I think I disagree. The bnf you are quoting form is from “For example, some URI schemes do not allow an <authority> component, and others do not use a <query> component.”
The http scheme requires the //. And since the return struct from URL.parse() has fields like “host”, it implies it has semantic understanding, otherwise the only result possible scheme, andtherest… with no parsing of other. The previous email I sent had a reference to the common format of many “scheme”s using the authority… but this is not required. > On Feb 21, 2025, at 12:04 AM, 'Dan Kortschak' via golang-nuts > <golang-nuts@googlegroups.com> wrote: > > On Thu, 2025-02-20 at 23:38 -0600, robert engels wrote: >> Also, see https://datatracker.ietf.org/doc/html/rfc2396#section-3 for >> more details on the scheme + authority. > > > The BNF is (including only the parts that are necessary to show > validity): > > absoluteURI = scheme ":" ( hier_part | opaque_part ) > hier_part = ( net_path | abs_path ) [ "?" query ] > abs_path = "/" path_segments > path_segments = segment *( "/" segment ) > segment = *pchar *( ";" param ) > param = *pchar > pchar = unreserved | escaped | > ":" | "@" | "&" | "=" | "+" | "$" | "," > > The original URI (I miswrote URL for URI in my last post — the > url.Parse documentation notes "technically, a URI reference") was > "http:/127.0.0.1/index.html" which can be broken into: > > scheme = http > abs_path = /127.0.0.1/index.html > > The url.Parse function doesn't examine semantics, that's the caller's > responsibility.
