No it is not valid, RFC 3986 3.2. is pretty clear about it.<br/><br/>Worse, the net/http client will happily accept this kind of URL, defaulting to a local address but with an absolutely invalid Host header field set to &#34;:80&#34; in this example (see RFC 9110 7.2., the host is not optional).<br/><br/>As usual, developers do not read specifications. 2025-06-29T16:10:17Z https://yabu.me/nevent1qqsguecacfseawrcu40pjw2fzgkgzfrgn78ne99ez6w64jvgn94aj9szypc2q90alc98k8huve9d9ljdvhcylzxyk2q3kcd9rcp4tygsxenl282p4eh In reply to <a href='/nevent1qqs8wznvnfj0mdwanu6uxukhk3sfyr0nynrc880nytqfv7wf5nk8ars4k079s'>nevent1q…079s</a><br/>_________________________<br/><br/>DEFCUSTOM is for values customizable by the user. In modules, you have a lot of values which are not supposed to be customizable (e.g. regexps used by font-locks) but must be easy to redefine when you&#39;re working on the module. 2025-03-15T18:18:31Z https://yabu.me/nevent1qqsdywvmknwfjkyc3nyqam0ksvrmjzvka3eu78uyhzy7yqgrvpcvf8czypc2q90alc98k8huve9d9ljdvhcylzxyk2q3kcd9rcp4tygsxenl2l8wgyh Let us add DEFAPARAMETER to the long list of features #Emacs Lisp is missing compared to #CommonLisp. ELisp only has DEFVAR, which does not modify the binding if it already exists. Perfect to keep a state. But for a lot of top-level values, you want DEFPARAMETER, which creates or updates a binding.<br/><br/>Module development with DEFVAR only is really frustrating, forced to manually call SETQ each time you want to change a value. 2025-03-15T17:28:47Z
