It looks like Resource.RelPermalink publishes the resource to /public, but I don’t want to do that because the resource isn’t fully processed. I don’t see anything like .Path in Resource methods.
Context:
I’m executing a resource as a template and putting the result next to the original resource (same nested directory hierarchy), e.g.
Input: assets/css/theme/mycss.css
Output: public/css/theme/mycss.ac6c302f8221a01b05fa6c351c83a274bf4e173b.css
The file is then processed by fingerprint, minify, etc.
