Version: unspecified

Status: NEW
Severity: enhancement
Priority: P

minimal example of trailing comma issue
including trailing comma in initializer list causes formatter to switch
indentation style and splits short parameters one per line.
////////////////// BEGIN minimal example input //////////////////
#include <set>
void someFunction( std::set<int> & someSet )
{
// initializer lists inside a constructor
std::set<std::set<int >> firstSet{
{ 1, 2, 3, 5,}, // final comma internal initializer
{ 6, 7, 8,9}
};
std::set<std::set<int >> otherSet = {
{ 1, 2, 3, 5}, // no final comma internal initializer
{ 6, 7, 8,9}
};
auto middleSet = std::set<std::set<int >>{
{ 1, 2, 3, 5, }, // final comma external initializer
{ 6, 7, 8,9},
};
auto finalSet = std::set<std::set<int >>({
{ 1, 2, 3, 5 }, // final comma external initializer
{ 6, 7, 8,9},
});
}
