ide-flatpak-wrapper VS com.vscodium.codium

For a lot of programming languages, there's a Flatpak extension that adds the relevant tools. Just search for "Freedesktop SDK" and look in the extensions section. They'll be installed under /usr/lib/sdk. There's usually an enable.sh script that if you source it adds all the necessary env vars, or most IDEs come with ide-flatpak-wrapper which you can configure to auto-enable certain extensions

Also, you can just use FLATPAK_ENABLE_SDK_EXT=* to enable all extensions, since that's usually what you'll want. Here's the repository for that entrypoint script: https://github.com/flathub/ide-flatpak-wrapper. It's the wrapper submodule in VSCodium's repository, because it's shared between VSCode and VSCodium and possibly others. You can check the vscode.sh file on that repo if you want to understand what it's doing.

yeah, that'd be crazy... especially, when there's a flatpak and an appimage if they really didn't want to add the repo..

I use Vs Codium, works just the same but without all the Microsoft telemetry. You could use the flatpak in the software manager, but I got lazy filter things with FLatseal.

I wouldn't spend too much time worrying about privacy in open-source editors. From a privacy perspective, being built on Electron isn't different from being programmed in C++ or anything else - they can still spy on you and do network requests. I'm not a fan of vscodium myself, but it sounds fine for your needs. You could run the editor in a sandbox that blocks network traffic. On Linux, this is easily done with the Flatpak and Flatseal.

I'm following the Vscodium instructions to get more languages in its flatpak (namely, Php). But it seems that flatpak doesn't detect my installed php sdk.

VSCodium is a very, very, popular package. An Issue tells them that they shouldnt break the sandbox themselves by writing into the home dir.
