* fix(make-pdf): emoji font fallback in print CSS Emoji code points rendered as .notdef tofu (▯) because the body and @top-center font stacks had no emoji family for Chromium to fall back to. Add SANS_STACK / CJK_STACK / EMOJI_FAMILIES constants (one source of truth per family list) and append the emoji families before the generic sans-serif in the two stacks that can hold emoji. The @bottom-* boxes hold counters / a fixed CONFIDENTIAL string, so they share SANS_STACK without emoji. Non-emoji output is byte-identical. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * feat(setup): auto-install color-emoji font on Linux macOS and Windows ship a color-emoji font; most Linux distros/containers ship none, so make-pdf emits tofu there. ensure_emoji_font() best-effort installs fonts-noto-color-emoji (apt, with dnf/pacman/apk fallbacks) and refreshes the fontconfig cache. Hardened: Linux-only guard, GSTACK_SKIP_FONTS escape hatch, fc-match color=True detection (the broad fc-list query false-matched LastResort), sudo -n so a password prompt fails fast instead of hanging, DEBIAN_FRONTEND=noninteractive, timeout 30 on apt update, and fc-cache under sudo. Warns instead of failing. After a fresh install, refresh_browse_daemon_for_fonts() runs 'browse stop' so the next render spawns a Chromium that sees the new font (font fallback is process-cached). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * test(make-pdf): emoji render gate (pdffonts + pixel proof) pdftotext is a false oracle for emoji: Skia preserves the Unicode in the text cluster even when the glyph drew as .notdef tofu, so extraction passes on a broken render. The gate instead asserts (1) pdffonts shows an emoji family embedded and (2) pdftoppm rasterizes the page to color (measured ~1650 saturated pixels vs ~0 for tofu). pdfimages is not used: macOS embeds color emoji as Type 3 fonts, so it lists nothing even on a correct render. Adds resolvePopplerTool() (DRY resolver, returns null for clean skips) and a fixture exercising FE0F variation-selector emoji. Skips cleanly when poppler tools or a color-emoji font are unavailable. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * ci(make-pdf): install emoji font + run emoji gate on Ubuntu Install fonts-noto-color-emoji before Chromium launches on the Ubuntu leg (macOS already ships Apple Color Emoji), refresh fontconfig, and log the fc-match result. Run the whole make-pdf/test/e2e/ dir so the emoji gate runs alongside the combined-features copy-paste gate. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * harden(make-pdf): emoji gate + font install per adversarial review Codex adversarial pass on the implementation diff flagged five robustness gaps, all fixed here: - emoji-gate skipped green in CI when poppler/font prerequisites were absent, which could let the tofu regression ship behind a green build. Missing prerequisites are now a HARD FAILURE when process.env.CI is set; local dev still skips cleanly. - execFileSync children (make-pdf, pdffonts, pdftoppm, fc-match) had no timeout; a wedged binary or hostile GSTACK_*_BIN override could hang the job past Bun's test timeout. Each child now has a 25s ceiling. - PPM parser trusted header tokens blindly; malformed/variant output gave a silently-wrong count. Now validates magic/dimensions/maxval and pixel-buffer length, handles header comments, throws a hard diagnostic on mismatch. - predictable /tmp paths were collision/symlink-prone; now mkdtempSync under /tmp (kept under /tmp for browse's validateOutputPath allowlist). - only apt-get update was timeout-wrapped; dnf/pacman/apk installs and apt install can hang on locks/mirrors. All package installs now timeout-bound.

Edit the .tmpl and regenerate SKILL.md. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> --------- Co-authored-by: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

# make-pdf: publication-quality PDFs from markdown
|
|
|
|
Turn `.md` files into PDFs that look like Faber & Faber essays: 1in margins,
|
|
left-aligned body, Helvetica throughout, curly quotes and em dashes, optional
|
|
cover page and clickable TOC, diagonal DRAFT watermark when you need it.
|
|
Copy-paste from the PDF produces clean words, never "S a i l i n g".
|
|
|
|
On Linux, install `fonts-liberation` for correct rendering — Helvetica and Arial
|
|
aren't present by default, and Liberation Sans is the standard metric-compatible
|
|
fallback. CI and Docker builds install it automatically via Dockerfile.ci.
|
|
|
|
Emoji need a color-emoji font. macOS (Apple Color Emoji) and Windows (Segoe UI
|
|
Emoji) ship one; most Linux distros and containers ship none, so emoji render as
|
|
empty boxes (▯). `./setup` auto-installs `fonts-noto-color-emoji` on Linux
|
|
(apt/dnf/pacman/apk, best-effort) and the print CSS falls back through Apple /
|
|
Segoe / Noto emoji families. Set `GSTACK_SKIP_FONTS=1` to skip the install (CI
|
|
without sudo, managed or offline machines).
|
|
|
|
## Core patterns
|
|
|
|
### 80% case — memo/letter
|
|
|
|
One command, no flags. Gets a clean PDF with running header + page numbers
|
|
+ CONFIDENTIAL footer by default.
|
|
|
|
```bash
|
|
$P generate letter.md # writes /tmp/letter.pdf
|
|
$P generate letter.md letter.pdf # explicit output path
|
|
```
|
|
|
|
### Publication mode — cover + TOC + chapter breaks
|
|
|
|
```bash
|
|
$P generate --cover --toc --author "Garry Tan" --title "On Horizons" \
|
|
essay.md essay.pdf
|
|
```
|
|
|
|
Each top-level H1 in the markdown starts a new page. Disable with
|
|
`--no-chapter-breaks` for memos that happen to have multiple H1s.
|
|
|
|
### Draft-stage watermark
|
|
|
|
```bash
|
|
$P generate --watermark DRAFT memo.md draft.pdf
|
|
```
|
|
|
|
Diagonal 10% opacity DRAFT across every page. When the draft is final, drop
|
|
the flag and regenerate.
|
|
|
|
### Fast iteration via preview
|
|
|
|
```bash
|
|
$P preview essay.md
|
|
```
|
|
|
|
Renders HTML with the same print CSS and opens it in your browser. Refresh
|
|
as you edit the markdown. Skip the PDF round trip until you're ready.
|
|
|
|
### Brand-free (no CONFIDENTIAL footer)
|
|
|
|
```bash
|
|
$P generate --no-confidential memo.md memo.pdf
|
|
```
|
|
|
|
## Common flags
|
|
|
|
```
|
|
Page layout:
|
|
--margins <dim> 1in (default) | 72pt | 2.54cm | 25mm
|
|
--page-size letter|a4|legal
|
|
|
|
Structure:
|
|
--cover Cover page (title, author, date, hairline rule)
|
|
--toc Clickable TOC with page numbers
|
|
--no-chapter-breaks Don't start a new page at every H1
|
|
|
|
Branding:
|
|
--watermark <text> Diagonal watermark ("DRAFT", "CONFIDENTIAL")
|
|
--header-template <html> Custom running header
|
|
--footer-template <html> Custom footer (mutex with --page-numbers)
|
|
--no-confidential Suppress the CONFIDENTIAL right-footer
|
|
|
|
Output:
|
|
--page-numbers "N of M" footer (default on)
|
|
--tagged Accessible PDF (default on)
|
|
--outline PDF bookmarks from headings (default on)
|
|
--quiet Suppress progress on stderr
|
|
--verbose Per-stage timings
|
|
|
|
Network:
|
|
--allow-network Fetch external images. Off by default
|
|
(blocks tracking pixels).
|
|
|
|
Metadata:
|
|
--title "..." Document title (defaults to first H1)
|
|
--author "..." Author for cover + PDF metadata
|
|
--date "..." Date for cover (defaults to today)
|
|
```
|
|
|
|
## When Claude should run it
|
|
|
|
Watch for markdown-to-PDF intent. Any of these patterns → run `$P generate`:
|
|
|
|
- "Can you make this markdown a PDF"
|
|
- "Export it as a PDF"
|
|
- "Turn this letter into a PDF"
|
|
- "I need a PDF of the essay"
|
|
- "Print this as a PDF for me"
|
|
|
|
If the user has a `.md` file open and says "make it look nice", propose
|
|
`$P generate --cover --toc` and ask before running.
|
|
|
|
## Debugging
|
|
|
|
- Output looks empty / blank → check browse daemon is running: `$B status`.
|
|
- Fragmented text on copy-paste → highlight.js output (Phase 4). Retry with
|
|
`--no-syntax` once that flag exists. For now, remove fenced code blocks
|
|
and regenerate.
|
|
- Paged.js timeout → probably no headings in the markdown. Drop `--toc`.
|
|
- External image missing → add `--allow-network` (understand you're giving
|
|
the markdown file permission to fetch from its image URLs).
|
|
- Generated PDF too tall/wide → `--page-size a4` or `--margins 0.75in`.
|
|
|
|
## Output contract
|
|
|
|
```
|
|
stdout: /tmp/letter.pdf ← just the path, one line
|
|
stderr: Rendering HTML... ← progress spinner (unless --quiet)
|
|
Generating PDF...
|
|
Done in 1.5s. 43 words · 22KB · /tmp/letter.pdf
|
|
|
|
exit code: 0 success / 1 bad args / 2 render error / 3 Paged.js timeout
|
|
/ 4 browse unavailable
|
|
```
|
|
|
|
Capture the path: `PDF=$($P generate letter.md)` — then use `$PDF`.
