Topic: Script development / Namespace is not working?

Thanks -- I remember reading that but I guess I forgot. Too bad the namespace does not work for this reason too.

Topic: Script development / Namespace is not working?

I need to have my users update my script every time I release a new one, so I created an auto-updater. It works fine, but my only problem now is it creates a new userscript when I install the new one.

I think I am using the namespace right, can anyone see what's wrong? This is the metadata for my older and newer version:

Old version:

// ==UserScript==
// @name Spogg Improvement Pack v1.3.0
// @namespace http://itsjareds.scienceontheweb.net/misc/sip/
// @version 1.3.0
// @author KnifeySpooney
// @description Adds features to the online community Spogg.
// @include http://*.spogg.com/*
// ==/UserScript==

New version:

// ==UserScript==
// @name Spogg Improvement Pack v1.3.1
// @namespace http://itsjareds.scienceontheweb.net/misc/sip/
// @version 1.3.1
// @author KnifeySpooney
// @description Adds features to the online community Spogg.
// @include http://*.spogg.com/*
// ==/UserScript==

And yes, both of the files are in http://itsjareds.scienceontheweb.net/misc/sip/ .

I love using this site for testing javascript regular expressions - http://www.regexpal.com

I had this problem so added a check to my script
if (window != window.top) return;

Thanks, it started happening again and that fixed it.

Topic: Script development / Scripts do everything twice

Are you running Firebug and is the console active for that site ? If yes, try disable console as FB can cause this "double load" behaviour.

Thanks, that seemed to do it.

Topic: Script development / Monitoring page JS?

You could put at the end of each script:
GM_log("Greasemonkey script [your script here] executed.");

Is this what you meant? If you have a lot of scripts installed, this may be a problem.

Topic: Script development / Writing to File

Not directly without making your script a FF extension. Otherwise, any web page could do this to you, and there's obviously security issues there.

Topic: Ideas and script requests / Set wmode="transparent" for flash players. Please.

Lol. Difference made.

Topic: Ideas and script requests / how to remove <meta bla bla bla > tag ??

To write it yourself, try this:

var metas = document.getElementsByTagName("meta");

for (var a=0; a<metas.length; a++) {
  if (metas[a].http-equiv.match(/refresh/))
    document.getElementsByTagName("head")[0].removeChild(metas[a]);
}

Not been tested, but should work. Someone please correct me if I'm wrong.

Topic: Script development / Getting headers of a script?

How can I get the headers of a script with a function inside the same script?

By headers I mean this text:

// ==UserScript==
// @name Blah
// @namespace Blah
// @description Blah
// @include Blah
// ==/UserScript==

I need to get some info called @version, how can I do this?

Edit: Also, I would like to know how to check if another script is installed. Thanks!

Topic: Script development / Scripts do everything twice

Could the script be running on two frames in the window?

Are you using FF3?

Topic: Script development / How to catch any error?

How can I catch an error and give custom feedback in the error console?

I know there is try and catch(), but how could I write it to, instead of stopping the complete script on an error, give an error message in the console about that one thing?

Topic: Script development / Scripts do everything twice

My scripts are doing everything twice.. I made sure by putting GM_log("this is a test") at the head of my script, and each time I load a page, that message comes up twice.

There aren't two of my scripts or anything, just one. I'm not sure if this is slowing it down or not. Does anyone else see this?

Topic: Script development / Getting previous node

I got it working using what gollum said, I was going to try that later but I had to run.

@RunningBlind: It is searching for any element with the class "mini", which was the <font></font> tag.

Thanks for the help everyone :)

Thanks also to gollum for the DOM Inspector.. will use often

var rel = document.getElementsByTagName("link");
for (var a=0; a < rel.length; a++) {
  if (rel[a].href == "the default href") {
    rel[a].href = "your url";
  }
}

Although I recommend you use Stylish (download link), it's another Firefox addon that edits stylesheets. You can change any CSS on a page with the !important option.

	var els = node.getElementsByTagName(tag);
	var elsLen = els.length;
	var pattern = new RegExp("(^|\\\\s)"+searchClass+"(\\\\s|$)");

I tested the regex using RegexPal, and the regular expressions are not the problem. And thanks for the blockquote help

I mean what znerp did, with the green? Or is that not a quote?

Topic: Script development / Help with smiley replacement?

Have you done some GM_log(...)'s to find if your getting what you expect from your regex expressions?

I did now that you told me to. It says that for every time it goes through the
for(var i = smileElements.snapshotlength - l; i >= 0; i--) part, it goes through the smileyRegex.lastIndex = 0; part twice.

What page are you testing this against?

Also, is there any way to do all the smilies at once, rather than the same function over and over?

I can't figure out how to incorporate that into my script. How could I change it to adding an image instead?
