  • Using Gems with MacRuby

    - by Craig Williams
    How do you use gems from a MacRuby .5 application on Snow Leopard? Do I need to specify the gem path? If so, how do I do this? Best scenario is to package the gems inside the application so the user would not have to install them when the app is distributed.

  • What's the correct way to use Cakephp urls?

    - by Pichan
    Hello all, it's my first post here :) I'm having some difficulties with dealing with urls and parameters. I've gone through the router class api documentation over and over again and found nothing useful. First of all, I'd like to know if there is any 'universal' format in CakePHP(1.3) for handling urls. I'm currently handling all my urls as simple arrays(in the format that Router::url and $html-link accepts) and it's easy as long as I only need to pass them as arguments to cake's own methods. It usually gets tricky if I need something else. Mainly I'm having problems with converting string urls to the basic array format. Let's say I want to convert $arrayUrl to string and than again into url: $arrayUrl=array('controller'=>'SomeController','action'=>'someAction','someValue'); $url=Router::url($arrayUrl); //$url is now '/path/to/site/someController/someAction/someValue' $url=Router::normalize($url); //remove '/path/to/site' $parsed=Router::parse($url); /*$parsed is now Array( [controller] => someController [action] => someAction [named] => Array() [pass] => Array([0] => someValue) [plugin] => ) */ That seems an awful lot of code to do something as simple as to convert between 2 core formats. Also, note that $parsed is still not in the same as $arrayUrl. Of course I could tweak $parsed manually and actually I've done that a few times as a quick patch but I'd like to get to the bottom of this. I also noticed that when using prefix routing, $this-params in controller has the prefix embedded in the action(i.e. [action] = 'admin_edit') and the result of Router::parse() does not. Both of course have the prefix in it's own key. To summarize, how do I convert an url between any of these 3(or 4, if you include the prefix thing) mentioned formats the right way? Of course it would be easy to hack my way through this, but I'd still like to believe that cake is being developed by a bunch of people who have a lot more experience and insight than me, so I'm guessing there's a good reason for this "perceived misbehavior". I've tried to present my problem as good as I can, but due to my rusty english skills, I had to take a few detours :) I'll explain more if needed.

  • Partials in Liquid

    - by kostia
    Hello, We're trying to rewrite our current views from ERb to Liquid and we got following problem: we have a lot of render(:partial => '/path/to/partial') in our code, but we found absolutely no instructions how to render partials in Liquid. The only one solution we found was with help of render_to_string but it's just to ugly to be true. Thanx!

  • Normalizing URI to make it work correctly with MakeRelativeUri

    - by dr. evil
    Dim x AS New URI("http://www.example.com/test//test.asp") Dim rel AS New URI("http://www.example.com/xxx/xxx.asp") Console.Writeline(x.MakeRelativeUri(rel).Tostring()) In here output is: ../../xxx/xxx.asp Which looks correct almost all web servers will process the two of the following as same request: http://www.example.com/test//test.asp http://www.example.com/test/test.asp What's the best way to fix this behaviour is there any API to do this, or shall manually create a new URI and remove all // in the path?

  • Compiling the ffmpeg on iPhone?

    - by user287225
    I downloaded the iFrameExtractor sample code and try to compile it with the iPhone simulator version 3.1.3 The project shows the following errors ( http://img514.imageshack.us/img514/3245/66948298.png ) even thought I added *.a libraries to my project. All libraries was under the library searching path. I guess it is a linking problem. Anyone can recommend to me a configuration for compiling ffmpeg on x86? Thanks in advance.

  • Is there any way to evaluate (expand-file-name) in .dir-locals.el?

    - by vava
    I'm trying to move all my compilation config (compilation-command and compilation-directory to be exact) to .dir-locals.el file at the top of my project. It is working fine except that I can't find the way to use expand-file-name there and without it I have to use absolute path, which is not really convenient. So, is there a way (or a dirty hack) to make local directory variables to evaluate values before assigning?

  • Dependency Property Set Priority: CodeBehind vs. XAML

    - by LukePet
    When I initialize a control property from code, the binding to the same property defined on XAML don't work. Why? For Example, I set control properties on startup with this statements: myControl.SetValue(UIElement.VisibilityProperty, DefaultProp.Visibility); myControl.SetValue(UIElement.IsEnabledProperty, DefaultProp.IsEnabled); and on xaml I bind the property of myControl in this way: IsEnabled="{Binding Path=IsKeyControlEnabled}" now, when the property "IsKeyControlEnabled" changes to false, myControl remains enabled (because it's initialize with true value). How can I do?

  • All embedded databases fail to open connections

    - by rsteckly
    Hi, I'm working on a winforms desktop application that needs to store data. I made the really bad decision to try and embed a database. I've tried: SQLite VistaDB SQL Server Compact In each case, I was able to generate a Entity Framework Model over the basic schema I've created. I have an event that adds data that I've been using to test these databases. Well, I kept adding a new record using EF and finding it didn't actually insert a record. In debugging, I checked the context object to see what was happening. It turns out that it is saying "the underlying provider failed to open," or something to that effect. It was not throwing an exception, just not inserting a record. The same thing has happened for all 3 embedded databases--prompting me to get it through my dense head that there has to be something wrong with my configuration. Well, I tried to write some basic sql using a sqlconnection and sqlcommand. This time it throws an exception. In the SQL Server Compact case, it now says: A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified) I thought perhaps a problem was the path in app.Config. So I changed the connection string to: Note that I simplified the path away from anything that might have spaces and avoided using the Data Directory nonsense that causes problem when the debugging directory does not match the preconfigured value for the data directory. I'm running Windows 7; I thought perhaps it might be an access issue--so I tried running VS 2010 in Administrator mode. No luck. I also installed Sql Server Compact SP2, thinking this might be a bug. No luck. Anyway, I'm ready to pull my hair out. I'm on a tight deadline for this thing and didn't expect to spend the day trying to figure out what is going on.

  • How to trim whitespace from bash variable?

    - by too much php
    I have a shell script with this code: var=`hg st -R "$path"` if [ -n "$var" ]; then echo $var fi But the conditional code always executes because hg st always prints at least one newline character. Is there a simple way to strip whitespace from $var (like trim() in php)? or Is there a standard way of dealing with this issue? I could use sed or awk, but I'd like to think there is a more elegant solution to this problem.

  • Avoiding Redundancies in XML documents

    - by MarceloRamires
    I was working with a certain XML where there were no redundancies <person> <eye> <eye_info> <eye_color> blue </eye_color> </eye_info> </eye> <hair> <hair_info> <hair_color> blue </hair_color> </hair_info> </hair> </person> As you can see, the sub-tag eye-color makes reference to eye in it's name, so there was no need to avoid redundancies, I could get the eye color in a single line after loading the XML into a dataset: dataset.ReadXml(path); value = dataset.Tables("eye_info").Rows(0)("eye_color"); I do realise it's not the smartest way of doing so, and this situation I'm having now wasn't unforeseen. Now, let's say I have to read xml's that are in this format: <person> <eye> <info> <color> blue </color> </info> </eye> <hair> <info> <color> blue </color> </info> </hair> </person> So If I try to call it like this: dataset.ReadXml(path); value = dataset.Tables("info").Rows(0)("color"); There will be a redundancy, because I could only go as far as one up level to identify a single field in a XML with my previous method, and the 'disambiguator' is three levels above. Is there a practical way to reach with no mistake a single field given all the above (or at least a few) fields ?
