Latexindetnt Dockerfile

A lightweight dockerfile for the latexindent plugin.

Latexindent.pl is a great perl script to automatically indent LaTeX files. On Linux, it ships with the texlive distribution. Unfortunately, it only comes with texlive-full which is 5 GB in size.

In this dockerfile I have packaged the minimal dependencies to run the script without a LaTeX distribution. Note that this means that you won't be able to compile within, just check the format. It is particularly useful for CI/CD settings in which a certain style must be reinforced. It can easily be embedded in an existing job (e.g. GH Action) as follows:

jobs:
  check-format:
    runs-on: ubuntu-20.04 
    container: csegarragonz/latexindent:0.0.1
    steps:
      # --- Check out code ---
      - uses: actions/checkout@v2
      # --- Formatting checks ---
      - name: "LaTeX format Check"
        run: latexindent *.tex
      - name: "Test if format is compliant"
        run: git diff --exit-code

The image is publicly available in Docker Hub. PRs are welcome.
