Fixed an issue where all the last updated dates were the same on Hugo blogs.

Last updated 1 minute ago

I updated the article, so when I visited the blog and read the articles, I noticed that all the articles were last updated at the same time.

Apparently, if you put lastmod in the article’s meta data, the last updated date will be updated, but I don’t want to do that every time.

Use Git

While researching there, I learned that it seems to be possible using the information of Git.

Configure the following settings with hugo.toml.

enableGitInfo = true [frontmatter] lastmod = ["lastmod", ":git", ":fileModTime",
":default"]

I built it with , but all the articles were last updated 1 minute ago and still remain the same.

I did a lot of research, and it seemed like it could be done by adding an option when building, so I executed it, but it didn’t change 1 minute before the last update.

Check out Git information

It was really strange, so I looked at the commit history of old .md and it was 1 minute ago.

When I tried to figure out why this happened, I discovered that the code was formatted using Github Action, which seemed to be the problem.

When I actually deleted Github Action, the last updated date was released.

Modify Github Action

Modify Action Flow created in I want to run prettier with Github Action.

In the previous Action Flow, all files were formatted, so I modified it to only format changed files.

New version (top):

CHANGED_FILES=$(git diff --name-only ${{ github.event.before }} ${{ github.sha }} -- '*.md')
if [[ -n "$CHANGED_FILES" ]]; then
  echo "$CHANGED_FILES" | xargs prettier --write
else
  echo "No Markdown files changed. Skipping formatting."
fi

Old version (bottom):

prettier --write "**/*.md"

Other improvements have also been made to make it more streamlined.

name: Format Markdown
on:
  push:
    branches:
      - main

permissions:
  contents: write

jobs:
  format:
    runs-on: ubuntu-latest
    steps:
      - name: Check out the repository
        uses: actions/checkout@v3
        with:
          fetch-depth: 0

      - name: Set up Node.js
        uses: actions/setup-node@v3
        with:
          node-version: "18"

      - name: Install Prettier
        run: |
          npm install -g prettier

      - name: Create .prettierrc
        run: |
          echo '{"overrides": [{"files": "*.md", "options": {"proseWrap": "always"}}]}' > .prettierrc

      - name: Format only changed Markdown files
        run: |
          CHANGED_FILES=$(git diff --name-only ${{ github.event.before }} ${{ github.sha }} -- '*.md')
          if [[ -n "$CHANGED_FILES" ]]; then
            echo "$CHANGED_FILES" | xargs prettier --write
          else
            echo "No Markdown files changed. Skipping formatting."
          fi

      - name: Commit changes
        run: |
          git config --global user.name "github-actions[bot]"
          git config --global user.email "github-actions[bot]@users.noreply.github.com"
          git add .
          git diff --cached --quiet || (git commit -m "Format markdown files" && git push origin main)

In the end, it worked.
