timeship 1.0.1

Easy timing of all kinds of python code.

Timeship

The timeship lets you easily and transparently time execution times within your python code.

Its concept is that you set anchors in your code specifying timing routes. The timeship module will time the specified routes and transparently inform you about their execution time.

installation

Timeship can be installed using pip via:

pip install timeship

demo

Simply execute the following python snippet to see the timeship on sea!

import time
from timeship import timeship


with timeship.Anchor("BuildShip"):
    with timeship.Anchor("CollectMaterial"):
        time.sleep(0.2)
    with timeship.Anchor("CarftHull"):
        time.sleep(0.3)
    with timeship.Anchor("CraftMast"):
        time.sleep(0.4)
        with timeship.Anchor("HoistSail"):
            time.sleep(0.1)

with timeship.Anchor("Sail"):
    time.sleep(0.6)

timeship.plot("timeship_demo")

usage

You have two basic different options to set anchors

the anchor function

The fist option is using timeships anchor function as follows:

# set anchor Arrr
timeship.anchor("Arrr")
# execute code
time.sleep(0.1)
# release anchor Arrr
timeship.anchor("Arrr", release=True)

# set anchor Orrr
timeship.anchor("Orrr")
# execute some code
time.sleep(0.4)
# additionally set anchor Errr
timeship.anchor("Errr")
# execute some other code
time.sleep(0.4)
# release all active anchors by not specifying a name
timeship.anchor()

contexts

The second option is to use contexts

with timeship.Anchor("setup"):
    time.sleep(0.1)

nesting

The timeship also supports nested contexts. Nested timing context can be specified using a slashy (context/subcontext) notation:

timeship.anchor("xdata/load")
time.sleep(0.1)
timeship.anchor()
timeship.anchor("xdata/augment")

or by nesting contexts:

with timeship.Anchor("ydata"):
    with timeship.Anchor("load"):
        # execute ydata loading code
        time.sleep(0.2)
    with timeship.Anchor("augment"):
        # execute ydata augmentation code
        time.sleep(0.3)

or equivalently:

with timeship.Anchor("zdata/load"):
    # execute zdata loading code
    time.sleep(0.2)
with timeship.Anchor("zdata/augment"):
    # execute zdata augmentation code
    time.sleep(0.3)

plotting timing data

At the end of your code, plot the results by by using the plot function. Timeships plotting function (timeship.plot()) creates a directory (specified by the dir argument) with an index.html containing a d3 plot with the timing data which can be viewed through a webbrowser.

timeship.plot(dir="timeship")

This will create a new directory (in this case called "timeship") and store an html page, which contains a clear visualization of the timing data.

Sail on through space and time, Arrr!
