Re: [spyder] Modify the "show elapsed time" option

Dear Spyder developers,

I am a very satisfied user of the Spyder IDE. It looks great and works even better. I use it for all my larger Python assignments and projects. I also greatly enjoy the embedded profiler and pylint. Really superb!

I would however like to propose one minor modification which would greatly simplify testing for run-times. Currently the "show elapsed time" gives us the time since a Python interpreter was started. If I run a script with Spyder I need to remember at which time I pressed F5 and I need to be there when the script finishes to know the exact amount of time it took to run the entire script. I would like to see the "show elapsed time" option modified such that it works like a stopwatch: start from t = 0 when F5 is pressed and hold the timer fixed when a script has finished running.

I know there exist a number of ways to achieve this without modifying the Spyder IDE (use a Python timing function, or use a bash timing function), however I consider this to be a nicer way to achieve it. If there any reasons to reject this proposal I would gladly like to know why and discuss it if possible.

Hello, Aeronaelius.

If you set your script to run in its own dedicated interpreter rather than in the current interactive interpreter you can achieve what you are looking for. With your script open in the editor, hit F6. From the Run Settings dialog that appears, chose "Execute in a new dedicated Python interpreter". Close the dialog and hit F5. The timer will now start at F5 hit and stop when the Python interpreter exits.

Dear Jed,

Yes that is indeed true. However I also like the option to be able to interact with the interpreter after the script has finished. This way I can still access all variables. In that case the timer keeps on running.

Kind regards,

Aeronaelius

Today, Spyder simply monitors the time since each interpreter was born, and I can't honestly think of any sane way that we could modify that behavior so that it reliably predicts the particular portion of the input commands it is supposed to time. I would suggest inserting repeated calls to time.time() into your script and then take the difference.

Well, what I want is already possible in a way. Like you said by setting the script to run in its own dedicated interpreter the timer starts when the interpreter is born and stops when the script is finished. However that is only possible IF you do not add the option to interact with the interpreter after the script has finished (as I said before). So basically what could be done is to do the same for when the interaction option is selected.

Another way is to make Spyder print the elapsed time to the console only once when the script has finished (having that as a Spyder in-build option rather than writing the code yourself).

I'd say that would be convenient. I guess the main problem here is to detect if a script is finished with selected interaction option. If I understand it right, the interpreter doesn't signal when script finished and can not detect the phase itself.

IPython has a magic called %timeit that does exactly what you need. We could add an option to our Preferences pane to run it by default.

Cheers,
Carlos
