+| ------------- | ----------------------------------------- |
+| Language      | TypeScript 5.x (strict mode)              |
+| Runtime       | Node.js >=22 (v22.16.0 pinned)            |
+| Package Mgr   | npm >=10.9.2                              |

+
+## Environment
+
+This is a Nix project. Use the provided `flake.nix` to enter a dev shell with Node.js 22 and npm:
+
+```bash
+nix develop
+```
+
+All `npm` commands below must be run inside the dev shell.
+
+## Build, Lint, and Test Commands
+
+```bash
+# Type check and format check (CI validation)
+npm run check
+
+# Auto-format code with Prettier
+npm run format
+
+# Run all tests
+npm run test
+
+# Run a single test file
+npx tsx --test quartz/util/path.test.ts
+
+# Run tests matching a pattern (use --test-name-pattern)
+npx tsx --test --test-name-pattern="typeguards" quartz/util/path.test.ts
+
+# Build the static site
+npx quartz build
+
+# Build and serve with hot reload
+npx quartz build --serve
+
+# Profile build performance
+npm run profile
+```
+
+### Test Files Location
+
+Tests use Node.js native test runner via `tsx`. Test files follow the `*.test.ts` pattern:
+
+- `quartz/util/path.test.ts`
+- `quartz/util/fileTrie.test.ts`
+- `quartz/components/scripts/search.test.ts`
+
+## Code Style Guidelines
+
+### Prettier Configuration (`.prettierrc`)
+
+```json
+{
+  "printWidth": 100,
+  "tabWidth": 2,
+  "semi": false,
+  "trailingComma": "all",
+  "quoteProps": "as-needed"
+}
+```
+
+**No ESLint** - only Prettier for formatting. Run `npm run format` before committing.
+
+### TypeScript Configuration
+
+- **Strict mode enabled** (`strict: true`)
+- `noUnusedLocals: true` - no unused variables
+- `noUnusedParameters: true` - no unused function parameters
+- JSX configured for Preact (`jsxImportSource: "preact"`)
+
+### Import Conventions
+
+```typescript
+// 1. External packages first
+import { PluggableList } from "unified"
+import { visit } from "unist-util-visit"
+
+// 2. Internal utilities/types (relative paths)
+import { QuartzTransformerPlugin } from "../types"
+import { FilePath, slugifyFilePath } from "../../util/path"
+import { i18n } from "../../i18n"
+```
+
+### Naming Conventions
+
+| Element          | Convention   | Example                             |
+| ---------------- | ------------ | ----------------------------------- |
+| Files (utils)    | camelCase    | `path.ts`, `fileTrie.ts`            |
+| Files (comps)    | PascalCase   | `TableOfContents.tsx`, `Search.tsx` |
+| Types/Interfaces | PascalCase   | `QuartzComponent`, `FullSlug`       |
+| Type Guards      | `is*` prefix | `isFilePath()`, `isFullSlug()`      |
+| Constants        | UPPER_CASE   | `QUARTZ`, `UPSTREAM_NAME`           |
+| Options types    | `Options`    | `interface Options { ... }`         |
+
+### Branded Types Pattern
+
+This codebase uses branded types for type-safe path handling:
+
+```typescript
+type SlugLike<T> = string & { __brand: T }
+export type FilePath = SlugLike<"filepath">
+export type FullSlug = SlugLike<"full">
+export type SimpleSlug = SlugLike<"simple">
+
+// Always validate with type guards before using
+export function isFilePath(s: string): s is FilePath { ... }
+```
+
+### Component Pattern (Preact)
+
+Components use a factory function pattern with attached static properties:
+
+```typescript
+export default ((userOpts?: Partial<Options>) => {
+  const opts: Options = { ...defaultOptions, ...userOpts }
+
+  const ComponentName: QuartzComponent = ({ cfg, displayClass }: QuartzComponentProps) => {
+    return <div class={classNames(displayClass, "component-name")}>...</div>
+  }
+
+  ComponentName.css = style           // SCSS styles
+  ComponentName.afterDOMLoaded = script  // Client-side JS
+  return ComponentName
+}) satisfies QuartzComponentConstructor
+```
+
+### Plugin Pattern
+
+Three plugin types: transformers, filters, and emitters.
+
+```typescript
+export const PluginName: QuartzTransformerPlugin<Partial<Options>> = (userOpts) => {
+  const opts = { ...defaultOptions, ...userOpts }
+  return {
+    name: "PluginName",
+    markdownPlugins(ctx) { return [...] },
+    htmlPlugins(ctx) { return [...] },
+    externalResources(ctx) { return { js: [], css: [] } },
+  }
+}
+```
+
+### Testing Pattern
+
+Use Node.js native test runner with `assert`:
+
+```typescript
+import test, { describe, beforeEach } from "node:test"
+import assert from "node:assert"
+
+describe("FeatureName", () => {
+  test("should do something", () => {
+    assert.strictEqual(actual, expected)
+    assert.deepStrictEqual(actualObj, expectedObj)
+    assert(condition) // truthy assertion
+    assert(!condition) // falsy assertion
+  })
+})
+```
+
+### Error Handling
+
+- Use `try/catch` for critical operations (file I/O, parsing)
+- Custom `trace` utility for error reporting with stack traces
+- `process.exit(1)` for fatal errors
+- `console.warn()` for non-fatal issues
+
+### Async Patterns
+
+- Prefer `async/await` over raw promises
+- Use async generators (`async *emit()`) for streaming file output
+- Use `async-mutex` for concurrent build protection

+## Branch Workflow
+
+This is a fork of [jackyzha0/quartz](https://github.com/jackyzha0/quartz) with org-roam customizations.
+
+| Branch      | Purpose                                          |
+| ----------- | ------------------------------------------------ |
+| `main`      | Clean mirror of upstream quartz — no custom code |
+| `org-roam`  | Default branch — all customizations live here    |
+| `feature/*` | Short-lived branches off `org-roam`              |
+
+### Pulling Upstream Updates
+
+```bash
+git checkout main
+git fetch upstream
+git merge upstream/main
+git checkout org-roam
+git merge main
+# Resolve conflicts if any, then commit
+```
+
+### Working on Features
+
+```bash
+git checkout org-roam
+git checkout -b feature/my-feature
+# ... work ...
+git checkout org-roam
+git merge feature/my-feature
+git branch -d feature/my-feature
+```
+
+**Merge direction:** `upstream → main → org-roam → feature/*`
+
+## Important Notes
+
+- **Client-side scripts**: Use `.inline.ts` suffix, bundled via esbuild
+- **Isomorphic code**: `quartz/util/path.ts` must not use Node.js APIs
+- **Incremental builds**: Plugins can implement `partialEmit` for efficiency
+- **Markdown flavors**: Supports Obsidian (`ofm.ts`) and Roam (`roam.ts`) syntax
+- **Pipeline build artifacts**: `scripts/pipeline/_build/` and `scripts/pipeline/deps/`
+  are gitignored — run `mix deps.get` inside `scripts/pipeline/` after a fresh clone

 Quartz is a set of tools that helps you publish your [digital garden](https://jzhao.xyz/posts/networked-thought) and notes as a website for free.

-🔗 Read the documentation and get started: https://quartz.jzhao.xyz/
+This fork adds first-class support for [org-roam](https://www.orgroam.com/) notes via [ox-hugo](https://ox-hugo.scripter.co/).
+
+🔗 Upstream documentation: https://quartz.jzhao.xyz/

+## Quick Start
+
+### Prerequisites
+
+This project uses Nix. Enter the development shell, which provides Node.js 22, Elixir, and Emacs with ox-hugo:
+
+```bash
+nix develop
+```
+
+All commands below must be run inside this shell.
+
+```bash
+npm install
+```
+
+### Building from org-roam notes
+
+Your org-roam notes live in a separate directory. Point `NOTES_DIR` at it:
+
+```bash
+# Export notes to content/ and build the site
+NOTES_DIR=/path/to/notes npm run build:notes
+
+# Export, build, and serve with hot reload
+NOTES_DIR=/path/to/notes npm run serve:notes
+
+# Export only (wipes content/ and re-exports all .org files)
+NOTES_DIR=/path/to/notes npm run export
+```
+
+The export pipeline runs in four phases:
+
+1. **Wipe** `content/` clean
+2. **Export** every `.org` file via `emacs --batch` + ox-hugo → Markdown
+3. **Transform** — post-process the Markdown (citation resolution, etc.)
+4. **Index** — generate a fallback `index.md` if none was exported
+
+#### Citations (org-citar → Zotero links)
+
+org-citar references (`[cite:@key]`) are resolved to clickable Zotero links.
+With Zotero running and the [Better BibTeX](https://retorque.re/zotero-better-bibtex/)
+plugin installed, no extra configuration is needed — the pipeline detects it
+automatically and links directly to the PDF in your library.
+
+```bash
+# Use a local .bib file as fallback when Zotero is not running
+BIBTEX_FILE=/path/to/refs.bib NOTES_DIR=/path/to/notes npm run export
+
+# Control warning verbosity for unresolved keys
+CITATION_MODE=strict NOTES_DIR=/path/to/notes npm run export
+```
+
+| Env var         | Default                  | Purpose                                   |
+| --------------- | ------------------------ | ----------------------------------------- |
+| `BIBTEX_FILE`   | —                        | Path to `.bib` file for citation fallback |
+| `ZOTERO_URL`    | `http://localhost:23119` | Zotero Better BibTeX base URL             |
+| `CITATION_MODE` | `warn`                   | `silent` / `warn` / `strict`              |
+
+### Building without org-roam notes
+
+If you manage `content/` directly with Markdown files:
+
+```bash
+# Build the site
+npx quartz build
+
+# Build and serve with hot reload
+npx quartz build --serve
+```
+
+The site is generated in `public/`. When serving, visit http://localhost:8080.
+
+### Development
+
+```bash
+npm run check    # type check + format check
+npm run format   # auto-format with Prettier
+npm run test     # run tests
+```

+#+title: Example: Image References
+
+This note demonstrates the three image reference scenarios that the pipeline
+must handle.
+
+* Scenario 1: External image (URL)
+
+An image hosted on the web — ox-hugo passes the URL through as-is and no
+local file handling is needed.
+
+#+attr_html: :link "https://encrypted-tbn0.gstatic.com/images?q=tbn:ANd9GcSkzsTuLOt8esM6enoKwkzqA52G3p9hldlf2g&s"
+[[file:quartz-logo-external.png]]
+
+* Scenario 2: Local image (same notes directory)
+
+An image sitting next to this .org file inside the notes directory.
+ox-hugo copies files referenced with a relative path into the Hugo =static/=
+assets tree automatically.
+
+#+CAPTION: Quartz logo (local, same notes dir)
+[[file:quartz-logo.png]]
+
+* Scenario 3: External image (outside notes directory)
+
+An image that lives outside the notes directory entirely — for example a
+shared assets folder or a system path. ox-hugo still copies it into =static/=
+and rewrites the reference.

+
+Madrid has one of the most extensive public transport networks in Europe,
+operated primarily by [[id:crtm][Consorcio Regional de Transportes de Madrid]] (CRTM).
+
+* Modes
+- [[id:metro-madrid][Metro de Madrid]] — 13 lines, ~300 km of track
+- [[id:emt-madrid][EMT Bus]] — urban buses within the city
+- Cercanías — suburban rail run by Renfe
+- Interurbano — regional buses to the wider Community of Madrid
+
+* Ticketing
+A single [[https://www.crtm.es][tarjeta transporte]] (transport card) works across all modes.
+The Multi card covers zones A–C and is topped up at any metro station.

+  Escript entry point for the org-garden pipeline.
+
+  ## Commands
+
+      org-garden serve <notes-dir> [--port 8080] [--ws-port 3001]
+      org-garden build <notes-dir> [--output <path>]
+      org-garden export <notes-dir> [--watch]
+
+  ### serve
+  Development server with watch + live reload. Starts both the org→md
+  watcher and Quartz in serve mode.
+
+  ### build
+  One-shot build for CI/production. Exports org files, runs transforms,
+  then builds static site with Quartz.
+
+  ### export
+  Just export org→md (current pipeline behavior). Use --watch for
+  incremental re-export on file changes.
+
+  ## Arguments
+
+    notes-dir          Path to the directory containing `.org` notes (required).
+                       Also accepts the `NOTES_DIR` env var.
+
+  ## Options
+
+    --output <path>    Output root directory (used as ox-hugo base dir).
+                       Defaults to the `OUTPUT_DIR` env var, or the current
+                       working directory.
+    --content-dir <p>  Output directory for exported Markdown. Defaults to
+                       `<output>/content`.
+    --port <n>         HTTP server port (default: 8080). Only for `serve`.
+    --ws-port <n>      WebSocket hot reload port (default: 3001). Only for `serve`.
+    --watch            After initial batch, watch notes-dir for changes and
+                       incrementally re-export affected files. Only for `export`.
+
+  ## Environment Variables
+
+    BIBTEX_FILE        Path to a `.bib` file used as citation fallback.
+    ZOTERO_URL         Zotero Better BibTeX base URL (default: http://localhost:23119).
+    CITATION_MODE      silent | warn (default) | strict.
+    QUARTZ_PATH        Path to quartz directory (required for serve/build).
+    NODE_PATH          Node.js executable (default: node).

+  Markdown transform: resolves org-citar citation keys to hyperlinks.
+
+  ## Recognised citation syntax (as output by ox-hugo from org-citar)
+
+      [cite:@key]           → org-cite / citar standard (most common)
+      [cite:@key1;@key2]    → multiple citations
+      cite:key              → older roam-style bare cite syntax
+
+  ## Resolution chain (in order)
+
+    1. Zotero (live instance via Better BibTeX JSON-RPC)   — preferred
+    2. BibTeX file (BIBTEX_FILE env var)                   — fallback
+    3. DOI / bare key                                       — always succeeds
+
+  ## Modes (opts.citation_mode)
+
+    :silent  — silently use DOI/bare-key fallback when Zotero+BibTeX fail
+    :warn    — (default) emit a Logger.warning for unresolved keys
+    :strict  — raise on unresolved keys (aborts pipeline)
+
+  ## Format
+
+  Resolved citations are rendered as:
+
+      [Label](url)       when a URL is available
+      [Label]            when no URL could be determined (bare key fallback)
+
+  Multiple semicolon-separated keys become space-separated links:
+
+      [cite:@a;@b]  →  [Author A, 2020](url_a) [Author B, 2019](url_b)
+
+  ## init/1 callback
+
+  Loads the BibTeX file (if configured) once before processing begins,
+  and probes Zotero availability, emitting warnings as appropriate.

Ignacio Ballesteros	d913138726	fix(ox-hugo): serve gitignored content and static assets, fix figure shortcode order - glob.ts: add optional respectGitignore param (default true) so callers can opt out of gitignore filtering for generated directories - build.ts: pass respectGitignore=false when globbing content/ so gitignored-but-generated markdown files are always picked up - static.ts: copy top-level static/ → output/ root with gitignore disabled, mirroring Hugo's convention so ox-hugo images at static/ox-hugo/* are served at /ox-hugo/* as expected by the exported markdown src paths - oxhugofm.ts: run replaceFigureWithMdImg before removeHugoShortcode so the precise figure regex sees the intact shortcode before the generic {{.*}} stripper destroys it; also upgrade figureTagRegex to figureShortcodeRegex which matches the full shortcode form ox-hugo actually emits	2026-02-20 11:11:42 +01:00

Ignacio Ballesteros	a907d6513b	docs(examples): add image reference example note with all three scenarios Adds notes/example-images.org demonstrating how org-mode image links of each kind pass through ox-hugo and land in content/: Scenario 1 — External URL: linked image using #+ATTR_HTML + a local thumbnail as the display image; ox-hugo emits a {{< figure >}} shortcode with a link= attribute pointing to the remote URL. Scenario 2 — Local file (same notes dir): [[file:quartz-logo.jpg]] ox-hugo copies the file to static/ox-hugo/ and rewrites the src to /ox-hugo/quartz-logo.jpg. Scenario 3 — Absolute path outside notes dir: [[file:/abs/path/img.jpg]] ox-hugo copies the file from outside the notes tree into static/ox-hugo/ and rewrites the src identically to scenario 2. Also adds: notes/quartz-logo.jpg — image asset for scenarios 1 & 2 notes-external/ — simulates an assets dir outside notes static/ox-hugo/ added to .gitignore (populated at export time)	2026-02-20 10:09:54 +01:00

Ignacio Ballesteros	511b003da8	Add Elixir markdown pipeline with org-citar citation resolution Introduces scripts/pipeline/, a Mix project that runs as a post-export transformation pass over content/*.md before Quartz builds the site. Pipeline (scripts/export.exs phase 3): - Compiles and loads the Mix project at export time (cached after first run) - Applies a list of Transform modules sequentially over all .md files - Only rewrites files that were actually changed Citations transform (Pipeline.Transforms.Citations): - Resolves [cite:@key] and bare cite:key syntax produced by ox-hugo/citar - Resolution chain: Zotero BBT JSON-RPC → BibTeX file → DOI/bare-key fallback - Zotero probe uses a no-op JSON-RPC call (cayw endpoint blocks indefinitely) - Zotero resolver fetches PDF attachments via item.attachments, producing zotero://open-pdf/... links; falls back to zotero://select/library/items/... - BibTeX resolver parses .bib files with a simple regex parser (no deps) - DOI resolver is the always-succeeding last resort Configuration via env vars: BIBTEX_FILE — path to .bib file for fallback resolution ZOTERO_URL — Zotero base URL (default: http://localhost:23119) CITATION_MODE — silent \| warn (default) \| strict Adding future transforms requires only implementing Pipeline.Transform behaviour and appending the module to the transforms list in export.exs.	2026-02-20 10:00:11 +01:00
