Levi Neuwirth 0379dda908 Degrade gracefully on corrupt backlinks JSON 
If data/backlinks.json fails to parse, every page that uses the
backlinks context aborts with 'fail'. The JSON is build-generated;
corruption is unlikely but not impossible (interrupted writer, disk
issue). Switch to noResult so the affected pages render without the
backlinks block instead of failing the whole build. The next clean
build regenerates the JSON.

Note: commonplace.yaml and now.yaml deliberately keep fail-fast —
they're hand-edited and silent fallbacks would mask author typos.

README.md

levineuwirth.org

Personal site of Levi Neuwirth — essays, blog posts, poetry, fiction, and music. Built with Hakyll and Pandoc, with a custom build system in build/ and a Haskell + JS + Python toolchain.

Quickstart

make build              # one-shot production build into _site/
make dev                # dev build (drafts visible) + local server on :8000
make watch              # cabal-watch rebuild (drafts visible)
make clean              # cabal run site -- clean
make deploy             # clean → build → sign → push → rsync to VPS

make build always runs make clean implicitly when invoked from make deploy. For day-to-day work, prefer make dev (which serves the site on http://localhost:8000) or make watch (rebuilds on save without a server).

Run make build any time you add or replace binary assets (JPEG/PNG figures, PDFs, music assets). make dev and make watch skip the convert-images.sh / pdf-thumbs preprocessing steps, so a fresh JPEG will have no .webp companion and a fresh PDF will have no thumbnail until a full make build regenerates them. Once the companions exist they survive subsequent make dev runs.

Optional features

  • Similar-links and embeddings. tools/embed.py precomputes page-level embeddings for the "Related" block. To enable:

    uv sync                 # creates .venv with sentence-transformers, faiss-cpu

    The build silently skips embedding when .venv is absent.

  • Client-side semantic search. Downloads a quantized ONNX model used by static/js/semantic-search.js (run once; files are gitignored):

    make download-model

  • Image conversion. make build calls tools/convert-images.sh to produce .webp companions next to every JPEG/PNG. Requires cwebp (libwebp on Arch, webp on Debian/Ubuntu).

  • PDF thumbnails. make pdf-thumbs generates first-page thumbnails for PDFs in static/papers/ using pdftoppm (poppler on Arch, poppler-utils on Debian/Ubuntu). Skipped silently when missing.

Configuration

.env (gitignored, copy from .env.example) holds the GitHub PAT and the VPS rsync target consumed by make deploy. Never commit it.

Repository layout

  • build/ — Haskell build system (Hakyll rules, Pandoc filters, contexts). See build/Filters/ for the Pandoc AST transforms (sidenotes, wikilinks, transclusion, score embedding, viz, …).
  • content/ — authored Markdown (essays, blog, poetry, fiction, music).
  • templates/ — Hakyll/Pandoc HTML templates.
  • static/ — CSS, JS, fonts, images, vendored PDF.js.
  • tools/ — Python tooling (embeddings, importers) and shell scripts.
  • data/ — generated and source data (commonplace.yaml, annotations.json, bibliographies, similar-links.json).
  • nginx/ — vhost snippets shipped to the VPS (security-headers.conf, static-assets.conf, popup-proxy.conf). The live vhost on the VPS is the source of truth; see nginx/vhost.conf.example for the canonical structure and the include order these snippets expect.

Architecture pointers

  • build/Site.hs is the Hakyll rules entry point.
  • build/Patterns.hs defines canonical content patterns shared by Backlinks, Authors, Tags, and Site.
  • build/Compilers.hs wires the Pandoc filter chain into Hakyll.
  • build/Filters/Images.hs does WebP <picture> wrapping; requires the .webp companions produced by tools/convert-images.sh.
