Setting environmental variables for all applications launched in a gnome session

[doronbehar]

Back in the days I used a tiling WM, I was able to set environmental variables for all applications via ~/.xinitrc or other methods. With Gnome, this method does not work and I need to use systemd’s environment.d, as explained here:

How to set an environment variable when starting an application

There’s a neat trick with systemd (your case on Fedora), where you can create a file in your home directory and it will exported session wide. Create, for example: .config/environment.d/00-ardour-bug-8280.conf And inside just put the var you want: LV2_PATH=your-value Your GNOME Session should pick that up automatically on login, and all apps and processes will see it available. It works fine for me for a few apps.

However, my use case is a bit different and according to environment.d(5) I can’t use it because it doesn’t support shell commands. I would like to have the following variables set globally for my Gnome session:

export MPD_HOST="$(secret-tool lookup mpd-host localhost)@localhost"
export GITHUB_TOKEN="$(secret-tool lookup github-namespace doronbehar)"

Putting these lines in ~/.gnomerc doesn’t work, see this thread. For most purposes, I currently have these lines in my ~/.profile so at least my shell knows these vars. However, I have many more such calls to secret-tool for other env vars and I’d like to set them only once, to reduce my shell startup time.
