Highlighting in IDE is not updated on edit
Environment
- Operating System (e.g. Ubuntu 16.04 x64): Windows 10 Version 1909
- IDE Version (e.g. CLion 2016.3.2): CLion 2020.1
- Cppcheck executable version (
cppcheck --version): 1.90 - Cppcheck plugin version: 1.4.2
Expected behaviour
When editing the code the Cppcheck highlighting should update accordingly.
Actual behaviour
The highlight is not correct until the file has been closed and opened again.
Steps to reproduce the behaviour
#include <string>
template<typename T>
void f(T t) {
(void)t;
}
class A
{
private:
std::string s_{"str"};
};
static void f2(A a)
{
(void)a;
}
int main()
{
A a;
//f<const A>(a); // un-comment for warning template function f()
f2(a);
return 0;
}
If you un-comment that line it should show a warning in the template function, but no error is shown. If you close the file and open it again the warning will be shown. Same when you comment it the warning doesn't go away.
In general, when I test uncommenting code, annotations seem to update correctly.
This appears to be an issue in CLion. The shown problems never change from the initial state when the file was opened. I filed a ticket with CLion - see https://youtrack.jetbrains.com/issue/CPP-22882
