== Intellij Idea and Rust, launching from terminal. ==

I seem to be having success by using nix develop, flakes and launching Intellij from the terminal. Launching this way lets me capture the environment variables of my development environment. I used to get errors when doing this but I found the key is to export an XDG environment variable in the shellHook. I also use a shellAlias to launch idea with the command "@idea". This requires a .XDG folder be added to the development environment for the XDG_DATA_HOME. There are three other XDG variables that may need to be similarly exported too and folders created. But this one is the only one I have identified that is definitely problematic.

environment.shellAliases = {

"@idea" = "idea-community </dev/null &>/dev/null &; echo 'Launching Intellij idea-community'"; # launch idea from the command line. This let's it access the environment variables in the 'nix develop' shell environment.

};

I combine that with:

allows one to automatically enter nix develop shell:

direnv = {

enable = true;

nix-direnv.enable = true;

};

a .envrc file with the following two lines:

strict_env

use flake

I then modify the basic rust-overlay flake found here:

https://github.com/oxalica/rust-overlay#use-in-devshell-for-nix-develop

The key is to add:

shellHook = '''''''

export XDG_DATA_HOME="$PWD/.XDG/share"

''''''';

The XDG_DATA_HOME variable export avoids the following error message from Intellij Idea:
