There are some subtle differences between it and Visual Studio Code. The main one is the not having access to the VisualStudio market place. The C/C++ template isn’t there but instead is installed by default.

However I have found that the tasks and launch json files created from the F1 menu don’t have the C++ choices. What this means is that you have to get them from an official Visual Studio source, like Visual Studio Code installed on 64-bit Windows/Ubuntu/Mac.

I’d already done this so I used WinSCP to send them via ssh from my Windows box to the Pi. It’s a slight irritation but once you’ve got them setup it works ok. I can build applications haven’t got debugging working yet though.

There is an alternate Extensions Marketplace which has 266 items in it.  That’s a screenshot of the programming language extensions.

It was very easy.  This was onto my Pi 4 running 64-bit Raspberry Pi OS.

Go to the releases page on the vsCodium website, it’s on GitHub.  If you are running 32-bit Pi OS then you need the codium_1.46.0-1591900344_armhf.deb file (the number will most likely have changed).  For the 64-bit one, you need the codium_1.46.0-1591900344_arm64.deb.

When you click on the link it will download and ask if you want to keep it. It will then give you the option of opening it and select the archiver. That will install it for you.

After that, to run it from the command line just type codium.

Or as I just discovered. Look on the pull down menu, go onto accessories and you should see (probably near the bottom) VSCodium. Move the mouse over and right-click.You’ll see a popup menu with Add to Desktop and Properties. If you click the former, you get an icon on your desktop.

Screenshots were captured with the Flameshot utility. It’s installed with sudo apt install flameshot. That’s the VSCodium and Flameshot icons.

As they say “This is not a fork. This is a repository of scripts to automatically build Microsoft’s vscode repository into freely-licensed binaries with a community-driven default configuration.”

Microsoft’s code includes telemetry and tracking code. The code built here is the same as Microsoft’s but with that telemetry and tracking code removed. Also it includes builds for both ARM (32 and 64-bit) which you don’t get from Microsoft.

The Docs page provides info on how to copy JSON bindings from Visual Studio Code to VSCodium. I shall be giving this a try. Much as I like the code.headmelted.com Visual Studio Code, it doesn’t appear to be updated very often whereas VSCodium seems to be built every night.
