Installation

Using pip (Recommended)

The easiest way to install PR2MD is directly from PyPI:

pip install PR2MD

That's it! The pr2md command will be available in your terminal.

From Source

Alternatively, you can install from source for development or to get the latest unreleased features:

# Clone the repository
git clone https://github.com/tboy1337/PR2MD.git
cd PR2MD

# Install dependencies
pip install -r requirements.txt

# Install the package
pip install -e .

Requirements

• Python 3.13 or higher
• requests library (automatically installed with pip)

Quick Start

After installing via pip, you can immediately start using PR2MD:

# Extract a PR by URL (saves to PR-123.md)
pr2md https://github.com/owner/repo/pull/123

# Extract an Issue by URL (saves to Issue-456.md)
pr2md https://github.com/owner/repo/issues/456

# Save to a custom filename
pr2md https://github.com/owner/repo/pull/123 -o output.md

# Output to console/stdout
pr2md https://github.com/owner/repo/pull/123 -o

Usage

Basic Usage

Extract a PR using its URL (automatically saves to PR-123.md):

pr2md https://github.com/owner/repo/pull/123

Extract an Issue using its URL (automatically saves to Issue-456.md):

pr2md https://github.com/owner/repo/issues/456

Or specify the owner, repository, type, and number separately:

pr2md owner repo pr 123
pr2md owner repo issue 456

Save to Custom Filename

Output the Markdown to a custom filename:

pr2md https://github.com/owner/repo/pull/123 -o pr-details.md
pr2md owner repo pr 123 --output pr-analysis.md
pr2md owner repo issue 456 --output issue-report.md

Output to Console

Output to stdout instead of saving to a file:

pr2md https://github.com/owner/repo/pull/123 -o
pr2md owner repo pr 123 --output
pr2md owner repo issue 456 --output

Verbose Logging

Enable detailed logging for debugging:

pr2md https://github.com/owner/repo/pull/123 --verbose

Reference Downloading

By default, PR2MD automatically scans for and downloads referenced PRs and issues mentioned in the main PR/Issue. You can configure this behavior:

# Set maximum recursion depth for downloading references (default: 2)
pr2md https://github.com/owner/repo/pull/123 --depth 3

# Disable automatic downloading of referenced PRs and issues
pr2md https://github.com/owner/repo/pull/123 --no-references

The --depth option controls how many levels deep the tool will follow references. For example, with --depth 2, if PR #123 references PR #456, and PR #456 references PR #789, the tool will download all three PRs. With --depth 1, it would only download PR #123 and PR #456.

Note: Reference downloading only works when using the default auto-naming (e.g., PR-123.md). If you specify a custom output filename with -o, reference downloading is automatically disabled.

pr2md tboy1337 PR2MD issue 10

This creates files containing all the PR/Issue information in beautifully formatted Markdown documents.

If you want a custom filename:

pr2md tboy1337 PR2MD pr 42 -o pr-42-analysis.md
pr2md tboy1337 PR2MD issue 10 -o issue-10-report.md

GitHub API Rate Limiting

The tool uses the GitHub REST API without authentication by default. GitHub imposes rate limits:

• Unauthenticated requests: 60 requests per hour
• Authenticated requests: 5,000 requests per hour

For most use cases, unauthenticated access is sufficient as the tool makes only a few API calls per PR. If you encounter rate limiting issues, the tool will provide clear error messages.

Future Enhancement: Authentication support is planned for a future release to enable higher rate limits and access to private repositories.

Limitations

• Currently supports only public GitHub repositories (authentication coming soon)
• Rate limited by GitHub API (60 requests/hour without authentication)
• Requires internet connection to fetch data
• Large PRs with extensive diffs may generate very large Markdown files
• Issues can be downloaded, but PRs accessed via the /issues/ endpoint will show as issues (use /pull/ or explicit pr type for PRs)
