Is there anyway to make var for @version from local and remote ?

So you can see the "real" version number instead av the version number that its getting now.

Thanks for the code btw !

I don't know of a way to get any meta-data for the local copy of the script; however, Greasemonkey probably has a way to do it by now.

the local version can you just add a variable manually. dont you know about getting the remote "real" version number ?

hm, how to creating a var from the version on the site.

for example if you take my script http://userscripts.org/scripts/show/56716, in the code i got the meta-data "@version".

var localver = "1.2.4.1.1"; //this value can I change manually every time I update the script
var remotever = ? //this value should be the value you can find on the script page, in the upper left corner "Version: 1.2.4.1.1" (it's from the metadata @version in the latest code).

so i can get this to work I can just be using a message when a new version is out, like;
("I new version is out: "+remotever+". Your current version is: "+localver+". Wanna download new one?");

My english is not the best, hope you get what I meant.

You'd have to parse it out of the meta.js file for that script. Probably something like this (I haven't tested this, so there might be some syntax errors):

var script_number=56716;

try
{
	GM_xmlhttpRequest(
	{
		method: 'GET',
		url: 'http://userscripts.org/scripts/source/'+ script_number +'.meta.js?'+new Date().getTime(),
		headers: {'Cache-Control': 'no-cache'},
		onload: function(resp)
		{
			var remote_version;
			
			remote_version=parseInt(/@version\s*(.*?)\s*$/m.exec(resp.responseText)[1]);
			alert('Remote version is: '+ remote_version);
		}
	});
}
catch (err)
{
	alert('An error occurred while checking the version:\n'+ err);
}

also check out the metadata block info on http://wiki.greasespot.net/Metadata_block. This has a very good example on parsing metadata for local and remote scripts! :)
I found a problem though when parsing remote meta data I had to make a minor modification.
from 

  for each (line in lines) {

to 
  var i=0;
  for each (line in lines) {
    if (++i > lines.length) break; // to control error in looping from remote responses

because the loop was continuing even after reaching the last element... don't know why.

Ah, thanks. I figured there was a way to get the local metadata; I just didn't know what it was.
