Put the white space chars you want to match inside a character class. For example:

    [ \t]{2,}

matches 2 or more spaces or tabs.

You could also do:

    [^\S\r\n]{2,}

which matches any white-space char except `\r` and `\n` at least twice (note that the capital `S` in `\S` is short for `[^\s]`).

Regex to target only two spaces:
[ ]{2,}
Brackets in regex is character class. Meaning just the chars in there. Here just space. The following curly bracket means two or more times.


If have the following plural ressource in my strings.xml:

       &lt;plurals name=&quot;item_shop&quot;&gt;
            &lt;item quantity=&quot;zero&quot;&gt;No item&lt;/item&gt;
            &lt;item quantity=&quot;one&quot;&gt;One item&lt;/item&gt;
            &lt;item quantity=&quot;other&quot;&gt;%d items&lt;/item&gt;
       &lt;/plurals&gt;	

I&#39;m showing the result to the user using:

    textView.setText(getQuantityString(R.plurals.item_shop, quantity, quantity));

It&#39;s working well with 1 and above, but if quantity is 0 then I see &quot;0 items&quot;. 
Is &quot;zero&quot; value supported only in Arabic language as the documentation seems to indicate?
Or am I missing something?

Android plurals treatment of &quot;zero&quot;

As I understand, `Bundle` and `Parcelable` belongs to the way Android performs serialization in. It is used for example in passing data between activities. But I wonder, if there are any benefits in using `Parcelable` instead of classic serialization in case of saving state of my business objects to the internal memory for example? Will it be simpler or faster than the classic way? Where should I use classic serialization and where better to use bundles?

Sometimes the text that it loads is too long and the text crosses the border of the form, that is some of the text is out of the form.

Is there a linq lambda search method that returns null, instead of throwing an exception, when searching a list?

My current solution is something like: (to avoid exception from being thrown)

    if (list.Exists(x =&gt; x.Foo == Foo))
    {
        var listItem = list.Find(x =&gt; x.Foo == Foo);
    }

It just feels wrong to repeat the expression.

Something like ...

    var listItem = list.Find(x =&gt; x.Foo == Foo);
    if (listItem != null)
    {
        //Do stuff
    }

... feels better to me. Or is it just me?

Do you have a better approach on this one? (The solution don&#39;t have to be returning null, just a better solution is good)

Intersect can be used to find matches between two collections, like so:

	// Assign two arrays.
	int[] array1 = { 1, 2, 3 };
	int[] array2 = { 2, 3, 4 };
	// Call Intersect extension method.
	var intersect = array1.Intersect(array2);
	// Write intersection to screen.
	foreach (int value in intersect)
	{
	    Console.WriteLine(value); // Output: 2, 3
	}

However what I&#39;d like to achieve is the opposite, I&#39;d like to list **items from one collection that are missing from the other**:

	// Assign two arrays.
	int[] array1 = { 1, 2, 3 };
	int[] array2 = { 2, 3, 4 };
	// Call &quot;NonIntersect&quot; extension method.
	var intersect = array1.NonIntersect(array2); // I&#39;ve made up the NonIntersect method
	// Write intersection to screen.
	foreach (int value in intersect)
	{
	    Console.WriteLine(value); // Output: 4
	}

I&#39;m trying to find every 10 digit series of numbers within a larger series of numbers using re in Python 2.6.

I&#39;m easily able to grab no overlapping matches, but I want every match in the number series.  Eg.

in &quot;123456789123456789&quot;

I should get the following list:

    [1234567891,2345678912,3456789123,4567891234,5678912345,6789123456,7891234567,8912345678,9123456789]

I&#39;ve found references to a &quot;lookahead&quot;, but the examples I&#39;ve seen only show pairs of numbers rather than larger groupings and I haven&#39;t been able to convert them beyond the two digits.

I have found very similar posts, but I can&#39;t quite get my regular expression right here.

I am trying to write a regular expression which returns a string which is between two other strings. For example: I want to get the string which resides between the strings &quot;cow&quot; and &quot;milk&quot;.

&gt; My cow always gives milk

would return

&gt; &quot;always gives&quot;

Here is the expression I have pieced together so far:

    (?=cow).*(?=milk)

However, this returns the string &quot;cow always gives&quot;.




Regular expression to get a string between two strings in Javascript

Greetings

When setting a summary for a property / field / method etc.. is it possible to have a newline in it?

    /// &lt;summary&gt;
    /// This is line 1
    /// This is line 2
    /// &lt;/summary&gt;
    public bool TestLine { get; set; }

When I set this it shows as on mouse over:

&gt;     bool TestLine
&gt;     This is line 1 This is line 2

But I want it to show as:

&gt;     bool TestLine
&gt;     This is line 1 
&gt;     This is line 2

I&#39;ve tried using `\n` but that doesn&#39;t work. Is there any way to get this done?



NewLine in object summary

Specifically I&#39;m interested in `istream&amp; getline ( istream&amp; is, string&amp; str );`. Is there an option to the ifstream constructor to tell it to convert all newline encodings to &#39;\n&#39; under the hood? I want to be able to call `getline` and have it gracefully handle all line endings.

**Update**: To clarify, I want to be able to write code that compiles almost anywhere, and will take input from almost anywhere. Including the rare files that have &#39;\r&#39; without &#39;\n&#39;. Minimizing inconvenience for any users of the software.

It&#39;s easy to workaround the issue, but I&#39;m still curious as to the right way, in the standard, to flexibly handle all text file formats.

`getline` reads in a full line, up to a &#39;\n&#39;, into a string. The &#39;\n&#39; is consumed from the stream, but getline doesn&#39;t include it in the string. That&#39;s fine so far, but there might be a &#39;\r&#39; just before the &#39;\n&#39; that gets included into the string.

There are [three types of line endings](http://en.wikipedia.org/wiki/CRLF#Representations) seen in text files:
&#39;\n&#39; is the conventional ending on Unix machines, &#39;\r&#39; was (I think) used on old Mac operating systems, and Windows uses a pair, &#39;\r&#39; following by &#39;\n&#39;.

The problem is that `getline` leaves the &#39;\r&#39; on the end of the string.

    ifstream f(&quot;a_text_file_of_unknown_origin&quot;);
    string line;
    getline(f, line);
    if(!f.fail()) { // a non-empty line was read
       // BUT, there might be an &#39;\r&#39; at the end now.
    }

**Edit** Thanks to Neil for pointing out that `f.good()` isn&#39;t what I wanted. `!f.fail()` is what I want.

I can remove it manually myself (see edit of this question), which is easy for the Windows text files. But I&#39;m worried that somebody will feed in a file containing only &#39;\r&#39;. In that case, I presume getline will consume the whole file, thinking that it is a single line!

.. and that&#39;s not even considering Unicode :-)

.. maybe Boost has a nice way to consume one line at a time from any text-file type?


**Edit** I&#39;m using this, to handle the Windows files, but I still feel I shouldn&#39;t have to! And this won&#39;t fork for the &#39;\r&#39;-only files.

    if(!line.empty() &amp;&amp; *line.rbegin() == &#39;\r&#39;) {
        line.erase( line.length()-1, 1);
    }

I need a conversion utility/script that will convert a .sql dump file generated on Mac to one readable on Windows.  This is a continuation of a problem I had [here][1].  The issue seems to be with newline formatting in text files, but I can&#39;t find a tool to make the conversion...

Converting newline formatting from Mac to Windows

Right now I&#39;m doing a `split` on a string and assuming that the newline from the user is `\r\n` like so:

    string.split(/\r\n/)

What I&#39;d like to do is split on either `\r\n` or just `\n`.

So how what would the regex be to split on either of those?

Trim spaces from end of a NSString

I&#39;m calling a REST API and am receiving an XML response back. It returns a list of a workspace names, and I&#39;m writing a quick `IsExistingWorkspace()` method. Since all workspaces consist of contiguous characters with no whitespace, I&#39;m assuming the easiest way to find out if a particular workspace is in the list is to remove all whitespace (including newlines) and doing this (XML is the string received from the web request):

    XML.Contains(&quot;&lt;name&gt;&quot; + workspaceName + &quot;&lt;/name&gt;&quot;);

I know it&#39;s case-sensitive, and I&#39;m relying on that. I just need a way to remove all whitespace in a string efficiently. I know RegEx and LINQ can do it, but I&#39;m open to other ideas. I am mostly just concerned about speed.



Efficient way to remove ALL whitespace from String?

I&#39;m using Ubuntu and I&#39;m also using Geany and CodeBlock as my IDE.
What I&#39;m trying to do is reading a string (like `&quot;Barack Obama&quot;`) and put it in a variable:

&lt;!-- language: c --&gt;

    #include &lt;stdio.h&gt;
    
    int main(void)
    {
    	char name[100];

    	printf(&quot;Enter your name: &quot;);
    	scanf(&quot;%s&quot;, name);
    	printf(&quot;Your Name is: %s&quot;, name);

    	return 0;
    }

Output:

&lt;!-- language: none --&gt;

    Enter your name: Barack Obama
    Your Name is: Barack

How can I make the program read the whole name?

c# Fastest way to remove extra white spaces

I am using iframes in my page, and have stumbled across a weird issue. I set the iframe css like so

    iframe {
        margin: none;
        padding: none;
        background: blue; /* this is just to make the frames easier to see */
        border: none;
    }
However, there is still whitespace surrounding the iframe. I tested it in both Chrome and Firefox, and it&#39;s the same. I searched around, and I couldn&#39;t find anything. This whitespace doesn&#39;t show up in the Chrome console, either.
Also, I already have the following CSS as well:

    html, body {
        margin: 0px;
        padding: 0px;
        border: 0px;
        width: 100%;
        height: 100%;
    }
