Run 25919953710 still failed htmltest on both Hugo legs. Two distinct
issues, both pre-existing latent bugs that v0.3.0 made impossible to
ignore:
1. Several theme templates piped paths with a leading slash through
`relURL`, which in Hugo means "this is already absolute — leave it
alone." The intended subpath prefix (`/tsuki/`) was therefore never
added, producing hrefs like `href="/search/"` and `href="/"`. In
production the GitHub Pages mount masked this (broken links from
the page's perspective still happened to resolve under the repo
path most of the time), but htmltest correctly reported them as
broken. Fix by either:
- using `site.Home.RelPermalink` for the home link, or
- piping a string without a leading slash through `relLangURL`
(so Hugo prepends the baseURL path), or
- stripping the leading slash from data-driven URLs first via
`strings.TrimPrefix "/"` and then `relLangURL`.
Affected: header.html, search-button.html, recent-posts.html,
home/hero.html, nav.html, 404.html, search/list.html (Pagefind UI
asset URLs).
2. htmltest has no URL-rewriting feature (the `URLSwap` config in the
prior `d30f50f` "fix" was never read by htmltest — confirmed by
reading htmltest 0.17.0 source). The only clean way to make
internal-link checking work with a `/repo/`-style baseURL is to
mirror the URL structure on disk. CI now builds with
`hugo --destination public/tsuki`, runs Pagefind/smoke/htmltest
against that path, and uploads `exampleSite/public/tsuki/` as the
Pages artifact. The artifact contents become the served site
under `/tsuki/`, identical to the prior behaviour from the
browser's point of view. `.htmltest.yml` drops the dead URLSwap
block.
Also: `tmp/` (htmltest's runtime cache) added to .gitignore so local
runs don't dirty the working tree.
Local verification: 32 smoke checks green; htmltest reports
`✔✔✔ passed, tested 29 documents` against the subpath build.
tsuki (月)
A Hugo blog + personal portfolio theme. The homepage is the portfolio — bio, featured projects, recent posts. Posts live at /post/. Vietnamese-first typography, View Transitions on navigation, Pagefind search, Giscus comments.
月 (tsuki): the moon. Quiet, observed, returned to. Companion to
bonsaiin the same naming family.
Status
v0.1.0 — initial release. See CHANGELOG.md.
Features
- Blog — posts, tags, categories, year-grouped archive, paginated post list
- Personal portfolio on the homepage — driven by
data/profile.yaml+data/projects.yaml, no separate/portfoliosection - Search — Pagefind, zero-runtime, indexed at build time
- Comments — Giscus (GitHub Discussions)
- Vietnamese-first — diacritic-safe typography, native vi date formats, ASCII heading IDs
- Dark mode —
prefers-color-scheme+ persistent toggle, no flash of wrong theme - View Transitions API — smooth same-document navigation in supporting browsers
- Table of contents — auto-mounted on long posts, sticky on wide viewports, IntersectionObserver active highlight
- No build step — pure Hugo + browser ES modules. No SCSS, no TypeScript, no bundler in the theme
- Light — CSS ≤ 4 KB gz, JS ≤ 1 KB gz (excluding Pagefind UI)
Quick start
git submodule add https://github.com/tiennm99/tsuki.git themes/tsuki
echo 'theme: tsuki' >> hugo.yaml
Full installation guide (submodule, Hugo Module, Pagefind setup, required site config): docs/installation.md.
exampleSite/hugo.yaml is a complete working example.

Search and comments
Search uses Pagefind, built post-Hugo via npx pagefind --site public. tsuki pins Pagefind in its own package.json for submodule consumers; Hugo Module consumers install Pagefind in their own site (see docs/installation.md). No runtime dependency.
Comments use Giscus. Generate config at giscus.app and add to params.comments.giscus.* to enable. Defaults to off.
Browser support
Modern evergreen browsers. View Transitions and :has() are progressive enhancements; the theme remains functional without them.
