Conditional include based on OS

• Dotter version: 0.13.0

The question

Since I have the same hostname on Windows and WSL, I'm trying to work out how to conditionally include the windows.toml only when running in Windows. This would be the first step in having it only install the Windows Terminal configuration files when run from Windows and ignore it when from any WSL2 distro.

I've tried using the following in the hostname toml file, and it didn't work, as it doesn't seem to like templating at that level. Any suggestions?

{{#if (eq dotter.os windows)}}includes = [".dotter/windows.toml"]{{/if}}
packages = ["windowsterminalpreview"]
