I'm hosting my blog in SquareSpace, and I need to add a <Script> tag at the footer of every post. In the middle of this <Script> tag, I need to replace a value with the permalink for the current post.

Does anyone know why this will not compile? I've tried both VS 2008 and GCC 4.something and both spit out errors. It doesn't matter whether or not I'm referencing "ThisFunctionDoesNotCompile()". I can workaround this by just passing 'InternalType' as a second template parameter to Base, but I'm still curious why this comes up as an er...

I'm trying to port a int a[][] from Java to C++. I'm using this class as a container ArrayRef for ints because it handles references, and the project uses it extensively. In the AbstractReader class I declared const ArrayRef<int> START_END_PATTERN_; const ArrayRef<int> MIDDLE_PATTERN_; const ArrayRef<ArrayRef<int> > L_PATTERNS_; co...
I upgraded a working Django app to 1.1 and I now get a KeyError exception on a for loop! Template error In template /vol/.../templates/base_bbn.html, error at line 7 Caught an exception while rendering: 'django.contrib.comments.urls.' You would think that there couldn't be a KeyError on a for loop like this because there would be a ...

I have already built the template, put it into my ItemTemplates directory beneath my documents folder, and it works, in the sense that I can add new items to the project through the template. However, ...
Hi all; My C++ is a little rusty having worked in Java and C# for the last half dozen years. I've got a stupid little error that I just cannot figure out. I've pared the code down as much as possible. #include <list> template<class T> class Subscriber { virtual void published( T t ) = 0; }; template <class T> class PubSub { priva...

Hi, Currently, I have some code as follows template<typename Type> Type* getValue(std::string name, bool tryUseGetter = true) { if(tryUseGetter) { if(_properties[name]->hasGetter) { return (Type*)_properties[name]->getter(); } return (Type*)_properties[name]->data; } else { return (Type*)_properties[name]->data; } } ...
I want to do something like template <typename T> void foo(const T& t) { IF bar(t) would compile bar(t); ELSE baz(t); } I thought that something using enable_if would do the job here, splitting up foo into two pieces, but I can't seem to work out the details. What's the simplest way of achieving this? ...
I've already implemented, using macros, a C++ property system that satisfied the following requirements: Property can be referenced using a integeral key Property can be accessed via a generic Set/Get Properties (and property keys) must be inheritable Properties can be registered with getters/setters and is implemented as follows E...
Hi, I am overloading operator << to implement a stream like interface for a class: template<typename T> CAudit& operator << ( const T& data ) { audittext << data; return *this; } CAudit& operator << ( LPCSTR data ) { audittext << data; return *this; } The template version fails to compile with "fatal error C1001: INT...
Hi. I would like to get your input on what would be the most fitting view layer for EJB 3.0 [1] Java application for me. JSF is no good because it is a mess when it comes to web URIs. I would like a view framework which would help with automating html form submission and validation while using clean URIs like example.com/story/1 or exam...

So I know there is a few templating engines out there, but I thought I'd ask for someones experience and reccomendation on one that can do what I'm after. I'd previously made an (intranet) web app that used asp.net editable listviews to take input and used an update panel to make it persist the data regularly (save) This worked ok but...
Sometimes it necessary to compary a string's length with a constant. For example: if ( line.length() > 2 ) { // Do something... } But I trying to avoid using "magic" constants in code. Usually I use such code: if ( line.length() > strlen("[]") ) { // Do something... } It more readable, but not efficient because of function ca...
I have a method which looks like this: template <typename T> T Test<T>::FindItem(T item) { if(found) //return original value, no problem here else //I want to return NULL here, like: return NULL; } This fails in certain cases at runtime because some of the values can't be converted to NULL in C++ e.g.,...
