Re: [Qt-creator] Syntax highlighting, template templates
Just as a reminder: using values as template parameters still gets underlined
as an error when a such parameter is used to create a concrete class (see
method foo(Aelements* var) below (or in the attached file)
templateint count
class A {
public:
A() {
std::cout count std::endl;
}
};
templateint elements
void foo(Aelements* var) {
}
templateint elements
void bar() {
std::cout elements;
}

#include iostream
templateint count
class A {
public:
A() {
std::cout count std::endl;
}
};
templateint elements

}

void bar() {
std::cout elements;

int main() {

[Qt-creator] Syntax highlighting, template templates
I've been working with template templates and there are still some bugs in Qt
Creator's syntax highlighter which highlights my code suggesting it has errors
(snapshot from 01/07/2009):
template template typename class Container, typename ElementType
bool printSimulations(ContainerElement container){
}
-- 'ContainerElement' is not a type name
template template typename class Container, typename ElementType
bool printSimulations(ContainerElement container);
-- strangely this doesn't show any error
template template typename class Container, typename ElementType
bool printSimulations(ContainerElement container, const QString path);
-- 'ContainerElement' is not a type name
(adding an additional typename before Container works with the syntax
highlighter, but not with g++ - QtCreator could instead complain about that ;)
)
template template typename class Container, typename ElementType
bool printSimulations(ContainerElement container, const QString path) {
typename ContainerElement::const_iterator i = container.constBegin();
const typename ContainerElement::const_iterator end =
container.constEnd();
while(i != end) {
// do something
++i;
}
}
-- 'ContainerElement' is not a type name at the function declaration
-- and 'Container is not a namespace or class name shown at the
const_iterator lines
Cheers,

Sorry, but do you have class Element and class QString declared before your templates?

Re: [Qt-creator] Syntax highlighting, template templates
It's not declared, because it's (supposed to be) a template template...
but I mixed some things up when I reduced my code to the examples I gave you -
attached is a fixed file also including the value template.
It can not even be used with g++ to prove its correctness (g++ x.cpp).
