Initial Setup (New Machine)

After cloning the repository:

# Install Node.js dependencies (CSS/JS minification tools)
cd utils && npm install

# Install R packages (in R console)
renv::restore()

The utils/purge_css.sh script will auto-install npm dependencies if utils/node_modules/ doesn't exist.

How to update the website

The website is automatically built and deployed via GitHub Actions whenever changes are pushed to the main branch. See .github/workflows/publish.yml for details.

Local Development

To preview changes locally before pushing:

quarto render

This will generate the website in the _site/ directory. You can preview it locally by opening _site/index.html in your browser or by running quarto preview.

Dead link checker

The utils/check_links.sh script scans all rendered HTML files in _site/ for broken links. It checks:

• External links (404 errors, timeouts, connection failures)
• Soft 404s (pages that return 200 but show "not found" content)
• Local file references

If broken links are found, you'll be prompted whether to continue publishing or stop to fix them.

Configuration: Edit utils/linkcheck.config.json to customize:

• siteDir: Directory to scan (default: _site)
• concurrency: Number of parallel requests (default: 20)
• timeout: Request timeout in milliseconds (default: 10000)
• excludePatterns: URL patterns to skip (mailto:, tel:, etc.)
• skipDomains: Domains to skip checking
• softNotFoundPatterns: Patterns that indicate soft 404 pages

Skip the check: Use ./utils/check_links.sh --skip to skip link checking.

It is included to run automatically after quarto render in the _quarto.yml config file.

How to add a new blog post

Manual way

Posts are Quarto documents .qmd files, which are stored in the posts directory. The posts directory is organized by year. To add a new post:

1. Create a new folder in the corresponding year directory, e.g. posts/2024/new-post
2. Create a new .qmd file in the new folder, e.g. posts/2024/new-post/index.qmd

It should have a YAML front matter with the following fields:

---
title: ""
subtitle: ""
categories: []
date: ""
---

3. Write the content of the post in the .qmd file
4. Commit and push the changes to the main branch
5. GitHub Actions will automatically build and deploy the website
6. The new post will be available at https://venpopov.com/posts/2024/new-post/

Automated way

Use the shell command add_new_post. This is a bash script in ~/scripts and also available on my Github
