John Resig annotates original jQuery source code
- cryptoz 11y agoVery neat content, but does it have to be formatted like this? I respect that it preserves the original file, but it makes it very difficult to read. Comments added to the source code would serve much better for the purposes of understanding the code. This tool makes it impossible to read the annotation and the source code at the same time. Clicking on 'set' for example, about 20-30 lines in, lets you read the annotation, but not the function. You have to hide the annotation to read the code. Wouldn't inline/multiline comments be so much better than this? Edit: Citation/example: http://i.imgur.com/CHOFGML.png http://i.imgur.com/CHOFGML.png

- jasonlotito 11y agoCame here to say this. I cannot fathom how this is considered usable at all. There are also times that you click on the block of code to read, and it sends you back to the top of the page. I'm more interested now in how this application got pushed to production in its current state.
- hiby007 11y agoI am facing the same problem. I am going back to top of the page when I click on the long block of code.
- sic1 11y agoI just want the comments in a fixed window that is draggable so i can put it where i want. I think that would make everyone happy...or at least be better. Great content tho, enjoying the read.
- glossybrown 11y agoSorry about this bug! We're working on a fix now. Definitely one of the biggest challenges in building this product is getting the annotation interface to work consistently in a “host page” environment over which we have pretty much no control or advanced knowledge. So for instance, the jump-you-to-the-top bug isn't something we've seen in the general case; we're currently getting to the bottom of why it's happening on this particular page.
- pests 11y agoI noticed it happened on the last annotation that was at the edge of the screen. It looks like you position the annotation box at this height. That might have something to do with it. Also, after a long piece of annotated text its annoying that the box pops up at the very bottom of the text rather than side by side.
- nostromo 11y agoI like it. It almost makes me wish I could comment my code like this somehow. I often find that long comments can break my flow when reading code -- but of course, commenting is necessary, so perhaps it could be useful to pull them aside in an IDE. Does something like that exist?
- markm208 11y agoThere is something that I have been working on: https://vimeo.com/97711978#t=0m37s https://vimeo.com/97711978#t=0m37s
- ThrustVectoring 11y agoThere's likely some way to have Vim automatically fold and hide comments. Then, they're one line when not needed, and a `zo` away when you want to read them.
- OvidNaso 11y agoIsn't this sort of the original intent and purpose of Literate programming. I just spent a bunch of my time creating my emacs configuartion in org-mode using babel [0] and man, it was a cool experience. You can comment out the wazoo, linking to the web, other files or other parts of the same file all organized in a custom hierarchy or whatever you choose. Then just C-c C-v t and all the source code is in a clean seperate file. You can even set it up to include the comments, link to the comments, or whatever other way you want the output to be. If I ever pursue programming more seriously, I can't image not seriously trying to do it in this manner. 0. http://orgmode.org/worg/org-contrib/babel/ http://orgmode.org/worg/org-contrib/babel/
- jostylr 11y agoI wrote a markdown based version of literate-programming that allows one to write it with lots of comments and organize the code in anyway you wish. But then when compiled, you can see all the code without all the long comments. You can still have normal programming comments in there, of course, but the detailed thinking (the why and an overview of relations to other parts) can be taken away. https://github.com/jostylr/literate-programming-lib https://github.com/jostylr/literate-programming-lib
- toxican 11y agoI like the cleanliness of how it is now and I like the preservation of the original file, BUT the annotations seem to pop up wherever they want to without rhyme or reason. Why not just have them pop up on the right side of my screen? Or have a dedicated annotation block that scrolls with me, but well away from the content itself?
- metamet 11y agoWhy they did it this way and not like their other branches makes no sense. See: http://genius.com/Kendrick-lamar-king-kunta-lyrics http://genius.com/Kendrick-lamar-king-kunta-lyrics
- maxmcd 11y agoThis formatting style for annotated sources always seems to work so well: http://robflaherty.github.io/jquery-annotated-source/docs/01-core.html http://robflaherty.github.io/jquery-annotated-source/docs/01...
- gearhart 11y agoAbsolutely agreed - I just had to click 40 times to read 40 comments when I had half a screen's worth of whitespace they could've just been sitting in...
- Mahn 11y agoSeconded, if you are going to annotate source code please go for this format.
- lelandbatey 11y agoIndeed, that side-by-side annotated style is great. For those who would like to create similar pages, the original program is Docco[0], a Javascript project. However it's been ported over to many other languages and can be found in these projects: - Pycco[1] Python - Rocco[2] Ruby - Shocco[3] POSIX Shell - Many more, as found here[4] Note each of these projects support highlighting different languages. For example, the Pycco[1] project uses the Pygments library for language handling, and thus supports many different languages. Others, like Shocco[3] only support one language (Shell in the case of Shocco).

- nosefrog 11y agoI agree, Docco-style docs are really easy to read. I built srcco, a Docco-style doc generator that links every variable, function, etc. within your project to its definition (similar to sourcegraph.com -- full disclosure: I work at Sourcegraph), to demonstrate how to build things on top of our free/open source language analysis framework, srclib[0]. You might find it interesting (the links in the code have white backgrounds): http://sourcegraph.github.io/srcco/srcco.go.html http://sourcegraph.github.io/srcco/srcco.go.html It only works for Go because the only Go toolchain keeps track of comment ranges (because srcco removes the comments from the source code), but it wouldn't be too hard to add comment ranges to the other toolchains. If you are interested in language analysis for languages like Java, Python, Haskell, or Javascript, I would be happy to help you make your first contribution. Ping me: samer@sourcegraph.com.

- TeMPOraL 11y agoIMO this is cool, but it would be even better if it was in the right margin, so it wouldn't overlap with and hide the code.
- Eyas 11y agoThe main difference between Genius-style annotation and code comments, which I think is important to note (and valuable) is that code comments annotate a point or position in the source, while genius annotations are referring to a span or range in the source.
- darklajid 11y agoWell, I think the idea is sound. I'm even into Hip-Hop/Rap, so I should like them. Unfortunately the user interface is a world of pain. It's unusable. It's worse than quora. Good idea, but the execution needs work.
- Eyas 11y agoAgreed. Just separating concept from implementation.
- dragonwriter 11y ago> The main difference between Genius-style annotation and code comments, which I think is important to note (and valuable) is that code comments annotate a point or position in the source, while genius annotations are referring to a span or range in the source. I don't think that's necessarily true; code comments very often refer to a range in the source. Because code is generally designed to be accessed as linear text without hyperlinking facilities, the identification of the range is usually something that the reader has to interpret by applying (sometimes language specific) conventions relating to code formatting, indentation, and the precise placement of comments, and there are a limited set of kinds of spans that conventions cover (e.g., a span that starts in one block but extends to include the following part of the containing block doesn't have a good layout convention to indicate that a comment goes with it.) Genius-style annotations, because they aren't limited to conventions that work in a strict linear text medium, can easily refer to arbitrary spans of content.
- StavrosK 11y agoThis looks like an ad for Genius, though, so that'd be why.
- hamburglar 11y agoIf it's supposed to be an ad for Genius, it's a pretty lousy one, in my opinion. Half of the time I click on a highlighted line, it opens the annotation and then scrolls away, so I can't see it. It's pretty frustrating. And the "view on Genius" link redirects to the top-level Genius.com page, which just makes me sigh and close the window.
- krick 11y agoDoesn't matter. People will be like "Oh! John Resig uses Genius! Looks like that's actually real software for the cools guys, not some stuff nobody uses." Usability is optional for that.
- itsbits 11y agonaah..its only for sometime. Agreed that people surely gonna have a look on it since JOHN RESIG uses it but usability only helps you to keep on using it.
- AwesomeTogether 11y agogenius is based in New York I think, and so is John Resig (at least at lot of the time, he attends JS meetups in New York). He's probably doing them a favor, although the founders of genius are rather obnoxious and John's just the opposite, so it's not whom I'd expect him to help out. Maybe he's going for funding from Horowitz, who also funds genius
- stronglikedan 11y agoIt would be nice if you could simply drag the modal once it's rendered. I think that would be the most simple solution.
- oneeyedpigeon 11y agoExactly what I was thinking. I'm sure there's some kind of cross-browser, front-end javascript library that you could use to achieve this :)
- staunch 11y agoI found myself wishing this was a screencast.
- jtokoph 11y agoPaul Irish has done a few videos where he walks through some of the jQuery code: http://www.paulirish.com/2010/10-things-i-learned-from-the-jquery-source/ http://www.paulirish.com/2010/10-things-i-learned-from-the-j...
- swavaldez 11y agoI can't believe that article was five years ago already! >.>
- wehadfun 11y agoI would actually like this in an IDE. Visual Studio kind of does this with header comments but it would be great to be able to show/hide comments with links, rich text,...
- ThrustVectoring 11y agoVim's folding doesn't do this out-of-the-box, but you can set it up to do so. Clickable links aren't doable, though copying and opening in a browser tab is something like seven keystrokes on my current setup.
- beaumartinez 11y agoIn modern Vim (with netrw), you can type `gx` when the cursor is over a URL to open it in your browser.
- Saturnaut 11y agoKind of surprised Sublime Text 2 / 3 doesn't have a plugin that allows for annotation.
- sisivee 11y agoYou might want to check this out: https://srclib.org/plugins/sublimetext/ https://srclib.org/plugins/sublimetext/ srclib is the open-source library that powers Sourcegraph, a code search engine.
- Stratoscope 11y agoIt's very kind of John to mention my first jQuery plugin in the notes. Unfortunately, it was not a very good plugin and probably set a bad precedent. Like so many new jQuery developers, I went "Chaining? Whoa. Chain all the things!" So I attached the plugin to $.fn, not thinking about the fact that what the plugin did had very little to do with the current element selection. I may have been the first to make this mistake, but at least I wasn't the last. :-) Perhaps I redeemed myself by coming up with the idea to use $.prototype for plugin methods instead of copying the method references by looping through $.fn (we kept $.fn as an alias of $.prototype for compatibility). So a $(...) call became a lot faster.
- Terr_ 11y agoI suspect a lot of the "unnecessary chaining" that occurs is really a problem of people (A) making something that requires jQuery and they don't want to think about how to ensure that dependency, while (B) liking the idea of associating their little thing with a big-name project. Then you get things like $("#target").MakeBobsFancyBoxWidget()
- pearjuice 11y agoThough Resig's anecdotes are fun and interesting to read, it doesn't help that much with understanding the actual source code. Here's a better version in terms of readability and depth: https://robflaherty.github.io/jquery-annotated-source/ https://robflaherty.github.io/jquery-annotated-source/ https://robflaherty.github.io/jquery-annotated-source/docs/01-core.html https://robflaherty.github.io/jquery-annotated-source/docs/0... Sadly, no longer updated since jQuery 1.6.2 which was released in 2011.
- gregor7777 11y agoOut of curiosity, do you know of any other ubiquitous projects that have had a similar treatment?
- dmethvin 11y agoThe comments in the current jQuery source are pretty good about explaining the strange things that need to be done to work around bugs in browsers. Look for the `// Supports:` comments.
- danso 11y agoThe annotations are also a great reminder of how programming used to be not so long ago. It's hard to imagine having to search Internet Archive for your own source code in this age of Github: http://genius.com/5088475 http://genius.com/5088475 > Note: This may not be the first first code released, but it appears to be the earliest copy that we’ve found, so far. This is a copy that was indexed by the Internet Archive on Feb 3rd 2006, so about 2.5 weeks after the initial release. It’s very likely that a few things changed in that time period and I’ll try to make a note of some of those, that I can remember, inline.
- buzzkills 11y agoWow, makes me feel a little better that he had 75 open source projects before he had a 'hit'. :)
- misiti3780 11y agowhere did you see that ?
- swavaldez 11y agoIt was stated in one of his annotation
- IgorPartola 11y agoAnyone else already find the XSS in genius.it? Edit: wow, the whole thing is seriously broken. Emailing them now. Edit 2: It's not as broken as I thought, and these guys are quick to reply and try to figure things out. To be clear, I haven't gotten it to run arbitrary JS, just include arbitrary HTML, which isn't as dangerous.
- tomlemon 11y agoLet us know this'd be very helpful! tom@genius.com
- IgorPartola 11y agoEmailed.
- paulirish 11y agoBTW would really love to link to a particular annotation.
- IgorPartola 11y agoI noticed it when http://genius.com/5104616 http://genius.com/5104616 was broken where John included the <div> tag.
- glandium 11y agoHow is including arbitrary html not as dangerous, when arbitrary html also means <script> tags?
- nightpool 11y agoI'm not sure what exactly he's referring to, but annotations allow you to use markdown and some (limited, heavily sanatized and whitelisted) html, so that could be what he was talking about.

- curiously 11y agowould love to see a frontend framework that uses jQuery syntaxes only.
- pdevr 11y agoAmazing that it has been more than nine years since the original release (Jan 14, 2006)! How long did it take for John to write this initial version? Any idea?
- jeresig 11y agoI don't have exact records but based upon what I was inspired by, and what else I was working on at the time, it roughly equates to the fall of 2005. I was in college at the time and taking classes so I was working on it on-and-off as my schedule allowed. I finished it up over winter break and went with some friends to BarCamp NYC 2006 and released it there.
- pdevr 11y agoThanks John, always good to hear straight from the horse's mouth!
- Vekz 11y agoMaybe I missed the release announcement on this genius.it thing but thats the real story http://genius.it/https://news.ycombinator.com/item?id=9336297 http://genius.it/https://news.ycombinator.com/item?id=933629...
- stevebot 11y agoSo glad jQuery came along and became what it is. Scary to think of a world where it was just bundled alongside Prototype. For those not versed in Prototype, those were dark days (at least for me).
- kedean 11y agoI always kind of wished that MooTools had won out in their battle to overtake Prototype's crown. It had a much more sensible namespace, and focused much more on solidly structured code over "how short can I make this".
- Zelphyr 11y agoIf you're a new or relatively new developer I highly recommend reading through things like this. All too often developers get in the habit of writing a lot of code without also reading what other more experienced developers have written.
- ggamecrazy 11y agoIt's 500'ing for me, anyone else seeing this?
- deleted 11y ago[deleted]
- nothrabannosir 11y agoWhat surprises me is the lack of comments in the original file. This leads to e.g.: this._get(i).$$tmpFunc = f; this._get(i).$$tmpFunc(i); this._get(i).$$tmpFunc = null; with the comment (from now): So this may look crazy — it certainly does to me! Why not just do: f.call(this._get(i))? If I remember correctly, and I just did some double-checking and I think this is the case, but IE 5 didn’t support .call()! The original version of jQuery event worked back to IE 5… I can hardly believe. I personally hate coming across snippets of code like this (usually from myself ): ). What do I do here? Can I just replace this with .call? Why did he not do .call? Performance? Or just MSIE5 (if I ever figure that out in the first place). All my respect to mr. Resig, of course! What an almost legendary piece of software. Just interesting to see that this commentless programming is something of all pedigrees. And a note to people saying "learn from this," please also learn that without the original author and rapgenius, we would never have understood that part. Or at least I wouldn't.
- jeresig 11y agoAbsolutely agreed - comments are so important! Seemingly when I was working on jQuery alone and without much feedback I was totally fine just having no comments. I noticed that in the subsequent releases of the code that the number of comments quickly rose - likely as people started to use the library I felt bad that the code was so poorly explained!
- jcampbell1 11y agoI still have 0.3 in my code base, and there are some gems like: // Arrrrghhhhhhhh!! // I overwrote the event plugin's .load // this won't happen again, I hope -John BTW, do you know what happened to Dean Edwards. He was doing some really interesting work around the same time as you.

- igravious 11y agoWhat's the standard the Genius uses to perform annotations? Anybody know?
- swavaldez 11y agoAnyone knows if there are outdated sites that still using early versions of jQuery? =))
- jeresig 11y agoI don't have any links off-hand but I know that there was a Nintendo.com sub-site that was using a pre-1.0 version of jQuery. Even though the overall code quality is rather low it did have decent browser support - unless browsers actively begin breaking their APIs (unlikely) those old versions of jQuery will probably keep working forever!
- seanalltogether 11y agoif ( !b ) for ( var j in a ) this.style[j] = a[j]; else this.style[a] = b; I really dis-liked having unnecessary braces. This… unfortunate… style preference plagued us for quite a while and caused all sorts of avoidable logic errors. I really wish this kind of coding was removed completely from some languages.
- alelefant 11y agoI'm sorry, but this has to be said. This guy loves exclamation points! Almost every paragraph features one. It reminds me of a great Seinfeld episode: Jake: Well, maybe I don't use my exclamation points as haphazardly as you do. Elaine: You don't think that someone having a baby warrants an exclamation point. Jake: Hey, I just chalked down the message. I didn't know I was required to capture the mood of each caller. Elaine: I just thought you would be a little more excited about a friend of mine having a baby. Jake: Ok, I'm excited. I just don't happen to like exclamation points.
- gcb0 11y agoon mobile: i only see the code. sigh. why even serve me a different page? I'm running full blown Firefox.
- yukinon 11y agoFirefox 36, OS X. This doesn't seem to be working for me at all.
- golergka 11y agoIs there a list of other source code annotations on Genius? Their "tech" section of the web site is full of crappy startup news and doesn't even link to this gem.
