preprocessor

Is there a HTML preprocessor that can do simple page processing similar to Server Side Includes , but produce a static set of HTML pages? I think they are called pre-processors. http://htmlhelp.com/links/preprocessors.html It's a HTML Pre-processor. More here : htmlpp 来源： https://stackoverflow.com/questions/5462610/html-preprocessor

I'm trying to have 2 version of my iPhone application within the same XCode project. The codebase it's almost the same and where I need to have different behaviours I've decided to use preprocessor's conditionals and the ${TARGET_NAME} tag. I've set the OTHER_CFLAGS to contain " -DTARGET_NAME=${TARGET_NAME} ". Then in my code I tried to do #if TARGET_NAME == myApp NSLog(@"pro"); #elif TARGET_NAME == myAppLite NSLog(@"lite"); #endif Unfortunately I always get "lite" printed out since TARGET_NAME == myApp it's always true: since TARGET_NAME is defined. I cannot for the life of me figure out how

I have a configuration that I'd like to dynamically control a preprocessor defined value through an environment variable. Is this possible? if it is how do I set in the preprocessor define table that I want to set the value based on the environment variable? In the "Build Settings" of a target of your project, you can add something like that to the "Preprocessor Macros" field: DEV_USERNAME="${USER}" Of course, the USER variable can be replaced by any environment variable available to Xcode build system. To get a list of those, you can add a run script to your target and enable the checkmark

Why doesn't #IF Not DEBUG work the way I'd expect in VB.NET? #If DEBUG Then Console.WriteLine("Debug") #End If #If Not DEBUG Then Console.WriteLine("Not Debug") #End If #If DEBUG = False Then Console.WriteLine("Not Debug") #End If ' Outputs: Debug, Not Debug But, a manually set const does: #Const D = True #If D Then Console.WriteLine("D") #End If #If Not D Then Console.WriteLine("Not D") #End If ' Outputs: D And, of course, C# has the expected behavior as well: #if DEBUG Console.WriteLine("Debug"); #endif #if !DEBUG Console.WriteLine("Not Debug"); #endif // Outputs: Debug Turns out, it's not

I just started learning machine learning, when practicing one of the task, I am getting value error, but I followed the same steps as the instructor does. I am getting value error, please help. dff Country Name 0 AUS Sri 1 USA Vignesh 2 IND Pechi 3 USA Raj First I performed labelencoding, X=dff.values label_encoder=LabelEncoder() X[:,0]=label_encoder.fit_transform(X[:,0]) out: X array([[0, 'Sri'], [2, 'Vignesh'], [1, 'Pechi'], [2, 'Raj']], dtype=object) then performed One hot encoding for the same X onehotencoder=OneHotEncoder( categorical_features=[0]) X=onehotencoder.fit_transform(X).toarray

I just using Wix 3.5 with Visual Studio 2010, Windows 7. I unable to make a custom Preprocessor Extension run. I create the extension project in .NET 3.5. and copy the compiled dll into Wix 3.5 program files , plus set the Reference Path in the extension project properties but the Wix project build still failed with " undefined preprocessor function " on my extension. Example: Extension project: WixFileVersionExtension (from wixfileversionext.codeplex.com) Wix program files: "C:\Program Files\Windows Installer XML v3.5\bin" Am I missing something? Google can't answer me. Update: This is a bug

I've been a Java and VB.Net programmer for about 4 years and a C# programmer for about 6 months. I've also used a bunch of dynamic languages like Perl, Python, PHP, and JavaScript. I've never had a need for a preprocessor. My question is: why do you see such extensive use of preprocessors in C, C++, and Objective-C but rarely (or never) see it in languages like Java, C#, or Scala? Dima I don't know Objective-C, so my answer will be about contrasting the use of the preprocessor in C and C++. The preprocessor was originally necessary for C for several reasons. If I remember correctly, originally
