Jetbrains Tools
Various JetBrains IDEs and tools are available from nixpkgs under the `jetbrains`. For instance, CLion is available as the`jetbrains.clion` package.
Plugins
Some Jetbrains IDE plugins such as Github Copilot need to be patched in order to work on NixOS.
At the time of writing, plugin support is not available in the latest stable version of Nixpkgs (23.05). To install a package from nixos-unstable, see [1].
For example, a package of CLion with the Github Copilot plugin pre-installed can be obtained by adding the following line to your package list:
(pkgs.jetbrains.plugins.addPlugins pkgs.jetbrains.clion ["github-copilot"])
where pkgs is a suitable version of nixpkgs.
Note that Jetbrains IDEs tend to manage their configuration and plugins statefully. For example, if you have previously attempted to install Copilot through the IDE's plugin manager, you may need to delete the IDE's state in as described in [2].
