Git Graphable

A powerful Python tool to convert Git commit history into beautiful, interactive flowcharts using the graphable library. Supporting Mermaid, D2, Graphviz, and HTML.

Git Plugin Support

When installed in your PATH, you can use this as a native Git plugin:

git graphable analyze .

🚀 Live Interactive Demo

Features

• Multi-Engine Support: Export to Mermaid (.mmd), D2 (.d2), Graphviz (.dot), or HTML (.html).
• Automatic Visualization: Generates and opens an image (PNG) automatically if no output is specified.
• Advanced Highlighting: Visualize author patterns, topological distance, and specific merge paths.
• VCS Integration: Highlight commits based on pull request/merge request status using gh (GitHub) or glab (GitLab) CLIs.
• Hygiene Analysis: Automatically detect WIP commits, direct pushes to protected branches, squashed PRs, back-merges, and contributor silos. Provides actionable intelligence with exact commit hashes and branch names.
• Issue Tracker Integration: Connect to Jira, GitHub Issues, GitLab Issues, or custom scripts to highlight status desyncs.
• Security First: Configuration trust mechanism enforces security by requiring explicit authorization (use --trust) to execute custom scripts or send credentials from repository-local configs.
• Selective Ignores: Suppress specific hygiene rules for given commit SHAs using the configuration file or --ignore CLI flag.
• Remediation Guide: Detailed guidelines in HYGIENE.md help you reach a 100% score.
• Dynamic Badges: Host live Shields.io badges for Git Hygiene and Code Coverage on GitHub Pages.

Installation

# Using uv (recommended)
uv sync --all-extras

Usage

For a complete reference of all command-line options, see the USAGE.md file. For visual demonstrations of all features, see examples/EXAMPLES.md.

# Basic usage (opens a Mermaid image)
uv run git-graphable analyze .

# Highlight PR status (requires gh CLI)
uv run git-graphable analyze . --highlight-pr-status

# Specify an engine and output file
uv run git-graphable analyze https://github.com/TheTrueSCU/graphable/ --engine d2 -o graph.svg

# Initialize a default configuration file
uv run git-graphable init

# Simplify the graph (only show branches/tags)
uv run git-graphable analyze . --simplify

GitHub Action

Git Graphable can be easily integrated into your GitHub workflows to automatically generate hygiene reports on every push or pull request.

jobs:
  git-hygiene:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
        with:
          fetch-depth: 0 # Required to see full history

      - name: Generate Git Graph Reports
        uses: TheTrueSCU/git-graphable@v0.7.0
        with:
          production_branch: 'main'
          output_dir: 'reports'

Inputs

The following inputs are available for the git-graphable action:

• path
  • Description: Path to the git repository
  • Required: false
  • Default: '.'
• production_branch
  • Description: The main production branch (e.g. main, master)
  • Required: false
  • Default: 'main'
• issue_engine
  • Description: Issue tracker engine (github or jira)
  • Required: false
• github_token
  • Description: GitHub token for issue integration
  • Required: false
  • Default: ${{ github.token }}
• output_dir
  • Description: Directory to save the generated reports
  • Required: false
  • Default: 'git-graph-reports'

The action generates a simplified Mermaid summary (for quick review) and a full interactive HTML graph (for deep-dive auditing), uploading them as workflow artifacts.

Highlighting Options

Git Graphable provides several ways to highlight commits and relationships. Multiple options can be combined to layer information.

For a full reference of the default visual styles and how to customize them, see STYLING.md.

Advanced Examples

Hygiene Analysis

Identify problematic patterns like direct pushes to main, messy WIP commits, back-merges from main, or contributor silos:

uv run git-graphable analyze . --highlight-direct-pushes --highlight-wip --highlight-squashed --highlight-back-merges --highlight-silos

Tip: See HYGIENE.md for a detailed guide on how to remediate these issues and improve your score.

PR Status Highlighting

View the current state of all PRs in your repository graph:

uv run git-graphable analyze . --highlight-pr-status

Divergence Analysis (Hygiene)

Highlight commits that exist in main but are missing from your feature branches:

uv run git-graphable analyze . --highlight-diverging-from main

Issue Tracker Integration

Flag mismatches between your code and your tickets:

uv run git-graphable analyze . --highlight-issue-inconsistencies --issue-pattern "[A-Z]+-[0-9]+" --issue-engine jira --jira-url "https://your-org.atlassian.net"

Customizable Scoring & Styling

Adjust hygiene penalties and visual styles to match your team's workflow:

# Aggressive penalty for direct pushes and custom teal color for critical branches
uv run git-graphable analyze . --check --penalty direct_push_penalty:50 --style critical:stroke:teal

Interactive HTML Viewer

Generate a self-contained HTML file with a searchable graph, details sidebar, and an interactive legend to live-toggle all highlight modes:

uv run git-graphable analyze . --engine html -o graph.html

Configuration

Git Graphable can be configured via a TOML file (.git-graphable.toml or pyproject.toml). CLI flags always take precedence over configuration file settings.

CI/CD

This project uses GitHub Actions for continuous integration and automated publishing:

• CI: Runs just check on all pushes and PRs to main.
• Publish: Automatically builds and publishes to PyPI when a version tag (v*) is pushed.
