  • Objective C - RegexKitLite - Parsing inner contents of a string, ie: start(.*?)end

    - by Stu
    Please consider the following: NSString *myText = @"mary had a little lamb"; NSString *regexString = @"mary(.*?)little"; for)NSString *match in [myText captureComponentsMatchedByRegex:regexString]){ NSLog(@"%@",match); } This will output to the console two things: 1) "mary had a little" 2) "had a" What I want is just the 2nd bit of information "had a". Is there is a way of matching a string and returning just the inner part? I'm fairly new to Objective C, this feels a rather trivial question yet I can't find a less messy way of doing this than incrementing an integer in the for loop and on the second iteration storing the "had a" in an NSString.

  • PulpCore OGG music playback - can't loop as soon as I animate the musicVolume property

    - by Peter Perhác
    I have been experimenting with PulpCore for about a week or so and I am enjoying it very much but today I ran into a problem that I can't quite figure out. Sound bgMusic = Sound.load("music/music.ogg"); Playback musicPlayback; ... musicVolume = new Fixed(0.75); musicPlayback = bgMusic.loop(musicVolume); //TODO figure out why it's NOT looping when volume is animated // musicVolume.animate(0, musicVolume.get(), FADE_IN_TIME); This code, for as long as the last line is commented out, plays the music.ogg again and again in an endless loop (which I can stop by calling stop on the Playback object returned from loop(). However, I would like the music to fade in smoothly, so following the advice of the PulpCore API docs, I added the last line which will create the fade-in but the music will only play once and then stop. I wonder why is that? Here is a bit of the documentation: Playback pulpcore.sound.Sound.loop(Fixed level) Loops this sound clip with the specified volume level (0.0 to 1.0). The level may have a property animation attached. Parameters: level Returns: a Playback object for this unique sound playback (one Sound can have many simultaneous Playback objects) or null if the sound could not be played. So what could be the problem? I repeat, with the last line, the sound fades in but doesn't loop, without it it loops but starts with the specified 0.75 volume level.

  • Code hot swapping in Erlang

    - by Roger Alsing
    I recently saw a video about Erlang on InfoQ, In that video one of the creators presented how to replace the behavior of a message loop. He was simply sending a message containing a lambda of the new version of the message loop code, which then was invoked instead of calling the old loop again. Is that code hot swapping in Erlang reffers to? Or is that some other more native feature?

  • Get number of times in loop over Hash object

    - by Matt Huggins
    I have an object of type Hash that I want to loop over via hash.each do |key, value|. I would like to get the number of times I've been through the loop starting at 1. Is there a method similar to each that provides this (while still providing the hash key/value data), or do I need to create another counter variable to increment within the loop?

  • How to commit inside a CURSOR Loop?

    - by user320587
    Hi, I am trying to see if its possible to perform Update within a cursor loop and this updated data gets reflected during the second iteration in the loop. DECLARE cur CURSOR FOR SELECT [Product], [Customer], [Date], [Event] FROM MyTable WHERE [Event] IS NULL OPEN cur FETCH NEXT INTO @Product, @Customer, @Date, @Event WHILE @@FETCH_STATUS = 0 BEGIN SELECT * FROM MyTable WHERE [Event] = 'No Event' AND [Date] < @DATE -- Now I update my Event value to 'No Event' for records whose date is less than @Date UPDATE MyTable SET [Event] = 'No Event' WHERE [Product] = @Product AND [Customer] = @Customer AND [Date] < @DATE FETCH NEXT INTO @Product, @Customer, @Date, @Event END CLOSE cur DEALLOCATE cur Assume when the sql executes the Event column is NULL for all records In the above sql, I am doing a select inside the cursor loop to query MyTable where Event value is 'No Event' but the query returns no value even though I am doing an update in the next line. So, I am thinking if it is even possible to update a table and the updated data get reflected in the next iteration of the cursor loop. Thanks for any help, Javid

  • Synergy: avoid single machine loop when client is not connected

    - by petobens
    In order to loop between my screens I have the following section in my synergy.sgc file: section: links Pedro-Acer: right = pedro-lubuntu left = pedro-lubuntu pedro-lubuntu: left = Pedro-Acer right = Pedro-Acer end With those settings When the client disconnects the server screen wraps around itself as seen in the image below. I don't want this behavior. The only reason I set the config file to loop between my screens is because I want to have a single key to switch between them: keystroke(alt+`) = switchInDirection(right) If there is way to have a single key for switching in both directions without having looping screens then that would also solve my problem.

  • How to kill all screens that has been up longer then 3 weeks?

    - by Darkmage
    Im creating a script that i am executing every night at 03.00 that will kill all screens that has been running longer than 3 weeks. anyone done anything similar that can help? If you got a script or suggestion to a better method please help by posting :) I was thinking maybe somthing like this. First do a dump to textfile ps -U username -ef | grep SCREEN dump.txt then do a loop running through all lines of dump.txt with a regex and putting pid of the prosseses with STIME 3weeksago in a array. then do a kill loop on the array result.

  • Connecting server to more than one switch.

    - by Jake
    I have 3 switches, one NEATGEAR GS748T and two JGS524. Initially I wanted to connect them in a triangle loop, but later suspect that the JG524 does not have spanning tree support. Now I have a Dell R710 with 2 NIC at the back. If I connect the server in between the two JGS524, which both in turn connect to the GS748T, will that consitute a loop? According to my limited understanding, with 2 NICs there will be 2 IPs for the server. Will the file server even work or not? Theoretically speaking, will this configuration increase the access speeds for clients? Thanks.

  • Referring to a non-final variable data inside an inner class

    - by shoaibmohammed
    Im doing a program in GWT. Here is the snippet where Im having problem private String[] populateRSSData() { 1==>> String[] data = null; try { new RequestBuilder(RequestBuilder.GET, "../database.php?action=populaterss").sendRequest(null, new RequestCallback() { @Override public void onResponseReceived(Request request, Response response) { 2==>> data=response.getText().split("~"); } @Override public void onError(Request request, Throwable exception) { Window.alert(exception.getMessage()); } }); } catch (RequestException e) { Window.alert(e.getMessage()); } return data; } Now the problem arises that I get an error that the variable 1==>> data should be declared final. But if I declare it as final then i cannot store the datas in 2==>> The error i get Cannot refer to a non-final variable data inside an inner class defined in a different method RSS_Manager.java Please suggest

  • Passing arguments to anonymous inner classes

    - by synic
    I'm trying to make an API library for our web services, and I'm wondering if it's possible to do something like this: abstract class UserRequest(val userId: Int) { def success(message: String) def error(error: ApiError) } api.invokeRequest(new UserRequest(121) { override def success(message: String) = { // handle success } override def error(error: ApiError) = { // handle the error } } I'm talking about passing parameters to the anonymous inner class, and also overriding the two methods. I'm extremely new to Scala, and I realize my syntax might be completely wrong. I'm just trying to come up with a good design for this library before I start coding it. I'm willing to take suggestions for this, if I'm doing it the completely wrong way, or if there's a better way. The idea is that the API will take some sort of request object, use it to make a request in a thread via http, and when the response has been made, somehow signal back to the caller if the request was a success or an error. The request/error functions have to be executed on the main thread.

  • Int PK inner join Vs Guid PK inner Join on SQL Server. Execution plan.

    - by bigb
    I just did some testing for Int PK join Vs Guid PK. Tables structure and number of records looking like that: Performance of CRUD operations using EF4 are pretty similar in both cases. As we know Int PK has better performance rather than strings. So SQL server execution plan with INNER JOINS are pretty different Here is an execution plan. As i understand according with execution plan from attached image Int join has better performance because it is taking less resources for Clustered index scan and it is go in two ways, am i right? May be some one may explain this execution plan in more details?

  • Access inner function variables in Javascript

    - by Elazar Leibovich
    In many frameworks, internal function variables are used as private variables, for example Raphael = (function(){ var private = function(a,b) {return a+b;}; var public = function(a) {return private(a,a);} var object = {mult2:public}; return object; })(); here, we cannot access from the global namespace the variable named private, as it is an inner variable of the anonymous function in the first line. Sometimes this function is contains a big Javascript framework, so that it wouldn't pollute the global namespace. I need to unit tests some object Raphael uses internally (in the above example, I wish to run unit tests on the object private). How can I test them?

  • conditional while loop in php?

    - by julio
    I'm pretty sure there's an obvious answer for this-- hoping someone can help me-- I need to do a PHP while loop, but only if a variable is true. And I can't really put the while loop in an "if" statement, which seems like the obvious thing to do, since the code block is huge and it would be ugly and confusing. Do I need to break out the code in the loop into a function, or is there an easier way to deal with this? Here's the basic idea: if(condition){ while(another_condition){ //huge block of code loops many times } } else { // huge block of code runs once } I want the huge block of code to execute regardless of the state of the condition variable-- but only to execute once if condition is false, and execute for as long as another_condition is true if condition is true. Hope that's clear! The following code doesn't work, but gives an idea of what I want to accomplish: if(condition){ while(another_condition){ } // huge block of code if (condition){ } } // closes the while loop-- obviously throws an error though! thanks in advance.

  • How to make sure the value is reset in foreach loop in PHP

    - by kwokwai
    Hi all, I was writing a simple PHP page and a few foreach loops were used. Here are the scripts: $arrs = array("a", "b", "c"); foreach ($arrs as $arr) { if(substr($arr,0,1)=="b") { echo "This is b"; } } // ends of first foreach loop and I didn't use ifelse here And when this foreach ends, I wrote another foreach loop in which all the values in the foreach loop was the same as previous foreach. foreach ($arrs as $arr) { if(substr($arr,0,1)=="c") { echo "This is c"; } } I am not sure if it is a good practice to have two foreach loops with same values and keys. Will the values get overwritten in the first foreach loop?
