Theme Source

Chirpy:

• GitHub repo
• Example and tips/best practices
• Upgrading (using git cherry-pick to pull changes from upstream)

Comment System

• Utterances (configured directly in Chirpy) which uses GitHub issues for post comments

Deviations from Chirpy

Adding Speaking tab

• Added a speaking tab to capture my speaking engagements
• Used an icon from fontawesome for the link in the sidebar

Light Mode Sidebar Background Color

• For my implementation of Chirpy v4.3.0 to v6.1.0, I reverted the light mode sidebar background color to the pre-v4.3.0 color (blue/purple)
• When I updated from Chirpy v6.1.0 to v6.3.0, I decided to use the latest upstream values for the light mode sidebar background color (light gray)

Changelog

• See: #8 where I reverted to the pre-v4.3.0 color (blue/purple)
• In #27, I updated the sidebar-active-color property to the latest upstream value
• In #30, I reverted to the latest upstream values for light mode, which included a change to the sidebar-bg and sidebar-muted-color properties to bring in the light gray sidebar background color

Preview Images

• Chirpy v5.4.0 introduced a strict 40 / 21 (1:91:1) aspect ratio requirement for post's preview images such that they would be cropped if you used a different aspect ratio
• In prior versions, I removed this code so that the post's preview images would still render with their original size
• In June 2023, I updated most of the preview images with the new aspect ratio and brought back preview images to the home page, but I still left out the 40 / 21; line from the post.scss file to account for the images that weren't updated
• In November 2023, I updated to Chirpy v6.2.3 and the preview image logic was moved to commons.scss; removed the 40 / 21; line for the non-updated images

Changelog

• Upstream commit introducing change: 4b6ccbc (Chirpy v5.4.0)
• My changes so that preview image still shimmers before loading, but no image cropping: b282712^..bb1dc1f
  • Really only need to get rid of aspect-ratio: 40 / 21; line
• June 20, 2023: Updated most of the post images to reflect the 1.91:1 aspect ratio since that's the ratio the home page expects for the post preview images
  • I still left out the 40 / 21; line in the post.scss file for the images I didn't update to show the original image size on the post page
• November 1, 2023: In Chirpy v6.2.3, the preview image logic was moved to commons.scss; removed the 40 / 21; line for the non-updated images

Upgrading the Theme

Since we aren't using the theme gem (so we can do customizations), we have to do it the old-fashioned way:

1. Ensure chirpy is set as a remote: git remote add chirpy https://github.com/cotes2020/jekyll-theme-chirpy.git
2. Ensure you have the latest upstream commit: git fetch chirpy
3. Compare the upstream releases and commits to find the first and last release/commit in the range you want to update
   • Recommendation is to use release tag milestones instead of loose commits that aren't part of a release yet
   • You can use this link to compare the changes between two commits in GitHub (same for releases)
4. Start the git cherry-pick:
   • To cherry-pick between a range of release tags (more common): git cherry-pick "v5.6.0..v5.6.1" -m 1
   • To cherry-pick a single commit (not as common): git cherry-pick a887f1d -m 1
   • If getting GPG errors, modify the local git config: git config commit.gpgsign false, but modify it back to true after you are done cherry-picking and rebasing (before amending commit)
5. Review merge conflicts - use a combination of git cherry-pick --skip (for when readme/starter posts are updated) and cherry-pick --continue (to continue after you resolve real merge conflicts)
6. Starting in Chirpy v5.6.0, run: npm run build && git add assets/js/dist -f && git commit -m "update js assets" (docs)
7. Rebase the number of commits you just brought in (you should see icon in VS Code): git rebase -i HEAD~16
   • Leave the top commit as pick but change the rest to squash
   • Update the commit message as appropriate
8. Pay close attention to the terminal output as to which new files are being created and if they should be deleted (new files show up as create mode 100644 file.ext)
   • For example, we wouldn't want to commit a GitHub workflow or issue template that wasn't needed here
   • If there are new files that we don't want to track, delete the files, commit, and run another rebase git rebase -i HEAD~2
   • This command can help with tracking new files in the most recent commit: git diff-tree --compact-summary -r HEAD --diff-filter=A
9. Ensure commit signing is enabled: git config commit.gpgsign true
10. Update author and commit time: git commit --amend --author "Josh Johanning <[email protected]>" --date=now -S
11. Test changes locally before pushing

Building / Testing Locally

bundle install
npm i && npm run build
bundle exec jekyll s

Additional build notes

On macOS

Check ruby version: ruby -v (if ruby 2.6.10p210, then you need to upgrade to 3.0.0+):

1. Install rvm: \curl -sSL https://get.rvm.io | bash -s stable --ruby
   • Uninstall openssl@3 temporarily if you receive errors: brew uninstall --ignore-dependencies openssl@3
2. Check ruby version: ruby -v (should be 3.0.0+)
3. Build and serve the site as normal

On Codespaces

If seeing a racc 1.6.2 permission error, run:

sudo chown -R codespace /usr/local/rvm/gems/ruby-3.1.4/extensions/x86_64-linux/3.1.0
bundle install
