使用FMT的格式范围而无需封闭[]括号
我想用， saparator打印一系列值，但没有[]使用FMT库。
如果我尝试打印出这样的范围，那么
std::vector v {8,4,7,2};
std::cout << fmt::format("{}",v) <<"\n";
输出为
[8、4、7、2]
但是我实际上希望输出为
8、4、7、2
我该怎么做？
我发现的一种方法是执行以下操作
std::cout << fmt::format("{}",fmt::join(v,", ")) <<"\n";
。但是，它是冗长的，它给FMT打了2个电话， 我想避免。这可能吗？
另外，由于性能和可读性原因，我对删除[] 来自FMT产生的字符串。
I want to print a range of values with , separator but without [] using fmt library.
If I try to print out some range like this
std::vector v {8,4,7,2};
std::cout << fmt::format("{}",v) <<"\n";
the output is
[8, 4, 7, 2]
But I actually want the output to be
8, 4, 7, 2
How can I do this?
One approach I've found is to do the following
std::cout << fmt::format("{}",fmt::join(v,", ")) <<"\n";
which does work. However, it's verbose, and it makes 2 calls to fmt,
which I would like to avoid. Is this possible?
Also, due to performance and readability reasons I am not interested in removing [] from the string produced by fmt.

较短的代码是使用
fmt直接执行打印，而不是仅将其用于格式化，然后将结果传递到常规coutiostream方法：格式字符串也包含了新线，
print同时进行格式和打印，因此比以下格式更短/不复杂。The shorter code is to use
fmtto do the printing directly, rather than just using it to format, then passing the result to normalcouttheiostreamway:The format string incorporates the newline as well, and
printdoes both the formatting and printing, so it's markedly shorter/less complex than:
