Updating Hog to a Newer Release

Warning

Outdated Documentation! This documentation version is out of date. Please check the latest version 2026.1.

This guide will help you update Hog to your desired version. It assumes you already have a repository managed with Hog and hosted on GitLab or GitHub.

Preparation

On your project’s website, create a new branch starting from master and open a merge/pull request for your changes.

Note

If you are already working on a branch in your HDL repository, you can update Hog within that branch. (Alternatively, you can create a new branch locally and open the merge request on the website later.)

Updating the Hog Submodule

Check out your branch and navigate to the Hog directory. To update Hog to the latest version, run:

cd Hog
git checkout master
git pull

To verify the version you have checked out, use:

git describe

You should see something like HogYYYY.n (e.g., Hog2020.1) or vX.Y.Z (e.g., v1.2.3).

If you want to update to a specific version, visit the Hog releases page, choose your desired version (e.g., v1.2.3), and run:

cd Hog
git checkout v1.2.3

Updating the GitLab CI Configuration

If your project uses GitLab CI, you need to update your .gitlab-ci.yml file to reference the new Hog version. If you are not using GitLab CI, you can skip this step.

Go back to your repository root and edit .gitlab-ci.yml with your preferred editor:

cd ..
vim .gitlab-ci.yml

At the beginning of the file, in the include section, you will see a reference similar to:

include:
  - project: 'hog/Hog'
    file: '/hog.yml'
    ref: 'vA.B.C'

Update the ref field to match the new version you have checked out:

include:
  - project: 'hog/Hog'
    file: '/hog.yml'
    ref: 'vX.Y.Z'

If you are using the dynamic CI, the include section will look like:

include:
  - project: 'hog/Hog'
    file: '/hog-dynamic.yml'
    ref: 'vX.Y.Z'

Save and close the file.

Finalizing the Update

Add the updated files (Hog submodule and .gitlab-ci.yml), commit, and push your changes:

git add .gitlab-ci.yml Hog
git commit -m "Update Hog to vX.Y.Z"
git push

Finally, go to your project’s GitLab/GitHub website, open a merge request for your branch (if you haven’t already), and merge it once the CI passes.
