The following should suffice:

    [^ ]

If you want to expand that to anything but white-space (line breaks, tabs, spaces, hard spaces):

    [^\s]

or

    \S  # Note this is a CAPITAL &#39;S&#39;!

- `\s` matches any white-space character
- `\S` matches any non-white-space character
- You can match a space character with just the space character;
- `[^ ]` matches anything but a space character.

Pick whichever is most appropriate.

I can find a way to send parameters to my activity from my notification.

I have a service that creates a notification. When the user clicks on the notification I want to open my main activity with some special parameters. E.g an item id, so my activity can load and present a special item detail view. More specific, I&#39;m downloading a file, and when the file is downloaded I want the notification to have an intent that when clicked it opens my activity in a special mode. I have tried to use `putExtra` on my intent, but cant seem to extract it, so I think I&#39;m doing it wrong.


Code from my service that creates the Notification:

            // construct the Notification object.
         final Notification notif = new Notification(R.drawable.icon, tickerText, System.currentTimeMillis());


		final RemoteViews contentView = new RemoteViews(context.getPackageName(), R.layout.custom_notification_layout);
		contentView.setImageViewResource(R.id.image, R.drawable.icon);
		contentView.setTextViewText(R.id.text, tickerText);
		contentView.setProgressBar(R.id.progress,100,0, false);
		notif.contentView = contentView;		
		
		Intent notificationIntent = new Intent(context, Main.class);
		notificationIntent.putExtra(&quot;item_id&quot;, &quot;1001&quot;); // &lt;-- HERE I PUT THE EXTRA VALUE
		PendingIntent contentIntent = PendingIntent.getActivity(context, 0, notificationIntent, 0);
		notif.contentIntent = contentIntent;
        
        nm.notify(id, notif);


Code from my Activity that tries to fetch the extra parameter from the notification:


     public void onCreate(Bundle savedInstanceState) {
    	super.onCreate(savedInstanceState);
    	
        setContentView(R.layout.main);

        
        Bundle extras = getIntent().getExtras();
        if(extras != null){
        	Log.i( &quot;dd&quot;,&quot;Extra:&quot; + extras.getString(&quot;item_id&quot;) );
        }


The extras is always null and I never gets anything into my log.

Btw... the `onCreate` is only run when my activity starts, if my activity is already started I  also want to collect the extras and present my activity according to the item_id I receive.


Any ideas?

How to send parameters from a notification-click to an activity?

Let&#39;s say I have a script like the following:

useless.sh

    echo &quot;This Is Error&quot; 1&gt;&amp;2
    echo &quot;This Is Output&quot; 

And I have another shell script:

alsoUseless.sh

    ./useless.sh | sed &#39;s/Output/Useless/&#39;

I want to capture &quot;This Is Error&quot;, or any other stderr from useless.sh, into a variable. 
Let&#39;s call it ERROR.

Notice that I am using stdout for something. I want to continue using stdout, so redirecting stderr into stdout is not helpful, in this case.

So, basically, I want to do

    ./useless.sh 2&gt; $ERROR | ...

but that obviously doesn&#39;t work.

I also know that I could do

    ./useless.sh 2&gt; /tmp/Error
    ERROR=`cat /tmp/Error`

but that&#39;s ugly and unnecessary.

Unfortunately, if no answers turn up here that&#39;s what I&#39;m going to have to do.

I&#39;m hoping there&#39;s another way.

Anyone have any better ideas?

How to store standard error in a variable

I need to match a single character that is anything but a space but I don&#39;t know how to do that with regex.

regex to match a single character that is anything but a space

<p>I need to match a single character that is anything but a space but I don't know how to do that with regex.</p>


If I have a string like &quot;something12&quot; or &quot;something102&quot;, how would I use a regex in javascript to return just the number parts?

Regex using javascript to return just numbers

Here is a design though: For example is I put a link such as

&gt; http://example.com

in **textarea**. How do I get PHP to detect it’s a `http://` link and then print it as

    print &quot;&lt;a href=&#39;http://www.example.com&#39;&gt;http://www.example.com&lt;/a&gt;&quot;;

*I remember doing something like this before however, it was not fool proof it kept breaking for complex links.*

Another good idea would be if you have a link such as

&gt; http://example.com/test.php?val1=bla&amp;val2blablabla%20bla%20bla.bl

fix it so it does

    print &quot;&lt;a href=&#39;http://example.com/test.php?val1=bla&amp;val2=bla%20bla%20bla.bla&#39;&gt;&quot;;
    print &quot;http://example.com/test.php&quot;;
    print &quot;&lt;/a&gt;&quot;;

This one is just an after thought.. stackoverflow could also probably use this as well :D

Any Ideas

Replace URLs in text with HTML links

In `C#`, I want to use a regular expression to match any of these words:

    string keywords = &quot;(shoes|shirt|pants)&quot;;

I want to find the whole words in the content string.  I thought this `regex` would do that:  

    if (Regex.Match(content, keywords + &quot;\\s+&quot;, 
      RegexOptions.Singleline | RegexOptions.IgnoreCase).Success)
    {
        //matched
    }

but it returns true for words like `participants`, even though I only want the whole word `pants`.  

How do I match only those literal words?

Regex.Match whole words

Here is the case:
I want to find the elements which match the regex...

&gt; targetText = &quot;SomeT1extSomeT2extSomeT3extSomeT4extSomeT5extSomeT6ext&quot;

and I use the regex in javascript like this

    reg = new RegExp(/e(.*?)e/g);   
    var result = reg.exec(targetText);

and I only get the first one, but not the follow....
I can get the T1 only, but not T2, T3 ... ...

How to loop all the elements that match the regex?

I have a string, such as `hello _there_`. I&#39;d like to replace the two underscores with `&lt;div&gt;` and `&lt;/div&gt;` respectively, using **JavaScript**. The output would (therefore) look like `hello &lt;div&gt;there&lt;/div&gt;`. The string might contain multiple pairs of underscores.

What I am looking for is a way to **either** run a function on each match, the way Ruby does it:

    &quot;hello _there_&quot;.gsub(/_.*?_/) { |m| &quot;&lt;div&gt;&quot; + m[1..-2] + &quot;&lt;/div&gt;&quot; }


**Or** be able to reference a matched group, again the way it can be done in ruby:

    &quot;hello _there_&quot;.gsub(/_(.*?)_/, &quot;&lt;div&gt;\\1&lt;/div&gt;&quot;)

Any ideas or suggestions?
