Git Commits

A Python library for listing Git commits from local repositories with advanced filtering options.

Features

• 📝 List commits from any local Git repository
• 👤 Filter commits by author (name or email, case-insensitive)
• 📅 Filter commits by date range with flexible date parsing
• 🌍 Timezone support for date filtering
• 🌿 Support for searching across all branches
• 🛡️ Robust error handling
• 📦 Clean dataclass-based return objects
• 👥 List unique authors in a repository

Installation

Install from PyPI:

pip install git-commits

Or using uv:

uv add git-commits

For development installation:

git clone https://github.com/theArjun/git-commits.git
cd git-commits
uv install -e .

Quick Start

from git_commits import list_git_commits, get_repo_authors

# List all commits from current repository
commits = list_git_commits(".")

# Print first few commits
for commit in commits[:3]:
    print(f"{commit.short_sha} - {commit.author_name}: {commit.message}")

# List all unique authors in the repository
authors = get_repo_authors(".")
for author in authors:
    print(f"{author.name} <{author.email}>")

API Reference

list_git_commits(repo_path, **kwargs)

List Git commits from a specified local repository with filtering options.

Parameters

• repo_path (str): The absolute or relative path to the local Git repository
• author (str, optional): Filter commits by author’s name or email (case-insensitive partial matching)
• since (Union[str, datetime], optional): Filter commits authored after this date
• until (Union[str, datetime], optional): Filter commits authored before this date
• timezone (str, optional): Timezone string for interpreting string dates (defaults to “UTC”)
• all_branches (bool, optional): If True, search across all branches (defaults to False)

Returns

List of GitCommit objects with the following attributes:

• sha (str): Full SHA-1 hash of the commit
• short_sha (str): First 7 characters of the SHA-1 hash
• author_name (str): Name of the commit author
• author_email (str): Email of the commit author
• authored_datetime (datetime): Timezone-aware datetime when the commit was authored
• message (str): Full commit message

get_repo_authors(repo_path)

Get a list of unique authors from a Git repository.

Parameters

• repo_path (str): The absolute or relative path to the local Git repository

Returns

List of RepoAuthor objects with the following attributes:

• name (str): Name of the author
• email (str): Email of the author

Example

from git_commits import get_repo_authors

authors = get_repo_authors("/path/to/repo")
for author in authors:
    print(f"{author.name} <{author.email}>")

Usage Examples

Basic Usage

from git_commits import list_git_commits

# List all commits
commits = list_git_commits("/path/to/repo")

# List commits from current directory
commits = list_git_commits(".")

Filter by Author

# Filter by author name (case-insensitive)
commits = list_git_commits(".", author="john")

# Filter by email
commits = list_git_commits(".", author="[email protected]")

Date Filtering

Using String Dates

# Commits since a specific date
commits = list_git_commits(".", since="2024-01-01")

# Commits in the last week
commits = list_git_commits(".", since="1 week ago")

# Commits between dates
commits = list_git_commits(
    ".", 
    since="2024-01-01", 
    until="2024-12-31"
)

# Relative dates
commits = list_git_commits(".", since="yesterday")
commits = list_git_commits(".", since="2 months ago")

Using Datetime Objects

from datetime import datetime
import pytz

# Using timezone-aware datetime objects
eastern = pytz.timezone('America/New_York')
since_dt = eastern.localize(datetime(2024, 1, 1))
until_dt = datetime.now(eastern)

commits = list_git_commits(
    ".", 
    since=since_dt, 
    until=until_dt
)

Timezone Support

# Interpret string dates in a specific timezone
commits = list_git_commits(
    ".",
    since="2024-01-01 09:00:00",
    timezone="America/New_York"
)

Search Across All Branches

# Include commits from all branches (including remote-tracking)
commits = list_git_commits(".", all_branches=True)

Combined Filters

# Combine multiple filters
commits = list_git_commits(
    ".",
    author="john",
    since="1 month ago",
    until="now",
    timezone="UTC",
    all_branches=True
)

Working with Results

commits = list_git_commits(".")

for commit in commits:
    print(f"SHA: {commit.sha}")
    print(f"Short SHA: {commit.short_sha}")
    print(f"Author: {commit.author_name} <{commit.author_email}>")
    print(f"Date: {commit.authored_datetime}")
    print(f"Message: {commit.message}")
    print("-" * 50)

Supported Date Formats

The library supports various date string formats:

• ISO dates: "2024-01-01", "2024-01-01 15:30:00"
• Relative dates: "yesterday", "today", "now"
• Relative periods: "1 week ago", "2 months ago", "3 days ago"
• Natural language: Most date strings parseable by dateparser

Error Handling

The library gracefully handles various error conditions:

• Invalid repository paths
• Non-Git repositories
• Invalid date strings
• Permission errors

In case of errors, an informative message is printed and an empty list is returned.

# This will print an error message and return []
commits = list_git_commits("/invalid/path")

Requirements

• Python 3.9+
• GitPython >= 3.1.40
• dateparser >= 1.2.1
• pytz >= 2024.1
