radp

oh wow, code.google.com/p/chromium/issues/…

stars

Yi Jiang

@rchern Erm... do you get that if you click the "load more messages" manually?

rchern

no (:

Yi Jiang

@rchern Yeah, but that wasn't from the GM script so I thought it might be a existing bug in the chat js

Didn't notice it coincide with the /load command

rchern

2:14 PM

hm? i said your load command generates it (:

Yi Jiang

@rchern No, the Firefox console points to a random function is the chat js file

Error: c is not a function
Source File: sstatic.net/chat/Js/master-chat.js?v=e401b7dee435
Line: 197

rchern

running $("#getmore").click() in my console gives the error as well

Yi Jiang

@rchern Weird...

@rchern The error occurs after the loading is complete

And it doesn't appear in the Firebug console which is very weird

And Firefox literally hangs when the messages are loaded

rchern

...

did you test this before you pasted it into chat? hehe

Tim Stone

var v=c.data("source");if(v){q(v);return}}v=q;var z="/message/"+$(c).attr("id").replace("message-",""); seems off (in the actual chat script), or is there a normal data function I'm not aware of?

rchern

2:29 PM

api.jquery.com/data

Yi Jiang

@rchern Well, the error didn't appear in the Firebug console and doesn't appear to be part of the GM script, so no, I'm not entirely sure this is a problem with my script

Tim Stone

But they $(c) right after that, so I imagine c isn't a jQuery object.

rchern

well but you said it hangs your browser

Yi Jiang

@rchern So does clicking on the load new messages button manually

Chacha102

Hello

radp

2:33 PM

@rchern code.google.com/p/chromium/issues/…

rchern

@YiJiang, i don't see that getmore's click calls w(...)

@radp, didn't you already link to one that had been created?

radp

@rchern uh, no, the previous one was a completely unrelated issue on Chromium deciding web pages ending with .user.js must be UserScript pages even if they contain HTML

Yi Jiang

@rchern Sorry, what do you mean by that?

Tim Stone

I really wish that Firebug could clean up scripts so I could actually set useful breakpoints.

Yi Jiang

Also, I think there's no point in trying to debug obfuscated js

rchern

2:36 PM

@radp, but if they fix that won't it fix this?

radp

@rchern Possibly but not definitely.

rchern

@YiJiang i mean that the code you pasted regarding c.data("source") doesn't seem to be part of the code that $("#getmore").click() triggers? unless i'm missing a call

@radp, i'm not sure i see the urelatedness

Yi Jiang

@rchern It could be a callback that's been called after the loading is complete. Firebug's ignoring this error so I can't make the thing break on error for debugging

And Firebug also can't handle obfuscated code very well

Tim Stone

@YiJiang Yeah, you might need to like..

Disable everything in Firebug

And re-enable it.

radp

@rchern anything is related with anything else to a certain extent, so "completely unrelated" was an exaggeration :D

Tim Stone

2:39 PM

Firebug decided to stop showing exceptions for me after I was working with Greasemonkey..

But eventually I got it to behave again, heh.

rchern

@radp, ok, i don't see how they're anything but duplicates

(;

Yi Jiang

@TimStone "Disable all panel", "Enable Console", Nope, doesn't seem to work. Wonder what's GM got to do with this.

I can't imagine it doing error suppression... ?

radp

@rchern the first issue is about how GitHub's HTML page for a .user.js page is considered a userscript itself

my issue is on how you just can't see a userscript's source

Tim Stone

@YiJiang No, I don't think so, I just find Firebug to be super buggy.

radp

the first is about what a userscript is, the second is on how a userscript is handled

Tim Stone

2:41 PM

At least to the extent which I use it and have it open in multiple windows and what not.

rchern

@radp, you can't see it because chrome is interpreting anything ending in .user.js as a userscript, even when it shouldn't. which is what the 1st issue is excatly.

radp

@rchern which is the first bug

Yi Jiang

@TimStone I find it to be one of the leakest add-ons I use regularly, but not really very buggy

rchern

@radp, exactly.

radp

but in this case (2nd issue) I want to view the source of what really is a userscript!

rchern

2:42 PM

but you can't because of the 1st issue

which is why yours is a dupe (:

meh, whatever.

radp

still different.

rchern

we're going to have to agree to disagree.

radp

Yeah, I also disagree with many closings as exact duplicate around here :)

Tim Stone

@rchern I was the one who (incorrectly) pasted that code, turns out that my eyesight failed me and I overlooked where c is actually used as a function, which..you know, matches the error. Ignore me. ;)

@YiJiang It's buggy for me in the sense that things stop working for no particular reason. They'll always start working again, but they shouldn't stop working in the first place since nothing changed.

Yi Jiang

Does the chat system auto-kicks people for inactivity?

Tim Stone

2:44 PM

I do still love its awesomeness, though. ;)

But I demand a way to beautify JavaScript...I wonder if there's any easy way to hook in and make that possible.

rchern

jsbeautifier (:

Tim Stone

One thing at a time though... @rchern, I have an idea about your binding problem, but I'm not sure if I can get it to work. I'm a little disappointed in jQuery, actually.

That helps for reading, but unfortunately not for my ability to set breakpoints. :(

rchern

yeah i know hehe

binding problem?

Tim Stone

in Chat feedback on Stack Overflow Chat, 58 mins ago, by rchern

is there any way to hook into enter handling for processing my commands or am i stuck shift+enter since i can't change the order of events and i can't bind earlier than you

rchern

ah right

hmm, the code makes it look like there's a debug-messages div, but i don't see it on the page

Yi Jiang

2:50 PM

@TimStone I'm very sure jQuery maintains some sort of internal queue for the event handling functions, but I'm not sure where to look it up for that sort of things

rchern

or rather, my console doesn't see it

Tim Stone

@YiJiang It does, they just don't make it easy to get at :)

rchern

yup. there's bind and unbind.

hehe

Yi Jiang

@rchern Not good enough, unless you want to kill chat? ;)

Tim Stone

Rather, they don't make it easy to get at without me having to rewrite the entirety of one of the functions, but I think I found away around that.

rchern

2:52 PM

well, if i remember from last night, there's 3 handlers attached. [0] can stay where it is, but i'd need mine to become [1] and push existing [1] and [2] to [2] and [3]

Yi Jiang

I had no idea Firebug formats the code for you ;)

radp

nice :)

Yi Jiang

Still doesn't tell you what the variables means, but you can roughly guess what the event handler does now

radp

hrm, doesn't each jQuery object have a .text() method?

Tim Stone

If only the DOM tab wasn't super obnoxious. :P

rchern

2:58 PM

$("#input").data("events").keydown[1].handler

@YiJiang, grab FireQuery

Yi Jiang

Although slightly unfortunate that they stuffed the whole thing into a tooltip O_o

@rchern I already have fireQuery

rchern

ok, then don't (;

Tim Stone

I...don't.

rchern

ok, @TimStone, do it!

q:

Yi Jiang

Tim Stone

3:01 PM

It has been done!

Actually, super surprised that Firefox managed to restart correctly, that almost never happens..

rchern

i just ran master-chat.js through jsbeautifier and have that open in my ide

Yi Jiang

Okay, I see that c is passed into the handler, and that somewhere in the middle the line c && c() is called

rchern

that's what i've been using since yesterday

Tim Stone

@rchern What IDE do you use? Eclipse for JavaScript makes me sad.

rchern

i'm a .net person. vs (;

Yi Jiang

3:02 PM

It's probably some sort of lazy test for whether c is a function and exists

Tim Stone

Oh, right.

rchern

kinda my ide by default

Tim Stone

I haven't had to do any of our .NET/SSIS development in long enough that I don't have VS installed on this PC, heh.

rchern

@YiJiang, broken before there maybe? it doesn't scroll. weird that you're not seeing the error

Yi Jiang

@rchern I'm not sure, but it appears that the event handler expects three parameters, and I'm not passing them in correctly, triggering the error

But shouldn't c() in c && c() not run if c returns false?

radp

3:06 PM

hrm, wtf. $(".post-vote-count").first().text() works, but $(".post-vote-count").each( function(bar, obj){ obj.text() }) doesn't.

Yi Jiang

x = function(){
  console.log("Hello world");
};

x && x();

Why would somebody do this?

@radp Eh... isn't obj the DOM object, not the jQuery object?

Tim Stone

@radp You need to $(obj) don't you?

rchern

yes

radp

why would iterating over a jQuery object not give me jQuery objects?!

Yi Jiang

@radp Eh... ask Resig ;)

rchern

3:09 PM

because the jQuery array returned doesn't contain jQuery objects, it contains html elements?

radp

anyway, I asked on SO.

0

Q: Why does iterating over jQuery objects with .each() not give me jQuery objects?

The following works as expected: $(".foo").first().text("hi!") ...because first() returns a jQuery object. However, if I want to work with the text() method for all matches, I need to do: $(".foo").each( function(idx, obj) { $(obj).text("hi!") } ) ...because each() gives you DOM object...

jquery

Yi Jiang

Okay, the SO chat injects some really funky global variables and objects into window

radp

@rchern that's weird also, if I'm using jQuery to parse the document I probably want to use jQuery to change it too...

Yi Jiang

radp

insert coin

Yi Jiang

3:18 PM

Oh wait.. I just realized

radp

okay, the Eggs object doesn't behave the way I thought it did either

Yi Jiang

I can do this to find the Easter Egg!

egg must be referring to the easter egg

radp

sure, the SO easter egg is triggered by writing to the console a command

Yi Jiang

function (a) {
    if ((a = /(?:^|[.!?:]\s+)(?:(?:how\s+(?:can|do)\s+i)\s+([^?!.:]+)\?|(?:i(?:\s+want|(?:\s+am|'m)\s+(?:wanting|trying)|'d\s+like|\s+would\s+like)\s+to\s+([^?!.:]+)(?:$|\.|!)))/i.exec(a))) {
        var e = a[1] || a[2];
        if (e && e.length > 10) {
            var b = $("<div class='assistant'/>").css({position: "fixed", left: 850, bottom: 50, zIndex: 1000});
            a = $("<div/>").css({position: "absolute", right: 99, bottom: 50, backgroundColor: "#f7f0ad", border: "1px solid black", width: 300, minHeight: 100, padding: 5, fontFamily: "'Comic Sans MS', serif", fo…

There's a regex in there that's matching for something

radp

@YiJiang you don't need to work too hard on it

Yi Jiang

3:19 PM

Which then produces an AP'd, Comic Sans div

radp

@YiJiang just go on SU and write "How do I find out what the SU easter egg is?"

Yi Jiang

Hello world!

Tim Stone

Hello, @YiJiang!

Yi Jiang

Okay, let me see...

<[^>

rchern

huzzah!

@balpha showed me how to use enter instead of shift+enter

Yi Jiang

3:28 PM

@rchern Where?

Tim Stone

in Chat feedback on Stack Overflow Chat, 9 mins ago, by balpha

var e = $("#input").data("events")["keydown"]; e.unshift(e.pop());

Yi Jiang

Okay, let's see which of these Eggs function will be called

rchern

are you giving up on load? should i just take it out?

Yi Jiang

@rchern Not sure yet, wait, I've not done testing on what the three parameters mean

Tim Stone

@YiJiang Eggs.Cthulu("<[^>")!

Heh

Yi Jiang

3:34 PM

@TimStone Saw that, but is that egg active here?

Tim Stone

No, it's SO's egg.

in Sandbox on Stack Overflow Chat, yesterday, by Tim

How do I parse HTML with regex?

Heh

Yi Jiang

The thing is, after looking at the code, .click() should work

function y(c, o, q) {
    if ("which" in c) {
        c = null;
    }
    o = o || MAX_MESSAGES_DELTA;
    Na += o;
    var v = $("#chat div.message").eq(0);
    $("#getmore");
    if (v.length == 0) {
        $("#getmore").fadeOut().slideUp();
    } else {
        var z = v.attr("id").replace("message-", ""), G = $(window).scrollTop() - v.offset().top;
        z = "/chats/" + b.id + "/events?before=" + z + "&mode=Messages";
        $(q || "#getmore").html("loading&hellip;");
        if (o) {
            z += "&msgCount=" + o;

The first part there, the "which" in c part, will nullify c it was an event

Tim Stone

Do you know what calls this whole function?

Yi Jiang

@TimStone The y function? That's the event handler that's attached to the get older message button

Tim Stone

Ah

Chacha102

3:48 PM

Are Javascript exceptions useful?

Yi Jiang

@Chacha102 You mean stuff like throw new Error("My pants are on fire!");?

Chacha102

yes

Yi Jiang

@Chacha102 I think it stops the execution of the Javascript in the same block/function, erm.. can't remember

Certainly not very commonly used

rchern

i wrapped your click and settimeout in a try/catch

Chacha102

@rchern is that a sign of approval or disapproval?

Yi Jiang

3:54 PM

@rchern Okay, that confuses me a bit more

rchern

@Chacha102, hrm?

Aiden Bell

you guys, what ya like :D

Chacha102

@rchern Do you think JS Exceptions are useful

Aiden Bell

I come back and some project has kicked off

Is this the userscripts?

rchern

@AidenBell, yeah, keyboard shortcuts for chat

should tell you how much i hate using my mouse teehee

Aiden Bell

3:55 PM

@rchern - Sounds good

radp

uh, another thing

what's the difference between $(".foo").eq(2) and $(".foo")[2]?

Yi Jiang

$('div.signature:contains("rchern"').livequery(function(){
    if($(this).siblings('.messages:contains("oy!")')){
         $(this).siblings('.messages').find('.stars .vote').click();
     }
});

radp

oh, right, the first gives jQuery and the latter gives DOM

rchern

@radp, .eq will return an empty set if the index isn't found

Yi Jiang

Of course this need the livequery plugin to be included, or you can just set it to a 1000 millisecond setInterval

rchern

4:00 PM

@radp, and you can use -numbers to go from the end of the list

radp

this double nature of entity representations is confusing.

rchern

@YiJiang ...seriously?

radp

@rchern no, there's a syntax error

rchern

thinks @YiJiang has different modification reasonings than she does

Yi Jiang

@rchern I'll just.. quietly slip that into the source....

rchern

4:03 PM

...

radp

@YiJiang instead of slipping actually useful stuff like smilie backwarders?

rchern

fyi, i do want this to be a serious user script people can use >_>

hehe

Yi Jiang

@radp That would need some serious regexing, mind helping? </joke>

radp

nah, just an extensive dictionary.

Aiden Bell

@rchern what no auto-oy

?

radp

4:04 PM

js does have dictionaries right? :P

Yi Jiang

@radp objects. Objects does everything here

A bit like PHP's multifunctional arrays

radp

so if I needed a dictionary...

Aiden Bell

just use an obj and set the attrs

radp

rchern["(:"] = ":)" ?

Yi Jiang

@radp smilies = { '):' : ':(' };

radp

4:06 PM

@YiJiang oh, okay, the same syntax Python has :)

Aiden Bell

@TimStone - ah whatever, goes back to programming Python

Tim Stone

@AidenBell No, my brain failed

That was because they used an array object, nevermind.

Aiden Bell

was gonna say :P

Tim Stone

Yeah, I'm not sure where my head is today.

Aiden Bell

@TimStone never mind. I crashed and burned this morning and slept

for quite a while

The SO rooms are all pretty much dead

Yi Jiang

4:09 PM

/highlight Aiden

Oops

Tim Stone

@AidenBell Heh, I slept at some point, but maybe not enough..

Yeah, it's kind of...eerie, heh.

Aiden Bell

is there an augmentor for Chrome?

Also, has anyone actually tried delivering a webapp to the browser as XML+XSLT?

Yi Jiang

4:24 PM

Okay, /load will now work

in Chat feedback on Stack Overflow Chat, 7 mins ago, by balpha

Yi Jiang

Thanks! Everything's working as expect, whew that took so long

rchern

@YiJiang that doesn't seem very opitimized at all

Yi Jiang

At least the error isn't thrown anymore

Tim Stone

Untested, but a generic "bind this as the nth handler" bit.

Yi Jiang

@rchern Eh... who are you replying to? ;)

ChrisF

I know there's a badge at stake, but I do get annoyed when people drop the trackable link to questions into meta posts

rchern

4:36 PM

and scrollTop isn't what actually clicking the button does, does it?

Yi Jiang

@rchern True, but I think the scrolling thing is by-design, since it was designed to only be used at the top of the page

rchern

then it should scroll first and then click?

Q: Are there any negative effects when disabling Last Access timestamp

In Windows you can disable the last accessed timestamp by setting NtfsDisableLastAccessUpdate to 1 http://www.windowsnetworking.com/kbase/WindowsTips/WindowsNT/RegistryTips/Miscellaneous/RegistryTipWindowsNTNTFSLastAccessTimeStamp.html I want to do so there is less disk activity on c:\$logfil...

windows ntfs

rchern

@ChrisF, i didn't think it mattered if the click comes from within the family anyway?

Yi Jiang

@rchern No, as in, after the click is triggered, we watch for the text to return to load older messages or something, and when that occurs, we force-scroll to the bottom

But that isn't good for a number of reasons

ChrisF

4:38 PM

I thought it was tracking IP addresses - regardless of where the link actually is

Tim Stone

Right, any referrals from within the SE network don't count towards those goals.

Yi Jiang

Performance lest of them

ChrisF

Re that question - I didn't know you could turn last access off

Yi Jiang

@ChrisF Neither did I. Hmm...

Tim Stone

@ChrisF I..don't think that I knew that either, hmm.

Yi Jiang

4:39 PM

Also, why would turning that off reduce disk activity to the logs?

ChrisF

Because you're not writing the last accessed update to log

Tim Stone

@YiJiang To the NTFS log

ChrisF

The page linked to has a little bit more information

Shog9

@ChrisF Pretty sure it's disabled by default in Vista on...

(...the implication being, this is why Vista sucks)

ChrisF

@Shog9 there was a comment on my answer saying it's disabled in 7

Might be disabled because of the "new improved" Windows search

rchern

@YiJiang I guess what I'm asking is why does it need to be any more complicated than this

case "load":
                    var getMore = $('#getmore');
                    $(document).scrollTop(getMore.position().top);
                    getMore.data("events").click[0].handler(function () { });
                    handled = true;
                    break;

nice indenting hehe

Yi Jiang

@rchern Oh, I see what you mean

rchern

that's what i came up with at least shrugs

Yi Jiang

But you see, I thought that what we want is to be able to call the command from anywhere in the page

ChrisF

Interesting reading @Shog9 thanks

Yi Jiang

4:49 PM

One of my biggest annoyance of the current system is that I need to scroll up all the way to the top for stuff to load

Well of course that'd work too. Better, in fact

rchern

@YiJiang, in what situation do you want to /load but not have the window move to those messages?

Yi Jiang

@rchern Well, since that button is always at the top, why not just scrollTop(0)?

@rchern When I'm slowly reading upwards, since the loading takes a bit of time I'd find it annoying to have to wait, I'd like that thing to auto-load before I get there

ChrisF

Gah all the sites are being really slow for me today

rchern

.scrollTop(0) works too

Yi Jiang

@rchern They're using the scrollTo plugin, we can use that too to animate the scrolling

$(document).scrollTo(0, 400);

rchern

4:55 PM

i'm not sure that will scroll you to where you want given the ajax changing the page.

Yi Jiang

@rchern Hmmm... why not give it a try? ;)

rchern

i thought you were the one writing load (;

q:

brb anyway

Yi Jiang

Ironically, this works

$('#getmore').data("events")["click"][0].handler(function(){$(document).scrollTo(0, 400);});

Hehe... that useless empty function isn't so useless after all

Coincidentally, we might also want a /scroll command ;)

Tim Stone

dl.dropbox.com/u/13381087/jquery.fn.bindas.js

Just in case you need that handler insert ability in more than one place.

Yi Jiang

5:22 PM

dl.dropbox.com/u/1722364/se_chat_modifications.user.js

Includes /highlight and /load

Syntax: highlight [message_id | author name] - You only need to have part of the author's name for this to work. This will highlight all and incoming messages by that author

Highlighting a specific message can also temporarily bookmark an important message so that it can't get lost in the stream of messages

Tim Stone

That....is awesome.

Yi Jiang

/load will simply load the next few messages before scrolling all the way to the top

Also, don't try to use /highlight with numbers if you need a specific user, like when you're trying to select a user12345 with 12345 - the script differentiates the two by looking at whether the argument is a valid integer, so will attempt to highlight post id 12345 instead

Oh, and all highlighting will be lost on reload of course, so use bookmarks if you really need to keep a message

'Night from GMT +8!

Tim Stone

@YiJiang You mean that you aren't going to hijack my browser and persist this information?! Bah, what's the use then? ;)

Good job, and g'night!

/highlight @YiJiang

Hmm

Oh, without the @

Heh

rchern

back

Yi Jiang

Oh and I forgot!

/clear for clearing highlights

It'll clear all highlighting

rchern

5:31 PM

hmm, think we can improve on that

i'll take a look

i think this needs to be re-factored into a better command pattern

Tim Stone

The massive switch statement has class, though.

rchern

lol

Tim Stone

But yes, a commands object for commands[command]() ing might not be a bad idea.

Oh, they've turned your rep into a link to privileges..

/load

...Err, am I doing something wrong?

rchern

@YiJiang's version doesn't have the enter code and still requires shift+enter probably

Tim Stone

Ah. :)

Hm, no, shift+enter gives me a newline..

Though it also appears to be true that it still requires shift+enter.

Ah, Firefox fail.

rchern

5:48 PM

?

Tim Stone

I had reloaded the page, but apparently Firefox didn't agree that I had really reloaded the page, so it didn't bother to inject the new Greasemonkey script. F5 seems to have fixed that..

Not sure how that makes any sense, but I definitely pressed the reload button.

rchern

haha

Tim Stone

/load

Oh right, shift+enter

I really need to fix whatever is lagging my brain today.

There we go.
