Code Golf UserScript to help in navigating the site [v0.37 now available]

Question

Current version:

The current version of the script is 0.37.

---

I was inspired by this Meta post to write a UserScript that would automatically tally up the size of code blocks and display the count underneath.

A couple weeks later and I now have a giant UserScript that is over 32kb in size :)

Well, how can I install it?

I'm glad you asked! Since this is a UserScript, a few browsers allow you to install it by simply clicking on the link below and downloading it.

I have tested the script on Chrome (needs this workaround), Firefox (with GreaseMonkey), and Opera. It is reported to work on Safari using GreaseKit.

What does it do exactly?

This list seems to grow every day, but here is a (somewhat) exhaustive list:

• Analysis and display of exact character count of each code entry (with syntax highlighting):

  

  Note: you can even directly run some entries by clicking the '[Run]' link

• Summary of entries for a particular question, including the current winner(s) for shortest code:

  

• The ability to sort the answers on the page by the size of their code:

  

• An evolving options menu for changing the settings for the script:

  

• An experimental theme that can be injected onto the pages of the site:

  

What about updates?

Yes, this humble UserScript is now capable of updating itself. Every 24 hours, it checks to see if there is a new version available. If so, it will prompt you to download it. You will have the option of choosing not to install the update if you don't want to.

Answer 1

Please support binary hex dumps counter. an example here, and copy-pasted as follows.

0000000: 332c 7b3a 533b 2e7b 3438 2d22 5e70 285d  3,{:S;.{48-"^p(]
0000010: 7025 d3c4 4ab1 7d4a b8dc 4469 ce41 2222  p%..J.}J..Di.A""
0000020: f303 227b 6261 7365 7d2f 3330 2f53 3d33  .."{base}/30/S=3
0000030: 2f3d 7b22 5f20 7c22 3d7d 257d 256e 407d  /={"_ |"=}%}%n@}
0000040: 2f3b                                     /;

My current idea is that, if the .text() is startswith /^0{3,}: / which is 0000000: then do
.text().match(/ [\da-z]{2}|[\da-z]{2}(?= )/gim).length, which gave me 66 chars.

There is another one here with slightly different format. Should work too, but I havn't tested well that though :)

Answer 2

It looks like the userscript and the new 'Grainy' theme have a small issue. All inline code blocks are displaying as block making some comments with suggestions for corrections etc. really long. Example 1, example 2. It's not serious - nothing's actually broken - but I thought I'd let you know.

As a temporary workaround until this is officially fixed, you can edit the script source (via Manage User Scripts... from the Greasemonkey menu) and add the following line somewhere after the header:

GM_addStyle("code.prettyprint { display: inline; }");

Answer 3

Dealing with line breaks correctly is non-trivial.

Just looking at c-like languages there are at least three classes

1. The newline ending a pre-processor line. These are required and should count.
2. Newlines inserted only for limiting line length. They shouldn't count unless...
3. Newlines for limiting line length inserted in lieu of a space that would otherwise be required which should count.

And telling the last two classes apart requires lexing the preceding and subsequent "words" with and without some whitespace to know if they can be safely jammed together. And that, of course, is language specific.

Answer 4

When you extract username, could you strip revision part?

for example, Forecast the weather

Current winner: 21 revsJoey's [Unknown] entry has 103 characters.

probably, .replace(/[^<]+<br>/,'') will work.

Answer 5

I have added a menu to the top of every page now:

However, the options item is not functional. I was wondering if anyone had any ideas as far as configurable settings goes:

• What settings do you want to be able to configure? For example, perhaps it would be nice to be able to add extra languages to the search list or to disable certain features?

• How should these settings be stored? Should I continue using cookies, or turn to HTML5 local storage? Any thoughts?

Answer 6

Questions to consider:

Here are some things to be considered and discussed as this little script grows in functionality.

• What languages do we want to skip? Someone on the chat mentioned that there are some languages (like HQ9+) that should be skipped and not counted when determining the smallest piece of code.

  Update: HQ9+ is now disqualified.

• Does the character totaling code need adjustment? There are a few things to consider when totaling up the characters in a code snippet. Like: Should all newlines count?, Should trailing and leading newlines count?, Indentation?

Please comment below to voice your opinion on these issues.

Answer 7

Suggestion: Include scores for the posts.

Anarchy Golf gives 10000 points to the shortest answer(s) and after that the score is calculated as follows:

minimal solution length
----------------------- ⋅ 10000
   solution length

So a solution twice the length of the shortest one will have 5000 points.

That way you have a rough measure how close each solution is to the currently top-rated one.

Answer 8

Perhaps if the code provided is valid base64, your script should detect that and display the size it would have when decoded, which is easy to calculate: remove all the whitespace, remove the trailing = characters, multiply the length by 3 and divide by 4 (round down).

To give an example where it makes sense to post a base64-encoded answer, see my Perl script that uses unprintable bytes in the source.

You may use, .find('.user-details a:last').text(), since author is on the right most
