Input:
```cpp
/* stl header */
#include <functional>
#include <iostream>
/* modern.cpp.core */
#include <Timer.h>
constexpr int intervallSeconds = 1;
constexpr int secondsToMilliseconds = 1000;
constexpr int exitSeconds = 15;
int main() {
int intervall = 1;
auto intervallTimer = vx::Timer();
intervallTimer.setInterval( [ &intervallTimer, &intervall ]() {
std::cout << "Intervall: " << intervall << std::endl;
intervall++;
if ( intervall >= exitSeconds ) {
intervallTimer.stop();
}
}, intervallSeconds * secondsToMilliseconds );
while ( true ) {
/* Leave the app run infinity */
if ( !intervallTimer.isRunning() ) {
break;
}
}
return EXIT_SUCCESS;
}
```
Will end like that:
```cpp
/* stl header */
#include <functional>
#include <iostream>
/* modern.cpp.core */
#include <Timer.h>
constexpr int intervallSeconds = 1;
constexpr int secondsToMilliseconds = 1000;
constexpr int exitSeconds = 15;
int main() {
int intervall = 1;
auto intervallTimer = vx::Timer();
intervallTimer.setInterval( [ &intervallTimer, &intervall ]() {
std::cout << "Intervall: " << intervall << std::endl;
intervall++;
if ( intervall >= exitSeconds ) {
intervallTimer.stop();
}
},
intervallSeconds * secondsToMilliseconds );
while ( true ) {
/* Leave the app run infinity */
if ( !intervallTimer.isRunning() ) {
break;
}
}
return EXIT_SUCCESS;
}
```
Workaround:
Define a function and do not write the lambda inline. Will keep the formatting.
```cpp
/* stl header */
#include <functional>
#include <iostream>
/* modern.cpp.core */
#include <Timer.h>
constexpr int intervallSeconds = 1;
constexpr int secondsToMilliseconds = 1000;
constexpr int exitSeconds = 15;
int main() {
int intervall = 1;
auto intervallTimer = vx::Timer();
using func = std::function<void( void )>;
const func runOnInterval = [ &intervallTimer, &intervall ]() {
std::cout << "Intervall: " << intervall << std::endl;
intervall++;
if ( intervall >= exitSeconds ) {
intervallTimer.stop();
}
};
intervallTimer.setInterval( runOnInterval, intervallSeconds * secondsToMilliseconds );
while ( true ) {
/* Leave the app run infinity */
if ( !intervallTimer.isRunning() ) {
break;
}
}
return EXIT_SUCCESS;
}
```
