==Welcome to Vesper's Scratchspace~==

'''Today's menu:''' [https://wiki.mozilla.org/Labs/Ubiquity Ubiquity] URL noun type (and a basic function that uses it)

The regex in the code more or less says this:

 (some protocol name) :// (a string) [. (a string)] [/ (a string)] (maybe / if you want)

Items in square brackets can be repeated. So,

 pasta://a.taste.from.little.italy

is a valid url, according to this model. And, so is this:

 universe://milky.way/earth/north-america/canada/ontario/

All of these choices were arbitrarily chosen by me. I'll be pursuing the community for a better description of what a URL should and should not be.


'''The code itself:'''
 
 var noun_type_url = {
   _name: "Valid URL",
 
   suggest: function( text, html ) {
     if (!text)
       return [ CmdUtils.makeSugg("http://") ];
 
 
     if(/^[A-Za-z0-9]+:\/\/([A-Za-z0-9_-]+)(\.([A-Za-z0-9_-]+))*(\/([A-Za-z0-9_-~#=]*))*(\/[A-Za-z0-9_]*\.[A-Za-z0-9_]+)?$/.test(text)){
       return [ CmdUtils.makeSugg(text) ];
     }
 
     return [ CmdUtils.makeSugg("http://" + text) ];
   }
 };
 
 
 CmdUtils.CreateCommand({
   name: "url",
   takes: {"your shout": noun_type_url},
   preview: function( pblock, theShout ) {
     pblock.innerHTML = "Will verify: " + theShout.text;
   },
   execute: function( theShout ) {
     var msg = theShout.text;
     displayMessage( msg );
   }
 })

My apologies to those with screens that aren't 1280 pixels wide, but the regex doesn't like to be split into multiple lines.


'''Known issues:'''

It can't handle the "?" in PHP querries. I assume there can only be one, and it must be after the filename (with the extension). Hashes (#) should probably be handled the same way, instead of the way I'm handling them now (as letters, allowed anywhere except in the domain).

Syntax for the sample command was edited from the sample "echo" command in the [https://wiki.mozilla.org/Labs/Ubiquity/Ubiquity_0.1_Author_Tutorial tutorial].
