CLAUDE.md

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

Build & Run Commands

# Install dependencies (requires Ruby + Bundler 2.2.19)
gem install bundler -v 2.2.19
bundle install

# Start development server with live reload (http://localhost:4000)
bash run_server.sh
# or directly:
bundle exec jekyll serve -l

# Build for production (outputs to _site/)
bundle exec jekyll build

There are no automated tests. Test changes manually by running the dev server and visually inspecting the output.

Architecture

This is Zikang Xu’s academic homepage — a single-page site built with Jekyll and hosted on GitHub Pages. It derives from the acad-homepage project, which itself is a customized fork of the Minimal Mistakes Jekyll theme.

Content: One page, one file

All content lives in _pages/about.md. The site has no blog posts and no subpages. The navigation bar links to anchor IDs within this single page.

Adding/changing content means editing _pages/about.md. The file uses YAML front matter (permalink: /) and is organized into sections separated by --- horizontal rules with heading IDs (e.g., #about-me, #-news, #-publications).

Navigation entries are defined in _data/navigation.yml as anchor links. When you add a new section heading with an ID to about.md, add a corresponding entry here.

Layout & partials

_layouts/default.html — the only layout; extends Minimal Mistakes compress layout with a sidebar + main content structure
_includes/ — partials for <head>, masthead (nav bar), sidebar (author profile card), analytics, SEO meta tags, and dynamic Google Scholar stats

Customizations on top of the Minimal Mistakes theme

Single-page layout (blog/post features stripped out)
Custom styles in assets/css/main.scss (.paper-box for publication entries, anchor scroll offsets, badges)
collapse.js / collapse.css for accordion/collapsible widgets
academicons icon font for academic social links (ORCID, Google Scholar)
MathJax 2.7.4 for LaTeX rendering (configured in _includes/head/custom.html)
Google Scholar citation stats fetched client-side from jsDelivr CDN
Base target _blank for all external links

Google Scholar crawler

A Python script at google_scholar_crawler/main.py uses the scholarly library to scrape citation data. A GitHub Actions workflow (.github/workflows/google_scholar_crawler.yaml) runs this daily at 8:00 UTC and pushes results to the google-scholar-stats branch. The site reads these stats via jsDelivr CDN (google_scholar_stats_use_cdn: true in _config.yml).

This directory is excluded from the Jekyll build.
