git-timesheet 0.1.2

Generate Git Timesheets from commit history

Git Timesheet Generator

A Python package to generate git timesheets from commit history, specifically filtering for commits by a particular author.

Overview

This tool analyzes git commit history across multiple repositories and:

• Filters commits by author name/email
• Estimates time spent on each commit (in 15-minute increments)
• Adjusts time based on commit message keywords
• Groups work by day and week
• Formats output as a readable timesheet

Requirements

• Python 3.8+
• pytz library
• click library

Installation

From PyPI

# Create and activate a virtual environment
python -m venv .venv
source .venv/bin/activate  # On Windows: .venv\Scripts\activate

# Install the package
pip install git-timesheet

From Source

# Clone the repository
git clone https://github.com/mcgarrah/git-timesheet.git
cd git-timesheet

# Create and activate a virtual environment
python -m venv .venv
source .venv/bin/activate  # On Windows: .venv\Scripts\activate

# Install in development mode
pip install -e .

Configuration

The tool supports configuration files to set default values. It looks for configuration files in the following locations (in order of precedence):

1. .timesheetrc in the current directory
2. timesheet.ini in the current directory
3. .timesheetrc in the user's home directory
4. timesheet.ini in the user's .config directory
5. config.ini in the user's .config/git-timesheet directory

You can create a configuration file using the ggts init command, or manually create one with the following format:

[defaults]
# Author pattern to filter commits
author = michael mcgarrah

# Default timezone for dates
timezone = US/Eastern

# Minutes between commits to consider them part of the same work session
session_timeout = 60

Command-line arguments always override values from configuration files.

Usage

# Generate a timesheet
ggts generate [OPTIONS]

# Initialize configuration
ggts init

Options

• --base-dir PATH: Base directory containing git repositories (default: current directory)
• --since DATE: Show commits more recent than a specific date (e.g., "2 weeks ago")
• --until DATE: Show commits older than a specific date
• --repos REPO: Specific repository names to include (can be used multiple times)
• --output FORMAT: Output format (text, csv, markdown, or md, default: text)
• --author PATTERN: Filter commits by author (default from config or "mcgarrah")
• --timezone TIMEZONE: Timezone for dates (default from config or "UTC")
• --output-file PATH: Write output to file instead of stdout
• --session-timeout MINUTES: Minutes between commits to consider them part of the same work session (default from config or 60)

Examples

Generate timesheet for the last 2 weeks

ggts generate --since="2 weeks ago"

Generate timesheet for specific repositories

ggts generate --repos food_service_nutrition --repos food-intelligence-app --since="1 month ago"

Generate timesheet for a specific date range

ggts generate --since="2023-01-01" --until="2023-01-31"

Generate timesheet with specific author pattern

ggts generate --author="michael mcgarrah" --since="2 weeks ago"

Generate timesheet in US Eastern timezone

ggts generate --since="1 month ago" --timezone="US/Eastern"

Generate CSV output for spreadsheet import

ggts generate --since="1 month ago" --output=csv --output-file=timesheet.csv

Generate markdown output for pretty formatting

ggts generate --since="1 month ago" --output=markdown --output-file=timesheet.md

Initialize configuration

ggts init

Output Formats

Text Format

Plain text output organized by weeks and days, showing detailed commit information with timezone abbreviations.

CSV Format

Comma-separated values format suitable for importing into spreadsheet applications like Excel or Google Sheets. Includes timezone information for each entry.

Markdown Format

Pretty markdown format with tables organized by week, suitable for viewing in markdown readers or converting to HTML. Includes time ranges and timezone abbreviations for each task to better understand work sessions.

Time Estimation Logic

• Base time: 15 minutes per commit
• Bug fixes/issues: +15 minutes
• New features/implementations: +30 minutes
• Refactoring/improvements: +15 minutes
• Commits close together (within 60 minutes by default) are considered part of the same work session

Timezone Support

The tool supports various timezone formats:

• IANA timezone names (e.g., "America/New_York")
• Common US timezone aliases (e.g., "US/Eastern")
• Short timezone abbreviations (e.g., "EST", "EDT")
• Prefixed short timezone abbreviations (e.g., "US/EST")

Development
