What is meta? ×
Meta Stack Exchange is where users like you discuss bugs, features, and support issues that affect the software powering all 128 Stack Exchange communities.

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 100 reputation to edit)
  • post answers to this question (Since this question is protected this requires 10 reputation)
  • post comments to this question or its answers

Beware that since the changes to syntax highlighting in December 2010, and the inline hints added 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. Set some language tags to this question:

    • See the explanation and the list of languages.

    • Adding clashing tags, such as both and , enforces a fallback to default, which is different from "no highlighting". (These tags are currently set on this question.)

  2. Or: on the start of a line, specify a language inline using <!-- language: lang --> hints, and indent the code 4 spaces as usual. There is a full list of hints (scroll down a little).

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

    • Save your post.

    • Use something like Firebug (Firefox), Web Inspector (Safari, Chrome) or Developer Tools (Internet Explorer 8) to edit the resulting HTML. To open Chrome Dev Tools, press F12

    • Find the <pre> element and add the attribute class="prettyprint", or change it into something more specific, like class="lang-vb prettyprint".

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

Header 2

Bold Italics

public void StackOverflow() { StackOverflow(); }

The StackOverflow() function calls itself, causing a StackOverflowException or StackOverflowError (.NET and Java respectively).

Breaking the workflow:

There are probably children out there holding down spacebar to stay warm in the winter! YOUR UPDATE MURDERS CHILDREN.

Duplicating Python3's print() function is easy. Make a function that takes an argument, named whatever you want, then print that argument when the function is invoked from the interpreter. Easy.

def println(stringint):
    print stringint

Here's how you'd invoke it in your interpreter with the argument.

>>> import <filename>
>>> <filename>.println("Hello, this is a test.")
Hello, this is a test.
>>> <filename>.println(12 / 2 + 6)
12

You can also invoke it like this, without having to add the filename.

>>> from <filename> import println
>>> println("Hello, this is a test.")
Hello, this is a test.
>>> println(12 / 2 + 6)
12

There you have it, a duplicate of Python3's print() function. Yay.
