Notes:

  • Answers will occasionally be moved to the Sandbox archive when there are too many of them. When using them to report bugs, keep an eye on the post.
  • Stack Exchange sites are moving to a new syntax highlighter. This site, Meta Stack Exchange, as well as Meta Stack Overflow, are on the new highlighter, while all other sites are still using the older one. If using this post to test out syntax highlighting, the highlighting that appears here may or may not match that on the other sites until those are upgraded as well.

As per Jeff's suggestion in this comment:

You can use this question as a formatting sandbox. You can:

  • edit this question itself (Community Wiki questions such as this one require only 100 reputation to edit instead of 2,000)
  • post answers to this question (This question might be protected, requiring earning 10 reputation on this site to answer)
  • post comments to this question or its answers
  • test suspected bugs with the editor or the rendering
  • post ponies (only when mods are asleep)

Beware that since the changes to syntax highlighting in December 2010, and the inline hints added in March 2011, no syntax highlighting is applied unless the question's tags or an inline hint enable it. So, to test highlighting here in the sandbox:

  1. As of January 8, 2019, you can use GitHub-flavor fenced code blocks in your posts, specifying the language after the opening fence:

    ```html
    While not hinted otherwise: <html></html> source <b>goes</b> "here".
    ```
    
    ```js
    var a = 3;
    while (not (a > 0)) {
        alert("JavaScript code <b>goes</b> here.");
    }
    ```
    
  2. Or:

    • Create code blocks in any way (using the fence notation above, the four-space indent form, or using HTML <pre><code> tags).

    • Save your post.

    • Use your browser's developer tools to edit the resulting HTML. To open developer tools, press F12, or ⌥⌘ I on Mac.

    • Find the <pre> element and add the attribute class="prettyprint", or change it into one of the valid syntax hints linked above, like class="lang-vb prettyprint".

    • Run the following in the location bar: javascript:prettyPrint(); or prettyPrint() in the console.

Answers that are considered annoying or obnoxious, or that cause breakage for users, will be deleted. This is codified as a policy as of March 29, 2018.

  • @BhargavRao When sandbox answers are moved to the archive, comments such as this one -- on the question itself -- aren't migrated; they're deleted. – rgettman Apr 9 '19 at 19:37
  • @rgettman, yeah, that is fine. I had used it for just a small demonstration. The linked answer itself is self-sufficient. Thanks anyway. – Bhargav Rao Apr 9 '19 at 20:22
  • @BringBackThePolyglot Do you get notifications if I reply to your comment and then delete your comment before you visit the site? (for those wondering how I can single-handedly delete someone else's comment, comments containing "thanks" are automatically deleted as soon as someone flags them) – Donald Duck Apr 25 '19 at 16:32
  • @DonaldDuck Yes, I got notified. – Bring Back The Polyglot Apr 25 '19 at 16:32

I’m testing hyphens ("HYPHEN MINUS") on iOS 12. Specifically, typing multiple hyphens into the edit box. Typing 2 hyphens together results in a single "EM DASH".

Related question on the Ask Different Stack:
How do I type a hyphen in iOS 12?

The text in parentheses describes the resulting string after typing N hyphens.

Below this line is a single “hyphen” (HYPHEN)

-

Below this are 2 hyphens (EM DASH)

And 3 hyphens (EM DASH + HYPHEN)

—-

Four hyphens (EM DASH + EM DASH)

——

-—

Five hyphens (EM DASH + EM DASH + HYPHEN)

——-

Long press and second character (EN DASH)

Long press and third character (EM DASH)

Copy/paste




Hello -

• (BULLET - Long press and first character)

Saying "hyphen hyphen hyphen hyphen" results in 4 contiguous hyphens


Saying "dash" results in an "EN DASH" and "dash dash dash dash" results in 4 x "EN DASH + SPACE" (not contiguous).

Does LaTeX formatting work? Let me test.

Testing whether a formatting bug was removed by CommonMark (Success?)

Before CommonMark:

enter image description here

Notably there is no white space or gap between "commodo consequat" and "Duis aute".

After CommonMark (if spaces and > are added):

  • Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.

    • Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat.

Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. [Yuck! This is the problem!]
