Try adding the `(?s)` inline flag start the start of the pattern. That will make `.` match _any_ character.

I am using a Jquery plugin called [datatables][1]

Its fantastic, however I cannot get the dates to sort correctly according to the dd/mm/yyyy format.

I have looked at their support formats but none of these fixes seem to work.

Can anybody here help me please?

Datatable date sorting dd/mm/yyyy issue

If I have:

	unsigned int x;
	x -= x;

it&#39;s clear that `x` *should* be zero after this expression, but everywhere I look, they say the *behavior* of this code is undefined, not merely the value of `x` (until before the subtraction).

Two questions:

- Is the *behavior* of this code indeed undefined?  
  (E.g. Might the code crash [or worse] on a compliant system?)

- If so, ***why*** does C say that the *behavior* is undefined, when it is perfectly clear that `x` should be zero here?

	i.e. What is the *advantage* given by not defining the behavior here?  

Clearly, the compiler could simply use *whatever* garbage value it deemed &quot;handy&quot; inside the variable, and it would work as intended... what&#39;s wrong with that approach?

(Why) is using an uninitialized variable undefined behavior?

Is there a way to match any character in Sublime Text, including newlines? I saw that Sublime uses Boost&#39;s syntax but that the `.` character won&#39;t match newlines without a specific flag set.

I have a string: 

    var string = &quot;aaaaaa&lt;br /&gt;&amp;dagger; bbbb&lt;br /&gt;&amp;Dagger; cccc&quot;

And I would like to split this string with the delimiter `&lt;br /&gt;` followed by a special character.

To do that, I am using this:

    string.split(/&lt;br \/&gt;&amp;#?[a-zA-Z0-9]+;/g);

I am getting what I need, except that I am losing the delimiter.
Here is the example: http://jsfiddle.net/JwrZ6/1/

How can I keep the delimiter?

Javascript and regex: split string and keep the separator

I&#39;m trying to create a regular expression to validate usernames against these criteria:

 1. Only contains *alphanumeric* characters,
    *underscore* and *dot*.
 2. Underscore and dot can&#39;t be at the *end* or
    *start* of a username (e.g `_username` / `username_` / `.username` / `username.`).
 3. Underscore and dot can&#39;t be *next to each other* (e.g `user_.name`).
 4. Underscore or dot can&#39;t be used multiple times *in a row* (e.g `user__name` / `user..name`).
 5. Number of characters must be between 8 to 20.

This is what I&#39;ve done so far; it sounds it enforces all criteria rules *but the 5th rule*. I don&#39;t know how to add the 5th rule to this:

     ^[a-zA-Z0-9]+([._]?[a-zA-Z0-9]+)*$

Regular expression to validate username

I have this function to validate an email addresses:

    function validateEMAIL($EMAIL) {
        $v = &quot;/[a-zA-Z0-9_-.+]+@[a-zA-Z0-9-]+.[a-zA-Z]+/&quot;;

        return (bool)preg_match($v, $EMAIL);
    }

Is this okay for checking if the email address is valid or not?

How can I retrieve the word `my` from between the two rounded brackets in the following sentence using a regex in JavaScript?

&gt; &quot;This is (my) simple text&quot;

I have a string. The end is different, such as `index.php?test=1&amp;list=UL` or `index.php?list=UL&amp;more=1`. The one thing I&#39;m looking for is `&amp;list=`.

How can I match it, whether it&#39;s in the middle of the string or it&#39;s at the end? So far I&#39;ve got `[&amp;|\?]list=.*?([&amp;|$])`, but the `([&amp;|$])` part doesn&#39;t actually work; I&#39;m trying to use that to match either `&amp;` or the end of the string, but the end of the string part doesn&#39;t work, so this pattern matches the second example but not the first.

In regex, match either the end of the string or a specific character

I just switched to Sublime Text as my new editor. If I open the sidebar it shows the opening file, but what I want is a file navigation sidebar, is it possible to change that without downloading plugins? 

Sublime Text 2 - Show file navigation in sidebar

Let&#39;s say I had a text file with the following nine lines:

    foo
    
    bar
    
    baz
    
    qux
    
    quux

How can I use Sublime Text 2 to remove all four of the blank/empty lines, leaving only five lines?

Sublime Text 2: How to delete blank/empty lines

Sublime sees `.m` files as Objective C files.  

I&#39;ve been given a bunch of MATLAB/Octave files to work with using Octave, all with `.m` extensions.  

If I change the extensions to `.matlab`, then Sublime will recognize them and format them correctly, but then Octave doesn&#39;t see them.

I would like to either:

(1) alter Sublime so that it recognizes `.m` as MATLAB/Octave instead of Objective C, or

(2) tell Octave to recognize `.matlab` as something it can just run.

I&#39;ve poked around on the Sublime and Octave sides of this, but to no avail ([this](https://stackoverflow.com/questions/6964348/overlap-between-objective-c-and-matlab-octave-file-extensions) is not the answer), and I&#39;m an Octave noob.  Thank you.

.m files as MATLAB/Octave for Sublime Text

In Sublime Text 2, I&#39;ve seen ways of basing the syntax off of the extension. But what about a filename with no extension? For example, I often have a file called &quot;Vagrantfile&quot; which is in ruby, yet Sublime Text 2 always wants to start off in plain text. Is there a way to have it default to &quot;ruby&quot; for a file if it is called &quot;Vagrantfile&quot;?

Changing default syntax based on filename

In notepad++ there is a toolbar button to switch on/off display of EOL characters, i.e. carriage return and line feed.

Can Sublime Text 2 do the similar thing?
