You can reach https://dlang.org/library/std/regex.html and https://dlang.org/library/std/regex/replace_all.html via Google ("dlang" "replaceAll"). When you do, you will reach a site that nominally works, but has for instance a broken anchor link to https://dlang.org/library/std/regex/replace_all.html#Replace%20format%20string , because the std.regex docs expect to be on a single generated html site. https://dlang.org/library/ should probably redirect to the corresponding https://dlang.org/phobos/ page.
