"""# Git-based Time Tracker.
|
|
|
|
Quick and dirty time tracker on git histories.
|
|
|
|
Uses the simple heuristics that each commit takes precisely one hour of work.
|
|
It will automatically trim commits below one hour if another commit occurred
|
|
less than an hour ago.
|
|
|
|
Usage:
|
|
|
|
```
|
|
python -m git_time_tracker REPO1 REPO2...
|
|
```
|
|
|
|
# Obligatory
|
|
|
|
This tool reports:
|
|
|
|
```
|
|
project Jmaa/git-time-tracker.git 3h 33m (2024)
|
|
```
|
|
|
|
And the ([Hamster](https://github.com/projecthamster/hamster)) manual time tracker reports:
