GitHub Actions For CI/CD In Research Paper Writing

by Sebastian Müller 51 views

Hey guys! Let's dive into how we can supercharge our research paper writing process using GitHub Actions for CI/CD. This setup will automate building, generating diffs, and releasing our work, making life a whole lot easier. No more manual headaches!

Overview: Automating the Paper Writing Process

Currently, our workflow for writing papers relies heavily on manual execution locally. It's time to bring in GitHub Actions to automate these tasks. This automation aims to:

  • Efficiency in the Review Process: Streamlining the review process is key. By making it super easy to check differences in Pull Requests (PRs), we significantly reduce the burden on reviewers. This means faster feedback loops and a smoother overall review experience. It’s all about making the review process as frictionless as possible, guys!
  • Automation of Release Tasks: Think about the time saved by automating versioning, tagging, and generating final PDFs. Let's face it, manual processes are prone to errors. Automating these steps not only saves time but also minimizes the risk of human error. By automating the generation and publication of the final product, we ensure a consistent and error-free release process.
  • Continuous Quality Assurance: Guaranteeing that every change merged into the main branch has undergone a thorough review and quality check is critical. With automation, we can ensure that all changes meet our quality standards before they become part of the main codebase. This continuous quality assurance process helps maintain the integrity and reliability of our work.

Ultimately, we want to create an environment where writers can focus on the core of their work – the content of the paper itself. By automating the tedious tasks, we free up time and mental space, allowing writers to concentrate on what truly matters: crafting high-quality research papers.

Prerequisites: Setting the Stage for Automation

Before we jump into the workflow, there are a few things we need to set up. It’s like gathering our tools before starting a big project. Here's what you need:

  1. Creating a Dedicated SSH Key Pair (Deployment Key): To allow GitHub Actions to access our DVC remote storage, we need a secure method. This is where a dedicated SSH key pair comes in. We need to generate a passphrase-less SSH key pair. This key pair will serve as our secure gateway. Think of it as a special key that only GitHub Actions can use to access our storage. This ensures that our data transfer is secure and automated.
  2. Registering the Public Key: Once we've generated the key pair, we need to register the public key with our DVC server. This is like giving the server a heads-up that we’ll be accessing it. Specifically, we need to add the public key to the ~/.ssh/authorized_keys file on the DVC server. This step is crucial for establishing a secure connection between GitHub Actions and our DVC storage.
  3. Registering the Private Key: Now, for the secret sauce! We need to register the private key within our repository. This is done in the Settings > Secrets and variables > Actions section of our repository. We’ll save it under the name DVC_SSH_PRIVATE_KEY. Treat this private key like gold – it’s what allows GitHub Actions to authenticate and access our DVC storage securely. Keeping it safe is paramount.

These prerequisites are essential for ensuring a smooth and secure automated workflow. Once these are in place, we're ready to roll!

Proposed Workflow: Automating from Review to Release

We're going to implement two distinct workflows that work together to automate everything from the initial review to the final release. Think of it as a two-part harmony, where each workflow plays a crucial role in the overall process. Let’s break it down:

1. Pull Request Review Support Workflow

This workflow is our first line of defense, designed to assist in reviewing changes before they're merged into the main branch. It's like having a diligent assistant that helps us catch any potential issues early on.

  • Triggers:
    • Whenever a Pull Request targeting the main branch is created. This ensures that every new PR gets the full review treatment.
    • Whenever a new commit is pushed to such a Pull Request. This keeps the review process up-to-date with the latest changes.
  • Executed Jobs:
    1. Environment Setup:
      • First, we checkout the repository’s source code. It’s like setting up our workspace with all the necessary tools and materials. This ensures we have the latest version of the code to work with.
      • Next, we set up the SSH agent using the DVC_SSH_PRIVATE_KEY secret. This is crucial for secure access to our DVC remote storage. It’s like unlocking a secure vault.
      • Then, we run dvc pull to fetch the necessary image data from the DVC remote. This ensures we have all the required assets for our review process.
    2. Code Quality Check:
      • We run latexindent --check to verify that the source code adheres to our established formatting guidelines. This helps maintain consistency and readability across the codebase. It’s like making sure everyone is speaking the same language.
    3. Generating Difference Artifacts:
      • We execute the make diff command to generate a difference PDF and an image report (.zip) highlighting the changes. This gives reviewers a clear picture of what has been modified. Think of it as a visual diff tool that makes it easy to spot changes.
    4. Artifact Upload:
      • The generated difference PDF and image report are then uploaded as workflow artifacts. This makes them easily accessible to reviewers directly within the GitHub interface. It’s like placing all the review materials in a central location.
    5. PR Comment Notification:
      • Finally, a bot automatically comments on the PR, notifying reviewers with links to the uploaded artifacts. This ensures that reviewers are promptly informed and can access the necessary materials with ease. It’s like sending out a notification to everyone that the review package is ready.

This workflow ensures that every Pull Request is thoroughly vetted before it’s merged into the main branch, maintaining the quality and integrity of our work.

2. Automated Versioning & Release Workflow

This workflow kicks in after a PR is approved and merged into the main branch. It takes over the task of versioning and releasing our work, making the process completely hands-free. It’s like having an automated publishing machine that handles all the heavy lifting.

This workflow operates in two coordinated steps:

Step A: Automatic Tagging (On PR Merge)

  • Trigger:
    • When a Pull Request is merged into the main branch. This ensures that every merge triggers the versioning process.
  • Executed Jobs:
    1. Version Number Determination:
      • The merged commit messages are analyzed based on the Conventional Commits specification (feat:, fix:, etc.) to automatically calculate the next version number (e.g., v1.2.1). This ensures consistent and semantic versioning. It’s like having a smart versioning system that understands the nature of the changes.
    2. Tag Creation and Push:
      • A Git tag is created using the calculated version number and pushed to the repository. This marks the release with a specific version. It’s like putting a label on a finished product.

Step B: PDF Build and GitHub Release (On Tag Push)

  • Trigger:
    • When a tag in the v* format is pushed to the repository (automatically triggered by Step A). This ensures that a new release is generated whenever a new version tag is created.
  • Executed Jobs:
    1. Environment Setup:
      • The repository is checked out, and the SSH agent is set up as in Step A. Then, dvc pull is executed to retrieve all data needed for the release. This ensures we have everything we need to build the final product.
    2. Final Artifact Build:
      • The make command (or similar) is executed to build the final release PDF. This compiles all the pieces into the finished paper.
    3. GitHub Release Creation:
      • A new GitHub Release is created using the pushed tag name. This provides a formal release record within GitHub.
      • The built final PDF is uploaded as an asset to the release. This makes the final product easily accessible to users. It’s like publishing the paper for the world to see.

This two-step workflow ensures that our releases are not only automated but also consistently versioned and easily accessible.

Expected Benefits: The Payoff of Automation

By implementing these workflows, we anticipate a significant boost in our efficiency and the quality of our work. Here’s what we expect to gain:

  • Improved Review Quality and Efficiency: Reviewers will have access to formatted diff PDFs and image reports, making it easier to assess changes. This means faster and more thorough reviews. No more squinting at raw code – reviewers can focus on the content and impact of the changes.
  • Enhanced Release Reliability: With releases happening automatically, we eliminate human error in versioning and file attachments. This reduces the risk of mistakes and ensures that releases are consistent and reliable. It’s like having a foolproof release process.
  • Strict Version Control: The history of the main branch and Git tags will always correspond one-to-one with “approved” artifacts. This improves the traceability and reliability of our work. We can always be sure that the version we’re looking at corresponds to a specific release.

In a nutshell, these workflows are designed to make our lives easier, our work more reliable, and our research process more streamlined. Let’s get this done!
