Convert a vector<int> to string with fmt library

Question

How to remove {} from the output?

#include <iostream>
#include <vector>
#include <fmt/format.h>
#include <fmt/ranges.h>
int main () {
    std::vector<int> v = {1,2,3};
    std::string s = fmt::format("{}", v);
    std::cout << s << '\n'; // output : {1, 2, 3}
    return 0;
}

how to remove '{' and '}' in output for the above code and only print : 1, 2, 3

Answer 1

I quote the fmt api:

#include <fmt/ranges.h>

std::vector<int> v = {1, 2, 3};
fmt::print("{}", fmt::join(v, ", "));
// Output: "1, 2, 3"
