Setting `RelativeURLs` to `true` will make all relative URLs in the site *really* relative. And will do so with speed. So: In `/post/myblogpost.html`: `/mycss.css` becomes `../mycss.css` The same in `/index.html` will become: `./mycss.css` etc. Note that absolute URLs will not be touched (either external resources, or URLs constructed with `BaseURL`). The speediness is about the same as before: ``` benchmark old ns/op new ns/op delta BenchmarkAbsURL 17462 18164 +4.02% BenchmarkAbsURLSrcset 18842 19632 +4.19% BenchmarkXMLAbsURLSrcset 18643 19313 +3.59% BenchmarkXMLAbsURL 9283 9656 +4.02% benchmark old allocs new allocs delta BenchmarkAbsURL 24 28 +16.67% BenchmarkAbsURLSrcset 29 32 +10.34% BenchmarkXMLAbsURLSrcset 27 30 +11.11% BenchmarkXMLAbsURL 12 14 +16.67% benchmark old bytes new bytes delta BenchmarkAbsURL 3154 3404 +7.93% BenchmarkAbsURLSrcset 2376 2573 +8.29% BenchmarkXMLAbsURLSrcset 2569 2763 +7.55% BenchmarkXMLAbsURL 1888 1998 +5.83% ``` Fixes #1104 Fixes #622 Fixes #937 Fixes #157
