If you have problems with the package please use py -m pip install chronix[cli,dev] --pre --upgrade --user

📦 Usage

The examples below use the public API exactly as implemented in this repository.

Basic elapsed time (BasicTimer)

import time
from chronix import BasicTimer

timer = BasicTimer(auto_start=True)
time.sleep(0.2)
timer.stop()

print(timer.get())            # datetime.timedelta(...)
print(timer.get_readable())   # "0.2 seconds, ..."

Split/lap-like checkpoints with averages (BasicTimer)

import time
from chronix import BasicTimer

timer = BasicTimer().start()
time.sleep(0.05)
timer.split_start()  # start -> now
time.sleep(0.08)
timer.split_end()    # last stop/start -> now

print(timer.get_times())  # [(start, split1), (split1, split2)]
print(timer.tally())      # total seconds as float
print(timer.average())    # average segment as timedelta

Precise delta parsing and formatting (PreciseTimeDelta)

from chronix import PreciseTimeDelta, PreciseTimeFormat

delta = PreciseTimeDelta.parse_timedelta_string("01:02:03.4")
print(delta.nanoseconds())                      # 3723400000000.0
print(delta.to_readable(PreciseTimeFormat.SECONDS))
print(delta.to_clock_string())                  # clock-style representation

Flexible timer with explicit start/stop (FlexTimer)

from chronix import FlexTimer

t = FlexTimer(start_now=False)
t.start(start_at=1.25)  # pre-load elapsed time
t.wait(0.2)
t.lap()                 # record a lap
t.stop()

print(t.get().to_readable())
print(t.show_laps())

Track multiple timers by index (FlexTimer)

from chronix import FlexTimer

t = FlexTimer(start_now=False)
t.start(0, 1)            # start two independent timers
t.wait_ms(20)
t.stop(0)
t.wait_ms(10)
t.stop(1)

print(t.get(0).to_readable())  # shorter
print(t.get(1).to_readable())  # longer

Decorator timing for functions

from chronix import FlexTimer

@FlexTimer.time()
def build_values(n: int) -> list[int]:
    return [i * i for i in range(n)]

build_values(100_000)

Context manager timing for code blocks

from chronix import CPUFTimer

with CPUFTimer():
    sum(i * i for i in range(200_000))

CPUFTimer uses process CPU time, so sleep/wait time is mostly excluded.

Schedule delayed and repeated callbacks

from chronix import FlexTimer

timer = FlexTimer(start_now=False)

timer.after(1.0, print, args=("one-shot fired",))
timer.interval(0.5, 3, print, args=("interval fired",))
timer.schedule_task_at("23:59", print, args=("scheduled for clock time",))

Long-running loop you can stop manually

from chronix import FlexTimer

timer = FlexTimer(start_now=False)
timer.interval(0.25, "inf", print, args=("tick",))

# ... later
timer.stop_loops(0)

Estimate time complexity of a function

from chronix import FlexTimer

def work(n: int) -> int:
    return sum(range(n))

def inputs():
    for n in range(1_000, 20_000, 1_000):
        yield ((n,), {})

print(FlexTimer.complexity(work, inputs()))  # e.g. "O(N)"

FlexTimer.complexity requires optional dependencies: numpy, scipy, and scikit-learn.

CLI examples

Install CLI extras if needed:

pip install "chronix[cli]"

Show help:

chronix help

Run all tests from the CLI:

chronix tests run

Run selected tests in minimal mode:

chronix tests run tests -minimal

Naming convention, dependencies and library information

PEP 8 -- Style Guide for Python Code

For modules I use 'lowercase', classes are 'CapitalizedWords' and functions and methods are 'lower_case_with_underscores'.

Aps Build master

You can use the aps_build_master script for your os to make your like a lot easier. It supports running tests, installing, building and much more as well as chaining together as many commands as you like.

This example runs test, build the project and then installs it

call .\aps_build_master.bat 234

sudo apt install python3-pip
sudo apt install python3-venv
chmod +x ./aps_build_master.sh
./aps_build_master.sh 234
