<div dir="ltr"><div><div><div><div><div>A protocol is simply a semi-standard way of using an application. </div>For instance, when you set the EDITOR environment variable, the expectation is that the command in EDITOR will accept at zero or one filenames after it. </div>So: `$EDITOR my_file.txt` </div>I'd consider that a "protocol". It's undocumented and mostly ad-hoc (UNIX philosophy at its finest), but lots of programs support launching `$EDITOR`, and lots of programs support being set as `$EDITOR`. </div>If I make a "default browser selector" widget, there better be a way of telling the browser how to launch a specific webpage, since the whole point of a "default browser" is to let me select what happens when I click on a very specific webpage. Yes, web browsers don't *have* to have that functionality, but they shouldn't be able to be selected as a "default browser". So, I'm skeptical of the value or utility of the user selecting one of many "IRC Client"s from a list without any guarantee about what the program even does. So, what's the goal of building a list of IRC Clients? What will the user do with this list that's good for them? </div></div><div class="gmail_extra"> <div class="gmail_quote">On Tue, Jan 7, 2014 at 11:51 AM, Jerome Leclanche <<a href="mailto:adys.wh@gmail.com" target="_blank">adys.wh@gmail.com</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div class="im">On Tue, Jan 7, 2014 at 4:00 PM, Jasper St. Pierre <<a href="mailto:jstpierre@mecheye.net">jstpierre@mecheye.net</a>> wrote: > What's the use case you imagine where the user would want to choose from a > list of IRC clients, without the list actually able to launch the IRC client > in question with a specific server/channel? </div>We've been through this. <div class="im"> > > It seems quite backwards to have a way to say "this app supports this > API/protocol" with the app actually not being able to support that > API/protocol.

A web browser can be a web browser without ever accepting http uris as argument. IM clients themselves are much, much less likely to accept protocol URIs, especially since some of the protocols they support simply don't have special URIs, and just because xmpp does doesn't mean that it makes sense to accept it as a URI. Furthermore I have no idea what you mean by "gaining support for my protocol". You are conflating protocols and URIs. J.
