Jedi instead. Also I'm sorry but that article is really terrible in terms of both content and layout. In terms of content, its only real argument is the .Net fiasco and some issue with Gitpod that really doesn't matter. In terms of content, the page is utterly unreadable

I'm perfectly aware of what Microsoft could do in some distant future. But as is, for all intents and purposes, VSCode is open source

... Except that if you use the source to make your own build, you lose the extension ecosystem that is one of VSC's major selling points. It is at best a worked example of tivoization.

The extensions are compatible, aren't they?

    rm -fr ~/.vscode/*
    cp -a ~/.vscode-oss/* ~/.vscode/
    # Run VS Code, download extensions
    cp -a ~/.vscode/* ~/.vscode-oss/

Based on my recollection of migrating to VSCodium, all my extensions continued to work just fine.

I think there's also a hacky way to let VSCodium access the VS Code extension marketplace, but I believe it's an EULA violation.

You can easily just download the extension dist files and dump it in the extensions folder. Most extensions are open source too and VScode is not doing anything special with the extension files. They're mostly just JS. You lose out on the convenience of the marketplace but the open source version exists. If a maintainer doesn't have their extension on there, usually reaching out to them will have them upload it there too or as I mentioned, just clone the repo

geany works well too

If you want "Open Source Sublime" check out CudaText. Loads fast too. Plugins are Python (like Sublime Text) but whole thing is coded in FreePascal using Lazarus. It's really capable.

After reading your comment, I tried to setup a CudaText + LSP Plugin + Intelephense as I mainly develop in PHP. Unfortunately, my experience of LSP on CudaText is not as good as Lite XL.

Also, looking at its repository, CudaText currently only has 1 active contributor, which is a little worrying if I want to use it as my main text editor. I hope the community around CudaText become bigger because I think the concept is good, and I really hope CudaText can be on par with Sublime Text.
