javascript - Regex to capture typed information in TypeScript -

-

I am new to reggax, have taken some tutorials, it is a tough time to get this right.

I am working on language support for type-script for a text editor, and I need a regedx that matches the information of typing in a function. For example: 

  function asdf (param1: type1, param2: type2, param3: type3) {...}   
 In that, my regex Match 'Type 1', 'Type 2', 'Type 3' etc.  
 Here's what I'm trying to do:  
  \? (??: (\ W).? \)   
 Breaks like this:  
  \ ( look for starting brackets  
 .   
  (\ w)  Capture group: Next word  
   
  \)  For brackets to the end of the function parameters Stop it.  
 Not sure what I'm doing wrong, but like I said I'm new to regx again. At present, it captures the entire stuff, from starting the legs to the feet to close. I need to match only one word after the colon.  
 Note: I want to make sure that it only matches the words after the calls within the carons so that it can not match the object key / data combos, which  < P>   
 
 
 Try this type  
  var STRIP_COMMENTS = / ((\\\\\\\\\\\\\\\\\\\\\\\ ************************************************************************** *************************** ARGUMENT_NAMES = / ([^ \ s,] +) / g; Function getParamNames (func) {var fnStr = func.toString (). (STRIP_COMMENTS, '') var results = fnStr.slice change (fnStr.indexOf ('(') + 1, fnStr.indexOf (')')). Match (ARGUMENT_NAMES) if (results === no L) Result = [] for (i = 0; i & lt; result.lamp; i ++) result [i] = result [i] .split (":") [1]; return result}  
  getParamNames ("function asdf (param1: type1, param2: type2, param3: type3) {...}");

python - Receiving "KeyError" after decoding json result from url -

-
I am new to Python I am trying to parse JSON result from a URL. Basically, I was using the following: response = urllib.request.urlopen (url) json_obj = json.load (response) It should be a stroke "str 'not' bytes' in the lines of a given" JSON object, so after searching on the StackoverView Flo, I decode the response in this way: F = urllib.request.urlopen (Url) charset = f.info (). Get_param ('charset', 'utf8') data = f.read () decoded = json.loads (data.decode (charset)) If I print "decode" I is as follows: { 'link': { 'summary data': 'https: // localhost / piwebapi / streams / p0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / summary' 'value': 'https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / price ',' InterpolatedData ':' https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTE...

.net - Creating a new Queue Manager and Queue in Websphere MQ (using C#) -

-
"itemprop =" text "> I am writing applications that use WebSphere MQ to send messages. My unittests (for flow), I want to verify that I have put the correct message on the response queue. I am trying to figure out how to do this. My main obstacle is that I think it might be scary to clear the queue before running in my queue because the same queue can be used by other applications, I thought a decent solution would be a new line The manager will remove the queue for my solidarity and after using it. So my question is: Is it possible to use C # by using queue manager and queue? After the For future reference and future people, who want to make queues. I thought how to make and remove IBM MQ QE (not quenhers) with PCM messaging. It is not very simple, but it can be done. We have implemented it in a library and it is being used to create and delete commands before and after integration tests. The most important part of the code in this library is shown in the...
