How to measure command/script execution time in xonsh?

Question

How do I measure execution time of command/script in xonsh? In bash I can do it with time eg:

> time sleep 1

real    0m1,002s
user    0m0,001s
sys     0m0,001s

How to do it in xonsh?

There's no shell builtin time in xonsh. I use time(1), which is usually installed in most linux distros, but should be available in your package manager.

  time sleep 1
0.00user 0.00system 0:01.00elapsed 0%CPU (0avgtext+0avgdata 2048maxresident)k
0inputs+0outputs (0major+100minor)pagefaults 0swaps

or if you want it to more closely match the output of the bash builtin

  time -p sleep 1
real 1.00
user 0.00
sys 0.00

or you can roll your own (for wall time)

 import time
 from contextlib import contextmanager
 @contextmanager
°º def _time():
°º     tic = time.time()
°º     yield
°º     print(time.time() - tic)
°º
 with _time():
°º     sleep 1
°º
