Generate mermaid Repo Structure Action

Overview

graph-git-repo is a GitHub Action that automatically generates a visual representation of your repository's structure using the tree command and outputs it as a Mermaid diagram. It allows users to exclude specific files or directories using customizable patterns, and generates a Markdown file (REPO_STRUCTURE.md) along with a MERMAID_DIAGRAM.md for easy visualization.

Features

• Customizable Exclusions: Specify patterns to exclude files or directories from the generated structure.
• Markdown & Mermaid Output: Generates both REPO_STRUCTURE.md and MERMAID_DIAGRAM.md files.
• Artifact Management: Uploads generated files as artifacts for easy download.
• Optional PR Creation: Automatically creates a pull request with the generated files if desired.

How It Works

1. Define the Workflow: Include this action in your GitHub workflow.
2. Customize Exclusions: Specify which files or directories to exclude through the exclude_patterns input.
3. Generate Structure & Diagram: The action runs scripts to create REPO_STRUCTURE.md and MERMAID_DIAGRAM.md.
4. Manage Output: Outputs are uploaded as artifacts, and a PR can be created to include them in your repository.

Usage

To use this action in your repository, include it in your GitHub workflow YAML file. Below is an example configuration:

Example Workflow

name: Test Graph Git Repo

on:
  workflow_dispatch:
    inputs:
      exclude_patterns:
        description: 'Patterns to exclude (e.g., ".git|*.log|node_modules")'
        required: false
        default: '.git|.DS_Store|.idea|*.log|*.tmp|__pycache__'
      depth:
        description: 'Tree depth to consider'
        required: false
        default: '2'
      create_pr:
        description: 'Whether to create a pull request with the generated files'
        required: false
        default: 'false'

jobs:
  test-graph-git-repo:
    runs-on: ubuntu-latest

    steps:
      - name: Checkout target repository code
        uses: actions/checkout@v4

      - name: Use Graph Git Repo Action
        uses: PGSch/graph-git-repo@v1
        with:
          exclude_patterns: ${{ inputs.exclude_patterns }}
          depth: ${{ inputs.depth }}
          create_pr: ${{ inputs.create_pr }}
          openai_api_key: ${{ secrets.OPENAI_API_KEY }}
          github_token: ${{ secrets.GITHUB_TOKEN }}

Inputs

Input Name	Required	Description
exclude_patterns	false	Patterns to exclude from the tree structure (e.g., ".git
depth	false	Specifies the depth of the tree structure to generate.
create_pr	false	Determines whether to create a pull request with the generated files (true or false). Default is true.

Outputs

The action generates two files:

• REPO_STRUCTURE.md: A Markdown-based representation of the repository's structure.
• MERMAID_DIAGRAM.md: A Mermaid diagram of the repository structure.

Required Permissions

This action requires the following permissions to function properly:

• Contents: write (to commit the generated structure back to the repository if create_pr is true).

Advanced Configuration

Customizing Exclusions

You can specify patterns to exclude directly in your workflow file:

with:
  exclude_patterns: '.git|node_modules|*.log|*.env'

Triggering the Action

The action can be triggered manually using the GitHub UI or automatically as part of your CI/CD pipeline.
