PDF Link Checker

Github Action and CLI tool to automatically check all links in a PDF for availability to find dead or broken links.

Usage

Install the package using pip

pip install pdflinkchecker-cli

and use it as a CLI tool

pdflinkchecker .                          # to search for and check all pdfs in the current directory recursively
pdflinkchecker path/to/pdf                # to check a specific file
pdflinkchecker path/to/pdf1 path/to/pdf2  # to check multiple specific files

Exemplary output looks like this

Analyzed /data/dummy1.pdf, found the following types of links/http codes: {200: 13}

Analyzed /data/dummy2.pdf, found the following types of links/http codes: {'mail': 4, 'tel': 4, 200: 49, 'error': 3}

To use the Github Action, create a pdf_link_checker.yml in .github/workflows:

on: [ push ]

jobs:
  check_pdf_links:
    runs-on: ubuntu-latest
    name: Check PDF Links
    steps:
      - name: Checkout
        uses: actions/checkout@v3
      - name: PDF Link Checker
        uses: a-nau/pdf-link-checker@v0.2.0
        with:
          paths: '.'  # checks all PDFs, otherwise specify to file path(s)

To run within Docker

docker build -t pdf_link_checker .
docker run -it --rm --mount type=bind,source=${PWD},target=/data/ --name pdf_link_checker pdf_link_checker /data/.
