Nov 16, 2008 8:29am JoeSimmons Scriptwright	Think you could combine Prevent Autoplay and this script? I would love it.

Nov 16, 2008 6:10am Avindra V.G. Script's Author	yeah, but sometimes, YouTube will "think" there's not HQ video available, even though there is one, so I have to include the xmlhttprequest as a backup.

Nov 16, 2008 6:00am Yansky Scriptwright	@avg, if you use this hack, you could probably avoid using an GM_xmlhttpRequest. - http://www.kottke.org/08/11/high-quality-youtub...

Nov 8, 2008 10:44pm Compass User	Great Script! There's this firefox addon called GoogleTube, where u can load youtube videos within a google search (without having to load up the page in a new tab) Is there any way to tweak ur script so that when playing YouTube vids off Google it uses the high quality vid instead of the normal one? Thanks

Nov 3, 2008 6:00am Avindra V.G. Script's Author	sure, i'll work on it when i have some time. by the way, you'd look for `#hq-link` instead, so you can use `$('hq-link')` to see if the link is there.

Nov 2, 2008 11:18pm Cleanlyness Scriptwright	Can you make it so YouTube profile videos display in high quality also? (example: www.youtube.com/CBS) The YT CSS uses this. `.profile-hq-links{ text-align: right; margin-top: 4px; margin-bottom: -6px; color: blue; font-size: 11px; font-weight: bold;width: 478px; cursor: pointer; cursor: hand; }`

Oct 31, 2008 11:49pm Avindra V.G. Script's Author	the cookies probably have an expiry date. (they have that ability unfortunately)

Oct 31, 2008 10:11pm scriptnoob User	i'm using this script because youtube doesn't save my setting! why does it not save my setting? i set my preference to high quality and it works for a few days but eventually resets. i have cookies enabled. using firefox 3. i'm not clearing my cookies either.

Oct 3, 2008 5:16am JoeSimmons Scriptwright	Yeah dkhal, that does create an image from a string, so the browser doesn't have to connect to a site to get it. And about the former comments... The best way to get var1 is to use avg's method, just put a slash before the & though, like `/\d+(?=\&var2)/`, but the best way to get var2 (if the number is at the end of the url) is `/\d+$/`.

Sep 30, 2008 10:04am dkhal Scriptwright	thanks that's quite helpful i think now i know all the things i need to code scripts and if i had anymore problems later i will consult you for help :)

Sep 29, 2008 11:09am dkhal Scriptwright	one more thing but not about regexp i hope i'm not being too "pushy" lol can you explain what this is? background-image:url('data:image/gif;base64,R0lGODlhLwAwAJEAAPHp2vHr3PHm1/Hs3SH5BAAAAAAALAAAAAAvADAAAAL/nB2TFwECo5ygMWtATZX58VDaqEGhoHGA4jQnurlvd9S1I5VCgkfOS8HYhpfJDkFUGFeIhZP3PLxYtAsowuQxRqaUZxFaYIVXlLVnzEGl2AkyAHEigN00zdmOKAwQG9ocBgeoZrPEE1dIobQjyGHk51a20pCAdaL1ZalHWXYk4YHFx5jU0Ne5J4oiKGDzIqTShaowk5jTtKo3l6Z6YMTZadqrivgHE7TYU9sHxVtDyxZ682BR6VNjiZCHWn2ZcXJjzWI7YA036Xho6oqnCgYzGXaNB87LlYXDtPgWPtvhlU1M1IIrWeKlMoHpxqxIi2g8yHdikh1Ze+gcichmYLeH/+Dm0DjCRqIJBiA7OcrHx6OYVmZW5YOj0RrHaypTOmsZTUlMRDOz1QQxkOAiM9kghsJ1VKFFRyMzEO0x8FjQN0BINuspaB8ij/0GrsK0lSCGhxoWliQ3z6q/EvcMlopWriW6oU59sDuLbWggJCbC6WBldZm4KnWbFia6ZVQ1fuSGHSn2FyGyEMqevv2ky07UCb/osBzjQUdZr7hQNn7Et2mcqUUAf9sMMsS5xX8T7nH52kK3dFOXIGsELBjApmIAJw4VaOSM3gyLyzErQjOSoYSgveRhUerOyPc6ZZH1Q/a/23XFpAiKFDEGas+FTFmDPXu7JKTSIyFhidKP6vSh9xs1vtwHqNhBAhcoBEEMWXcQgd0uu6SwloADFAAAOw==') i know what the CSS part is just usually i use URL in the second part of the CSS just this is something unusual to me i think its a code to make firefox create an image coz it doesnt require a connection to the internet to work so it must be local so is that it? and if so what language is it and how can i something like it? if you heard of a manual for that it would be perfect

Sep 27, 2008 3:36pm dkhal Scriptwright	no here is fine i just want to be informed in some way that you replied (it would be better if they did some sort of inbox here) thanks a bunch thats all i need and i'm gonna use every bit you tought me in my newest updates i couldnt have done it without you i mean it i really appreciate it and the same goes to Joe who has been next to me from my first start in userscripts i will keep in touch with you guys and hopefully i won't have any more problems lol email would be better thanks again

Sep 27, 2008 3:14pm Avindra V.G. Script's Author	ah see someone would tell you use use .split("&") or something, but you'd have to do a couple of splits, arrays, and possibly substrings. this regex formula: /\d+(?=&var2)/ should do the trick on the example you provided for finding the value of var1. `?=` is negative lookahead, meaning it will stop when it finds that, but it won't include that in the search. for the second number, you can do: /var2=\d+/ // then after you have the matched string, run a : // .replace("var2=","") Unfortunately, positive lookbehind isn't supported natively in javascript, so you just have to trim off what you don't want afterwards. for not matching just numbers..... /var2=.+(?=&)?/ // then after you have the matched string, run a : // .replace("var2=","") As for the dollar-sign... that matches the end of a line, and in URLs there's only one line so I can't see how that's relevant. FOR mimicking positive lookbehind's effects without treating match afterwards ALSO, I've tried this:, "page.php?var1=1456&var2=8941436".match(/var2=(.+)?(?=&)?/) and using the second part of the array, you get the match you need, only the number. So: "page.php?var1=1456&var2=8941436".match(/var2=(.+)?(?=&)?/)[1] successfully returns what you're looking for. If you need anymore help, please email me instead lol. It's aavindraa@gmail.com.

Sep 27, 2008 6:03am dkhal Scriptwright	ok that worked quite fine so thanks for both your support but actually the real page i need the script in has an address like this URL = "page.php?var1=1456&var2=8941436"; for ex how can i get 1st number apart and 2nd nbr apart too in the simplest way (with using subtr and indexOf if possible) thats my problem i saw a method somewhere its by matching `/var1=\d+/` and inserting a $ somewhere to perform a match on that number only

Sep 27, 2008 12:41am Avindra V.G. Script's Author	Joe is right, you can use: /\d+/ or /[0-9]+/ Those are your two best choices; i prefer the first.

Sep 26, 2008 11:38pm JoeSimmons Scriptwright	var S = "page.php?var=1456"; var num = S.match(/\d+/);

Sep 26, 2008 3:50pm dkhal Scriptwright	one more quest if you have a string S="page.php?var=1456"; i want to get the 1456 using regexp i'm trying to use this but it doesnt give me the number only num=S.match(/\w+.w+\?var=/); i know i'm missing smthing in the exp so can you help me out and post it on my Youtube script thx

Sep 14, 2008 4:29am JoeSimmons Scriptwright	Yeah that's perfect.

Sep 13, 2008 8:07pm Avindra V.G. Script's Author	hey joe, i changed the links to be found with xpath. is that the best xpath "formula" to use? thanks.

Sep 13, 2008 3:11pm JoeSimmons Scriptwright	Cool. but I still think you're being very stubborn about the script source.

Sep 12, 2008 5:21pm Avindra V.G. Script's Author	Ok, but I will compress my scripts regardless :P but about your previous problem with some videos not working, could you please update to this version and see if it works now? it works on my end. This is the video that wasn't working for you.

Sep 12, 2008 4:40pm JoeSimmons Scriptwright	Compressing this script serves no purpose. Dial-up can even download the un-compressed source in one second.

Sep 12, 2008 2:53am Avindra V.G. Script's Author	this will sum up to 0.0001s (0.1ms) for skipping over all comments and whitespace. That's good enough for me ;)

Sep 11, 2008 3:08am prof7bit Scriptwright	@avg: The compiler, in its very first step of scanning the source code, will execute a loop where it reads from beginning to end character for character and compare it to what it is expecting next (what the syntax and grammar of the language will allow there to be next). If it is inside a comment started with // it will only have to look for the next newline. It will loop and read the next characher and compare it just to [\r\|\n] and nothing else until it finds one. This loop is written in C++ and compiled to optimized machine code. I would roughly estimate a maximum of 20 clock cycles per character for this loop, outside of a comment it will be a lot more work because more possible options exist and some things have to be stored and compared with each other and a syntax tree has to be built, but inside comments (and whitespace) it can go very fast from character to character. If we assume a file with 10k worth of comments and whitespace on a 2GHz Machine this will sum up to 0.0001s (0.1ms) for skipping over all comments and whitespace. This is about the time it takes for your 70Hz CRT monitor to draw 7 (seven) of it's 1024 lines. The removing of this huge ammount whitespace could happen 1000 (thousand) times in a row within one twinkle of the eye (100ms). This all has to be done only once. After scanning, parsing and compiling to bytecode it will then finally be executed by SpiderMonkey, mozilla's JavaScript virtual machine. The only reason for "compressing" scripts this way is when you serve big scripts via slow internet connections (and even here the better solution would be serving it gzipped instead of plain), but slow connections are obviously not the case here. Firefox itself is full of tons of javascript that drive it's user interface and none of it is "compressed" this way.
