Jquery Show/Hide Toggle -

I am trying to recreate the effect shown on the BBC homepage where links 'add more to this page' and 'Set Location' slides open their respective devices and show their relevant content. If you choose 'Add more on this page' then it opens the 'Add more' section. If you select 'Add more on this page' then the 'Add more' section closes, however, if the 'Add more' section is open, and you select 'Set Location' then this 'Set Location' Slides the 'Add more' section before sliding down. I have managed to regenerate this effect using the following code: HTML jQuery code $ (function () {$ ("# siteCustomization .siteSelection") Hide (); $ ("# Demo Li One "$ {$ Id = $ (this) .attr ('href'); var $ thisDiv = $ (id); if ($ thisDiv. Siblings (': visible') length) {$ thisDiv.siblings ( ': View'.) SlideUp (700, function () {$ thisDiv.slideDown ();});}. Else {$ th

c# - Should one extend or encapsulate ORM objects? -

I have a problem understanding the use of ORM created objects. We are using LLBLGen for mapping our database model objects. It might be better to code this code. Our application as public class book {// Class used in the Private BookEntity book; // LLBLGen unit Private BookType bookType; // BookType is another class that wraps an entity's public book {ENT EID} {book = new BookEntity (ID); } Public BookType BookType {get {return.bookType; } Set {this.bookType = value; This.book.BookType = New BookTypeEntity (value.ID); This.book.Save (); }} Public Integer Calculation Page () {} Business Method of Example} It is strange to highlight the areas of the institution such as properties, because I am mapping again list-types With this it is very bad, because I have to write an "add" and "remove" method and a property that displays the property. In the above example, I need access to the BookType Setter BookTypeEntity object, I can get this object by using a

objective c - Defeating the "multiple methods named 'xxx:' found" error -

In my existing project in File ViewController.m, I am running the method: [[Connection Writer] Write Data: Data]; This warns: Warning: Several methods were found in the name of 'writeData:' I To call the method trying to: - (zero) write data: TCPRIR in (NSDT *) data .... M. Unfortunately, there are two other writing data methods - (zero) write data: (NSDT *) data; ... nsfile in handheld and ... - Writing data: (NSDT *) data ... in NSURLHandle.h. This is especially confusing to me because the [conn writer] should return the TCPWriter class and correct that class to the right writeData method Besides calling, I am not entirely sure that NSFillHandleH and NSURHRWHDLH have been included in any library included in the visual controller instead of any part of the project. How can I show the compiler that I want to call the writeData method and why is this error? Be sure that [connection author] is actually returning a TCPWriter * if i

JavaScript error on FireFox ns_error_dom_security_err -

I'm getting the following error in Firefox: Error: [exception. "Security Error" code: "1000" nsresult: "0x805303e8 (NS_ERROR_DOM_SECURITY_ERR) " location: ""] I know that with the help of a CSS call What to do Thanks! Greg Wilson PS: If this is from another domain, but I can not find any reference for any domain! is a duplicate, I'm sorry. I thought I posted yesterday but it did not get it. I had this problem with Firefox when I included a line like this in jQuery: & lt; Script type = "text / javascript" src = "/ javascript / jquery-1.4.2.min.js" & gt; & Lt; / Script & gt; But then I had a script that used jQuery in this way: When I changed the "type" attribute of the second line to "text / javascript", then it is included, the error has ended. It appears to be some type of security feature, where script type must match before referencing each other.

asp.net - IHttpHandler for images producing a stackoverflow in IE -

I have a directory of images located outside the context of my web application which I need to serve the user I currently I'm using IHttpHandler to serve images and using some javascript to navigate through a set of images (navigation is now primitive). I use the examples IHttpHandler uses to illustrate the images closely, but when I look at the images in Firefox hanging in the browser and when I look in IE, I get the "Stack overflow line: 0" < / p> IHttpHandler code public class ShowImage: (ByVal context as HttpContext) Implements IHttpHandler public sub ProcessRequest _ Implements IHttpHandler.ProcessRequest picid be as dim string Contekstkrikvest.

iphone - Is it possible to create a CGBitmapContext with a CMYK colorspace and draw into it? -

I am trying to create a bitmap contact with the CMYK colorspace and draw a picture in it. I am using code from Apple's Q & A, and it has been modified to draw it in the shape of CMYK and draw it in it. In my logs, I get an error Unsupported pixel details - 4 components, 8 bit-per-component, 32-bit-per-pixel and I get an empty reference What am I missing?

javascript - Equivalent of String.format in jQuery -

I'm trying to move some javascript code from MicrosoftAjax to JQuery. I use Microsoft's JavaScript counterparts in popular NET methods, e.g. String.format (), String.startsWith (), etc. Do they have similarity in jQuery? For your reference, so that you can choose through it and include those parts Want to continue to use it in a different JS file. Or, you can port them on jQuery. Here is the format function ... string.format = function () {var s = arguments [0]; For (var i = 0; i & lt; arguments.length - 1; i ++) {var reg = New RegExp ("\\ {+ +" + "\\}", "GM"); S = s.replace (reg, argument [i + 1]); } Return S; } and end here and begins with prototype functions ... string.prototypeands = function (suffix) {return (this .substr (This.length - suffix.length) === suffix); } String.prototype.startsWith = function (prefix) {return (this substr (0, prefix.length) === prefix); }

I am working on a web page that uses dojo and I have a number (my trial cases In 6, but in general variables) I'm calling dojo.addOnLoad (init) of the project widget, and my init () function has these lines: dojo.connect (Dijit.byId ("project" + 0).

c# - Building .NET COMInterop project without first registering the COM service -

I am creating a C # UI for interacting with a COM service (.exe) The VS 2005 com project produces a valid typelist (TLB), which is referred to by the C # project. However, the VS 2005 C # project says that the service can be registered to create a C # project, even if Typelib is fully valid during testing of the open object viewer. We will not register the service instead of the build server, if possible, the debug build can not register a COM object as a service, because it normally does debugging, and Especially the startup code is more difficult (F5 - debugging can not be started). What should I look for to get this job done? Do I Just Need To Register TypeLib? If so, why would it be said for emphasizing the service or TLB registration to build COMInterop properly (and, is it a command line tool with VS 2005 on Win2003)? At one time I created a C # web service that refers to the Win2003 firewall COM object, but we do not recommend it Win2000 (which is not such a thing) onl

c# - WCF - Cannot resolve [WebGet] symbol - what am I doing wrong? -

I am working on a rest WCF project and when I apply the following code, it complains that Can not solve this WebGet class? What am I missing? I tried to import the system. Servicemodel. Web name space but I can not refer to it, though I refer to it. "Web" in System.ServiceModel.Web, when I register in a statement being used at the top of my code, it is not registered. Actually, I need to apply such WCF reef concepts such as WebGet, WebInvok, Urememplate, etc.? Update: After thinking about some feedback and thinking about it, I think that what DLL (System.ServiceModel & System) .ServiceModel .Web) When I go to add a project reference do not come through the 'Add Reference' window. When I first started the project, FYI, because these assemblies did not come for the first time, I was searching for them, and copied them to a temporary folder so that I could refer them and thus, I think That's the issues to solve me. So, now that I am at this point, how

optimization - Keeping your code in L1 cache -

I am reading and I have seen it: small size language interpreter And compact syntax makes it possible for applications to fit within the processor level 1 cache. I am afraid how is the whole program possible in L1 cache? Say, the CPU has 256kb L1 cache. Say that my program is less than that and needs a lot of memory (say, just call stack and so on) It does not require any libraries (although a program is for OS, it must include kernel32.dll or anything). Thanks "post-text" Itemprop = "text"> I think what they are saying is not that the whole program fits in the L1 cache, but that all the code that runs most of the time fits in the L1 cache . Yes, the OS allocates many other structures, but it does not matter. Of course, all this is speculation - I do not know anything about 'Kashmir' language.

about background attribute in css -

background: # 777777 scroll no repeat 0 0; There are 5 features included in the background color, background-image, background-repeat, background-attachment and background-position. But I do not understand what the background-attachment and background-position is? Can someone give an explanation? Edit : Background-repeat, background-attachment, and background-condition are useless if there is no background-image? If you've ever seen a web page where the text on the page scrolls with scrollbar, but the background Stable, he background-attachment: fix; The background-condition defines how you present the image inside the background of the element. For example, if you have a droplet shadow image that repeats only at the bottom edge of your element, then you can use it: background-repeat: repeat x; Background-position: bottom left; Or if you had an image, you just wanted to show it in the bottom-right corner of your element: Back-to-back: bottom Right;

networking - how to dispatch network requests to the (geographically) closest server -

I am a Java code and is not very familiar with how the network works (except for the original UDP / TCP connections) says that there are servers running on machines in the US, Asia, Latin America and Europe. When a user requests a service, I request them to visit the nearest server to them. Is it possible to have an address for me: mycompany.com, and receive any request sent to the appropriate server? Apparently when someone goes to CNN.com, they receive photos, videos, etc. from a nearby server. Frankly, I do not think how it works. Anyway, my servers do not serve web pages, they serve other services like stock market data ... just in that situation. Since I am a programmer, I am interested in knowing how it will work in software. Since this is slightly more than a worthless curiosity, the signs of commercial products or services will not be very useful in understanding this problem :) A simple approach The first byte (class A) of the IP address should be seen after U

c# - Server side event confusion with ASP.NET -

I am trying to create a web page that uses a user to access images from the server connected to the server using ASP Will allow captivity. met. The camera is an Olympus and the server side code has access to all synchronous calls which are in the camera's SDK. The problem occurs when I try to capture an image. The way this works works SDK is that for the first time you tell the camera to take the image, then to add an audience to an event that triggers the camera, once the image is After capturing the camera starts downloading the image. The event is never triggered, so I am currently unable to download the image from the camera. A camera tells the listener a camera to take the code and picture in the function, it is within the server side code of the button. Basically I'm wondering how to become an event listener for a person who changes on the server, such as the position of the camera. > I hope you have problems with it. For example, I'm sure the camera beli

php - Regular expressions / parsing dig output / extracting text from double quotes -

I need help finding some regular expressions. I am running the dig command and I have to use its output. I need to parse it and organize it systematically as an ARP php. The dig makes something like this: m0.ttw.mydomain.tel. TXT ".tkw" "in 60" "1" "20090624-183342" "some text here 1" m0.ttw.mydomain.tel. 60 in TXT ".kk" "1" "200 9 624-183341" "some text here 2" I have to do this: Array ([0] = & gt; Array ([0] = & gt; .kk [1] => 1 [2] => 20090624-183342 [3] = & gt; some text here 1) [ 1] = & gt; Arr .. ..) I only need the contents of double quotation marks. I can do parse the output line dug by line I do, but I think it will be faster if I run regex patterns on it all ... Thoughts? it stops with a line preg_match_all ( '/' ([^ "] +)" \ S * "([^"] +) "\ s *" ([^ "] +)" \ s * "([^"] + / '

I want to select all the elements that have two classes a and b . & lt; Element class = "ab" & gt; So, only those elements are both classes. When I $ (".

If you want intersection, just select the selectors simultaneously without spaces Type $ ('a.b') An element for which there is an ID with a classes < Code> B and C , you will type: $ ('# abc') < / Html>

sharepoint - WSS 2.0 web site all the list edit function doesn't work suddently -

I have found this program, editing SharePoint does not work in all the lists of websites, I can still access "Edit", and save it, but the change is not there, the new thing can be made, all other than editing looks fine. Any help will be very much appreciated. This is unusual ... and unfortunately WSS 2.0 does not give much logging. Are there any errors that are being reported in the application log of the application viewer on the server? This permission can also be done. What kind of list is this? If this is an issue list then something went wrong in the list view which is hiding the recent changes.

c# application encountering a problem and closing for no apparent reason. Possible problems with 3rd party dlls -

We are building a C # application that will sit in the PC trash truck. Things work fine on our development machines, but like always, when we work on our target hardware then problems start. One of the specially giving us headache. At random intervals, we will lift the message box of a window and say that there is a problem in our application and it needs to be closed. The app still works fine, while the dialog box is sitting there, and obviously it closes when you click on the Close button. The disappointing thing is that we do not get any exceptions, nothing in any log, nothing in the system activity log. I have a queue that there is a problem in a third party library that we use for GPS There is a pure cover for unmanaged DLL which we already have problems. What do we have to try and debug ?? I am relatively new to Windows programming and am wondering if there are programs, we can use to know that the part of which DLL portion is being called by our code. Cheers Nimai

How to join multiple tables with one to one relationships in rails -

Ruby on Rail is very new to me. I'm trying to recover a set of columns from 3 different tables. I thought I could use the SQL View to retrieve my results, but there was no way to use the ideas in Rail. These are my tables 1) User table -> username, password and email 2) Usageetal table -> Foreign key: user_id, name, address 1, city etc. 3) Userwork version Description-> Foreign key: user_id, work address 1, work type etc. These 3 tables have one relation, then Table 2 comes under Table 1 and Table 3 also comes from the table. Is related. Table 1 contains a user's description and a user function. I want to get the user's email, name, address 1, city, work address 1, work type Join join What is the best way to handle it? is the data) Everything else in the model is just an optimization For example, address1 is defined as User.user_detail.address1 , for example. If you have a user with class user_detail: _ user_work_detail end class UserDetail is

c# - Invalid ContentPropertyAttribute on property 'Text' -

I'm having trouble setting up my content property in "text." The error I am given is: Invalid content property entry type 'MyType', property 'text' was not found. The code behind this looks like this: [ContentProperty ("text")] Public partial class MyType: UserControl {public MyType () {InitializeComponent (); } Public static read-only dependency form TextProperty = DependencyProperty.Register ("text", typef (string), typef (myType)); Public Stabilized String GetText (Dependency Object D) {Return (String) d.GetValue (TextProperty); } Public static zero SetText (dependent object D, string value) {d.SetValue (TextProperty, value); } Public string text {get {return (string) GetValue (TextProperty); } Set {set value (textproperty, value); }}} I have actually found it to work if I keep the name of the CLR property in addition to the dependency property - am I using dependency properties incorrectly ?

Create unique Poll/vote/survey in php -

Unique survey / vote / survey I mean that users can vote only once. How do I do that? Track their IP? log in? Besides the login, what else? (Entrance is my last option, so next to the entry, can I do anything?) < P> To limit the number of votes per person, you have to track the person. Now there are several ways to do this, and I list them with their professionals and opposition to decide which method you regard best. Login: This will give you ultimate control. But it is a bit cumbersome for the user. and your previous priority IP: How do you handle people behind the web proxy? How about people with dialup connections and / or dynamic IPs? Cookies: This is good for short term elections, so that you can set the end of the pole to the time the poll is finished. But, one potential flaw is how the user will remove cookies (opposite with A) cookies! openId : Although this method is not very different from 'login' method, it saves the user from registering

user interface - Is there a way to convert GUI in image to html? -

I have GUI screen shots from the design team, which I do not need to convert to a web page and what not. I'm thinking of finding some websites that look like GUI so that I can copy and paste html, so I do not have to start with scratch. The only drawback of this method is that I do not know what the website really looks like, which means that it means a lot of browsing time. Hehe So just wondering is there a tool that can help me find out? Or even better if there is an instrument that can convert the image into an HTML web page equivalent, then even better. I think I'm just another lazy random programmer trying to accelerate the part of Gui, hey. Thank you. You mean you have a PNG, GIF or JPG screen shot ... and you can call it a Want to feed in the program and want to leave a collection of HTML and CCS, which will look like that image when viewed in the browser? I apologize for the bursting of your bubble, but I would be very surprised, if this was the case.

c# - Best practices for getting around DB differences with an IDataReader -

I have a simple value object that I populate with data from idata reader (either for an oracle The query may be the result or MS SQL database). The factory method for this object looks like the following: Fixed some class CreateFromDataReader (IDataReader data) {string message = data.GetString (0); Short ID = data. GetInt 16 (1); Date Time = DateType = Data. Gateadet Time (2); Returned a new class (message, id, datestamp); } Then I went into a problem that is related to the difference in the data type, which uses the Oracle and MS SQL databases for that particular column: the data type in the oracle Number while lower id = convert. ToInt16 (now), when I can fix this problem: data.GetValue (1)); Is there a better or more excellent way to do this? I do not know how ORM does the focus of such a scenario. However, you should use a type that can accommodate both (all) cases for such an area. I saw; It seems that the decimal is the appropriate appropriate data type

asp.net - programmatically control output caching - disable or enable cache according to parameter value -

For us to endorse lists of our products within the categories fairly standard e-commerce landscape is better or worse, almost 80% of visitors never navigate according to the first page, depending on the category, then there can be 5-10 more pages of results, which have been seen in less time so far. (Yes we do appears on the first page are optimized and good looking - but it is a different discussion) We can not check every page of results, because we are constrained by memory , But the benefit of caching will only be bigger in the first page of the results of each category. I know that I can do something by using object caching to store the dataset in question, but it is possible using the output caching, perhaps using the feedback. Catch object? Where can this be done in the page life cycle? Pre-render? is very simple, the URL is "/ Product List" class = more page = 1 ", and I want some logic (eg pseudocode): if parameters Use "page" equal 1 ou

asp.net mvc - Do you check HttpVerbs in your unit tests? -

Standard ASP. Looking at the unit tests that come with the MVC Web project template I have seen that they do not check whether or not a proper HTVPARS attribute is set to every action method. It is easy to test this with reflection, but the question is whether it is worth the effort. Do you check HTTPVirbs in your unit test, or do you leave it for unity testing? You can also use MvcContrib.TestHelper to test route along the route. [TestMethod] Public Zero ShouldConfirmRouteForNewObjectWithPost () {"~ / Object / New" .WithMethod (HttpVerbs.Post). ShouldMapTo & lt; ObjectController & gt; (X => x.New ()); }

Time: (in seconds) [YSlow] 9.9 Gif Graham 3.1 hotskills.net 1.9 jeeyo.net 1.5 appspot.com Is this app engine cloud very slow, BigTable is too slow ... or what? You are using the YSlow plugin to measure it, and YSlow tells you that the site slows down Why is it (the name of smartness is clue). For example, in the case of gifttag.com, YSlow reports that: This page has 9 external javascript scripts, try combining them in one, this page has 3 external stylesheets Try combining them in one. Try this page to have 13 external background images to combine them with CSS sprites. Therefore it receives an 'E' grade for it to kill the site's alleged load performance. None of these have to do anything with appennin.

math - Why are the arguments to atan2 Y,X rather than X,Y? -

सी में atan2 फ़ंक्शन में निम्न हस्ताक्षर हैं: डबल एटैन 2 (डबल वाई, डबल एक्स); अन्य भाषाएं भी ऐसा करते हैं यह एकमात्र ऐसा कार्य है जो मुझे पता है कि वाई, एक्स ऑर्डर के बजाय वाई, एक्स ऑर्डर में अपनी बहस लेती है, और मुझे नियमित रूप से पेंच करते हैं क्योंकि जब मुझे लगता है कि निर्देशांक, मुझे लगता है (एक्स, वाई)। > क्या किसी को पता है कि क्यों एना 2 का तर्क आदेश सम्मेलन इस तरह से है? क्योंकि मुझे विश्वास है कि यह आर्कटॅन से संबंधित है (Y / x), इसलिए y शीर्ष पर दिखाई देता है। यहाँ एक अच्छा लिंक है जो कि इसके बारे में थोड़ा सा है:

Is it a good idea(tm) to use REST ideas to design 'some service' from the ground up? -

If you want to start a 'website' which may be accessible from many 'endpoint', from the beginning, a REST Is it a good idea to design perspective? I am thinking that the answer is yes ... but is there any other opinion? Is the 'starting point' for your system's design, which is relatively extensible and not defined in the way? Lesson "> I suggest that the best starting point is the data model, which is the most important factor to think about which data you will be storing and how it relates to other data Once a solid foundation has been set for the model, it exposes it to many additional consumers through REST, SOAP, RSS, ATOM, etc.

Accessing SQL Server from windows service -

I am trying to add SQL Server from a Windows service. Now my Windows service is installed in different systems. Now how can I connect if I want to connect to my SQL server? I am able to connect if I add the related system user ID to the SQL Server login user, I do not think this is the correct way .. Because I need to install the window service in different systems, Need to add in I think you are using InstallUtil to install the service. You must configure the service to run under the domain account. Let's call it in your Dain \ WindowsSecondadman account In the connection string, use the tag INTEGRATED SECURITY = SSPI On SQL Server, create a login YourDomain \ WindowsServiceDomanAccount and assign it to the appropriate Provide permissions. You must be configured for a remote connection to allow a non-local connection.

iPhone Dev: Playing back a flash animation -

I am creating a simple application that contains a few buttons when clicked while playing a video. Right now I have those videos as a flash file. For my first try, I tried to convert them. Used the MOV and Media Player framework. Video is very bad / and when you double click on video control pop up. I'm not sure what is the best way to do this. Is the media player wrong? Is there a better way? Here is an example of another app that is doing what I am doing exactly what I need. Crazy eye: thanks, matte media Player Framework should not affect the quality of your video, there is something that you should be addressing with the type of encoding options specified when converting the video. Since there is no flash on the iPhone, you have only one option that they want to convert them to an iPhone-friendly format, that is: "Supported formats: this class can be any Movie or audio files that are already in plays correctly on iPod or iPhone. This means that exten

actionscript 3 - Best way to reuse an element from an Array? -

I have an array of character objects (Sprite is extracted). Public Static Verlists: Array; When a character dies, I put a flag to give this sign. char.die = true; When I create a new player, to check the slot again, I check against this flag. This is where the problem arises. What is the best way to do that? Actually I have this approach: char = new four (); (* Var =: number = 0; i & lt; char.charlist.length; i ++) {if (char.charlist [i] .death) {char.charlist [i] = Four; Return; }} But the problem is that I have come from C ++ and I think calculation of index is completely useless. I'll do this, but it does not work in AS3, because I can not access this item from context: char = new letter (); / * ... * / for (var i: number = 0; i & lt; char.charlist.length; i ++) {var char_it: char = char.charlist [i]; If (char_it.death) {char_it = char; Return; Just a note: Charite is a stable member of class four. Do you have any ideas or a better attitude?

python - Retrieving a tuple from a collection of tuples based on a contained value -

I have a data structure that is a collection of tuples in this way: things = The first and the third elements are unique (123, 1, "Floll"), (154, 33, "Blurge"), (156, 55, "Blogger")) Code> to archive. What I have to do, it is to reference a third value and get a specific Tupal like this: & gt; & Gt; & Gt; To check each value, there should be a better method than writing a loop If things is a list, and you know that the third element is uni, what about the understanding of the list? & gt; & Gt; My_thing = [X in X for X] X [2] == "Blurgle"] [0] However under the hood, I agree that through all the values Goes and checks them individually. If you do not like it, then about changing the my_things structure is it a dict and using the first or third value as the key?

c++ - Callback unmanaged code from managed C# -

Bit of a history lesson here I am working on a legacy C ++ / MFC application and am trying to start an incremental modernization by pushing components written in C # (WinForms and later WPF). I have Net / 1.1 and VS / 2003 for many reasons which are impossible to solve in the near future. Currently, as a proof of concept, it works like something: #pragma push_macro ("new") #undef New WinFormA :: Form1 * Myform; Myform = __gc new WinFormA :: Form1 (); Myform-> ShowDialog (); #pragma pop_macro ("new") The problem I am having is - I need unmanaged C ++ / MFC code to pass the callback pointer in the Managed C # Winform code So that I can capture user interaction and process them through the application. I have seen some articles, but it does not work in VS / 2003 (the compiler does not like representative syntax). Is there any other option? I do not think I can use DLLImport because I do not need to interact with specific application examples, not f

bluetooth - GameKit in iPhone SDK 3.0 -

Do I need to use to search for partners in the new iPhone SDK 3.0 < / P> I really do not want to use it, but I want to use a peer-to-peer Bluetooth connection. Is there a sample code that shows the Bluetooth connection without using a peer picker? The game provided by Apple uses a peer picker, so I can not use it. Two ways to do this The first method uses the GameKit API Begin with two separate sections, which implement the G2CessionDelegate protocol and serve as a gamekit / Bluetooth "handler" and the second presentation acts as a UI ( Most likely any kind of visual controller with a table view). The way in which you will wire it, manages the handler gamekit notifications, etc. and then attempts to implement methods on the UI to update the table view after connecting with a colleague. In this way, to arrive and go to devices, your picker list - (BOOL) startPeer {BOOL result = no; If (! _session) {_session = [[GKSession alloc] initWithSessionID: B

Can Lua be used for application development? -

With the intermediate knowledge of VB6, people have recently suggested to "upgrade" a new language. I'm thinking of Lua - it's easy, simple and fast but it does not seem that, ,,, and. There is no information about how to create similar applications. Yes, it can. And it's easy to try on a small project. IMHO, it is ideally suited to create small applications with GUI when it comes to joining the ideal toolkit. Since you mentioned Visual Basic, I think that you are now focusing on Windows. In that case, check the package. Laa Lua language cores for Windows integrates with a large number of useful extension modules, and packages it with the appropriate Windows installer. Contains a version in which there is a syntax color for Leah and an integrated debugger. It also includes binding for both GUI toolkits I have used Lou with the IU to create several utilities, it is possible to create very detailed applications without the support of the collected code.
