Marking the content/ folder for your Hugo site as a “Source Root” in IntelliJ lets you use Path from Source Root to get the path to the file without the content/ prefix you don’t need when linking internally.

To make linking internally easier, I created an Alfred app snippet ({{< relref “{clipboard}” >}}), so now I only have to open the other post, double-tap shift, type “source root”, then run the snippet, and all linked up.
