Feature request -- print elapsed time #267

Ninja is so fast that I always run it under the time command to see how fast it actually is. Can ninja please print the time it's been working for itself?

You can use "-t stats" to print some timing information.

But "time ninja" will always be a more accurate time measurement, because it takes some time for the kernel to load the binary and ld.so to load libc etc. which all happen before ninja could start measuring its own time.

There does not seem to be such a tool. It says a unknown tool 'stats', and doing a ninja -t list does not show anything that would seem to be statistics-related.

UPD: there seems to be an issue about statistics, so I would presume such tool definitely does not exist.

The flag you are looking for is -d stats.

$ ninja -d stats
