How can I provide users with the functionality of the DBUnit DatabaseOperation methods from a web in

- by reckoner

I am currently updating a java-based web application which allows database developers to create stored procedure regression test suites for database testing. Currently, for test setup, execution and clean-up stages, the user is provided with text boxes where they are able to enter SQL code which is executed by the isql command. I would like to extend the application to use DB Unit’s DatabaseOperation methods to provide more ways to setup the state of the database than just SQL statements. The main reason for using Db Unit rather than just SQL statements is to be able to create and store xml and xls DataSets on a server where they can be associated with their test cases and used for data setup. My question is: How can I provide users with the functionality of the DBUnit DatabaseOperation methods from a web interface? I have considered: Creating a simple programming language and a parser to read some simple syntax involving the DB Unit method names which accept a parameter being the file location to an xml or xls DataSet. I was thinking of allowing the user to register the files they need with the web app which would catalogue them and provide each file with an identifier which could passed as a parameter to the methods in this simple programming language. Creating an XML DTD which provides the user with the ability to specify operations and parameters. If I went this approach, how can I execute the methods and their parameters that I parse from the XML document? Creating a table in the database which stores the method and a FK relation to a catalogued DataSet file, however I don’t think this would be good solution due to the fact that data entry would be tedious. Thanks for your help.

python packaging causes importerror

I am getting an annoying import error when I try to import a variable in an init.py file.

Specializing a class template constructor

- by SilverSun

I'm messing around with template specialization and I ran into a problem with trying to specialize the constructor based on what policy is used. Here is the code I am trying to get to work. #include <cstdlib> #include <ctime> class DiePolicies { public: class RollOnConstruction { }; class CallMethod { }; }; #include <boost/static_assert.hpp> #include <boost/type_traits/is_same.hpp> template<unsigned sides = 6, typename RollPolicy = DiePolicies::RollOnConstruction> class Die { // policy type check BOOST_STATIC_ASSERT(( boost::is_same<RollPolicy, DiePolicies::RollOnConstruction>::value || boost::is_same<RollPolicy, DiePolicies::CallMethod>::value )); unsigned m_die; unsigned random() { return rand() % sides; } public: Die(); void roll() { m_die = random(); } operator unsigned () { return m_die + 1; } }; template<unsigned sides> Die<sides, DiePolicies::RollOnConstruction>::Die() : m_die(random()) { } template<unsigned sides> Die<sides, DiePolicies::CallMethod>::Die() : m_die(0) { } ...\main.cpp(29): error C3860: template argument list following class template name must list parameters in the order used in template parameter list ...\main.cpp(29): error C2976: 'Die' : too few template arguments ...\main.cpp(31): error C3860: template argument list following class template name must list parameters in the order used in template parameter list Those are the errors I get in Microsoft Visual Studio 2010. I'm thinking either I can't figure out the right syntax for the specialization, or maybe it isn't possible to do it this way.

typename resolution in cases of ambiguity

- by parapura rajkumar

I was playing with Visual Studio and templates. Consider this code struct Foo { struct Bar { }; static const int Bar=42; }; template<typename T> void MyFunction() { typename T::Bar f; } int main() { MyFunction<Foo>(); return 0; } When I compile this is either Visual Studio 2008 and 11, I get the following error error C2146: syntax error : missing ';' before identifier 'f' Is Visual Studio correct in this regard ? Is the code violating any standards ? If I change the code to struct Foo { struct Bar { }; static const int Bar=42; }; void SecondFunction( const int& ) { } template<typename T> void MyFunction() { SecondFunction( T::Bar ); } int main() { MyFunction<Foo>(); return 0; } it compiles without any warnings. In Foo::BLAH a member preferred over a type in case of conflicts ?

x86_64 assembler: only one call per subroutine?

- by zneak

Hello everyone, I decided yesterday to start doing assembler. Most of it is okay (well, as okay as assembler can be), but I'm getting some problems with gas. It seems that I can call functions only once. After that, any subsequent call opcode with the same function name will fail. I must be doing something terribly wrong, though I can't see what. Take this small C function for instance: void path_free(path_t path) { if (path == NULL) return; free(((point_list_t*)path)->points); free(path); } I "translated" it to assembler like that: .globl _path_free _path_free: push rbp mov rbp, rsp cmp rdi, 0 jz byebye push rdi mov rdi, qword ptr [rdi] call _free pop rdi sub rsp, 8 call _free byebye: leave ret This triggers the following error for the second call _free: suffix or operands invalid for ``call''. And if I change it to something else, like free2, everything works (until link time, that is). Assembler code gcc -S gave me looks very similar to what I've done (except it's in AT&T syntax), so I'm kind of lost. I'm doing this on Mac OS X under the x86_64 architecture.

Why do compiled Haskell libraries see invalid static FFI storage?

- by John Millikin

I am using GHC 6.12.1, in Ubuntu 10.04 When I try to use the FFI syntax for static storage, only modules running in interpreted mode (ie GHCI) work properly. Compiled modules have invalid pointers, and do not work. I'd like to know whether anybody can reproduce the problem, whether this an error in my code or GHC, and (if the latter) whether it's a known issue. Given the following three modules: -- A.hs {-# LANGUAGE ForeignFunctionInterface #-} module A where import Foreign import Foreign.C foreign import ccall "&sys_siglist" siglist_a :: Ptr CString -- -- B.hs {-# LANGUAGE ForeignFunctionInterface #-} module B where import Foreign import Foreign.C foreign import ccall "&sys_siglist" siglist_b :: Ptr CString -- -- Main.hs {-# LANGUAGE ForeignFunctionInterface #-} module Main where import Foreign import Foreign.C import A import B foreign import ccall "&sys_siglist" siglist_main :: Ptr CString main = do putStrLn $ "siglist_a = " ++ show siglist_a putStrLn $ "siglist_b = " ++ show siglist_b putStrLn $ "siglist_main = " ++ show siglist_main peekSiglist "a " siglist_a peekSiglist "b " siglist_b peekSiglist "main" siglist_main peekSiglist name siglist = do ptr <- peekElemOff siglist 2 str <- maybePeek peekCString ptr putStrLn $ "siglist_" ++ name ++ "[2] = " ++ show str I would expect something like this output, where all pointer values identical and valid: $ runhaskell Main.hs siglist_a = 0x00007f53a948fe00 siglist_b = 0x00007f53a948fe00 siglist_main = 0x00007f53a948fe00 siglist_a [2] = Just "Interrupt" siglist_b [2] = Just "Interrupt" siglist_main[2] = Just "Interrupt" However, if I compile A.hs (with ghc -c A.hs), then the output changes to: $ runhaskell Main.hs siglist_a = 0x0000000040378918 siglist_b = 0x00007fe7c029ce00 siglist_main = 0x00007fe7c029ce00 siglist_a [2] = Nothing siglist_b [2] = Just "Interrupt" siglist_main[2] = Just "Interrupt"

Implementing eval and load functions inside a scripting engine with Flex and Bison.

- by Simone Margaritelli

Hy guys, i'm developing a scripting engine with flex and bison and now i'm implementing the eval and load functions for this language. Just to give you an example, the syntax is like : import std.*; load( "some_script.hy" ); eval( "foo = 123;" ); println( foo ); So, in my lexer i've implemented the function : void hyb_parse_string( const char *str ){ extern int yyparse(void); YY_BUFFER_STATE prev, next; /* * Save current buffer. */ prev = YY_CURRENT_BUFFER; /* * yy_scan_string will call yy_switch_to_buffer. */ next = yy_scan_string( str ); /* * Do actual parsing (yyparse calls yylex). */ yyparse(); /* * Restore previous buffer. */ yy_switch_to_buffer(prev); } But it does not seem to work. Well, it does but when the string (loaded from a file or directly evaluated) is finished, i get a sigsegv : Program received signal SIGSEGV, Segmentation fault. 0xb7f2b801 in yylex () at src/lexer.cpp:1658 1658 if ( YY_CURRENT_BUFFER_LVALUE->yy_buffer_status == YY_BUFFER_NEW ) As you may notice, the sigsegv is generated by the flex/bison code, not mine ... any hints, or at least any example on how to implement those kind of functions? PS: I've succesfully implemented the include directive, but i need eval and load to work not at parsing time but execution time (kind of PHP's include/require directives).

mod_rewrite with location-based ACL in apache?

- by Alexey

Hi. There is a CGI-script that provides some API for our customers. Call syntax is: script.cgi?module=<str>&func=<str>[&other-options] The task is to make different authentiction rules for different modules. Optionally, it will be great to have nice URLs. My config: <VirtualHost *:80> DocumentRoot /var/www/example ServerName example.com # Global policy is to deny all <Location /> Order deny,allow Deny from all </Location> # doesn't work :( <Location /api/foo> Order deny,allow Deny from all Allow from 127.0.0.1 </Location> RewriteEngine On # The only allowed type of requests: RewriteRule /api/(.+?)/(.+) /cgi-bin/api.cgi?module=$1&func=$2 [PT] # All others are forbidden: RewriteRule /(.*) - [F] RewriteLog /var/log/apache2/rewrite.log RewriteLogLevel 5 ScriptAlias /cgi-bin /var/www/example <Directory /var/www/example> Options -Indexes AddHandler cgi-script .cgi </Directory> </VirtualHost> Well, I know that problem is order of processing that directives. <Location>s will be processed after mod_rewrite has done its work. But I believe there is a way to change it. :) Using of standard Order deny,allow + Allow from <something> directives is preferable because it's commonly used in other places like this. Thank you for your attention. :)

Zend framework controller action helper

I am getting fatal error after adding the action helper class. I am trying to load layout corresponding to called layout. Following is my code snippet: First of all i added a helper class under application/controller/helpers: class Zend_Controller_Action_Helper_Layout extends Zend_Controller_Action_Helper_Abstract { public $pluginLoader; public function __construct() { // TODO Auto-generated Constructor $this->pluginLoader = new Zend_Loader_PluginLoader (); } public function preDispatch() { $bootstrap = $this->getActionController()->getInvokeArg('bootstrap'); $config = $bootstrap->getOptions(); $module = $this->getRequest()->getModuleName(); if (isset($config[$module]['resources']['layout']['layout'])) { $layoutScript = $config[$module]['resources']['layout']['layout']; $this->getActionController()->getHelper('layout')->setLayout($layoutScript); } } } Then i added a loader in bootstrap.php: protected function _initLayoutHelper() { $this->bootstrap('frontController'); Zend_Controller_Action_HelperBroker::addPath(APPLICATION_PATH .'/controllers/helpers'); $layout = Zend_Controller_Action_HelperBroker::addHelper(new Zend_Controller_Action_Helper_Layout()); } Following is my application.ini: [production] autoloaderNamespaces.tree = "Tree_" phpSettings.display_startup_errors = 0 phpSettings.display_errors = 0 includePaths.library = APPLICATION_PATH "/../library" bootstrap.path = APPLICATION_PATH "/Bootstrap.php" bootstrap.class = "Bootstrap" resources.frontController.controllerDirectory = APPLICATION_PATH "/controllers" resources.frontController.moduleDirectory = APPLICATION_PATH "/modules" resources.frontController.helperDirectory = APPLICATION_PATH "/controllers/helpers" resources.modules[] = "" contact.resources.frontController.defaultControllerName = "index" resources.layout.layoutPath = APPLICATION_PATH "/layouts/scripts" resources.layout.layout = layout admin.resources.layout.layout = admin admin.resources.layout.layoutPath = APPLICATION_PATH "/layouts/scripts" resources.view[] = [staging : production] [testing : production] phpSettings.display_startup_errors = 1 phpSettings.display_errors = 1 [development : production] phpSettings.display_startup_errors = 1 phpSettings.display_errors = 1 While running this code i am getting following errors: Warning: include(Zend\Controller\Action\Helper\LayoutLoader.php) [function.include]: failed to open stream: No such file or directory in D:\personal\proj\renovate\library\Zend\Loader.php on line 83 Warning: include() [function.include]: Failed opening 'Zend\Controller\Action\Helper\LayoutLoader.php' for inclusion (include_path='D:\personal\proj\renovate\application/../library;D:\personal\proj\renovate\library;.;C:\php5\pear') in D:\personal\proj\renovate\library\Zend\Loader.php on line 83 Fatal error: Class 'Zend_Controller_Action_Helper_LayoutLoader' not found in D:\personal\proj\renovate\application\Bootstrap.php on line 33 Kindly let me know, how can i come out from this issue.

What is a good way to assign order #s to ordered rows in a table in Sybase

- by DVK

I have a table T (structure below) which initially contains all-NULL values in an integer order column: col1 varchar(30), col2 varchar(30), order int NULL I also have a way to order the "colN" columns, e.g. SELECT * FROM T ORDER BY some_expression_involving_col1_and_col2 What's the best way to assign - IN SQL - numeric order values 1-N to the order table, so that the order values match the order of rows returned by the above ORDER BY? In other words, I would like a single query (Sybase SQL syntax so no Oracle's rowcount) which assigns order values so that SELECT * FROM T ORDER BY order returns 100% same order of rows as the query above. The query does NOT necessarily need to update the table T in place, I'm OK with creating a copy of the table T2 if that'll make the query simpler. NOTE1: A solution must be real query or a set of queries, not involving a loop or a cursor. NOTE2: Assume that the data is uniquely orderable according to the order by above - no need to worry about situation when 2 rows can be assigned the same order at random. NOTE3: I would prefer a generic solution, but if you wish a specific example of ordering expression, let's say: SELECT * FROM T ORDER BY CASE WHEN col1="" THEN "AAAAAA" ELSE col1 END, ISNULL(col2, "ZZZ")

how to apply iddata into calculation?

- by Sam

I am trying to figure out how to combine the input and output data into the ARX model and then apply it into the BIC (Bayesian Information Criterion) formula. Below is the code that I am currently working on: for i=1:30; %% Set Model Order data=iddata(output,input,1); model = arx(data,[8 9 i]); yp = predict(model,data); ye = regress(data,yp{1,1}(1:4018,1)); M(i) = var(yp); BIC(i)=(N+i*(log(N)-1))/(N-i)*log(M(i)); end But it does not work. It keep on giving me an error something like below: "The syntax "Data{...}" is not supported. Use the "getexp" command to extract individual experiments from an IDDATA object." I did not understand what does that mean. Can someone explain it to me and where do I do wrong on my piece of code? Thanks in advance. Sam.

Verify an event was raised by mocked object

- by joblot

In my unit test how can I verify that an event is raised by the mocked object. I have a View(UI) -- ViewModel -- DataProvider -- ServiceProxy. ServiceProxy makes async call to serivce operation. When async operation is complete a method on DataProvider is called (callback method is passed as a method parameter). The callback method then raise and event which ViewModel is listening to. For ViewModel test I mock DataProvider and verify that handler exists for event raised by DataProvider. When testing DataProvider I mock ServiceProxy, but how can I test that callback method is called and event is raised. I am using RhinoMock 3.5 and AAA syntax Thanks -- DataProvider -- public partial class DataProvider { public event EventHandler<EntityEventArgs<ProductDefinition>> GetProductDefinitionCompleted; public void GetProductDefinition() { var service = IoC.Resolve<IServiceProxy>(); service.GetProductDefinitionAsync(GetProductDefinitionAsyncCallback); } private void GetProductDefinitionAsyncCallback(ProductDefinition productDefinition, ServiceError error) { OnGetProductDefinitionCompleted(this, new EntityEventArgs<ProductDefinition>(productDefinition, error)); } protected void OnGetProductDefinitionCompleted(object sender, EntityEventArgs<ProductDefinition> e) { if (GetProductDefinitionCompleted != null) GetProductDefinitionCompleted(sender, e); } } -- ServiceProxy -- public class ServiceProxy : ClientBase<IService>, IServiceProxy { public void GetProductDefinitionAsync(Action<ProductDefinition, ServiceError> callback) { Channel.BeginGetProductDefinition(EndGetProductDefinition, callback); } private void EndGetProductDefinition(IAsyncResult result) { Action<ProductDefinition, ServiceError> callback = result.AsyncState as Action<ProductDefinition, ServiceError>; ServiceError error; ProductDefinition results = Channel.EndGetProductDefinition(out error, result); if (callback != null) callback(results, error); } }

jQuery attribute question

- by Nick Simone

I'm trying to select a series of divs one at a time. I'm sure theres a better way to do this, but I gave them all unique rels and I'm using the rels to select them one at a time. I want to move them over the width of the div, then animate it dropping down the screen. What I have is: $(document).ready(function(){ var totalbricks = 7; var index = 2; $(".brick").animate({top:"600px"}); while(index < totalbricks) { var postion = 45*index; $(".brick[rel='+index+']").css('left', postion+'px'); $(".brick[rel='+index+']").animate({top:"600px"}); index++; } }); All the divs are in a container div. Jquery docs say, 'Variables can be used using the following syntax: [name='" +MyVar+ "']' What am I doing wrong? Here is the HTML that is being used by the jQuery <body> <div id="container"> <div id="canvas"> <div class="brick" rel="1"> </div> <div class="brick" rel="2"> </div> <div class="brick" rel="3"> </div> <div class="brick" rel="4"> </div> <div class="brick" rel="5"> </div> <div class="brick" rel="6"> </div> <div class="brick" rel="7"> </div> </div> </div> </body>

Poco library for c++, declare namespace for custom element

- by Mikhail

I want to create an XML document by building a DOM document from scratch, with syntax like: AutoPtr<Document> doc = new Document; AutoPtr<Element> root = doc->createElement("root"); doc->appendChild(root); AutoPtr<Element> element1 = doc->createElementNS("http://ns1", "ns1:element1"); root->appendChild(element1); AutoPtr<Element> element2 = doc->createElementNS("http://ns1", "ns1:element2"); root->appendChild(element2); DOMWriter writer; writer.setNewLine("\n"); writer.setOptions(XMLWriter::PRETTY_PRINT); writer.writeNode(std::cout, doc); But, when I write it, I get next result: <root> <ns1:element1 xmlns:ns1="http://ns1"/> <ns1:element2 xmlns:ns1="http://ns1"/> </root> So namespace ns1 declared two times, and I want to declare it inside "root" element. Is there way to get next representation: <root xmlns:ns1="http://ns1"/> <ns1:element1/> <ns1:element2/> </root>

Form (or Formset?) to handle multiple table rows in Django

- by Ben

Hi, I'm working on my first Django application. In short, what it needs to do is to display a list of film titles, and allow users to give a rating (out of 10) to each film. I've been able to use the {{ form }} and {{ formset }} syntax in a template to produce a form which lets you rate one film at a time, which corresponds to one row in a MySQL table, but how do I produce a form that iterates over all the movie titles in the database and produces a form that lets you rate lots of them at once? At first, I thought this was what formsets were for, but I can't see any way to automatically iterate over the contents of a database table to produce items to go in the form, if you see what I mean. Currently, my views.py has this code: def survey(request): ScoreFormSet = formset_factory(ScoreForm) if request.method == 'POST': formset = ScoreFormSet(request.POST, request.FILES) if formset.is_valid(): return HttpResponseRedirect('/') else: formset = ScoreFormSet() return render_to_response('cf/survey.html', { 'formset':formset, }) And my survey.html has this: <form action="/survey/" method="POST"> <table> {{ formset }} </table> <input type = "submit" value = "Submit"> </form> Oh, and the definition of ScoreForm and Score from models.py are: class Score(models.Model): movie = models.ForeignKey(Movie) score = models.IntegerField() user = models.ForeignKey(User) class ScoreForm(ModelForm): class Meta: model = Score So, in case the above is not clear, what I'm aiming to produce is a form which has one row per movie, and each row shows a title, and has a box to allow the user to enter their score. If anyone can point me at the right sort of approach to this, I'd be most grateful. Thanks, Ben

Unexpected $end in PHP file

- by mattbd

I'm working on a PHP contact form, but I can't get it to work. I get the following error in the Apache server log, running on an Ubuntu Server VM: PHP Parse error: syntax error, unexpected $end in /home/matthew/Sites/contactFormResponse.php on line 75, referer: http://192.168.1.4/contactForm.php From googling this error, it sounds like it's normally caused by either using the short PHP tag when the server's not set up to recognise them, or by having a block of code that isn't closed correctly. But as far as I can see that isn't the case here - as far as I can see it's all closed correctly. Here's the PHP code: <?php error_reporting(E_ALL); // Define variables to hold the name, email address and message, and import the information into the variables $name = $_POST['NameInput']; $email = $_POST['EmailAddress']; $telno = $_POST['ContactNumber']; $querytype = $_POST['QueryType']; $bookingstartdate = $_POST['BookingStartDay'] . $_POST['BookingStartMonth'] . $_POST['BookingStartYear']; $bookingenddate = $_POST['BookingEndDay'] . $_POST['BookingEndMonth'] . $_POST['BookingEndYear']; $message = $_POST['QueryText']; // Validate the inputs - send it if it's OK if(3 < strlen($name) && 3 < strlen($email)) { $email_message = <<< EMAIL Message from contact form at holidaychalet.co.uk Name: $name Email: $email Contact Number: $telno Query Type: $querytype Booking Start Date: $bookingstartdate Booking End Date: $bookingenddate The message: $message EMAIL; $headers = "cc:[email protected]\r\n"; if(mail('matthew@localhost','Contact form email', $email_message, $headers)) { echo "Thanks for completing the form! I'll be in touch shortly!"; } else { echo "Something went wrong - please use the back button and try again"; } } else { echo "You didn't complete the form fully enough!

CLI include paths to run zend framework via cron

- by summerg

I wrote a command line utility using Zend Framework to do some nightly reporting. It uses a ton of the same functionality the accompanying site. It works great when I run it by hand, but when I run it on cron I have include path issues. Seems like it should be easily fixed with set_include_path, but maybe I'm missing something? My directory structure looks like this: /var/www/clientname/ application Globals.php commandline commandline_bootstrap.php public_html public_bootstrap.php library Zend In public_bootstrap.php I use set_include_path without a problem, relative to the current directory: set_include_path('../library' . PATH_SEPARATOR . get_include_path()); If I understand correctly, in commandline_bootstrap.php I need to put in the absolute path, so cron knows where everything is. My file starts like this: error_reporting(E_ALL); set_include_path('/var/www/clientname/library' . PATH_SEPARATOR . get_include_path()); require_once "../application/Globals.php"; But when I run it via cron I get the following error: PHP Fatal error: require_once(): Failed opening required '../application/Globals.php' (include_path='/var/www/clientname/library/') in /var/www/clientname/commandline/zfcli.php on line 11 I think PHP is accepting my new path, because when I run it command line and dump the phpinfo I can see: include_path = /var/www/clientname/library/:.:/usr/share/pear:/usr/share/php = .:/usr/share/pear:/usr/share/php I admit the syntax here looks a little strange, but I can’t figure out how to fix it. Any suggestions would be greatly appreciated. Thanks summer

Is XMLReader a SAX parser, a DOM parser, or neither?

- by Renesis

I am testing various methods to read (possibly large, and very often) XML configuration files in PHP. No writing is ever needed. I have two successful implementations, one using SimpleXML (which I know is a DOM parser) and one using XMLReader. I know that a DOM reader must read the whole tree and therefore uses more memory. My tests reflect that. I also know that A SAX parser is an "event-based" parser that uses less memory because it reads each node from the stream without checking what is next. XMLReader also reads from a stream with the cursor providing data about the node it is currently at. So, it definitely sounds like XMLReader (http://us2.php.net/xmlreader) is not a DOM parser, but my question is, is it a SAX parser, or something else? It seems like XMLReader behaves the way a SAX parser does but does not throw the events themselves (in other words, can you construct a SAX parser with XMLReader?) If it is something else, does the classification it's in have a name?

Fluently setting C# properties and chaining methods

- by John Feminella

I'm using .NET 3.5. We have some complex third-party classes which are automatically generated and out of my control, but which we must work with for testing purposes. I see my team doing a lot of deeply-nested property getting/setting in our test code, and it's getting pretty cumbersome. To remedy the problem, I'd like to make a fluent interface for setting properties on the various objects in the hierarchical tree. There are a large number of properties and classes in this third-party library, and it would be too tedious to map everything manually. My initial thought was to just use object initializers. Red, Blue, and Green are properties, and Mix() is a method that sets a fourth property Color to the closest RGB-safe color with that mixed color. Paints must be homogenized with Stir() before they can be used. Bucket b = new Bucket() { Paint = new Paint() { Red = 0.4; Blue = 0.2; Green = 0.1; } }; That works to initialize the Paint, but I need to chain Mix() and other methods to it. Next attempt: Create<Bucket>(Create<Paint>() .SetRed(0.4) .SetBlue(0.2) .SetGreen(0.1) .Mix().Stir() ) But that doesn't scale well, because I'd have to define a method for each property I want to set, and there are hundreds of different properties in all the classes. Also, C# doesn't have a way to dynamically define methods prior to C# 4, so I don't think I can hook into things to do this automatically in some way. Third attempt: Create<Bucket>(Create<Paint>().Set(p => { p.Red = 0.4; p.Blue = 0.2; p.Green = 0.1; }).Mix().Stir() ) That doesn't look too bad, and seems like it'd be feasible. Is this an advisable approach? Is it possible to write a Set method that works this way? Or should I be pursuing an alternate strategy?

Agile language for 2d game prototypes?

- by instanceofTom

Occasionally ( read: when my fiancé allows ) I like to prototype different game or game-like ideas I have. Usually I use Java or C# (not xna yet) because they are the languages I have the most practice with. However I would like to learn something more suited to agile development; a language in which it would be easier to knock out quick prototypes. At my job I have recently been working with looser (weak/dynamically typed) languages, specifically python and groovy, and I think something similar would fit what I am looking for. So, my question is: What languages (and framework/engine) would be good for rapidly developing prototypes of 2d game concepts? A few notes: I don't need blazing fast bitcrunching performance. In this case I would strongly prefer ease of development over performance. I'd like to use a language with a healthy community, which to me means a fair amount of maintained 3rd party, libraries. I'd like the language to be cross-platform friendly, I work on a variety of different operating systems and would like something that is portable with minimum effort. I can't imagine myself using a language with out decent options for debugging and editor syntax highlighting support. Note: If you are aware of a Java or C# library/framework that you think streamlines producing game prototypes I open to learning something new for those languages too

I am totally unable to add a fileTree (JQuery fileTree addon) to my asp.net page

- by Gadgetsan

okay, so i have an asp.net (C#) application and i want to add a list of file and folders on the page, so i figured i should use JQuery fileTree (http://abeautifulsite.net/2008/03/jquery-file-tree/#download) but now i am totally unable to display the file list. I initialise the page this way: Site.Master: <link rel="stylesheet" type="text/css" href="../../Content/superfish.css" media="screen"> <link href="../../Content/jqueryFileTree.css" rel="stylesheet" type="text/css" /> <script src="../../Scripts/jquery-1.4.1.min.js" type="text/javascript"></script> <script src="../../Scripts/jquery.easing.1.3.js" type="text/javascript"></script> <script src="../../Scripts/jqueryFileTree.js" type="text/javascript"></script> <script src="../../Scripts/JqueryUI/js/jquery-ui-1.8.1.custom.min.js" type="text/javascript"></script> <script type="text/javascript" src="../../Scripts/jquery.dataTables.js"></script> <script type="text/javascript" src="../../Scripts/superfish.js"></script> <script type="text/javascript"> $(document).ready(function() { test = $('#fileTree').fileTree({script: "jqueryFileTree.aspx" }, function(file) { openFile(file); }); $("button").button(); oTable = $('#data').dataTable({ "bJQueryUI": true, "sPaginationType": "full_numbers", "bSort": true }); }); </script> and in the page, i put my div this way: <asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server"> Documents but i'm positive that jqueryFileTree.aspx is never "called" because if i return this page in my controller, it shows the list of files/folder correctly, so it's also not a problem with my aspx connector... Also i checked, on the JS console, it gives no error and there is nothing more in the page source code i've been trying to solve this all day without success so your help is apreciated

PHP: retrieve all declared namespaces of a DOMElement

- by soulmerge

I am using the DOM extension to parse an xml file containing xml namespaces. I would have that namespace declarations are treated just like any other attribute, but my tests seem to disagree. I have a document that starts like this: <rdf:RDF xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#" xmlns="http://purl.org/rss/1.0/" xmlns:taxo="http://purl.org/rss/1.0/modules/taxonomy/" xmlns:dc="http://purl.org/dc/elements/1.1/" xmlns:syn="http://purl.org/rss/1.0/modules/syndication/" xmlns:prism="http://purl.org/rss/1.0/modules/prism/" xmlns:admin="http://webns.net/mvcb/" > And a test code like this: $doc = new DOMDocument(); $doc->loadXml(file_get_contents('/home/soulmerge/tmp/rss1.0/recent.xml')); $root = $doc->documentElement; var_dump($root->tagName); # prints 'string(7) "rdf:RDF"' var_dump($root->attributes->item(0)); # prints 'NULL' var_dump($root->getAttributeNode('xmlns')); # prints 'object(DOMNameSpaceNode)#3 (0) {}' So the questions are: Does anyone know where could I find the documentation of DOMNameSpaceNode? A search on php.net does not yield any useful result. How do I extract all those namespace declarations from that DOMElement?

Project management: Implementing custom errors in VS compilation process

- by David Lively

Like many architects, I've developed coding standards through years of experience to which I expect my developers to adhere. This is especially a problem with the crowd that believes that three or four years of experience makes you a senior-level developer.Approaching this as a training and code review issue has generated limited success. So, I was thinking that it would be great to be able to add custom compile-time errors to the build process to more strictly enforce this and other guidelines. For instance, we use stored procedures for ALL database access, which provides procedure-level security, db encapsulation (table structure is hidden from the app), and other benefits. (Note: I am not interested in starting a debate about this.) Some developers prefer inline SQL or parametrized queries, and that's fine - on their own time and own projects. I'd like a way to add a compilation check that finds, say, anything that looks like string sql = "insert into some_table (col1,col2) values (@col1, @col2);" and generates an error or, in certain circumstances, a warning, with a message like Inline SQL and parametrized queries are not permitted. Or, if they use the var keyword var x = new MyClass(); Variable definitions must be explicitly typed. Do Visual Studio and MSBuild provide a way to add this functionality? I'm thinking that I could use a regular expression to find unacceptable code and generate the correct error, but I'm not sure what, from a performance standpoint, is the best way to to integrate this into the build process. We could add a pre- or post-build step to run a custom EXE, but how can I return line- and file-specifc errors? Also, I'd like this to run after compilation of each file, rather than post-link. Is a regex the best way to perform this type of pattern matching, or should I go crazy and run the code through a C# parser, which would allow node-level validation via the parse tree? I'd appreciate suggestions and tales of prior experience.

How can I diff against a revision of a single file using only the default Git GUI tools?

- by Rich

I want to view the history of a single file, and then compare a single revision from that history against the current version. On the command line, this is easy: Run: git log -- <filename> Locate the version you want to compare, Run: git diff <commitid> -- <filename> But how can this be done using only the default Git gui tools, git gui and gitk? I know of two methods using gitk, but they're both horribly clunky: Either: Select the New View option from the View menu, Type in the full path to your file into the box labelled Enter files and directories to include, one per line, Locate the version you want to compare by looking at the highlighted items in the top pane, and click on it to select it, Right-click on the current version and select Diff selected - this, Or: Select Tree in the bottom right-hand pane, Locate the file you want to look at, right-click on it, and select Highlight this only, Locate the version you want to compare by looking at the highlighted items in the top pane, and click on it to select it, Right-click on the current version and select Diff selected - this, Click on the file in the bottom right-hand pane to jump to it in the diff output, or scroll manually. Is a better method than this?

JFLAP Turing Machine shortcut problem

- by Robert Lamb

In JFLAP (http://jflap.org), there are some shortcuts for Turing machine transitions. One of these shortcuts allows you to transition as long as the current tape symbol isn't the indicated symbol. For example, the transition !g,x;R basically says "Take this transition if the current tape symbol is not g". So far, so good. But the transition I want is !?,~;R which basically says "Move right as long as the current symbol is not the end-of-string (empty cell) symbol". The problem is I cannot figure out how to type in "!?". The JFLAP online documentation (http://www.jflap.org/tutorial/turing/one/index.html#syntax) has this to say: The first shortcut is that there exists the option of using the “!” character to convey the meaning of “any character but this character.” For example, concerning the transition (!a; x, R), if the head encounters any character but an “a”, it will replace the character with an “x” and move right. To write the expression “!?”, just type a “1” in when inputting a command. My question is...how do I actually do what that last sentence is trying to explain to me? Thanks for your help! Robert
